Patent CA-2114845-A1 (CA)
Title: Torque and/or rotational control apparatus
Inventor: HENNESSY DAVID R
IPC: F16D65/847
Filed: 1992-08-12
Abstract: A torque and/or rotational control apparatus is disclosed in a preferred form of a brake (10) including a plurality of pairs of actuators (18) positioned on opposite sides of a friction disc (16) by spacers (120) having tear shaped cross sections. The pads (32) of the actuators (18) are removably held by a slideable lock-ing pin (70) biased by a spring (80) into an aperture (68) of a backing plate (62) for the pad (32). A notch (64) formed in the pad (32) and the backing plate (62) is slideably received on a rail (66) axially extending from the housing (35) of the actuator (18) to prevent rotation about the locking pin (70). The friction disc (16) includes elongated and shortened fins (42, 43) upstanding between and equally circumferentially spaced intermediate first and second component discs (40, 41). The fins (42, 43) are free of circumferential interconnections to allow air to radially pass freely between the fins (42, 43). The elongated fins (42) extend generally tangentially from the inner edges of the component discs (40, 41). The spacers (120) are orientated with their lengths extending generally perpendicular to the fins (42, 43) and gen-erally parallel to the air movement from between the component discs (40, 41). The shape and orientatin of the spacers (120) pro-mote laminar flow and reduce air turbulence to increase air flow around the spacers (120) and through the friction disc (16) and the brake (10).

Title: Adaptor cap for trocar assembly
Inventor: STEPHENS RANDY R
IPC: A61B17/34
Filed: 1994-03-07
Abstract: ABSTRACT   An adaptor cap assembly is provided for a trocar, consisting of a base which contains an opening which is the same size as the opening of the trocar cannula handle. There is also a cap integrally attached to the base which contains a gasketing assembly wherein the assembly is of a smaller diameter than the diameter of the trocar cannula handle opening as well as the opening in the base of the adaptor cap assembly.  This cap is hingedly attached to the base so that it can be flipped by using the thumb either into or out of alignment with the openings of the trocar cannula handle and the base of the adaptor cap assembly.   Thus, this mechanism can be used so that a smaller diameter instrument can be placed within a larger diameter opening (with the adaptor cap in place), or, the adaptor cap can be moved out of place so that a larger diameter mechanism can be inserted within the adaptor cap assembly and into the trocar cannula handle, with both the base and the trocar cannula handle having the same size opening.

Patent CA-2120897-A1 (CA)
Inventor: SANO HIROAKI
IPC: H02G1/08
Filed: 1994-04-08
Abstract: A method and an apparatus are provided for inserting and removing a communication wire, in and out of a pipeline by air flow, in which static electricity can be prevented from being generated, and a long communication wire can be inserted and removed.  The communication wire is fed from a reel, and inserted into a pipeline through a blowing head.   Compressed air is also sent from a compressor to the pipeline through the blowing head.  A drop cylinder is attached to a T-branch on the way of the pipeline, conductive material stored therein is supplied into the pipeline at a controlled rate.  A recovery bottle is attached to the outlet side of the pipeline so that the air flow blowing out of the outlet side is passed through a filter 11, and at the same time the conductive material is recovered.  By making the conductive material pass through the pipeline  together  with  the  air  flow,  generated  static electricity can be eliminated, and the communication wire can be prevented from contacting tightly with the pipeline because of the static electricity.
Patent CA-2122132-A1 (CA)
Title: Anti-sense oligonucleotides for isotype-specific suppression of immunoglobulin production
Inventor: CHANG TSE WEN
IPC: C07H21/04
Filed: 1992-11-18
Abstract: The invention includes oligonucleotides which are complementary to the 3'-end untranslated regions or to at least some of the splicing recognition region of an mRNA transcript precursor for a particular immunoglobulin heavy chain. More particularly, the oligonucleotides are complementary to at least a continuous 12 nucleotide segment of the sequence upstream to the 3' splice junction up to and including the branch point A residue. Sequences of some of the oligonucleotides of the invention are the underlined portions of SEQ ID NOS: 3-33. These oligonucleotides will hybridize with the splicing recognition region and prevent or inhibit maturation of the mRNA. This will prevent production of mRNA encoding a complete immunoglobulin, so that it will not be translated into a functional immunoglobulin. The invention also pertains to the preparation of these anti-sense oligonucleotides for specifically suppressing IgG and/or IgM production in patients suffering from autoimmune diseases and for specifically suppressing IgE in patients suffering from allergic diseases manifested by immediate-type hypersensitivities.

Abstract: The coin sorter includes a rotating hard disc (12) forming the bottom of a hopper (10) and a stationary sorter plate (20) to one side of the hard disc. The sorter plate includes a circular sortint track that begins at a point adjacent to the perimeter of the hard disc and which includes a series of spaced sorting openings (31a, 31b, 31c, 31d, 31e and 31f) each sized for a particular coin denomination. The track has an edge defined by a thin resilient rail held in place in a groove by an elastomer band. A second rotating disc (25) having a series of resilient fingers (27) depending from its underside is mounted above and in close proximity to the upper surface of the sorter plate. The fingers partially overlap the upper surface of the hard disc. Coins deposited in the hopper are formed into a single file and single layer at the outer edge of a central upright portion (16) of the hard disc. The single file of coins is carried by the flexible fingers from the hard disk to the sorting track where the coins are sorted by size and counted as they pass through the sorting openings.

Patent CA-2147013-A1 (CA)
Inventor: LANKFORD DOUGLAS EDWARD
IPC: H04N7/52
Filed: 1995-04-13
Abstract: A compressed audio/video, A/V, receiver provides A/V component timing reference signals (PTS's) coincident with reproduction of associated decompressed component signals. Synchronization apparatus generates a function of the difference of occurring component audio and video PTS's. This function, which is indicative of relative audio and video synchronization, is compared with a predetermined threshold value, and a mute control signal is generated when the threshold is exceeded. Muting circuitry, responsive to the control signal disables audio reproduction when the reproduced audio and video component signal timing deviate from mutual synchronization.
