Abstract: A support block for supporting and interconnecting multiple electrical connectors to form a "two-fer" electrical circuit splitter includes a first portion with a first thickness forming a first surface for holding a male electrical plug and a second portion of a second thickness extending from the first portion and forming a second and a third surface for holding respective ones of a pair of female electrical plugs. An aperture is formed in the second portion and extends from the second to the third surface to allow electrical connections to be made between the pair of female plugs. Secure electrical connections can thus be made via cable passages of the male and the female plug, as well as between the two female plugs through the aperture positioned therebetween. A projection is formed on the block near the third surface which projection fits within and substantially covers the cable passage in the second female plug.

Patent CA-2227271-C (CA)
Title: Multiple level minimum logic network
Inventor: REED COKE S
IPC: H04L12/56
Filed: 1996-07-19
Granted: 2002-12-31
Abstract: A network or interconnect structure utilizes a data flow technique that is based on timing and positioning of messages communicating through the interconnect structure. Switching control is distributed throughout multiple  nodes in the structure so that a supervisory controller providing a global control function and complex logic structures are avoided. The interconnect structure operates as a "deflection" or "hot potato" system in which processing and storage overhead at each node is minimized. Elimination of a global controller and buffering at the nodes greatly reduces the amount of control and logic structures in the interconnect structure, simplifying overall control components and network interconnect components and improving  speed performance of message communication.

Abstract: A grain processing apparatus is used in one embodiment for debranning grain to remove the bran. In another embodiment, it is used as a mill for milling flour. The processor includes a cylindrical drum with an internal rotor having a set of impeller rods. The grain is loaded into the drum and is withdrawn as debranned kernels or flour as treatment proceeds. Bran removed from the grain is withdrawn through a vacuum discharge at the top of the apparatus. The grain is either discharged through a grain discharge or, where it is to be milled, it is withdrawn through the vacuum discharge as flour. The relatively coarse bran can be separated from the flour using a sifter. The air flow withdrawing the flour from the drum is drawn into the drum at the bottom, through a venturi and a valving arrangement. This cools the inlet air and maintains the temperature of the drum at an acceptable temperature.

Inventor: KIMURA YASUYUKI
IPC: G11B27/10
Filed: 1997-11-10
Granted: 2001-05-15
Abstract: A data recording method and device for an optical memory card which is adapted to prevent a recording error due to step-out during a data recording operation, and minimize a decrease in the recording capacity of an optical memory card.      While data are recorded, an output from an SYNC mark detection circuit (2) and an output from an internal synchronization signal generation circuit (3) are compared with each other in a comparator circuit (4). When step-out occurs, a write signal generation circuit (5) is stopped and the data recording operation is interrupted, and a re-recording operation is started at a frame adjacent to the frame in which a recording error occurred, on the basis of the value in a write cycle counter, whereby a decrease in the recording capacity of the optical memory card is minimized.

Abstract: An angular compensation hinge for a human joint brace, as well as the brace into which the hinge is incorporated, are described herein. The angular compensation device includes an angular compensation device comprising: an annular compensation hinge comprising a hinge pin and a pair of leaves pivotable thereon; a bar moveably attached at its ends to said leaves; and a rotatable screw threadedly engaged with said hinge pin and said bar; wherein rotation of said screw causes said hinge leaves to pivot on said hinge pin;  such that, when said pair of leaves are attached respectively to adjacent halves of a human joint brace, rotation of said screw and pivoting of said leaves causes angular adjustment between said halves respective to each other. The hinge may be used with many different types of braces, including those intended for knee, wrist, elbow, ankle, hip and shoulder joints. It is of particular utility with braces intended to relieve osteoarthritis pain, especially for those braces in which an adjustable condyle pad is used to provide the pain - and pressure-relieving force against the joint.
