Patent CA-2161921-A1 (CA)
Inventor: CARR LARRIE
IPC: H04B10/27
Filed: 1995-11-01
Abstract: A plurality of data streams time-division multi-plexed into a single stream are concurrently processed. State vectors characteristic of each data stream are stored in unique read-write memory locations having known ad-dresses.  During an initial clock cycle the next sequential data word is received from the single data stream and an input state vector characteristic of the data stream in which the received data originated is retrieved from the memory.   The data word and the input state vector are passed to state machine logic which, during one or more intermediate clock cycles, processes the data word and the input state vector to produce an output data word and an output state vector.  During a final clock cycle the output data word is transferred to an outgoing data stream and the output state vector is stored in the memory location from which the input state vector was retrieved.  The process repeats sequentially, with the next group of three clock cycles commencing immediately after the initial clock cycle of the immediately preceding group of three clock cycles.

Title: Local isdn radio transmission system
Inventor: SCHIFFEL REINHARD
IPC: H04Q7/24
Filed: 1994-07-28
Abstract: A local ISDN radio transmission system is organized as a local radio cell that consists of a central stationary radio station and of a plurality of decentralized subscriber radio sets.  The radio transmission system is connected to the access connection elements (ISDN base access ports) of a local central office, subcentre or private branch exchange. The number of radio subscribers is larger than the number of used duplex radio channels.  The invention ensures to the radio subscribers a connection with a So-interface.  The radio transmission in the subscriber area allows covering and propagation time problems encountered in the case of wire transmission.  According to the invention, the radio transmission arrangement is inserted into a ISDN two-wire access connection circuit with an intermediate repeater, in the section that extends between the intermediate repeater and the network termination.  After an activation request, a radio channel is allocated within the carency and monitoring times for activating the ISDN two-wire access connection circuit.  In order to ensure an efficient use of the available transmission bandwidth, an independent radio channel for control, organization and monitoring purposes is dispensed with.  The required instructions and information are transmitted in the free radio channels.  The subscriber radio sets recognize free channels thanks to a special arrangement of the synchronization word that differs from that of the ISDN transmission.

Title: Submarine cable having a bi-metal tube core containing optical fibers
Inventor: CHU TEK-CHE
IPC: G02B6/44
Filed: 1996-04-11
Abstract: It is an object of the invention to provide an optical fiber cable having hermetically-sealed optical fibers and excellent strength characteristics without utilizing a costly welded steel tube. It is a further object of the invention to provide an optical fiber cable that is capable of efficient and fast manufacture. These and other objects are provided by an optical fiber cable employing a novel cable core, the cable core comprising an inner, longitudinally extending, substantially-closed C-section tube; and, an outer, hermetically-sealed, longitudinally extending outer tube disposed concentrically around the C-section tube in a substantially close-fitting manner. Advantageously, the C-section tube assists in protecting the optical fibers against crush, impact and pressure, and may also enhance the tensile strength of the optical fiber cable. The use of the C-section tube also allows the optical fibers to be efficiently introduced into the interior cavity of the C-section tube during cable production. And, as the C-section tube provides the desired strength characteristics of the cable core, the outer tube may be advantageously optimized to hermetically seal the optical fibers in the cable core. Thus, the outer tube may be designed, for example, according to its sealing characteristics and manufacturability without significant regard for mechanical characteristics such as strength.

Title: Whipstock apparatus and methods of use
Inventor: SIEBER BOBBY G
IPC: E21B47/09
Filed: 1995-02-21
Abstract: An oil field Whip-Anchor System, for deviating a wellbore, which uses an improved whipstock (1) incorporating a new setting apparatus and method, attached to a mechanical (14M) or hydraulic anchor packer is disclosed. The complete Whip-Anchor System also includes an apparatus and method for retrieving the Whip-Anchor if it is used in wellbores which require retrievable wellbore deviation tools. The new apparatus reduces the number of whipstock bodies that must be warehoused to three fundamental types which fit all commonly used wellbores. The apparatus permits the proper "set" of a mechanical packer without fear of shearing the releasable attachment device currently used in the industry and permits an operator to "bottom hole wash" while setting a mechanical packer in a wellbore. The same apparatus and similar techniques are used for both mechanical or hydraulic packers. The system utilizes a slot cut in the face (11) of the whipstock for setting (13) and retrieval (12). Other improvements include a pinned spring loaded hinge assembly (6) which assures that the tip of the whipstock will fall against the wellbore, a deflector plate (7) that uses a surface hardening or polycrystalline diamond inserts to reduce wear on the top portion of the device during the window milling operation. Also disclosed are additional downhole tools for use with the Whip-Anchor System.

Title: Food molding apparatus and method of forming food products
Inventor: LONDON EUGENE J
IPC: A23P1/10
Filed: 1996-07-08
Abstract: The invention provides a molding apparatus and process of molding formable materials which comprises at least one supply manifold for receiving a formable material and plungers or pistons for applying pressure to the formable material within the manifolds. A mold plate including at least one mold cavity is driven between fill and discharge positions, with the at least one mold cavity selectively exposed to the supply manifold when in the fill position. A clamp member is positioned adjacent the mold plate when in the fill position, and pressure is applied on the clamp member to clamp the mold plate against the supply manifold. The clamp member and associated structure apply pressure to the clamp member compensating for deflection of these structural members which maintains the mold plate in firm clamping relation relative to the supply manifold. The clamp plate therefore does not operate in flexure, and eliminates the need to provide the clamp plate with a thick cross section or heavy mass which would accommodate forces normally encountered during filling of the mold cavities. In this manner a mold plate having a relatively thin section, and a clamp member also of relatively thin section may be utilized, to allow a machinehaving significantly increased width to be realized. The significantly increasedwidth of the machine will correspondingly increase capacity, and also allows compatibility with other processing equipment.
