Title: Improved drive units for looms
IPC: D03D51/00
Filed: 1968-12-03
Abstract: 1,203,860. Clutch-brake combinations. GEOG FISCHER AG. BRUGG. 3 Dec., 1968 [4 Dec., 1967], No. 57423/68. Headings F2L and F2U. A clutch-brake combination has a rigid driven disc 12 axially shiftable to selectively frictionally engage a driving flywheel 16 or a stationary brake ring 17. The disc 12 is connected to an axially fixed driven shaft 7 both by way of a hub 11 fast with an axially slidable pin 10 having a pin-and-slot connection 8 with the shaft 7 and by way of a torque transmitting spring means 19, which may be a diaphragm spring or spring spokes, and which is clamped to the disc 12 between rings 18, 20 and is secured to the shaft 7 by a clamping ring 22. The spring means 19 may be of steel or of a plastics material. The disc 12 is connected to the hub 11 by screws 15 and rubber discs which function as oscillation dampers and also compensate for slight obliquity of the disc 12 relative to the flywheel or the brake ring. The friction disc 12 is shiftable axially by yoke arms 2 having pins 5 engaging a bush 4 which is fast axially with the pin 10. The yoke arms 2 are pivotally connected to a support 25 by pins 3, the support being biased by compression springs 24 (which are provided for regulating and adjusting the clutching pressure) and the yoke arms being pivoted anti-clockwise about the pins 3 by a braking spring 28. Normally the spring 28 causes the friction disc to engage the brake ring 17. On actuating the yoke (by mechanical, pneumatic or electric means not disclosed) the yoke arms pivot about the pins 3 to engage a clutch until the pressure of the springs 24 is overcome, whereupon the support 25 is displaced to release a feeler causing a device (not shown) to retain the yoke in its clutching position.

Abstract: 1362018 Pneumatic conveyers INTERNATIONAL BUSINESS MACHINES CORP 13 Dec 1971 [22 Jan 1971] 57702/71 Heading B8A [Also in Division F1] Articles, e.g. semi-conductor chips 10 to be pneumatically conveyed along a tube 12 are alternately subjected to pulses of pressurized air and pulses of suction. A tube 22 aligned with the tube 12 is bifurcated to form tube 24, 26 with inlets 30, 32 adjacent to a rotary wheel 35. Two further tubes 50, 56 in alignment with respective inlets 30, 32 are respectively connected to a vacuum pump 48 and a pressure pump 54. The wheel 35, driven by a motor 38, has a plurality of equal spaced aperatures 42 arranged on a common pitch circle diameter whereby when the tube 50 is in communication with tube 24 through one of the aperatures 42 the connection between the tube 56 and the tube 26 is blocked and vice versa thereby producing the desired pulses with the rotation of the wheel. By altering the magnitude of the pressure and/or vacuum, the speed of rotation of the wheel and the size of the apertures therein, the speed and direction of the chips 10 can be altered. The tubes 50, 24 are mounted on a yoke (70) Fig. 2 (not shown), pivotable about the rotational axis of the wheel 35 to adjust the timing between the application of the pulses.

Abstract: 1346119 Cyclone separator ENVIROTECH CORP 29 Dec 1971 [30 Dec 1970] 60402/71 Heading B2P  A cyclone, e.g. for removing dust from a gas, has an approximately tangential fluid inlet conduit 4 which is shaped to generate a flow velocity gradient in the fluid, normal to the direction of flow, such that where the conduit opens into the interior of the cyclone the flow velocity increases across the flow as a function of, and preferably in proportion to, increasing radial distance from the axis of the cyclone. The inlet conduit 4, initially rectangular and of increasing cross-sectional depth in the direction of fluid flow, merges into a flow guide 5 which in turn merges into the cyclone chamber. The outer sidewall 7 of the conduit and guide is initially planar up to the radial plane C from which it curves smoothly inwards to merge with the cyclone body along a line diametrically opposite the line 10 along which the inner sidewall 6 merges with the said body. The top wall 8 is planar and integral with the top of the cyclone body. The bottom wall 9 consists of two sections A and B. Section A is planar and triangular and slopes downwards towards the plane C giving the conduit increasing cross-sectional depth. Section B is initially planar sloping to form obtuse included angles with section A and the outer sidewall 7. At the plane C section B curves round joining the body of the cyclone to the outer sidewall of the flow guide, its shape being a partial conic section.

Abstract: 682,468. Spray-carburetters. DAIMLER-BENZ AKT.-GES. May 9, 1950 [May 9, 1949], No. 11572/50. Class 7 (iii). In a carburetter having an auxiliary jet brought into operation by the accelerator linkage actuating the throttle valve, an independent resilient stop in the path of the accelerator pedal, or a part operated thereby, provides an increase of resistance to indicate when the auxiliary jet is brought into operation. Movement of an accelerator pedal m, Fig. 1, operating a throttle valve c through linkage k, from m‹ to m<SP>1</SP>, opens a cock h to supply fuel to the main nozzle e. Further movement from m<SP>1</SP> to m<SP>2</SP> in order to open a cock g to supply fuel to an auxiliary nozzle d is resisted by a spring- loaded abutment n. In Fig. 2 the increase in load on the linkage k is produced by a cam s on the throttle valve spindle having a cam rise s<SP>3</SP> which lifts a lever t against a spring u when the cock g is about to open, the additional load on the linkage remaining constant or even decreasing after the rise s' is passed. The cam may alternatively be provided on the accelerator pedal spindle.
