Title: Method and apparatus for continuously producing and recovering metallic chlorides
IPC: C01G49/10
Filed: 1974-01-03
Abstract: 1455310 Metallic chlorides L E NICKEL 3 Jan 1974 60092/73 Heading C1A [Also in Division C7] Metallic chlorides are continuously made by melting a stream of a metallurgical material, e.g. a matte or impure metal, passing the melt into a pool into which gaseous Cl 2  is injected, removing the vapourous metallic chloride(s), diluting the vapour with a cooling gas to condense the chloride(s), separating the solid choride(s) from the cooling gas and continuously cooling and recycling the cooling gas. The cooling gas may be S vapour and the continuous cooling preferably condenses vapour to liquid which is then evaporated and recycled. When a matte, e.g. Ni matte is treated, a portion of S coolant corresponding to S in matte is removed prior to recycling. A suitable plant comprises a furnace 1 separated from a chlorination chamber 2 by a wall 8 having an orifice 9 permitting the melt to flow from the furnace to the chamber. Cl 2  is injected into the melt through pipe 11 and vapourous chlorides are led away in duct 14 to a condensation chamber 15. Cooling gas is introduced through duct 19 and leaves through duct 24 whereafter it is cooled and recycled.

Abstract: 1,245,656. Shaft couplings. FRIEDMANN & MAIER. 23 Dec., 1968 [22 Dec., 1967], No. 61060/68. Heading F2U. An adjustable shaft coupling (e.g. driving a fuel injection pump actuating cam-shaft) comprises an axially movable (e.g. due to centrifugal motion of weights 6 against springs 14, 15) internally splined sleeve 8 in mesh with two gears 2, 3 of which one at least has helical teeth 9, one or both gears 2, 3 having ratchettype teeth 13 transmitting torque via the teeth backs 12.

Patent GB-727518-A (GB)
Abstract: 727,518. Clocks. TIRKAS, K. J. Dec. 23, 1952, No. 32531/52. Class 139. [Also in Group XIX] An apparatus for timing a runner or winning runner of a race comprises a spring-driven lever escapement type stop watch to which are added two electrical circuits, one being a starting circuit for setting the watch mechanism in motion by the closing of said starting circuit and the other being a stopping circuit for interrupting the watch movement by the breaking of said stopping circuit, said starting circuit being adapted to close automatically upon the firing of'a starting pistol and said stopping circuit being broken by severing of a wire tape in the stopping circuit by the runner or winning runner of the race. In the first example, as the trigger of a starting pistol 30, Fig. 3, is pulled the contacts 31, 32 meet to close the circuit from a battery 29 to an electromagnet 13, Fig. 1, on the watch case 11. The electromagnet 13 is thereby energized to move its armature 14 against the pressure of a spring 15 so that a rod 16 is moved to free a locking lever 21 from the escapement lever 23 and the watch starts, the lever 21 being retained by a clip, not shown. An electromagnet 17 is normally energized, through a circuit including the finishing wire tape, and its armature 19 is therefore normally raised. When the finishing wire tape is broken by a runner the electromagnet 17 is de-energized whereupon its armature 19 falls by gravity and its leg 20 resets the lever 21 into locking engagement with the escapement lever 23 to stop the watch. The pistol 30, Fig. 3, may be replaced by a signal transmitter comprising a rod 25, Fig. 2, having a housing 26 containing a fixed carbon or copper block 27 and a movable copper foil 28. The foil 28 is moved by air pressure upon firing of the starting pistol to abut the block 27 and close the circuit to .the electromagnet 13 from the battery 29.

The field oxide masks the surface during the implantation of the source and drain 13 and 14 of the devices. In a variant a photoresist layer is used to mask etching of oxide layer 2 to define the field oxide, a gold layer evaporated overall and lifted-off where it overlies the photoresist to define a mask for implantation of the stoppers. <IMAGE>

Title: Improvements in or Relating to Addressable Matrices
IPC: G09G3/36
Filed: 1979-04-17
Abstract: An addressable matrix consists of an array 9 of addressable elements, e.g. liquid crystal, which are defined by the crossing regions of row 8 and column 10 electrodes. The state of an addressable element, dependent on on the rms potential across the element, is related to the magnitude of electrical signals applied to row and column electrodes and to the number of elements in the matrix. The magnitude of the electric signals is modified according to the number of elements in the matrix which are currently being addressed to be in the ON state, allowing the operating margin between ON and OFF potentials to be maximized. N columns are scanned, being energized in succession while the states of the N elements displayed in each row are prestored and circulated in a register 3 for that row. A count 4 of ON elements in each register, i.e. 1 bits, determines via a circuit 5 the voltage levels for ON and OFF to be applied to the row electrode at 6 according to each bit in the register, operating selector 7 as each column in turn is scanned. <IMAGE>

Title: Vehicle speed detectors
IPC: G01S13/92
Filed: 1979-08-10
Abstract: The vehicle speed detector has a transmit antenna A1 driven by a modulator MOD by way of a GUNN diode source GDS. Vehicles approaching the detector generate particular frequency signals at specific distances from the detector which are received by a receive antenna A2 and fed by way of a mixer M to filter networks F2, F3, F4 which filter particular frequencies related to the specific distances. The filtered signals are fed to respective phase lock loop circuits PLL1, PLL2, PLL3 which provide output signals, the rates of change of which, as determined by differentiating circuits D1, D2, D3, are directly proportional to the vehicle speed. The output signals are fed to respective threshold circuits TH1, TH2, TH3 and speed classification circuits S1, S2 ,S3, the latter being activated only during the positive going output from the respective phase lock loop circuit so that vehicles travelling away from the detector are discriminated against. <IMAGE>

Patent GB-2032149-A (GB)
Title: Transferring from Working to Standby Processor on Fault
IPC: G06F15/16
Filed: 1979-08-30
Abstract: A multi-processor system includes at least a first processor and a second processor one of which performs data processing of successive processing steps. The processing processor transfers result data to the other processor each time a data processing step is completed, and the latter processor stores the transferred resultant data. Programs are segmented by respective predetermined breakpoints for a job. When the processing processor is in an abnormal condition, the other processor takes over the job from the nearest breakpoint by utilizing the last transferred result data. The arrangement requires a simpler interface than a fully duplicated redundantly operated system whilst providing rapid transfer when a fault occurs.
