Abstract: Apparatus for forming elongated metal cans from relatively short cups by utilizing a reciprocating ram to drive the cups one at a time through a die pack, is pro-vided with a continuously rotating feeder that transfers the cups from the exit of a gravity feed chute to a re-ceiving station where each cup is indexed for engagement by the ram as it moves forward in its working stroke. The feeder rotates through one complete revolution for each forward-return cycle of the ram and during each revolution thereof a pocket in the feeder receives a cup from the chute, which cup then moves along a curved guideway to a receiving station.  Prior to being engaged by a registry formation at the receiving station the cup is engaged by a stripper that removes the cup from the feeder pocket.  The feeder continues to drive the cup toward the registry formation while the cup is being stripped from the feeder pocket.  A formation on the feeder maintains the cup in engagement with the registry formation while the cup is initially engaged by the ram during forward movement thereof.

Title: Energy absorbing device and torque measuring apparatus therefor
Inventor: DECONTI JOHN P
IPC: F16D65/12
Filed: 1990-09-26
Granted: 1996-05-07
Abstract: In a dynamometer, an internally cooled disc is utilized in a braking system which can apply a large amount of torque for an extended period of time.  A hollowed braking disc comprising individual cooling cells is employed.  Cooling liquid is injected into the center of the braking disc and, by centrifugal force, is forced into the cooling cells via a flow tube ring.  The cooling liquid vaporizes in the cooling cells thus absorbing the heat generated.  The vapor escapes the disc via vent holes.  A unique torque measurement system is also utilized with its braking system.  A result force, formed by the sum of individual forces upon braking pistons within the braking system, is measured utilizing a strain gauged load cell.  The strain gauged load cell is strategically positioned to measure a resultant displacement of the braking caliper due to the applied torque.

Title: Computer neural network process measurement and control system and method
Inventor: SKEIRIK RICHARD D
IPC: G05B13/02
Filed: 1991-07-25
Granted: 2003-04-22
Abstract: A computer neural network process control system and method provides predicted values to a controller used to control a process for producing a product. The predicted value is produced by a neural network provided with stored input data from a historical database. The neural network is configured by a developer using a neural network configura-tion stage and step. The neural network is trained using training data stored in the historical database, which is com-pared with the predicted value produced by the neural ne-twork using input data obtained at a time associated with the time of the training data. An error signal is produced by the comparison of the predicted value with the training data, the error signal is used to train the neural network, and is al-so used to determine (1) whether the predicted values of the neural network should continue to be used by the controller, and (2) to retrain the network. Predicted values are thus pro-duced by the neural network which have a close correlation to the training values training data.
