Title: Improvements in or relating to apparatus for use in playing social games
IPC: A63F3/00
Filed: 1929-09-05
Abstract: 332,802. Walss, W. Jan. 21, 1929, [Convention date]. Board games.-In games in which the board on which characters or men are placed is required to be rotated through an indeterminate distance relatively to the men during the course of the game, the rotatable board 1 is placed underneath a stationary transparent plate 10 on which the men stand. The board 1 carries exchangeable flexible covers 8, carrying the required design and clipped in place by a spring 9, and may be spun by hand or, as shown, by a spring motor 4 wound by a wheel 7 and held by the spherical roller head of an arm 14 engaging notches in a wheel 3 secured to the board. The arm can be withdrawn from the wheel 3 by a push-knob 18 and when released slows the board until finally it engages a notch and stops the board at one of a number of selected points in the arc of rotation. The lid 11 carrying the plate 10 is hinged to enable the covers 8 to be changed, and a drawer 13 to contain characters is provided in the base. Games are described in which the men move substantially radially and in some cases circumferentially on the plate 10, their movements being determined by the part of the design which arrives beneath them when the board has been rotated, in one case a simple subtraction sum also requiring to be solved to determine the extent of the movement.

Abstract: 888,695. Hard fibre spinning machines. MACKIE & SONS Ltd., JAMES. Aug. 11, 1958 [Aug. 27, 1957], No. 26999/57. Class 120(2) A flyer gill spinning machine for hard fibres has a drafting roller common to all flyers and haul pulleys that-draw fibres from the drafting roller through smoothing dies, the relative surface speeds of the drafting roller and haul pulleys being capable of continuous smooth variation by adjustment of the speed of the haul pulleys relative to their rotary carrier. The haul pulleys 20 are mounted on the carrier 21 which is driven through gearing 25, 26, 28, the pulleys themselves being driven through gears 22, 23, spindle 32 and gears 33 and 34 from the output shaft 36 of a variable speed gear-box 37. Adjustment of the ratio of the gear-box 37 may be made by a control handle 39. Rotation of the flyers is effected by a rope drive from the main drive shaft 10 of the machine. Specification 810,654 is referred to.

Abstract: 1,249,812. Semi-conductor devices. FERRANTI Ltd. 13 May, 1970 [29 May, 1969], No. 27138/69. Heading H1K. A transistor 10 formed in a Si wafer of N conductivity material comprises a N conductivity collector 11, a P conductivity base 12 adjacent a major surface 13, and a N conductivity emitter 14 extending to the surface; the base and emitter being formed by diffusion through a Si oxide mask 15. The collector, base, and emitter base junctions comprise depletion layers 16, 17, and the oxide mask also passivates the surface portions of the junctions. Annular and circular apertures 18, 19 for base and emitter contacts are etched through the oxide layer, and a gold collector electrode 20 is provided on opposite face 21. The oxide layer 15 tends to lower the resistivity of the surface of annular portion 22 of the collector, and to diminish the thickness of the surface portions of the collector-base junction depletion layer, but base contact 23 in aperture 18 is connected to a field electrode 24 on the oxide layer overlying the collector portions 22, which is maintained at a potential difference thereto, producing an electric field across the oxide layer and counteracting the reduction in thickness of the depletion layer. This increases the breakdown value of the collector-base junction. The base and emitter contacts 23, 25 in apertures 18, 19 and the field electrode 24 are formed by selectively etching an aluminium layer deposited on the apertured oxide layer 15, and the field electrode 24 is connected to base contact 23 by a narrow aluminium neck or a small diameter wire 26 spanning a minor part of the surface of the depletion layer of PN junction 16, to avoid instability thereof.

Abstract: 599,230. Skips. STENT, J. D. Oct. 22, 1945, No. 27718. [Class 78(iv)] In a skip for use with cranes and the like comprising a box-like body open at the top and bottom and having hinged shutters which in their closed position form the bottom of the skip and which are adapted to open downwardly, a rotatable shaft supported by the box, and chains or cables connected to the shutters which are adapted to wind on the shaft when this is rotated, to close the shutters, a locking member is provided which is manually movable from an operative position in which it is disposed in the path of movement of means positively rotated by the shaft whereby the latter is locked against rotation to retain the shutters in their closed position. In the embodiment shown, the shutters 4 of the skip are closed by chains 8 which wind on drums 9 on a shaft 6 when this is rotated by a hand wheel 12 through gearing 13 in a housing 11 secured to the skip. A pawl 14 normally engages one of the gears of this gearing to prevent a load dropping through the. shutters and is disengaged to allow the shutters to open by a lever (not shown) projecting through the gear box 11. A brake band may be placed around the flange 15 on the wheel 12 to provide additional control of the shutters when opening. The shaft 6 may be protected by a shield running longitudinally of the skip above the shaft. In another embodiment in which the shaft 6 projects beyond one end of the skip and is rotated by a tommy bar on this projecting end, a block is provided on the adjacent end wall of the skip which may be swung to or from a position in which it obstructs an arm of the tommy bar. The shaft 6 may be supported, within the skip so as to be adjacent the floor of the skip, being protected by a shield of inverted V-shaped section.

Title: Apparatus for testing the profile of involute gear teeth
IPC: G01B7/28
Filed: 1973-06-12
Abstract: 1414005 Measuring gear profiles G BOUILLON G TORDION and G TREMBLAY 12 June 1973 27823/73 Heading G1N The profile of an involute gear is measured by detecting the difference between the gear profile and a circular profile to give a first signal, then subtracting from this signal a second signal representing the difference between a perfect involute profile and a circular profile, the result being a signal representing the departure of the gear profile from the perfect involute curve. This is illustrated in Fig. 1 where a measuring head 11 is pivoted about point O on the base circle of the gear; the head would normally follow circular path 12 but is deflected by the gear tooth 10. The head thus produces an electric signal indicative of the amount of deflection, i.e. the first signal above. The pivotal motion is transmitted to a cam 14 via gears 17 and 16, the cam shape being such that a transducer 15 produces the second signal above. These signals are subtracted in adder 13 and plotted at 18 against the pivotal angle measured by transducer 19. If the measured tooth has a correct profile the plot is a straight line. The pitch of the gear can also be checked, using gauge 20. This is set to contact a tooth on the pitch circle when head 11 similarly contacts the preceding tooth. When a further pair of teeth are tested this is repeated, the movement of the gauge 20 representing any change of pitch. The change alters the horizontal position of the display at 18. The apparatus is shown in Fig. 6 applied to testing a part gear 22. The gear and the apparatus stand on a flat surface, on feet 24, 44. The measuring head shown in Fig. 1 as 11 is here shown as 130, while the pitch gauge is shown at 150. These gauges are mounted on arm 30 which pivots about its left hand end, this pivoting being transmitted to cam 98 via gearing 90. The cam contacts transducer 114 to give the second signal above. The pivotal motion is effected by turning micrometer 86. To test another tooth the apparatus is pivoted about axis 46 which is positoned at the centre of the gear. Equations are given for determining the cam profile.
