Title: Improvements in or relating to circuit arrangements for producing a saw-tooth current through a coil
IPC: H03K4/90
Filed: 1959-07-14
Abstract: 923,717. Valve sawtooth current-generating circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. July 14, 1959 [July 17, 1958], No. 24163/59. Class 40 (6). The invention relates to sawtooth currentgenerating circuits of the type comprising an output transformer 4 (Fig. 1) fed from a driver valve 1 and connected to a deflection coil circuit 5 and a diode booster-damper circuit 3, 6. According to the invention, non-linearity of the output waveform due to the resistance of the coil is prevented by connecting a capacitor 7 to the terminal of the diode 3 not connected to the coil and feeding a constant current to the capacitor during the sweep. The voltage across the capacitor accordingly rises during the sweep so that the voltage drop across the coil resistance is offset. When the circuit is operated in such a mode that the diode current remains constant the constant current may be provided from a constant current source 8. In Fig. 3, however, the diode current is allowed to change during the sweep. Accordingly, the current is fed to the capacitor 7 through the secondary of a transformer having a high leakage inductance the primary being connected to a valve 13 controlled by the diode current flowing in resistor 9 so as to reduce the current flowing through the transformer secondary as the diode current changes. In Fig. 4 current is fed to the linearising capacitor 7 through an inductance 15 and the current through the capacitance produces a voltage across a resistance 25 which controls the discharge rate of a capacitor 18 in the sawtooth voltage generator providing the sawtooth wave input to valve 1.

Abstract: 1515922 Apparatus for teeming molten metal OFFICINE MECCANICHE DANIELI & C SpA 4 June 1975 24186/75 Heading F4B Apparatus for teeming molten metal along the same flow axis into a mould comprises a vessel 14 with a discharge nozzle 18 and a rotary valve mechanism 12, the moving parts of which rotate about an axis AA to start and stop the teeming of metal. The invention can be used with water cooled moulds for the vertical continuous casting process. The valve 12 comprises a fixed base assembly 20 with a circular refractory disc 33, a valve support assembly 22 secured by spring subassemblies 60 and set screws 65 to the base assembly, and a rotary closure assembly 24 with a disc shaped refractory plate 40 rotatably mounted in the valve support assembly 22 and driven by a mechanism 26. The spring assemblies 60 spring load the plate 40 against the disc 33 in fluid tight engagement. The plate 40 has an inclined bore 45 which communicates with and is aligned with the bore 32 of the disc 33 when the closure assembly 24 is in the fully open position. The lower end of the bore 45 permanently communicates with the bore 52 of a collector nozzle 50 that is attached to and moves with the closure assembly 24. The bore 52 is on the axis of A-A which forms the central axis of the rotary valve 12, so that when the closure assembly 24 is rotated the nozzle 50 rotates with it around the axis A-A. For operating the rotary discharge valve 12 from the closed position, the drive mechanism 26 is actuated to rotate the closure plate 40 over the surface of the stationary disc 33 so that the top end of the bore 45 is brought into communication with the bore 32 of the stationary disc 33. A heat shield 91 may be fitted to the support assembly 22 to protect the valve mechanism.

Title: Filter with vibration of screen
IPC: B01D29/00
Filed: 1972-05-24
Abstract: 1391710 Filters DOVER CORP 24 May 1972 [27 Dec 1971] 24322/72 Heading BID Liquid is filtered by introducing it through inlet 4 into casing 1 wherein the liquid passes inwardly through the side wall of a hollow filter element 23 which is maintained in continuous (or frequent intermittent) agitation by an agitator 31 secured to the filter element, the filtered liquid flowing out of the open upper end of the element to chamber 51 and outlet 53. The filter element, which may comprise stainless steel wires, is connected to collar 22 by a tubular connector 24 of flexible material, such as heavy rubber. The agitator 31, which is actuated by compressed air supplied through hose 42, comprises a ball 38 (Fig. 2) orbiting in an annular chamber 37, the air entering the chamber through opening 33 and leaving through centre opening 32. The exhaust air leaves the filter apparatus through hose 43. The orbiting of the ball causes a lateral movement of the lower end of the filter element and of the hoses 42 and 43; and this effects an agitation of the filter liquid. Also described is a filter apparatus wherein the agitator is secured to the inside of the filter element (Fig. 3, not shown). In this embodiment the filter element is rigidly connected to the casing but the element is resilient itself, e.g. it may be an elongated resilient member coiled in a spiral form with axial irregularities between adjacent coils providing the filtering space thereof. The filter element may comprise a bellows section (Fig. 4, not shown) in order to permit a component of axial motion. The pneumatic agitator may be replaced by an electrical vibrator.

IPC: C03B23/09
Filed: 1962-06-26
Abstract: A method of forming a thickened flange on an end portion of a heavy-walled glass tube comprises the steps of continuously rotating the tube about its axis, heat-softening a terminating end portion of the workpiece, contacting opposing internal and external surfaces of the heat-softened end portion with a pair of shaping rolls while both are being rotated at substantially the same peripheral speed as the respective contacted workpiece surface, moving the shaping rolls relatively towards one another to form the internal and external surfaces of the workpiece end portion, the latter being formed into an exteriorly-projecting thickened flange, and contacting the terminating edge surface of said end portion with a laterally-movable non-rotating shaping member to form a transverse end surface having a greater width than the initial workpiece sidewall thickness. A glass working lathe 10, Fig. 1, includes a tailstock 13 mounted on a carriage 14 slidable on rails 15 and a fixed headstock 12. A chuck 16 is driven by an electric motor 17 through a belt 18 to rotate a tubular glass workpiece 20. The tailstock 13 has a shaft 19 mounted in alignment and driven in synchronism with the chuck 16 through a series of belts and pulleys and a bed plane drive-shaft 21. A burner carriage 30 is slidably mounted on the rails 15 and carries a pair of <PICT:0956198/C1/1> <PICT:0956198/C1/2> burner blocks 32 with nozzles 33 supplied with gas and oxygen through a line 34.  Shaping rolls 44, 45, which are of a carbon-graphite composition, are either both positively driven by gear trains or the roll 44 is driven by friction on contacting the internal surface of the workpiece 20 with the roll 45 is positively driven. In either case the rolls 44, 45 are driven at the same peripheral speeds as the internal and external surfaces, respectively, of the workpiece 20.  The operation of an air cylinder 50 moves a camplate 54 from right to left to the position shown in Fig. 2 freeing cam followers 58, 59 from the influence of cams 56, 57 and allowing first an arm 42 and then an arm 43 to be drawn by springs 60, 62 against stops 61, 63.  The arms 42, 43 which are pivoted at points P carry the rolls 44, 45 which are thus drawn into contact with the workpiece 20 after suitable heating of its free end. The tailstock is then moved from right to left so urging an end forming member 47 into contact with the softened end of the workpiece 20.  The springs 60, 62 may be replaced by air cylinders.
