Patent CA-2068881-A1 (CA)
Inventor: HUTCHINSON T GORDON
IPC: B42F3/00
Filed: 1991-09-16
Abstract: Dispositif d'attache (10) constitué de deux composants (15, 20) dont la fiabilité est liée à la déformation d'une ouverture de forme ovale-ellipsoïdale  (24).  Cette déformation résulte de l'insertion d'un goujon (15) dans l'ouverture (24) d'une douille (20).  La fixation et le dégagement des deux composants (15, 20) sont obtenus en resserrant les bords de la douille (20).  Il peut y avoir plusieurs disques d'inter-engagement (17) sur le goujon (15), et au moins un renfoncement (22) dans l'ouverture (24) de la douille (20) qui collabore avec un des disques (17).  Là où il y a plus d'un renfoncement (22) dans l'ouverture (24) de la douille (20), chaque renfoncement (22) s'engage dans un des disques (17) du goujon (15).  Il peut aussi y avoir deux composants de goujon (45A, 45B) pouvant être reliés de bout en bout au moyen d'une douille (40) adaptée pour s'engager dans chacun de ces composants (45A, 45B).

Title: Electrically conductive polymer thick film of improved wear characteristics and extended life
Inventor: BOSZE WAYNE P
IPC: H05K1/09
Filed: 1991-06-05
Abstract: An electrically conductive polymer film (10) composition comprises a polymeric resin, an electrically conductive substance intimately mixed in sufficient quantity with the polymeric resin to render the polymeric resin electrically conductive, and particles (16), such as fibers or spheres of appropriate size, admixed with the polymer composition in sufficient quantity so that in the cured polymer film the particles protrude from the surface (14) of the film and render the surface uneven on a micro scale. The cured polymer film composition of the invention is incorporated in potentiometers and similar electric and electronic devices as a thick film where a contact wiper (18) rides substantially continuously in contact with the protruding fibers. The potentiometers incorporating the thick layer polymer film of the invention have greatly extended useful life, generally extending for several million cycles of movement of the contact wiper on the film.

Abstract: Précis Dans la majorité des appareils nautiques à propultion humaine, l'opérateur est en position assise sur la flotteur et se déplace en actionnant des rames. D'autre véhicules sont propulsés par une hélice reliée à un pédalier; ces versions sont caractérisées par la position de l'opérateur qui est assis sur le flotteur actionnant le pédalier de bicyclette situé plus haut que la position de sas fesses. Dans la présente invention, le flotteur est aussi propulsé par une hélice reliée à un pédalier, mais il a la particularité d'être mu par un opérateur positionné à la manière d'un cycliste, c'est à dire les fesse au dessus du pédalier. Cette position permet à l'opérateur de remonter sur le flotteur s'il tombe en eau profonde, puisque le guidon et son support n'étant relié au pédalier que par le flotteur luimême, l'espace risiduel n'offre aucun obstacle à sa remontée, Enfin, l'opérateur peut utiliser son guidon pour se stabiliser une fois remonté sur le flotteur, puisqu'il est relié à un aileron dont la surface poussant sur l'eau offre un support suffisant pour contrebalancer les pertes d'équilibre de l'opérateur.

Patent CA-2094518-A1 (CA)
Inventor: GEMMER BRADLEY K
IPC: B07B11/06
Filed: 1993-04-21
Abstract: Apparatus and method are disclosed for separating and recovering the solid particle components of a waste aggregate using screening and air separation mechanisms.  Such an aggregate could be  log yard waste  comprising  soil,  wood and mineral particles.   The aggregate is first mechanically screened to produce a product of fine particles (the soil) and a plurality of sized streams, each comprised of similarly sized particles of different densities (the wood and mineral particles).  The sized streams are then separately but simultaneously introduced into an air separation device which comprises an upstanding funnel-like member forming an upwardly converging passage through which air is flowing.  The smallest sized stream of particles is fed into the passage at the lowest elevation, where a separation of light and heavier density particles occurs,  light particles moving upwards with the air, heavier falling downwards.  Medium and  larger  sized  streams  are  fed  at  respectively  higher elevations, where the air velocities are respectively higher, separation again occurring.   The inlet point for each stream entering the converging passage is selected to match the air velocity at that point with the desired separation result: heavier density particles to drop, lighter density particles to rise.  Two products are recovered from the funnel-like member, a  high  density product  (the  mineral  particles)  of  varying particle size from the base of the passage and a low density product (the wood particles) of varying particle size from the top.

Abstract: The present invention relates to a fusible switch for use in a multiphase circuit.  The switch includes an operating mechanism which is secured to the enclosure of the switch and provides for a handle to operate the opening and closing of switch contacts. Movement of the handle stores energy in the operating mechanism which is subsequently released in a quick motion just as the switch contact is to be opened or closed.  The switch also provides for heat sinks and means for venting the enclosure to dissipate the heat created from the higher voltage and greater current density carried by this improved switch.

Abstract: In a process for the recovery and re-use of raw materials from paper mill waste sludge, the sludge is subjected to a preliminary cleaning treatment at a relatively low consistency, thickened to a consistency of 10 to 30%, heated to at least 100°C and then passed through a dispenser in the thickened heated state before being passed. to a papermachine for re-use. Papermaking fibre from at least one other source is mixed with the sludge before and/or after treatment as just described, so that the final paper product typically contains up to 30% of raw materials recovered from sludge. The action of the dispenser is to break up dirt and other debris, and as a result, the recovered raw materials can be re-used in the manufacture of high quality fine papers.

Title: Mixed resolution, n-dimensional object space
Inventor: ESTES MARK D
IPC: G06F13/00
Filed: 1992-01-07
Abstract: Object spaces which mechanize higher order relationships between attributes which describe a particular problem domain. An abstract object description defined by a set of attributes and their corresponding values is transformed into a mixed-resolution, N-dimensional object space. The mixed-resolution, N-dimensional object space represents a mechanized, logically encoded expression of attribute relationships that can be visualized. The method and apparatus interleave the frame to generate an object descriptor and generate from the frame and the object descriptor, encoded names of spatial locations for each of the N dimensions of the mixed-resolution, N-dimensional, object space, conforming to a primary form of a reflected binary code. A virtual image of the N-dimensional, object space is generated from the dimensional-spatial locations and resolution-spatial locations, and attribute values corresponding to a region of the virtual image may be selected for display.

Abstract: A series of hard disk drives are secured atop molded plastic support trays slidably and removably received in opposing guide channel member pairs snap-fitted into opposite side walls of a sheet metal cage structure externally used in conjunction with a file server or other computer device. Snap-fitted into rear end portions of the trays are small printed circuit boards that are insertable into hot plug sockets at the rear of the cage. Forwardly projecting guard plates on the rear end of the cage block manual access to the board/socket interface, and the surface mounted grounding leads on the board extend rearwardly beyond its signal leads to enhance grounding safety during disk drive installation and removal. At the front end of each tray is a vertical support plate upon which LED indicating lights are conveniently mounted for the associated disk drive. Each guide channel member has a metal grounding clip portion that is pressed against the adjacent cage wall and is contacted by a grounding screw on the disk drive as the drive is slid into the housing, the grounding screw also functioning to prevent inadvertent upside-down installation of the drive. To assist in installing and removing each disk drive, its associated support tray is provided at its front corners with pivotable ejection latch members removably secured thereto using a molded connection structure that eliminates the requirement for attachment screws or rivets.
