Insoles, machines for. - In a machine for making composite insoles of the type shown in Fig. 7, a die 10, Figs. 1 and 2, is adjustably supported on a cross-head 15 carried by plungers 16 adapted to be reciprocated in guides 20 through link connexions 31, 30 from cranks 29 on a shaft 22, and operates in conjunction with a second die 11 secured by a flange 35 to a carrier 36, which is provided with sleeves 37 surrounding the guides 20; the carriage 36 is reciprocated by link and crank connexions 43, 42, 41, 40 from a shaft 38 geared to the shaft 22. These dies serve to mould the inner member 1, Fig. 7, of the insole, and co-operate with a pair of spring-pressed folding-blades 47 and a bed-plate 9 to mould the outer member 2. The blades 47, Figs. 2 and 3, are slidingly carried on the under side of a carriage 48, which is adapted to be reciprocated yieldingly through a cross-head 52, operated from an eccentric 56 on the shaft 38, and springs 53 surrounding the reduced lower ends of post 49 carried by the carriage 48. The folding-blades 47 are actuated by arms 62 carried by rock-shafts 61 having secured to them arms 64 carrying rollers adapted to be engaged by pivoted links 66, 76, which are connected by cross links 75 and operated through an arm 71 from a cam 74 on the shaft 22. The timing of the machine is such that the die 10 is first moved into the die 11 to mould the angle 4, Fig. 7, on the inner member 1, and then the two dies are moved through the carriage 48 and the folding-blades to superpose the member 1 on the member 2 and to cause the margin of the latter member to be moulded to form its upstanding flange 6. The folding-blades are then moved inwards to grip the flange 6, after which the carriage 48 is moved downwards relatively to the die 11 to cause the blades to fold the portion of the flange 6 adjacent to the bed-plate 9 to form the feather edge 5. The die 11 is then withdrawn, and the folding-blades are given a further inward movement to compress the upstanding flanges 6, 4 against the side of the die 10. As the various parts of the machine are returned to their original positions the finished insole is ejected from the machine by a sliding- plate 81 actuated through links 83, 84 from a cam 86 on the shaft 22. Specification 114, 285, [Class 17 (ii), Boots &c. Construction of], is referred to.

Filed: 1974-04-25
Abstract: 1504136 Fuel injection pumps; starting fuel injection engines CAV Ltd 3 April 1975 [25 April 1974] 18037/74 Headings F1A and F1B In a radial cylinder rotary distributer fuel injection pump wherein the pumping plungers 20 are moved inwardly by respective rollers 29 cooperating with an angularly adjustable internal cam ring 30, the outward strokes of the plungers are determined by the abutment between the adjacent ends of the rollers 29 and a plurality of pivotable links 57 disposed to one side of the cam 30. During normal operation of an engine supplied by the pump the angular position of an annular stop member 60 is such that internal lobes 61 thereon maintain the links 57 in their inward positions. In these positions the links 57 and a fixed ring 52 on the other side of the cam ring 30 limit the outward movement of the plungers 20 and thus the normal maximum amount of fuel delivered. To provide excess fuel for starting the annular stop member 60 is moved angularly to allow outward pivoting of the links 57. This adjustment of the stop member 60 is effected by moving a plate 64 having a toothed tongue 63 engaging teeth on the outer periphery of the member 60. The plate 64 is guided by a squared bolt 66 passing through an elongated slot 65 therein and movement is imparted thereto by an elongated member 49 guided to move perpendicularly to the plate 64 by a slot 73 therein which receives the bolt 66. By rotating a stop control 46 an eccentric 47 thereon co-operates with a recess 48 in the elongated member 49 to move the latter, this movement causing movement of the plate 64 by the cooperation between an inclined surface 71 on the member 49 and a pin 70 fixed to the plate 64. A spring 67 urges the plate 64 to the normal position in which an upturned portion 69 abuts an externally adjustable screw stop 68. Once moved to the excess fuel position the plate 64 is latched by a leaf spring 75 which springs into a position behind an extension 76 on the plate 64. When the engine reaches a predetermined speed the output from a feed pump 17 causes angular adjustment of the cam ring 30 to retard the injection timing and cause a pin 77 to lift the leaf-spring 75 away from its latching position. To stop the engine the stop control 46 is displaced so that an end 50 of the lever 49 closes a throttle 26 controlling the feed flow into the pump. In a similar manner the throttle 26 is moved towards its closed position if the stop control is operated during normal operation.

Abstract: 946,929. Transistor switching circuits. EPSCO Inc. May 23, 1960 [May 27, 1959], No. 18174/60. Heading H3T. In a voltage comparator which assumes one state when an input voltage from a sweep generator 19 is positive with respect to a reference voltage from a source 21 and another state when it is negative with respect thereto, the generator 19 and source 21 are connected to respective bases of transistors 1, 2, having their emitter electrodes connected together and to a constant current generator constituted by a transistor 6 and their collector electrodes connected to respective bases of transistors 26, 27 connected to function as a trigger circuit. Transistor 1 is normally cut off but when the negative-going sweep voltage brings the base of transistor 1 negative with respect to the base of transistor 2, the constant current flowing in transistor 2 transfers to transistor 1, thus switching transistor 26 off and transistor 27 on, this action being accelerated by the positive feedback provided through capacitor 40 from the collector of transistor 27 to the base of transistor 26.
