Abstract: 708,783. Operating coke-oven doors. WOODALL-DUCKHAM VERTICAL RETORT & OVEN CONSTRUCTION CO. (1920), Ltd. May 21, 1953 [May 22, 1952], No. 13028/52. Class 55 (1) In a coke-oven door operating machine, a latch bar pressure screw actuating unit, comprising an electric or like motor 15 and a universal joint 14 of, for example, the kind described in Specification 499,099 is adjustably mounted and is guided if necessary, so that the flared operating socket 12 engages a latch bar pressure screw 11 of a door 3, despite the misalignment of the screw 11 with the axis of the unit, and tightens or loosens it. A cradle containing the unit is pivoted at 17 about a horizontal axis between brackets 18 which depend from a circular plate 19 pivoted about a vertical axis to the head 6 of the door operating machine. An arm 37 which may be adjustably mounted on the cradle extends beyond the socket 12 and engages a ramp 36 on those doors having pressure screws above the lowest level of screws in a series of doors. The co-operation of the roller on the arm 37 with the base and sides of the ramp 36 aligns the socket 12 with the screws 11. Returning springs 21, 28 restore the unit to its original. after it has been deflected. In another form the unit is mounted in parallel links so that a translatory movement rather than a rotatory one is effected. The arm 37 and the ramp 36 may be reversed in position and the ramp is adjustable vertically and horizontally. Specification 619,021 also is referred to.

Abstract: 717,787. Optical mirror systems. SIEMENSREINIGER-WERKE AKT.-GES. May 23, 1952 [May 25, 1951], No. 13161/52. Class 97(1) In an optical mirror system for strictly aplanatic achromatic image formation, more particularly for X-rays, aspherical reflector surfaces S, S<SP>1</SP> and a central diaphragm B are so disposed in relation to the optical axis F<SP>1</SP>, F<SP>2</SP> of the system that the image formation is effected, with the exclusion of the central rays by rays remote from the axis the optical paths of which have components parallel to the axis in the same direction and which are predominantly totally reflected. The reflector surfaces may comprise a polygonal surface formed from aspherically curved strips which are disposed around the optical axis, each strip being, formed by displacement of a line along and perpendicular to calculated lines of curvature. The system may be used with radiation other than X-rays, e.g. infra-red waves, high-frequency radio waves, neutron and other corpuscular beams, and supersonic longitudinal waves. The surfaces may be machined, and in addition substances may be deposited thereon in thin or graded layers by vaporization, sedimentation or electroplating. Surfaces of small curvature may be obtained by bending by piezo-electric, magneto-strictive, or thermal effects.

Abstract: 1460603 Electric hot-plate CORNING GLASS WORKS 26 March 1974 [28 March 1973] 13317/74 Heading H5H To ensure even temperature and uniform power density throughout the area of a glass or ceramic topped hot plate, the heating resistor 13 which is a deposit of linear positive temperature material is subdivided into a plurality, e.g. nine, of contiguous equal area, equal resistance sinuous strips 14 connected electrically in parallel between a pair of supply terminals 21, 22, by a plurality of bus bars 15-20 of the same material as the strip portions 14, which bus-bars are graded in width stepwise depending on the number of strip portions 14 directly connected thereto. In the drawing it is seen that bus-bars 15 and 16 which are the widest are each directly connected to three strip portions 14, that bus-bars 17, 18 and the central vertical bus-bars 15a, 16a which are narrower are each connected to two strip portions 14 and that bus-bars 19 and 20 which are the narrowest are each connected to one strip portion 14. The hot plate resistor may be subdivided into greater number of equal area resistor strip portions connected in parallel between a pair of terminals by a plurality of stepped bus-bars, (Fig. 2, not shown). These arrangements ensure that if a pan is off centre on the hot plate then overheating of the uncovered part of the hot plate is avoided.
