Title: Improvements in machines for sharpening rotary cutters
IPC: B24B3/00
Filed: 1960-11-30
Abstract: 914,938. Grinding. ROWLEY, A. S. Oct. 27, 1961 [Nov. 30, 1960], No. 41156/60. Addition to 885,434. Class 60. The machine of the parent Specification for sharpening rotary cutters is modified in that the cut applied by the grinding wheel to the teeth is varied or adjusted by forming the spindle given the intermittent movement in two parts, one part of the spindle being driven through pinions from the other part, and loosely mounting on one part a worm wheel operatively connected with the pinions, rotation of the worm wheel giving an angular movement of one part relatively to the other part to impart a movement to the cutter arbor. The spindle intermittently rotating the arbor on which the rotary cutter undergoing grinding is mounted is formed in parts 7, 7<SP>1</SP>, the part 7<SP>1</SP> being journalled in a bush a<SP>1</SP> in the part 7. A pinion a is mounted on or formed integral with the spindle 7. A pinion b is mounted on the spindle 7<SP>1</SP>. The pinions a, b engage a double pinion c, d (rotating as one) carried on a stud d<SP>1</SP> mounted to rotate with a worm wheel 18<SP>1</SP> loosely mounted on spindle 7<SP>1</SP>. The worm wheel 18<SP>1</SP> meshes with a worm 18 mounted on a shaft rotated by a hand wheel corresponding to 21 in the parent Specification. Pinions a, b, c, d may have respectively 36, 32, 20, 16 teeth. Pinions a, b may be separated by a washer d<SP>2</SP>. When the worm wheel 18<SP>1</SP> is stationary (because the hand wheel is not actuated), rotation of spindle 7 effects rotation of spindle 7<SP>1</SP>. When the spindle 7 is stationary (because the indexing mechanism is not actuated) rotation of the worm wheel 18<SP>1</SP> effects fine adjustment of spindle 7<SP>1</SP>.

Abstract: 1,006,028. Route setting. STANDARD TELEPHONES & CABLES Ltd. Oct. 18, 1963 [Oct. 19, 1962], No. 41237/63. Heading B7N In a route setting system of the entranceexit type, each crossover, e.g..that formed by points W1, W2 is provided with four route search relays RS11, RS12, RS21, RS22, corresponding, respectively, to each track a, b, c, d, entering the crossover and a further relay RSC which is energized when a route is set up over the crossover to prevent the setting up of any other conflicting route through the crossover. Assume a route from track a to track d a search signal on line al energizes relay RS11 which at its contact RS111 extends the search to line dl similarly a signal in line d2 picks up relay RS22 which at its contact RS221 extends the search to line a2. On pick-up of these relays, relay RSC is energized via front contacts RS112 and RS222 and back contacts RS123 and RS213 of the de-energized relays RS12 and RS21, and at its contacts RSC1, RSC2, RSC4 and RSC5 prevents pick-up of relays RS12 and RS22 by a subsequent search signal seeking to set a further route through the crossover.

An injection mould for producing plastics containers with rims free of flush comprises a mould section 14 receiving a core pin 12 to provide therebetween a mould cavity 16 into which material is injected from a means 18. When the core pin is moved downwardly to close the cavity, annular sealing surfaces 20, 22 of the parts 14 and 12 engage at a position spaced from a recess 26 in the core pin in which the container rim is formed. The pin is driven downwardly by a rocker arm 38 pivoted anticlockwise by an hydraulic or pneumatic motor 48 against the action of springs 60 and 80, the latter acting between a stationary member 84 and a nut 82 on the pin. Upward movement of the pin by the spring 80 is limited by an adjustable stop pin 84<SP>1</SP> on a yoke 88 pivoted at 90 and forked at 96 to engage the pin 12. The yoke is biased to move in an anti-clockwise direction by a spring 100. The parison thus formed is placed in a blow mould and fluid introduced through passages 116, 118 to finally shape it.

[Also in Division G3] A stacking machine, e.g. for newspapers, of the kind in which articles are stacked on holders 15 carried by an endless conveyer 13 is provided with a control system (Division G3) for automatically controlling the speed of the conveyer to match the number of articles delivered to it so that each stack contains the same number of articles. Newspapers 10 are delivered to the machine by a first conveyer 11 and the stacks removed by another conveyer 18. The holders 15 are mounted on conveyer 13 by a lost motion. assembly and an electromagnetically withdrawable latch 32 is arranged to arrest each holder just before it intercepts the feed of newspapers and to release it as soon as a predetermined number have been stacked on the preceding holder. The conveyer 13 is driven by a motor 21 through a slipping clutch 22 allowing the whole conveyer to stop if the holder is delayed for more than the lost motion allows. The control system (Figs. 3, 4 not shown) adjusts the supply to motor 21 according to the rate at which the newspapers are delivered.

Title: Transistorized voltage regulator
IPC: H02P9/30
Filed: 1959-12-09
Abstract: 883,505. Automatic voltage-control systems. BENDIX CORPORATION. Dec. 9, 1959 [Dec. 29, 1958; Dec. 30, 1958], No. 41924/59. Class 38 (4). In a voltage regulator for an A.C. or a D.C. generator in which the field is intermittently energized through a transistor, a D.C. signal proportional to generator voltage is applied to a measuring bridge together with an A.C. modulating signal so that the output of the bridge keys the transistor on and off, the mark/space ratio depending upon generator voltage error. The field of an A.C. generator 38 is energized from a rectifier 56 through a transistor 27. Alternatively the transistor may control the field of a D.C. exciter for the alternator. The output voltage of the generator is also rectified at 52 and partially smoothed by a capacitor 6 to provide a D.C. component with an approximately saw-toothed ripple. A portion of the D.C. component is dropped across a gas tube 7 and the resultant is applied to one diagonal of a bridge consisting of resistor 9, the two parts of resistor 10 and a Zener diode 8. As the generator voltage increases, so the bridge approaches balance providing an output which is a sawtooth approximation with an average D.C. level inversely proportional to the generator voltage. This output is applied to a transistor amplifier 13, 21 which is designed to be well overdriven by the sawtooth signal so as to produce a square wave output having a mark/space ratio dependent upon the D.C. level of the sawtooth. This square wave switches the transistor 27 in the field circuit. In a modification, Fig. 2 (not shown), a D.C. generator is similarly controlled, the signal applied to the bridge being modulated by an external A.C. source.
