Title: Fuel control system for gas turbine engine re-heat system
Inventor: SMITH TREVOR STANLEY
IPC: F02C7/236
Filed: 1986-05-15
Abstract: The system includes a metering unit comprising a plurality of valves 250, 251, 252 for metering fuel to respective reheat burners of a gas turbine engine and a plurality of throttle valves 271, 280, 281 in series with the respective valves 250, 251, 252. One of the throttle valves 271 regulates pressure difference across its associated metering device 250 and the remaining throttle valves 280, 281 maintain the pressure difference across the devices 251, 252 equal to that across the device 250. In a particular embodiment the system includes a fuel supply valve 222 responsive to a pressure signal controlled by two of the metering devices 251, 252 so that fuel supply from a pump 220 is provided only when both of the metering devices 251, 252 are open. In a further embodiment (fig.4, not shown) a supply pump (20) includes a throttle (24) for regulating pump outlet pressure in response to the highest of the pressures downstream of the metering unit. The throttle (24) is also responsive to a pressure signal controlled by a shuttle valve (118) which is acted on by pump delivery pressure, the arrangement regulating pump delivery pressure so as to maintain metering pressure differences constant.

Title: Optical sensor device
Inventor: BATCHELDER DAVID NEVILLE
IPC: G01N33/543
Filed: 1987-10-30
Abstract: An optical sensor device uses surface plasmon resonance to detect the presence of a specific material e.g. antigen in blood. A transparent body 12 is coated with a thin gold film 14 which film may be coated e.g. with an antibody material. A divergent light beam is internally reflected at the face coated with the gold film to a photodiode array 16. The dielectric conditions adjacent the gold film 14 determine the reflection angle(s) at which surface plasmon resonance resonance in the gold film reduces the intensity of reflected light to produce a dark band(s) on the otherwise uniformly illuminated detector array 16. The intensity at each detector in the array is determined, a polynomial corresponding to the light intensity distribution is calculated, and the angle of reflection for which the reflected light is a minimum is determined from the polynomial. <IMAGE>

Patent GB-2227824-A (GB)
Title: Apparatus for dispensing drinks
Inventor: PAXMAN PAUL ANTHONY
IPC: B67D3/00
Filed: 1988-11-12
Abstract: A wine dispenser 1 comprises an enclosed cabinet 2 at the bottom of which there is mounted refrigeration apparatus 3. At the top of the cabinet 2, mounted upon a support 16, are four boxes of wine 17, each containing a collapsible bag and an outlet tap 18. The refrigeration apparatus 3 supplies refrigerant to an evaporator coil which is disposed within a product tank 10, through which coil coolant is continually circulated. Three product coils are located in the product tank 10, and each receives wine via a respective pipe 19 from a respective one of the three rightmost wine boxes 17. Each of the product coils 11 has a respective outlet tap 15. In use, wine from the three rightmost boxes 17 is drawn off through the respective taps 15, and is cooled during the dispensing action through the respective product coils in the product tank 10. The wine boxes 17 may readily be replaced and, even if they are at room temperature, the wine may be consistently dispensed at the desired chilled temperature. The leftmost wine box 17 has its outlet connected directly to a separate tap 20 by a pipe which by-passes the product tank 10, so that the wine may in this case be dispensed at a higher temperature - for example, room temperature. Drinks may also be heated using a heated product tank. <IMAGE>

Title: Measurement of flow velocity and mass flowrate
Inventor: WATT JOHN STANLEY
IPC: G01F1/74
Filed: 1989-06-01
Abstract: Methods and apparatus are provided for measuring liquid flow velocity and mass flowrates of a multiphase flow containing at least two liquid phases. Time varying measurements indicative of the ratio of mass absorption coefficients of the components of the flow at two spaced apart locations are cross correlated to determine liquid flow velocity. The time varying measurements are provided by measuring the intensities of gamma-rays transmitted through a selected volume of the flow at two different gamma-ray energies. At least one of the gamma-ray energies has substantially different mass absorption coefficients in each of the two liquids. Gas velocity, when gas is present, and component fractions of all components are determined using a dual energy gamma-ray transmission technique and with the liquid flow velocity are used to derive mass flowrates.

IPC: H04L12/54
Filed: 1992-03-23
Abstract: In a telecommunications system where a node has to send a message through a packet switched network which is of a length greater than the maximum packet size, the message is divided into smaller packets which are sent individually through the network. The packets may be sent by what is known as a connectionless service where each packet is treated independently. It is proposed that the packets are sent by a method of transmitting variable length messages on a telecommunications network from a source to a destination via an ATM or DQDB switch in fixed length cells or slots which include a header field and a payload field wherein the method includes providing a segment type field, a sequence number field and a message indentifier field in the payload field and wherein the routing information is obtained without use of the Virtual Path or Circuit Identifiers.

Title: A device for use in detaching hypodermic needles
Inventor: LANDSBERG ERROL ARTHUR
IPC: A61M5/32
Filed: 1992-04-15
Abstract: A device 10 for facilitating removal of a used hypodermic needle 62 from a syringe body 56 has a hollow base 12 on a repository 52 and defines a stripping zone having an axis 33. An aperture 25 in the base provides a narrow entrance for the needle 62 into the stripping zone. A parting member 32 is laterally movable into and out of the stripping zone. It has a bifurcated parting formation 48 which is wedge-shaped in respect of its thickness. With a needle in the stripping zone, the member 32 is displaced toward the axis 33 so that the bifurcated parting formation straddles the needle or connection means between the needle and the syringe body. Continued displacement wedges a push on needle off the syringe body. For a screw type needle-syringe assembly, the parting formation holds the needle against rotation to allow the syringe body to be unscrewed. <IMAGE>
