Patent CA-2083517-A1 (CA)
Inventor: MAYNE ALFRED R
IPC: F04B1/04
Filed: 1991-05-22
Abstract: A machine that converts between reciprocating motion of a piston (21) and rotary motion of a shaft (26). The shaft (26) rotates an integral web (25) that carries a number of lobe wheels (23) spaced evenly about a pitch circle centered on the shaft (26). The lobe wheels (23) are planetary driven by pinions (27) and a fixed ring gear (34). The lobe wheels (23) are somewhat star shaped with radially extending lobes which push followers (32) outwardly, then release them inwardly, as the lobe wheels (23) orbit past and below the follower (32). The follower (32) is connected by a lever (22) and a pair of connecting rods (36 and 37) to the piston (21).

Title: Two stroke engine with modified transfer passage configuration
Inventor: BOYCE MARIO
IPC: F02B75/02
Filed: 1993-01-13
Abstract: ABSTRACT:          A two stroke engine which increases the volume of air which is adapted to flow through the transfer passages. The engine has a configuration whereby the inlet and outlet ports are superposed at the front of the block thus freeing valuable space at the rear of the block. The space at the rear of the block is used to add a supplementary transfer passage.    To further optimize the efficiency of the engine, the engine has a modified piston head adapted, when in its lowermost position, to seal-off  the entry ports  while leaving  open  the apertures leading to the entry of the transfer passages.   The transfer passages always being unobstructed, the flow of the gases is always unrestrained during their passage from a position underneath the piston to a position inside the combustion chamber.    Secondary features include the use of a base surface at the bottom end of the cylinder and of an upstanding block extending integrally from the base surface to minimize turbulence of the flow of gases and thus to further increase the efficiency of the engine.

Patent CA-2094026-A1 (CA)
Inventor: WEISS KENETH P
IPC: G06F21/35
Filed: 1991-04-30
Abstract: A method and apparatus for providing improved security for a personal identification number (PIN) in a personal ident-ification and verification system of the type wherein a time de-pendent nonpredictable code is generated at a device in the pos-session of the individual (36), which code is unique to the indi-vidual and this code is communicated to, and compared with a nonpredictable code generated at a central verification compu-ter (46). In this system, the PIN is mixed with the nonpredic-table code before transmission of these values to the central ver-ification computer (38). A nonsecret code (30) is previously transmitted to the central verification computer and is used by the verification computer to retrieve the PIN and independently generate the time dependent appropriate nonpredictable code for the user (74). These retrieved PIN and generated code va-lues are used by the verification computer either (a) to strip the PIN from the transmitted nonpredictable code (42) and the stripped PIN and remaining nonpredictable code are compared with the corresponding retrieved values in order to determine verification (44, 46); or (b) to be mixed and then compared with the mixed PIN and code which is transmitted to the verification computer (144).

Title: Method and apparatus for symmetrically modulating a controlled series compensation system
Inventor: LEOWALD KARL-FRIEDRICH
IPC: H02J3/18
Filed: 1993-05-14
Abstract: ABSTRACT OF THE DISCLOSURE   A method and an apparatus for symmetrically modulating a controlled series compensation system (2) in electrical networks (6). Impedance manipulated variables determined from a current control for the series compensators (14) of the system (2) are limited by determining an upper or lower limiting value (Zoo,Zou). The upper and lower limiting values are respectively determined by adding a positive or negative deviation (.DELTA.Z+, .DELTA.Z ) to and subtracting it from a reference manipulated variable (Zo) for impedance. The reference manipulated variable (Zo) for impedance is selected from the impedance manipulated variables (Zy1,Zy2,Zy3) Thus, small asymmetries can be corrected and, given network faults of generally only a brief duration, unnecessary control deviations can be avoided.

Title: Band-Clamping Apparatus
Inventor: HAM TAIRA
IPC: B23P19/08
Filed: 1993-06-09
Abstract: The present invention provides a band-clamping apparatus, which is capable of automatically clamping clamping bands wound. In the apparatus, a holding table holds a member to be clamped, which has been wound by the clamping band. A stopper prevents the clamping band on the member to be clamped, which has been held by the holding table, from moving, and the stopper is capable of contacting the holding pieces from the opposite side of a lever. A pushing arm turns the lever onto an outer face of a band section. A bending mechanism inwardly bends the holding pieces so as to secure the lever onto the outer face of the band section when the lever is located between the holding pieces. With the band-clamping apparatus of the present invention, manufacturing efficiency can be sharply raised, the clamping work can be executed safely, and the clamping strength can be maintain in the predetermined range.

Title: Prioritization between handoff and new call requests in a cellular communications system
Inventor: BODIN STIG R
IPC: H04W28/16
Filed: 1992-12-08
Abstract: A method and system for ensuring that handoff requests take priority over new cell requests to engage voice channels assigned to a particular target cell are provided. A certain number of channels are reserved for handoff requests. However, if no channels, reserved or unreserved, are available, handoff requests to a particular target cell are stored in a corresponding queue for a predetermined period of time. Thus, when voice channels become available, they are seized in order to satisfy the handoff requests stored in that queue. If the handoff queue is empty, new call requests to a target cell may be assigned to available voice channels.

Abstract: A circuit and method for shortening the tran-sition time of sharp color transitions in color television signals.   The invention includes a pattern recognition circuit  and  method  which  directly  and  efficiently recognizes color transitions within a predetermined range. The disclosed embodiment of the invention utilizes a filter to output its step response to the pattern recognition circuit which outputs a control signal whenever the color signal rise or fall time does not fit a predetermined pattern.  When the pattern recognition circuit recognizes the step response, it directs a hold circuit to output a previous  color  signal  for a predetermined time period before allowing the transition to proceed, thus shortening the transition time.

Title: Pipeline padding apparatus with rotary feeder
Inventor: OSADCHUK MARK
IPC: B07B1/00
Filed: 1994-04-25
Abstract: An improved pipeline padding apparatus includes a separator for separating fine material out of spoil which is piled along side an excavation, an elevator for transporting spoil to the separator, and a pair of spaced-apart guide projections for guiding spoil into the elevator. The spaced-apart guide projections form a substantially open bottom extending the width of the elevator between the guide projections. A conveyor is provided to transport the separated fine portion of the spoil back into the excavation, thereby padding the pipeline.  The separator, the elevator, the guide projections, and the vehicle are all mounted on a support vehicle. According to one aspect of the invention, one or more rotary feeder assemblies is mounted to the guide projections for assisting in moving spoil through toward the elevator. The rotary feeder assemblies have a low profile so that spoil material and rocks do not become stuck as they move toward the elevator. In another aspect of the invention, the motor of the tracked support vehicle is mounted above and forward of the elevator, which helps reduce the amount of dust that the motor is exposed to during operation. According to another aspect of the invention, the guide projections may be configured to allow excess spoil to flow underneath in such a manner as to smooth out a path for the tracks of the support vehicle.
