Title: Control means for fuel injection pumps for internal combustion engines
Inventor: MORRIS JOHN NEVILLE
IPC: F02D1/14
Filed: 1957-03-19
Abstract: 821,729. Regulating. S.U. CARBURETTER CO. Ltd. Dec. 23, 1957 [March 19. 1957], No 8931/57. Class 7(6) The idling mixture ratio of an engine supplied by a fuel injection pump controlled in accordance with the temperature and pressure of the intake air by a capsule 1 contained in an enclosure 2 placed in communication with. the intake pipe 1 at widely separated points 6, 7, by large cross section inflow and outflow ducts 4, 5, is controlled by means 8 actuated by the throttle valve control linkage 9 which at idling close the passages 4, 5, and submit the capsule 1 to a modified suction set up by a venturi 17. The pipe 4 includes a by-pass 13 with restriction 14 around the valve 8 and the pipe 5 includes a by-pass 15 around the valve 8 leading to a chamber 16 surrounding a venturi 17 in a passage connecting a point 19, immediately upstream of the throttle valve at idling, to the part of duct 5 downstream of the valve 8. An air bleed 11 into chamber 2 is controlled by a needle valve 10. During normal running the .valves 8 are set to open passages 4, 5, and the by-passes 13, 15, and air bleed 11 have a negligible effect on the control suction developed in chamber 2. At idling, with the valves 8 closed, air flows through passage 19 to set up a suction at the venturi throat 17 lower than that in the induction pipe 3 so that an air flow still circulates through pipes 4 and 5 via the by-passes 13, 15. By adjustment of the needle 10, the suction in chamber 2 can be varied from approximately that at the venturi throat 17 to a value above that in the induction pipe 3, permitting a wide variation in the idling mixture ratio without affecting the normal running conditions.

Abstract: 493,102. Mechanical switches without quick action. DENT, H., and OSMOND, C. E. March 30, 1937, No. 9036. [Class 38 (v)] [Also in Groups XL and XXXV] A selector unit, particularly for wave-band switching in an all-wave receiver, comprises a plurality of drum-like units mounted on a single shaft, rotation of which effects the circuit changes. The drums are divided into radial compartments by members 14, Fig. 2, which, together with the peripheral plates 13, constitute one unit segment of the drum, removable as a unit by removing two screws 17b, Fig. 1. Each segment carries a complete tuning coil 18, padder condenser 19c and trimmer condenser 19, the coil inductance and trimmer capacity being adjustable externally by screws 22, 19a. The coil is mounted on a base portion 21 formed in the plate 13, and has an adjustable iron-dust core. Rotation of the whole assembly effects connection between the contacts 24 on the drum and fixed flexible contacts 5. Each complete unit may also incorporate a switch 26e, h, j which may insert filter circuits in the aerial circuit and also carries a contact for switching from radio to gramophone reproduction, the high frequency circuits then being disconnected. A spring-ball click locating device 10, 11, 12 is provided. Specification 454,188, [Group XL], is referred to.

In a quick release two-part buckle 1, 10 for a safety belt or the like, the co-operating parts are so shaped that during the opening and closing operation, one part 1 pivots about the other 10 to give a toggle effect, whereby tension pin the belt will maintain the parts firmly in closed position, the reverse pivoting movement to open the buckle, being resisted by magnetic attraction between a permanent magnet 13 carried by one part and a co-operating member 5 of magnetic material on the other part. As shown, an end 3 of the part 1 includes a pin 2 by which it is attached to a link (not shown) to which the belt is adjustably secured, and the part 10 includes a slot 11 for the belt and a portion 12 for engaging the end 3 of the part 1. Pole pieces 14, 15 of the magnet 13 co-operate with the member 5 to prevent inadvertent, disengagement of the parts from the position shown, while permitting the buckle parts to be separated by upward pivoting movement of the part 1. Both parts are formed of aluminium alloy. In an alternative arrangement, a permanent magnet is used on each of the parts, one of the magnets being rotatable through 180 degrees related to the other when the buckle is to be opened.

Pattern plates.-Relates to machines for the manufacture of patterned tiles of the type in which a movable mould table co-operates with a series of feeding-devices for colour and for the body material and comprises improved coloursupplying devices. Colour from a hopper 12, Fig. 3, is passed by a rotary measuring-device 18 to a charger 14 reciprocated across a plate 15 by a lever 22 on a shaft 21 so as to transfer colour from the hopper to a counter-pattern 16 carried by the plate and co-operating with a stencil in the mould. A pivoted valve 20, counterweighted at 58, closes the hopper outlet 17 and is deflected by the engagement of the charger 14 with an arm 55. The plate 15 is movable vertically to lower the counter-pattern 16 into the mould and to raise it to permit of movement of the mould table, being suspended by brackets 31 and yoke 30 from a lever 27 carrying a roller 26 adapted to be engaged by a cam 25 on the lever 22 as the charger returns to the hopper. The drum 18 is furnished with grooves 19 and is rotated intermittently from the shaft 21 through lever and ratchet mechanism and interchangeable gearing. The Specification as open to inspection under Sect. 91 (3) (a) describes also the subject-matter described in Specification 205,096, and also the following :-A rotary table 1, Fig. 1, (Cancelled), carries moulds 2 successively beneath coloursupplying devices B<1> - - B<5>, a device D for body material, press E, and delivery means F. Intermittent movement is imparted to the table by a pawl 4, oscillated by a link 6 and crank 7, engaging table recesses 3. The table is locked by a spring bolt 10 engaging the recesses 3, the bolt being withdrawn by a cam 11 and lever mechanism. The operating-shafts of the devices B<@> ..B<5> are interconnected by bevel gearing and are oscillated from the shaft 9 through cam and lever mechanism. This subject-matter does not appear in the Specification as accepted.
