Title: Photoelectric arrangements for indicating the position of graduations
IPC: G01D5/26
Filed: 1966-07-26
Abstract: 1,148,785. Measuring position photoelectrically. SOCIETE GENEVOISE D'INSTRUMENTS DE PHYSIQUE. July 26, 1966 [Sept.7, 1965], No.33499/66. Heading G1A. The position of a graduation is measured by a device comprising a light-source, a deflector oscillating the beam from the source across the graduation, a photo-electric cell receiving the reflected beam from the graduation through the deflector, the source and cell being optically equidistant from the deflector so that the reflected beam always falls on the same part of the cell, and means for simultaneously moving the source and cell transverse to the paths of light emitted or received thereby. Light from the slot 1 passes through a beam splitter 7, defective 3 and is reflected from an oscillating mirror 4 on to the graduations 2. The beam reflected from the graduations passes via mirror 4 and objective 3 to beam splitter 7 which directs it to the photoelectric cell 6. In modifications, Figs. 2-6 (not shown) the order of the beam splitter deflector and objective may be permuted at will, the beam splitter may be replaced by a semi-transparent mirror, with or without a plane mirror to make the beams 8, 10 parallel, and the deflector may be constituted by an oscillating parallel sided glass block. The means for moving the source and cell transverse to the light beam may comprise awedge co-operating with the source and cell housing so that as the wedge is moved by a screw in the direction of the light beam the cell and source are moved transverse to the beam. The screw may be connected to a micromoter indicator, or the apparatus may be used for positioning a machine tool relative to the graduation.

Title: Circuit arrangement in keyed control oscillators
IPC: H04L27/04
Filed: 1947-12-22
Abstract: 629,865. Keying carrier frequencies. STANDARD TELEPHONES & CABLES, Ltd. Dec. 22, 1947, No. 33800. Convention date, July 20, 1943. [Class 40 (v)] The voltage applied to the keyed electrode of an oscillator valve has a characteristic such as to compensate for the fall in anode voltage as the oscillator is switched on and so maintain the oscillator frequency constant. The screen of the tetrode V, which is connected as an electroncoupled oscillator, is alternately connected to a negative voltage source - C; and to a potential divider R4, R5 across the H.T. supply +B. The output of this potential divider is stabilized by a glow discharge tube G and resistor R6, and is connected to the key by network R7, R8, C4, so that the screen voltage falls relatively slowly from the no-load value, the time constant being adjusted so as to compensate for any change in oscillation frequency due to the voltage drop in the anode supply.

Title: Improvements in or relating to carburetters for internal combustion engines
IPC: F02M69/00
Filed: 1937-12-09
Abstract: 507,212. Spray carburetters; vaporisers. BRUGGER, A., and EBNER, F. Dec. 9, 1937, No. 34102. Convention date, Dec. 9, 1936. [Class 7 (iii)] In a floatless carburetter using two different kinds of fuel, the change-over from one to the other is effected automatically by a compresser E driven by the engine. The compresser delivers air under pressure through a pipe 39 to a chamber 40, the pressure being transmitted through a pipe 46 containing a reservoir 47 to a spring-pressed piston 36. The latter is mounted on a rod 35 carrying piston valves 31, 32 which admit either light fuel from a pipe 34 or-heavy fuel from a pipe 33 through a passage 28 to a nozzle 21 controlled by a needle valve 22. As the air inlet valve 14 is opened a lever 26 simultaneously opens the needle valve 22 and a piston 42 which permits compressed air from the chamber 40 to be delivered through passages 19 around the fuel nozzle. Means may be provided to enable the change-over to be effected manually when the engine speed is low. The fuel and compressed airimpinge against the walls of a spherical chamber 3, surrounded by an exhaust jacket 7, and are delivered through a passage 9 into the intake manifold, where they mix with air passing through a chamber 8 around the exhaust jacket. Residues are removed from the chamber 3 through a passage 15. A separate carburetter B is used for starting.

Filed: 1974-08-02
Abstract: 1481721 Rotary positive displacement fluid machines J-P MARCEL 2 Aug 1974 [9 Aug 1973] 34111/74 Heading F1F In a rotary positive displacement machine of the type comprising two relatively rotatable parts defining an annular working chamber in which there is located an abutment carried by one of the parts and which is subdivided by a plurality of vanes carried by the other part, the vanes are reciprocated to permit passage of the abutment by fluid-pressure acting on the ends of the vanes. The vane ends are respectively located in one of two fluid filled annular spaces and in each of these spaces the volume defined between any two successive vane ends periodically varies during relative rotation due to vane controlling means extending into the annular space and this periodic variation is at least equal to the periodic variation of that volume of the annular space which is occupied by a vane end. As described axially sliding vanes 5 subdivide an annular chamber 7 in which is located an abutment 6 of the stator. The vane ends are located in a respective one of two annular, fluid filled spaces and define spaces 12 between any two successive vanes in each of these annular spaces. Due to vane controlling surfaces 17, 18 carried by the stator and extruding alternately into the two annular spaces the volume of the spaces 12 varies from a maximum 12À1 when two vanes are at positions 5À1, 5À2 to a minimum 12À2 at positions 5À3, 5À4. This volume variation is at least equal to the maximum value of spaces 14, which value equals the periodic variation of that volume of the annular space which is occupied by a vane end.

Dec. 11, 1935, No. 34311. [Classes 83 (ii) and 83 (iv)] [See also Groups II and XXXVI] Soldering.-A copper-plated ferrous metal strip is formed into a tube and is then heated by electrical resistance heating to a temperature below the melting point of the coating and is then immediately heated by the application of external heat to melt the copper to form an even coating on the exterior or interior or both sides of the tube and to weld together the overlapping portions. In the form shown copper-plated strip 1 is passed through tubeforming rolls 3 into a muffle 20 in which it is heated to a temperature approximating to but below the melting point of copper by alternating current passed through the tube between electrodes 10, 11 and 12, 13, the electrodes preferably being formed as rollers. After passing the electrodes 12, 13, which are located in a housing 21, the tube passes into a furnace 22 in which it is heated by external heat to the melting point of copper and the overlapping portions welded. The heating may be effected by electric radiation, the heating elements being formed as a muffle 23. The tube then passes into a cooling chamber 26. Non-oxidizing gas may be supplied to the muffle 20 and the furnace 22 by a pipe 30. To render the coating smooth a film of carbon may be deposited on the article, preferably prior to the melting of the copper, as described in Specification 456,086.
