Patent GB-2050198-A (GB)
Title: Production of cleaned and cooled synthesis gas
IPC: B01D45/00
Filed: 1980-05-02
Abstract: The hot raw synthesis gas stream leaving the reaction zone (2) of a free flow partial oxidation gas generator (1) at a temperature in the range of about 1800 DEG  to 3000 DEG F is passed through a first gas diversion and residue separation zone (4) where the velocity of the gas stream is reduced and its direction is diverted into a side transfer line (45). Solid material and molten slag separate by gravity from the gas stream. The hot gas stream is then introduced into a second gas diversion and residue separation zone (46) where additional residue is separated. About 0.5 to 20 vol. % of the hot gas stream may be passed through bottom outlets (30, 49) in said first and second gas diversion zones in order to prevent bridging. The hot gas stream from the second gas diversion zone is passed upwardly through a radiant cooler (65) where additional solid matter is removed by gravity and the gas temperature is reduced to a temperature in the range of about 900 DEG  to 1800 DEG F. In a second embodiment, the second diversion and residue separation zone is a thermally insulated cyclone. <IMAGE>

Title: Product surface checking
IPC: G01N21/89
Filed: 1980-05-23
Abstract: Each line of an image scan (10) is used to produce a voltage signal (a) in corresponding to image brightness along the scan line. The number of turning points in the voltage waveform is detect (48) to determine rejection (49) or not of the product. The voltage signal can be compared with two thresholds (d and g) which follow the voltage signal up and down respectively from below and above the initial voltage signal. Upper threshold level (d) is set by operational amplifier 34, diode 50 and capacator 52 in response to a maximum in signal (a). Lower threshold level (g) is set by similar components 30, 60, and 62 by any subsequent minimum in signal (a). Threshold cross- over detection (38, 26) is used to determine the second and subsequent turning points. Alternatively more than two fixed thresholds are used and the cross- over results combined. <IMAGE>

Title: Fuel Injection Nozzles
IPC: F02M61/18
Filed: 1980-06-20
Abstract: A fuel injection nozzle tip 13 has a reduced end portion 16 of a bore which carries a fuel pressure actuated valve member. Where a symmetrical spray pattern is required but where it is not possible to mount the nozzle so that the axis 26 of the bore coincides with the cylinder or combustion chamber axis, the orifices 27,28 can be drilled at the required angle but the contour at the points of exit from the born 16 would not be the same.

Title: Electromagnetic device
IPC: H01F3/14
Filed: 1980-10-09
Abstract: An electromagnetic device includes a stator having axially spaced pole pieces 12 and windings 14 which when energised cause adjacent pole pieces to have opposite magnetic polarity. An armature 11 surrounds the stator and is of tubular form having a smooth internal surface. The exterior surface of the armature is machined such that at least at one end of the pole pitch distance of the stator the thickness of the armature is such that magnetic saturation of the material forming the armature occurs so that the lines of force between the armature and the pole piece extend in a direction inclined to the axis of the armature thereby resufting in a force acting to cause axial movement of the armature. The armature moves against a spring or other device so that armature is restored to original position when current ceases. <IMAGE>

Title: Control system for a fluid pressure engaged clutch
Inventor: YOUNG ALASTAIR JOHN
IPC: F16D48/02
Filed: 1982-06-03
Abstract: A hydraulic pressure control valve (15) for a fluid pressure operated clutch (18) includes a piston (21) responsive to a pilot control pressure at 24 as a proportion of source pressure and feedback pressure at 19 indicative of fluid pressure in the clutch to connect the clutch to source pressure whenever pilot pressure exceeds feedback pressure and to connect the clutch to drain (22) whenever feedback pressure exceeds pilot pressure.

Patent GB-2124956-A (GB)
Title: Electro erosive machine tool
Inventor: BECKETT MICHAEL JOHN
IPC: B23H7/18
Filed: 1982-08-03
Abstract: An electro erosive machine tool has an electrode position setting member 18 which moves to present a flat surface 20 to the ends of machining electrodes 12 for the purpose of aligning the electrodes 12 and setting them to a datum. Sometimes, an electrode 12 projects beyond the flat surface 20 and a collision results, which bends the electrode. If the event is not noticed, the machine tool will continue the sequence of operations with the result that the bent electrode will machine a groove in the workpiece 14. In one embodiment of the invention, an electrical circuit 28 is closed on such collision occurring and a relay 32 consequently breaks the primary circuit of the machine and so disables it. In a further embodiment of the invention the collision triggers a monostable and a microprocessor which scans the operation of the machine tool, observes the trigger pulse and instructs the electrical disablement of the machine tool. <IMAGE>
