Patent CA-2206569-A1 (CA)
Title: Receiver module for receiving extremely high frequency electromagnetic directional radiation fields
Inventor: ROTHE LUTZ
IPC: H01Q9/04
Filed: 1995-12-01
Abstract: The invention is based on a planar concept and involves the configuration of a planar radiating element with the property of generating wide-bande electromagnetic radiation fields with circular field polarisation. A wide-band radiating element is developed in which the radiating and excitation network planes are separated and excitation of the radiating element is achieved using a coupling waveguide comprising a group of highly conductive planar elements stacked along the normal to their (large) surfaces above a conductive ground plane; to ensure a large radiation bandwidth, the highly conductive planar elements are placed well above the conductive ground plane and their highly inductive coupling components (which are connected to the ground plane) are compensated by special coaxial waveguide diaphragms whose ellipticity of the circular polarisation is adjusted solely by circular or square diaphragms within the planar contour, without affecting the radiating edges.

Title: Process for making expanded slag
Inventor: MACKENZIE PETER A
IPC: C21C5/36
Filed: 1997-06-13
Abstract: Metallurgical slag is expanded to produce a lightweight solid by forming a stream of molten liquid slag of controlled rate of flow and mixing the stream of slag with a controlled quantity of water and flowing the interacting mixture of slag and water into a receptacle. The interaction between slag and water is allowed to proceed for a predetermined period of time to form an expanded solid without theaddition of any additional cooling water which would otherwise quench the material and vitrify it. In the receptacle, a vaned rotor operates to segment the interacting mixture of slag and water and project the segmented mixture through the air for collection into a heap.

Title: Expanded foam products and methods for producing the same
Inventor: MARSON JAMES E
IPC: B29C53/26
Filed: 1996-01-03
Abstract: An expanded resilient product (130) having a plurality of slits formed therein is disclosed. One embodiment has a plurality of slits formed in a resilient material thereafter the material is extended to produce an expanded material which is then bonded to at least one surface in order to retain the expanded nature of the product. In another embodiment, each slit is defined by a first internal surface (170) having a protruding portion (160) and second internal surface (172) having a recess portion (168) corresponding to the protruding portion of the first surface which together form an interlocking fit between the two. Forces are applied to the product to dislodge a protruding portion from the recess portion, thereby forming a plurality of gaps (174). The product is then permitted to relax to prevent the protruding portions from re-engaging the recess portions and thereby maintaining the expanded nature of the product.

Patent CA-2216249-A1 (CA)
Inventor: MUSGRAVE KENNETH C
IPC: A61M39/04
Filed: 1997-09-23
Abstract: A self-healing seal is provided which is particularly adaptable for use in medical applications. The seal includes a housing which defines an interior volume. The housing is formed of a rigid or semi-rigid material such as a rubber or other elastomeric material. A viscous flowable material is disposed within, and substantially fills, said interior chamber of the housing. The viscous flowable material is typically a gel, such as silicone gel. The self-healing seal is configured such that if it is penetrated by an object such as a hypodermic needle, when the needle is subsequently removed, the viscous flowable material flows in such a manner as to fill the space previously occupied by the penetrating object. At the same time the housing is sufficiently elastic to maintain the viscous material within the interior volume of the housing. In this manner a liquid impermeable seal is formed.

Filed: 1997-12-17
Abstract: A data communications system includes a standard tele-communications apparatus (1) arranged to transport analogue signals in a form of Adaptive Differential Pulse Code Modulated (ADPCM) digital signals generated from Pulse Code Modulated (PCM) digital signals representative of the analogue signals. A mapping data processor (13) coupled to a source (14) of digital data and to an ADPCM encoder (3) of the standard telecommunications apparatus (1), generates PCM coded symbols representative of the digital data in accordance with a predetermined mapping function. An unmapping data processor (15) connected to an ADPCM to PCM decoder (10) of the apparatus (1) operates to re-generate the digital data from communicated PCM signals. The mapping and unmapping data processes are arranged in combination with the PCM and ADPCM encoding and decoding operations to provide a substantial increase in a rate of data communication, with respect to a data rate which would be achieved if the digital data were to be converted into analogue signals and fed to a PCM encoder of the standard telecommunications equipment.

Title: Peak flavor protein roux
Inventor: SEEDS W R
IPC: A23L19/18
Filed: 1996-05-10
Abstract: Peak flavor protein rouxs having applications in food products such as gravies, saucies, soups, breadings, stuffings and as flavor carriers are produced from protein food sources such as protein concentrates from vegetable, animal, dairy, fish and foul food sources which when mixed with shortening and caramelized to a specific color yield a peak flavor roux caramelized protein. The protein roux exhibiting a peak flavor which is correlatable to a specific color is achieved as a result of mixing, heating, caramelizing and quenching of the protein food source and oil mixture upon reaching a specific color - peak flavor. In addition, a snack chip composition and a snack chip having reduced oil content is provided by utilizing the peak flavor rouxs in conjunction with power or particulate vegetable sources and processed by air baking of the chip materials resulting in a reduced oil peak flavor chip.

Inventor: DONNER GARRETT J
IPC: A63B57/00
Filed: 1996-08-15
Abstract: The present invention provides for projecting supported objects, such as baseballs, footballs or golfballs.      The apparatus (100, 200, 300) includes a movable striker (140, 220, 320) having a first surface (144, 227, 321) (a target surface) for receiving a force, and a second surface (145, 225, 322a) (a projecting surface) for projecting the object, with the object being supported by a supporting surface (132, 225, 322b). The supporting surface may be a portion of the second (projecting) surface or another surface on the striker, or alternatively may be portion of a support member (130) separate from the striker. The target surface receives a force from the user, the force being subsequently transmitted through the striker to the supported object via the projecting surface. The striker may be movably coupled to a base (110, 210, 310) with the striker being limited to fore-and-aft movement relative to the base, so that the object will be projected forwardly in a predetermined direction even if the target surface is not struck in a squarely forward direction. The striker may also be adapted to be positioned in a second, operative position, in such a way that the apparatus supports the object and allows the user to strike the object directly.
