Patent CA-2042241-A1 (CA)
Inventor: CARSON STEVEN R
IPC: H02G3/14
Filed: 1991-05-09
Abstract: A  two-piece  face  plate  assembly  includes  a coupling plate which is mounted between the yoke strap of a wiring device and the mounting flange of a wall box.  The coupling plate has a central opening for receiving the wiring device and has first and second index pins disposed at spaced locations along the longitudinal axis of the coupling plate and in registration alignment with threaded mounting holes on the yoke strap.  The coupling plate also has press-fit connectors positioned symmetrically about the central opening.  The screwless face plate has a central opening for receiving the wiring device escutcheon and has a corresponding number of complementary press-fit connec-tors which are aligned for interlocking, press-fit engage-ment with the coupling plate connectors.  The wiring device is mounted onto the wall box by screw fasteners extending through mounting slot openings formed through the yoke strap and in engagement with threaded mounting holes on the wall box.  The index pins on the coupling plate project through the threaded retainer holes on the yoke strap, thereby maintaining horizontal and vertical alignment of the face plate with the wiring device.   In a multiple wiring device installation, a segmented coupling plate is expandable to accommodate two or more wiring devices.

Title: Torque limiter device and deployable lengthening piece of a space instrument equipped with this device
Inventor: VEZAIN GERARD
IPC: B64G1/22
Filed: 1991-05-15
Abstract: ABSTRACT OF THE DISCLOSURE So  as to  dampen the shock occuring at the  end of deploying  a  deployable lengthening  piece  of a  space instrument,   such   as  a   solar  generator,   without resorting  to   using  a  complex  speed  regulation  or synchronization  mechanism for  deployment, the  present invention  offers a  torque limiter  device (28a)  to be placed  between each joint (123 and at  least one of the adjacent  elements (10a) of the  lengthening piece. This device  includes an elastic  system, such as a  stack of Belleville  washers (48a) which presses  the plate (24a) of the  joint against the edge of the element (10a) with a predetermined  and preferably adjustable force. At the end  of  deployment,  this  elastic system  absorbs  the energy  of the  shock by deforming,  then it  brings the two pieces  (24a, 10a) back into contact with each other thus  giving  the  lengthening  piece with  the  desired rigidity.  An  accurate  relative  positioning  is  then ensured  by a flexible plate (34a) whose  lateral edges are secured to each of the pieces.            Fig. 2 SP 6159.69 GP

Title: Process for recovering oil from tar sands
Inventor: GREEN ROBERT C
IPC: C10G1/00
Filed: 1991-10-07
Abstract: A process for recovering oil from tar sands by subjecting the tar sands to aqueous extraction to produce a bitumen-rich layer containing bitumen, water and solids and a bitumen-lean layer containing rela-tively less bitumen and relatively more water and solids. The solids present in the bitumen-lean layer contain a substantial portion of finely divided clay having adhered organic matter. The clay solids are retained with the bitumen from the bitumen-lean layer and the bitumen-clay mixture is pyrolyzed. Pyrolysis of the bitumen-lean layer containing clay having adhered organic matter reduces the volume of aqueous tailings which would otherwise be produced and also results in increased hydrocarbon yields.

IPC: F04B27/14
Filed: 1991-11-08
Abstract: A slant plate type compressor having a capacity or displacement adjusting mechanism includes a housing for a cylinder block provided with a plurality of cylin-ders and a crank chamber.  A piston is slidably fitted within each of the cylinders and is reciprocated by a drive mechanism which includes a slant plate having a surface with an adjustable incline angle. The incline angle of the slant plate, and thus the capacity of the compressor, is controlled according to the pressure differential between the crank chamber and the suction chamber. The pressure in either the crank chamber or the suction chamber is controlled by an externally controlled valve mechanism which is disposed in a passageway linking the crank chamber and the suc-tion chamber. An internally controlled safety valve device prevents an abnormal pressure differential between the crank and suction chambers. The internally con-trolled safety valve device is provided within the externally controlled valve mecha-nism, thereby obtaining an easily manufactured slant plate type compressor having a capacity adjusting mechanism with a safety valve device.

Title: System for control of a lumber-drying plant
Inventor: SIEVERS JAN-HENRIK
IPC: F26B25/22
Filed: 1992-03-25
Abstract: (57) Abstract The invention concerns a method for control of the operation of a lumber-drying plant, in particular of a chamber dryer (10). In the method the tempera-ture (T) and the humidity (Rh) of the air passing through the lumber batch (K1,K2,K3) to be dried are controlled as the drying process makes progress. The progress of the drying process is regulated by means of a feedback-connected drying-formula simu-lator (23), by whose means the drying process is given new set values (S) continuously or at suitable intervals. Out of the drying process, measurement data (m) are passed to the drying-formula simulator (23), the drying process model stored in said simula-tor being adapted to the state of the drying process on the basis of said measurement data (m). In the method, an adaptive process model is applied, in which a certain parameter or certain parameters are allowed to remain variables, which is/are adapted in the correct direction on the basis of the measurement data (Rh,TK,u) received from the process.

Abstract: A method is provided for low pressure chemical deposition of tungsten and tungsten metallization for defining interconnects for an integrated circuit.  A surface layer of tungsten is provided which has a low film stress and a smooth surface characterized by a low diffuse reflectivity and high specular reflectivity, to facilitate photo-lithography.  Tungsten is deposited by reduction of WF6 with H2 and SiH4 in nitrogen.  Control of the gas flow rates, pressure, temperature and H2/WF6 ratio in the reactive gas mixture provides for tailoring of the structure and characteristics of a deposited tungsten layer to provide high step coverage or a smooth surface for forming an overlying layer of tungsten which may be patterned photo-lithographically for defining interconnect. In order to provide metallization providing both good step coverage in via and contact holes and smooth surface for deposition of surface metallization, a two-stage tungsten deposition is provided.

Title: Coupling assembly for corrugated decks
Inventor: CORNWALL KENNETH R
IPC: E03F5/04
Filed: 1993-02-26
Abstract: An improved coupling assembly (10) mounted on a  corrugated  deck  (30)  and  embedded  in  a  concrete partition, such as floor (100), to provide an opening through the deck and the floor,  is described.   The coupling is comprised of an inner conduit (13) mounted inside of an outer sleeve (11).  A flange portion (15) is provided at one end of the  sleeve and  includes openings  (19)  for fastening means,  such as nails or screws (21) that serve to secure the coupling assembly in position on the deck.  The conduit is mounted to the inside (11A) of the sleeve to position the opposed open ends (13B) and (13C) of the conduit extending beyond the sleeve means and through an opening (50) in the deck. The sleeve enables the contact point between the sleeve and the conduit to be adjusted along the length of the conduit.  This is useful in those situations where the conduit  has  been  mounted  in  an  existing  building construction or where the mounting position between the conduit and sleeve needs to be adjusted.  The coupling is then embedded in the poured concrete floor and fluid carrying pipes can be connected to the opposed open ends of the conduit.  The partition need not necessarily be a floor, but instead can comprise a wall.  The floor can also be sloped and an upper end of the conduit can be provided with a drain conduit (61) for removing liquid from the top of the sloped floor.
