Title: Improvements in or relating to window operating mechanism
IPC: E05F11/38
Filed: 1933-03-09
Abstract: 420,895. Sliding-window regulators. REVELLI DI BEAUMONT, M., 12, Via Giacomo Bove, Turin, Italy. March 9, 1933, No. 7212. Void [Abridged as open to inspection under Sect. 91 of the Acts, Sept. 11, 1933]. [Class 20 (iii)] The lifting lever 7 of a vehicle window is actuated by the engagement of a pin 8 thereon with a spiral groove 5<a> formed on a rotatable disc 5. The mechanism is supported by a pair of interconnected plates 1, 2, of which the plate 1 is secured to the vehicle door or body. The lever 7 is mounted on a pin 6 secured to the plate 2 and the free end of the lever is resiliently connected to the window V. The pivot pin 3 of the disc 5 is supported by both plates and passes through a casing 4 which encloses an automatic frictional locking device. The head 3<a> of the pin is adapted to receive the operating handle. The weight of the window may be balanced by a helical spring 9, the ends of whch are secured to the pin 6 and to the lever 7, respectively. In a modified arrangement, the window is raised by a pair of interconnected arms, one of which is provided with the operating mechanism described above,

Title: Improvements in turbopropeller engine fuel control systems
IPC: G05D23/22
Filed: 1956-03-08
Abstract: 808,920. Automatic temperature control systems. GENERAL MOTORS CORPORATION. March 8, 1956 [March 23, 1955], No. 7281/56. Class 38 (4). In a system for controlling a turbo-propeller, a valve responsive to electrical signals corresponding to actual and desired engine temperatures increases or decreases the fuel supply, a throttle control sets the fuel datum as well as varying the electrical signal corresponding to the desired temperature, and a device responsive to engine speed and throttle-control position replaces the variable signal by a fixed one. As shown, an engine-driven pump 16 receiving fuel from a conduit 14 supplies it through a conduit 18 to a gas-turbine 10 driving a variable pitch propeller 11. A controller 17 by-passing fuel from the output to the input of pump 16 through a conduit 28 is automatically controlled in accordance with engine speed through gearing 27. The datum of controller 17 is set by a throttle lever 24. To automatically control engine temperature a thermocouple 54, responsive to turbine inlet temperature, controls, through a thermionic amplifier 56, a reversible C.D. torque motor M adjusting a valve 30 by-passing a further quantity of fuel from the output to the input of pump 16 through a conduit 42. For any given position of valve 30 a venturi 50 controlling a valve 32 ensures that the second by-pass is a constant proportion of the fuel supplied through conduit 18. In flight, movement of a potentiometer 62 by lever 24 varies the temperature datum over a range determined by the setting of potentiometers 77, 79. For starting, taxiing and landing the lower settings of lever 24 close switches PS1, PS2 so that a relay system disconnects potentiometer 62 and substitutes one of potentiometers 83 according to whether engine speed is below or above a predetermined value at which a speed-responsive switch SS operates. Potentiometers 83 determine upper temperature limits at which motor M operates to reduce fuel supply, potentiometer 83 permitting a higher maximum temperature for the higher speeds. A rectifier 92 is connected to prevent operation of motor M to increase fuel supply at the lower settings of lever 24 or at speeds below the predetermined value. Prior to setting lever 24 to a position suitable for landing a switch LS is operated manually to apply an electromagneticallyoperated brake 60 to motor M so that valve 30 is locked in the position is has at the time. The datum position of valve 30 is determined by springs 40, 41, and the corresponding fuel flow is adjustable to suit different fuels by movement of a wall 31.

Title: Improvements relating to electric propulsion systems for ships
IPC: B63H23/24
Filed: 1936-03-11
Abstract: 456,488. Transmitting mechanical power. CROOK, H. N., and REBBECK, F. E., Queen's Island, Belfast. March 11, 1936, No. 7303. [Class 38 (iv)] [See also Group XXXVII] An electric ship propulsion system comprises two generator-motorrheostat assemblies, a divided generator field in each case being connected to its associated rheostat during normal use, whereas when one generator is out of use, the divided fields of the remaining generator and the two motors are connected for control to both rheostats. The port generator-motorrheostat assembly Gp, Mp, Rp and the corresponding starboard assembly are each self-contained during normal running when the switches 2, 3, 5, 6 are closed and the controller C is adjusted so that the row I of drum contacts engages the stud contacts A. The fields Fm of the motors are then regulated and reversed by the adjustment of the movable constacts of the rheostat over resistances R2. The fields Fg1, Fg2 of each generator are then supplied in parallel from mains B through rheostat resistances R1. If the starboard generator G3 is cut out by adjustment of the drum controller to position II and used for some other purpose, switches 2, 4, 7 are closed so that the armature circuit of the port generator Gp and of the two motors are in series. The motor fields Fm are then reversed and controlled each by its corresponding rheostat through resistances R3, an additional resistance R4 being introduced into each circuit. The two field windings Fg1, Fg2 of the generator Gp are then controlled respectively by resistances R1 of the port and starboard rheostats. When controller C is adjusted to position III, the port generator is similarly cut out. A variable rheostat R5 controls the field of whichever generator is cut out.

Abstract: 1358475 Image pick up tubes ENGLISH ELECTRIC VALVE CO Ltd 16 Nov 1972 [17 Feb 1972] 7353/72 Heading H1D A camera tube comprises a wall anode connected to an external terminal and a mesh electrode disposed in front thereof, two diametrically opposed conductors extending therefrom to a further terminal external of the tube envelope, and fusible means 7, 8 internal of the envelope provided to electrically connect the wall anode to the opposed conductors, whereby the tube after completion of manufacture, may be converted from a tube exhibiting characteristics of the integral mesh type, Fig. 1 (not shown), to a separate mesh type, Fig. 2 (not shown) by fusing the fusible means. Preferably the fusible means is two thin Pt strips, conversion being by passage of current via terminals 3, 4. Further fusible means 9 of greater current carrying capacity is fused by RF heating after manufacture while leaving the first means intact. Where an integral mesh tube is required, strip 9 is fused to break open the loop of conductors 5, 6 to inhibit inductive pick up. Reference is made to prior art opposed conductors minimizing "line scan pick up" by rotation of tube to achieve cancelling, the above construction eliminating the requirement of use at a particular orientation.

Filed: 1917-05-24
Abstract: 113,051. Atkinson, J. S., and Stein & Atkinson. May 24, 1917. Lifting-dogs.-In the manipulation of ingots, more particularly in connexion with furnaces and rolling mills, a gripping and transporting device lifts the ingot and delivers it to a rising and falling table or support which lowers the ingot on to transporting rollers and simultaneously turns it through an angle. The first device consists of a pair of gripping arms 8 pivoted together at 9 and carried by a depending support 7 from an overhead carriage 4. The connexion between the arms 8 and the support 7 is made bv blocks 11 which are longitudinally movable relatively to the arms, and are pivoted in a crosspin carried by a pin 10 rotatably mounted in the lower end of the arm 7. In operation the gripping jaws are positioned to embrace the ingot and the carriage 4 is then moved to slide the blocks 11 along the arms 8. A firm grip is thus obtained and the ingot can be lifted and transported. The table or framework 13 is operated by a hydraulic cylinder 15 the ram of which carries a projection 17 engaging a cam groove 16. As the table' is lowered, it turns through a right angle so that the ingot is brought into position for transfer to a roller way 2.
