IPC: G01B13/00
Filed: 1955-09-14
Abstract: 762,164. Pneumatic linear-dimension gauges. SIGMA INSTRUMENT CO., Ltd. Sept. 14, 1955 [Dec. 30, 1954], No. 37674/54. Class 106 (2) A pneumatic gauge .comprises a gauging jet 19, Fig. 1, for co-operating with a workpiece 20 to be guaged, a pressure indicating device 12, an air supply pipe 3 leading through a constriction 14 to the jet, a conduit 15, 17 between the device 12 and the pipe 3, a valve 16 in this conduit and means controlling the valve 16 so that when a workpiece is in gauging position the valve is open and when there is no workpiece in gauging position the valve is closed, whereby when the workpiece is removed from gauging position the valve is closed before leakage of air from the jet 19 changes thus enabling the device 12 to maintain its indication after the workpiece is removed. Preferably the device 12 consists of a manometer tube connected by a conduit 6 through an orifice 5 with the air supply, an adjustable valve 7 controlling leakage to atmosphere being provided. As shown, the valve is controlled pneumatically by means of a monitor. ing jet 25 associated with the workpiece 20, supplied with air through an orifice 22 and conduit 4 and connected by a further conduit with the valve 16 the arrangement being such that the reduced leakage of air from the jet 25 in the presence of a workpiece causes the valve 16 to open. Alternatively electromagnetic means may be provided for controlling the valve 16. As shown in Fig. 2, the valve 16 comprises a Schrader tyre valve housed in a cylindrical casing 26 connected at 15 to the gauging jet 19 and at 17 to the manometer 12. The end 32A of the valve pin 32 abuts against a push rod 38 slidably mounted in a mounting 24 and whose other end is in contact with a flexible membrane 39 whose opposite face co-operates with a further push rod 42 whose other end contacts a diaphragm 43 subjected to the pressure in the conduit 4. When a workpiece 20 is correctly positioned the leakage from the monitoring jet 25 decreases and the pressure in the conduit 4 increases to deflect the diaphragm 43 to move the rods 38, 42 in the direction to open the valve 16, the pressure at the gauging jet being then fed by inlet 16 to the manometer via outlet 17. Specification 724,205 is referred to.

Filed: 1929-12-14
Abstract: 345,261. Photographic cameras. SAUNDERS, H. C., 8, Grafton Street, New Bond Street, London. Dec. 14, 1929, No. 38351. [Class 98 (i).] A camera with means for simultaneously focusing two lenses and causing their axes to converge on the object has two shutters which are released and set from a single part, two plate or film carriers and means at the side of the camera for viewing the object through one lens prior to exposure. In one form, Fig. 2, the lenses are carried by the front board 8 which is moved for focusing by the rack 5 and pinion 6. A member 13, supporting one of the lenses 17 and adapted to slide on a wedge shaped block 12 on the board 8, carries a roller 15 engaging a fixed cam 16. As the board 8 is moved backwards or forwards the lens 17 is moved awav from or towards the lens 11 under the action of the spring 18 or cam 16. When focusing a tube 24 is pushed into the camera body so that a mirror 26 intercepts the image formed by the lens 11 and throws it on a ground glass screen 25. The image formed by the lens 17 is recorded on plates or cut films in the dark slide 20. The lens 11 projects an image on to the film roll 21, the latter being then developed, reversed, and shown to the sitter. A spring-urged polygonal film holder adapted to be retained in the exposure position by the engagement of a release lever with notched disc on the holder may be used in a modification.

Title: Actuating mechanism for operating handle of electrical switching device
IPC: H01H3/26
Filed: 1972-08-18
Abstract: 1368365 Actuation of switches; automatic circuit-breakers SQUARE D CO 18 Aug 1972 [21 Sept 1971] 38550/72 Heading H1N An actuating mechanism for moving an operating handle of an electric switch, e.g. an automatic circuit-breaker, to "on" and "off" positions, comprises a reversible motor having an output shaft 21, a crank arm 22 resiliently connected adjacent one end to the shaft, a handle actuating member 30 secured to the other end of the crank arm, normally closed " on " and "off" limit switches 44, 46, and a lost motion connecting device between a limit switch actuator 42 and the crank arm. As shown the resilient connection is provided by a blade spring 24 which extends through a slot in the base 22c of the U-shaped crank arm and through the shaft 21 and is secured between pins 25. A link 33 has pins 34, 35 extending on either side of the spring 24 into a rectangular aperture 22d in the crank arm 22. An actuating lever 37 is pivoted at 40 and to the link 33 at 38, the lever 37 extending through a U-shaped part of the limit switch actuator 42. The free movement of the lever 37 in the U-shaped part of actuator 42 is sufficient to allow a geared motor (not shown) to fully close or open a circuit-breaker (not shown) before the appropriate limit switch is opened to stop the motor. This free movement or lost motion is also sufficient to permit a tripfree action to occur and to enable the circuitbreaker handle to move into an intermediate tripped position. In alternative arrangements, an extended portion of the spring blade may operate a limit switch actuator, Fig. 6 (not shown), or the switches may be operated by cam surfaces on a member connected to the crank arm, Fig. 7 (not shown).
Patent GB-385536-A (GB)
Abstract: 385,536. Television. ETABLISSEMENTS E. BELIN, 56, Faubourg St. HonorÚ, Paris. June 23, 1932, No. 17803. Convention date, June 30, 1931. [Class 40 (iii).] In an arrangement for transmitting picture telegraph and like signals of varying intensity by converting them into signals of constant intensity but of varying duration, light from a constant source in its passage to a photocell C traverses a diaphragm or screen 3 having a transparent section g, h, i, the width of which varies at different parts of its height. The beam from the source is deflected towards the appropriate part of the section g, h, i by an oscillating mirror M, the angular position of which is adjusted in accordance with the variations of current derived from the changes in shade of the photograph &c., which is mounted on a cylinder and scanned in the usual way along a helical path. Coacting with the diaphragm 3 is a rotating disc D having a number of equally spaced radial slots mn, pq, arranged so that only one slot at a time can be in effective co-operation with the section g, h, i. In this way, as the position A, B of the luminous spot produced by the mirror M on the screen 3 alters, so does the length of time vary that the slot m, n and section g, h, i permit the passage of light. Thus, at the receiving station electrical impulses of constant intensity but varying length are received, and are converted into light by use of an oscillograph, Kerr cell and gas lamp or similar known means. By varying the shape of the section g, h, i a positive or negative image may be obtained as required. A lens (not shown) is arranged adjacent to the screen 3 for condensing the light beam upon the cell C.

Abstract: 842,765. Moulding rims on respiratory masks. SMITH, J. J. Dec. 11, 1957, No. 38565/57. Class 87(2). [Also in Group VI] A face mask is made from a laminated sheet of air permeable fabric, the edges of which have a synthetic resin rim moulded on to them, for the attachment of head bands. The fabric used is preferably made from six layers of gauze, with layers of cellulose fibres between them and these fibres may be impregnated with carbon or other adsorbent. The plastic rim 35 is moulded on around the outer edge of the fabric blank and also around the eye holes. The lower edge is then folded and secured by heating so as to form a curved portion under the chin, the head straps 16 are attached to the projecting edges 21 of the rim 35 and the eyepieces are fitted. In attaching the rim, pressure is applied over a continuous band spaced slightly inward from the edge of the fabric, so that the various layers splay out at the actual edge. This is treated with a stiffening adhesive and the blank is then placed in a mould, to which the synthetic resin for forming the rim is subsequently introduced.

A piece of salt 61 having a longitudinal bore 62 is mounted in a flame ionization detector for a gas chromatograph so as to be movable in the direction of a flame nozzle 16. The latter comprises a metal portion 18 and insulating portion 17 and is secured by a nut 21 in a ring 14 on a base 11 having an opening 12 for compressed air and an opening 13 for a mixture of carrier and combustible gases. Nozzle connecting springs 28 pass through an insulating bush 27 screwed into a hole 26 in the wall of a housing 23 having a cylindrical bore 24 which at one end fits over the ring 14 and at the other end is closed by a cover 63. A means for igniting the combustible gas is provided (not shown). The piece of salt 61 is held in a collector ring 59 secured to a conductor 55 passing through a tube 53 to a coaxial plug 54 which can be rotated through at least 180 degrees. The tube 53 is secured by a locking screw 47 in a block 42 which slides on a guideway 31 between ribs 32 under control of a nut 49 having a flange 51 which engages a slot 37 in a plate 34 fixed to the housing 23 by a clamping screw 64. Two pieces of salt may be mounted in opposite ends of the ring 59 and brought into use successively by rotating the ring through 180 degrees. Alternatively, four pieces of salt supported in a crossshaped holder (Fig. 5, not shown) may be utilized successively by rotating the holder through 360 degrees. The detector may be used to indicate substances containing P, N, Br and/or I in a mixture of such substances with hydrocarbons and Cl containing substances by feeding the mixture, if necessary in a carrier fluid, to the detector which is set for optimum ionization in the presence of combustible gas and O and then increasing the flow of combustible gas until a setting is reached where the ionic currents due to the hydrocarbons and Cl-containing substances are distinguished in relation to the ionic currents due to the remaining substances (Fig. 6, not shown). The flow may be further increased to a point at which an inversion of ionic current occurs and non-phosphorated compounds are distinguished by a negative amplitude on the chromatogram (Fig. 7, not shown). The detector may also be used as a flow meter by calibrating the ionic current of a given substance for different rates of flow of carrier gas (Fig. 8, not shown).

Abstract: 1498736 Making electrode screw joints LECTROMELT CORP and AVRR 22 Sept 1975 [23 Sept 1974] 38799/75 Heading B3N [Also in Division H5] A device for screwing a new electrode section 41 on to an electrode section (21, Fig. 1, not shown) in an arc furnace (10) comprises a continuous flexible band 66, openable and closable at a pin (67) to encircle the electrode section 41, driven by an air, hydraulic or electric motor (74) via a speed reducer (72) and sprocket 71, guided by idler wheels 69, 70, 83, and tensioned by means acting on one, 83, of the idler wheels. The device includes a base plate 65 on an arm 57 longitudinally movable by rack and pinion 60, 61 and rotationally movable via a pedestal (53) in a socket (52). Rollers 85, 86 rest on the electrode section to resist lateral movement due to the pull of the device. From one socket the device may couple sections to all three electrodes 20-22 of the furnace. The device may be lifted as a whole for use in corresponding sockets adjacent other furnaces in the plant. To add the new electrode section, arm assembly (25) holding the old electrode section (21) is lowered until the section rests on the melt or flow of the furnace. Clamping shoe (34) is slackened to permit the arm assembly to be raised to near the top of the old section (21) when it is re-tightened to prevent rotation of the section. The new section 41 is brought with its connector (e.g. metal or carbon ripple or an extension of the electrode section into alignment with the old section. The band is unpinned, passed around the new section, repinned and the position of the coupling device adjusted so that the new section rests against rollers 85, 86 in alignment with the old section. Motor 74 drives the band to screw in the new section until the motor stalls or the band slips. The furnace is emptied via spout (13) by rocking on rockers (19) that run in a toothed rack.
