Patent CA-2124871-A1 (CA)
Title: Universal Joint for Torque Transmitting Tools
Inventor: ROBERTS PETER M
IPC: B25B23/00
Filed: 1994-06-01
Abstract: A socket wrench universal joint includes a socket engaging element movably mounted in the drive stud of the universal joint to engage a socket.  An actuator is mounted to the universal joint for manipulation by a user, and a linking element links the actuator and the socket engaging element.  The actuator allows the user to alter the socket retaining forces. In a quick release version the operator can release a socket from the drive stud of the universal joint by appropriately manipulating the actuator.  In another version the user can enhance socket retaining forces by properly manipulating the actuator.

Title: Cylindrical waveguide resonator filter section having increased bandwidth
Inventor: GRAY DEVON J
IPC: H01P7/06
Filed: 1994-10-26
Abstract: A high Q microwave filter.   Coupling bar structures are included in a cylindrical resonator, extending substan-tially the entire length of the resonator for coupling orthogonal modes.  The coupling bars have a lower profile than conventional tuning screws.   The symmetry of the filter structure is improved over the prior art coupling devices which relied entirely on tuning screws for coupling E fields of one mode to the other mode.  The coupling bar structure has a lower profile penetrating less into the supported E fields while obtaining the desired coupling. Increased bandwidth may be obtained at improved symmetries over the prior art devices.  Fine tuning may be provided by inserting tuning screws into the cylindrical cavity.  The tuning screws require less penetration as substantially most of the coupling occurs by virtue of the coupling bars.
Patent CA-2135046-A1 (CA)
Inventor: WINTERS JOHN R
IPC: C01B11/02
Filed: 1994-11-03
Abstract: A plug flow process for the production of chlorine dioxide by reacting  chloric acid and/or  an alkali metal  chlorate, optionally a mineral acid and a reducing agent in such propor-tions that chlorine dioxide is produced.  Reactants are continu-ously fed to a plug flow reactor under conditions that chloride dioxide is produced as the reactants flow through the reactor.          The process stream has an acidity between 2N and 11N.   The process stream is subjected to superatmospheric pressure in the reactor sufficient to maintain the formed chlorine dioxide in solution.  After removal of the chlorine dioxide from the process stream exiting the plug flow reactor, the process stream can optionally be fed to a second chlorine dioxide generator for further reaction.

Title: Method of making moisture resistant aluminum nitride powder and powder produced thereby
Inventor: HOWARD KEVIN E
IPC: C04B41/45
Filed: 1993-01-28
Abstract: A method for making a moisture-resistant aluminum nitride-containing powder which includes (a) coating a layer of silicate onto alulminum nitride-containing powder having aluminum nitride on at least a portion of its surface and (b) heat-treating the coated aluminum nitride-containing powder at a temperature of from 350 to 1000 °C for a period of time sufficient to cause the silicate to react with the surface aluminum nitride thereby forming a layer of Si-Al-O-N bonded to the surface aluminum nitride. The silicate has alkyl or alkoxyalkyl radicals attached thereto. The method yields a moisture-resistant aluminum nitride-containing powder having a layer of Si-Al-O-N reaction-bonded to the surface aluminum nitride.

Title: Step up platform with folding hand rail
Inventor: SHORROCK LARRY J
IPC: A47C12/00
Filed: 1995-08-15
Abstract: The present invention relates to a step up device which provides a large stable platform with a hand rail to give the user a safe method of elevation. Older and/or infirm people frequently experience limited movement of their limbs making it difficult to get into bed.  To do this an elevation aid is often required. Current stools and step up devices for this purpose are widely available in hospitals but are cumbersome taking up much storage space and are difficult to transport from place to place for use by different patients. This invention provides an improved step-up device which reduces storage space and improves transportation.  The present invention provides a large stable platform with a hand rail to provide the user with a safe method of elevation. The hand rail is foldable, and is positioned to provide stability to the platform. The top of the platform is designed with a non-slip surface and a non-skid material is fastened to the legs to provide further stability.  Rolling means may be provided to aid in ease of movement of the step up platform. The rolling means are installed in such a manner that the platform must be tilted upon one edge for the rolling means to be able to engage the supporting surface thus preventing the device from accidentally rolling while in use.
