Title: Ignition systems for internal combustion engines
IPC: F02P5/10
Filed: 1973-06-06
Abstract: 1428209 Timing ignition ROBERT BOSCH GmbH 6 June 1973 [7 June 1972] 26973/73 Heading F1B Two-stage retardation of the ignition timing of an I.C. engine is effected by a vacuum servo 40 acting through a diaphragm 29 and a rod 15 on a breaker plate 11 to move the rod initially a distance a against a first spring 19 until a nut 41 on the rod abuts a spring-loaded stop body 17 which, for the second stage movement, is itself moved a distance b until the end 48 of the rod abuts a stop screw 52. The first stage corresponds to idling operation of the engine, or low speed engine braking, and the second stage to high speed engine braking and rapid heating-up of exhaust gas aftertreatment devices. As shown, an annular vacuum chamber 43 moves the stop body 17 during second stage retardation. The vacuum servos 40, 43 are connected to the inlet manifold by valves responsive to the carburetter butterfly valve position and engine speed or exhaust gas aftertreatment device temperature respectively, a vacuum being applied to the chamber 40 whenever it is applied to the chamber 43. Again, Fig. 2 (not shown), an ignition advance chamber (53), connected to the inlet manifold under part-load engine operating conditions, is provided on the opposite side of diaphragm 29. Also, Fig. 3, (not shown), the first retard chamber 40 is formed as the annular chamber, and the retard chamber 43 is partially defined by the diaphragm 29. Again, Fig. 4, (not shown), the second retard chamber is replaced by an electromagnet (86), and Fig. 5 (not shown), an advance vacuum chamber (53) is provided.

Abstract: 330,194. Svenska Aktiebolaget Gasaccumulator. Oct. 11, 1928, [Convention date]. Cooking-stoves; joints and connections; heat retainers. -In a solid-fuel stove with a metallic heat-accmnulator and a hot-plate 2 supported by a tubular member or " fire-tube " 1, the latter is adapted to expand independently of the other parts of the stove in order that the plate 2 may not move appreciably in relation to the top plate of the stove. In the construction shown, the tube 1 is supported by screws 8 which pass through members 7 projecting from the tube and rest upon brackets 9 secured to the stove casing, allowing the plate 2 to be adjusted in height. The lower end of the tube 1 rests in a sand seal 3 which allows the tube to expand downwardly. In a modification, the brackets 9 are approximately at the level of the lower end of the tube 1, and the members 7 are extended to form laterally and downwardlyextending arms sufficiently remote from the tube to be substantially unaffected by the heat. In a further modification, the screws 8 pass through the upper ends of members secured to the lower end of the tube and extending up in proximity to it so that they undergo substantially equal expansion. In another construction, the screws 8 rest on the upper ends of supports, the lower ends of which are pivoted near the bottom of the stove, thus allowing lateral movement of the tube. The lower end of the tube 1 is slidably connected to the top of the ashpit by a packed joint.

Title: Improvements in or relating to radio direction finding apparatus
IPC: G01S19/46
Filed: 1932-09-30
Abstract: 408,211. Directive wireless signalling. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Martin, D. K.; 28, Undercliff Terrace, West Orange, New Jersey, U.S.A.) Sept. 30, 1932, No. 27207. Convention date, Nov. 27, 1931. [Class 40 (v).] For determining the direction of incoming signals, the phase of the current generated by rotating a coil in the earth's field is compared with the phase of a current produced under the control of the signals and which depends on their direction. In the embodiment described, the search coil 9 of a radio-goniometer is continuously rotated by means not shown and generates two currents, one of the frequency of the incoming signals modulated by a frequency double that of rotation and of phase depending on the direction of the incoming signals, and the other, due to the earth's field, of frequency equal to the frequency of rotation and of phase depending on the direction of the earth's field. The former of these is selected by the filter 14 and the latter by the filter 13. The filter 14 is followed by high frequency amplifier 15, detector 16, harmonic producer 17, and filter 18 (for producing a definite harmonic of the low frequency) and low frequency amplifier 23 feeding one winding of a synchroscope or phase meter 25. The filter 13 is followed by low frequency amplifier 19 phase adjuster 20, harmonic producer 21 and filter 22, producing a current of the same frequency as apparatus 17, 18 in the other path, and a low frequency amplifier 24 feeding the other winding of the instrument 25. The deflection of the latter is therefore dependent on the angle between the earth's field and the incoming signals. The invention is primarily applicable to navigating aircraft and for this purpose the phase adjuster 20 is adjusted at the commencement of the flight to give a zero deflection of the meter 25 when the aircraft is heading on to the correct course and deflections thereafter indicate deviations from the course. The phase adjuster 20 may also be used to compensate for any incidental phase displacements in the circuits.

Title: Improvements in or relating to shoe sewing machines
IPC: D05B15/04
Filed: 1946-09-11
Abstract: 616,616. Sewing-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. Sept. 11, 1946, No. 27261. Convention date, Sept. 12, 1945. [Class 112] The edge-gauge of an outsole sewing-machine is movable laterally during stitching to occupy the appropriate one of three positions for sewing the heel-seat, shank, and front portions of the shoe respectively, movement from one position to the next being produced by a pull or push on a handle, means being provided to prevent shift from one extreme position to the other in one movement. In the arrangement shown the edge gauge is formed on a lever 98 of which the tail is spring-pressed against a cam 96 having on its spindle a pinion meshing with a rack 90 adjustably fixed to a sliding member 104. A hand lever 84, pivoted at 88, carries slidably a bar 110 which has at one end a pin 106 engaging a slot 108 in the member 104 and which is shifted by a hand lever 86 pivoted on the lever 84 ; the pin 106 also engages an L-shaped slot 120 in a fixed member 116. Movement of the edge-gauge from the extreme retracted position shown is effected by pushing the handle 86 to move the pin 106 to the corner of the slot 120, the member 104 being shifted by reason of the inclination of the slot 108 ; movement from the intermediate to the forward position is effected by pushing the lever 84, either directly or by a further push on the lever 84, to carry the pin 106 forward along the second limb of the slot 120, taking the member 104 with it, this movement being limited by a stop-screw 122 carried by the lever 84. In a modification, Figs 8-17 (not shown), the rack 90 and member 104 are replaced by a toothed sector (58) and a pivoted member (64) respectively, and the latter member and the lever 84 are pivoted about the same axis and are frictionally connected so that the lever actuates the member but the latter can also be moved by the second hand-lever 86 which is linked to a slide guided relatively to the member. Specification 532,026 is referred to.

Title: Improved means for signalling or controlling the timing and sequence of operations
IPC: D06F39/00
Filed: 1932-10-04
Abstract: 403,783. Time switches. CLEGHORN, W. G., Rothney, Beaconsfield Road, Claygate, Surrey. Oct. 4, 1932, No. 27553. [Class 38 (v).] In apparatus for signalling the lapse of predetermined times or for controlling a sequence of operations, a clockwork driven disc or drum is provided with circumferential projections, spaced according to the time intervals required, which close electric circuits including signalling and/or controlling means, the drum being arrested at the end of one step and moved at the commencement of the next. As shewn in the figures the disc 18 is divided into segments corresponding in size to the operations to be performed and pins 19 and 20 are fixed at the beginning and end of each section respectively. The pins 19 are longer than pins 20 so that the pins co-operate respectively with spring sets 35, 36 carried by arms 26, 27. At the commencement of an operation or a time period the disc is stationary, sliding on a clockwork driven shaft, with a pin 19 closing contacts 35 and lighting the lamp 12. When the cable 44 is operated, the sleeve 40 is rotated, swinging arm 26, clockwise to release the drum and extinguish the lamp and allowing 27 to move forward to bring 36 into the path of 20. When the period of operation has expired, 20 engages 36 and the other lamp 13 lights. The cable 44 is then released allowing the sleeve 40 and the arms 26, 27 to return to their original positions, pin 19 engages spring set 35 to light lamp 12 and hold the disc preparatory to tuning the next step in the sequence. The disc can be reset to its starting position by the operation of lever 25, cam 39 pushing back both arms 26 and 27 and arm 23 engaging pin 22 and rotating 18 to the position shewn.

Title: Improvements in or relating to cams
IPC: F16H53/04
Filed: 1919-11-08
Abstract: 164,037. Hall, R. F. Nov. 8, 1919. Actuating-mechanism.-In a machine for manufacturing glass articles wherein a stationary cam actuates valves on a rotating head controlling an air supply for shaping the articles, the adjustment of the cam shape from a distance enables the time and amount of the valve actuation to be regulated without stopping or shifting the machine. The cam comprises a plate Z carrying a ring 6 in which a number of cam or tappet elements 9 are mounted on vertical spindles in toothed engagement with radially slidable racks 8 normally pressed outwards by springs 14 and retracted more or less to rotate the cam elements by Bowden wires 13 leading to a convenient control position. A second form of cam shown in Fig. 3 comprises a pivoted element 15 connected by an elbow lever 17 to the Bowden wire 13<a>, a spring 14<a> acting in opposition to the Bowden wire. As the head of the machine rotates, the stationary cam elements control the lifting of valves k connecting a central air supply through radial passages C to pipes h leading to the blowing heads, the actuation being effected through levers 3 carrying cam engaging bowls 5. The pivotal supports 2 of the levers 3 are mounted in blocks s adjustable in position by means of set screws z against springs x. The levers 3 are bifurcated to straddle the blocks 2 and also the slidable caps m enclosing the springs p which retain the valves in their seats. A constructional form of adjustment for the operating end of the Bowden wire is shown in Fig. 4. Instead of tappet elements as shown, the cam may comprise an operating surface formed of interconnected links controlled by eccentrically disposed pins &c. upon rotatable axes independently adjusted by the Bowden &c. transmission means, or a flexible band may be brought to any required shape by similarly controlled independently movable elements. As a further alternative, the radial slides may be formed with heads constituting the cam elements. The Provisional Specification describes also an arrangement in which the rack and pinion adjustment is replaced by crank arms on the cam or tappet spindles directly connected to the Bowden wires.
