Patent CA-2113724-A1 (CA)
Title: Radar reflectors
Inventor: RIX CLIFFORD
IPC: G01S7/02
Filed: 1992-07-27
Abstract: A radar reflector comprises a pair of opposed colinear solid dielectric lens reflectors (10) and two corner reflectors (11) be-tween to provide substantially uniform and high reflectivity in the plane of the reflector elements. Radar energy strikes the outer convex surface of a first converging lens element (12) of relatively high dielectric constant and is then transmitted through a sec-ond lens element (17) of material having a relatively lower dielectric constant to a reflecting metallic coating (18) on the outer con-vex surface of the second lens element (17). The surfaces of the two lens elements (13, 14, 18) are formed such that their respective radii of curvature decrease with distance from the axis of symmetry (15). The first lens (12) is preferably silica flour in a polyester resin with a dielectric constant substantially equal to 3.4 while the second lens element (17) is an expanded foam polystyrene with a dielectric constant substantially equal to 2. Preferably the corner reflectors (11) are trihedral reflectors.

Title: Banister and method of making the same
Inventor: GRECO FRANK
IPC: B23K31/02
Filed: 1994-07-20
Abstract: An aluminum banister includes a first run element, which acts as the bottom rail of the banister, defining two sets of apertures spatially disposed therealong, the first of said set being a first family of spatially disposed apertures interspaced between a second family of spatially disposed apertures, the second family being of larger cross-sectional area than the first so as to allow posts to extend therethrough which are in larger cross section than balusters which extend from the first family of apertures.  There is an upper run or top rail which has an upper portion of any configuration but a lower bottom section that, in cross section, defines two longitudinally oriented races, the wider outer race being a post accommodating race and the inner race being deeper and narrower mating with balusters.

Title: High performance head assembly for an internal combustion engine
Inventor: SMITH RICHARD W JR
IPC: F02B23/08
Filed: 1994-09-16
Abstract: A cylinder head assembly for an internal combustion engine. The cylinder head assembly has a deck surface for engaging an opposed deck surface on an engine block. A combustion chamber is recessed in the cylinder head assembly for each cylinder, and the combustion chambers each have first and second wedge portions. A first valve port penetrates the first wedge portion, and a valve seat is provided in the first valve port. The first valve seat is disposed at a first angle relative to the deck surface. A second valve port penetrates the second wedge portion, and a valve seat is provided in the second valve port.  The second valve seat is disposed at a second angle relative to the mounting surface. The second angle is less than the first angle. Each valve seat has a valve element for controlling the ingress and egress of gas flowing to and from the chamber.  The wedge portions permit a more erect valve orientation for the intake valve such that less scavenging of the fresh fuel/air charge will occur. The wedge portions also permit the exhaust valve and intake valve to moved to more advantageous locations relative to the combustion chamber. The relocation of the valves allows a more efficient placement of the spark plug, resulting in more even loading of the piston during the power stroke. The inlet passage which directs the fuel/air mixture to the combustion chamber has an independently unique configuration that improves atomization of the fuel/air mixture to achieve improved fuel economy and/or increased brake horsepower output.

Filed: 1994-10-21
Abstract: A bridge for interconnecting data network includes an adapter connected to each network and a central programmed processor. Each adapter receive and transmit FIFO storage which is less than the packets being transferred from one network to the other. The control program generates Receive Buffer Descriptors which include buffer pointers, buffer length fields and pointers to next descriptors. These Descriptors are used by the adapters to buffer received packets which are directed to another network. When a packet is buffered the control program generates Transmission Descriptors which are used by the adapter to transfer packet data to the other network. The control program modifies packet when needed by by generating and storing in its memory only the modified portion and including in the Receive Buffer Descriptor pointers which the buffered information which is to be transmitted and the sequence.

Title: Disposable, compactable, shape-restorable package for storing and dispensing dry or premoistened sheets
Inventor: YOUNG MARK DOUGLAS
IPC: B65D83/08
Filed: 1993-06-21
Abstract: A disposable, compactable package for reliably dispensing a stack of sheet products even after the package has been deformed or compacted. The package comprises a top wall and a bottom wall comprised of a resiliently deformable material. The top and bottom walls are spaced from and oriented generally parallel to one another. They are connected to one another about their peripheries by means of a thinner more easily deformable substantially continuous tube or hoop which is also comprised of resiliently deformable material. The substantially continuous tube or hoop, which is preferably integrally formed with either the top wall, defines the side walls of the package. The tube, which may be of any desired cross-sectional shape, is also produced from material having a sufficient resilient memory that it easily and resiliently deforms when the external force is applied to the package, yet by virtue of its tubular configuration and its resilient memory exhibits a strong tendency to self-restore once the external applied force is removed. The package, which is preferably rectangular, includes a preformed dispensing aperture or means for providing a dispensing aperture in its top or its bottom wall. The dispensing aperture is smaller than the cross-sectional profile, i.e., the cross-sectional "footprint", of the sheet products contained within the stack to retain the sheet products inside the package throughout the package's useful life. The sheet products may be in discrete or continuous form.

Filed: 1993-08-09
Abstract: The invention relates to a device for lowering or raising people and/or loads over great heights, in which a rope pulley is rotatably fitted on a base plate via a brake disc. A brake pad is allocated to the brake disc on one side on the base plate and on the other on a pressure plate secured against rotation. Pressure can be applied to the pressure plate by a tension bolt passing through the brake disc bearing and the tension bolt is coupled to the suspension of the device via a power deflection device via which the weight of the person and/or load to be lowered or raised can be converted into a tensile force on the bolt. A concentrically arranged toothed wheel is connected to the brake disc which engages with a gear system also fitted in the base plate via which an additional centrifugal braking device can be actuated. Here, the suspension (16) of the device takes the form of a pull-rod (15), preferably guided to be movable on the base plate (1), the end (19) of which, which is in the device, can pivot on an arm of a bell-crank lever (17), the other arm of which is pivot-ably connected to the tension bolt (9) and which is fitted to pivot on the base plate (1) in the region of its angle (20).
