Title: Injection molding controller with controlled variable learning
Inventor: STROUD JAMES WILLIAM III
IPC: G05B19/39
Filed: 1991-05-21
Granted: 2001-09-18
Abstract: A controller for an injection molding machine controls the injection ram by means of profiles having segments with programmable setpoints. The injection molding machine is initially controlled during each segment in an open-loop manner. Closed-loop control is then adopted. The difference between the open-loop and the closed-loop output to the injection molding machines valves is used to change the setpoints with each cycle to improve the open-loop accuracy over time. The learning rate of change of the open-loop setpoints decreases after the initial correction.      During the open loop control, the closed loop control is deactivated to prevent it from being affected by the previous open loop error.

Title: Plasticizing assembly for use in an injection molding machine
Inventor: HEHL KARL
IPC: B29C45/23
Filed: 1991-12-02
Granted: 1994-11-01
Abstract: The strokes performed in the direction of the injection axis by a valve-actuating cylinder disposed near the rear portion of the plasticizing cylinder are transformed by a motion-deflecting lever into opening and closing movements of the valve needle. The motion-deflecting lever is disposed within the protective skeleton, which surrounds the plasticizing cylinder. Said lever is pivoted to said skeleton by supporting pivot means. The valve needle extends rearwardly to a location which is radially aligned with the feed screw when it is in its foremost position. The valve needle extends in a needle-guiding bore, which is formed in the plasticizing cylinder and has a relatively wide rear portion having an open rear end at a location which is radially aligned with the back flow valve when the feed screw is in its foremost position. Owing to that design the means by which the movement effected by the valve-actuating cylinder in the direction of the injection axis is deflected and transmitted to the valve needle, which is inclined relative to the injection axis, can be manufactured at much lower cost.

Filed: 1992-01-09
Granted: 1994-10-11
Abstract: A temperature monitoring unit that allows to improve temperature monitoring sensitivity of a rotary heating element and to monitor temperature of a larger heating element is provided.  The temperature monitoring unit is comprised of a mirror which is provided in the vicinity of a rotary heating element, reflects infrared rays generated from a thermal point on the heating element toward outside in the radial direction thereof and reciprocates linearly in the radial direction, a condenser lens provided outside of the heating element for condensing the infrared rays reflected by the mirror, an infrared sensor provided on the condenser section, a slit plate which is provided on the mirror side of the lens and which has an opening which is long in the direction approximately perpendicular to the surface of the heating element, and an image processor for inputting the output of the infrared sensor.  The sensitivity is improved because infrared rays from around the thermal point of the heating element is blocked by the slit plate.  Moreover, the visual field becomes long in the radial direction of the heating element, so that the moving speed of the mirror can be increased.

Title: Enhanced detection of microorganisms in samples
Inventor: MONTHONY JAMES F
IPC: C12M1/20
Filed: 1993-09-03
Granted: 2001-02-13
Abstract: This invention describes a method for the rapid identification of the presence of microorganisms in a sample.      Briefly, in the method of this invention the sample container is divided into a plurality of discrete zones, each of which can be separately monitored for microbial presence. When a sample is placed into this container, detection is simplified as the volume monitored is low (as compared with the sample); since microbial detection is a concentration dependent phenomenon, the speed with which the presence of microbial contamination can be detected is increased.

Title: Cereal cooker control method and apparatus
Inventor: MCCULLOUGH NANCY JANE
IPC: G05D7/06
Filed: 1994-08-03
Granted: 2004-11-23
Abstract: A control process and apparatus enable operation of a pressurized continuous cereal cooker and discharge auger with decreased steam utilization. An electric motor advances the cooked cereal mass through a pressurized zone comprising a quick-opening valve, preferably a butterfly valve. The current drawn by the electric motor is monitored to sense the accumulation of cooked cereal mass at the valve. A process signal, representative of the current drawn by the motor, is compared to a reference signal, representative of a selected value representative of a current higher than that required to turn an empty auger.      A control signal based on the comparison of the first signal and the reference signal is then generated to open or close the valve in response to the control signal. When the process signal drops below the reference signal, the valve is closed.
