Patent CA-2253258-A1 (CA)
Inventor: BUCHAN ROBERT MYLES
IPC: E02F9/22
Filed: 1997-04-09
Abstract: A snubber (60) is used to damp the swing of the door (36) on an excavator bucket (30) to prevent the door (36) from being damaged by repeatedly slamming shut.      The snubber (60) has a housing (61) which mounts to an excavator bucket and a shaft (70) pivotally mounted in the housing and connected to an excavator door (36). The shaft (70) turns when the excavator door (36) opens. The housing (61) has a cylindrical cavity (72) around the shaft. The cavity (72) is divided into two volumes (72B, 72A) by a dam (82) and a wiper arm (80) on the shaft (70). The wiper arm (80) forces hydraulic fluid (94) to flow through an orifice (101) between the volumes (72B, 72A) as the shaft (70) turns.      The wiper arm (80) has end seals (90) which seal against end walls (68, 66) of the cavity (72). The end seals (90) are forced outwardly by hydraulic pressure when the door (36) is closing. A one-way valve (102) allows hydraulic fluid (94) to bypass the orifice (101) while the door (36) is opening.      The snubber (60) requires less maintenance than previous friction-type snubbers.

Title: Insolubilizing additives for paper coating binders and paper surface sizes
Inventor: HUDSON ALICE P
IPC: D21H19/58
Filed: 1998-11-17
Abstract: Insolubilizing agents are disclosed for pigment binders and surface sizes containing functional groups capable of reacting with carboxylic acid anhydride moieties to form chemical bonds. The insolubilizing agents are polymers or other compounds containing a plurality of carboxylic acid anhydride moieties per molecular entity. The anhydride moieties do not substantially hydrolyze or otherwise react until the paper coating is applied to the paper and dried and cured, at which time the anhydride moieties react with the functional groups of the pigment binder or surface size and render it water insoluble. A method to improve the water resistance and printability of coated paper using the insolubilizing agents of the invention is also disclosed.

Filed: 1999-02-03
Abstract: A mechanism for locking an access door of an appliance includes a spring biased catch member preferably attached to the door and a latching housing insert fixed to a cabinet shell of the appliance. Upon closing the door, the catch member is caused to ride up a ramped retaining element mounted in a latching cavity, while simultaneously pivoting a first locking element between release and set positions. When the door is fully closed, the catch member drops behind the retaining element to releasably hold the door closed.      When it is desired to maintain the door in a securely locked position, a linear actuator is activated to shift a second locking element into engagement with the first locking element. Preferably, the first and second locking elements are engaged through a ratchet connection which enables continued rotation of the first locking element to only further lock the catch member in the latching cavity. Deactivation of the linear actuator enables opening of the door, preferably in a timed and controlled manner in accordance with a safety unlocking algorithm.

Title: Reusable electrosurgical return pad
Inventor: FLEENOR RICHARD P
IPC: A61G13/00
Filed: 1997-10-14
Abstract: This invention is a reusable electrosurgical return electrode pad (20) for use with electrosurgery.  In one embodiment it includes a presentation or working surface area lying in a range of from about 11 squares inches to 1,500 square inches. In another the working surface is at least as large as that of a projection of about half of the profile of the trunk of a patient. In yet another, it includes a working surface area at least as large as that of a projection of the profile of both the trunk and legs of a patient. It is adapted for disposition on the working surface of an operating table (40) or dentist's chair (50) immediately underlying a patient during electrosurgery.  By presenting a very large working surface area, the need for direct contact or contact through conducting jells is eliminated. Through employment of washable surface areas, it is made readily cleanable and reusable. Through the selection of resistance characteristics for the electrode materials of the principal body of the electrode, and through tailoring of electrode geometries, it is made self-limiting as to- current density and temperature rise so as to prevent patient trauma. An optional sleeve is provided for cooperative use with the electrode.

Title: Error correction decoder for vocoding system
Inventor: TOY RAYMOND L
IPC: G10L19/087
Filed: 1997-12-15
Abstract: An error control decoder receives a received vector to be decoded. The decoder then calculates, as an error estimate, the Euclidean distances between a codeword choice and the received vector. The output error estimate is appropriately scaled and quantized in accordance with the particular code being processed by the decoder. The efficient Conway-Sloane algorithm is extended for use in connection with the decoding of shortened Golay codes. A  modification is made to the generator matrix for the Golay code to produce a modified generator matrix that is unique for each shortened code. The modified generator matrix is then implemented in the Conway-Sloane algorithm to identify the best codeword for the conversion to its corresponding information bits for output. For improved multi-band excitation vocoding system.

Abstract: In order to reduce the duration for establishing verification protocols during the connection of a chip card to a reader, to reduce the risks of corruption during this operation and to limit memory occupancy, it is proposed to constitute a signature which can be used for verifying the adequacy of the chip card for implementing an application. This signature is carried out by a signature machine which prepares a concatenated word including all the data required for producing this signature. Thus it is possible to modify on request the structure of the required signature for an application without having to modify the operational system of the memory chip.

Inventor: SAFAR JIRI G
IPC: A61P25/28
Filed: 1998-02-20
Abstract: An assay method is disclosed which makes it possible to determine the presence of a diseased related conformation of a protein (e.g., PrPSc or the .beta.-sheet form of .beta.A4) in a sample. A sample is divided into two portions and the first portion is cross-linked to a first solid support and then contacted with a labeled antibody which binds to a non-disease form of the protein with a higher degree of affinity (e.g., 4 to 30 fold higher) than to the disease form of the protein to change conformation to a form with a higher binding affinity for the labeled antibody. The treated second portion is then bound to a second solid support and contacted with labeled antibody. The level of labeled antibody binding to a protein in the first and second portions is determined and the amounts measured in each are compared. The difference between the two measurements is an indication of whether the disease related conformation of the protein was present in the sample. The method can also determine the concentration of the disease related conformation and the particular strain present.
