Patent CA-2033309-C (CA)
Title: Frame synchronization system among multiple radio base stations for tdma digital mobile communications system
Inventor: KONDO SEIJI
IPC: H04J3/06
Filed: 1990-12-27
Granted: 1998-02-10
Abstract: A TDMA digital mobile communications system prevents TDMA frame synchronization from being asynchronous among radio base stations when a communication held by a mobile station is handed over from one service area to another.          A control station sends a reset pulse for TDMA frame synchronization to the radio base stations each being situated in a particular service area over communications cables.  In response, the radio-base stations each generates a TDMA frame.  The control station has a synchronous signal generator for generating the reset pulse while each radio base station has a time delay adjustment unit for adjusting the time delay of the reset pulse.  The synchronous signal generator and the time delay adjustment units of the individual radio base stations perform measurement and setting such that a reset signal has the same time delay between the control station and all of the radio base stations.  Hence, regarding a TDMA signal which the mobile station receives, TDMA frame synchronization is immediately set up at the time of hand-over and thereby prevents a voice signal from being interrupted.

Title: Antibody antagonists of human interleukin-4
Inventor: RAMANATHAN LATA
IPC: A61K38/00
Filed: 1990-12-18
Granted: 2002-04-30
Abstract: Two kinds of antibody antagonists of the binding of human IL-4 to cellular receptors are provided by this invention. Some of the antagonists bind to specific regions of IL-4 which are believed to be involved in interactions between IL-4 and its receptors. Because of this specific binding by the antibodies to the IL-4, the binding of the IL-4 to the receptors is substantially inhibited. The other antibody antagonists of the invention are anti-idiotypic antibodies which, while lacking IL-4 activity, appear to mimic IL-4 and to compete directly with it for binding to the cellular receptors.  Polypeptides used to make the antibody antagonists are also provided, together with methods for using the antagonists to inhibit the binding of IL-4 to its cellular receptors.

Abstract: A stop sign and/or crossing arm deployment system is secured to a side and/or the front, respectively of a school bus for deploying a safety stop sign and/or crossing arm between a retracted normal state and a deployed safety state.      A dual power circuit is provided for providing maximum power at the instance of deployment and at the instance of final retraction. Otherwise, a lower power is used to operate a bi-directional DC motor which receives power for the entire time period between deploying and retracting the system. The system provides the lower power level while simultaneously heating the circuitry including the motor for use in cold climates. A single ground switch is used for coupling the motor directly to ground both during the deployed state and retracted state to provide maximum power in momentary cycle times to the motor. A voltage, in the reverse retraction direction of the motor, is applied to the system at all times to immediately commence the retraction portion of the cycle during deployment should the system be deployed and that decision is followed by a decision to cancel such deployment.
