Patent FI-20080001-A (FI)
Inventor: LOMP GARY
IPC: H04B17/00
Filed: 2008-01-02
Abstract: A multiple access, spread-spectrum communication system processes a plurality of information signals received by a Radio Carrier Station (RCS) over telecommunication lines for simultaneous transmission over a radio frequency (RF) channel as a code-division-multiplexed (CDM) signal to a group of Subscriber Units (SUs). The RCS receives a call request signal that corresponds to a telecommunication line information signal, and a user identification signal that identifies a user to receive the call. The RCS includes a plurality of Code Division Multiple Access (CDMA) modems, one of which provides a global pilot code signal. The modems provide message code signals synchronized to the global pilot signal. Each modem combines an information signal with a message code signal to provide a CDM processed signal. The RCS includes a system channel controller coupled to receive a remote call. An RF transmitter is connected to all of the modems to combine the CDM processed signals with the global pilot code signal to generate a CDM signal. The RF transmitter also modulates a carrier signal with the CDM signal and transmits the modulated carrier signal through an RF communication channel to the SUs. Each SU includes a CDMA modem which is also synchronized to the global pilot signal. The CDMA modem despreads the CDM signal and provides a despread information signal to the user. The system includes a closed loop power control system for maintaining a minimum system transmit power level for the RCS and the SUs, and system capacity management for maintaining a maximum number of active SUs for improved system performance. <IMAGE>

Abstract: 1,230,826. Pulse oscillator. BURROUGHS CORP. 9 Aug., 1968 [14 Aug., 1967], No. 38048/68. Heading H3T. [Also in Division G4] An oscillator producing pulses at D includes a L-C circuit 1, 2 receiving regenerative feedback from D (through a resistor 24) and has a signal inverter (e.g. a transistor 4) and a current amplifier (e.g. an emitter follower 13) connected before the L-C circuit and the output D; a further circuit (e.g. a transistor 26) being provided to inhibit the oscillator when a positive signal is applied at B. The positive signal at B causes transistor 26 to conduct and hence earths the base 15 of emitter follower transistor 13. The frequency of oscillation is varied by a series of a parallel resistor in the L-C circuit (Figs. 1A, 1B, not shown), the L-C circuit having a low Q. Three such oscillators are used (Fig. 4, not shown) as timers in a digital information retrieval system for a disc store in which three zones of information are stored at different frequencies. Each oscillator has a frequency of nine times the stored bit frequency of the respective zone, and a selected one is turned on by a zone selector circuit (56) which removes a normally applied positive signal from a corresponding OR-gate (e.g. 57). Synchronization of the selected oscillator with the clock track of the selected zone is effected by supplying to the OR gates the output of a read-out head (59) sensing the clock pulses, which are of lower frequency than the oscillator output pulses; the operating oscillator is then turned off at intervals (in this case, every ninth oscillator pulse) by the clock pulses (B, Fig. 3, not shown), the start of the first pulse of a new train of oscillator pulses coinciding with the end of each clock pulse.

In an arrangement for cooling the connecting flanges 1a, 1b of the casing halves of a saturated or wet steam turbine to prevent inadmissible temperature gradients upon sudden reduction in turbine load, axially extending cavities 2 are provided in the flanges 1a, 1 b and connected to the rotor chamber through passages 3. During steady running of the turbine condensate collects in the cavities 2, but with a sudden reduction in load the reduction in pressure causes the collected condensate to evaporate into steam, taking up latent heat and thus cooling the outer portions of the flanges 1a, 1b to reduce thermal gradients. The steam so formed flows through passages 3 and past restrictions (9), Fig. 3 (not shown), into the rotor chamber, baffles (10) preventing the issuing steam from impinging on and damaging the rotor blades. In this arrangement the cavities 2 are sealed off from the outside by plugs (5), Fig. 2 (not shown). However in a modification, the cavities 2 are connected at 7 to pipes leading to a region of lower pressure, such as the condenser. Valves in the pipes are opened automatically or manually in the event of a sudden reduction in turbine load, thus allowing steam to flow from the rotor chamber through passages 3, cavities 2 and the pipes to the condenser to cool the outer portions of the flanges 1a, 1b.
