Patent CA-2057797-A1 (CA)
Inventor: EDWARDS LARRY M
IPC: H02J9/06
Filed: 1991-12-17
Abstract: A fail safe power supply system specially adapted for supplying power to devices such as lights. A battery is provided to supply power to the devices, and during normal operation, charge on the battery is maintained within selected levels by a charging control system that is connected to a source of commercial power. During a commercial power outage, the battery continues to supply normal power to the devices for a prolonged period of time, usually until commercial power is restored, thus obviating the necessity for a separate backup power source.

Patent CA-2063255-A1 (CA)
Inventor: DICK JOHN G
IPC: A63B23/04
Filed: 1990-07-03
Abstract: A self-actuated spring-action human bipedal device includes a back-mounted frame attached to the upper torso of a user, and separate articulated right and left leg frames pivotally attached by U-joints to lower portions of the back frame. The user's feet are secured to the leg frames so that the bottoms of the leg frames contact the ground, rather than the user's feet, behind the point where each foot is attached to its leg frame. A spring actuator is carried on the back frame, and endless cord-like main springs are engaged with the spring actuator. Left and right tension lines running from the left and right leg frames to the spring actuator are arranged so that compression of the leg frames, cause by the force of downward movement of the user's feet and torso, acting on the ground, pulls on the tension lines to apply a pulling force to the spring actuator for stretching the main springs. The tension lines are also each attached to a part of the leg frame which engages on the user's foot so that extension of the user's leg pulls on the tension lines, also stretching the main springs. The energy stored in the stretched main springs is then transferred back to the torso of the user and to the user's feet to cause the user to jump into the air by a distance above the ground approximately proportional to the amount of compression of the leg frame and the amount of stretch transferred to the main springs. Separate pick-up springs connected to each leg frame keep the tension lines under positive tension so that tension on each leg frame will not go slack and will apply a pick-up force to the leg frame to raise it and prevent foot dragging to simulate a natural walking gait.

Title: Saving time when reading data variables stored in a memory device and decreasing the load of a pointer device
Inventor: WILDING KLAUS
IPC: G06F12/00
Filed: 1992-10-28
Abstract: A B S T R A C T            A data processing system (3) generates successive individual numbers and write and read orders respectively for transmitting data variables from the data processing system to a memory device (1), and vice versa, via a variable register (9) in which data variables are temporarily stored. A pointer device (2) connected to the memory device converts the individual numbers to memory pointer values, so as to provide access to storage locations (10) indicated thereby, these storage locations being assigned to in-dividuals identified by the individual numbers.  For reading variables stored in the memory device, a time saving facility is obtained by providing the variable register with an activating input (18), and by including an intermediate register (13), a comparator (14),  a control signal generator (15)  and a stop circuit (7). A first individual number is temporarily stored in the intermediate register. The comparator compares the first in-dividual number with a second individual number obtained from the data processing system immediately after the first individual number. The control signal generator generates a control signal when the comparison shows equality and when the second individual number belongs to a read order. The stop circuit responds to the control signal, by stopping the calculation of the pointer value belonging to the second individual number. The activating input of the variable register responds to the control signal by activating transmission of the temporarily stored data variable to the data processing system.

Abstract: A heated injection molding nozzle (10) having a cylindrical locating flange (68) extending forwardly from a rear collar portion (52) to mount the nozzle in a well (66) in a cooled mold. The nozzle has a cylindrical central portion (54) with an insulative air space (74) extending between it and the surrounding cooled mold.
