Patent GB-890668-A (GB)
Title: Zone refining apparatus
Inventor: FRITTS ROBERT WASHBURN
IPC: H01L35/00
Filed: 1959-12-03
Abstract: <PICT:0890668/III/1> Zone-refining of a solid body is effected by means of one or more thermoelectric heat pumps, each pump comprising a thermoelement, e.g. a rectangular block of one of the materials described in Specification 814,594, sandwiched between a pair of thermojunction plates.  The direction in which current is passed through the pump from plate to plate is determined by whether the element is of N- or P-type and the direction of travel of the pump. In one embodiment (Fig. 1) the pump is passed through an elongated block of material to be purified in an open container, material being melted by heat emitted by the leading plate, passed round the pump, and solidified by extraction of heat by the other plate. In the second embodiment (Figs. 2 and 3, not shown) four P-N double heat pumps are situated crosswise between two elongated blocks arranged in staggered relationship so that on termination of a pass the unrefined portion of each block is molten.  In this embodiment, two successive molten zones are passed through each block, each molten zone in each body being produced by the heatemitting end plates of one double pump and solidified by the heat-absorbing end plates of the next double pump.

Abstract: 1,244,375. Concrete reinforcing lattice beam, concrete beams. JOHN LAING & SON Ltd. 27 Aug., 1969 [28 Aug., 1968], No. 41175/68. Headings E1K and E1W. [Also in Division B3] A structure for connecting two or more longitudinal bars 4 of a lattice girder or like concrete reinforcing member, is wound from a continuous element 1, the winding progressing throughout the same longitudinal direction with a series of repeated configurations (as viewed from an end of the girder), which series defines an aligned series of loops 5 for each longitudinal bar 4. The successive repeated configurations are initially closely positioned, and after threading the bars 4 through the loops 5, the structure is axially expanded along the bars, the diameter of the loops 5 being thereby reduced so that the loops 5 grip the bars 4. Two such wound structures may be used with one set of longitudinal bars, such structures being shown at 12 and 18, Fig. 2, 12 and 19, Fig. 4 (not shown) and at 1 and 10, Fig. 10. A composite plank may be formed by casting two of the bars in a concrete slab 6 as shown in Fig. 8.

Title: Inspection and sorting of sheet materials by photoelectric means
IPC: G01N21/894
Filed: 1966-09-15
Abstract: 1,124,778. Photo-electric detection of holes in sheet material. NASH & HARRISON Ltd. Sept.15, 1966 [Sept.23, 1965], No.41209/66, Heading G1A. Defects, such as holes in moving sheet material, e.g. in paper sheets to be sorted, are detected by illuminating one side of the sheet with radiation in a narrow wavelength band in the ultraviolet region of the spectrum, the sheet material being opaque to these wavelengths, and detecting any radiation passing through holes in the sheet, by means of photo-cells sensitive only to the same narrow wavelength band. The wavelength band chosen is in the region of 3650 Š. The lamps used are of the fluorescent type, emitting ultraviolet radiation, and are contained in a long casing 2 whose axis is at right angles to the direction of movement of sheet 1. Two elongated lamps contained in the casing 2 have their inner ends overlapping to cancel out discharge end effects which occur in the lamps. Actual reduction of the effects can be accomplished by reversing the supply polarity periodically, if they are operated on D.C. Alternatively, very high frequency A.C. supply may be used e.g. 30,000 c/s. In this case the amplifiers in the detector circuit have to have a high frequency response lower than this frequency. Adjustable shades 14 are provided to vary the extent of the radiation beam. Any radiation passing through a hole in the sheet is picked up by photo-cell units 3A, 3B mounted in inspection head 9 which may have a thin, longitudinal aperture facing the material through which light reaches the cells. Each unit comprises a pair of photo-cells, one cell of each pair being connected to amplifier 4A and the other of each pair to amplifier 4B. In this way the amplifiers operate on the difference between signals from two cells, and undesired signals due to noise, ambient light variations &c. are not amplified since they are picked up equally by each photo-cell unit. The amplifiers have integrators and feed a trigger pulse generator 5 and delay circuit 6, which enables sheet sorting to be carried out. Glass filter elements passing only the u.v. wavelength band of interest may be provided in front of each photo-cell, which itself may have a photo cathode of a sensitivity peaked at the same particular wavelength. By addition of a further opening on the other side of casing 2, a further moving sheet can be investigated by a second inspection head, Fig. 4 (not shown).

Abstract: 1,000,764. Ropeway crane. ST. EGYDER EISEN-UND STAHL-INDUSTRIE-GESELLSCHAFT. Nov. 19, 1962 [Nov. 17, 1961], No. 43701/62. Heading B8B. A ropeway crane has means which prevent the release of a cone supporting the suspension tackle when a load is being supported until the cone has been lifted to support the load directly and to take up any slack in the suspension system. A crab 35 travels on a cable 37 between stations having car hooks 17 which co-operate with crab hooks 5, Fig. 4. The crab has a coupling bell 28 and a cone 30, to which the crane rope and suspension tackle is secured, which is retained therein by members 23 and locking members 25, Fig. 2. The members 23 are engaged by retaining levers 22 connected by a linkage 18-21, Fig. 1, to levers 1, 4 constituting tripping members co-operating with the car hooks 17. When the cone 30 is raised into the bell 28 it engages a ring 32 which through the linkage 18-21 moves the levers 1, 4 so that a locking lever 15 is released, allowing the hooks 17, 5 to trip while at the same time the levers 22 engage the members 23. On arrival at a car station its hook 17 enters the crab and through a cam lever 7 trips the levers 1, 4, so that the locking lever 15 can lock the hook 5 to keep the hooks 5, 17 engaged. At the same time the lever 4 is lifted from a detent 6 so that if the core 30 is not loaded the linkage 18-21 may be moved by a spring 12 to lift the levers 22 from the retaining members 23, thus allowing the core to be lowered. If the core 30 is loaded the friction between the levers 22 and members 23 prevents movement of the linkage 18-21 by the spring 12 until the core 30 has been lifted to allow the members 23 to be moved on to steps 33 by a spring 24 and the levers 22 to be moved continuously. An alternative mounting for the members 23 is described.
