Title: Fluid Control Valve
Inventor: KAY FRANCIS XAVIER
IPC: B60T15/20
Filed: 1967-01-23
Abstract: 1,153,227. Valves; fluid-pressure brakes. INSTRUMENTS & MOVEMENTS Ltd. 19 Dec., 1967 [23 Jan., 1967], No. 3376/67. Headings F2F and F2V. A pressure responsive valve, for use in a servo-assisted pneumatic braking system, comprises a casing having an inlet 4 and an outlet 12, a passage 7 between the inlet and outlet, a valve seat 18 around the passage for engagement by a closure member 16, a piston-rod 22 containing a bore opening through a pistonhead 24, a spring 34 between the piston-head 24 and a piston 25, and means for applying a control signal to the piston 25 to displace it and thus vary the thrust of the spring, the piston 25 having separately movable parts 25A, 25B which interact with one another and with stops, whereby the effective area of the piston is diminished at a predetermined value of the control signal to provide a non-linear relationship between signal and outlet pressure. A bias spring 20 holds the closure member 16 against its seat until a signal pressure applied through a channel 14 displaces the piston 25 to the right to lift the closure member 16 through the spring 34 and piston-rod 22. Fluid from the inlet now flows by way of the passage 7 to the outlet 12 and acts on the piston-head 24 to close the member 16 if the outlet pressure exceeds the required value, the piston-rod 22 being separated from the member to relieve the excess pressure through vents 13. If the outlet pressure is below the required value, the piston-head 24 is moved to the right by the spring 34 to increase the lift of the closure member 16. When the part 25A of the piston 25 reaches the rightward end of its travel, the effective area of the piston is reduced to <SP>1</SP>/ 6  to provide a kink in the input signal-outlet pressure characteristic of the valve. A separate two-part piston 26 enables the valve to be operated by a signal applied through a duct 15.

Title: Improved means for loading coal mine tubs from main road conveyors
IPC: B65G67/00
Filed: 1948-02-06
Abstract: 633,264. Loading coal tubs ; endless-belt conveyers; shoots. BUTTERLEY CO., Ltd., and HOPKINS, E. A. Feb. 6, 1948, No. 3502. [Classes 78 (i) and 78 (iv)] Means for loading coal tubs from main road conveyers in mines comprises an inclined shoot, fed by a conveyer, which is enclosed to contain the dust and has at its delivery end a rotary cutoff plate interconnected by an operating handle with a stop to prevent movement of the tubs down an inclined track beneath the shoot, so that when the tubs are held up, a tub is in position to receive coal from the shoot and the cut-off plate is moved out of the shoot to allow coal to pass into that tub, and when the loaded tub is allowed to travel from beneath the shoot, the cut-off plate prevents discharge of coal from the latter. As shown, coal is fed from a conveyer a to tubs h down a shoot b which is provided with a cut-off plate e, which is moved into or out of a position about its axis g across the shoot to hold up delivery to the tubs by a handle i. This latter through links p, q also operates a spring- controlled stop k which normally holds a tub in position to receive coal from the shoot, but which may be withdrawn to allow the tub to proceed down its inclined track x, the handle i simultaneously moving the plate e across the shoot b. The shoot is provided with one or more water sprays d to keep down dust, an observation window n and a light fitting o for illuminating the interior of the shoot. Spillage aprons m are movable into and out of position by the lever i to prevent coal falling over the sides of the tubs, whilst a scraper (not shown) between the shoot and the internal surface of the plate e where the latter passes into and out of the shoot prevents small coal from passing out under the shoot. A cross ribbed pulley r removes fine particles of coal from the return run of the conveyer a.

Title: Chrominance signal attenuation
Inventor: ILLETSCHKO GERHARD
IPC: H04N9/64
Filed: 1970-01-28
Abstract: 1,244,825. Colour television. FERNSEH G.m.b.H. 28 Jan., 1970 [22 Feb., 1969], No. 4076/70. Heading H4F. To prevent a disturbing pattern being produced by the chrominance signal upon the reproduction of a colour television signal, the chrominance signal in the luminance channel is attenuated by an extent which is reduced with reducing amplitude of the chrominance signal. Preferably the chrominance signal is attenuated to a constant amplitude level e.g 20% of the maximum amplitude, so that in those parts of the picture having low colour saturation where the amplitude of the chrominance signal is less than this constant amplitude no attenuation is effected. Therefore in the weakly saturated parts of the picture the full frequency spectrum of the luminance signal is available and sudden changes of the luminance are faithfully reproduced without overshoot. In a first embodiment, Fig. 1, the colour television signal is fed via a delay device 2 (transit time equalizer) to a colour sub-carrier attenuator 3 whose blocking depth is controlled by a control voltage Us derived from the chrominance signal which is filtered out by band-pass filter 4, and passed via a threshold value device 5 which only passes that component which exceeds a predetermined amplitude to a rectifier 6. Attenuator 3 may comprise a conventional sub-carrier suppressor having a damped blocking circuit tuned to the sub-carrier frequency which is bridged by a controllable variable resistance e.g. in the form of a field effect transistor (Fig. 3, not shown). Devices 5 and 6 may be interchanged. In a second embodiment, Fig. 2, the colour television signal is applied directly and via a subcarrier attenuator 8 which is not controllable and effects a constant attenuation equal to that necessary for the maximum amplitude chrominance signal, to a blender mixer 9, and control voltage Us derived as in Fig. 1 being used to control the proportion of the two input signals appearing at the output. Devices 11 and 12 comprise transit time equalisers.

Title: Improvements in plate bending rolls
IPC: B21D5/14
Filed: 1931-02-10
Abstract: 361,209. Plate - bending rolls. BENNIE, H. O. and ORR, R. W., Clyde Engine Works, Govan, Glasgow. Feb. 10, 1931, No. 4117. [Class 83 (iv).] In a set of rolls for hending a metal plate closely round a forming roller to form a cylinder, the forming roller is associated with a reinforcing beam and with three or more outer rollers which, after the preliminary bending of the plate by the forming roller, are moved up to the forming roller and rotated to complete the bending operation. The plate 4 to be bent is first placed as shown in Fig. 1 and the forming roller 1, supported against deflection by beam 5, is lowered to bend the plate to a U-shape with the bottom of the plate engaging the lowermost roll 3. The side rollers 2, 21 are then moved in the direction of the arrows, Fig. 3, to press the plate more closely round the forming roller while the beam 5 is raised. The outer rollers 2, 2<1>, 3 are then revolved by power applied to one or more of these rollers, first in one direction to roll down one of straight portions of the plate and then in the other direction, Fig. 5, until the cylinder is completely formed. The side rollers are then withdrawn, the forming roller with the work moved upward and the work withdrawn. In a machine embodiment the rollers 2, 2<1>, 3 are supported in bearing blocks, 7, 7<1>, 7<11> respectively, which are movable in guideways in end housings 6. The forming roller is mounted in slotted members 8 connected to the reinforcing beam, which consists of a girder 5<11> secured to a part 5<1> shaped to fit the forming roller. Vertical guides for the reinforcing beam are provided in the end housings. The members 8 are quickly detachable so that one or both may be removed for removing the finished pipe. The rollers 2, 2<1> may be simultaneously adjusted by means of screws working in nuts 10, 10<1> rotated by worm gearing 11, 11<1> from longitudinal shafts 13, 13<1>, which are connected together by a cross shaft 14 and bevel gearing and are driven by an electric motor or other source of power. Similar gearing may be employed for adjusting the lower roller and the upper forming roller. Reversible gearing is also provided for rotating one or more, preferably all, of the rollers 2, 2<1>, 3. Forming rollers of different sizes may be provided and the machine may be used for bending plates to U-shape or for bending partially bent plates into cylindrical shape. The work may be either hot or cold. One or more of the outer rollers 2, 2<1>, 3 may also be reinforced by girders if necessary.
