Title: Improvements in or relating to fuel injectors for internal combustion engines
IPC: F02M61/20
Filed: 1963-04-20
Abstract: 1,081,084. Fuel injectors; stopping. E. G. F. PITTAR. April 20, 1964 [April 20, 1963], No.15652/63. Headings F1B and F1K. A fuel injector comprises a freely floating valve 8, the opening movement of which is limited by pneumatic, mechanical or electrical means. As shown the movement is limited by a diaphragm 14 subject on one side to the fuel supply pressure and on the other side to intake manifold pressure. The fuel is supplied by gravity or by a low pressure fuel pump through passage 21 and flows past the valve head 9 to a space in the nozzle tube 1 where ignition of part of the fuel expels the remaining fuel into the combustion space. Under normal running the pressure of fuel on the diaphragm is opposed by a spring 24 which is placed under compression upon energization of a solenoid 27 attracting armature 26 which carries the spring abutment 25. The travel of the valve 8 to the right is limited by circlip 15 thereon engaging a stop carried by the diaphragm 14 adjusted by intake manifold pressure supplied through pipe 23. De-energization of solenoid 27 removes the load of spring 24 and the fuel pressure acting on diaphragm 14 closes the valve to stop the engine.

Filed: 1943-09-24
Abstract: Heating a polyvinyl acetal in the presence of a monohydric alcohol-urea-formaldehyde resin so as to render the acetal heat resistant and reduced in solubility.  The two resins suitably compounded with plasticizers and pigments are applied to a fabric base and heated to effect reaction.  Polyvinyl butyral is the only acetal specified, while methanol-, ethanol-, n-butanol-and iso-butanol-, modified urea formaldehydes are the specified other resins.  Plasticizers (the sebacic and phthalic di-esters of mono-butyl ether of ethylene glycol-, dibutyl-, sebacate, -adipate-, phthalate; diamyl adipate; dicapryl phthalate; tricresyl or triphenyl phosphate; castor oil; cottonseed oil) siccative oils, alkyd resins and solvents (ethyl alcohol and acetate) may be added.  Fabrics may be coated with the product which may also be used in the preparation of such articles as ground-sheets, medical kits, sleeping bags, upholstery, umbrellas and many other specified articles.  The preferred use is for a coated fabric suitable for military raincoats. In examples: (1) polyvinyl butyral, and a solution of isobutanol-modified urea-formaldehyde resin in n-butanol, were dissolved in a mixture of ethyl alcohol and acetate and heated; (2) the same composition, but containing also the sebacic diester of monobutyl ether of ethylene glycol was similarly heated; (3) two coats of a polyvinyl butyral, n-butanol-modified-urea-formaldehyde resin in n-butanol, the phthalic di-ester of monobutyl ether of ethylene glycol, pigments and ethyl alcohol composition was applied to a cotton fabric, the solvent evaporated and further heating carried out. The final coated fabric was made into a raincoat; (4) the composition of (3) with the plasticizer replaced by the sebacic di-ester of monobutyl ether of ethylene glycol was used as in (3).

Title: Improvements relating to spray guns
IPC: B05B7/12
Filed: 1955-06-01
Abstract: 813,684. Sprayproducers. ANDREAE, E. C. June 1, 1956 [June 1, 1955], No. 15725/55. Class 69 (3). Liquid to be sprayed is fed to a chamber 1 in a gun body 3, and passes under the control of a disc-valve 17 through a bore 18 to a spring nozzle, and a Bourdon tube 30 within the chamber responds to the air supplied to the gun to control the valve. The spray nozzle comprises inner and outer members 10 and 8 respectively between which atomizing air flows to the spraying tip. The air is fed to a passage 22 in the gun body, and a proportion of it flows through a passage 26 to the interior of the Bourdon tube; the deflecting end of the tube is coupled by a pivoted link 33 to a link 35 pivoted at 36, and normally supports the valve 17 in the closed position. When air at a predetermined pressure is fed to the gun the Bourdon tube deflects and withdraws the valve from its seating and allows liquid to pass through a passage 19 and orifice 20 to the spraying tip. Instead of a disc valve, a ball or needle valve may be used.

Title: Improved means for converting continuous rotary motion into reversible linear motion
IPC: F16H25/20
Filed: 1929-05-21
Abstract: 333,927. Edwards, R. W., Young, J. D., and Young, S. D. May 21, 1929. Relay or power apparatus.-An arrangement adapted to be employed for steering a motor vehicle such as a tractor by the power of the engine comprises a sleeve nut adapted to be traversed on a fixed screw-threaded shaft by rotation through one or other of a pair of reversely driving gear trains put into engagement alternatively by means of clutches on the sleeve, the sleeve being connected to the arms or levers of the steering elements and only being operative so long as the clutch controlling the motion is held manually in engagement with a follow-up action. The screw-threaded shaft 11 is fixed, preferably in an oil bath, in a casing 8, one end fitting a squared socket 13, the other end 12 being bolted to the end wall 9. The sleeve 14, threaded thereon, is held by a yoke 23 in a frame comprising uprights 26, 32 and crossbars 25, and slidable, preferably on balls 29, between fixed guides 28, rods 55 attached to the frame passing through the end wall of the casing to the parts to be actuated. A power driven shaft 37, passing into the casing, carries, on a squared or splined extension 35, a bevel pinion 34 transmitting rotation through bevel gears 33, 30 to bevel wheel 18, loosely mounted on the sleeve 14, the gears 34, 33, 30 being carried by the frame together with an idler 56 for balancing thrusts. The bevel wheels 18, located between central collars 17 and plates 19 secured to shoulders formed by the reduced ends of the sleeve, are formed with annular flanges 21 which enclose friction clutch elements comprising rocker arms 43, Fig. 5, in which are seated rollers 46<1> adapted to engage the flanges when forced outwards by coned sleeves 46 on which adjustable studs 44 at the ends of the rocker arms bear. The rocker arms are mounted on pins 42 screwed into the plates 19 and also securing coverplates 21<1> in position. The coned sleeves 46 are simultaneously actuated through forked levers 48 pivoted at their lower ends 49 to the slidable frame, and at their upper ends engaging grooved collars 53 on a control rod 54 slidable in the cross bars 25 and passing to the outside of the casing. When the control rod is moved in either direction, one or other clutch is engaged causing the sleeve to travel in the same direction, thereby tending to overtake the, control rod and consequently to disengage the clutch in action as soon as the control movement terminates.

Title: Improvements in or relating to compressor units
IPC: F04B41/02
Filed: 1955-06-01
Abstract: 770,385. Compressors. PAPST, H. June 1, 1955, No. 15759/55. Class 8(1) In a piston pump compressor unit in which the piston pump 3 is connected with a circulation system 10, 11 through a delivery valve 7 and a suction valve. 5, a compensating chamber 8 is arranged between the delivery valve 7 and a second delivery valve 9 closing the circulation system and is connected to a point of the unit situated upstream of the suction valve by means of a restricted conduit 12. During normal operation of the unit the amount of compressed fluid passing through the restricted conduit constitutes only a negligible portion of the total quantity of pressure fluid, but when the pump comes to a standstill the conduit 12 permits of gradual pressure compensation between the chamber 8 and the crank chamber 6 so that there will be no back pressure when re-starting the pump. The conduit 12 may consist of a capillary, or a tube with an inserted plain or spirally wound core. The crank chamber 6 is constructed as a suction chamber and may serve as a lubricating oil reservoir, in which case the compensating chamber 8 is constructed as an oil separator and the restricted connecting conduit 12 serves as the oil return passage.

Title: Improvements in or relating to wireless antenna arrangements
IPC: G01S1/02
Filed: 1945-06-20
Abstract: 603,449. Directive radio systems. TAYLOR, D. June 20, 1945, No. 15790. [Class 40 (vii)] A directive receiving or radiating radio aerial, arranged for searching or scanning purposes, comprises means for oscillating the directive beam in a chosen plane over a limited sector, and means for causing the sector to change its angular direction in the same plane at a lower angular velocity, either by sweeping to and fro over a larger sector or by performing a continuous rotary movement. As shown, the system comprises a reflecting mirror 10 which is driven in an oscillatory motion about the horizontal axis 11 by means of the driving mechanism 12, so that the axis of the mirror is swept repeatedly over the angle x-y, and an aerial array 13 which is situated at or near the focus of the mirror: The array 13 is supported by an arm 14 and is driven to and fro between the limits 13a, 13b by means of the driving mechanism 16 so that, with the mirror in the position shown, the directive beam oscillates between the directions a and b. The limited sector a-6 consequently sweeps to and fro with the motion of the mirror, so that the whole sector x<1>-y<1> is repeatedly scanned. The mirror 10 may, alternatively, be made to rotate continuously about the axis 11 and also its angular velocity within the sector x to y may be made to differ from that within the sector y to x. In order to record the instantaneous position of the beam when the arrangement forms part of a radar system, the outputs from the Selsyn devices 17 and 18, controlled by 12 and 16 respectively, are compounded in a further Selsyn device 19, the output from which may operate voltage control means such as a potentiometer, or control the deflector coils associated with a cathode-ray tube display. As an alternative to the mechanical movement of the array 13, the beam oscillation may be obtained by electrical methods such as by varying the phase- or power-relationships between an array of dipoles or wave-guide horns. A form of phase-altering device suitable for use with the wave-guide horns is described in Specification 597,258.

Title: Improvements in lamp shades with a fabric cover
IPC: F21V1/00
Filed: 1931-05-29
Abstract: 376,442. Lamp shades. BRUCKMANN, H., 22, Papestrasse; and VARREN, A., 22, Klarastrasse, both in Essen, Germany. May 29, 1931, No. 15811. [Class 75 (ii).] The framework of a lamp shade with a fabric cover is formed of at least one wire or like support which at some part is inclined relatively to the two directions of the threads in the fabric, and the fabric cover is subjected to tensions at right-angles to one another and diagonally to the threads, so that the parts of the fabric between the supports are given a creaseless saddle shaped form. In the form shown in Fig. 5, the fabric cover 7 is cut obliquely as shown in Fig. 2, and formed into a cylinder by joining the two shorter edges 8, and is supported on the weak spring steel wire rings. 9, which have a rather larger diameter than the untensioned cover. The rings may be circular as shown, polygonal, or corrugated, or be bent out of the plane of the circle. In this last case they. are displaced relatively to one another. The tension vertically is produced by the weight of the shade, or may-be imparted by means of a forked rod 10 spreading both ends of the shade. In the form of Fig. 7, the wires 11 are bent helically, and the threads of the cover 12 extend vertically and horizontally, so that helical saddle-like channels are formed. The wires 11 are inserted in holes or eyes in end rings 13, or in small tubes on the rings 13. The rings 13 are shaped to correspond with the saddle-like surfaces. In the form of Fig. 10, the fabric is supported at the centre 16 by an electric bulb holder, for instance, and at the edge by a ring 13. A piece of fabric is subjected to such a tension that it expands more in directions inclined to the threads than in directions parallel to them, and is then trimmed to be made circular. The piece so shaped is secured at its edge to a ring 13 of somewhat smaller diameter. This form may be used as an upper and lower closure for forms previously described. The shade may be lined by extending the fabric and turning it back inside the closing ring, or, in the form of Fig. 10, sewing two pieces of fabric of the same shape together and inserting the ring 13 between them. A square piece of fabric may be placed over two bent wires forming a cross, and secured under tension. Shades for pedestal or small standard lamps may also be formed. Trimmings may be used to cover seams.
