Patent CA-2030532-A1 (CA)
IPC: C08K3/00
Filed: 1990-04-10
Abstract: A syndiotactic polypropylene resin composition comprising a polypropylene having a substantially syndiotactic structure and a nucleating agent.  The syndiotactic polypropylene may be a homopolymer of the propylene, a copolymer of the propylene and a smaller amount of another olefin or a mixture of the above-mentioned (co)polymer and an isotactic polypropylene.          The resin composition preferably has a higher crystalli-zation temperature than a polypropylene containing no nucleating agent by 5°C or more, as measurement is made by a differential scanning thermal analysis.

Abstract: Abstract of the Disclosure A process for manufacturing a slotted hole screen is suggested, wherein the slotted screen is particularly suited for use in devices for the sorting or cleaning treamtment of aqueous fiber suspensions, for example in paper manufacturing.  In the process, cross bars are attached onto wire- or bar-shaped longitudinal members defining the screen slots.  In order to substantially reduce the danger of the catching and thus the flocking and/or web formation of fibers in the suspension on the slotted hole screen during the subsequent operation of the screen, the joints between the longitudinal members and the cross bars are provided with coverings having a smooth surface out of a solder or another smoothly flowing, solidifying material on their exposed surfaces.

Title: Anoxic poultry stunning
Inventor: AUDSLEY ANTONY R S
IPC: A22C21/00
Filed: 1990-12-05
Abstract: Prior to slaughter, poultry are caused to undergo anoxic convulsions by exposure to an atmosphere for a sufficient period of time to lose consciousness. The poultry are then slaughtered. After slaughter, the poultry are chilled and then deboned or portioned. It is found that deboning or portioning can be performed within four hours of slaughter, instead of the conventional period of twelve hours or more, without adversely affecting the quality of the resultant meat. This result is attributed to the anoxic convulsions causing glycolysis in the pectoral and other muscles of the birds.

Title: Apparatus for picking up, transporting and unrolling large bales of hay
Inventor: LOVE PHILLIP W
IPC: A01D87/12
Filed: 1991-04-30
Abstract: ABSTRACT OF THE DISCLOSURE    An improvement in a self-loading apparatus for picking up and moving a bale of hay having diameters of up to about 3 or 4 feet and longitudinal lengths of up to about 5 or 6 feet.  The apparatus is of the type including a main frame member supported on wheels mounted near the end of the main frame.  A hitch frame has one end pivotally connected to the front end portion of the main frame, with the other end of the hitch frame adapted for attachment to a tow vehicle.  The main frame is adapted to be tilted upwardly about the support wheels when braking means on the wheels are activated and the tow vehicle is backed up.  A pair of load engaging and clamping swing arms are pivotally attached to the respective sides of the main frame.  Means are provided with the main frame and hitch frame for pivotally moving the swing arms away from each other when the main frame is tilted upwardly and, conversely, for pivotally moving the swing arms toward each other when the main frame is lowered by moving the tow vehicle forward while the braking means on the wheels of the main frame is activated.          The improvement of the present invention provides means for allowing the bale of hay to lie on the ground and be unrolled along the ground by pulling the apparatus forward.  Unrolling the bale in such manner provides a long strip of hay for feeding animals.
Patent CA-2042651-A1 (CA)
Title: Ostomy device with improved coupling system
Inventor: EDWARDS JOHN V
IPC: A61F5/448
Filed: 1991-05-15
Abstract: In the first embodiment, the faceplate coupling ring is of conventional design and includes an axially extending rib with a radially outwardly extending rim and a radially inwardly extending deflectable sealing strip. The pouch coupling ring includes inner and outer spaced walls, forming a channel for receiving the rib. First and second protrusions extend inwardly from points on the interior surfaces of the walls proximate the ends thereof. The first protrusion cooperates with the rim and the second protrusion cooperates with the tip of the sealing strip, to securely retain the rib within the channel. The walls of the channel have reduced thickness and are easily deflectable as the rib is inserted into the channel, such that coupling of the rings is facilitated but decoupling requires the conventional amount of force due to the second protrusion. In the second embodiment, the deflectable sealing strip on the faceplate coupling ring is replaced by a rigid flange which cooperates with the second protrusion to substantially increase the decoupling force.

Title: Method and apparatus for a distributive wide area network for a land mobile transmission trunked communication system
Inventor: BARNES KEITH W
IPC: H04B7/15
Filed: 1990-03-30
Abstract: An alternate home channel for a land mobile transmission trunked communication system designates one of a plurality of repeaters for a given site or coverage zone as an alternate home repeater. The control signals transmitted over the subaudio band for all home channel repeaters in that site are also duplicatively transmitted over the subaudio band of the alternate home repeater. Each mobile transceiver will be programmed with two channel numbers. One for the home repeater and the other for the site alternate home repeater. When the power is turned on, the mobile transceiver determines which repeater to monitor by scanning both the home and alternate home channels. When a valid control message is detected on either channel, that channel becomes the monitor channel. Operation of the mobile transceiver is then generally similar to prior operation, with the exception that the monitor channel (either home or alternate home channel) is used instead of just the home channel.

Abstract: In an automatic loading system and method, wheeled carts  receive, e.g.,  five or  six  layers  of  newspaper bundles of, e.g., four to six bundles per layer.  Conveyors move bundles to a platform of independently-operated sec-tions selectively halted upon receipt of a bundle.

Pusher elements are responsive to the presence of bundles upon predetermined ones of the sections for pushing the bundles in a trans-verse direction onto a split platform.  The split platform comprises first and second platform sections which are movable between a closed position, wherein adjacent edges of the platform sections are in close proximity, and an open position wherein the sections are moved apart to define a gap region between the split platform sections, the gap region being positioned immediately above the open end of the cart.  Structure is responsive to delivery of bundles by the pusher elements upon the split platform assembly for moving the split platform sections apart, whereupon the bundles resting thereon are dropped through the gap region toward the cart.

Title: Cellular data overlay system
Inventor: SLEKYS ARUNAS G
IPC: H04W72/12
Filed: 1992-03-24
Abstract: A cellular telephone system includes a packet-switched digital data communication subsystem overlaying a circuit-switched (e.g., voice) communication subsystem, with voice and data services sharing the same voice channels. The voice communication subsystem provides voice services independently of the operation of the data communication subsystem. On the other hand, the data communication subsystem monitors use of the voice channels for voice communication, and, in response thereto, temporarily allocates one or more of the available voice channels for data service. In a preferred embodiment, each data basestation transmits, from time to time, an available-channel signature to identify those, if any, of the data-allocated channels that are not then being used to transmit voice or data. For data communication, a remote unit monitors selected voice channels in the coverage area of the cellular telephone system for available-channel signatures, selects one of the channels (if any) identified by the signature thereon as being available for data transmission, and transmits or receives digital information over that channel.
