Abstract: 912,887. Dielectric heating of resin-impregnated cloth. MILLVILLE MANUFACTURING CO. April 21, 1960, No. 14030/60. Class 39 (3). [Also in Groups VIII and XVI] In apparatus for processing a length of cloth to produce cut lengths thereof, a transverse band of resin is applied to the cloth at set intervals, the resin is cured by dielectric heating and cuts are made across the bands of cured resin. The power input of the dielectric heating circuit is in accordance with the formula where W=watts of power, E=voltage, F= frequency in cycles per second, C = capacitance of the load in Farads and P.F. = effective power factor of load. The heating apparatus includes a special circuit arrangement and a special electrode configuration. A main oscillatory circuit made up of cylindrical copper conductors Z10 is shown in Fig. 26. Z9 is the main tuning condenser and Z14 are plate blocking condensers. A control condenser Z16 permits small adjustments in the total electrical capacitance. These parts are shown electrically connected in Fig. 45 which shows a basic " Hartley " oscillatory circuit with an untuned impedance circuit grid Z8 and a tuned plate circuit consisting of condensers Z9, Z16 in parallel with inductance Z10. The electrodes are shown in Fig. 31 (not shown). Numerals 104,104<SP>1</SP>denote one set of electrode components and numerals 105, 105<SP>1</SP> denote a second set. These components consist of elongated bodies of semi-elliptical cross-section. They are preferably composed of aluminium and the lower components are mounted for vertical reciprocating movement. The lower electrodes have, at their ends, retaining clips which register with the respective upper electrode so as to locate them in precise position to prevent underirable arcing. The resin band VI is located intermediate the electrodes for the curing operation.

Filed: 1927-06-07
Abstract: 281,548. Wolff, F. June 7, 1927. Sparking-plugs.-The insulation is in two portions, that nearer to the combustion chamber being of heat-resisting material such as porcelain, glass, mica, quartz, steatite or fibre, and the outer portion 6 being of plastic material such as artificial resin, which is forced into position under high temperature and pressure. The metal casing may also be in two portions, the portion 2 having an internal flange 5 which serves as a bearing for the insulating materials, but through the middle of which the heating-resisting member projects into intimate contact with the plastic material. Indentations 7, 10, 11 may be provided to improve the contact and promote gas-tightness. In a modification the flange 5 is omitted, and the casing is in one piece with a dovetailed recess in its internal wall, the plastic material filling this recess and interlocking with projections on the inner insulator. In a further modification the plastic material encloses a sleeve into which the end of the conducting cable may be inserted, and which at its inner end is in electrical contact with the central conductor passing through the ceramic insulator.

Abstract: 856,085. Control of D.C. motors. OTIS ELEVATOR CO. May 4, 1959, No. 15139/59. Class 38 (3). [Also in Groups XXV and XXXVI] Fig. 6 shows the door motor-control system for a lift in which the doors open automatically when the cage is stopped at a landing and close after a predetermined time interval. For example, when the car reaches a landing which it is required to make a stop switch H drops out, thus releasing relay XNT after a period of time so as to energize switch DO so that the armature winding DMA of door motor DM is energized via contacts DO5, DO6, whilst contacts DO4 are opened. When the limit of the door opening is reached contact DOL opens, thus breaking the circuit of relay DO and stopping motor DM. At the end of a predetermined period relay XNT drops out and initiates the closing operations motor DM having its armature DMA energized via contacts DC2, DC4 and open contacts DC3. As the doors move a certain distance from the closed position the door speed limit switch DEL closes to energize relay DE which engages contacts DE3 to short-circuit resistance RDMF in circuit with the door motor field winding DMF and also short-circuits resistance RDM4 in circuit with the armature DMA of the dooroperating motor, this giving the desired control of the door motor DM. A detector system, Fig. 5 (not shown), (see Group XXXVI), is associated with the doors so if a person passes between them when the closing action is taking place, the detector relay changes-over contacts DP to break the circuit of door-close switch DC and thus of the armature DMA of the door-control motor DM. Contact DC3 also connects rectifier EDB in shunt with the armature to effect a braking action. Specifications 711,515 and 734,471 are referred to.
