Title: Improvements in or relating to ignition systems for internal combustion engines
IPC: H02K21/38
Filed: 1966-02-10
Abstract: 1,069,822. Ignition systems. ROBERT BOSCH. Feb. 10, 1966 [Feb. 13, 1965], No. 5799/66. Heading F1B. [Also in Division H2] The invention relates to an ignition system which comprises switch means for controlling the primary current of an ignition coil in response to the output of a generator coupled to the engine. According to the invention the generator comprises an armature 10 having at least one pair 11, 12 of magnetic conductors mounted in diametrically opposed peripheral regions thereof and at least two pick up coils 15, 18 wound on iron cores and located in two separate non -diametrically opposed positions around the armature, the magnetic flux linking one of the two pick up coils, and therefore the magnitude of the signal induced therein being dependent on the engine speed and the inlet manifold vacuum and the system further comprises signal summation means 16 for adding the signals induced in the two pick up coils to produce a control signal for controlling the switch means. As shown the core 14 carries an energizing coil 20 which is connected to at least one source of direct current. When the engine speed is low the output of the generator 21 is also low with the result that only a small magnetizing current will flow through the energizing coil 20. The slider of the variable resistor 22 is coupled to the mechanism which controls the opening and closing of the butterfly valve in the engine carburetter (not shown). The switch means associated with the primary circuit of the ignition coil may comprise a multivibrator 25. The engine flywheel may comprise the armature.

Title: Improvements in and relating to diaphragms for use in the recording, or reproduction of sound, or other vibratory motion
IPC: H04R9/04
Filed: 1929-02-22
Abstract: 329,328. Irvine, M. M. Feb. 22, 1929. Diaphragms; transmitters in which a soundcontrolled light-beam acts on a photo-electric element.-A. diaphragm for use in the recording or reproduction of sound or other vibratory motion is provided with one or more circuitous electrically conducting paths formed of electrolytically deposited material. According to one method of forming such a diaphragm, the outline of a spiral coil is drawn and then photographed. The positive print of this photograph is taken on a sheet of electric insulating material, such as glass, mica, celluloid or insulated metal, coated with a sensitizing material such as silver emulsion and copper or other electric conducting material is then electrolytically deposited on the silvered outline of the coil. A second spiral coil may also be deposited on the reverse side of the diaphragm, the two coils being joined at the centre automatically by piercing the diaphragm centrally before depositing the conducting material thereon. The external leads, are soldered or otherwise attached to the outermost coils of the spirals and may be used for supporting or positioning the diaphragm. The diaphragm may be used in microphones or loud-speakers and when the base or diaphragm proper is formed of transparent material it is particularly suitable as a diaphragm or graticule for photo-electric recording or reproduction of sound e.g. as described in Specification 329,320, [Class 40 (ii), Phonographs &c.]. The diaphragm may also be made by a photo-etching process in which case it is completely electroplated, the plating is then coated with a photographic emulsion, then printed to form a spiral line thereon and finally treated in the usual way for photo etching.

Abstract: 139,766. Etablissements Rouchaud et Lamassiaude Soc. Anon, (Assignees of Soc. Rouchaud et Lamassiaude). March 5, 1919, [Convention date]. Presses; feeding; delivery; strain, preventing.- Bricks are positioned by a reciprocating table a in front of the mould and are transferred thereto by a plunger l, which is then held by a sliding locking-plate q whilst pressure is applied through the piston r by a plunger operated by an eccentric on the main shaft b. After pressing, the plate q and plunger l are withdrawn, and the finished brick is delivered on to the table a by the piston r. The shaft b effects the movement of the plunger l and the discharge movement of the piston r through a cam p, lever o, rod n, and toothed quadrants m, x, and operates the plate q through a cam v, levers u, s, and rod t. Motion is imparted to the table a through a pinion on a shaft driven alternately in opposite directions by a pair of pinions disposed on opposite sides of the shaft b and driven by a toothed quadrant mounted thereon. The unpressed bricks are placed on the table a before or during its return movement, and are positioned thereon by a fixed stop. The pressed bricks may be detached from the piston r by a pivoted auxiliary table. Excessive pressure is taken up by springs y. The press may be provided with an automatic device for stopping the machine should the product exceed predetermined dimensions; and may be combined with a conveyer for transferring the pressed bricks to a drying-kiln.

Title: Improvements relating to spring wound mechanisms
Inventor: HARRIS HARRY GILBERT
IPC: G10K1/074
Filed: 1955-02-28
Abstract: 795,817. Spring-actuated door-bells. GENT & CO., Ltd. Feb. 9, 1956 [Feb. 28, 1955], No. 5888/55. Class 10. [Also in Group XXXVIII] A spring-actuated door-bell of the type in which the spring is wound by rotation of the bell-cover has an indicating device to show when the spring has run down beyond a predetermined point. The bell shown comprises a base 1 supporting pins 7a, 7b, 7c and a rotatable spindle 4. The pins carry a triangular plate 8 held in position by a spring strip 10, the plate serving as a bearing for the spindle 4 and axles 19, 25 and a push-rod 30. The bell-cover 11 is screwed on to the spindle 4 and when rotated winds a spring 5 attached to the spindle and to the pin 7a. A gear-wheel 20 is secured on the spindle and this drives, whenever the bell is operated, a pinion 21 integral with a toothedwheel 22 rotatably mounted on the axle 19. This rotation effects, whenever the striker arm 24, is free, oscillation of the arm about the axle 25 through the engagement with the wheel 22 of a striker arm part 23. The bell push-rod 30, which is spring-biased outwardly, carries a conical flange 32 which normally contacts the striker arm part 33 and prevents the bell ringing. Inward movement of the rod, however, removes the stop flange 32 and allows the arm 24 to oscillate. Pivoted at 7a is an indicating member 52 biased by a spring 53 in a clockwise direction. Such movement is prevented when the spring is sufficiently wound by a bell-crank lever 40 pivoted about the pin 7b and clockwise biased by a spring strip 43. The arm 42 of the lever 40 is spring-urged against the spring 5 whilst the arm 41 has a notch 50 which holds, through an abutment 51, the member 52 against clockwise rotation as long as the spring 5 is sufficiently wound. On expansion of the springs to a predetermined point the lever 40 moves the notch 50 from the abutment 51 and the member 52 springs into a " spring rundown " indicating position which needs to be positively re-set by winding the spring and pressing the member 52 inwardly. Fig. 5 shows the bell used in combination with the fire detector 74 of Specification 768,353, [Group XXXVIII]. Here the push-rod 30 is moved inwardly by a bevelled edge of a slot 63 in which the rod is located, and which is formed in a strip 62 slidably attached to a mounting-plate 60. The strip 62 is formed with feet 70, 71 which are engaged by the part of the detector which drops on actuation of its bimetallic strip due to temperature rise.
