Patent GB-2084898-A (GB)
Title: Periodic rejuvenation of a catalyst filter
IPC: F01N3/027
Filed: 1981-09-29
Abstract: Method for filtering combustible particles from an exhaust gas stream, and for periodically rejuvenating the filter bed by incinerating retained particles. At least a portion of an engine's exhaust gas stream is initially preheated to raise the filter's catalytic segment to a pre- determined "lightoff" temperature. A supplementary fuel flow e.g. of H2, propane, diesel fuel, kerosene, or alcohol is then introduced to the catalyst segment which, being at "lightoff" temperature, will cause the supplementary fuel to react. Subsequent to the initiation of this oxidation reaction, further energy input to increase the exhaust gas to "lightoff" temperature, can be reduced or cut-off without effecting the continuing particle incineration rate.

Title: Fuel pump for I.C. engine
IPC: F04B53/10
Filed: 1982-04-16
Abstract: Fuel is supplied to the high- pressure reservoir (44) of an internal- combustion engine, to supply the injection valves (45), via a fuel path leading from the piston pump pressure chamber (9), which path includes a pressure valve (13) opened by fuel pressure and closed by a compression spring (29). The pump housing portion (3, 4, 5) to which the valve carrier (12) of the pressure valve (13) is connected, has a high-pressure buffer storage chamber (40) for reducing the harmful excess pressure peaks which occur in the fuel supplied during the working stroke of the piston pump, which chamber is connected on its inlet side via ducts (41) to a fuel collecting chamber (31) surrounding the pressure valve (13) and on its outlet side via a choke bore (42) to a fuel line (43) leading to the high- pressure reservoir (44). The pressure valve (13) has a hollow interior (37), and an abutment (30) cooperates with the pressure valve (13) to throttle the flow of fuel into and out of the chamber (37) to damp the valve movement. <IMAGE>

IPC: D04B15/48
Filed: 1982-05-12
Abstract: Yarn feeding apparatus for multi- feed knitting machines, particularly for circular knitting machines, comprising a rotatable roller or wheel 2, on which a belt 5 operates and presses thereon a yarn 8 passing between eyes carried by a yarn inserting arm 6 and a yarn outlet arm 9, such arms being movable between a position for holding the yarn between the belt and roller or wheel, and a position at which the yarn is thereby held out of contact with the belt. The apparatus comprises an eye 12, positioned between the belt and the outlet arm, which is always laterally displaced relative to the belt, and through which the yarn outletting from the apparatus passes before passing to the outlet arm. Thus, the time required for discontinuing the yarn supply by the apparatus is considerably shortened. <IMAGE>

Patent GB-2102567-A (GB)
Title: Photometer
Inventor: WITTE WOLFGANG
IPC: G01J3/42
Filed: 1982-07-02
Abstract: A double-beam photometer includes a single photometric detector which is subject to inertia. A beam switching device causes sample and reference light beams to be alternately directed upon the detector with intervening dark intervals. The theoretical square waveform is distorted as the result of the inertia of the detector to give the illustrated waveform. Thus, during each reference and sample interval the detector signal 48, 49 approaches exponentially a final value 40, 50 respectively and during the subsequent dark interval decreases again exponentially along the line 44, 45 towards the theoretical dark value 46. In processing these signals the value of the signal during each reference and sample interval has substracted from it the value of the signal from the subsequent dark interval, the signals being measured at a specific moment in each interval, i.e. tv2, t'v2, tp2 and t'p2 respectively. It is shown mathematically that, in this way, an exact compensation of the dark current is achieved in spite of the inertia of the detector. <IMAGE>

Title: Rangefinder for marked targets
Inventor: KIRKMAN PAUL DOUGLAS
IPC: G01C3/10
Filed: 1982-08-04
Abstract: In a rangefinder the field of view is observed from two laterally offset locations L and L' by television cameras which are used to determine two angular positions X1 and X2 of a laser spot. A narrow band filter E centered on the laser wavelength is used at one camera L' to remove scene details allowing the camera waveforms to be added giving a single observed scene in which two laser spots are present. The spot separation X1-X2 is then used to calculate range. One camera may be the virtual image L' of the other camera L seen via a mirror system M1,M2 which provides the offset D. <IMAGE>

Patent GB-2108718-A (GB)
Title: DC Motor control circuit
Inventor: SONODA MASAKAZU
IPC: G11B15/20
Filed: 1982-09-24
Abstract: A control circuit for a DC capstan motor used for driving a tape having control signals thereon is adapted for accurage stopping of the tape during intermittent-motion operation. A frequency generator coupled to the motor generates a frequency signal whose rate is proportional to the motor's speed. A position signal generating circuit generates a position value that increments by steps upon occurrences of the frequency signal. A clamp circuit clamps the position value to a clamping level upon detection of the control signals. A brake start signal generator provides a brake start pulse signal when the position value exceeds a predetermined threshold, and this brake start pulse signal is used to commence braking of the motor. In order to permit accurate stopping in both forward and reverse directions, the clamping circuit provides one clamping level when a forward mode is selected and another clamping level when a reverse mode is selected.

Title: Granulating cathode copper
Inventor: THOMAS SIMON DAVID
IPC: B22F9/04
Filed: 1983-04-05
Abstract: Sheets 1 of cathode copper are deformed for instance by pressing between dies, to give at least one edge (3, 4) a sinuous shape with an overall height greater than the thickness of any of the sheets. They are then fed, with that edge either leading or trailing, to a granulator of the type comprising a rotor with at least one blade co-operating with at least one fixed blade to comminute the feeding material repeatedly until the particles are small enough to pass through a screen bounding the working zone. This deformation gives the sheets a uniform effective thickness to facilitate feeding through a slot in the machine housing without jamming by over-riding of thin sheets or excessive vibration. <IMAGE>

Title: I.C. engine exhaust gas recirculation system
Inventor: LEMON DAVID SYDNEY
IPC: F02D21/08
Filed: 1983-09-16
Abstract: An exhaust gas recirculation valve 15 is actuated by an actuator 16 responsive to an oxygen sensor 19 which provides a signal representing the actual oxygen level in the exhaust gas and air mixture flowing to the engine. The signal from the sensor is compared with a desired oxygen level signal obtained from an engine test information store 20 on the basis of signals from engine speed and fuel flow rate sensors 21, 22 received by the store and the resultant signal is used to control the valve 15. Conveniently the oxygen sensor 19 is responsive to the partial pressure of the oxygen in the mixture. <IMAGE>

Title: Apparatus for limiting current through a DC motor
Inventor: GENTLE TERRENCE GEORGE
IPC: H02H7/08
Filed: 1983-09-21
Abstract: The starting or stall current through the windings of a DC motor is limited to a safe value by causing the current to flow through a reference resistor R6 and the emitter/collector path of a power transistor Q4. When the current exceeds the limit value, the voltage drop across the resistor renders a transistor Q2 conductive to draw base current from transistor Q4 and thus increase its impedance to limit the motor current to a preset value. After a chosen time of maximum current, an associated timer circuit R8, C2 causes a diode D3 to breakdown to render a transistor Q3 conductive to further increase the impedance of transistor Q4 to reduce the motor current to a very small value prior to de-energization. <IMAGE>
