Title: Sheet hopper
Inventor: RAKER JOHN W
IPC: B65H45/22
Filed: 1990-03-16
Abstract: A hopper for a folding unit includes a pair of spaced support surfaces for supporting sheets and intermittently actuated drive chains provided for driving the shoots along the support surfaces toward a sheet extractor, the support surfaces (46, 48) being independently adjustable to selectively vary the presentation of the sheets to the extractor and to thereby permit precise positioning of the sheets relative to the folding unit.

Title: Method for determining signal detection threshold in ESM communication system
Inventor: KING KENNETH DAVID
IPC: G01R23/16
Filed: 1990-04-11
Abstract: The invention determines the signal detection threshold for a communications ESM (electronic support measures) signal detection system operating in non-white, unspecified noise. The method adapts to changes in the noise characteristics with time. The invention detects signals for a communications ESM system given a signal spectrum and detection threshold. It has the advantage that it does not require assumptions regarding channel frequencies. It utilises intelligent clustering of signal energy to avoid false alarms due to signal sideband energy. For thresholding, a modified spectrum M(f) is formed by adding a power of the frequency to the power spectrum. In thresholding, signal components are monitored for frequency difference and amplitude, to determine whether they are sidebands of each other (Fig 6 not shown).

Title: Gravity activated fluid control valve
Inventor: EAVES MARY MARTIN
IPC: F16K21/00
Filed: 1990-07-23
Abstract: A valve automatic in operation, is arranged to allow the passage of fluid when the weight suspended from it is reduced. A two part body 1 & 2 is provided with support means 5, may be attached to a fluid container 26, and has fluid inlet pipes 11 & 12. A valve stem 3 carries a seal 8 which may be held off its seat 24 by a control spring 7. An attachment means 6 on the valve stem 3 carries a load which when equal to the strength of the control spring 7 biasses seal 8 into engagement with its seat 24. Locking of the valve in a closed condition, and adjustment of the biassing force of control spring 7 is provided by rotation of the valve stem 3 following pivoting of attachment means 6 to remove protuberance 16 from slot 15. Rotation of the valve stem 3 is prevented when a load is attached by the protuberance 16 co-operating with the slot 15. <IMAGE>

Patent GB-2239997-A (GB)
Title: Output driver
Inventor: BORKAR SHEKHAR
IPC: H03K19/0185
Filed: 1991-01-03
Abstract: An output driver for high performance integrated circuits divided into two parts: static and transient. The static part is used to maintain the DC level. The transient part is active only during logic 0 to 1 and 1 to 0 transitions and is used only to assist the static part during such transitions. The static and transient parts include main drivers 35, 37; 36, 38 and pro-drivers 41, 43, 49, 51. They operate similarly in response to an input signal transition to change the output at 19. Level detectors e.g. Schmitt triggers ST1, ST2 monitor the voltages at the gates of 37, 35 and when a predetermined threshold is reached turn off the transient part. Noise generated during logic state changes is thus reduced. <IMAGE>

Title: Programming of installation data in a cellular radio telephone
Inventor: MUKARI TIMO
IPC: H04W8/26
Filed: 1992-05-28
Abstract: Installation data for a mobile cellular telephone is installed directly in the rapid dialling memory or short code memory (SCM) 7 or other memory of the telephone. The installation data may subsequently be stored in the Number Assignment Module (NAM) 8 after temporary storage in the rapid dialling memory or SCM. The SCM locations used are invisible to the user and installation data is transferred to the NAM after an installer has effected a short keystroke sequence. The amount of memory space required to store the installation data is reduced. The SCM locations used may not be "normal" locations. To prevent misuse a protection element or its removal may be required. Installation data may be read directly from the SCM 7 without transfer to the NAM 8. <IMAGE>

An end cap (16) is disposed on one of the end panels or pivotally on the holder (14), the end cap being adapted to releasably engage the holder when the plurality of panels (12) is in the collapsed orientation, thereby to preclude accidental movement of the plurality of panels out of the collapsed orientation. <IMAGE>
Patent GB-926457-A (GB)
IPC: F25D21/00
Abstract: 926,457. Defrosting. JAMES D. WHITEHEAD & CO. Ltd. March 16, 1962, No. 10206/62. Class 29. In a system including a heat exchanger such as an evaporator for extracting heat from a region to be cooled, means such as a refrigerating system, for removing heat from the heat exchanger, heating means to defrost the heat exchanger, and an automatic defrosting control mechanism comprising a time switch, the time switch is controlled by conditions prevailing at the heat exchanger in such a manner that the time switch reaches a given position when a predetermined degree of frosting has occurred, whereupon the time switch is locked on for a predetermined defrosting period during at least part of which the cooling means is made inoperative and the heating means operative. An evaporator 3, as shown, with an expansion valve 4 at its inlet, cools an enclosure 1, and forms part of a compressor-type system, whose compressor motor M is controlled by a thermostat switch 8. The power supply to the time switch motor 17 is controlled by a switch 21 sensitive to evaporator pressure, as shown, or by a temperature-sensitive switch, so that the timer is run only when the evaporator temperature/pressure is below a preset value. The timer drives three contactor discs 14, 16, 18, having contact sectors 24, 23 and 25 respectively. Contactor 16 controls the power supply to the compressor motor M, while contactor 14 controls power supply to a defrost electric heater 12. Contactor 18 is a " lock-on " switch for the timer so that while the fixed contact 19 touches the sector 25, the timer motor is driven regardless of the setting of the switch 21. Defrosting is initiated when sector 24 comes into engagement with fixed contact 13, and is terminated either by a thermal switch 26 sensitive to evaporator temperature or by a pressure switch 28 sensitive to evaporator pressure, both these quantities rising sharply when all the front has been melted. A second system (Fig. 3, not shown) in which defrosting is by warm vapour pumped directly from the compressor to the evaporator through a by-pass line controlled by a solenoid valve, includes two timer-driven contactor discs and an electric relay control circuit.

Filed: 1994-01-27
Abstract: A clutch (10) in which a driven plate (11) is clamped between a flywheel (12) and a pressure plate (13) by a diaphragm spring (14) and in which resilient means (15) acts between the diaphragm spring and the pressure plate to clamp the clutch in series with the diaphragm spring comprises release means (20) which operates between the diaphragm spring (14) and the pressure plate or resilient means to unclamp the clutch on movement of the resilient means (15) and diaphragm spring (14) operate diaphragm spring in a clutch disengaging direction. The resilient means (15) and diaphragm spring (14) operate together so that movement of the clamped position of the pressure plate (13) towards the flywheel (12) on wear of the driven plate (11) is taken up principally by the deflection of the resilient means (15) so that the diaphragm spring retains a substantially constant clamped attitude through the life of the clutch as the driven plate wears. The means (20) includes pegs (21) with ratchet teeth (23) or (33) (Fig. 7), or a bush (53) (Figs. 9 - 12) which grips a pressure plate projection. <IMAGE>
