Abstract: 549,382. Two-stroke engines ; cylinders; cooling &c. JACKSON, L. MELLERSR-. (McCarthy, M. E.). July 24, 1941, No. 9396. [Classes 7 (ii) and 7 (vi)] In an engine having a plurality of  cylinders 17 with inlet ports 31 and exhaust ports 42 at opposite ends controlled by corresponding ports 40, 41 in sleeve valves 33, the intake air is admitted by scoops 70 into cup-shaped cylinder heads 34 ribbed at 35, and thence into an air chamber 19, which may be formed between the crank case 20 and a cover 22 arranged between rows of inverted V-cylinders, the air passing from the chamber 19 to inlet chambers 28 -surrounding the inlet ports 31. The air is drawn into the chamber 19 and through an opening 77 to superchargers 78, 79, which discharge it by passages 82, 83 to the chambers 28. The superchargers are driven through gearing 92...96 from the propeller shaft 90, which is driven from the crankshaft 11 by gearing 104, 108. The cylinder heads 34 may be fixed, or may move with the sleeve valves. Water jackets 48 are in circuit with a pump P and radiator R by means of pipes 53, 53<SP>1</SP>, 54 leading to manifolds 50, 51, the former of which are ribbed at 115. Similar ribs may be provided on a lubricant reservoir 110. Fig. 6 shows a modified arrangement of the pump and radiator. Lubricating oil is blown from the sleeve ports 40 through minute orifices 121, when these are uncovered by the pistons 45. Fuel pumps 62 supply injectors 60, also controlled by the sleeve ports 41. The cylinders are formed with a longitudinal rib serving as a baffle to direct the charging-air uniformly around the inlet ports 31. The open ends 15 of the cylinders are formed in the crank case, the cylinders 17 being centred therein by rings 26, which may be rotated to regulate the effective area of the ports 31. The sleeve valves are reciprocated by connecting-rods 36 forked to engage the ends of the sleeves, to which they are attached by wrist pins 37. The crank case is made of aluminium or other light metal, and the cylinders 17 of cast iron. The connecting-rods of one row of cylinders are master rods, to which the connecting-rods of the other row are pivoted.

Patent GB-1469164-A (GB)
Title: Timed pulsed fuel injection apparatus and method
IPC: F02D3/00
Filed: 1974-03-04
Abstract: 1469164 Liquid fuel injection systems S RHINE and M R SHOWALTER 4 March 1974 [8 March 1973] 9650/74 Heading F1B A fuel injection system comprises pump P which supplies fuel through valve V to an accumulator Ch 1, which discharges through rotary valves L 1  and L 2  into transfer accumulator Ch 2, which in turn discharges in sequence into each of a plurality of nozzle accumulators Ch 31, Ch 32, &c. The transfer accumulator is in fluid communication with either Ch 1 or one of the nozzle accumulators, but is never in communication simultaneously with both Ch 1 and a nozzle accumulator. Accumulator construction. Each accumulator consists of a rigid metal tube with holes in its walls and an elastomeric sleeve 2 secured at its ends by clamps 3 and 4. When fluid-pressure in the tube increases to the point at which the force exerted by the fluid exceeds the radially inward force due to the circumferential tension in the sleeve, any further increase in pressure results in expansion of the sleeve and an increase in the volumetric capacity of the accumulator. The injection system comprises a pump P which supplies fuel through a valve V to an accumulator Ch 1. The pressure drop across valve V is kept constant by a by-pass valve 24 mounted on a diaphragm 5 which is subject on its opposite surfaces to the pressures upstream and downstream of valve V. A relief valve 10 vents excess pressure. Accumulator Ch 1 is connected through rotary valves L1 and L2 to accumulator Ch 2. The path through valve L2 is always open and is shaped so that the flow-path between accumulators Chl, Ch2, and Ch31-Ch38 does not vary, regardless of which injector is receiving fuel. Fuel from accumulator Ch 2 is fed to a distributer L3 which successively connects with each of the accumulators Ch 31- - - - - - Ch 38. The relative angular positions of the rotary valve L1 and the distributer L3 are such that there is no communication between accumulators Ch 1 and Ch 2 during the time periods when accumulator Ch 2 communicates with any one of accumulators Ch 31 ---- Ch 38. Similarly, accumulator Ch 2 communicates with accumulator Ch 1 during the time periods when accumulator Ch 2 is not in communication with any of accumulators ' Ch 31 - - - Ch 38. Each of the last-mentioned accumulators is connected to an injection nozzle through a variable-area needle valve which controls the rate of flow through its associated nozzle so that the maximum flow-rate is quickly established, the fuel flow per degree of crank rotation then remains constant during the injection period and fuel flow is then terminated abruptly.

Title: Improvements in or relating to jacks
IPC: E04G21/12
Filed: 1949-04-09
Abstract: 690,986. Wire strainers. STRESSED CONCRETE DESIGN, Ltd. April 5, 1950 [April 9, 1949], No. 9706/49. Class 45 Relates to a jack device in which an outwardly directed thrust force exerted by a hydraulic or pneumatic jack upon a crosshead 5 at one end of the jack is transmitted by a pair of links 20 to a stressing member 10 extending transversely of a thrust framework 3, against which the other end of the jack is supported, the ends of the links 20 which are adapted to be connected to the stressing member being formed with loops through which the ends of the stressing member respectively project, the front edges of the stressing member having recesses 12 into which the closed ends of the loops fit to prevent disengagement of the loops in the stretching operation. The crosshead is connected to the jack so as to be capable of pivoted balance-lever movement, two return springs 9 for the jack being arranged to act on the crosshead at opposite sides of the jack to urge the crosshead towards its normal position at right angles to the axis of the jack. The cylinder 1 of the jack, Fig. 2, is,attached at its base to the thrust framework 3 which comprises four rods 32 attached to plates 30, 31 at each end and the ram 2 of the jack is pivoted to the crosshead 5. The crosshead is detachably connected by, the links 20 to the stressing member 10 which is positioned between the rods 32 of the thrust framework. Wires to be strained are connected to the stressing member by wedges'15 engaging tapered grooves in the member. The wires pass through an anchoring block 4 by which they can be locked in position by wedges after straining and the thrust framework is positioned on this block. The links 20 are formed of strip metal-with the ends bent over and welded into loops 22 which engage recesses 11, 12 in the members 5 and 10. In a modification, Fig. 4, which is intended to strain wires around a cylindrical structure the thrust member is replaced by a wheeled carriage having a member 29 at its end opposite to the jack in which one end of each wire is gripped by wedges, the wires then pass through grooves in a plate 38 and round the cylindrical structure, through a second set of grooves in the plate 38 and then to. a stressing member 40 arranged underneath the carriage and attached by links 20 to a crosshead 5 on a jack ram as in the first embodiment. With this arrangement the strain is applied equally to both ends of each wire, the carriage moving on its wheels to permit this. The two ends of each wire are arranged one over the other in the member 38 and alternate pairs pass through the grooves in opposite directions to prevent torsion on the member 38. The member 38 also has a threaded bolt which bears on the structure while the initial pair of wires are being strained to prevent the member tilting. The carriage has four screwed spindles 45 by which it is initially positioned after which the wheels 42 which are slidably mounted are lowered into position and the spindles disengaged. Specification 690,981 is referred to.

Title: Improvements in or relating to bearing surfaces of light metals or alloys
IPC: F16C33/14
Filed: 1944-05-22
Abstract: In a method of coating a light metal or alloy bearing surface with a thin film of lead the surface is first cleaned and degreased and then an aqueous solution of a lead salt is applied and a film of lead deposited on the surface by chemical substitution.  As a preliminary step after degreasing traces of a halide of the metal to be coated may first be formed on the surface.  In an example an aluminium article is degreased, any parts not to be coated are painted with a quick drying varnish, immersed for 30 seconds in a solution of 7 to 15 per cent. by volume of hydrochloric acid in methyl alcohol, allowed to drain and finally immersed in an aqueous solution of 8 to 26 grams per litre of lead acetate for 15 to 30 seconds which time gives a coating of lead of .001 in. in thickness.  The protective varnish is removed and the article dried in air at room temperature or by heating to 100 DEG  C. for 2 hours.  The liquids may also be applied by brushing, sponging, or spraying.
