Patent CA-2116594-A1 (CA)
Inventor: CATUDAL MARCEL
IPC: B24B9/04
Filed: 1994-02-28
Abstract: Toutes les personnes qui pratique le patinage connaissent les bienfaits d'une lame de patin avec de bons tranchants Depuis 1983, il existait une façon d'éliminer en partie la friction naturelle qui existe entre la lame de patin et la glace qui consistait à polir le centre d'une lame tout en modifiant le rayon de coupe initial. Le produit de cette invention démontre que l'on peut perfectionner le tranchant tout en gardant le même rayon de coupe initial et ainsi réduire la friction sur une plus large surface. BUT DE L'INVENTION Voici une liste énumérant les objectifs de cette invention: - perfectionner un aiguisage conventionnel et de réduire la friction entre la lame et la glace; - parfaire le tranchant et l'uniformité de la lame tout en gardant le rayon de coupe choisi; - réduire la friction de la lame sur la glace en lui donnant un tranchant plus parfait.

Title: Method of reprocessing residual metallurgical materials which contain zinc and lead
Inventor: BRESSER WOLFGANG
IPC: C22B13/02
Filed: 1994-05-11
Abstract: ABSTRACT      Residual metallurgical materials which contain zinc and lead are reprocessed by a ther-mal treatment in a circulating fluidized bed. The required heat is generated in that solid carbon is combusted in the fluidized bed reactor of the circu-lating fluidized bed. A solid carbon content of 5 to 30 % is maintained in the lower part of the fluidized bed. Oxygen-containing gases are supplied to the upper part of the fluidized bed reactor, and CO2 is formed only in such an amount that zinc metal will not be re-oxidized. Substantially all solids are removed from the discharged suspension in a recycle cyclone and are recycled. The gas is cooled to a temperature at which zinc metal is oxidized to ZnO. The dustlike compounds of zinc and lead are separated from the gas.

Title: Stable automatically-engageable jackable prop
Inventor: BOULANGER DAVID M
IPC: B66F7/00
Filed: 1994-06-30
Abstract: A novel jackable prop or stand is provided herein.  It includes a base including a transverse plate and a pair of widely spaced-apart, forwardly-projecting feet.  A pair of spaced-apart,  perforated  posts,"I"-shaped  cross-section upstand from the base, each such post having a plurality of vertically-spaced-apart  apertures  through the  web.    A freely-vertically-movable riser assembly is slidably, but not relatively rotatably-mounted on the posts.  The riser assembly include a pair of bushings, each having an "I"-shaped cross-section complementary to the posts, and a pair of   forwardly-projecting,   load-bearing lifting   arms operatively associated with the transverse bar at the vicinity of the bushings.  A spring-biased pin is adapted to be manually manipulated to allow automatic removal from and entry into, the next vertically-higher aperture in the associated web to hold the riser assembly in a raised position and to allow locking of the pin in an associated aperture in the web.  That pin is adapted to be manually rotated through 180° to permit the pin to be urged out of the apertures to lower the load.   Engagement plates are provided on the base and on the transverse bar to be engaged by a jack.  Operation of the jack causes the riser assembly and hence the transverse bar and the load bearing lifting arms,  to be raised against a  load and to be automatically held there.   The  riser assembly  can  be lowered by rotating the spring-loaded pins.

Patent CA-2131925-A1 (CA)
Inventor: SALCER WILLIAM
IPC: A63B67/14
Filed: 1994-09-09
Abstract: The hockey puck has a main body portion with opposite parallel surfaces.  Ground engaging runners project from each of the opposite base portions of the puck and thus elevate the base surfaces of the puck from the ground to minimize surface contact between the puck and the ground.          The ground engaging projections are equally spaced in a circular array at a rim portion of the puck.  Openings in the puck concentrate weight at the center and periphery of the puck.  The ground engaging projections and the main body portion are formed of different plastic materials, with each plastic selected for the most desirable physical properties and performance characteristics.  Thus the ground engaging runners are relatively wear resistant with low ground friction whereas the main body portion is of relatively low hardness and provides the requisite stability and weight to the puck.  The puck is formed as a composite of an inner spider mold that forms the ground engaging projections and an overmolded portion that constitutes the main body.

Title: Queue managing system and method
Inventor: KAMINSKY MARK E
IPC: H04Q3/545
Filed: 1994-01-24
Abstract: In a queue management system for servicing of a number of clients representing different client types, a controlling queue queues clients in a predetermined order. A queue manager allocates and reallocates a number of processing queues, less than the number of client types, to match different one of said client types. The queue manager then places successive ones of the clients in the controlling queue into a processing queue matching the client type if there is a matching processing queue and allocates or reallocates an empty or emptied processing queue to the client type if there is no matching processing queue but there is an empty processing queue. A server empties the processing queues in batches. In the environment of a telephone system the clients are messages and the client types are codings in the messages for various destinations.  The queue manager dedicates each of a number of processing queues to one of the destinations in the controlling queue, accesses the top message in the controlling queue, places the messages in a processing queue matching the destination code of the message if there is a match, and dedicates an empty processing queue to the target destination if there is no matching processing queue but there is an empty processing queue.

Title: Method and apparatus for the measurement of sulfur compounds in process or transmission streams
Inventor: KIRK DAVID
IPC: G01N21/76
Filed: 1995-11-08
Abstract: A sulfur specific detection system, based on flameless sulfur chemiluminescence,which can determine the concentration of the sulfur component of complex matrices in a real time process application is disclosed herein. The system is comprised of a flameless reaction furnace, a chemiluminescence chamber and an electronic control system to control the flow of gases within the system and to provide analyses output in human readable form. The reaction furnace is an externally heated combustion zone that contains two pre-conditioned ceramic tubes. The tubes are of different sizes and are configured such that the smaller tube is a telescoping fit within the larger tube. Air and effluent from a chromatograph column are mixed at one end of the larger tube while hydrogen flows into the smaller tube counter current to the air and effluent. The system is under substantially 29 inches Hg at all times. The atmosphere in the ceramic tube assembly combined with the near vacuum conditions allows for the for-mation of sulfur monoxide when a sulfur containing compound passes through it. The sulfur monoxide along with the products of combustion, are drawn under vacuum tothe chemiluminescence chamber where ozone is continuously added. Ozone and sulfur monoxide react to form an electronically excited form of sulfur dioxide which releases ultraviolet radiation upon relaxation. The light released from the reaction is detected by a photomultiplier tube assembly and is linearly proportional to the amount of sulfur present. By eliminating upstream chromatography and injecting the sample directly into the reaction furnace, total sulfur concentration measurements made be obtained.
