Title: Computer neural network regulatory process control system and method
Inventor: SKEIRIK RICHARD D
IPC: G06N3/04
Filed: 1991-07-25
Abstract: A computer neural network regulatory process control system and method allows for the elimination of human operator from real time control of the process. The present invention operates in three modes: training, operation (prediction), and retraining. In the training mode, training input data is produced by the control adjustment made to the process by the human operator. The neural network of the pres-ent invention is trained by producing output data using input data for prediction. The output data is compared with the training input data to produce error data, which is used to adjust the weight(s) of the neural network. When the error data is less than a preselected criterion, train-ing has been completed. In the operation mode, the neural network of the present invention provides output data based upon predictions us-ing the input data. The output data is used to control a state of the pro-cess via an actuator. In the retraining mode, retraining data is supplied by monitoring the supplemental actions of the human operator. The retraining data is used by the neural network for adjusting the weight(s) of the neural network.

Title: Bidirectional selectively actuatable lighter
Inventor: MCDONOUGH JAMES M
IPC: F23Q2/28
Filed: 1990-12-21
Abstract: A selectively actuatable child resistant lighter device is disclosed which includes a body (12) defining reservoir (15) for containing a combustible gaseous medium (9) such as butane, and having a valve arranged to be selectively actuated between a normally closed position and an open position which permits the exit of the gaseous medium. Such child resistant lighter can selectively produce sparks at a location proximate to the gaseous medium exit to ignite the gaseous medium. A safety mechanism normally prevents actuation of the valve to the open position. Such child resistant lighter device embodies a resiliently releasable safety latch which prevents the actuation of the valve actuator to the open position. The safety latch (16) is selectively movable to a plurality of positions out of interference with the valve actuator, so that the gaseous medium may be released and ignited by the sparks. The safety latch is resiliently structured and mounted such that once a flame is produced and the valve actuator (14) is released, the safety latch returns to its closed or locked position to prevent actuation of the valve to the open position by prevention of the pivotal motion of the valve actuator. To "re-use" the lighter, the safety latch must again be moved to one of the open or unlocked positions so that the valve actuator can be opened for subsequent ignition of the gaseous medium. Such mechanism is difficult for a young child to light, but is capable of actuation by adults.

IPC: B31B50/62
Filed: 1992-11-20
Abstract: ABSTRACT A multi page mailer type business form is constructed by applying a first adhesive pattern to the top sheet bottom face perimeter areas, a second adhesive pattern to the bottom sheet top face perimeter areas, and applying third and fourth adhesive patterns to the middle sheet top and bottom face perimeter areas respectively. Variable information is printed on the top, bottom and middle sheets including machine readable identification information (bar code) which is common to the sheets that are to be assembled into a final multi page mailer. The set is accumulated, and verified by scanning the identification information, and then the perimeter adhesive patterns are sealed. The adhesive is preferably pressure sensitive adhesive, and the final mailer produced has a book-like construction. The adhesive patterns are such that the top and bottom sheets can be provided in a stack without the perimeter adhesive patterns aligning, and the middle sheets can be provided in a separate stack. A four-part (or more) form may be constructed by slitting two sheets with adhesive patterns into four.

Abstract: ABSTRACT OF THE DISCLOSURE    A power transmitting device for converting a reciprocating motion of a piston into a rotational motion.  The piston is reciprocated in a cylinder of a reciprocating engine to perform suction, compression, explosion and exhaust.  The power transmitting device includes a connecting member supported to the piston; a guide member for linearly guiding the connecting member; a power transmitting member supported to the connecting member; a cam member having a cylindrical surface on which a cam having a predetermined cam curve is formed, the cam being engaged with the power transmitting member; and a drive shaft integral with the cam member.  The drive shaft is rotated by a linear reciprocating motion of the power transmitting member in a plane perpendicular to a direction of the linear reciprocating motion of the power transmitting member.  With this arrangement, the drive shaft extends in a direction parallel to a reciprocating direction of the piston, thereby making the construction of the power transmitting device greatly compact in a radial direction thereof.  Further, the power transmitting device is equivalent to a power transmitting device including a primary reduction gear having a reduction ratio to be decided by the cam curve of the cam, thereby smoothly obtaining a high torque.
