IPC: A47L23/05
Filed: 1957-05-22
Abstract: 799,656. Shoe polishers. OHNESORGE, W. May 22, 1957, No. 16259/57. Class 138(1). A device for the automatic application of shoe cream to rotating brushes b with a cylinder c receiving the shoe cream and a piston d displaceable by means of a spring f, is characterized in that as closure for the cylinder mouth a rotatable roller e is arranged which is in contact both with the shoe cream in the cylinder and the brush b. Filling the cylinder is facilitated by the nozzle g which is covered by gap h. The brush and roller may rotate in the same or opposite directions, in the latter case their peripheral speeds being different. Fig. 2 shows the roller attached to the cylinder by means of the bars n and the combination pivots on the lever k about the bearing m. The cable o passing around rollers r and attached to springs f serves to ensure that the tension of the springs will only be applied to the piston when the roller is in the working position. The pulley wheel t may drive the roller e by means of the belt s.

Title: Improved golf practice device
IPC: A63B63/00
Filed: 1936-06-11
Abstract: 467,944. Golf-practising appliances. BUDD, W. E. June 11, 1936, No. 16383. [Class 132 (ii)] In a golf-practising device including a target mounted for reciprocation as a unit in the line of flight of the ball, the target is spring mounted to enable it to recoil under the impact of a ball and to return thereafter, and a direction indicator is provided comprising a number of indicating elements arranged across the target. A golf ball 82 is driven from a tee 76 towards a concave target 8 carried by rails 11 movable longitudinally of a carriage 5. Upon the impact of the ball with the target, the latter moves to the left against the action of a spring 17. This movement is measured by an instrument 30 that is operated by an abutment on a cross-head 14 connecting the rails 11 at their right-hand ends. The instrument, Fig. 3, comprises a pointer movable relatively to a chart graduated to indicate the distance the ball would have travelled had it been unimpeded. The pointer is retained in set position, against the action of a return spring by a manually releasable brake 33. The carriage 5 is mounted for universal movement relative to a base 1, its position after the ball has struck the concave surface of the target serving to indicate the line of flight of the ball. The direction of the ball is also indicated by a series of fingers 20 at the top of the target, each finger being associated with a spring rod 18 that, upon the impact of the ball therewith, releases the finger for movement to indicating position. The interior of the target is covered with sponge rubber 26 to deaden the impact of the ball. Rebound of the ball from the target is prevented by a pair of shutters 35 each carried by a shaft 36 and normally retained by a trigger device, against the action of springs, in the ineffective position shown in full lines. The movement of the target consequent upon the impact of the ball therewith trips the trigger device and permits the rotation of the shutters to the operative position shown in broken lines. A handle 60 is provided to reset the shutters and indicator fingers, and simultaneously remove a cover 67 from an aperture 69 to allow the ball to escape from the target. Before a stroke is made, the target is positioned centrally by the engagement of a lever 80 with a block 84 on a rearward extension 85 of a vertically pivoted part 2 of the carriage. However, upon the counterclockwise rocking of the tee during the stroke, the lever 80 is raised to free the block 84 and permit the carriage to be positioned by the impact of the ball with the target. The ball may be tethered by a short cord 86 to a guide ball 87 slidably mounted between a pair of spring guide bars 88, the outer ends of which are flared to faciltate the escape of the guide ball when the golf ball is struck. The guide bars are connected through a shaft 89 and forked arms 90 to the extension 85 of the carriage 5 and, when the golf ball is struck off the true line, swing the target towards the line of flight of the ball.

Abstract: 683,468. Shuttle stop motion. CROMPTON & KNOWLES LOOM WORKS. June 22, 1949 [March 12, 1949], No. 16610/49. Classes 142(i) and 142(iii) A loom is stopped if the shuttle fails to pass a point on the slay at the correct time by a circuit including two switches in parallel, one being normally closed and the other normally open. The normally closed switch is momentarily opened during every pick by a cam; the normally open switch is closed by a relay in the circuit of a gasfilled electronic valve triggered by the shuttle passing over a coil on the slay as described in Specification 683,518. When the shuttle is operating correctly, the circuit remains uninterrupted, but if the shuttle passes the coil too late, the circuit is broken to stop the driving motor of the loom. In a modification, Figs. 9 and 10, two levers 112, 120 are pivoted at 113, the lever 112 being rocked by a cam 111 on the crankshaft 17; the lever 120 is coupled to a cylinder 123 which operates a hydraulic brake 124 on the crankshaft. The two levers are normally coupled together by a plunger 125 but, when the electronic valve is triggered, a solenoid 128 withdraws the plunger to prevent application of the brake.

A number of fixed contacts 2 on an insulating ring 1 are arranged to be engaged consecutively by a roller 6 on an arm 7 which is centrally pivoted on a collar 8 on a rotatable shaft 9 and urged by a tension spring 11 to produce the contact pressure. The contacts 2 are inclined to the radius so that as the roller 6 traverses their surface, the spring 11 is increasingly tensioned until the roller clears the contact and snaps on to the next. In Fig. 1 there are six sets of contacts of which 2, 2<SP>1</SP>, 2<SP>11</SP> have their contacts all connected together by a metal band 5 in a channel 12 having a cover 13 through which the appropriate terminal S, S<SP>1</SP>, S<SP>11</SP> projects for connection to the three phases of the supply. Each roller 6 bridges a pair of contacts of adjacent sets to connect its phase in turn to contacts of sets 3, 31, 3<SP>11</SP>. The ring 1 need not be insulating, in which case the last-named contacts must be insulated from the others. The shaft 9 is driven through reduction gearing by a constant-speed motor 10 bolted to the gearing casing 16.

Abstract: A method of purifying mixtures of soap and fatty acyl aminomethane sulphonate, in which the sulphonate is suitably derived from mixed C12-C18 fatty acids of which not more than 50% are unsaturated, preferably palm kernel fatty acyl aminomethane sulphonate, consists in boiling the mixture with additional water together, if necessary, with additional salt, so that the upper layer which forms on settling consists essentially of a purified mixture of soap and sulphonate, and the lower layer consists of an aqueous solution containing the bulk of the inorganic salts.  Fatty amides may be present in the composition in amounts either (a) so that when the weight ratio of sulphonate to soap is not greater than 1.5, the amide comprises not more than 12% by weight of the sulphonate, or (b) so that when the weight ratio of sulphonate to soap is not greater than 3:7, the amide comprises not more than a third by weight of the sulphonate. Rosin soaps may also be present, and the final purified mixture generally contains less than 2% salt.  The aqueous layer containing the inorganic salts, is suitable when separated for re-use in a further salting-out treatment.  According to the Provisional Specification, a similar purification procedure may be applied to compositions containing, in addition to soap, alkyl sulphates, fatty monoglyceride sulphates, fatty alkane sulphonates, fatty acyl oxyalkane sulphonates, alkylaryl sulphonates, fatty alkyl phosphates, fatty acyl aminoalkane carboxylates, and other fatty acyl aminoalkane sulphonates.
