Title: Improvements in or relating to oil-cooled pistons for high-speed internal combustionengines
IPC: F02B3/06
Filed: 1954-06-10
Abstract: 769,919. Pistons. MAYBACH MOTORENBAU GES. June 10, 1954 [June 16, 1953], No. 17140/54. Class 122 (1). An oil-cooled piston for an internal-combustion engine, in which the ratio of the thickness of the crown 2 to its diameter is from 1 : 6 to 1 : 4, comprises piston-rings 6 carried by the crown, and at least two concentric, annular coolant channels 10, 12 in the crown which form part of a spiral and/or labyrinth cooling system into which oil enters through the channel 10, which extends outwards over the top piston-ring at 11, and leaves through the channel 12, the walls of the channels being arched towards an annular contact surface 3 between the channels. Pockets 14, 15, Fig. 1, separated by radial ribs 16, are formed in the body of the piston beneath the channels 10, 12 which are reduced in section by filler members 18, 24 attached to the radial ribs, the filler 18 having radial slots 20, Fig. 3, on its upper surface to produce a turbulent flow of oil entering the channel 10 through a tube 26. The stream divides upon entering the channel and is reunited diametrically-opposite the tube 26 when it passes through passages 27 into the inner channel 10. Diametrically-opposite the passages 27, the stream passes through at least one opening 19, in the filler 18, into the pockets 15 which are connected by an annular channel 17 and open into a collecting chamber 13, 131 through radial passages 28. An opening 29 in the collecting chamber allows the oil to flow into the interior of the piston where it may lubricate the gudgeon-pin, the supply of oil preferably being so adjusted that the oil emerges intermittently from the opening 29, and the crosssection of the passages being so arranged that substantially the same temperature difference exists at all points between the piston crown and oil stream. The detachable crown 2 or body 1 or both and the fillers 18, 24 may be formed of light metals. In a modification, Fig. 4, three annular grooves 10, 31, 32, with co-operating pockets 41, 42, 43, are provided and the oil is fed from the central collecting chamber 37, 37<SP>1</SP> back into the circulating system through ducts 44, 45. The oil may also be fed into the channels 10 at two opposite points. If the oil is conveyed inwardly along a spiral path, this may be alternately reversed in direction as it proceeds inwards. In a further modification, the inner annular channel in the crown may communicate with an annular channel in the body of the piston and the oil pass from the latter channel through a port into the interior of the piston, a central collecting chamber not being provided. The ratio of thickness to diameter for a steel crown is 1: 6 and for a crown of cast-iron 1 : 4.

Abstract: 280,854. Roots Co., P. H. & F. M., (Assignees of Huebotter, H. A.). Nov. 22, 1926, [Convention date]. Movable-abutment type; governing meters.- In a fluid meter comprising a casing having a fluid passage therethrough and metering mechanism such as intermeshing lobed displacement members of the Root's blower type mounted in the fluid passage, means are provided for positively driving the metering mechanism at a speed bearing any desired relation to the normal rate of flow of the fluid, this speed being preferably such that there will be no difference in pressure between the intake and outlet side of the meter, and no inaccuracy in registering due to slippage of the fluid between the lobed members and the casing will occur. In the construction shown the intermeshing lobed displacement members 11 are driven by supplying oil to a gear wheel pump motor formed by their timing gears 13, 14 which fit neatly in a housing 15. The oil is pumped by a motor-driven pump 27 from a reservoir 25 through a casing 35 and a pipe 16 to the housing 15, and is returned to the reservoir through a pipe 17. The rate at which the oil is supplied to the housing 15 is controlled by a valve sleeve 39 having inlets 40 and an outlet 41 communicating with a passage 42 leading to the reservoir 25. The valve sleeve 39 is secured by a bolt 47 between two diaphragms 45, one of which is subjected by means of a pipe connection 49 to the fluid pressure on the delivery side of the meter, and the other by means of a pipe connection 52 to the fluid pressure on the intake side of the meter. The position of the valve sleeve is adjusted so that when the meter is operating at its normal rate the amount of oil returned to the reservoir through the passage 42 is such that the meter will rotate without supplying or abstracting energy to or from the fluid being measured.

Title: Improvements relating to electric ignition apparatus for internal combustion engines
IPC: F02P7/063
Filed: 1940-12-12
Abstract: 545,361. Ignition systems ; electric switches. LUCAS, Ltd., J., WATSON, E. A., and LAIRD, J. A. Dec. 12, 1940, No. 17606. [Class 7 (iv)] [Also in Group XXXVII] In an ignition system in which the primary winding c of a transformer, Fig. 1, is energized through a discharge switch f from a condenser b charged from an A.C. generator a, a discharge switch e between the generator and condenser comprises a pair of contacts m, n normally held together, means responsive to the motion of the engine for separating the contacts, and an angularly movable member g responsive to engine speed for varying the instant of separation ; after. a predetermined engine speed has been reached, the contact-separating means ceases to be effective, the voltage of the generator then being sufficient to prevent the discharge of the condenser through the generator. In one form, Figs. 2 and 3, the switch e is mounted on the member g, which is pivoted at h, movable between stops i, j, and normally held by a spring k against the stop i. The movable contact n on a pivoted or resilient arm o is separated from the fixed contact m by a cam p, on an engine-driven shaft l, acting on a thrust piece r on the arm o. Within the cam p is a freely-rotatable member s having an eccentric pin t engaging a slot u in the member g, and a friction clutch between the cam and the member s comprises shoes w pivoted in the cam and normally held in engagement with the member8 by springs y. The initial position of the member r (in chain lines, Fig. 2) is outside the range of the cam p. Slow rotation of the shaft l causes the parts s, t to rock the member g against the stop j, bringing the member r into the full-line position in which it is actuated periodically by the cam p to separate the contacts m, n. As the speed increases, the grip of the clutch w on the member s decreases, allowing the spring k to move the member g towards the stop i, so that the instant of actuation of the contacts is delayed until actuation ceases. In a modification, the rotary member s is loaded by a spring and carries a snail cam adapted to determine the position of the contacts relatively to the contact-separating cam, one of the contacts being carried by a spring-loaded pivotal arm adapted to co-operate with the snail cam and the other contact being carried by an arm actuated by the contact-separating cam.
