[Class 125 (ii).] In apparatus for applying closures to. bottles &c., of the type comprising a pair of jaws adapted to grip the neck of the bottle, &c., a plunger for actuating said jaws, a closure - applying means, and means whereby the plunger and the closureapplying means can be operated by a common member, the plunger 27, shaped with a conical end, and the closure - applying means 38, are carried by a pair of parallel rods 30, 37, the upper ends of which are coupled to a common actuating member 31, which positively causes them to move downwardly, in unison. The plunger, Fig. 3, preferably formed adjustable at 29, causes the jaws 21, shaped at 22, to move inwardly against the spring 28 to grip the neck of the bottle &c. below a shoulder 14 formed thereon, which shoulder takes the bulk of the sealing pressure. The closure-applying head 38 and rod 37 are moved by ' a lever 34, carried by the shaft 33, which engages at 35 with an adjustably mounted block 36. The closure may be of the screw or crimped type, or of the type comprising a divided skirt contracted on to the bottle by a wire and lever which moves radially of the neck.

Title: Improvements relating to the smelting of iron ore
IPC: C21B15/00
Filed: 1947-08-13
Abstract: In a process of smelting metallic ores to produce a metal, p  small pieces of the ore are mixed with an uncarbonized, solid, cellulosic vegetable matter and heated to a temperature sufficient to reduce the ore.  Iron ore, alone or mixed with an alloying metal ore, in small pieces or finely divided, may be briquetted with an uncarbonized vegetable substance such as sawdust, straw, sugar cane bagasse, or rice bran, using coal tar, molasses, pitch, sodium silicate, milk of lime or milk of cement as binders and heated to produce iron or an iron alloy.  The heating may be in two stages, the first driving off the volatile constituents, which may be collected and burned and the second reducing the sintered lumps remaining.

Filed: 1967-05-16
Abstract: 1,177,540. Lateral transistors. SPRAGUE ELECTRIC CO. 16 May, 1967 [17 May, 1966], No. 22662/67. Heading H1K. In a lateral transistor having an emitter junction with a lateral area normal to the surface of the wafer and a planar area parallel to the surface, the lateral area of the emitter is much larger than the planar area, the collector junction has a lateral area at least as large as that of the emitter junction, the base region is about 1Á thick, and the charge carrier recombination occurs mainly within the body. A PNP lateral transistor is produced by oxidizing the surface of a silicon wafer, photomasking and etching, exposing to an atmosphere of B 2 H 6  + 0 2  + N 2  to predeposit boron, heating in nitrogen to drive in the boron, and annealing to reduce the recombination rate at the silicon-silicon oxide interface. The lifetime of carriers in the bulk material can be increased by electroless plating nickel on to the back of the wafer after the predeposition step. The lifetime may be decreased by vapour depositing gold on to the back of the wafer after the predeposition step, heating in nitrogen, and rapidly quenching. The electrodes are applied by etching windows in the oxide, evaporating-on a layer of aluminium and selectively etching. The device may have the circular geometry shown in Fig. 4 in which the emitter region 12, provided with an electrode 22c, is surrounded by a narrow base region 15, and by the collector region 13, provided with an electrode 23c. Alternatively the device may have a geometry as shown in Fig. 5, where the emitter region 32 is flanked on both sides by base regions 15 and collector regions 33, all in the form of parallel strips. In either geometry the base contact (not shown) is applied to a convenient part of the bulk substrate 11. It is stated that the emitter and collector regions can also be produced by alloying.

Electromagnetic current and pressure meters.-A current indicator for train-lighting and like dynamos comprises a solenoid having more than one core arranged to operate indicator plates at different values of the current. As shown in elevation in Fig. 1 and in section on the line II-II in Fig. 2, a solenoid d is provided with two iron cores h, h<1> which are arranged to be sucked up by the solenoid at different values of the current, being for this purpose made of different weight, or differently loaded, or, as shown, one core h is supported' on an adjustable stop j at a higher elevation than the other core h<1> The cores h, h<1>, when sucked up, strike non-magnetic pins r, r<1> passing loosely through bushes e<1> having rounded heads r<2>, which strike trip lever arms n, n<1> carrying curved indicator plates o, o<1>, which are thereby caused to fall and cover a fixed indicator plate m. The core h is adjusted to operate at the normal current, thereby causing the plate o to cover the fixed plate m. On the normal current being exceeded by a predetermined amount, the core h<1> is operated and causes the plate o<1> to cover the plate o. When used in connection with a train-lighting dynamo driven bv a slipping belt, the plates m, o, o<1> may be marked respectively to indicate that the tension of the belt is " too loose," " right," and " too tight." The plates o, o<1> may be reset by an electrcmagnet q excited by a highresistance winding p which is connected across the mains when required. A calibrated or variable shunt may be provided for the winding of the solenoid d to permit alteration of the output values under which the solenoid is operative.

Abstract: 533,450. Nuts. BESWICK, R. E. Aug. 14, 1939, No. 23350. [Class 89 (i)] Quick action nuts comprise a number of segments 10, Fig. 4, each attached to one arm 11 of a spring cage having an opening 17 to pass the bolt. The cage is a sheet metal stamping and may be reinforced by a second stamping 18a. Each segment comprises one whole face and two part faces of a hexagon and the segments are closed on the bolt by a sleeve 12 formed internally to fit the segments and externally to receive a spanner. The engaging faces of sleeve and segments may be tapered to facilitate expansion of the cage but the taper must be within the angle of friction. Rounding at 46 facilitates closing the segments. Projections 11a on the cage prevent accidental separation of cage and sleeve. In a modification shorter overall length is secured by joining the arms forming the cage in a washer 20, Fig. 5, the arms being bowed at 25. The sleeve may be formed as a wing nut in any of the forms. In other modifications the overall length only exceeds that of the segments by the thickness of the sheet metal forming the cage.

Abstract: 963,410. Solion integrators. GENERAL ELECTRIC CO. June 18, 1962 [June 28, 1961], No. 23437/62. Heading G1Q. [Also in Division G4] A solion device used for determining the time integral of a current has platinum electrodes 16, 17, 18 and 51 which are arranged between a series of parts made from heat resistant glass consisting of a top closure member 11<1>, a perforated separator 12<1>, a porous frit member 13<1>, a further separator 14<11> and an additional frit member 13<11>. The integrator portion of the device consists of a sputtered platinum layer 19<1> applied to the frit 13<11> as one electrode and a further electrode 20<1> sputtered or fixed into the recess 54 in the glass base member 56. A ring of platinum mesh 57 which in assembly contacts the layer 19<1> is also included. In assembly the separate parts are all fitted together with a surrounding glass sleeve 59 and the assembly is heated so as to fuse the parts together. Thereafter the assembly is filled through the stem in the top member 11<1> with a chemical solution of potassium iodide and iodine, and sealed off. The operation of the device may be explained with respect to Fig. 3, reference to electrodes 16 and 51 being omitted. Electrode 17 which is the input cathode, acts as a separation anode with electrode 18 as the cathode energized from battery 60. Iodine is reduced at the electrode 18 to iodide and iodide is oxidised to iodine at the electrode 17, so that separation of iodide below electrode 18 and iodine above electrode 18 occurs. The process may be speeded up by also connecting electrodes 19<1> and 20<1> to a negative potential. A battery 61 is connected with its negative side to the electrode 17 and its positive to the electrode 20<1> so that the change of concentration of iodine at the electrode 20<1> as iodide is oxidised is a function of current flow according to Faraday's Law. Because the free iodine concentration in the integrator chamber increases during the redox process, when a battery 62 and ammeter 63 are connected between the electrodes 19<1>. (cathode) and 20<1> (anode) the change is indicated on the meter as an output current proportional to the integral value of the input current from the battery 61.
