Title: Improvements in or relating to the bonding of a sole to a welt of a welted shoe by use of the heating effect of a high frequency electric field
IPC: A43D25/06
Filed: 1947-06-27
Abstract: 636,690. Soles, attaching. BRITISH UNITED SHOE MACHINERY CO., Ltd. June 27, 1947, No. 17021. Convention date, June 28, 1946. [Classes 17 (i) and 17 (ii)] In a machine for bonding together a sole and a welt progressively along the welt by the heating effect of a high frequency electric field means are provided for intermittently switching on the high frequency energy only when the work is gripped between the electrodes and for pressing and feeding the work step by step by work-engaging members one of which embodies an electrode. In an example, a shoe welt and sole are fed step by step by electrodes 2, 4, shaped to grip the work which is held, on the return stroke of the electrodes by members 8, 9. The electrode 2 derives an up and down movement from a cam 13 rotated on a shaft 10 the oscillatory movement being transmitted by levers 22, 23, 231, 25 to a collar 29 slidable on a rod 39 and then by a sleeve 32 acting through a spring 30 abutting the extension 38 of the rod 39. The electrode 2 derives a transverse movement from an eccentric 59 on the shaft 10 acting on a yoke 62 the unwanted vertical motion being taken up by the yoke 62 sliding relative to the rod 39. The electrode 4 is pivoted at 68 and is positively connected by a pin to the yoke 62. The presser foot 8 is vertically reciprocated alternately with the electrode 2 by a lever 72 pivoted at 73 to the frame 5 which receives its movement from a pin 74 engaging a slot 75 in the yoke 62. A microswitch 49 is operated through a plunger 50 by a plate 51 attached to a threaded extension of the rod 39 and moving vertically with the electrode 2 to switch on and off the high frequency energy. Adjustment of the nuts 45, 46 or 35, 36 allows the pressure, between the electrodes at which the high frequency supply is switched on to be adjusted. In a modification, the work is fed step by step by the presser members while the electrodes grip and activate the work between steps. Specifications 538,405, 555,054, [Group VIII], 594,993 and 599,298, [Group VIII], are referred to.

Title: Filtering method and apparatus
Filed: 1958-05-29
Abstract: 858,609. Filters. PFAUDLER PERMUTIT Inc. May 29, 1958 [June 13, 1957], No. 17148/58. Class 46. During normal filtration incoming liquid is at level IL in pipe 33, and at slightly lower levels in pipes 40 and 62. Filtrate discharging from pipe 37, and liquid from the last rinsing step, are at level OL. On clogging of the filter bed 19, levels OL remain fixed but levels IL rise until liquid in pipe 62 reaches Y-fitting 61, whereupon liquid flows down leg 63 into sump 46, bringing ejector 60 into operation to withdraw air from bend 44 of backwash pipe 40 along pipe 65. The resulting partial vacuum in bend 44 raises the liquid level in portion 43 until it rises above pipe 71, whereupon liquid passes down pipe 71. This flow entrains air in pipe 45 and discharges it into sump 46, the level in 43 being thus raised further. When liquid finally passes over bend 44 it is deflected at 70, more air is entrained and discharged into the sump, and finally a siphon is established in pipe 40. Thereupon liquid is sucked from above bed 19 past baffle 41 by pipe 40 and is continually replaced by liquid from storage space 17 passing down tubes 18 and upwards through the bed to backwash it. The siphon is broken by air getting into the lower end of vent pipe 57 and reaching the bend 44. Incoming water now passes down through the bed, rinsing it, and rises up tubes 18 and pipe 36 until level OL is regained, whereupon filtrate flow through 37 resumes, and the rinsing water now stored in 17 is available for the next automatically-initiated backwash.

Title: Improvements in and relating to wired broadcasting systems
Inventor: QUINTON KENNETH CHARLES
IPC: H04N7/10
Filed: 1969-04-02
Abstract: 1,234,884. Distributing music &c. COMMUNICATIONS PATENTS Ltd. 2 April, 1969, No. 17219/69. Heading H4R. In a wired broadcasting system pertaining to two colour television transmissions, there is applied to each of two respective conductive networks a modulated carrier wave brightness information component and a modulated carrier wave colour information component, the frequencies of the carrier waves differing from each other by a frequency of approximately (N + ¥)P, where N is any integer and P is the line scanning frequency. Further, the carrier wave of the brightness information component which pertains to one of the transmissions has a frequency which differs from the frequency of the carrier wave of the brightness information component which pertains to the other transmission by where M is any odd integer. In a practical arrangement the carrier waves of the two brightness information components are (378P + 17À5) Hertz and (383À5P - 7À5) Hertz. Beats which arise due to unavoidable non-linearities in the conductive network and of stray signal coupling from one conductive network to the other take the form of a relatively unobtrusive dot pattern.
Patent GB-123942-A (GB)
Title: An Improved Cut-out Gear for Steam Turbines.
IPC: F01D21/18
Filed: 1918-10-22
Abstract: 123,942. Scotts' Shipbuilding & Engineering Co., and Anderson, J. P. Oct. 22, 1918. Regulating.-Relates to an emergency valve for turbines which automatically shuts off the steam supply in the event of the failure of the forcedlubrication system, and which can also be operated by hand and by governor. The emergency valve b cannot open under pressure of steam entering at the point a<1> until the pressures at both sides of the piston c on the valve stem are equalized, this being quickly done by opening a pin valve e in a by-pass d. A hand-wheel f regulates the extent to which the valve b may open by adjusting a sleeve f<1> against a shoulder b<2> on the valve spindle. A handle b<2> serves for hand-manipulation of the valve b. For automatically closing the valve b, the space c<1> above the piston c is connected by a pipe and a valve h to a pipe w leading to the hot-well tank, the unbalanced pressure on the lower side of the piston c thereupon closing the valve b. The valve h is secured to a heavy ram k supported by oil from the forcedlubrication system, or from the gravity tank n, admitted under the ram by a pipe l<1>. In the event of the oil pressure falling below a predetermined limit, the ram k falls and moves the valve h so as to connect the pipes w, j, thereby closing the emergency valve b. The closure may also be effected (a) by moving a cock r by a handlever s so as to connect the pipe l<1> with a drain pipe m<1>, and (b) by the action of the high or low pressure turbine governors q, q<1> tripping detents v, v<1> and allowing valves t, t<1> to fall and shut off the pressure oil. Instead of the heavy ram k, a light piston may be employed, pressed down by a spring or balance weights.

Title: Improvements in and relating to valves
IPC: F16K15/10
Filed: 1943-10-21
Abstract: 576,449. Valves. BROWETT LINDLEY, Ltd., (formerly BROWETT LINDLEY (1931), Ltd., J.), and HUTTON, J. Oct. 21, 1943, No. 17365. [Claas 135] A check valve, suitable for use in air compressors and shown as an inlet valve, comprises four ported members, a valve seat 1, and valve, cushion, and guard plates. 2, 3, 4, respectively, and the opening movement of the valve plate 2 is damped first by contact with the cushion plate 3, then by the resilient loading springs 14 of the latter plate, and finally by the valve and cushion plates coming into contact with the guard plate. The valve seat and the guard plate are held together by a bolt 6 and nut 9 with a washer 10, and the two are spaced apart to permit movement of the plates 2, 3 by a spacing washer 11. The valve plate is pressed on to the seat by springs 13. Stops 15 carried by the seat limit the movement of the cushion plate towards the seat, and positioning studs 16 facilitate assembly of the valve. The valve and cushion plates are interchangeable. In a modification, applied to a delivery valve, the plates 2, 3 carry spring tongues which are secured to the washer 11 and serve to position the plates. Specifications 550,403 and 576,466 are referred to.

Title: Method of producing single crystals particularly of semiconductor material
IPC: C30B13/00
Filed: 1962-05-07
Abstract: 958,852. Zone-melting. C. ZEISS-STIFTUNG, [trading as C. ZEISS [firm of]]. May 7, 1962 [May 9, 1961], No. 17384/62. Heading B1S A single crystal is formed from a seed and adjacent deposited material by the passage of a molten zone through the material from the seed using a deflectable beam of charged particles in a vacuum. The material may be deposited by condensation or sputtering. The size of the deposited crystallites is preferably smaller than the thickness of the molten zone. The temperature gradient on the growth side is preferably greater than that on the supply side. Material deposited as a wafer on to a base may be preheated, e.g. in a tempering furnace, and after the formation of a single crystal, the base may be dissolved off. The whole of the material may be converted into a single crystal by the use of a linear image which traverses the material or a raster image. A wafer of desired size and shape may be subesquently cut out by the use of a beam of greater intensity which vaporizes material in its path, Fig. 2. A portion only of the material may be converted into a single crystal of desired shape by appropriate tracking of the beam or the use of a raster beam of variable intensity, Fig. 5. Similarly a single crystal which is only supported by the seed (the latter being attached to a base at right angles to the resulting crystal structure) may be formed, Fig. 6. The seed may be cut from the single crystal and used again. As shown in Fig. 1, material 15 deposited on a base 14 carried by a movable table 30 is recrystallized by means of a deflectable beam 11 which passes from a cathode I through an earthed cathode 3, a deflection system 6, an adjustable diaphragm 8, an earthed tube 12, an electromagnetic focusing lens 13, and a deflection system 17. The operation is followed by means of illuminating system 20, reflecting prisms 21 and 22, axially movable focusing lens 23, reflecting mirror 26 and observation system 27.

Title: Improvements relating to the deposition of dust or the like from an atmosphere in which it is suspended
IPC: B01D47/06
Filed: 1929-06-06
Abstract: 336,201. Woodall-Duckham (1920), Ltd., and Duckham, A. M. June 6,1929. Air, washing.-Deposition of dust suspended in a gaseous current, e.g. a current of air which has been passed through a bed of coal mixed with shale &c. for stratification and removal of impurities, is facilitated by adding a gas or vapour, e.g. steam or a liquid spray, and so altering the relative densities of gas and dust and in some cases wetting the dust and increasing its cohesion. The stream of added fluid is introduced in the opposite direction to that of the dusty gas which is repeatedly circulated through the depositing chamber. Admission of steam &c. may be controlled automatically by a device brought into operation by the admitted fluid, e.g. a hygrometically sensitive hair or thread may operate an electrical or other relay controlling an inlet valve.

Title: Improvements in or relating to glass feeder plunger operating mechanism
IPC: C03B7/086
Filed: 1955-06-16
Abstract: 769.867. Glass manufacture. EMHART MANUFACTURING. CO. June 16, 1955 [Feb. 8, 1955], No. 17417/55. Class 56 The plunger.5 of a glass feeder is raised by a single acting pressure-fluid motor 12, which is under the control of a rotary cam 42, and is lowered by gravity. The cam 42 operates a slide valve 31 through a linkage 41 comprising a bar 36 pivoted at 37 to a nut member 39 adjustable on a rod 40; and a slide holder 46, pivoted on a stationery centre 70 about which it is moved by a cain-follower 52. The holder 46 carries a slide 45 having a roller 47 bearing against the underside of the bar' 36. The free end 35 of the bar 36 raises the valve 31 against the action of. the spring 32. The slide 45 is movable in its holder 46 by rotating a shaft 73 which, through a worm 71 operates rack and pinion means, the displacement of the roller 47 adjusting the amplitude of the valve 31. The fulcrum 37 is adjusted by turning the worm 58, the worm wheel 56 being splined on the shaft 40 and being held against axial movement by the fixed bracket 54. The rise of the piston 8a, and of the plunger 5, occurs when the valve 31 is lifted to connect the pump 26, and pipe 25 to the pipe 16. The plunger 5 is maintained in correct alignment with the discharge hole 3 by a bracket 64 and roller guide 65 67. The bracket 64 is secured to a spring casing 61 which itself is connected to the rod 40 so that the casing 61 and rod 40 rise and fall with the plunger 5 the spring 63 only allowing relative movement of 'the parts 40, 61 when the fluidpressure fails and the heavy plunger assembly falls violently, the spring 63 then acting as a cushion. In the position of the cam 42 shown, the valve 31 is closed and the plunger 5 is in its lowest position. Rotation of the cam lifts the valve 31 and admits fluid-pressure to the motor 12 the consequent rise of the pivot 37 causing the bar 36 to fulcrum on the roller 47, the consequent lowering of the end 35 of the bar 36 allowing the valve 31 to be returned. by the spring 32, to the closed position at the conclusion of the up-stroke of the plunger 5. The roller 52 is now on the highest part of the cam 42 which extends over a considerable " dwell." The roller 52 then drops into the low part 42a of the cam and the valve 31 moves down to connect the motor 12, via the pipes 16, 29 with the reservoir 28. The fall of the plunger 5 is accompanied by a fall of the pivot 37 which restores the valve 31 to the closed position.

Abstract: 865,096. Valve amplifying circuits. TELEFUNKEN G.m.b.H. May 31, 1957 [June 2, 1956], No. 17460/57. Class 40(6) [Also in Group XL(b)] The working point of a screen-grid valve used as an amplifier is stabilised by feeding the screengrid through a resistor from a point whose potential is considerably greater than that of the anode voltage supply. As applied to a video amplifier in a television receiver, the screen-grid is fed via resistor 6, from the boost condenser 7 of the line deflection system. A tapping point on the resistor 6 may be connected to a control electrode of the picture tube, in order to reduce variations in the black level when the gain of the valve or mean picture brightness changes. The screen-grid decoupling condenser 9 may be restricted in value in order to boost higher frequencies: in a modification (Fig. 3, not shown) an additional stage of R.C. smoothing is used and the condenser 9 may then comprise the inherent capacity of the valve and circuit. In the sound channel (Fig. 2, not shown) both the screen-grid voltage for the audio output valve and the anode potential of a preceding triode amplifier are obtained in this manner in order to reduce hum.
