Patent GB-2237372-A (GB)
Title: Air conditioning systems
Inventor: ATKINSON MICHAEL JOHN
IPC: B60H1/00
Filed: 1989-10-10
Abstract: A compact, exhaust gas driven air cycle air conditioning system comprising a compressor (12), turbine (16), two heat exchangers (14, 18) and an exhaust turbine (40) is controlled by means of an exhaust gas bypass arrangement (42) and supplies either hot or cold (as shown) conditioned air, as required, to a load air space (26). Switching between cooling and heating modes is implemented using two-way valves (22, 32) such that the same components may be used, and in all embodiments described the conditioning air is supplied from a dry, closed loop. The system may operate in reverse flow i.e. the working air enters the turbine (40) first. Moisture removal devices (34, 34') may be incorporated to avoid heat exchanger icing and also control humidity. In addition, de-icing systems arc included in the reverse flow embodiments because of their greater susceptibility to heat exchanger icing due to lower cycle temperatures. The temperature at which air is delivered to the load may be controlled by diverting amounts of hot or cold air, as appropriate, to be mixed with the conditioning air. A high speed motor may be included for use as an alternative to the exhaust gas drive under conditions of low exhaust gas energy. <IMAGE>

Title: Seat belt reel with emergency locking and auto locking modes
Inventor: JABUSCH RONALD
IPC: B60R22/415
Filed: 1991-02-08
Abstract: A seat belt reel has an emergency locking mode and an automatic locking mode. The emergency locking mode is conventional and responsive to vehicle deceleration. The automatic locking mode comes into effect when the belt is substantially fully unwound. At this point a pawl lever 20, 21 is urged by spring 22 into engagement with ratchet teeth on the reel so as to prevent unwinding of the belt, although owing to the ratchet action it can be allowed to rewind to engage eg a child's safety seat. When the belt is fully rewound, the projecting lever 19 is engaged by the belt and causes disengagement of the pawl from the teeth, thus allowing the reel to assume its normal emergency locking mode. <IMAGE>

Title: Ic engine multi-spark ignition system
Inventor: VAUGHAN MARK CYRIL VINCENT
IPC: F02P3/04
Filed: 1991-03-08
Abstract: When a single pulse from the input driver 22 is fed through the Schmidtt detector 23 into the multi-spark frequency modulation oscillator 27 it is converted into a series of pulses which are fed through the power MOSFET driver 28 into the power MOSFET output stage where each pulse causes the primary windings of the ignition coil to be energised producing a series of sparks. The Schmidtt detector also provides signals for a static timing indicator 24, a tachometer output driver 26 and a no run clamp 25 which disables the MOSFET driver 28 when the engine is stationary. <IMAGE>

Title: Method of and apparatus for the detection of misfires in an internal combustion engine
Inventor: KLENK MARTIN
IPC: F02B77/08
Filed: 1992-01-10
Abstract: A method for the detection of misfires in an internal combustion engine of a vehicle comprises the step of discontinuing the detection after the appearance of predetermined conditions until those conditions are no longer fulfilled. These conditions can include purely logical conditions, travel state conditions and operating conditions. In the case of a logical condition, further detection of misfires can be prohibited for a preset number of ignition cycles. An example of a travel condition is that of vehicle travel over bumpy ground. Operational state conditions include rapid changes in load or rotational speed or very high or very low rotational speeds. The method is stated to give good accuracy of misfire detection without a large computing effort. As described misfire is detected from variation in the time interval for a piston to pass two sensors situated respectively before and after top dead centre, or by a knock sensor.
Patent GB-2253949-A (GB)
Title: Radio antennas
Inventor: BOTTOMLEY HOWARD FRANK
IPC: H01Q1/08
Filed: 1992-01-17
Abstract: A radio antenna has an antenna element 12 which is slidable with respect to a casing of the radio between an extended position and a retracted position. In the extended position, a metal plate 15 on the lower end of the antenna element 12 cooperates with a fixed dielectric 17 and a fixed metal plate 16 to form a capacitor providing a signal link to a coaxial cable 18 leading to a matching network. This avoids the need for a sliding metal connection, as in the prior art. In the retracted position of the antenna element 12, the capacitative link is effectively disconnected. Alternatively, the antenna element may be pivotally movable. <IMAGE>

Abstract: A heating system for domestic hot water comprises a thermostatically controlled boiler (2) provided with flow and return connections (R, F) for the passage therethrough of primary water, a thermal store (6) including a water-containing volume having an inlet connected to the flow connection (R) of the boiler (2) and an outlet connected to the return connection (F) of the boiler (2), and a heat exchanger (10, 12) housed within the thermal store (6) and through which passes secondary water to be heated by heat exchange from the primary water. The boiler thermostat (4) monitors the temperature of the water at or adjacent the return connection (F) of the boiler (2) such that activation of the boiler (2) is under the control of the thermal store thermostat or the temperature of the primary water returning to the boiler (2) from the thermal store (6). As shown the normal flow and return boiler connections are interchanged so that the thermostat (4) senses the return water flow. The thermal store has central heating and store thermostat 22 and 20, the latter being set to operate at the same temperature (82 DEG C) as the boiler thermostat. <IMAGE>

Title: Vertical pump with magnetic coupling.
Inventor: WOLBERS BERNARD RUDOLF
IPC: F04D15/00
Filed: 1993-01-14
Abstract: The inner rotor 4 of the magnetic coupling is coupled to the drive shaft 3 and the outer rotor 5, separated therefrom by a separating pot 8, is coupled to the shaft 7 supporting the pump member. The construction of the pump is hereby greatly simplified. Any danger of the bearings being left dry during starting of the pump is avoided. By connecting the delivery side of the pump (line 14) to the space 13 enclosing the outer rotor 5, sufficient liquid is always supplied to this space and therefore to the bearings which may be ceramic. Air bubble formation can be avoided by connecting this space to the atmosphere via a venting valve 20. <IMAGE>

Patent GB-2290440-A (GB)
Title: Mains borne signalling system
Inventor: TELCO PAUL
IPC: H04H20/84
Filed: 1995-06-16
Abstract: A system comprises a controlling transmitter and one or more interactive receivers, which stations communicate with one another via the mains cabling. On installation, the controlling transmitter monitors any signals already present on the mains to check which system codes, if any, have already been allocated to other systems within range of the system. As a result of this monitoring, the controlling transmitter allocates an unused system code for the system. Thereafter, each receiver is provided with this system code and a channel code associated with that receiver. An additional feature of the present system is that collisions at the time of installation are prevented as a result of the controlling transmitter checking for the presence of any other programming codes before transmitting a programming code itself.

Title: Self phased antenna element with dielectric
Inventor: THILL KEVIN MICHAEL
IPC: H01Q1/24
Filed: 1996-03-25
Abstract: A self phased antenna element with two pairs of arms 110, 120, 130, 140 in a crossed relationship transceives a signal at a resonant frequency. A dielectric 150, 160 is disposed adjacent or touching an arm 130, 140 to obtain a self phased relationship in the arms 110, 120, 130, 140 at the resonant frequency. The arms can form crossed loops (fig 8) or twisted crossed loops such as a quadrifilar helix antenna element. A dielectric collar 150, 160 on arms of the same loop causes arm currents to be equally spaced from one another. The antenna size is reduced and a cross section of the antenna element appears circular without degradation of a gain pattern when the dielectric is used on the certain arm. Dielectric members (520, 530, 540, 550, fig 5, 6) may be molded into the sides (513, 515, fig 5, 6) of a radome.
