Patent CA-2155331-A1 (CA)
Inventor: MOORE JOHN WESTWOOD
IPC: F16H48/12
Filed: 1994-02-11
Abstract: A differential drive mechanism comprises a cage (8), which is rotatable about an axis (6) and represents the input, two coaxial output shafts (2,4) which are rotatable with respect to the cage (8) about the said axis (6), a coupling (16) which is connected eccentrically to the two output shafts (2,4) to transmit relative contra-rotational movement between them by connections which permit relative rotation of the coupling (16) and the output shafts (2,4) about an axis (14) substantially parallel to the said axis (6) and a restraint member (20) which is coupled to the cage (8) and to the coupling (16) such that the coupling (16) is rotatable with respect to the cage (8) about an axis substantially perpendicular to the said axis (6) and capable of reciprocating movement in a direction perpendicular to the said axis (6) but prevented from movement in a direction parallel to the said axis (6). The eccentric connection of the coupling (16) and the output shafts (2,4) is constituted by a respective eccentric hole (12) in the inner end (10) of each output shaft (2,4) in which the associated end of the coupling (16) is received. The inner end (10) of each output shaft (2,4) is in sliding engagement with the inner surface of the cage (8) whereby as the cage (8) rotates about the said axis (6) the sliding surface on the inner end (10) of each output shaft (2,4) is pressed by the coupling (16) into contact with the opposing sliding surface on the cage (8) so that a proportion of the input torque transmitted to the cage (8) is transmitted directly to the output shafts (2,4) through the cooperating sliding surfaces and does not pass through the coupling (16) and restraint member (20). <IMAGE>

Patent CA-2180776-A1 (CA)
Inventor: CLOONAN THOMAS JAY
IPC: H04L12/56
Filed: 1996-07-09
Abstract: An out-of-band controller for a large packet switch which is distributed throughout partitions or pipes of the packet switch. Thus, the out-of-band controller is divided into multiple pipe controllers. These pipe controllers are connected andoperated in a ring such that each pipe controller is with a respective fraction of the input path requests for packets. The requests are processed concurrently and anyrequest that is not fulfilled in one pipe controller is offered to up to three subsequent pipe controllers to hunt a path for the awaiting packets. The controller, by using up to four levels of parallelism, can hunt paths and set up connections for 256 or more input ATM packet lines in normal monocast mode, thus providing a throughput of 1 terabit per second or more. A distributed controller design makes such tremendous aggregate switching speeds possible. The same general distributed controller design can also provide pipe hunting for a special packet operation called multicasting, in which one packet from one input line is transmitted to many or even all output lines. As can be appreciated, multicasting can monopolize system assets to the detriment of other ATM packets, so some multicasting may be made during special packet cycles when primarily multicasting packets will be carried. One such special packet cycle might occur at system initialization.

Title: Distributed lighting system with fiber optic controls
Inventor: HSU TSUNG-YUAN
IPC: G02B26/00
Filed: 1993-10-13
Abstract: A vehicle lighting system includes one or more central light sources (2a,2b), a plurality of optical loads (4R, 4L, 6R, 6L, 8R, 8L, 10R, 10L, 12 ,14) including headlight lenses (36), an optical fiber network (16R, 16L, 20, 24, 28R, 28L, 30R, 30L) that extends from the light sources to illuminate the headlight lenses and other optical loads, and optical switches (20, 32R, 32L, 34R, 34L) and oscillators ( 18R, 18L) that include respective input fibers (52a) illuminated from the light source and output fibers (52b) to respective op-tical loads, and operate by enabling and disabling optical connections between their input and output fibers . The headlight assemblies switch between high and low beams by moving their fibers vertically, and control beam diffusion by moving the fibers parallel to the lens axes, including an automatic diffusion adjustment for a headlight reflec-tion from a vehicle in front.  The switches include various mechanisms  for moving the input and output fibers into and out of alignment with each other, including a shaped resil-ient sleeve (54), a hinge (70) pivotally joining the fi-bers, an opaque shutter (82) with a transmissive section (86) movable between the fibers, and also a liquid-based switch (100) that relies upon total internal reflection. A feedback mechanism  (62,64,66) for some of the switches dims the source lamp when the switch is OFF to conserve energy.  The oscillators operate by normally urging an in-put fiber towards an OFF position, at which it actuates a mechanism  (114, 118, 124)  that shifts it to an ON position at which the  mechanism  is deactivated.  A failsafe system em-ploys multiple light sources (2a,2b), with each source sharing its light output with the load for another source that has failed.

Title: Refrigerant Powered Actuated Ball Valve
Inventor: MILLER KENT ALAN
IPC: F25B41/04
Filed: 1997-02-11
Abstract: A refrigerant powered actuated ball valve for use in the fluid circuit of a refrigeration or air conditioning system which can be remotely controlled by a low amperage control signal is disclosed.   The actuated ball valve harnesses the pressurized refrigerant from the fluid circuit in which it is installed as the primary power medium to actuate the valve.  The valve includes actuation means with a manifold having an inlet port which is in constant fluid communication with a high-pressure side of the fluid circuit.  Pressurized refrigerant supplied to the manifold is branched to a series of fluid channels running through the manifold.  Exhaust port operators are mounted in conjunction with the manifold to connect the actuation means to the low-pressure side of the fluid circuit and to direct the flow of pressurized refrigerant to either an exhaust port or the manifold.  A reciprocal member disposed within the manifold engages a pinion such that a linear displacement of the reciprocal member causes a corresponding angular displacement of the pinion member. Cycling of the ball valve between an opened position and a closed position is achieved when the pressurized refrigerant is applied to the reciprocal member thereby causing a stem operator on the ball valve to rotate.
