Abstract: 702,598. Heat treating silicon steel. ARMCO INTERNATIONAL CORPORATION. Sept. 18, 1950, No. 22911/50. Class 72 A process of producing silicon steel of high and highly directional permeability comprises hot rolling silicon steel containing 2-4.5 per cent. silicon to a thickness of. 0.05 to 0.14 inches cold rolling, annealing the steell at 1500-2100‹F., again cold rolling with a reduction in thickness of 0.4 per cent. to 2.0 per cent. and box annealing at 2050-2300‹F., the reduction in the first cold rolling being not less than 70 per cent. and not greater than the value of "y" in the equation where "x" is the temperature of the intermediate anneal. There are four variables affecting the final. results, 1 the hot rolled thickness of the starting material, 2 the amount of reduction in the first stage cold rolling, 3 the temperature of the intermediate anneal, 4 the amount of redaction in the second stage cold rolling. As shown, the shaded area represents the conditions for obtaining a permeability of over 1700 for material having a starting thickness of 0.062 inches, the ordinates representing the reduction during the first cold rolling and the abscissae the temperature of the intermediate anneal, the slope of the line "B" being the value of "y" in the above equation. The dash-dot line "C" represents the maximum permeability obtainable in which case the reduction in the second stage cold' rolling is varied inversely with the temperature of the intermediate anneal.

Title: Improvements in or relating to control systems for electrical apparatus, such as motors
IPC: H02P1/04
Filed: 1925-09-21
Abstract: 261,507. Scarf, C. T., and Metropolitan- Vickers Electrical Co., Ltd. Sept. 21, 1925. Cut-out arrangements. - In a protective control system for coal-cutting machinery, the manual operation of the reversing control switch 24, 25, 26 located near the motor causes the subsequent operation of a pilot switch 28 connected therewith, the pilot switch serving to complete a low-voltage circuit (deriving its energy from a transformer 43, 46 across a pair of the phases) to energize, through the earthed armouring 42, 41 and a pilot wire 48, 49 of the five-core trailing cable, the closing coil 47 of a closing relay 52 for the remotely disposed main circuit-breaker. The closure of the relay 52 completes the circuit across the phases 2, 3 of the closing coil 50 of the main circuit-breaker. In this circuit the contacts 51 of a normally closed no-volt relay are arranged, its operating coil 54 being connected across the phases 2, 3 through the contacts 55 of a leakage relay and the contacts 56 of an overload relay. The leakage relay is energized by the secondary coil 6 on the core 5 when a leakage occurs in any one of the phases a turn of each of which is taken round the core, as shown. The overload relay has a core energized by turns 121, 122 of two of the phases. In the event of leakage or overload, the no-volt relay assumes the off-position and, in consequence, the closing coil 50 of the main circuitbreaker is de-energized. The no-volt relay can be reset by closing the push-button switch 53. In stopping the motor in normal working the operating handle 60 first opens the pilot switch thereby causing the opening of the main circuitbreaker. In order further to ensure that the power circuit is never broken at the control switch, an electromagnetic latch device is employed consisting of a core 27 energized from one of the phases and serving to engage a sector 62 on the spindle of the operating lever 60 and thereby lock the lever while current is flowing.

Abstract: 726,401. Mullers. WESTIN, K. G. Sept. 1, 1953 [Sept. 11, 1952], No. 24154/53. Class 59. A muller for foundry sand comprises a drum 1 having a feed opening 15a at one end for the sand and a discharge opening at the other end, and a rotary shaft 13 to support a plurality of crushing elements 17 and scraping elements 19 which are at different axial positions throughout the drum and act on the sand at the wall of the drum during rotation of the shaft. An electric motor 11 drives the shaft 13 through a worm gear or the like 12 and effects feed of the sand by a worm conveyer 14. Each mulling and scraping unit has a hub 21 to support diametrically-opposed mulling wheels 17 and scoop scrapers 19, and three units are arranged along the shaft, with the wheels of adjacent units offset from each other by about 60 degrees. The wheels are mounted loosely on the cranked ends of their supporting arms 18 or on eccentrics on the cranked ends so as to be applied resiliently against the sand by centrifugal force. Vanes 19a may also be provided and so arranged with the scoops 19 that the entire length of the drum may be scraped. The rate of feed of the sand along the drum can also be controlled by regulation of the angle of the scoops 19 and the vanes 19a which may be arranged to return the sand for further treatment. The feed may also be assisted by inclining the drum at an angle up to 15 degrees to the horizontal. This may be effected by pivoting a frame 3, 4, supporting the drum, about bolts 5a, by means of a screw, hydraulic or pneumatic, jack 9. The drum may have a wear-resistant lining, e.g. of rubber, and at least one access door which may be operated by a pneumatic or hydraulic jack. A current of air may be passed through the drum preferably from an inlet 23 to an outlet 24, to cool the sand and remove entrained dust, and water may be introduced through nozzles adjacent the inlet end of the drum to moisten the sand. The drum may be of conical form.

Title: Improvements relating to the manufacture of fuel briquettes
IPC: C10L5/02
Filed: 1926-09-30
Abstract: 282,890. Bowen, E. W. Sept. 30, 1926. Composition fuel.-In briquetting anthracite or other coal or coke or mixtures with waste sulphite liquor, the fine dust or flour is separated from the granular part of the fuel while dry and is introduced into the mixture of granular fuel and liquor. The material is conveyed from a dump A to a hopper C and thence to a hopper D arranged above a drier E heated by combustion products from a boiler S. The fine dust, separated as by means of an upward centrifugal draught within the drier, is discharged into a bin F and the granular material passes to a screen G of about 8 mesh which may include a magnetic separator. From a roller crusher the granular material enters a high speed screw conveyer I where it is moistened with sulphite liquor at 150‹ F. from nozzles J. The mixture passes to a second conveyer K into which a proportion of the fine dust is introduced. The plastic mass is fed to a press L, the formed briquettes passing by way of a conveyer band M to the conveyer N of a drying furnace O. The boiler S may provide steam for heating the liquor and operating steam jets. A producer consuming the briquettes may supply gas to the boiler and drying furnaces. In an example, 86 per cent by weight of granular material is mixed with 9 per cent of liquor and 5 per cent of dust is added thereto. The briquettes are baked at 630‹ F. for 22 minutes.

Title: Improvements in or relating to capacitors
IPC: H01G4/12
Filed: 1964-06-11
Abstract: <PICT:1058689/C6-C7/1> A capacitor is formed on a ceramic surface 2, which may have a peak to valley distance 5 between thirty five and one hundred micro-inches, by depositing a refractory metal film 4 on the surface, inserting the film in an electrolysis cell and anodizing it at a constant current density, reversing the applied polarity briefly when the cell voltage becomes constant, and finally depositing a conductive metal film 8 over the anodized portion 6. The first metal film 4 may be tantalum, niobium, titanium or bismuth deposited by cathode sputterring, vacuum evaporation or electroplating to a thickness of between ten and fifty micro-inches. The second film 8 may be gold, tin, zinc or aluminium vacuum evaporated to a depth of several thousand Angstrons.  The anodizing process is carried out in a conventional electrolytic cell, and when the formation voltage approaches a constant value, after ten to twenty minutes, the voltage is applied for about half a minute with the magnitude half the peak magnitude and the polarity reversed.  The effect of the polarity reversal is to activate previously passive spots on the film, resulting in a more uniform oxide layer than could otherwise be achieved except with a much smoother ceramic surface. Consequently the tendency for the oxide film to crack, resulting in a short circuit, is lessened.

Abstract: 1357666 Pulse delaying circuits; distortion correction INTERNATIONAL BUSINESS MACHINES CORP 24 May 1972 [21 June 1971] 24382/72 Headings H3P and H4P A circuit for delaying leading and trailing edges of a pulse (e.g. to correct errors determined by a computer analyser or to predistort pulses for testing apparatus response) comprises means for producing signals corresponding to the leading and trailing edges of pulses, means for variably delaying each signal and means for reconstituting the pulses from the delayed signals. In Figs. 1a and 1b input pulses ABC, e.g. from a magnetic store or other multipath system are applied to a circuit 2 which produces pulses d1, d2, d3, &c. at the leading and trailing edges. These are fed to delay circuits #<SP>1</SP>, #<SP>2</SP>, #<SP>3</SP> having delays determined by a regulator 4 and appropriate output pulses from the delays are selected in accordance with a program applied at t1 t2, t3 to produce, for example, pulses d1<SP>1</SP>, d2<SP>1</SP>, d3<SP>1</SP>, &c. and these are fed to the trigger input of a bi-stable circuit T to produce the delayed pulses A<SP>1</SP> &c. An alternative "normal" delay circuit #0 may be selected at A having a delay intermediate other delays so that the pulse edges may be advanced or delayed with respect to "normal". In a multi-channel system (Fig. 3A, not shown) the delay circuits may be connected in series selectively and the resulting pulses directed to selected output lines. Each output circuit includes a bi-stable circuit (PHL) which samples the original input pulse in response to the delayed pulse trailing edge (Fig. 3c, not shown). The signals corresponding to the input pulse edges are produced by differentiating circuit followed by a diode polarity selector and an inverter (Fig. 2, not shown).
