Title: Improvements relating to electric switches
Inventor: ARNOLD CHARLES LEONARD
IPC: H01H19/62
Filed: 1962-11-07
Abstract: 1,060,152. Cam-operated switches. M.K. ELECTRIC Ltd. Nov. 7, 1963 [Nov. 7, 1962], No. 42102/62. Heading H2B. A ceiling switch has contact-operating cams mounted coaxially with the ratchet device which operates them. The base 2 is formed with projections 12, 13 which support a spindle 20. This has two cams 55, 56, rigidly fixed to it, which are rotated by an element 66, loosely mounted on the spindle but carrying spring- loaded plungers 63, 64 which act as pawls for co-operation with ratchet teeth formed on the adjacent faces of the cam members. An operating cord is attached to the element 66 and the latter is spring-loaded so that repeated pulls on the cord rock the element 66 and advance the cams 55, 56. These cams have indentations of alternating depth for co-operation with cam followers on contact-bridging members 10, 11 which are consequently alternately set in closed and open positions. Each member 10, 11 is spring-loaded so that at one end (44) it rocks on one fixed contact (40) while its other end (36) is urged towards a second fixed contact (35).

Title: Exposure control systems
IPC: G03B7/097
Filed: 1975-10-15
Abstract: 1523473 Shutter-diaphragm control WEST ELECTRIC CO Ltd 15 Oct 1975 [18 Oct 1974] 42112/75 Heading G2A A shutter-diaphragm is driven by a pulsed step motor 1 to provide an aperture and exposure time dependent on subject brightness, the motor being locked against movement when the shutterdiaphragm is closed in order to prevent accidental operation e.g. due to mechanical shock. As shown upon shutter release: (a) a switch 66 is closed to turn on a thyristor 69 which turns on a power supply transistor 67. This energizes an electromagnet 25 which pivots a brake arm 22, Fig. 2, from the dotted line to the solid line position to free motor 1 for rotation. (b) transistor 67 also turns on a transistor 63 after a time delay introduced by a capacitor 62 to ensure that brake arm 23 has completed its movement. Transistor 63 switches transistors 64, 65 which provide inputs to NAND gates 38, 39, so that these gates turn on an AND gate 37 to energize a driving circuit 26 which switches on the motor to open the shutter-diaphragm blades. The NAND gates 38, 39 also initiate charging of integrating capacitors 42, 50 through respective photo-cells 41, 16. (c) movement of the blades causes a grating 17 carried by the blades to admit light to a photo-cell 19 which turns on a transistor 44 to trigger a monostable multi-vibrator 27 to its unstable state. This turns off AND gate 37 to halt the motor. The aperture has by now opened to f/16. (d) when the multi-vibrator 27 returns to its stable state the motor 1 restarts, opens the blades to f/8 and is switched off again by reason of grating 17 and photo-cell 19. (e) pulsed opening of the blades continues until capacitor 42 is charged. This turns off AND gate 37 to stop further energization of drive circuit 26 and sends an instruction to input W of circuit 26 to ready it for reverse operation. (f) when capacitor 50 is charged and after a time delay introduced by a capacitor 32, an AND gate 56 is turned on to re-energize circuit 26 to close the blades. (g) the motor closes the blades as before in steps under the control of grating 17, photo-cell 19 and multi-vibrator 27. (h) when the blades are closed, a switch 59 is closed to turn on a transistor 71 which discharges a capacitor 70 to turn off thyristor 69. This turns off transistor 67 to de-energize the electromagnet 25, so that a spring 23 can return the arm 22 to its locking position. An alternative lock construction is shown in Figs. 5A, B, C (not shown).

Abstract: 897,885. Photographic cameras. GAUTHIER G.m.b.H., ALFRED. Dec. 15, 1959 [March 2, 1959], No. 42622/59. Class 98(1). [Also in Group XL(b)] In a photographic camera having a lens shutter-diaphragm mechanism which may be adjusted to different apertures and exposure times defining a range of uniform exposure value gradation by setting members for diaphragm aperture and exposure time which are fixedly connected together, the diaphragm blades are arranged to be actuable by two displaceable and relatively adjustable members, each of which is actuable only when the other member is secured by locking means in a fixed end position, one such member being controlled by a setting member which is connected to the exposure time setting member and is displaceable by driving means at shutter release from one end position to a position determined by a light meter whilst the other member is manually actuable and is connected with a shutter control mechanism for influencing the amount of open time of the shutter. As shown (diagrammatically) diaphragm blades 4 are provided with two actuating rings or members 3, 5, ring 3 of which is coupled by way of pivoted bell crank lever 6 and cam slot 10a to a setting member 10 which is fixedly connected by strips 11, 12 to a first exposure time setting member I. The member 10 is engaged by a driving spring 14, the arrangement being such that, on shutter release, the members 10 and 1 are released and run down under loading of spring 14 until checked by cam 1b coming into abutment in known manner with an abutment 13a positioned according to the reading of a light meter (not shown). The member 10 is returned to its original position (shown) by a member 15 coupled by way of a gear 16 to a film advance or shutter cocking mechanism (not shown). The member 15 is held in the tensioned position (shown) by a spring urged latch 17 coupled by means not shown to a body release member. The other diaphragm actuating ring 5 is coupled by way of a pivoted bell crank lever 20 and a cam slot 19a to a manual diaphragm setting member 19 which is connected to a further exposure time setting member 25 which has three setting ranges, one for setting in terms of light values in which predetermined combinations of exposure time and diaphragm aperture are set, one for use with flash photographs in which the shutter speed is maintained at a constant low value and one for "B" photographs in which by way of a member 24 engaging with a cam portion 25a the shutter is set for "B" exposures. In order that only one of the setting members 10 or 19 may be effective at a time, a pivoted spring urged latch 29 is provided co-operating on the one hand with a recess 10b in the slide 10 and on the other hand with cam portion 19c and d of the member 19. The same pin 2 of a conventional shutter retard mechanism co-operates alternately with both cam 1a and cam 25c. Specification 802,020 is referred to.

Abstract: 909,184. Liquid-ring pumps. ATKINSON CO., GUY F. Dec. 15, 1959, No. 42660/59. Class 110 (1). A liquid-ring pump comprises an elongated casing having end walls and at least one intermediate wall defining a number of rotor chambers, aligned rotor shaft openings in the walls, inlet and outlet ports radial to the shaft opening in each wall, longitudinal inlet and outlet passages within the casing extending along opposite sides thereof, inlet passages in each wall interconnecting the longitudinal inlet passage with the inlet ports, and outlet passages in each wall interconnecting the longitudinal outlet passage with the outlet ports. In the two-rotor liquid-ring pump shown in Fig. 2, the casing is split on a horizontal plane, the lower half being shown in plan view in Fig. 6 and the upper half being shown in inverted plan view in Fig. 7. Fluid is drawn in through an inlet 25, Figs. 3 and 6, into a longitudinal passage 158, from which it passes by way of passages 160, 161 within the central wall of the casing and through diametrically opposite ports 145, 154 into a central port member 76. The fluid flows out the two ends of the member 76 through ports 146, Figs. 2 and 4, into the upper lobes 40 of a pair of two-lobe working chambers 29, and also through ports 155 (not shown) into the lower lobes 40. After compression, the fluid returns to the central port member 76 by way of ports 149 and 152 and passes through diametrically opposite ports 148, 151 into passages 176, 177 within the central wall of the casing and thence through a longitudinal passage 175 into an outlet 26. Similar passages and ports in the two end walls of the casing and two end port members 75 provide further connections between the upper and lower lobes 40 and the longitudinal inlet and outlet passages 158, 175. Water under pressure is supplied by way of a valve 95 and intake 94 to a longitudinal passage 93 connected by ducts 99, 100 to the annular space 98 between each end port member 75 and the rotor shaft. From each space 98 the water passes to notches 107 and also, by way of ducts 106 to grooves 105. As each rotor vane 36 passes over the grooves 105 and notches 107, water is forced into a groove 39 in the inner end of the vane to form a seal between the vane and the surface of the corresponding end port member 75. Similar passages for the supply of sealing water are provided in the central wall of the casing and the central port member 76. The central port member 76 supports a split shaft bearing 62. Access to the bearing 62 can be gained by removing the top half of the pump casing and an upper, central, semi-cylindrical portion of the central port member 76, The bearing 62 is preferably lubricated by water supplied from a pipe 140 by way of a passage 139. Three or more rotors may be provided.

Filed: 1961-12-05
Abstract: 964,267. Measuring resistance of soil to piles. FOUNDATION ENGINEERING Ltd. Dec. 3, 1962 [Dec. 5, 1961], No. 43470/61. Heading G1S. A method of determining the resistance of soil to a pile comprises making a bore in the soil to receive the pile, inserting therein a disc having a shallow recess on its underside which houses pressure developing means, e.g. expansible diaphragm chambers. A similar pressure developing means of larger cross-section, in fact with a cross-section the same as the pile is placed on the disc and the pile is driven into the bore until it contacts the upper pressure developing means. Then the pressure is increased in the lower pressure developing means and from the downward movement and the pressure the resistance of the soil to the base of the pile can be determined. During this measurement the pile remains stationary since due to its larger cross-section the force required to move the pile is greater than that to move the soil. The pressure in the upper pressure developing means is then increased and from the upward movement of the pile and the pressure the skin resistance of the soil can be calculated. However if the resistance at the base of the. pile is less than the skin resistance the pile does not move upwardly and the skin resistance is measured by placing the larger pressure developing device between two parts of the pile.

Abstract: 1,184,119. Travelling-band suction filters. BOWSER, Inc. 26 Sept., 1967 [12 Dec., 1966], No. 43740/67. Heading BID. In a filter of the kind having a band 20 travelling over apertures 50 in a suction box 28 immersed in a tank 10 containing liquid to be filtered, the band 20 has its edges (52a, Fig. 4) magnetically attracted to the surface of the suction box 28 in order to reduce leakage of liquid therebetween. As described, suction is applied by pump 30; when the vacuum inside box 28 is high (owing to clogging of filter band 20), switch 80 senses this and operates valve 82 to short out the vacuum line; this causes pressure to use, and at a predetermined level sensed by switch 81, circuit 83 is energised to drive band 20 a predetermined distance, whereupon high vacuum is restored to re-commence filtering. The band 20 may be cleaned by steam (73), air, vacuum (75) and a rotary wire brush (72), Figs. 8, 9 (not shown). Alternatively, it may comprise an expendable medium 39 carried by an endless belt 52, filtrate being applied at 40 (Fig. 1) to seal the band, 39, 52 against the surface 45 of suction box 28. The edges are sealed by the attraction of magnetic elements 52a, 63, Fig. 4. The rollers 24, 25 on which the band moves may be grooved at (66), (Fig. 6, not shown) in order to ensure vacuum application at the band edges. The suction apertures 50 are provided by slots transverse to the corrugations of an expanded metal sheet (Fig. 5, not shown).

Filed: 1969-09-04
Abstract: 1,254,915. Pneumatic conveyers. INTERNATIONAL BUSINESS MACHINES CORP. 4 Sept., 1969 [13 Sept., 1968], No. 43759/69. Heading B8A. [Also in Division G1] In a fluidic apparatus for testing and sorting miniature components such as magnetic cores, ports 38, 40 are spaced along the main flow channel 32 and are connected by hoses 46, 48 to electro-fluidic transducers for alternately applying vacuum and pressure into the channel 32 to advance the cores from a hold station to a test station. At the test station, a reciprocating probe, Figs. 3, 5 (not shown), effects tests on each core and causes signals to pass to a logic circuit, Fig. 8 (not shown), connected to further electro-fluidic transducers associated with accept and reject ports 42, 44 in the channel 32. As a result of the tests, pressure is applied to the port 40 and to either the port 42 or the port 44 thereby causing the core to pass along the channel 32 into either a channel 34 leading to a container for accepted cores or a channel 36 leading to a container for rejected cores. Prior to the actuation of the probe at the test station, an optical position sensor, Fig. 4 (not shown), determines whether the core is properly seated at the test station adjacent the port 40. If the sensor detects an incorrectly positioned core, it signals a further transducer which causes a pulse of air from a clearing port to discharge the defective core upstream through the inlet 29. If the core is correctly positioned, the probe is actuated to test the core. The cores are fed into the apparatus by a vibratory feeder.
