Patent GB-384911-A (GB)
Title: Improvements in or relating to methods of treating the surfaces of golf balls or other rubber articles
IPC: C08J7/046
Filed: 1932-06-04
Abstract: The invention relates to the production of hard surfaces on rubber articles by treatment with a halide of an amphoteric metal dissolved in an organic solvent, as described in the parent Specification.  It consists in controlling the hardness and flexibility of the surface by the selection of solvents of one or more of the following types: (a) inert solvents, such as ethylene dichloride; (b) solvents which form addition products with the halide and thus retard its action, e.g. esters of carboxylic acids and halogen-substituted carboxylic acids, alcohols, ketones, phenols and hydrocarbons; (c) solvents which swell the rubber to a limited extent, such as toluene; (d) substances which accelerate the action of the halide, such as stearic acid.  Numerous members of these four classes are specified. According to a typical example, a golf ball is treated with a solution of 5 parts of the tetrachloride in 12 parts of ethylene dichloride and 6 parts of ethyl acetate, and is subsequently washed with acetone.

Title: Improvements in and relating to the control of a sequence of operations, particularly of electrical washing machines
IPC: D06F39/00
Filed: 1949-06-16
Abstract: 672,933. Time switches. BRITISH THOMSON-HOUSTON CO., Ltd. June 16, 1949. [June 19, 1948] No. 16075/49. Class 38 (v). [Also in Group XXIV and XXXV] A control apparatus, e.g. for washing machines, comprises a sequential control for a series of operations, an interval control, means effective during one of the operations for shifting the drive to the interval control, and means effective at the end of the interval for shifting the drive back to the sequential control, means being provided for positioning the driving motor so as to be in driving engagement with the sequential control alone or the interval control alone. The sequential control comprises a cam drum 14 co-operating with switches 6 ... 8 and driven clockwise by a motor 21 through gearing and a clutch 24. A gear 28 is driven by a pinion 22, which, together with the motor, is bodily movable to disengage gear 28 and engage a gear 29 connected to a pinion 30 through a spring friction clutch 31a. When a wheel 3 is rotated to move the drum to start the sequence of operations, the gear 28 initially is rotated until at the commencement of the "wash" operation, a cam follower 20 falls into a recess 15 in the drum whereby the switch 8 is actuated by spring 41 to close contacts 43, 44 to energize the heater 40 of a bimetal strip 35 which is carried by a fixed bracket 36 and supports the motor 21 and pinion 22. As the winding 40 heats the strip 35, the latter deflects and engages gears 22, 29. A toothed segment 31 engaging pinion 30 is thereby rotated counter-clockwise about a pivot 32 so that a lug 33 thereon engages the actuator 20 of switch 8 which opens. The strip 35 cools down and restores the engagement between gears 22, 28 to redrive the cam drum. The position of segment 31 is pre-adjustable by an arm 4 so as to vary the length of the "wash" period. In a modification, Fig. 6 (not shown), the motor is supported by the armature of an electromagnet which is energized when contacts 43, 44 close, to effect the change-over. Alternatively, the change-over may occur on deenergization of an energized electromagnet which normally holds the gears 22, 28 in engagement. Specification 633,054 is referred to.

Title: Hydraulic power transmission
Inventor: LAMBETH DENNIS ERNEST
IPC: F16H61/42
Filed: 1964-04-18
Abstract: 1,098,456. Hydrostatic transmissions. DOWTY TECHNICAL DEVELOPMENTS Ltd. April 13, 1965 [April 18, 1964], No. 16184/64. Heading F2C. An hydraulic power transmission comprises tilting head pump 4 and motor 2 connected to shafts 3, 1 in fixed relative positions, the two heads pivoting about fixed parallel axes PT, MT and being connected on pivot axes MP, PP by a link 7, the pump head being pivoted to either side of the shown dead centre position in which axes MP, PT, PP lie in a plane, by a servo 11 having limited travel for forward and reverse drive. In the dead centre position of the pump head the motor is in a position of maximum hydraulic capacity and axes MP, PP lie on opposite sides of a plane containing axes MT, PT. The quadrilateral linkage MT-MP, MT-PT, PT-PP and MP-PT ensures that for either direction of movement of the pump head from the centre position, the motor always moves to a position of less displacement which latter movements are small during initial movement of the pump. The servo 11 normally prevents the motor reaching a dead centre position but should it be desired to pass the motor through this position then a second servo acting on the motor is provided. In Fig. 3 (not shown) the shafts 1, 3 are at right angles but the same quadrilateral linkage is used; with shafts 1, 3 parallel in Figs. 4, 5 (not shown), a different linkage is used with the angle between MT-MP and MT-MP obtuse; this angle is also obtuse in Figs. 6, 7 (not shown), wherein shafts 1, 3 are at an acute angle. The link 7 may be a pair of links housing the hydraulic connections between the pump an motor. The pump or motor, Fig. 8 (not shown), has an annular flange on the driving shaft having sockets for ball joints on the ends of pistons slidable in a block rotatably mounted on a head which can pivot relative to the driving flange. In the transmissions the pump has zero displacement in the pump dead centre position giving approximately equal forward and reverse speed ratios but the position of zero displacement can be spaced from the dead centre position so that the forward speed ratio is greater than the reverse speed ratio. Reference has been directed by the Comptroller to Specifications 994,797, 994,794, 979,532 and 978,603.
