IPC: F02M1/04
Filed: 1979-03-02
Abstract: An i.c. engine has diaphragm fuel pump 14 incorporated in the body of an automatic choke. The volume of control chamber 68 is controlled in accordance with engine temperature and the depression in it is limited by a mechanism comprising a beam 96 which rocks on the diaphragm 71, a control rod 97 which is pivotally connected to one end of the beam 96 and which has its location within the chamber 68 controlled by the thermostatic mechanism of the cold start device in accordance with engine temperature, and a suction port shut-off valve 95 which is spring seated on the other end of the beam 96. A clearance between the rod 97 and a bore 99 in which it slides provides a restricted air bleed into the chamber 68. The suction port is connected to the engine inlet manifold. <IMAGE>

Patent GB-2034965-A (GB)
Title: Electron beam focussing in X- ray tubes
IPC: H01J35/14
Filed: 1979-09-10
Abstract: The invention relates to a conical (e.g. part conical, or bell shaped) x-ray tube for which there ion are problems focussing the electron beam over a long throw, typically 1.5 metres. It is proposed to achieve focussing by the use of a double conical coil system (17, 18) inside and outside the conical envelope (1). This will usually result in successive refocussing of the beam in a series of loops to the target passing through successive nodes of focus. Preferably the beam is incident on the target at or close to a node. Tilting of the field in the rear of the tube to align with the direction of the electron beam in the conical section is provided by a saddle coil arrangement described w.r.t. Figs. 7, 8 (not shown), magnetic insulation being optionally provided around the bridging sections. The system of coils is further detailed in Fig. 9 (not shown). Defocussing due to space charge dispersion is discussed. The envelope may be non-magnetic metal (eg stainless steel). The beam cross-section at the target may be circular but is preferably line shaped and maintained radial to axis (7) by tube rotation or a rotating field system. Collimators (10) are included (Fig. 1, not shown). Dimensions, potentials, currents, and magnetic field intensities are exemplified. <IMAGE>

Title: Capacitance frequency modulation probe for blade tip clearance measurement
IPC: G01B7/14
Filed: 1980-03-12
Abstract: A gas turbine engine casing (10) is provided with a probe (12) having an electrode (16) which is adapted to cooperate with the tips (22) of successive rotor aerofoil blades (11) to define a series of capacitors, the capacitances of which are proportional to the clearance between the blade tips (22) and their surrounding casing (10). The thus formed capacitors constitute the frequency determining elements of the tuned circuit of an oscillator (23), the output frequency of which is consequently a function of the blade tip clearances. The output of the oscillator is connected to a guard electrode (21) within the probe (12) so that capacitance effects within the probe (12), other than those resulting from co- operation between the probe electrode (16) and blade tips (22), are substantially eliminated, by ensuring that the guard electrode (21) and lead (17) to electrode (16) are substantially at the same potential. <IMAGE>

Patent GB-2059722-A (GB)
Title: Satellite communication system
IPC: H04B7/00
Filed: 1980-09-17
Abstract: In a satellite communication system a ground station transmits an information carrying plane polarised signal to the satellite where it is broadcast to a number of individual receivers on the earth. The effect of the earth's atmosphere partially depolarises the plane polarised signal and to provide compensation for this effect, the earth station transmits simultaneously with the information carrying signal an additional plane polarised signal, which is polarised at right angles to the first signal so as to provide forward correction for the de-polarising effect. The additional signal is arranged to cancel the cross-polar components of the de-polarised signal produced within the atmosphere. A number of methods are described for determining the properties of the additional signal which are necessary to achieve compensation.

Title: Machine for sheathing articles in an initially flat gusset- folded flexible tube
IPC: B65B9/13
Filed: 1980-12-16
Abstract: The machine comprises a chassis 1 having a four pillars 2 in which a rectangular frame 10 is vertically slidable. A stack 5 of articles can be located within the chassis by a conveyor 3. The flat-folded tube 6 is fed downwardly by rollers 7 and encounters retractable wedges 9 on opposite sides of the frame 10, the wedges 9 entering the gusset folds to separate their adjacent faces. Four roller clamps 17 each comprise two rollers and are slidably mounted in pairs on opposite sides of the frame 10. The clamps can each be actuated to grip the tube 6 between the two rollers which form the clamp, and the clamps of each pair can be slid apart to spread the tube 6 and to permit its open bottom edges to be gripped by devices 11 which can move downwards on the pillars 2 to draw the tube 6 through the rollers of the clamps 17 and over the stack 5. Before completion of the downward movement of the devices 11 the wedges 9 are withdrawn from the tube path to cause the top end of the tube to be stretched horizontally over the stack 5. The frame 10 and devices 11 then move down in synchronism and the clamps 17 are finally disengaged from the tube 6. <IMAGE>

Title: Apparatus for Continuously Monitoring the Air Pressure in Vehicle Tyres
IPC: G01L17/00
Filed: 1980-12-17
Abstract: An apparatus for monitoring the air pressure in the tyre of a vehicle wheel comprises a magnetic field producing device 6 which is fixed to the vehicle wheel and rotates with it. An induction loop 7 is positioned at a fixed location on the vehicle adjacent to the wheel and is subjected periodically to the magnetic field of the magnetic field producing device as the latter moves past it. The magnetic field is produced by passing an oscillating signal through a coil 5, this signal being generated in a resonant LC circuit whose oscillating frequency is determined by an impedance, such as an aneroid capacitor capsule 3, which varies in dependence upon the air pressure in the tyre. The coil 5 can be part of the resonant circuit 6 or can be fed by a separate oscillator, such as a multivibrator. Energy for energizing the device can be supplied electromagnetically from a fixed transmitter to an energy pick-up on the wheel. <IMAGE>

Title: Benefication of coal by polymer coating the particles thereof
IPC: B03D3/06
Filed: 1981-01-14
Abstract: An improved beneficiated coal product is disclosed comprising coal particles which have been rendered hydrophobic and oleophilic by forming a polymer coating thereon. According to the process an aqueous slurry containing the coal particles is admixed with a fuel oil and a polymerisation mixture preferably containing one or more long chain carboxylic acids which are polymerised in situ on the coal particles. The hydrophobic coal particles are then separated from the aqueous medium by froth flotation preferably in several steps by atomising the flocculated coal particles onto the surface of a mass of wash water. Hydrophilic ash particles separate into the wash water whilst the flocculated hydrophobic, oleophilic coal particles are recovered. Following recovery the flocculated particles are de-watered mechanically. Additional but optional treatments include neutralisation and admixing with oil to form coal-in-oil mixtures, and subjecting the particles to a second graft polymerisation procedure.
