Title: Improvements in or relating to match delivering and igniting devices
IPC: A24F27/20
Filed: 1932-11-21
Abstract: 399,668. Match-striking appliances. HANDELSHAUS VOSS GES., 27, Neuk÷lln, Berlin. Nov. 21, 1932, Nos. 32921 and 32922. Convention dates, Nov. 21, 1931 and May 28, 1932. [Class 50.] A match delivering and igniting appliance in which each match is ejected by a slide and its head rubbed along a friction surface provides individual recesses or the like in a carrier each with a particular section of the friction surface allocated to it. The carrier may comprise a rotary channelled member set and reset in relation to a common slide for all the matches, the friction surface also being adapted to be moved therewith. Or, as in the form shown, the carrier is stationary and either each match has a separate slide 16 or a common slide is moved along the carrier. The container 1 houses a row of channels 3 on each side of a partition 2, springy parts 6 or tongues 6<1> in the walls 4 bearing against the match stems. A wedge 8 grooved at the top to engage a rail 9 carries on each inclined face a frame into which a friction surface strip 10 is inserted and an adjusting screw 11 enables the wedge to be moved slightly to provide a new surface after wear. An alternative construction embodies two resilient walls from which the wedge is drawn out in stages. Each slide 16 is guided within a slot 15 by a button 17 and extends under a match when the container is closed. A transverse bar 22 at the top of each row of channels presses on a match as it is ejected and forces it against the friction surface whilst preventing sparks from reaching the other matches. Spring flaps 6<11> may however be provided for this purpose. The friction strips may be longer than the carrier, the spare portions being rolled up at each end and used when required. Another embodiment comprises a rotatable cylindrical carrier with peripheral channels and a superposed roller coated or wrapped with friction material and adjustably coupled thereto. Or the carrier may consist of an endless band with channel-forming lugs thereon, an endless band of friction material being mounted above it and cleaned by a rasp, knife, or roughened wheel. A benzene-soaked pad or the like may alternatively be pressed on to the friction member.

Title: Torque wrenches
IPC: B25B23/142
Filed: 1975-08-07
Abstract: 1466501 Torque wrenches TOHNICHI MFG CO Ltd 7 Aug 1975 [7 Aug 1974] 32958/75 Heading B3N A torque wrench comprises a torque applying head 1<SP>1</SP> pivoted to a member 2<SP>1</SP> attached to, or as shown, serving as a handle. Pivoting of the head is inhibited by means of a spring-biased toggle linkage comprising two links 4<SP>1</SP>, 5<SP>1</SP> pivoted together and, as shown, to the head 1<SP>1</SP> and a thrust member 11 connected to the adjustable biasing spring 13 via shore 12. The arrangement is such that a two stage "breaking" action takes place at a torque predetermined by adjustment of the spring, the first breaking stage taking place at the said torque and the second at the same or a lower torque, thus minimizing the overload which can occur in single toggle link type wrenches due to inertia overrun. In Fig. 4, link 51 pivots first until its flank engages an abutment face 8 on link 4<SP>1</SP> after which the links act together as a single link to provide the second stage. In a modification, Fig. 8 (not shown), the roller on member 11, which in the previous case runs on a level path on the inside surface of handle 2<SP>1</SP>, rides up one side of a step, ramp or projection during the first stage and down the other side during the second to ensure a breaking action at a lower torque in the second stage. Other arrangements are said to be possible, by adjustment of the link angles α and # wherein to provide the two stages, the links act separately, or together then one only, or one only then together.

Title: Improvements relating to radar equipment
Inventor: MCQUEEN JACK GORDON
IPC: G01S13/62
Filed: 1964-08-14
Abstract: 1,118,991. Radar. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 12 Aug., 1965 [14 Aug., 1964], No. 33232/64. Heading H4D. A Doppler radar is provided with means whereby the sense of a target's radial motion may be determined. In the pulse radar shown, echoes are passed to one each of the inputs of phase-sensitive detectors 4 and 5. A reference signal for the detectors is provided by a synchronous oscillator 3 (synchronized by gated signals from the transmitter) feeding its output directly to detector 4 and via a 90 degrees phase shifting device to detector 5. The Doppler frequency outputs of the detectors are in phase quadrature, that from detector 4 leading or lagging that from detector depending on the sense of the target's radiant motion. The Doppler outputs are therefore fed, via range gates 7 and 8, boxcar circuits 9 and 10, and lowpass filters 11 and 12 to remove any ground clutter, to phase shifters 13 and 14, which introduce a differential phase shift of 90 degrees to the outputs. The resultant Doppler signals are in phase or in antiphase, depending on said motion sense, and are tested for 'their relative phase, by being multiplied together at 15, to give a positive output for one sense of motion and a negative output for the other sense. To reduce any remaining clutter the multiplier output is passed through an integrating low-pass filter 16 such that from pulse to pulse, the signal from a moving target increases as the square of time, whereas clutter only increases linearly with time.

Title: Fuel injection systems
IPC: F02M69/26
Filed: 1970-07-09
Abstract: 1319540 Regulating fuel injection engines ROBERT BOSCH GmbH 9 July 1970 [9 July 1969] 33265/70 Heading F1B A fuel injection system comprises in an air intake pipe 1, a manually operable throttle 3 and a throttling element 2, responsive to pressure upstream and downstream of it, controlling a fuel metering valve 14 to operate with a constant pressure gradient, and a fuel injection nozzle in which the fuel is treated with air from the intake pipe. A control spool of the metering valve has an oblique control edge 14' which is rotated to control a flow cross-section, the spool being also axially displaceable to shut off fuel flow. The fuel injection nozzle has a liquid nozzle 40, a space 51 for introducing air, an intermediate nozzle 52 and a normally open liquid nozzle closing element 38 hydraulically controlled by the control spool. A pump 16 supplies fuel via line 19, flow area 22, chamber 25 and line 29 to the fuel nozzle 34 where it enters a chamber 50 tangentially. The pressure across flow area 22 is controlled by a spool 26 moved by a diaphragm 27 subjected to the fuel pressure upstream and downstream of area 22. When fuel-flow should cease e.g. during engine overrun, an electromagnet 37 is energized to move spool 14 to the right thereby admitting fuel pressure via groove 42 and line 41 to act on member 38 which closes nozzle 40. When fuel flow is restarted member 38 is spring returned and the fuel pressure in line 41 is relieved through line 43. A valve 44 maintains the fuel in line 41 at low-pressure. In modifications element 2 may be replaced by a piston, pivoting valve or a baffle plate and piston 5 may be replaced by a diaphragm.
