Title: Method and apparatus for magnetic reaction testing
IPC: G01N27/90
Filed: 1967-03-22
Abstract: 1,113,006. Eddy current testing. F. W. BELL Inc. March 22, 1967 [April 6, 1966]. No. 13478/67. Heading G1N. In eddy current testing apparatus a component of the resultant field generated by eddy currents induced in a material S, Fig. 1, under test, by an A. C. energized coil 10, see also Fig. 2 (not shown) and by the coil itself, is measured by a Hall effect device 13 at the surface of the component, adjacent the coil 10. As the coil 10 and device 13 are moved over the surface of the specimen, a reduction in the field at one position indicates the presence of a flaw &c. at that position. This apparatus has particular application in the detection of cracks or discontinuities in an electrically conductive machine component, produced by boring holes in it for screws &c. For this, the coil 10 is centred on the screw or hole and is rotated so that the field round the hole is sensed by the device 13, Figs. 3, 4 (not shown). To obtain from the output of the Hall effect device a signal indicative of the local induced field only, a signal representative of the field produced by the coil 10 is subtracted from the output from the device 13 in amplifier 15, whose output is therefore indicative of the induced field.

Abstract: 735,041. Fireproofing. TITAN CO., Inc. May 28, 1952 [May 31, 1951], No. 13604/52. Class 140. A stable solution for fireproofing cellulosic materials is prepared by mixing a carboxylic acid, water and antimony trioxide and adding thereto titanium tetrachloride, the final solution containing 120 to 160 grams per litre of titanium, and for each mol. of titanium 1.0 to 3.0 mols. of acylate, 0.6 to 1.0 mol. of antimony and 1.0 to 3.0 mols. of chloride and for each mol. of antimony an additional 3.0 mols. of chloride. The required chloride concentration may be maintained by the addition of hydrochloric acid prior to the addition of the titanium tetrachloride. Mono-carboxylic acids, especially acetic and formic acids, are preferred. The solution may preferably be at a temperature of between 30‹ to 50‹ C. during the addition of the titanium tetrachloride. In an example, glacial acetic acid, water, hydrochloric acid and commercial antimony oxide are mixed and anhydrous titanium tetrachloride added beneath the surface of the mixture while maintaining the temperature between 30‹ and 50‹ C. The clear solution is used to impregnate cotton twill, the treated cloth being exposed to the atmosphere to cause gelatinisation of the solution and then washed in sodium carbonatesodium metasilicate solution and finally in water.

Title: Improvements in television transmission of pictures
IPC: H04N3/36
Filed: 1940-08-21
Abstract: 543,709. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 31, 1940, No. 13696. Convention date, Aug. 31, 1939. [Class 40 (iii) ] A television transmission system utilizes a cathode-ray pick-up tube in which the electrons of an electron beam scanned over a mosaic of electron-emissive capacity elements approach zero velocity at the point of impact on the mosaic as described in Specifications 542,219 and 530,409 ; the image of a picture-film or the like is projected on the mosaic momentarily during the return-trace period between successive scannings of the mosaic, thus producing integrated blacker than black impulses x, Fig. 3, at frame frequency ; the mosaic thus locally charged in correspondence with the image is then scanned in successive lines, producing the picture signal v, the A.C. axis of the combined signal x, y being at black-level; the impulses x are clipped off at black-level in one or two stages to produce pedestals ; and synchronizing pulses are inserted on these pedestals in the blacker than black direction. In the transmitting circuit shown in Fig. 1, the picture is projected from a film 12 through a rotating disc 36 on the mosaic 11. The projection system may be as described in Specification 431,207 and U.S.A. Specification 2,082,093, and may be maintained in synchronism with the television signal by means of a control circuit 37 as described in Specification 458,161. Synchronizing pulses are generated in a circuit 26, which may be as described in Specification 448,065 or in U.S.A. Specification 2,132,665. This synchronizing generator 26 controls line and frame scanning generators 31, 28, an amplifier 35 for supplying line and frame blanking impulses, and an amplifier 57 for supplying the line and frame synchronizing pulses to the signal to be transmitted. The signal produced by the charging and discharging of the mosaic 11 is passed by means of a resistance 30 and a condenser to an amplifier 45 followed by an amplifier 50 where the signal is clipped, blanked, and mixed with the synchronizing pulses before passing to the transmitting amplifier 55. The clipping may be performed in one or two stages of negatively biased valves. If the switch 56 is opened thereby disconnecting the blanking amplifier 35 from the signal amplifier 50, the synchronizing signals occur on pedestals at black-level. It is preferred, however, to close the switch and arrange for the circuit to produce pedestals at a level slightly blacker than black. Lost D.C. may be reinserted in any known way, for example, by devices such as described in Specifications 422,906 and 434,496.

Abstract: 1498851 Rolling NIPPON STEEL CORP 4 April 1975 [10 April 1974 15 May 1974 (2) 17 Dec 1974] 13888/75 Heading B3M A metal workpiece is pushed into the rolling gap between two work rolls so that the angle subtended at the roll axis by the area of contact between roll and workpiece exceeds the arc tangent of the coefficient of friction between roll and workpiece, the pushing preventing slipping between roll and workpiece and enabling higher thickness reduction to be achieved in a single pass. In Fig. 3, the ram 3 of a hydraulic cylinder 2 pushes a workpiece W through rolls 1, until just before the ram contacts the rolls, whereupon an inner ram 4 completes the pushing operation. In Fig. 5, the pushing force is provided by a linear induction motor 6. In other embodiments, the pushing force is provided by pinch rolls, by an upstream rolling mill driven faster than the rolls 1, or by apparatus which removes the workpiece from a furnace. Successive workpieces may be joined end-to-end, e.g. welded each then pushing its predecessor into the working gap. Permanent joins may be made by this process. Guides such as rolls may be provided to prevent buckling. A billet may be rolled into an H-section by a universal mill, Fig. 21, having driven rolls 24 rolling the flanges and smaller diameter idler rolls 25 rolling the web. As in this figure, tension may be applied by a gripper 26 downstream of the work rolls 23, or alternatively by pinch rolls or a subsequent rolling mill driven faster than rolls 23. In Fig. 16, the amount of reduction in mill 14 and/or its roll surface speed, and the surface speed of upstream and downstream pinch rolls 13, 15 are controlled by a photoelectric device 16 responsive to the width of the rolled product. The method may be applied to roll continuous castings. Various plant lines are described, Figs. 27-32 (not shown) in which a high reduction mill is preceeded by casting or heating and descaling units, and followed by an edger, further reduction mills, a shearer, and/or a coiler.

Abstract: 614,629. Wire and ribbon resistances; resistance coatings and deposits; variable-contact resistances; mounting terminals. INTERNATIONAL RESISTANCE CO. June 4, 1945, No. 14009. Convention date, June 2, 1944. [Classes 37 and 38 (i)] [Also in Group V] A resistor particularly suitable for a radio volume control comprises a resistance element moulded with an insulating resinous composition to form a base with the element bonded thereto and exposed on one of its surfaces. In the volume control of Figs. 1 and 2, a unitary base assembly 10 comprises an insulating base 15 moulded integrally with a resistance element 11, central bushing 14, central and side terminals 16 and 17, 18 respectively. These parts are shown, Fig. 4, in pre-moulded form, wherein base 15 corresponds to two sheets 27, 28 of incompletely cured resin-impregnated fibrous material. Bushing 14 has an annular flange 14c and an extending sleeve 14d with a knurled part on both sides of an annular groove 14e. A resistance coating 11a is baked on the element 11 at 200  C. and may be compensated to nullify the slight loss in resistance occurring in the moulding operation which carried out at 150 to 160 C. causes sheets 27, 28 to merge into a plastic which fills groove 14e and produces a base 15 with bushing 14 on one side and element 11 on the other with its conductively coated ends 11b and 11c in contact with the ends of terminals 17, 18 which are embedded on either side of a similarly embedded central terminal 16. The volume control of Fig. 1 and 2 includes an operating shaft 12 inserted in the bushing 14 and having secured to its inner end an armature 13 with brushes 13a, 13b bent downwardly to engage the element 11. A coil connector 24 supported at one end by the armature 13 connects the central terminal 16 to the bushes 13a, 13b. A plate 25 fitted over flange 14c and base 15 is fixed by bending over projecting tags 23a of an outer casing 23. In a modification, Figs. 9-10 (not shown), the base assembly 10 includes a metal plate preferably of copper, which in the pre-moulding assembly is inserted between sheets 27, 28 and has spaced radial extensions which are bent over the base 15 in contact with the plate 25 which therefore acts to dissipate heat and prevent hot spots in the base 15.

Abstract: 184,592. Howard, L. C. B. May 20, 1921. Combustion - product plant.-A power plant comprises a cylinder in which is reciprocated a hollow piston, in which the compression, ignition, and combustion of an explosive mixture take place and from which the products of combustion pass tu a turbine or other power unit. In the form shown, the hollow piston 5 in the cylinder 1 worls over a fixed piston 31 and is reciprocated bv means of a piston-rod 7 and a crosshead 10 connected to an eccentric 15 on a shaft 16 driven by the turbine 17. The cylinder is provided with an air inlet 50 and a fuel-sprayer 44, each fitted with a non-return valve. On the down-stroke of the piston 5, air is drawn into space above the piston and on the following strokes it passes through a passage 39 in the piston and through non-return valves 41, 34 to a combustion chamber 37. Fuel enters the chamber 37 from the sprayer 43 through a passage 47 in the piston, and the ignited mixture escapes through passages 38, 49 in the piston and the cylinder wall to the turbine 17. The sprayer 43 is supplied from a fuel-pump driven by an eccentric on the shaft 16, and the fuel supply is controlled by a governing-device comprising a. piston valve 65, Fig. 3, connected to a centrifugal governor 64 driven from the shaft 16 through bevel-gearing 77 and belt gearing 74. When the speed is excessive, the pistor 65 cuts off the outlet 72 leading to the fuel-sprayer, and the fuel escapes to the supply tank through passages in the piston and through an outlet 78<a> fitted with an adjustable spring-loaded valve. This valve serves also to maintain constant the pressure of fuel normally supplied to the sprayer. The fuel supply to the sprayer may also pass an adjustable needle valve and a rotary engine-driven valve which opens at the requisite point in the stroke of the main piston 5. In order to cool the piston 5, a tubular extension 97 of the piston-rod reciprocates in a water inlet chamber 100 carried by a frame 8. The water passes through the pistonrod and through passages 102 in the piston and escapes through a. port 4 in the bed-plate 3. The cylinder 1 may have a water jacket 103.
