Title: Improvements in and relating to systems of electrical distribution
IPC: H02J1/08
Filed: 1922-11-24
Abstract: 211,586. British Thomson-Houston Co., Ltd., and Whitaker, F. P. Nov. 24, 1922. Switching systems.-Converters and generators are connected up successively, after a complete shut-down of the system, through resistances which are short-circuited wholly or in sections after all the converters or generators are connected up. When a transformer and a neutral wire connected thereto are employed, the circuit of the neutral wire is completed when the last section of the resistance is short-circuited. Converters or generators 10, 11 and 12, Fig. 1. are connected successively to the supply mains through switches 1, 2 and 3 and resistances R<1>, R<3>; R<4>, R<6> and R<7>, R<9> by the closure of a switch 13, Fig. 2, which energizes the coil 1<A> of the switch 1. The operation of the switch 1 closes an interlock switch 1<B> to energize the coil 2<A> of the switch 2 the operation of which closes an interlock switch 2<B> to energize the coil 3<A> of the switch 3. The operation of the switch 3 closes a switch 3<B> to complete the circuit containing a coil 8, switch 4<B> and the operating coil 4<A> of contactor 4 controlling sections R<2>, R<3>; R<5>, R<6> and R<8>, R<9> of the resistances R<1>, R<3>; R<4>, R<6> and R<7>, R<9>. The ampere-turns of the coil 4<A> are not under this condition sufficient to operate the contactor 4 but the coil 8 removes a support for the plunger of the coil 6 connected in series with the coil 7 in the line. When the current in the coil 6 drops to a predetermined value a contactor 6<A> closes a second circuit for the coil 4<A> which operates to close the contactor 4. To retain the contactor 4 in its closed position it is provided with an interlock switch 4<c> and also with interlock switches 4B, 4D. The switch 4D closes a circuit containing a coil 9, switch 5<B> and coil 5<A> of the contactor 5 which short-circuits the remaining sections of the switching resistances. In the three-wire system shown in Fig. 4, a switching resistance is placed on each side of the neutral wire which is connected to the middle points of transformers through switches 14. The switch 14 is operated by a coil 14<A> the circuit of which is controlled by a contactor 5<c>, Fig. 5. The switch 14 may be operated by hand.

Title: Improvements in or relating to liquid level indicator
IPC: G01F23/26
Filed: 1955-11-11
Abstract: 796,188. Electric tests. ARO EQUIPMENT CORPORATION. Nov. 11, 1955 [Aug. 15, 1955], No. 32287/55. Class 37. In a liquid level indicator using the dielectric properties of the liquid to change the capacity of a condenser as the height of the liquid varies, the condenser forms part of an L-C resonant circuit which is connected in parallel with an indicating instrument supplied with the output from a fixed frequency oscillator. As shown, the amplified output from a crystal oscillator is fed through a blocking condenser 33 and rectifier 35 to a voltmeter 36. In parallel with meter 36 is a resonant circuit consisting of an inductance 46, a capacitance 47 and a variable capacitance provided by plates 12, 13 which dip into the liquid 11 in a tank 10. The resonant frequency of this L-C circuit is arranged to be higher than the oscillator frequency when tank 10 is empty so that minimum voltage is then applied to meter 36 whereas the impedance offered by the L-C circuit to the oscillator output rises with increase in the liquid level and the meter reading increases. A potential divider 38, 41 connected to a D.C. source 23 applies a D.C. voltage across the meter in opposition to the amplified oscillator output an adjustable wiper 39 being provided to adjust the zero setting of the meter when tank 10 is empty. The measuring range of the meter is variable by a wiper 43 as in resistor 42.

Title: Hoisting means with slewable boom and tackle, particularly for use in the building industry
IPC: B66C23/22
Filed: 1964-08-10
Abstract: 1,023,118. Builder's cranes. F. DURST. Aug. 10, 1964 [Aug. 8, 1963], No. 32463/64. Heading B8B. A builder's crane with a jib 31, Fig. 1, may be slewed by hand to bring a load 43 within reach of a building 2 thus causing a rocker 25 which supports the jib to pivot clockwise about a shaft 24 to a stable position from which there is no tendency for the jib to slew outwards. Sideways swinging of the load during hoisting is prevented by a spring 56, Fig. 2a, which holds a lug 54 against an adjustable pin 53. If the bucket 43 is raised too high a lever 42, through which the hoist rope passes, is raised to break an electrical circuit controlling the winch. The hoist rope 17 passes from the winch over a pulley 40, up through a slewing tube 29 and over pulleys 38, 37. The pulley 40 is mounted in a bracket 41 which is pivoted clockwise by a spring 44 when the rope 17 goes slack due to the load being set down, thus operating a switch which stops the winch. The winch 16, Fig. 1, is mounted on a rod 1 supported from the building by members 20, 22. The load is prevented from descending when the winch is stopped by self-locking worm-gearing in a gear-box between the motor and the winch. In addition, a brake belt 14 acts on a wheel 12 mounted on the motor shaft. The wheel 12 free-wheels whilst the motor is driving. The crane may be dismantled for transport.

Title: Improvements in or relating to shoemaking
IPC: A43D87/00
Filed: 1932-11-17
Abstract: 410,512. Boots &c. BRITISH UNITED SHOE MACHINERY CO., Ltd., Belgrave Road, Leicester.-(Assignees of Goddu, G. ; Winchester, Massachusetts, U.S.A.) Nov. 17, 1932, No. 32499. Convention date, Nov. 20, 1931. Addition to 355,332. [Classes 17 (i) and 17 (ii).] Connecting uppers to insoles and soles.- An insole for use in the method of cement lasting shoes described in the parent Specification is channelled inwardly around its edge face around the forepart from heel breast to heel breast parallel to its bottom face, and at a distance therefrom equal to the thickness of the upper materials, to form a feather of sufficient width for the adhesive attachment of a shoe upper. The outer part of the lip so formed may be cut off and the remainder is turned inwardly on to the body of the insole and set in that position, e.g. by coating its outer face, as shown in Fig. 4, with stiffening material, such as shellac containing acetone, e.g. in the proportions :-3¢ quarts of denatured alcohol, 3 pounds of shellac and 1 pound of acetone. This stiffening renders the lip more resistant to outward bending by tension of the lasted upper. As shown in Fig. 4, the lips may overlie one another at the shank. Lasting is performed as described in the parent Specification, cement being omitted from the inner face of the lining from ball to breast line but a liberal coating is applied to the corresponding parts of the leather of the insole to prevent adhesive spreading to that part of the lining which will be visible in the finished shoe. The lip of the insole is turned up by the lower anvil of the stapling mechanism of the side-lasting machine which is shaped to deflect the legs of the staple fastenings upwards. At the toe end of the shoe, a binder 58, Fig. 7, of known form with its vertical flange 60 of reduced height at the extremity 62 so as not to be obstructed by the upper parts of folds which may be formed in the marginal portion of the toe of the upper during lasting, is held in position while the cement is setting by a T-shaped lever 64. A tack 78 is driven into the insole through one of a series of perforations 76 in the leg 70 of the lever 64 to hold it with its arms 68 bearing evenly on the toe binder. The upper materials and lip may be left untrimmed at the shank and beaten down on to the insole to accommodate a convexly curved shank stiffener between the sides. An outer sole may be attached by cement or by through stitching. Specifications 24674/06, [Class 17], and 283,978, [Class 17 (i)], are referred to. The Specification, as open to inspection under Sect. 91 comprises also a construction for a narrow-shanked shoe wherein a single lip only is provided at that locality for the attachment of the upper materials. This subjectmatter does not appear in the Specification as accepted.

Filed: 1975-08-05
Abstract: 1524362 Producing iron melts HITACHI METALS Ltd 5 Aug 1975 [9 Aug 1974 30 April 1975 (2)] 32730/75 Heading C7D Ferrous scrap is melted by charging a solid carbonaceous material eg graphite, pitch coke, to the bottom of an electric arc furnace, and adding the scrap and a material to form an oxidizing slag, such that as the scrap melts, it falls as droplets through the slag to form a melt, which is then recarbonized by the solid material. The slag 3 which removes Cr, Mn and Si from the droplets 7, is formed from solid slag-forming agents (eg iron ore, or the unreduced ore in sponge iron) and/or O 2 , blown after melting commences, with or without entrained iron ore. The recarbonization occurs at the interface 4 of the melt 2 and material 1. The scrap charge 6 comprises steel scrap with iron scrap and/or sponge iron. The melting is carried out below 1440‹C. In Examples, the charge is melted at 1350-1360‹C, the slag removed, and recarburized at or over 1500‹C. The melt produced is then treated to produce a spheroidal graphite iron having a ferrite matrix on casting.

Title: Improvements in apparatus for drying coated or enamelled paper, waterproofed cloth and such like
IPC: D21F5/00
Filed: 1919-12-31
Abstract: 160,940. Howden, C. F. Dec. 31, 1919. Drying fabrics and materials in long lengths.-In a stage drier for coated or enamelled paper, waterproofed cloth, &c. passed through a drying-chamber, the drying-air is heated in separate stages, the initial temperatures of which are progressively less stage by stage. Vacuum drying-pads are provided and a device for cutting out the supply of hot air in case of breakage of the web. The apparatus shown in Figs. 1 and 1<a> comprises a casing 1 formed with perforations 2 - - 5 above which air casings 6 - - 9 are mounted having inclined roofs and containing heaters 14 - - 17. Air-inlet pipes 18, 19 communicate with the casings 6, 9 and an outlet pipe communicates with the casing 1 between the casings 6, 7. The casing 1 communicates with the casings 7, 8 by openings 21, 22. The paper &c. passes from a coating-drum 44 through the casing 1 to a reeling-drum 45, and is dried by air drawn in by fans through the pipes 18, 19 and passing over the heaters and through the perforations 2-5 and openings 21, 22 to the outlet pipe 20. An additional drying effect is also produced by means of " vacuum pads " 31 within the main casing, each formed of two rollers 32, 33, Fig. 8, surrounded by a perforated endless band and enclosing a perforated chamber connected to a suction main. In a modified form of apparatus, the main casing is divided into three compartments each provided with an external air heater and external pipes from which air is supplied through nozzles projecting into the casing. Moist air from the first compartment is exhausted to atmosphere; the other compartments may utilize either open or closed circuit. Rollers maintain the web in contact with the vacuum pads. To prevent scorching in case of breakage of the web, a lever is provided, one arm of which comprises a cam 78, Fig. 4a, engaging a roller 77 connected by a chain 74 with a damper by which air may be caused to enter the first compartment either direct from atmosphere or through the heater; the other arm of the lever carries a roller normally supported by the web, breakage of which allows the cam to disengage the roller 77 and the damper to be shifted by a weight. In a further modification, two compartments are disposed side by side above a third compartment from which they are separated by a partition in which the vacuum pads are arranged; the web passes horizontally over and under the partition and in contact with the pads which are perforated above and below; air is directed from above through nozzles and from below through perforations in a pipe.
