Title: Safety device operable by engine lubricant pressure
IPC: F01M1/24
Filed: 1973-03-09
Abstract: 1416473 Regulating I C engines; stopping engines I F VAN DER MERWE 9 March 1973 [16 March 1972] 11521/73 Headings F1B and F1K A safety device 10 for a liquid lubricated engine comprises a first member 28, 30 movable from a first position against the bias of a spring 58 by lubricant pressure acting through an inlet 70 and a second member 48, 52 which is movable from a first position against the bias of a spring 66 when a predetermined operation, e.g. engine starting or operation of the engine clutch or brake, takes place. A member 64 moved with the first member 28, 30 acts on balls 82, received in a recess 84 on the second member 48, 52 to lock the second member in a second position when the first member is in a second position. The spring 66 provides a greater biasing force than the spring 58 and when the balls 82 are released by the member 64 due to a fall in lubricant pressure both springs act to return the first member to its first position. The part 30 of the first member may act as a valve between a fuel outlet 24 and an inlet 26, apertures 42 and 46 providing a limited fuel flowpath when the second member is displaced from its first position. A relay (R), Fig. 6 (not shown), may be actuated to interrupt the power supply to spark-plugs (S) and operate a warning hooter by a contact bridging member (98), Fig. 3 (not shown), on the second member or a contact bridging member (102), Fig. 4 (not shown) on the first member. A time delay may be included in the relay circuit so that the relay is inoperable for a period after engine starting. The piston 52 of the second member may be subject to air-pressure by a piston 74 which is pressurized by a pneumatic cylinder (C), Fig. 5 (not shown), when a lever (L) is operated for engine starting or by pneumatic or hydraulic pressure from a brake or clutch master cylinder when the brake or clutch is operated. The pressure chamber 54 of the piston 52 may be supplied with air through a check-valve 80 and a bleed past the valve permits air to escape from the chamber over a period of time so that the spring 66 may return the piston to its first position if not locked in its second position.

Title: Liquid fuel pumps for internal combustion engines
Inventor: NICOLLS WILFRID EDWARD WALTER
IPC: F02M59/22
Filed: 1958-04-14
Abstract: 850,353. Fuel injection pumps. C. A. V. Ltd. April 13, 1959 [April 14, 1958]. No. 11734/58. Class 102(1). A fuel-injection pump comprises a rotating distributer and cylinder block which are movable axially of the housing to vary the quantity of fuel injected. In the embodiment shown in Fig. 1, a supply pump 12 actuated from the drive shaft feeds fuel to passage 25 which communicates successively with passages 24 in the rotary distributor 5. The piston 7 actuated by a cam 8 deliver the fuel past a non- return valve 21 and passage 22 to the lines 23 leading to the engine cylinders. An extension 9 of the distribute is splined on to the drive shaft and carries centrifugal weights 11 which move the shaft axially against an adjustable spring loading 31. The inlet passages 24 terminate in oblique grooves 24a and when the distributer is moved in one direction the grooves 24a connect the axial passage 20 with the inlet before the end of the pump delivery stroke and thus reduce the quantity of fuel injected. Alternatively the grooves 24a may be omitted in which case the movement of the distributer throttles the inlet feed to the pump and thus reduces the quantity delivered. The distributer may be moved by hand and the feed pump may be a gear or vane pump. In a modification, Fig. 3, the axial passage 20 extends beyond the passage 22 to a chamber containing a shuttle piston 33. The fuel feed passage 25 has a branch 37 communicating by a groove 36 and passage 35 with side of the shuttle piston 33 opposite the passage 20. The axial position of the distributer 5 determines the pressure acting on the piston 33 when the passages 24, 25 and 22, 23 are out of communication and this pressure moves the shuttle piston to the left until passages 24, 25 are in communication. During the subsequent delivery stroke the shuttle piston 33 is moved to engage an adjustable stop 34 before fuel is delivered, thus if the groove 36 is in full communication with passage 37 the piston 33 moves fully to the left and little if any fuel is discharged on the subsequent delivery stroke. If the groove 36 is out of communication with the passage 37 the piston 33 does not move to the left and a full delivery takes place subsequently.

Filed: 1925-05-08
Abstract: 261,051. Spence & Sons, Ltd., P., Llewellyn, W. B., and Crundall, S. F. W. May 8, 1925. Pigments.-A composite product suitable for use as a pigment comprises a titanium phosphate of the composition 3TiO2.P2O5.6H2O precipitated from a titanic salt solution in presence of an insoluble substance such as calcium or barium sulphate, which may be added as such or precipitated in the titanic salt solution. The precipitation of the phosphate is effected by adding the necessary amount of phosphoric acid or a phosphate, at a temperature not less than 50‹ C., to a solution of a titanic salt, such as chloride or sulphate, of a concentration not greater than that corresponding to 10 per cent of TiO2. The presence of free acid is desirable to keep impurities such as iron in solution, and the presence of chlorides, such as sodium chloride or hydrochloric acid, is beneficial to the form of the precipitate. The reagents may be mixed gradually in either order. Reference has been directed by the Comptroller to Specifications 195,181 and 206,284.
