Title: Improvements in and relating to electric fluorescent lighting systems
Inventor: MANDL ARTHUR
IPC: H05B41/40
Filed: 1950-07-17
Abstract: 715,466. Supply and switching systems for space discharge apparatus. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. July 4, 1951 [July 17, 1950], No. 17841/50. Class 38(4) A D.C. supplied fluorescent lighting system comprises the combination' with a switch 4 for reversing the connections of supply conductors 2, 3 to one or more lamps 1, of a thermal system comprising temperature responsive means associated with a mass 7 having an electric heating coil 6 the temperature responsive means being operable in response to two predetermined temperatures of the mass to control the actuation of the switch 4 to its two positions and to control the heating coil 6 to alternately heat and cool the mass between the predetermined temperatures with a time delay dependent upon the thermal capacity of the mass. As shown, the means comprise positions 8, 9 which cyclically shunt the series arrangement of the heating coil 6 and the switch operating coil 5, these being in series with lamp(s) 1 across the reversing switch output. The switches 8, 9 may close when the mass temperature rises to 150‹C and 50‹C respectively. In operation, e.g. on falling temperature, switch 9 and reversing switch maintaining contacts 4a shunt the series combination 5, 6 so that the switch 4 remains biased to the "normal" position. On reaching 50‹C switch 9 opens, the coil 5 is energized to reverse the switch 4 and open contacts 4a, and coil 6 heats the mass to 150‹C whereupon switch 8 closes to revert switch 4 to its normal position, and the sequence continues; the mass 7 is lagged and the temperature limits are so chosen in relation to the supply voltage that the periods of heating and cooling, i.e. of lamp current flow in each direction, are substantially equal. In a modification, the heater coil 6 is serially connected with contacts 4a directly, or through a potentiometer, across the supply, and switch coil 5, in series with a parallel arrangement of switches 8, 9, is similarly connected to the supply.

Patent GB-585566-A (GB)
Title: Improvements in and relating to processes for purifying oils
IPC: C11B3/00
Filed: 1939-06-20
Abstract: Cooking or frying oil such as olive oil, peanut oil or cottonseed oil which has been used for cooking fish for tinning is purified by emulsifying with water, which may be slightly acid or alkaline and then mechanically separating into a purified oil phase and a stable emulsion containing the fish fat impurities. In an example, peanut oil containing 4 per cent. of sardine fat, which has been used for cooking sardines, yields after emulsification and separation 92 per cent. of a limpid and clear oil containing 0.25 per cent. of sardine fat suitable for further cooking operations.  The used oil may be subjected to preliminary treatment with steam, which may be superheated, and the emulsion may be formed by atomizing the oil with steam and condensing the bulk of the mist so formed while volatile foreign substances are carried away with the excess steam.

Title: Arrangements for increasing the sensitiveness of alternating current instruments
IPC: G01R15/08
Filed: 1928-06-21
Abstract: 293,387. Siemens - Schuckertwerke Akt.-Ges., (Assignees of Siemens-Schuckertwerke Ges.). July 5, 1927, [Convention date]. Current and pressure meters.- The sensitiveness of an alternating-current measuring-instrument or relay, Fig. 2, is increased by connecting in series therewith an iron-cored inductance coil 3, the instrument 2, in series with the inducance 3, being connected across a low - resistance shunt 5 in the main circuit 4. Resistances, inductances, or capacities, or combinations thereof, may be associated with the instrument. The measuring or relay circuit, or the hole circuit, may be tuned to the frequency of the supply voltage by adding a condenser. Harmonics developed in the iron core of the inductance are thereby suppressed. Transformers may be interposed between the instrument and the inductance. The Specification as open to inspection under Sect. 91- (3) (a) states also that a voltmeter 2, Fig. 2 (Cancelled) may be similarly connected in series with an iron-cored inductance 3, and also that two capacities or oscillation circuits may be connected in parallel, so as to form a short-circuit for high-frequency oscillations. This subjectmatter does not appear in the Specification as accepted.
Patent GB-1461573-A (GB)
Title: Fuel injection pumping apparatus
IPC: F02M41/14
Filed: 1973-04-14
Abstract: 1461573 Fluid-pressure servomotor systems C A V Ltd 21 March 1974 [14 April 1973] 18096/73 Heading G3P [Also in Division F1] In fuel injection pumping apparatus of the kind having an injection pump with a fluid operated timing control member 39 and a shuttle 19 operable during the filling stroke of the pump to displace fuel from a bore into the pump working chamber 11, the shuttle is provided with a groove 60 which co-operates with ports 61, 62 in the wall of the bore to establish a pressure in a conduit 45 which is related to the stroke of the shuttle, the pressure in the conduit 45 being used to control the timing control member 39. The conduit 45 is connected between the port 61 and a restrictor 63 fed by a valve controlled feedpump 25 having a speed dependent output. As the stroke of the shuttle 19 increases so does the degree of registration of the ports 61, 62 with the groove 60 and hence an increasing amount of the fuel supplied through the restrictor 63 escapes to a drain connected by a restrictor 64 to the port 62. Thus the speed dependent pressure supplied to the conduit 45 is modified in relation to the shuttle's stroke and since the latter is indicative of the quantity delivered and therefore the load on the engine supplied by the pump, the timing control member 39 is supplied with pressure which is a function of both speed and load. Pressure in the conduit 45 acts on a servopiston 38 which in turn controls the position of the timing control member 39. A metering valve 33 having a rod member 41 which takes up a balanced position in a sleeve 40 dependent on the forces applied thereto by centrifugal weights 43 and operator adjustable springs 53, 54 determines the amount of fuel supplied through passages 27, 21 and a rotary valve 22 to the delivery end of the bore containing the shuttle 19. The maximum stroke of the shuttle 19 is determined by a cam surface 34 on a spring-loaded piston 35. Axial movement of the piston 35 is effected by pressure in a passage 36, the pressure being derived from an axial bore 46 in the rod member 41 which receives pressure from the feedpump 25 and has a spill port 51 controlled by a valve 52. Because the valve 52 is loaded in effect by the force due to the weights 43 the pressure established in the bore 46 is proportional to the square of the speed. Rotary valves 20, 22, 24, 23 control the filling and emptying of the shuttle bore.

Filed: 1966-04-26
Abstract: 1,147,781. Rotary positive-displacement pumps and motors. WEBSTER ELECTRIC CO. April 26, 1966 [May 4, 1965], No.18271/66. Heading F1F. A rotary positive-displacement pump, or motor, of the externally-meshing gear type comprises a pair of gears 16, 18, Fig. 2, lodged in a housing 12 between a fixed wear-plate 64 and an axiallymovable wear-plate 62 having a resilient sealing- means 72 attached by e. g. bonding, to the face thereof that is farthest from the gears so as to define with the housing a pressure-loading chamber 30 having a high-pressure portion or region 70, Fig. 6, and a low-pressure portion or region 74, radially-inward distortion or extrusion of parts 72C, 72D, 72E, 76A of the means aforesaid being prevented by a thin flanged-plate (90), Figs. 8, 9 and 10 (not shown), which contains an aperture 90G in a portion 90A for admission of working fluid to the portion 74 of the chamber 30. The plate 62 has portions 62D on the low-pressure side of its periphery pressed against the housing by the fluid in the portion 70 of the chamber 30, most of the remainder of its periphery being cut back to minimize friction between the plate and the adjacent ends of the gears and to give the working fluid on the high-pressure side of the gears access to the said portion 70. Initial loading of the plate 62 is effected by the resilient sealing-means; and leakage across the tips of the gear-teeth is minimized by the gears being pressed against the housing on the low-pressure side by the fluid on the high-pressure side, the radial forces thus acting on the gears being increased by the provision of recesses 28B in the housing. The portion 74 of the chamber 30 may be partially filled by a plate (92), Fig. 11 (not shown), which is separated from the plate (90) by an arcuate resilient-rib 94, the purpose of the plate (92) being chiefly to prevent inward distortion or extrusion of the sealing means by the working fluid in the parts of the portion 70 adjacent the portion 74. The parts 72D of the sealing means abut the outer races of needle-roller bearings 34, 38 for shafts 32, 42 carrying the gears. In operation of the machine as a pump, the working fluid enters a chamber 28 containing the gears through an inlet (50), Fig. 5 (not shown), and is subsequently ejected from said chamber through the beforementioned portion 70 of the chamber 30, passages (52A to 52D) and an outlet (52).

Title: Improvements in or relating to photographic roll film cameras
IPC: G03B19/04
Filed: 1954-06-22
Abstract: 764,890. Photographic cameras. HEIDECKE, R., and FRANKE, H., [trading as FRANKE & HEIDECKE FABRIK PHOTOGR PRAZISIONS-APPARATE]. June 22, 1954 [Aug. 17, 1953], No. 18273/54. Class 98(1) In a photographic twin lens reflex camera adapted for use with perforated kinematograph film or normal roll film, the same metering device is used for either type of film by employing a metering roller over which the film passes having a central portion 8 of width equal to the kinematograph film and end portions 7 of larger diameter for use with normal film the circumferences being proportional to the respective frame lengths of the films so that for every frame advanced, a disc 13. geared to the metering roller by gears 11, 12, makes one revolution whatever the film. In the position shown, one frame length has been advanced, the latch 22 pivoted to bar 20 is in engagement with the locking wheel 4 to lock the winding mechanism, and a projection 19 on bar 20 is in engagement with a notch in disc 13. When the shutter release 28 is depressed, the projection 31 on the web 29 engages the bar 23 and moves the slide bar 20 downwards. The pin 24 on the bar 23 is thus released from the path of a locking lever 25, which then pivots under the action of spring 27 and bears against the sloping edge 33 of the web 29. As the web rises again, after exposure, the locking member 25 moves into the slot 34 and locks the shutter release, and this is not unlocked until the bar 20 moves upward again when the next frame has been wound on and the pin 24 moves the lever 25 out of the notch 34. As the bar 20 is moved downwards during release of the shutter, the projection 19 is sprung behind a lug 18 on the latch 16 which is urged in a counter-clockwise direction by spring 17. The disc 13 is then free to rotate and as the film is wound on, a pin 14 on disc 13 rocks the latch 16 and releases the projection 19, but bar 20 is only permitted to move upwards a little way under the action of spring 21 since the projection 19 is arrested by the edge of disc 13. It is not until the frame is fully wound on that the notch in disc 13 comes opposite the projection 19 which is then permitted to move upwards into the position shown, and bar 20 rocks latch 22 to lock the film wind. Provision is made for unlocking the film winding mechanism when the back of the camera is opened by a slide 37 which normally bears against the camera back under the action of a spring 36, but moves to the left when the back is opened, and the sloping edge 38 acts on a pin 41 and forces the bar 20 downwards.
