IPC: H01B17/26
Filed: 1929-01-29
Abstract: 306,894. Bosch Akt.-Ges., R. Feb. 27, 1928, [Convention date]. Condensers. - An electric lead-in, particularly for condensers for ignition apparatus, comprises a rivet lead-in held in place against an insulating washer by a spring washer, so as to make a fluidtight joint. In the construction shown of a paper wound condenser for magneto ignition apparatus, a metal box a is centrally apertured in one end for a rivet h. An internal insulating washer e centres the rivet h, and a metal washer d is pressed against the free face of the washer e. Outside the box an insulating washer f is placed on the rivet, and held in place by a spring washer g, over which the rivet h is riveted. A layer of semi-plastic material l, such as varnished silk, is preferably placed between the washer f and the box a, to fill up small irregularities. The condenser c is placed in the box with an insulating sleeve i, a spring k<1> ensuring contact of one coating with the leadin. The contact of the second coating with the housing is ensured by a spring k<2> over which a metallic cover b is spring, or soldered in, to the box a.

Title: Improvements relating to plate-type heat exchangers
IPC: F28F3/02
Filed: 1957-01-28
Abstract: 805,215. Plate type heat exchangers. DAIMLER-BENZ A. G. Jan. 28, 1957 [Jan. 30, 1956], No. 3032/57. Class 64(3) Relates to a heat exchanger in which the heat exchanging media, one of which is at a higher pressure than the other, flow in counter-flow or in cross-flow relationship between spaced plates 10-14, and wherein corrugated sheet metal elements connected to the plates, are so disposed between the plates as to form ducts extending in the direction of fluid flow between adjacent plates, the said elements having interruptions in the direction of fluid flow, at least in the region not bearing against the said plates. According to the invention, the corrugations of the sheet metal elements 17, 18 providing ducts for the medium of lower pressure have parts of rectilinear section extending from plate to plate, and the corrugations of the sheet metal elements 15, 16 providing ducts for the medium of higher pressure have substantially S-section parts extending from plate to plate. This arrangement it is stated permits slight changes in the distance between adjacent plates due to the differences in fluid pressure without causing the corrugated members to become detached from the plates. Those portions of a duct which are separated from one another by the interruptions in the duct walls may be offset from one another transversely to the direction of fluid flow.

Abstract: 124,244. Hope, G. F. W. Feb. 20, 1918. Rotary sieves.-Relates to rotary drum apparatus for drying sand &c. The material is fed from a hopper 2 through a shoot 12 into a rotating perforated or open-work drum 1 provided internally with beaters 5, Fig. 2, and pivoted shelves 10. The shelves are supported by chains 17 so that they fall back as the drum revolves. The beaters 5 have looped ends 6 which engage the shaft 4 and are thus free to move to a certain extent at right-angles thereto. The beaters are lifted by angle-pieces 9 carried by the drum and, when raised sufficiently slip inwards and clear the angle-pieces. Material escaping through the openings in the drum is received by one or more oscillating plates 13 actuated by a cam 14 and heated by gases from a furnace 16. The material passes to another plate 15, which may also be oscillated, and is delivered to a conveyer. The drum is driven through toothed gearing 7, 8 or otherwise. The shoot 12 is rocked by the passage of the trays over it. An adjustable gauge may be arranged between the plates 13, 15.

Abstract: 563,784. Uniting metal to glass by heat. STANDARD TELEPHONES & CABLES, Ltd., WOLFSON, H., and SHEPARD, S. C. Feb. 24, 1943, No. 3060. [Class 36] The electric wires 1, 2, 3, 4, Fig. 3, which may form part of a thermistor, Fig. 1, are sealed into a glass bulb 9 by mounting the wires, which are passed through a glass bead 5, in a jig 13 supported by a rod 14 fixed to a rotating platform 15. The bulb 9 is placed over the assembly and rests on the jig 13. As the bulb rotates, its end is heated by a gas-oxygen flame 17, and the glass softens and flows to close the end of the bulb. The bulb 9 is held by a clip 16 which can prevent the bulb from falling by gravity, or which can permit pressure to be applied to the end of the bulb to press it into a mould. The jig and associated devices may be arranged to rotate around a horizontal axis. The bulb is finally sealed after evacuation or gas-filling. The thermistor comprises a resistance bead enclosed in a heater coil 8, the leads of which are connected to the wires 2, 3 and leads 6, 7 from the resistance bead are connected to leads 1, 4. The bead is a semi-conductor which possesses an abnormally high resistance temperature coefficient, either positive or negative and may have a size equal to that of a pin head.

Filed: 1922-02-03
Abstract: 194,499. Beames, H. P. M., and Grover, F. M. Feb. 3, 1922. Steam-pressure sprayers.-In a spray burner comprising an upper oil compartment A and a lower superheated steam compartment B the oil flows over a flat surface or ledge C in the upper compartment and falls in a thin film past a series of steam jets J issuing from holes G in the lower compartment and is partially atomized thereby. Fuel not atomized by the jets J drops on to a fan-shaped tray D formed by the extended upper wall of the steam compartment B and flows along fluted channels E to the edge F, over which it falls into the path of a steam jet K issuing from a slot H extending the full width of the tray D. The two streams of atomized fuel converge and impinge on each other. The jets J may diverge laterally to spread the flame. The construction may be modified so that more than two streams of atomized fuel' from a burner or burners converge and impinge on each other.

A torsion magnetometer is supplied with temperature compensation by the use of suspension threads of different thermoelastic properties and of such dimensions that with variations in temperature the changes in torque in the suspensions are equal and opposite to the corresponding changes in the magnet system. Thus, for measuring a horizontal field, the magnet 1 (Fig. 1) is suspended from a calibrated torsion head 2 by two threads 4, 5 joined endto - end, of different materials, e.g. quartz and tungsten, and of such diameter and length as to produce temperature compensation for the magnet. In a modification (Fig. 4), the upper portion of the thread comprises two lengths of thread 4a, 4b whose effective lengths are adjustable by a connector 18 movable in a slot 19 in a cross-bar 17. Alternatively the threads 4a, 4b may be connected to individual torsion heads. For measuring vertical fields a magnet 9 (Fig. 3) is supported from two torsion heads 7, 8 by two selected threads, or one suspension may comprise a two-part thread 10a, 10b providing magnetic torque compensation, the other thread 11 providing mechanical torque compensation. The torsion head 8 may be provided with two predetermined, adjustable stop positions to give appropriate mechanical torque compensation for vertical and horizontal field measurements.

[Class 38 (iii).] Master control systems.-In a control system for a compound wound motor A for propelling a vehicle in which a master controller P regulates the series resistance R1 .. R4 and the shunt field resistance r1 .. r4, an overvoltage relay V is provided for reducing the shunt-field excitation when the regenerated voltage is excessive. When the master controller is moved to position 1 coils N1, N2 are energized and the line switches L1, L2 closed. In moving from position 1 to position 5 contactors H1 .. H4 are energized to gradually short-circuit the series resistance R1 .. R4, and in moving from position 5 to position 9 contactors C1 .. C4 are energized to gradually decrease the shunt-field excitation. If, while the motor is running at full speed, the controller is suddenly moved from position 9 to position 5 the motor will regenerate at high voltage and actuate the relay V to open the circuit of the contactors C1 .. C4 and of the coils N1, N2, so that the shunt field excitation is decreased and the motor circuit opened. An aluminium cell E is provided to allow a discharge if the voltage generated reaches a predetermined value in excess of the line voltage while the contactors C1 .. C4 are opening. A reversing switch K is provided with contacts K5 to open the motor circuit and contacts K6 to reduce the shunt excitation when the armature connections are reversed. An emergency switch may be provided for placing a series braking resistance across the armature which is cut out step by step by contactors of the type disclosed in Specification 11349/11, [Class 38 (iii), Electric motor control systems &c.].
