Patent GB-8422276-D0 (GB)
Title: Rotary valve
IPC: F16K11/074
Filed: 1984-09-04
Abstract: A rotary valve includes a rotor (132) having at least one internal flow passageway (76,78) therein extending between ports (80, 82, 84, 86) for providing communication between various pairs of flow passageways in the body (12) of the valve. The rotor includes an annular surface (88) for sealing engagement with the body, at least one of the rotor ports being disposed on the annular surface. A continuous resilient seal (70) is disposed between the sealing surfaces of the rotor and the body to provide static and dynamic sealing. A spherical surface (124) disposed between the rotary drive and the rotor applies axial pressure to the rotor, the surface accommodating rocking of the rotor to insure uniform loading thereof. Further, loading of the seal between the rotor and body is adjustable externally of the valve by manipulating an adjustable element (36). <IMAGE>

Title: Apparatus and method for minimizing the turn on time for a receiver operating in a discontinuous receive mode
IPC: H04B1/16
Filed: 1995-07-17
Abstract: An apparatus and a method for minimizing the turn on time for a receiver operating in a discontinuous receive mode. In a communication unit the receiver receives a signal (118) having desirable data (word A) and undesirable data (word B). The receiver (104) has a discontinuous receive mode of operation wherein the receiver (104) is turned on when expecting the desirable data (word A) and turned off when expecting the undesirable data (word B). A duration of time that the receiver (104) has been turned off is determined. The receiver (104) is turned on at time prior to the arrival of the desirable data (word A) responsive to the duration of time that the receiver (104) has been turned off. The present invention advantageously minimizes the turn on time for the receiver (104) operating in a discontinuous receive mode to save current drain.
