Method And Apparatus For Controlling A Mold Melt-Flow Process Using Temperature Sensors

View page
US Patent:
6649095, Nov 18, 2003
Filed:
Nov 5, 2001
Appl. No.:
10/008083
Inventors:
Frederick J. Buja - Rochester NY, 14617
International Classification:
B29C 4578
US Classification:
264 406, 2643281, 425144, 425145
Abstract:
The present invention is a method and apparatus for controlling a mold flow process using inner (impinge) and/or edge temperature sensors, wherein articles processed in a constraining mold cavity, having a constant melt “shrink” quality, can be obtained even with fluctuations in resin “melt” properties (flowability). At least one temperature-dependent output or “trigger” signal is sampled, and the level of the signal (e. g. , temperature) initiates at least one step in the molding cycle. Using a sampling circuit, thermal waveforms are obtained from thermal sensor array data such that if a sequence of melt temperature set-point trigger times fluctuates outside control limits, then the process melt-flow is judged as a hotter/faster melt-flow or cooler/slower melt-flow injection process.

Aug 14, 2007
Appl. No.:
11/838491
Inventors:
Frederick Buja - Rochester NY, US
International Classification:
A61B 5/01

G01K 7/02
US Classification:
600549000, 374179000, 600301000, 374E07004
Abstract:
Disclosed are systems and methods for enabling the acquisition of physiological parameters of a mammal or other specimen using thermo-mechanical responses (e.g., temperature, pressure and alternatively acceleration, pulse, position). In accordance with one example embodiment, a monitoring device for wired and/or wireless sensors is used to acquire a series of sensor signals that are attached to achieve the physiological measurements of a mammal vital signs is provided. The device includes a Temperature-Pressure (T-P) sensor configured to attach to respiration, vascular pressure and audio points of the mammal in a manner suitable for obtaining the acquired individual sensor electrical signal. The sensor system is configured to attach to alternative locations of the specimen in a manner suitable for obtaining electrical signals in communication with a signal receiver and transmitter. Physiological parameters, such as those associated with vital signs (temperature, pulse, respiration, etc.), can be obtained using the monitoring device and associated sensors.

Filed:
May 16, 2011
Appl. No.:
13/108906
Inventors:
Frederick J. Buja - Rochester NY, US
International Classification:
A61B 5/00
G06F 15/00
G01K 13/00
US Classification:
600301, 374143, 702138, 374E13001

Apparatus For Data Acquisition And Application In An Injection Molding Process

View page
US Patent:
49041720, Feb 27, 1990
Filed:
Jun 20, 1988
Appl. No.:
7/208930
Inventors:
Frederick J. Buja - Rochester NY
Assignee:
Eastman Kodak Company - Rochester NY
International Classification:
B29C 4577
B29C 4580
US Classification:
425140
Abstract:
An injection molding apparatus utilizing an injection molding machine having a pair of separable mold elements forming a mold cavity therebetween and arranged for separation for the removal of the molded product, means for opening and closing the mold elements, and injection means for injecting the moldable material into the mold cavity at a first pressure and for exerting a second pressure on the moldable material as it cures in the cavity. The apparatus provides data acquisition and application in the operation of the injection machine. The apparatus includes means for measuring the separation of the mold elements during the injection of the moldable material, and means for causing the injection pressure from the first pressure to the second pressure upon detecting a predetermined separation known to produce an acceptable product. Means is provided for maintaining the second pressure until the thermoplastic material has cured. The mold is then opened and the cured product is ejected.

Method Of Precision Volumetric Control Of A Moldable Material In An Injection Molding Process

View page
US Patent:
47675799, Aug 30, 1988
Filed:
Nov 2, 1987
Appl. No.:
7/115675
Inventors:
Frederick J. Buja - Rochester NY
Alan B. Miller - Scottsville NY
William H. Sherwood - Victor NY
James J. Wenskus - Rochester NY
Assignee:
Eastman Kodak Company - Rochester NY
International Classification:
B29C 4557
US Classification:
264 405
Abstract:
A method of operating an injection molding machine having a pair of separable mold elements forming a mold cavity therebetween with means for opening and closing the mold elements with means for introducing a moldable material into the mold cavity at a first pressure and for exerting a second pressure on the moldable material as it cures in the cavity. The method controls the molded product and comprises the steps of closing the mold elements and introducing a moldable material into the mold cavity. The separation of the mold elements is measured during the injection of the moldable material and a predetermined separation of the mold elements is detected. Upon detecting the predetermined separation the pressure is changed from the first pressure to the second pressure and the separation of the mold elements is continued. Measurement of mold element separation is continued and the cessation of the increase in the separation of the mold elements is detected. A determination is made whether or not the cessation occurs within a predetermined separation window.

US Patent:
47673001, Aug 30, 1988
Filed:
Nov 2, 1987
Appl. No.:
7/115676
Inventors:
Frederick J. Buja - Rochester NY
Alan B. Miller - Scottsville NY
William H. Sherwood - Victor NY
James J. Wenskus - Rochester NY
Assignee:
Eastman Kodak Company - Rochester NY
International Classification:
B29C 4577
B29C 4580
US Classification:
425140
Abstract:
A molding machine having a pair of separable mold elements forming a mold cavity therebetween is arranged for separation along a part-line. Means is provided for controlling the molded product which comprises means for measuring the separation of the mold elements resulting from the introduction of the moldable material into the mold cavity. Means is provided for detecting a predetermined separation of the mold elements, and means is provided for changing the pressure from the first pressure to the second pressure in response to the detection. The separation measuring means is arranged to measure the separation of the mold elements following changing the pressure. Means is provided for sensing when the separation of the mold elements stops increasing and for determining whether the cessation occurs within a predetermined cessation window. Means is provided to generate a signal if the cessation is not within the window to indicate that the cycle has exceeded the product limit. If the cessation is within the window, the second pressure is maintained until the material has cured.

Modular Rotary Molding Machine

View page
US Patent:
43701248, Jan 25, 1983
Filed:
Jun 17, 1981
Appl. No.:
6/274472
Inventors:
Frederick J. Buja - Rochester NY
International Classification:
B29F 100
US Classification:
425556
Abstract:
This machine has a turret which rotates about a horizontal axis on a frame that is movable into and out of a loading position adjacent a rotary extruder. The turret comprises a tubular shaft, a plurality of axially spaced, circular plates secured to the shaft coaxially thereof, and a plurality of identical, radially projecting panels that are secured in registering radial slots in the circular plates. A separate mold is mounted in the angular space between each pair of adjacent panels, and comprises a stationary section fixed to one of the circular plates for rotation therewith, and a movable section mounted for reciprocation by a collapsible linkage into and out of a closed position against the associated stationary section. As each mold rotates past the loading station the associated linkage closes the movable mold section, a supply of molten molding material is then fed by the extruder to an axial bore in the stationary section of the mold, a hydraulically actuated ram then enters the now-loaded bore and forces the molding material into a cavity in the mold, the ram is then withdrawn, and thereafter the mold sections are separated and the molded part is ejected from the turret. The size of the turret can readily be increased or decreased merely by changing the overall sizes of the panels and the associated supporting plates.
