Title: Improvements in hydraulic pumps and motors
IPC: F01B3/00
Filed: 1951-10-22
Abstract: 707,254. Reciprocating pumps. BEACHAM HYDRAULIC CO., Ltd., and BEACHAM, T. E. Oct. 15, 1952 [Oct. 22, 1951; Nov. 14, 1951], Nos. 24539/51 and 26680/51. Class 102 (1). [Also in Group XXIX] In a hydraulic motor or pump in which a swash plate 3 mounted on a shaft 1 is driven by or drives pistons 4 reciprocating in cylinders 6 parallel to the axis of rotation of the shaft each cylinder 6 has a separate distributing slide valve 9 associated therewith arranged radially with respect to the shaft and reciprocated by a common eccentric 10 rotatable with the shaft. The cylinders 6 are formed by bores in blocks 20, also bored for the piston valves 9, and located in a carrier 21 clamped between casing parts 17 and 30 by bolts 33 which also act to hold the valve chest portions of the blocks 20 between the carrier 21 and an end cover disc 32. The blocks 20 are aligned and prevented from rotation by studs 55 in the casing 21 having projections 56 fitting into holes between angled surfaces 57 of adjacent blocks. Alternatively, the blocks may be all in one integral piece. The piston valve bore in each block 20 has three annular enlargements 12, 13 and 14, the middle one 13 being in permanent communication with cylinder 6 and the other two 12, 14 being respectively in communication with a liquid supply inlet port 7 and an exhaust port 8 in the end cover 32 by passages 34, 35 and 37, 38 respectively therein and bores 36, 39 respectively in each block 20. Reciprocation of the valve 9 causes its associated cylinder 6 to be respectively placed in communication with the inlet port 7 during the outstroke of the piston 4 and the exhaust port 8 during the instroke of the piston when the machine acts as an hydraulic motor and vice versa when it acts as a pump; in the latter case the pistons 6 are preferably provided with return springs. The valve 9 is moved radially outwards by an eccentric ring 24 mounted on the eccentric 10 and returned by springs 11 acting on a washer 44 mounted on the outer end of the valve. In a modification springs 11 are dispensed with and the valve is positively actuated in both directions by being pivotally secured at its inner end to an eccentric ring. Specification 646,371 is referred to.

Title: Improvements in or relating to electric starters for internal combustion engines
IPC: F02N15/06
Filed: 1937-09-09
Abstract: 488,335. Turning-gear. BOSCH AKT.- GES., R. Sept. 9, 1937, No. 24549. Convention date, Sept. 11, 1936. [Class 7 (v)] In an electric starter in which a pinion d or like coupling member is axially displaceable on the starter shaft a by a lever n and connected to the shaft through a free-wheel clutch f and a threaded sleeve g, a part c of the free-wheel clutch forms a supporting sleeve for the shaft a and is mounted in a bearing k on the casing of the starter. This arrangement protects the starting motor against the penetration of oil from the casing of an engine in which the fly-wheel rotates in oil. As shown, the lever n, which serves also to actuate the starter switch v, engages a divided collar m on the sleeve g, springs t, u being interposed between the parts of the collar and stops r, s on the sleeve, and the movement of either part of the collar being limited by a snap ring q on the sleeve. The latter engages a thread i on the shaft a, so that the axial displacement of the pinion into engagement with the engine gear s is completed by screw action.

Abstract: 615,041. Manure distributers. LLOYD, T. G., and WHITMORE, G. Aug. 17, 1946, No. 24556. Class 6 (i)] [Also in Groups XXX and XXXII] Relates to farm carts which can be used for distributing manure, fertilizers, seeds and the like, and consists in a tip cart having a discharge aperture at the rear and rotary distributing mechanism mounted adjacent thereto, the driving gear member for the rotary mechanism being normally out of mesh but automatically meshing with a gear on one of the ground wheels when the cart is tipped. In the form shown the cart is tipped by a crank 17 acting on screw 14 through gearing. Pinion 44, which is normally out of mesh, then automatically meshes with gear wheel 9 mounted on ground wheel 6. As the cart moves the shafts 31, 31a are driven, in opposite directions, by meshed wheels 43, 43a, through pinion 44. Saw tooth edged discs 32,32a are fixed on the shafts 31, 31a and on rotation cooperate with clearing plates 27, 27a to stir and cut up the manure so that it falls through the distributing way 30.
Patent GB-987063-A (GB)
Title: A method of producing a mixture adapted to serve as a layer for pavement or floor and for similar processes
IPC: C04B20/06
Filed: 1961-07-06
Abstract: Compositions for making layers for floors and pavements and the like are obtained by mixing at least one expanded mineral substance with a water emulsion of pit coal tar pitch and/or of asphalt, and/or of bitumen.  Expanded mineral substances are defined as light weight mineral products obtained by heating certain rocks containing dissolved water so that the material undergoes a substantial increase in volume and becomes porous. The specific gravity of expanded minerals is about 0.2 gm./c.c. compared with 3.0 gm./c.c. for the raw materials from which they are made. Specified expanded minerals are exfoliated mica and expanded obsidian.  The mixture may contain cement which takes up water and hardens the surface of the finished layer.  3-25% of cement, by volume of the total mass, may be used. When a tar pitch emulsion is used it may be of an advantage to add a mineral emulsifier so that after the layer hardens an appreciable elasticity of the binding agent is obtained. Mineral gravel may be present as an additive. Examples are provided of suitable mixtures from which pavements or floors are prepared by compacting layers of 1/2 -2 inches thick.  In a thick layer the lower part may contain the materials in a different proportion from that of the upper part.

Abstract: 208,219. White & Co., Ltd., J. S., and Forster, A. Sept. 13, 1922. Cylinders receiving liquid fuel.-The starting- and working-fuel sprayers of a semi-Diesel engine are mounted in a single plug. and are controlled by a valve or valves connected to a single control member so arranged that only one sprayer is in use at once. The sprayers may use the same or different fuels, and may be arranged to project the fuel in different directions. In Fig. 4 the double beat valve M serves to select the sprayer required, and fuel is injected axially by the working sprayer C', and diagonally on to a suitable hot-spot by the starting sprayer B. The main charge of fuel is delivered through tangential or helical grooves.
