Title: Improvements in bon bon coating machines
IPC: A23G3/24
Filed: 1923-02-28
Abstract: 215,489. Heilman, J. C. Feb. 28, 1923. Coating confectioners' goods. - A bon-bon coating-machine of the dipping type comprises an oscillatory member having core-holding baskets which are momentarily positioned beneath a feeding-device, a vertically movable trough which raises the coating-material from the tank and applies the coating, means for swinging the baskets away from the coating-posi. tion, shaking them to remove surplus coating-material and inverting them above a receiving-table where a vertically moving rake disengages the bon-bons from the baskets. The feeding-device comprises a receptacle A<1> having pockets a<1> in which the cores are placed by hand, a pivoted bottom plate a<2> retaining them temporarily over the baskets b carried by the oscillating arms b<2>, b<3>. The receptacle A is lowered, after charging, by cams a<8>, the bottom plate being displaced during the movement by the rods a<3>, a<4>, allowing the confections to fall into the baskets b after which the receptacle A rises. The arms b<2>, b' are operated by cams and mutilated gearing from the charging position to the positions shown in dotted lines in Fig. 1. A short rest at each position allows the coating-tank C to rise and submerge the cones, excess coating to be shaken off by a spring returned vibratory member D actuated by projections g<7> on the gear wheel g<3>, and a reversal of the baskets, to deposit the goods on a table F<1>, by a pinion e engaging with a rack E. The pinion e has a radial arm e<10> which is positioned, on the return movement, between guides x<1>, x<2> whereby the core baskets b are correctly positioned. A cam-operated, vertically moving rake e<1> ensures the removal of the goods from the inverted baskets b. The cones are prevented from floating in the dipping trough by wires a<15>, a<16> which are lowered on to the cones by camactuated rods a<6>.

Abstract: 368,508. Drilling. CONSOLIDATED PNEUMATIC TOOL CO., Ltd., 170, Piccadilly, and SCOTT, G., 20, Eswyn Road, Tooting, both in London. Feb. 25, 1931, No. 5910. [Class 83 (iii).] In a fluid-pressure feed-motion for a pneumatic or electric portable drill, the feed is effected by a pneumatic piston, pressure being applied to both sides of the piston for a slow starting feed and to the larger side only for the working feed. A cylinder a is attached to the casing of the drill by a screw thread b and receives a piston c whose rod d carries a centre for engaging a fixed abutment. Air is supplied to the cylinder through a valve p and pipes g, h, the valve having two sets of ports l, m'and the cover j being provided with three indicated positions for starting feed, full feed and stop. In the first position air is admitted to both sides of the piston to produce a slow feed until the drill has reached its full working speed, whereupon a quarter-turn of the valve connects the side c<1> of the piston to exhaust and maintains pressure on the side c<2> to give the full working feed. A further quarter-turn of the valve connects both sides of the piston to exhaust, and a spring may be provided in the cylinder to effect the return. The feed may be used with drills of small diameter by maintaining the valve in the starting position. A particular example of piston and rod dimensions and pressures is given in the Specification.

Title: Improvements relating to synchronising and speed control devices
Inventor: ELLIOTT ALBERT GEORGE
IPC: H02P5/46
Filed: 1951-03-13
Abstract: 707,063. Automatic speed control systems. ROTOL, Ltd. June 10, 1952 [March 13, 1951], No. 6084/51. Addition to 516,613. Class 38 (4) The arrangement of the parent Specification is applied to the synchronization of e.g. pairs of reaction-propulsion gas turbine engines of an aircraft, each eng'ne driving an alternator supplying stator windings of a single dynamo-electric machine so as to produce two rotating magnetic fields tending to rotate the rotor, which has a closed winding, at a speed corresponding to the difference between the speeds of the two rotating fields, fuel supply to one of the engines being controlled by the rotor to restore synchronism. In Fig. 2 a swash-plate type fuel pump 14 for the controlled engine (not shown) is driven by that engine at 15 and pumps fuel from a tank 18 and conduit 19 to the engine through conduit 26 the rotor of the dynamo-electric machine (not shown) controlling a valve 60 feeding a variable quantity of fuel back to tank 18 or to the suction side of the pump. For a given atmospheric pressure, deviations of fuel pump delivery pressure from a predetermined value are detected by a piston 43 acting on a lever 35 pivoted on a diaphragm 36 to control a bleed valve 34 associated with a servomotor 28 which corrects fuel delivery pressure by adjustment of swash plate 23. A bellows 45 responsive to atmospheric pressure acts on lever 35 to cause fuel pump delivery pressure to decrease with atmospheric pressure. In this arrangement valve 60 is in series with a manual throttle 27 but in a modification, Fig. 3 (not shown), it is in parallel with the manual throttle and provides a finer control. Instead of the rotor of the dynamo-electric machine adjusting valve 60 it may alternatively act on the adjustable abutment 42 of a spring 41 acting on lever 35 to effect speed correction.
