Title: Radio with peak power and bandwidth efficient modulation
Inventor: MILLER SCOTT L
IPC: H04L27/34
Filed: 1996-05-23
Abstract: A communication device (300) includes a digital modulator (301), a Digital Signal Processor (306), and an amplifier (312). The digital modulator (301) includes an information generator (304) and a peak suppression device (402).  The peak suppression device (402) includes a symbol mapper (404) and a symbol scaler (406).

Title: Extendible safety posts for manhole ladders
Inventor: LORENTZ GARRY
IPC: E06C7/18
Filed: 1998-02-02
Abstract: A retractable safety post for facilitating access in and out of a manhole is sli dably attached to each side rail of a wall-mounted ladder. Each post slides within a t ubular sleeve fixed to the side rail and is selectively movable between a retracted or stowed position to an extended or use position. Each post has at its upper end a cap an d handle for ease of grasping during use, and at its lower end a latch member for securin g the post in its extended position during use. A wall bracket anchoring the ladder to the manhole serves as a resting support for the latch member and its post when in the extend ed position. The post is secured in the extended position by merely lifting the pos t, twisting the post a given amount in a pre-set direction, and lowering the post slightly s o that the latch member can engage the wall bracket. In its stowed position, the post rests wholly within the manhole.

Patent CA-2234501-A1 (CA)
Inventor: HOPTROFF RICHARD
IPC: A47F10/00
Filed: 1998-04-09
Abstract: A radio transmitting device includes a radio transmitter for one or more customers with which customers may attract the attention of a service provider. The radio transmitter emits a coded signal which includes a key that identifies the transmitter (and therefore the customer), and also, potentially, the customer's specific requirement. One or more radio receivers are employed by the service providers to respond to customers' calls for service.  These log the customers who require attention, and potentially the nature and urgency of their need, the time of their request and the number of calls they have placed since they were last responded to.

Patent CA-2238532-A1 (CA)
Title: A system for establishing a three-dimensional garbage matte which enables simplified adjusting of spatial relationships between physical and virtual scene elements
Inventor: ROHLFING THOMAS R
IPC: H04N5/272
Filed: 1998-05-25
Abstract: A new method and apparatus for creating, positioning and manipulating a garbage matte which obscures everything outside of a three-dimensional physical set or blue stage. Effectively, the garbage matte is a "negative" of a blue stage. What is important is that the garbage matte is created either as a virtual enclosure around all virtual objects in the virtual environment, or simply as a background color of the graphics engine generating the garbage matte. In this way, the garbage matte provides extensions of blue screens which comprise the blue stage, extending all the way around and behind the television cameras. Consequently, a compositor will not include in a composited output image those physical set elements which are masked by the virtual garbage matte. The compositor will replace areas hidden by the garbage matte with image data supplied by the computer image generator which stores the virtual environment. Furthermore, it is now possible to move the virtual location of the physical set (including the television cameras) within the virtual environment without having to readjust the position of the garbage matte relative to the model by anchoring virtual objects together so as to maintain relative position relationships at all times.

Patent CA-2259004-A1 (CA)
Inventor: TSAI MINGLIANG
IPC: B32B7/12
Filed: 1997-06-04
Abstract: The present invention provides highly oriented multilayer films. They are produced by coextruding or laminating films having at least one layer of a fluoropolymer, at least one layer of a polyolefin homopolymer or copolymer and an intermediate adhesive layer of a polyolefin having at least one functional moiety of an unsaturated carboxylic acid or anhydride thereof. With this structure the polyolefin layer allows the fluoropolymer layer to be stretched up to ten times its original length. Such a high orientation ratio for the fluoropolymer film increases the mechanical strength, toughness, and water vapor barrier properties of the film while using a thinner gauge fluoropolymer film. Coextrusion processing can be done at higher temperatures, i.e. in the range of from at about 280 ~C to about 400 ~C. These temperatures allow films to be produced in the absence of polymer degradation and film melt fracture.

Patent CA-2264440-A1 (CA)
Inventor: POLON JAY
IPC: E03B1/00
Filed: 1999-03-02
Abstract: A rainfall collection system extending over a wide area funnels collected rainwater into a central storage tube. A platform consisting of a plurality of water-impermeable membrane panels laid over a graded bed overlays a flexible watertight collection tube disposed within a swale running along the apex of the bed beneath the membrane panels.  Rainwater is automatically pumped into the collection tube as it accumulates on the membrane panels, preventing losses due to evaporation and percolation into the ground. The collected rainwater is stored in the storage tube and transported by an aqueduct system or tank trucks. The membrane panels may be transparent or translucent, allowing maintenance personnel to detect leaks in the panels by darkened areas of the ground visible via aerial inspection, and may be marked with coordinate identifiers allowing maintenance personnel to readily locate damaged areas from the ground. A grid of maintenance corridors interspersed throughout the collection platform allows access to the membrane panels for maintenance and repair. Sediment catchment pits may be located near each end of the tube to collect sediment.

Title: Process for the simultaneous preparation of acrylonitrile and acrylic acid
Inventor: IHARA TATSUYA
IPC: C07C51/215
Filed: 1997-11-17
Abstract: A process for the simultaneous preparation of acrylonitrile and acrylic acid in the process for the preparation of the nitrile or the acid by gas-phase catalytic oxidation of propane with ammonia and oxygen in the presence of a metal oxide catalyst containing as the essential components vanadium and at least one element selected among tellurium, antimony and molybdenum, characterized by regulating both the molar ratio of propane to ammonia and that of oxygen to ammonia each within the range of 2 to 10. Conducting the ammoxidation of propane at the selected molar ratios of propane to ammonia and oxygen to ammonia enables the simultaneous preparation of acrylonitrile and acrylic acid at a high total selectivity and in a high total yield. Further, the catalytic activity can be retained for a long period, so that the ammoxidation can be conducted efficiently and stably for a long period.
