Title: Improvements in or relating to fuel injection systems for internal combustion engines
IPC: F02M51/00
Filed: 1956-02-07
Abstract: 820,568. Valve gear; starting fuel injection engines. MILLEVILLE, W. M., J., DE Feb. 7, 1956 [Feb. 15, 1955; July 16, 1955], No. 3864/56. Class 7(3) and 7(6) An electromagnetically operated fuel injector 22b, Fig. 9, fed with fuel under constant pressure at 17b, is controlled by a distributer 29b having a control surface Mb which co-operates with a contact 34b adjusted in accordance with engine speed to vary the period of injection. The lift of the needle valve 22b is controlled by an adjustable abutment 64 co-operating through a rod 63 with the end of a spring- loaded abutment member 62 connected to the upper end of needle 22b. An upper solenoid 56 is permanently fed with current from a battery 58 and the needle valve 22b is lifted when a second solenoid 59, mounted on a member 60 attached to the needle valve and arranged to produce an opposite field to that of solenoid 56, is energized under the control of the distributor 29b. The brush 34b is also connected through normally open switch 69 to an ignition coil 11b feeding a sparking plug 9b for ignition at starting. To start, the brush 34b is moved to the end of distributer 29b out of contact with the surface 17b and the engine turned over, after which the brush is returned to operative position and switch 69 closed. When the brush contacts the surface Mb the fuel injector is operated to supply fuel and upon breaking of the circuit of the coil 59 the ignition coil 11b produces a spark at the plug 9b to ensure ignition. After starting, the switch 69 is opened to render the sparking plug inoperative. The distributer 29b comprises a conducting cylinder covered with insulating material except at the part Mb, the shape of which is calculated to produce a desired variation in fuel injection as the brushes 34b connected to the injectors are moved axially in accordance with engine speed. A second control surface may be provided, the brushes co-operating with both control surfaces being adjusted together. In a modification, Fig. 10, the ignition coil is connected by lead 74 to a contact 73, on needle valve abutment member 63c, co-operating with a contact 72 connected in the circuit of coil 59c, which contacts form the make-andbreak device of the ignition coil. In Fig. 6 a modified distributer device comprises a conducting disc 28 covered with insulating material except over a control surface N with which co-operates a brush 33 slidable in response to varying speed along a diameter of a disc to vary the injection. In a modified injector, Fig. 2, the upper end of the needle valve 22 carries an armature which is actuated by a solenoid 3.

Title: Improvements in or relating to circular knitting machines
IPC: D04B9/06
Filed: 1936-02-08
Abstract: 470,020. Knitting. BENTLEY ENGINEERING CO., Ltd., WAINWRIGHT, C. H., and BUSWELL, G. A. Feb. 8, 1936, No. 3892. [Class 74 (ii)] A machine of the superposed-cylinder type is provided with an adjustable verge which can be moved into a lower position, as required for rib knitting, while permitting the yarn ends, resulting from yarn-changing operations, to be turned to the inside of the needle circle. The verge consists of an inverted cup - shaped member 8, fitting within and adjustably axially of the rib needle cylinder 2 and a piston-like inner member 10. Hooked bits 14 are held in place by the radially tricked lower edge 12 of the member 10 and a retaining plate or ring 16. The upper edges 28 of the bits are housed in the tricked lower edge 24 of the member 8. The members 10, 8 are adjustable vertically by two coaxial tubes 36, 30, which are independently movable downwards against the pull of springs 31, 40 under pattern control. While a ribbed fabric is being knitted, the members 10, 8 are held apart sufficiently to disengage the bits 14 from the tricked edge 24 of the member 8. The yarn ends resulting from yarn-changing operations can thus be passed, through the apertures thus provided, to the inside of the needle circle. To provide further space, several adjacent bits may be removed from the part of the needle circle where the yarn ends are to be turned in. Specifications 220,355 and 301,350, [both in Class 74 (ii)], are referred to.

Title: Improvements in stop and like valves
IPC: F16K1/48
Filed: 1921-02-02
Abstract: 179,297. Wagner, F. Feb. 2, 1921. Fluid-actuated valves; liftvalves; spindles. --In valves in which the valve member is provided with a detachable connection to its spindle within the valve casing the connection is constructed in the form of radially displaced balls adapted to be moved towards or away from the valve spindle. The arrangement shown in Fig. 2 comprises a main lift valve 1 and a pilot valve 2 in which the main valve is rigidly connected to the spindle 8 whilst in the open position, as shown, by the inward displacement of the balls 7, 9 into engagement with the reduced jnder part of the spindle member 11. As the valve is being closed the balls 7, 9 are displaced outwardly by the enlarged upper part of the member 11. and enter the enlarged recess at 10; a rigid connection of the valve 1 to its spindle is thus provided for all positions of the valve. Various arrangements and dispositions of the balls may be adopted and the values may be operated bv screw mechanism or by levers in conjunction with links or cords. Fig. 7 shows a screw-operated valve in which an inner locking spindle 23 can be raised in an emergency by a forked lever 25 thus releasing the ball connection and allowing the valve member to close down by gravity and the pressure of the controlled fluid. Fig. 9 shows a similar arrangement provided with a fluid-operated piston device 28 to enable the valve to close automatically in the event of a breakage of the steam outlet pipe. In normal operation the piston is subjected to equal pressures on the upper and lower side, and is in its lower position, as shown. If a breakage occurs the upper side of the piston is relieved of pressure so that the piston rises; the balls 30 thereupon effect connection with the spindle 27 which is raised and carries with it the inner spindle 23. When the reduced portion breaches the balls 20 these move inwards and release the valve 21 which thereupon closes. To re-open the valve the main spindle must be screwed down and the inner spindle lowered to re-engage the valve member 21 by the ball connection 20.

Title: Improvements in or relating to apparatus for colour television
Inventor: HILL FRANK LAWRENCE
IPC: H04N11/00
Filed: 1951-02-22
Abstract: 719,059. Colour filters. CINEMA-TELEVISION, Ltd. Feb. 22, 1952 [Feb. 22, 1951], No. 4305/51. Class 97(1) [Also in Group XL(b)] A colour filter assembly for television apparatus comprises a set of transparent colour filters 1-6 each pivoted at one end to a disc 8 and at the other to a ring 9. As the disc and ring rotate each filter strip in tunr passes across the optical path which is symmetrically disposed about the centre of ring 9 as indicated by the outline 10. When employed in a cathode-ray tube receiver, the assembly is driven at a speed such that the filters traverse the optical path at the field scan rate with the bottom edge of each filter traversing the path just ahead of the scanning line. In the case of transmission, the operation is similar, but in order to expose the photo-sensitive storage surface for the longest possible period, the trailing edge of each filter traverses the optical path immediately after the scanning line. To prevent white light falling on the photo-sensitive surface during the passage of the gaps between successive filters, the assembly is operated in conjunction with a synchronously driven shutter of similar construction but having narrow opaque strips in place of the filter strips. Alternative arrangements which avoid the interfilter gaps comprise two filter assemblies either rotating in the same direction, Fig. 5 (not shown) or in opposite directions, Fig. 6 (not shown). Specication 676,907 is referred to.
