Patent GB-145453-A (GB)
Title: New or improved method of cutting and profiling conical or bevel toothed wheels
IPC: B23F5/20
Filed: 1920-06-18
Abstract: 145,453. Delamare, R. L. J. Aug. 28, 1917, [Convention date]. Void [Published under Sect. 91 of the Act]. Gear-cutting. - Bevel-gears are generated by a straight-sided cutting- tool or milling-cutter operating simultaneously on both sides of the tool by giving the tool a tangential displacement and the blank a rolling motion, the tool being reciprocated along a path such that the imaginary apex 11, 11<1> of the tool moves in a straight line towards the apex 1 of the generating-cone. The latter intersects the large and small ends of the bevel at the points 6', 7<1>, and 6, 7 respectively. The method may be applied to cutting bevels by means of formed cutters and is also stated to be applicable to the cutting of helical or skew bevels.

Title: Improvements in or relating to cathode ray tube apparatus
IPC: H03K4/28
Filed: 1935-06-08
Abstract: 457,929. Valve generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and BANKS, G. B., Electra House, Victoria Embankment, London. June 8, 1935, No. 16724. [Classes 40 (iii) and 40 (v)] The deflecting coils 2, Fig. 1, of a cathode ray tube are short-circuited during the 'flyback ' periods to eliminate effects due to the self-inductance of the coils and so allow an oscillatory voltage of saw-tooth wave form to be applied to them. A neon tube 1 is connected in shunt with the coils so as to discharge during the fly-back periods. The neon tube may be replaced by a grid-controlled tube 10, Fig. 2, so that the breakdown voltage of the tube may be adjusted by varying the grid bias. Alternatively, the synchronizing impulses may be applied to the grid to cause the tube to discharge.

IPC: G05D16/16
Filed: 1918-10-15
Abstract: 127,180. Dexter, M. Oct. 15, 1918. Pressure-regulating valves.-A diaphragm or float actuated pressure-regulator has the normal action modified by pneumatic pressure admitted to the back of the diaphragm and controlled by a variable head of liquid. The double-beat valve 5 is normally actuated to maintain a uniform pressure by outlet pressure admitted through a port 9 to act on a diaphragm 7 loaded by a weight 10. A pipe connexion 11 to the inlet side of the regulator leads to the chamber 8 at the back of the diaphragm, and also through a flexible connexion 13 to a pipe 14 having a downwardly-turned end dipping into mercury contained in a cup 17 adjustably supported by a bracket 38. To vary the dip of the pipe and thus control the initial head of liquid, the pipe 14 is mounted on a counterbalanced arm 15, pivoted at 18, and provided with a roller 21 adapted to rest on a cardboard cam 24 rotated by the timing-mechanism 30 of an automatic pressure-recorder 26. The cardboard disk is provided with radial and circumferential lines to facilitate laying-out a cam to suit any desired conditions. The outflow from the pipe 14 is collected in a receiver 32 fitted with a discharge pipe 35. In a modification, the lever 15 is actuated by the main diaphragm 7.

Preferably the plug (Fig. 3) comprises a body member 40 slidable on a mandrel 30 to define a first position wherein a resilient sealing ring 41 carried by the body engages the first tube wall and radially extending keeper pins 46 housed within the body are supported by a shoulder 32 of the mandrel to keep clips 47 in engagement with annular recesses 48 in the tube wall so effecting locking of the plug relative thereto; and a second position wherein the mandrel is displaced to the right (Fig. 3) relative to the body by pressurized fluid introduced via orifice 55 so urging apart body 40 and a thrust ring 50 carried by the mandrel to relax resilient ring 41 and release clips 47 which are urged radially inwardly by biasing springs (not shown) after pins 53 holding a retaining disc 52 are sheared to allow shoulder 32 of the mandrel to move clear of the keeper pins. Alternative to the single sealing ring 41, a pair of axially spaced sealing rings may be provided between which an annular expansible test ring is provided, which test ring when fed with pressurized fluid compresses the seals to test their effectiveness. Preferably respective pipe ends are provided with a ball portion 14 and socket portion 22 (Fig. 2), the socket being provided with a plurality of radially movable slips 25 which are hydraulically actuable to engage the rearward side of the ball portion and effect a fluid tight coupling between the pipe members.

Abstract: 419,388. Valve accessories. HARTLEY, E., 3, Dartmouth Avenue, Newcastleunder-Lyme. June 14, 1933, No. 16926. [Class 135.] A sluice valve is pressed on its seat by wedges 18 and a spindle 13 is secured to the valve member and is threaded at 15 and engages a socket 16 on the valve operating handle 17. To release the valve member from its wedges the handle 17 is rotated and the socket 16 bears against the frame 12. The remainder of the lift is obtained by a direct pull in the handle 17. The amount of opening may be determined by providing several pins 19 which pass through slots 20 and the handle 17 may then be turned so that the pins rest on the surface of the sleeve 21. Alternatively the rod 17 may be extended and threaded in bosses on the valve member and provided with a collar to engage the frame 12. In a further modification instead of the collar the rod is extended past the lower boss in the valve and engages a lug on the valve casing. The mechanism may be applied to pivoted disc valves.

Abstract: 561,594. Thermionic valves. STANDARD TELEPHONES & CABLES, Ltd. Dec. 1, 1942, No. 17053. Convention date, March 3, 1942. [Class 39 (i)] In a multistrand filamentary cathode comprising a number of hairpin-shaped filaments each supported by a hook 62 and having its ends connected to individual rods of groups 14 and 42, the rods 14 are provided with coding means, in order that, despite their greater length their expansion will be the same as that of rods 42. The rods 14 pass through seals in the wall of the tube to connections with a polyphase source of electric power. The rods 42 are connected to a plate 30 which forms the neutral point of the star connection of the filaments to the power supply. The rods 14 pass through plate 30 and a further plate 29 through apertures sufficiently wide to be insulating. Plates 29 and 30 are spaced by rods 26 and plate 29 is mounted on rods 26a which are sealed through the envelope in a similar manner to rods 14. To strengthen the construction these two groups of rods are connected by sealing them through a glass ring 41. Fins 72 on rods 14 form the cooling means which by equalising the expansion of rods 14 and 42 prevents sagging of the heating element.

Abstract: 1400106 Suction cleaners GOBLIN (BVC) Ltd 5 April 1974 [11 April 1973] 17466/73 Heading A4F [Also in Division B1] A suction cleaner, particularly for removing both solids and liquids from surfaces, comprises a motor-fan unit 5 mounted on a receptacle 1 into which it draws picked up material, e.g. via a nozzle and hose coupled to an inlet 2, and a filter  diaphragm 10 spaced from but extending across the admission inlet 6 of the unit 5, and deflectable due to the pressure drop across it which occurs during operation of the cleaner due to partial clogging of the filter diaphragm, and/or by engagement by a member moved in response to the liquid level in the receptacle 1, to cause a sealing pad 15, supported between the filter 10 and the inlet 6, to close the latter, thereby halting the pick-up of material. In the illustrated embodiment the pad 15 is carried by a spring 14 which is bowed upwardly through a dead centre position when acted upon by the deflected filter 10. When liquid is collected in the receptacle 1 a float 20 assists deflection of the filter 10, which is protected against abrasion by a nylon mesh 13, which also assists in dislodging material adhering to the filter 10. In an alternative embodiment the filter 10 is moved against the action of a coil spring 39 Fig. 2 (not shown) to close the inlet 6 by the pad 15, the movement of the filter 10 being assisted, when liquid is collected, by a cranked arm (34) acted upon by a float (41).
