Title: Method of cooling steel poured into an oscillating open-ended  mould and apparatus for performing the method
IPC: B22D11/049
Filed: 1972-10-03
Abstract: 1385555 Continuous casting CONCAST AG 3 Oct 1972 [5 Oct 1971] 45634/72 Heading B3F A solidified shell of a continuous casting is formed in a first mould part 2, e.g. of copper, in which the casting is indirectly cooled and from which the casting passes into a second part 3 of the oscillating mould 1 where coolant is sprayed directly on to the shell of the casting from a number of nozzles 4 as it is guided by supporting surfaces 6, e.g. of iron-carbon alloy, in positions which precede and follow each nozzle 4 and are kept free from sprayed coolant, the water being conducted away rearwardly, e.g. by sloping surfaces 16 of plates 5 which provide a grid of supporting surfaces 6. The mould 1 may be arcuate. The cross-sections of the parts 2 and 3 of the mould 1 are adjustable independently. The upper detachable part 2 may have parallel or slightly tapered walls but the lower part 3, adjusted by screws 9, 11 may have a greater taper. Slim fan-jets 22 of coolant extend across the casting direction at the entrance to the second part 3. In the lower openings 15 between the faces 6 a narrow strip 17 at the bottom is free of the spray so that scale rubbed off by the faces is washed away without hindrance. The plates 5 may have internal cooling ducts. The openings 15 may be round, elliptical or hexagonal. Temperature-responsive elements 24, 27 behind the faces of the mould parts 2 and 3 indicate whether the plates 5 need resetting by the screws 9, 11 and whether readjustment is necessary because of the appearance of a shrinkage gap.  Specification 1,354,758 is referred to.

In order to increase the flux to which the movable magnetic reed contact 6 is subjected without increasing the dimensions and hence the rigidity of the reed a stationary extension 7 magnetically in parallel with the reed is provided. The reed 6 co-operates with a fixed magnetic contact 3 surrounded by an energizing coil 4 and the end 6a opposite the fixed contact is enlarged so that it will carry the flux from the extension 7 as well as the flux through itself. A barium ferrite magnet 2 with polepieces 1, 1<SP>1</SP> is arranged to hold the reed in engagement with the fixed contact until a pulse of the opposite polarity to the closing pulse is applied to coil 4. The extension 7 also acts as a backstop. The entire structure is enclosed in a container 9.

Abstract: 947,825. Thermo-electric devices. WESTINGHOUSE ELECTRIC CORPORATION. Dec. 27, 1961 [Feb. 6, 1961], No. 46311/61. Heading H1K. A tubular thermo-electric device consists of a plurality of thermo-electrio elements which each comprise a hollow cylinder of thermoelectric material in direct contact with an outer tubular conductive member and an inner tubular or rod-like conductive member, and which are electrically and mechanically connected together in axial alignment by a plurality of annular couplings interposed between them, each coupling electrically connecting only one conductive member of an element to only one conductive member of an adjacent element and thereby connecting the elements in series so that current passes through the thermoelectric material of each element from one of its conductive members to the other. It is stated that while, as in the embodiments described, the material of an element may be of N-type or P-type, it is possible in a single element to provide concentric rings of a plurality of materials. The N-type (using, e.g. lead telluride) and P-type (using e.g. zinc antimonide) elements may be made from metals and the appropriate thermo-electric material by any suitable process such as casting, swaging, or compression, or by an extrusion process. Fig. 1 shows the part of a device where connection is made between two elements of opposite polarity, the annular coupling being composed of an alumina ring 28 of T-shaped cross-section and a conductive ring 30. The alumina ring may be partially metallized as shown at 32 to facilitate brazing to the extended ends of the conductive members of the elements. Electrical connection between adjacent elements is made by ring 30 whose end faces may be pre-coated with solder to facilitate connection. Alternatively, the ring may be formed by introducing solder and allowing it to solidify in situ. At the other end of the element the positions of the insulating and conducting rings are transposed so that electrical connection is made between the outer conductive members of adjacent elements. At the ends of the device, Fig. 3 (not shown), insulating washers seal in the thermo-electric material and connections are attached to take current off generated by the passage of hot fluids through the central duct of the device. It is sometimes desirable to connect two elements of like polarity in series and as shown in Fig. 4, a conductive member 82 of cranked cross-section may be brazed or threaded to conductive members of adjacent elements. Insulating washers 78, 80 are used to hermetically seal the thermo-electric material.

Title: A Method of and Apparatus for Detecting Traffic Delay

Filed: 1967-10-12
Abstract: 1,192,025. Road traffic measurements. TATEISI ELECTRONICS CO. 12 Oct., 1967 [20 Oct., 1966], No. 46685/67. Heading G4Q. Traffic congestion is measured by determining the time spent by vehicles in a detection zone, e.g. of an inductive loop detector. The time that a vehicle spends in a detection zone depends on its length and on the length of the detection zone; the total detection time in a given period gives an output equal to the sum of two terms, one proportional to traffic density and the other to average time occupancy, and this is used as a measure of congestion. In Fig. 3, five detectors in five traffic lanes are coupled to terminals 25- 29 so that pulses from a clock pulse generator 22 pass from various stages of a divider 24 to the output gate 38 for as long as any detector is actuated. The output pulses are divided by a counter 40-42, the division ratio of which is variable by the range control switch 47, and by a further divider 30. Divider 30 is set in accordance with the number of detectors used, and with five detectors would divide by five. The output of divider 30 is fed to a classifying circuit comprising counters 72-74 and their associated pinboards; with the latter set as shown the bistables 90-92 are set when the count exceeds 50, 100 and 150 respectively thereby classifying the output in four ranges. At the end of a counting cycle a pulse on line 94 re-sets the counters 72-74 and allows the bi-stables 90-92 to set the output bi-stables 96-98 into the corresponding states, and shortly afterwards a pulse on terminal 100 re-sets the bi-stables 90-92.
