Patent GB-2262811-A (GB)
Title: System for measuring fluid flow
Inventor: TOLEMAN BERNARD JOSEPH
IPC: G01F1/684
Filed: 1992-12-23
Abstract: A system for measuring fluid flow, e.g. in an air duct 10, comprises a first sensor 16 adapted to produce an output signal dependent on the temperature of the fluid, and a second sensor 18 which is disposed in the flow path of the fluid. The second sensor 18 includes a temperature responsive integrated circuit device 23 and a heater 24 located adjacent thereto, and produces an output signal indicative of the resultant temperature due to the heating effect of the heater and the cooling effect of the flow of fluid past the second sensor. The signals from the first and second sensors are processed to produce an output indicative of the rate of fluid flow. As shown the sensor 18 comprises an aerodynamically shaped pod 22 containing paste 23 to provide thermal coupling between the heater and temperature responsive device. The pod is mounted on a transverse strut 17 attached to a frame 13 intended to be bolted between two duct sections. A display 20 shows both temperature in the duct and flow rate. <IMAGE>

IPC: F25B49/02
Filed: 1992-12-31
Abstract: To detect abnormal operation of an expansion valve 1, the number of excitation pulses to the stepper motor 14 of the valve 1 are counted 17 and compared 18 to the measured number of pulses 16 representing the actual movement of the valve. Abnormal operation is determined when the two counted pulse numbers differ. The movement detector may comprise a Hall element (11, figure 5) that produces an EMF dependent on the movement of the magnetic core (5, figure 5) of the valve drive, the output of the Hall element being amplified 13 and rectified 15 to produce a pulsed signal. <IMAGE>

Title: Vectorable nozzle for an aircraft
Inventor: YATES MARTIN HAMPDEN
IPC: F02K3/02
Filed: 1993-03-13
Abstract: A vectorable nozzle 1 for a vertical lift aircraft comprising an array of lift flow deflecting vanes mounted in a frame 32 hinged to an undersurface of the aircraft. The nozzle is formed by a plurality of telescopic shroud members 2 to 9 which together with the vane frame are mounted at their forwardmost ends. The disposition of the vanes is such that the lift flow is directed downwards when the nozzle is extended (as shown in Fig 3). When the nozzle is retracted the flow is vectored rearwards to provide forward thrust. In this position the nozzle generates minimum aerodynamic drag from forward movement of the aircraft. The nozzle preferably is fully stowed within the aircraft, and concealed by surface doors when not in use.

IPC: H04B7/26
Filed: 1993-09-23
Abstract: A dual mode cellular cordless portable radiotelephone (101) preferentially selects the cordless base station (115) over the cellular system (103) when in range of the cordless base station (115).

Title: Electrical connector with reduced crosstalk
Inventor: PINNEY DAVID RALPH
IPC: H01R13/6467
Filed: 1993-12-03
Abstract: An electrical connector has four contacts (3, 4, 5, 6) extending between input terminals (12) and output terminals (13). In order to reduce crosstalk between signal carrying pairs (3, 6/4, 5) of contacts there is provided an overlapping of the mutually most distant contacts (3 and 5/4 and 6) of the different pairs to provide capacitive coupling therebetween and thereby induce crosstalk in opposition to crosstalk induced between the mutually closest contacts (3 and 4/5 and 6). The contacts are formed as two lead frames superposed and sandwiching a dielectric (17), overlapping regions being defined by widened lead portions. Alternatively, the contacts are etched or printed on the major faces of a pcb or dielectric film. Overlaps are also provided between other contact pairs such as (1, 2/3, 6). Contact terminals (12) are bent and supported in slots in a connector housing, while terminals (13) constitute id slots. Id is effected by a hinged housing lid closed by insertion into a plastics or screening outer housing. <IMAGE>

Patent GB-2283545-A (GB)
Title: Improvements in or relating to continuously-variable-ratio transmissions
Inventor: FELLOWS THOMAS GEORGE
IPC: F16H37/02
Filed: 1993-08-11
Abstract: A continuously-variable-ratio transmission ("CVT"), especially of the toroidal-race rolling-traction type, in which the prime mover is connected to the ratio-varying component ("variator") by a torque converter (1) or other starting device capable of slip. The CVT output (36) is connected both to the variator output (23) and also, by way of fixed ratio gearing (37, 38) and a one-way clutch (53), to the output of the starting device. At low speeds drive is transmitted from primer mover to the CVT output by way of the fixed ratio gearing in both forwards and reverse. In forward drive, as the speed of the variator output rises, operation of the one-way clutch (53) causes the drive transmission path to change from the fixed ratio gearing to the variator output once the speed of the latter exceeds the former. Where the variator is of the toroidal-race type, further one-way clutch means (54) may be included to ensure that the fixed ratio gearing components can rotate in one direction only, thus preventing them from imposing reverse rotation upon the essentially unidirectional variator components. <IMAGE>

Abstract: A safety keg assembly comprises a keg including a keg neck, and a safety spear valve adapted to be sealed in the keg neck by sealing means and having a valve body, the outer wall of the valve body confronting the inner wall of the keg neck when the safety spear valve is in position, a key on one of the valve body or the keg neck, and a keyway for receiving the protrusion in the other of the valve body or keg neck, the keyway (4) comprising an opening (3) allowing the key to enter the keyway, a first recess (5) in the keyway axially spaced from the opening and into which the key may be positioned by circumferential and axial movement of the spear valve to allow the spear valve to be sealingly positioned in the keg neck, and a second recess (10) in the keyway axially aligned with the first recess (5) whereby, if pressurized gas is present within the keg when an attempt is made to release the spear valve, the key will move from the first recess to the second recess by means of the residual pressure preventing angular movement of the spear valve assembly and the seal between the spear valve and the keg neck will be broken, allowing simultaneous venting of the residual pressure. The keyway may be configured as a screw thread.
