Title: Rubber building panel and method of manufacturing same
Inventor: CIAO ANGELO
IPC: B01F27/91
Filed: 1997-01-10
Abstract: The present invention relates to the use of rubber fragments from discarded tires in building panels, including panels suitable for house construction. A rubber panel is constructed of metal frame members, using a metal mesh on the interior for structural strength and support, and ground up rubber fragments which may contain strands of steel or other metal or fibre reinforcing materials present in tires. These fragments are mixed with an appropriate glue and bonded together to ensure the structural integrity of the panel. Different types of panels are made wherein a window or door frame is mounted at a suitable location.      The method of manufacturing a rubber panel includes the steps of preforming a metal frame with mesh covering enclosed area, mixing an appropriate glue with shredded vehicle tires to form a mixture, place the mixture over the mesh, clamping the panel and placing it under pressure by a press and maintaining the pressure until the glue has set. Fine rubber particles or a cement mixture can be applied over at least one exterior surface to create a smooth surface.
Patent CA-2196738-A1 (CA)
Inventor: SOUSA JOHN G
IPC: G02B6/32
Filed: 1997-02-04
Abstract: A focusing assembly includes features that allow numerical aperture to be reduced and optimized by reducing aberrations and ghost reflections and easily controlling stop size, thereby increasing depth-of-focus.  The assembly includes a single, bi-aspheric focusing lens that optimizes image quality at a specific off-axis field point.  Passage of excessively divergent radiation is prevented by a baffle having a sharp, flared edge that minimizes reflection.  A second aperture or baffle can be included to restrict high-divergence radiation emerging from the bi-aspheric focusing lens.  All interior surfaces of the focusing assembly are preferably blackened, once again to minimize internal reflections.

Patent CA-2206230-A1 (CA)
Inventor: MANGOLD ANDREAS
IPC: F16B12/14
Filed: 1997-05-27
Abstract: Known bolted connections for the internal connection of two profiles have a fastening rod which is intended for insertion into the profiles and has two threaded parts each projecting into a connecting hole of the profiles. Connection is effected by using two fastening nuts which are intended to be fitted onto the two threaded parts and can be tightened against the connecting holes. This type of clamping has a substantial disadvantage. Thus, screwing of the two fastening nuts is made more difficult by virtue of the fact that, during tightening, one nut must be held with a first wrench while the other nut can be tightened with a second wrench. The bolted connection according to the invention does not have this disadvantage. This in fact permits the use of only one nut. To prevent the fastening rod from rotating when the nut is turned or slackened, the fastening rod is provided in an end section with at least one constriction so that a clamping jaw fitted onto this constriction in an axially nondisplaceable manner prevents rotation of the fastening rod.

Title: Full service dispatcher for satellite trunked radio service system
Inventor: SWEET RICHARD S
IPC: H04W4/06
Filed: 1997-11-18
Abstract: In a mobile communication system, a system for providing communication between multiple users in a closed user group arrangement includes first and second mobile earth terminals (METS) registering with the mobile satellite system. The first MET selects a closed user group network identifier (NET ID) representing a NET group to establish voice communication therewith and transmits the NET ID to a central controller. The central controller receives the NET ID from the first MET, validates the first MET for communication, validates the NET ID, allocates a frequency for the NET group, and broadcasts the message to the NET group informing the NET group of the allocated frequency. The second MET tunes to the frequency in response to the message broadcast by the central controller. A full service dispatch (FSD) system monitors and displays detailed conference activity. The FSD system provides a display conference function that displays all the conference activity usage data; provides a display active conference function that displays updated information in real-time for active conferences; provides a monitor conference function permits selective monitoring of one or more conferences; and provides a monitor user function that permits selective monitoring of one or more users.

Abstract: A data transmission system for a vehicle includes a plurality of control systems installed on the vehicle, and a network bus connecting the plurality of control systems with each other for circulating a transmission right through the plurality of control systems to thereby perform transmission of a message between the plurality of control systems.  According to a first aspect, each of the control systems starts transmitting data when it is detected that the transmission right is not generated or lost from the system, and continues transmitting the data when no collision of data transmitted from the present control system with data transmitted from the rest of the plurality of control systems, or when by mediation for avoiding the collision is detected, it is determined to continue data transmission.  According to a second aspect, the maximum number of times of retransmission to be permitted is determined according to a type of failure in transmission identified, and the retransmission is performed so long as the number times of retransmission of the data does not exceed the maximum number of times of retransmission to be permitted.  According to a fourth aspect, the message comprises a first response field for receiving a first acknowledging response output from a control system having received the transmission right, and a second response field for receiving a second acknowledging response output from a control system having received data.
