Abstract: 575,921. Drawing profiled tubes. DEWEY, C. L. Aug. 28, 1944, No. 16309. [Classes 83 (iii) and 83 (iv)] A tube for use in making furniture, lamp standards or fixtures, bicycle or airplane frames, &c., is shaped by moving it relatively through a die opening formed by dies adjustable radially to the tube to apply pressure in closely-spaced lines transverse to the axis of the tube. A carriage 50, Fig. 1, is mounted on ways 48, 49 and has four radially-movable slides 71, each pressed towards a fixed templet 28, 33, 40 or 45 by springs 74 and carrying a die 78, Fig. 2, with its face grooved to form blades 80 which are transverse to the tube and arranged to pass between the blades of the two adjacent dies. With the carriage 50 in position A, Fig. 4, and the dies 78 fully withdrawn, a tube T, preferably tapered or shaped as described in Specification 519,500, is fixed between a spring-pressed centre pin 89 and chuck jaws 81 operated by a hydraulic piston 85. The carriage 50 is then moved to the right by a screw 64, gearing 93 and motor 94, the dies being moved by the templets 28 to produce a square section from 6 to 7, a flat rectangular section from 8 to 10, and a square section from 10 to 11. When the carriage 50 reaches the position B, the tube can be withdrawn and bent as required. By using four dies with their acting faces shaped cross-sections such as shown in Figs. 17 or 18 can be produced or with six dies sections such as in Figs. 13 to 16. In a modification, the part,50 is fixed and the tube and templets move longitudinally.

Title: Improvements in the manufacture of pottery ware
IPC: C04B33/02
Filed: 1932-06-10
Abstract: Dense refractory pottery ware is made by using a eutectic mixture (approximately equal parts) of clay and talcum, or a mixture having the clay or talcum slightly in excess, as a sintering agent or flux for the main raw materials, e.g. refractory clays, refractory oxides, silicates, nitrides, or carbides.  The main materials may contain clay but not felspar, quartz or talc.  The clay-talcum mixture constitutes from 10 to 50 per cent of the body mixture.  The talcum and clay may be added separately or first sintered or melted together.  The fluxing action of the clay-talcum eutectic may be modified by additions such as manganese dioxide, rutile, marble, beryl, pyrolusite, bone ash, fluorspar, &c. up to 10 per cent of the mixture. Examples are: (1) 65 parts of alumina and 35 parts of a eutectic mixture of clay and talcum; (2) 20 parts of magnesite, 30 parts of zirconium silicate, and 50 parts of eutectic mixture; (3) 75 parts of zirconium oxide, 20 parts of eutectic mixture, and 5 parts of Lothian or Dorset clay.  Other examples are given.

Title: Improvements in or relating to circular rib-knitting machines
IPC: D04B9/10
Filed: 1931-06-09
Abstract: 380,092. Circular rib knitting- machines. BENTLEY, P. A., GODDARD, J. H., (trading as BENTLEY ENGINEERING CO.), MANGER, C. F., and WAINWRIGHT, C. H., Komet Works, New Bridge Street, Leicester. June 9, 1931, No. 16809. Addition to 337,058, [Class 74 (ii), Knitting &c.]. [Class 74 (ii).] The machine described in the parent Specification is modified to permit cutting and trapping of the auxiliary yarn at the end of each fractional splicing course to be suspended at will. When the yarn is to be cut &c. the yarn feeder 26 in swinging on its pivot to the feeding position causes the yarn from the trapper to lie across the front of the needles since the first needle to receive yarn uses up most of the piece freed by the opening of the trapper only a short end is left. The trapper is closed again when the last needle to receive yarn has arrived at a position just behind it. When the yarn is to be floated, the trapper is left open, so that the yarn runs freely through it until the floating is to be suspended. A pivoted finger 290 is then manually or automatically moved so that a screw 292 carried by it releases a plate 293, Fig. 2 (not shown), and allows the cutter and trapper to be brought again under the influence of a cam 260 on the running shaft. The screw 292 is held by spring action against the plate, which is secured to a lever 264 forming part of the cutter &c. operating device. When the plate is in its lowest position, a ledge on it engages below the screw 292 and is thus prevented from rising until again released. The use of the special short-ribbed sinkers described in the parent Specification is avoided by advancing somewhat the timing of the cutter &c. and retarding somewhat the timing of the sinkers. Specifications 15008/00, [Class 74, Lace-making &c.], 24290/12, and 171,483, [both in Class 74 (ii), Knitting &c.], are referred to.

Filed: 1967-04-12
Abstract: 1,176,016. Automatic load control. GENERAL ELECTRIC CO. April 12, 1967 April 12, 1966], No. 16817/67. Addition to 1, 088, 879. Heading G3R. A turbine 2 drives a generator 50 whose load is sensed by an A. C. watt transducer 53 having a D.C. output signal. The rate of change of load is detected by differentiating the D.C. signal in unit 54, a load reference source 55 and a load rate reference source 57 being provided. A selector 59 disconnects an acceleration reference source 17 and differentiator 16 from summer 18, a selector 60 adding load reference to speed reference signals, and actual load to actual speed signals. The signals from units 54, 57, are compared in the integrating summer 18 whose error is applied to low-value gate 20. The total reference signal from sources 55, 13, and the actual speed/ load signals from sensors 3, 53, are compared in summer 14 and the integrated speed/load error signal is applied to the gate 20. Either input to the gate can serve as a valve-positioning signal through componenets 21, 22, but only the signal representing the smallest valve opening can control at one time. After the turbine has reached full speed, the load error is greater than the rate error so that the latter signal is gated to set the valve 1. Thereafter the load error decreases and becomes the gated signal to assume control of the valve. Speed and acceleration control is afforded, as described in Specification 1, 088, 879.

Title: An acoustic electric filter system
Inventor: VRIES ADRIAN JOHN DE
IPC: H03H9/145
Filed: 1969-03-31
Abstract: 1,260,525. Electromechanical filters; frequency discriminators. ZENITH RADIO CORP. 31 March, 1969, No. 16856/69. Headings H3A and H3U. A filter suitable for embodying in integrated circuitry comprises, Fig. 1, a substrate 14 of piezoelectric material having on its surface transducers 13, 15 constructed as interleaved comb-type electrode arrays. The arrays 13, 15 are formed by vacuum depositing gold, the distance between the centres of two consecutive strips in each array being ¢ the wavelength or an integral multiple of ¢ the wavelength, of the signal that is to be propagated. The electric field set up by the transducer 13 coupled to the signal source 10 produces an acoustic surface wave which is detected by the transducer 15 and applied to a load 18. The source 10 may be the tunable front end of a TV receiver and the load 18 may be three stages of the receiver subsequent to the IF selector. Inductor coils 12, 16 form tuned circuits with the capacitance of the arrays 13, 15. In another embodiment, Fig. 3, the two arrays having terminals A, B and C, D, respectively, are circular. To reduce the 3 db loss associated with each transducer, the transmitted surface wave may be reflected from an end surface of the substrate 14 of Fig. 1 by bevelling one end of the substrate (Fig. 4, not shown). In another method of reducing the 3 db loss, Fig. 5, additional passive arrays 27, 28 are provided on the substrate body 30. In another embodiment (not shown) the surface of the substrate is coated with photoconductive material and the interleaved comb type arrays are formed by projecting light rays through transparencies having the desired pattern. The pattern may be readily changed by using different transparencies to produce a tuning feature. Another readily tuned embodiment, Fig. 6, comprises transducers 47, 50 printed on a carrier 48 of low acoustic impedance placed under a polarized piezoelectric bar 49. Since the stripes of the electrode arrays 47, 50 are not perpendicular to the bar 49, lateral movement of the bar permits tuning. An FM discriminator embodying the filter comprises, Fig. 7, a transducer 31 coupled to source 10 and output transducers 32, 33 coupled through diodes 36, 37 to a load 40. The resonant frequencies of transducers 32, 33 are respectively below and above the resonant frequency of transducer 31. In another embodiment of FM discriminator (Fig. 8, not shown) there is a single input transducer and single output transducer. Fig. 10 shows in block diagram form the IF channel of a colour TV receiver employing elements SWIF No.1... SWIF No. 4 each of which is as described with reference to Fig. 1 or Fig. 7.

In an ultrasonic pick-up tube comprising a cathode 4, and an electron-pervious electrode 9 facing one surface of a vibration-sensitive target 2, the target surface is stabilized at a potential which is negative relative to both the cathode and the pervious electrode, and a signal output is derived from electrons which are projected from cathode 4 towards the target surface, and which are returned from the surface through electrode 9, preferably into an electron multiplier 10. During operation, potentials of - 10, + 2 and + 300 volts relative to cathode 4 may be applied to conductive coating 3 on piezo-electric target 2, electrode 9 and wall anode 7, respectively. The target may be stabilized initially, and during frame or line return periods by electron beam scanning with cathode 4 a few volts negative, or by use of an auxiliary flood source of electrons. The target 2 may be a continuous crystal, e.g. of quartz, supported at its inner surface by a metal grid which may constitute pervious electrode 9. Alternatively, the target may comprise elementary crystals arranged in the apertures of a metal grid.
