IPC: D01H13/10
Filed: 1921-10-26
Abstract: 191,511. English Electric Co., Ltd., and Darlington, W. E. Oct. 26, 1921. Driving - arrangements. -A speed controlling device for ring spinning frames and the like whereby the tension on the thread is kept approximately constant, is operated from the thread itself or from another thread in which the tension is proportional to the tension in the thread being wound. Resting on the thread 3 being wound is a jockey-pulley 1 attached by an arm 2 to a pivoted and counterweighted contact 7, which is adjustably supported by springs in a casing 13 carried by a bracket on which it can be adjusted. By these two adjustments the required tension may be applied for any particular speed. Should the tension in the thread decrease, the contact 7 moves to the left and touches insulated contacts 19 thus linking up a generator 21 with a solenoid relay 24 through wires 22, 25, Fig. 2, and thence with a motor 36 through wires 35. This motor actuates the change-speed device 41 through reduction gearing 42 and the speed of winding is increased. Should the tension increase, the contact 7 is moved to the right and connects the generator 21 with a solenoid relay 37 and thence with the motor 36 in the reverse direction so that the speed of winding is decreased. The relays are provided with time lag devices so as not to be affected by temporary changes in the tension of the thread.

Title: Improvements in or relating to photographic shutters
IPC: G03B9/26
Filed: 1946-09-25
Abstract: 620,060. Photographic shutters. KODAK; Ltd. Sept. 25, 1946, No. 28603. Convention date, Oct. 12, 1945. [Class 98 (i)] An everset shutter, comprising a pivotally mounted cover blade connected to a trigger and normally held in a position of rest by means of a spring to cover an exposure aperture, and a shutter blade connected to a hair-pin spring adapted to be tensioned and released by the movement of the trigger and cover blade, has means connected by a second hair-pin spring to the cover blade and trigger which, upon depression of the trigger to tension and release said second spring, is actuated by this spring to impart a starting impulse to the shutter blade. As shown, a shutter blade 3 apertured at 6 and a cover blade 14 are pivotally mounted at 4. 15 on opposite sides of a supporting plate 1 having an exposure aperture 2 and an arcuate slot 28 through which passes a pin 7 on the shutter blade, and an L-shaped lever 25, stepped at 27, is pivoted beneath and coaxiatly with the shutter blade. On depressing the trigger 17, which is pin-and-slot connected at 18 to the cover blade and carried in lugs 23 of a bracket 20 attached to the plate 1, against the-action of a spring 24, the cover blade is rotated clockwise to uncover the aperture 2. This movement tensions two hairpin springs 10, 33 which are connected between a pin 13 on the'cover blade and pins 7, 30 on the shutter blade and the lever 25 respectively. Due to the relative dispositions of the two springs and because spring 33 is much stronger than spring 10, the spring 33 commences its driving action first, so that the edge 37 of'the lever 25 drives the pin 7 until the pin 30 engages the adjustable stop 38 and, depending on the position of the adjustable stop 5, may even impart a starting impulse to the pin 7 on the shutter blade. Once the pin 30 engages the stop 38, the shutter blade is driven solely by the weaker spring across the exposure aperture, and finally the pin passes beneath a spring blade 22 secured at 21 to the plate 1 preventing rebound of the shutter blade. On releasing the trigger 17, the spring 24, being stronger than either of the springs 10, 33, drives the cover blade anticlockwise, and when the cover blade pin 13 passes beneath the tip 42 of the spring blade the shutter blade pin 7 is released, allowing the shutter blade to return to its initial position.

Title: Improvements relating to fluid pressure braking apparatus
IPC: G01R19/155
Filed: 1927-10-28
Abstract: 310,551. Westinghouse Brake &. Saxby Signal Co., Ltd., (Chevillot, A.). Oct. 28, 1927. Fluid-pressure.-A controlling or distributing valve is influenced by a constant pressurecontrol chamber supplied from the train pipe, which supply is prevented or materially restricted until the train pipe pressure is stable at its normal running value. In Fig. 1, the constant-pressure chamber 24 serves as a control spring for a graduating release valve 5, and the fluid supply for the chamber 24 from the train pipe 4 through the triple valve 7 is cut off by a valve 27 closed by the pressure in the brake cylinder 3 during brake operation while the train pipe pressure is unstable. On brake release the brake cylinder 3 is exhausted through a cavity in the triple slide valve 9, pipe 11 and a valve 22 in the release valve 5, also the auxiliary reservoir is supplied from the train pipe 4, through the triple valve chamber 4, pipe 13, a re-charging valve 35- and a pipe 16. Too rapid charging of the auxiliary reservoir tends to close the valve 35 and open the valve 22 owing to the differential pressures on diaphragms 19, 20. Too rapid venting of the brake cylinder tends to close the valve 22 and open the valve 35. The chamber 10 is at atmospheric pressure. A modification is shown in which the accelerating bulb of the triple valve constitutes the constant-pressure chamber and is charged with fluid under pressure from the train pipe during brake application through a valve which is closed by the pressure, in the brake cylinder when this has a predetermined value, this valve simultaneously closes a second fluid supply to the auxiliary reservoir which is not controlled by the valve 35. In a further modification, the constantpressure control chamber 61, Fig. 3, is adapted to influence the triple valve piston 52 from which it is out off in brake-release position by a valve member 64 on the piston 52. The chamber 61 is supplied with fluid from the train pipe 53 by means of a groove 55, a conduit 56, a port 57 in a piston valve 58 and a conduit 60. This piston valve is moved against auxiliary reservoir pressure in a chamber 73 and a spring 75 to cut off the supply to the chamber 61, by brake cylinder pressure acting in a chamber 67 on a piston 66. Seats 77, 78, 79 co-operating with valve members 80, 81, 82 prevent leakage past the joints of the valve device. Specification 285,142 is referred to.

Abstract: 1447831 Stencils R F EISENBEISS [trading as ALBERT ROSE] 1 July 1974 [30 June 1973] 29119/74 Headings G2C and G2X A stencilling material e.g. for use in rotary film printing comprises a photo-sensitive coating on an ink-pervious supporting screen through any area of which ink can be applied to a receiving surface following removal of the screen coating in that area, characterized in that the photo-sensitive coating contains a substance which fluoresces in ultraviolet light. The coating suitably contains 0À1 to 1À5 wt per cent of a dye e.g. of the imidazolone type which fluoresces in ultraviolet light, and may be a chromate-sensitized coating. The support may be a cylindrical rotary printing screen. Suitably the composition of the photo-sensitive coating is such that it can be exposed to ultraviolet light and the consequential fluorescent light from the said substance without destroying the photosensitivity of the coating, so that after an overall exposure of such material to U.V. light a printing stencil can be formed by imagewise exposing to actinic light and then developing the stencilling material. Defects in the resulting stencil are revealed as dark spots on exposure to U.V. light and can be sealed with retouching lacquer.
