Abstract: 385,650. Filing papers. SIMMONDS, W. J., 32, Pelham Road, Wimbledon, London. July 18, 1931, No. 20626. [Class 146 (i). ] A file for storing papers comprises rigid hollow posts e adapted, when firmly secured to a baseplate b, to enclose means for binding papers filed thereon, the posts being detachable so that the binding means with the papers stacked thereon may be withdrawn from the baseplate. As shown in connection with files comprising posts e co-operating with pivoted arches a, the posts e may be screwed into sockets in the baseplate b, or lugs attached thereto, or may be held in slots g in the baseplate b by wedge-members h operated by finger-levers i which are held in either extreme position by springs k. The posts e are placed over two U-shaped metal strips m previously inserted in position in the slots g. In order to remove the papers from the file, the posts e are released and removed together with the strips m and papers. By sliding off the posts e, the papers may be bound by bending over the ends of the strips m. An ordinary paper-fastener may be used in place of the strips m.

Patent GB-1507487-A (GB)
Title: Nuclear fuel element
IPC: G21C3/20
Filed: 1975-05-16
Abstract: 1507487 Fuel elements GENERAL ELECTRIC CO 16 May 1975 [24 June 1974] 20828/75 Heading G6C A fuel element 41 comprises a metal liner 24 positioned in the gap between the fuel pellets 16 and the cladding 17, the liner 24 having a coating 25 containing at least one additive on its surface adjacent the fuel pellets 16. Instead of the continuous coating 25, the liner 24 may have a coating formed of a multiplicity of longitudinal strips (Fig. 3, not shown). The liner 24 is formed of Zr, Mo. W, Rh, Nb or an alloy thereof and can be fabricated from foil by welding thin sheet to form the hollow cylindrical shape, or extruded from stock. One type of additive serves to affect the nuclear characteristics of the fuel and may comprise Pu-239 or U-235 for enrichment purposes or comprise a burnable prism such as Gd or B. Alternatively, the additive or additives may serve to control the fuel chemistry, for example ceramic additives such as Si or Si-Al 2 O 3  may be used as getters for fission-produced Cs, or Nb may be used for the control of O 2  potential. Yet again, the additive or additives may serve to impart to the fuel periphery a thin plastic layer with a high creep rate, and this would reduce or eliminate localized stress in the fuel element during reactor operation. Various methods of coating can be used including mixing the additive or additives with an adhesive formulation for coating on the liner, for example as a glaze. Alternatively, electroplating, metallizing, pyrolysis, arc-plasma spraying, vapour deposition, or electrophoresis can be used.

Title: Improved control system for electro-motive traction
IPC: B60L50/11
Filed: 1952-08-21
Abstract: 703,604. Control of D.C. motors. GENERAL MOTORS CORPORATION. Aug. 21,1952 [Sept. 13, 1951], No. 20970/52. Class 38(3) An electro-motive traction control system comprises an engine-driven generator G which has a plurality of excitation windings and is connected to a number of traction motors M1-M4. Wheelslip responsive relays WS14 and WS23, effective in response to unbalanced current conditions between the motors, are adapted to reduce, by means of a delay relay, the excitation current in the generator field windings in a sequential manner, by the reduction of one winding current immediately and another winding current after an appreciable time interval. A battery switch BS and a series switch S are initially closed so that the series contactors S14, S23, are energized to connect the traction motors in series-parallel. A relay ORS is energized to override governor GOV and cause movement of generator field rheostat FR to its increasedresistance position, and, upon closure of switch CSI, a generator shunt field relay SHR closes to short-circuit discharge resistance SD. A relay BR is then energized to de-energize solenoid ORS and to connect a battery-supplied field winding BF of the generator in series with field rheostat FR so that the governor GOV now controls the supply of fuel to engine E as well as the field rheostat. The traction motors may be either manually or automatically connected in parallel by closure of switch P. In the event of wheel-slip one of the relays WS14, WS23, becomes effective to actuate relay WSCR and disconnect relay BR the dropping of which is delayed by means of resistor R5. A resistance R6 is immediately placed in series with generator field winding SH, and, when the relay BR drops, solenoid ORS moves the field rheostat FR towards its increased-resistance position, so as to reduce the generator current upon re-establishment of the circuit. A discharge resistance BD is shunted by contacts of relay WSCR, so that the dropping of relay BR causes a discharge current to be sent from generator field winding BF through rectifier SR and the generator voltage is decreased at a controlled rate.

Title: Carrier positioning system
IPC: B41J19/20
Filed: 1975-09-11
Abstract: 1510135 Carrier positioning system BURROUGHS CORP 11 Sept 1975 [15 Nov 1974] 21085/77 Divided out of 1510134 Heading G3R [Also in Divisions G4-6] The disclosure is the same as that in Parent Specification. The claims are directed to a control system for keeping a print element carrier 15 at a predetermined speed. An electro optical tachometer 35, 37, 39 generates pulses at a rate proportional to the speed of the D.C. motor 29 driving the print element carrier 15. A counter 309 described in detail, Fig. 13 (not shown), is pre-settable with a count indicating the predetermined speed and counts clockpulses inbetween tachometer pulses which reset the counter. Depending on the count achieved, an underspeed or overspeed signal is generated. In case of overspeed, the flow of current through the D.C. motor is temporarily stopped till underspeed is detected again. In case of underspeed, a current is caused to flow through the motor till overspeed is detected again. Thus the predetermined speed is kept relatively constant.

Abstract: 1424094 Jet propulsion nozzles - variable area ROLLS-ROYCE (1971) Ltd 3 April 1974 [4 May 1973] 21204/73 Heading F1J The invention relates to a variable area nozzle for a gas turbine jet engine which comprises an annular series of flaps 19 pivotally mounted at their upstream ends at 20 to fixed nozzle structure 18. An axially movable cowl 21 is disposed around the assembly of flaps being movable by means of a plurality of air motors 27 each driving a ball-screw 26 which engages a nut 25 secured to the cowl. The cowl is so shaped that in the downstream position Fig. 2 the flaps 19 are pivotally moved to the maximum area position by the pressure of the exhaust gas discharging through the nozzle. As the cowl is moved in an upstream direction to the Fig. 3 position the cowl bears against the flaps to pivot them inwardly to the minimum area position. The cowl is formed with an internal cavity 22 to which air under pressure from the engine compressor is supplied through duct 23; the cowl is formed with a circumferentially-extending slot 24 whereby air under pressure from the cavity may pass from the cavity to the space between the cowl and the flap members 19 so as to constitute an air bearing.

The liquid fuel burner arrangement for a vehicle heater includes a burner 13 located within a combustion chamber 14 of a firepot 15 and surrounded by a radiation baffle 20, the burner being supported on the end of a vaporizing tube 45 containing a mesh screen 56 and fuel being supplied through an inlet 46 by a pulse type pump and combustion air being delivered by a high-pressure blower 47 so that fuel spreads on the screen 56 and heat from flue gases passing through a passageway 43 and chamber 57 assists in vaporization of the fuel. In operation fuel supplied by the pump passes in liquid form to the vaporizing chamber 58 of the burner, through a drip tube 73 to burner chamber 59 and thence through a second drip tube 75 and on to a glow plug igniter 76, the ignited fuel causing vaporization to commence so that combustion in burner orifices 69 generates a blue flame which impinges on the baffle 20. A coil heat-exchanger 28 through which water flows provides heat for the vehicle and a temperature-responsive switch 79 in the flue gas stream de-energizes the glow plug 76 when ignition takes place.
