Patent CA-2139037-A1 (CA)
Title: Puck stopping device
Inventor: TROTTIER LUC
IPC: A63B69/00
Filed: 1994-12-23
Abstract: A device for stopping a puck travelling in a given direction along a predetermined trajectory comprises two belts mounted on respective pairs of pulleys.  The two belts comprises respective belt runs generally facing each other,  situated on opposite sides of the predetermined trajectory, and converging in the given direction of travel to form a V-shaped constriction.  In operation, the puck travelling along the predetermined trajectory  reaches  the V-shaped constriction and squeezes between the two convergent belt runs whereby the resistance to movement of the puck increases and the puck is decelerated until it is stopped.  Stopping of the puck is made quiet by the resiliency and flexibility of the material forming the two belts.  Advantageously, the puck stopping device comprises first and second belt support mechanisms on which the respective belts and pulleys are mounted, these belt support mechanisms being articulated on pivots to squeeze the puck between the two belt runs while the two belts are driven through the pulleys for thereby propelling the puck in view of returning it to a start position thereof.

Title: Lanscape edging
Inventor: REUM DONALD J
IPC: A01G9/28
Filed: 1995-04-06
Abstract: Landscape edging formed by plastic extrusion is disclosed consisting of a body member adapted for partial insertion in the ground with a first portion lying above the ground and a second portion lying below the ground. A top rail member extends longitudinally along the top of the body member. An anchoring member extends along the bottom of the bottom member taking the form of a hollow triangle. To facilitate packaging of the landscape edging in coils, the anchoring member is formed with a longitudinal tongue on one side and a longitudinal groove on the other. This enables the edging to be packaged in coils that are tied or wound at two or more points rather than packaging the coils in a cardboard box or sleeve.

Patent CA-2152866-A1 (CA)
Inventor: SELLERS CHARLES A
IPC: G06F1/16
Filed: 1995-06-28
Abstract: A compact notebook computer, when opened, exposes a keyboard structure in a folded storage and transport orientation in which opposite end segments of the keyboard are inwardly pivoted onto a central segment of the keyboard, and the keys are in fully retracted, inoperative positions.   To use the keyboard its end segments are outwardly pivoted to a use orientation in which they project outwardly beyond opposite ends of the computer base housing and are vertically aligned with the central keyboard segment.  A top side portion of the keyboard structure is then horizontally shifted in  a  first  direction  relative  to  a  base  portion thereof.    This  shifting  automatically  raises  the keyboard keys to fully extended operative positions thereof,  thereby readying the keyboard for typing thereon.   To return the keyboard structure to its storage and transport orientation, the top keyboard side portion is horizontally shifted relative to the base portion in a second direction opposite to the first direction.  This shifting automatically retracts the keys to their original inoperative positions.  The opposite keyboard end segments are then folded inwardly onto the central segment to permit the computer lid housing to be closed again.

Title: Method and apparatus for analyzing a neural network within desired operating parameter constraints
Inventor: KEELER JAMES DAVID
IPC: G05B13/02
Filed: 1994-03-02
Abstract: A distributed control system (14) receives on the input thereof the control inputs and then outputs control signals to a plant (10) for the operation thereof. The mea-sured variables of the plant and the control inputs are input to a pre-dictive model (34) that operates in conjunction with an inverse model (36) to generate predicted control inputs. The predicted control in-puts are processed through a filter (46) to apply hard constraints, the values of which are received from a control parameter block (22). Dur-ing operation, predetermined crite-rion stored in the control parame-ter block (22) are utilized by a cost minimization block (42) to gener-ate an error control signal which is minimized by the inverse model (36) to generate the control signals. The system works in two modes, an analyze mode and a runtime mode. In the analyze mode, the predictive model (34) and the inverse model (36) are connected to either training data or simulated data from the analyzer (30) and the operation of the plant (10) evaluated.  The values of the hard constraints in filter (46) and the criterion utilized for the cost minimization (42) can then be varied to change the constraints on the control signals input to the control network, the predicted output of the predictive model (34) and the hard constraints stored in the filter (46). Cost coefficients can be utilized as the criterion to set the input values in accordance with predetermined cost constraints.

Patent CA-2175422-A1 (CA)
Inventor: BRANDAUER EDGAR
IPC: C08J9/00
Filed: 1996-04-30
Abstract: A process produces foam bodies having various properties and containing cellulose-containing materials broken up and/or partially broken up and/or not broken up, and additives, if need be.  The cellulose-containing starting materials are first processed further for forming a moist pulp and subsequently subjected to a heat treatment by microwave radiation.  The properties of the foam bodies so produced are predetermined by admixing certain substances intensifying the formation of gas in the pulp, increasing the adhesive bond between the particles in the pulp, or which completely or partially convert into a gas either under the influence of heat or of moisture, thus supporting the foaming.  Furthermore, other residual and waste materials can be added during the production process, which may be materials of a silicate nature as well, preferably with the objective of reusing such materials in a useful way and of predetermining at the same time certain product properties of the foam bodies.
