Abstract: 833,964. Tanks. SVEREMO A.B. May 23, 1958 [May 24, 1957], No. 16585/58. Class 69 (1). In a method of building liquid storage tanks above ground level, the roof 2 of the tank is built during an early stage of the wall construction and is used as a platform during subsequent constructional stages, the roof being supported by pontoons 3, 4 floating on water which is supplied to the partially completed tank and the level of which is adjusted to maintain the roof at a convenient working height as the construction of the tank proceeds. A stationary hoisting crane 5 is provided on the roof 2 near the periphery thereof for lifting and transporting plates 6 and like constructional materials, the hoisting crane being displaceable about the periphery of the tank by rotating the roof in the tank. The roof is covered by roofing plates in the regions near its periphery and centre portions. Welding machines 7 are set up at the centre of the roof. Cables 9 supplying the current to the welding machines and to the windlass 8 of the crane 5 pass through waterproof cable passages 10 in the tank 1.

Title: Improvements in thermionic valve gating circuits
IPC: H03K17/54
Filed: 1947-06-24
Abstract: 643,471. Valve relay circuits. HARDIE, A. M., and METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. June 24, 1947, No. 16657. [Class 40 (vi)] In a gating circuit, a normally conductive valve connected with its output circuit in parallel with the output of the gating valve is cut-off when the gate is opened so that the reduction in its anode current compensates for the increase in the signal current caused by the gating signal. The output of a multivibrator V1 is amplified by valve V2 and a positive pulse applied to the suppressor grid of gating valve V3 to allow the signal applied to the control grid to pass. A negative pulse taken from the cathode resistor of amplifier V2 is applied to the suppressor grid of compensating valve V4, cutting it off and thus reducing the current flowing in the common anode resistor of valves V3, V4 so that the output signal level is not changed due to the gating pulse.

Title: Improvements in or relating to processes for treating ferrous metal and alloys
IPC: C21C1/00
Filed: 1934-06-09
Abstract: Metals and alloys are treated to improve their physical characteristics by bringing them, in the molten condition, into contact with a chromate or equivalent acid oxide salt (tungstate, uranate, or molybdate) of a metal of group 2 in the periodic system and/or iron nickel or cobalt without the presence of a molten slag, the amount of chromate &c. being sufficient to burn out any oxidizable impurity present and to treat the molten metal to improve it.  The chromate &c. may be added in a plurality of doses at different times and more than one chromate &c. may be used.  The treatment of aluminium or aluminium alloys with zinc chromate, cast iron with zinc or calcium chromate and magnesium with zinc chromate or a mixture of zinc and strontium chromates is referred to.  Cast iron after treatment with zinc chromate, contains 0,4 per cent of chromium and not more than 0,05 of zinc.  One or more additional metals such as bismuth, tin, nickel, manganese, or magnesium may be added to the metal under treatment. Nickel magnesium alloys may be prepared by treating magnesium with zinc chromate and then dissolving nickel in the treated metal. Similarly, cobalt-magnesium and tungsten magnesium alloys may be prepared.  According to the second Provisional Specification, the chromates used are free from chlorides and sulphides and may be prepared as described in Specifications 422,860, [Group III], and 428,375, [Group XXXVI].  The metal to be treated may be melted in contact with the chromate &c. and the chromate &c. may be added to the molten metal in the form of a dry powder, a moist or dry paste, enclosed in a metallic or other envelope, or may be forced by air or gas under pressure into the molten metal.

Abstract: 997, 050. Measuring bridges. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 6, 1963 [May 4, 1962], No. 17234/62. Heading G1U. [Also in Divisions H1 and H3] An inductive voltage divider, used as the ratio arm of an A. C. Kelvin double bridge, comprises a number of tapped windings providing decades, some of the windings being on separate cores. Of the windings forming the eight decades shown, the first two may be on single cores and the remaining six in pairs on three common cores. The cores may comprise high-Á low-loss Ni-Fe alloy tape wound to provide a toroidal core. The windings preferably comprise ten randomly-twisted enamelled wires wound in a single layer which fills the inner circumference of the core. In order to decrease resistance, two cables connected wire for wire in parallel may be used. The ten wires are preferably made from the same single length cut into ten parts. The switching arrangement (Fig. 2) is so arranged that no section of the divider will be short-circuited, nor will the tapped voltage be open-circuited. The wipers W 1 , W 2  are of the make-before-break type whereby resistances, e.g. R 1 , R 2 , are introduced in series with the turns which are about to be cut out as the wiper moves from one set of tappings to the next. e.g. from 6 to 7.

Title: Device for deriving a frame synchronisation signal from a received binary data series flow having a given bit repetition rate a repetitive but unknown structure and a synchronisation bit in a particular time slot in each frame
IPC: H04L7/08
Filed: 1974-04-19
Abstract: 1444323 Data transmission COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 19 April 1974 [27 April 1973] 17327/74 Heading H4P In an arrangement to determine which one of several possible incoming frame lengths are presented by identifying the spacing of sync. bits in a particular slot in each frame, a search is made by setting a circuit initially at n bits per frame 8 comparing n with N, the actual number detected to ascertain whether this provides a positive result i.e. equality. If not, the n clock pulses which define a window for frame investigation are shifted by one bit relative to incoming data flow until all possible coincidences have been exhausted without equality. Pulse number n is then increased by 1, and the above operation repeated et seq. until a positive result is obtained. When p (a number set by probability) frames have been counted by divider 35 and 35<SP>1</SP> on the basis of a set n bits loaded into counter 14 and reverse counter 31 has not yet recorded j coincidences between incoming sync. bits and every nth bit produced by the circuit, flip-flop 34 currently set at 1 allows a pulse p to pass to shift circuit 11; b reverses counter 40 by 1 and repositions counter 31 to j via 32. When n successive cycles have been made, with negative result, this is taken as proof that n does not equal N. Counter 40 through gate 44 then increments counter 14 by 1 and through a delay T2, the new value is placed in counter 40 through 41. For certain value of n, j coincidences are observed for p frames which indicates that n=N hence flip-flop 34 is reset to zero by counter 31 which blocks shift pulses from 11. Flip-flop 45 is reset to zero and blocks any further adjustment of n. In a modification, to increment n more quickly in the event of a negative result, a further circuit provides a short cycle of say 5 shifts (see 51-55, 58-60, Fig. 3, not shown). For negative result in this circuit the long cycle circuit is reset but if the short cycle circuit provides a positive result the long cycle is continued to give confirmation of synchronization.

In Fig. 1 the rack 10 is carried by supports 11 secured to the carriage 2 by screws &c. 12 in the same horizontal plane as the axis of the pinion 9 of the escapement device 7 mounted on the frame 1; the supports 11 may thus be shifted if required to the broken line position in which the rack will engage the underside of the pinion. Instead of the axes of the screws 12 being parallel to the platen 3, they may be parallel to the pinion axis. In another form, Fig. 4, the rack is carried either by supports 11 or by supports 18 pivoted on the carriage at 12b and 19 and coupled by a trunnion 20 engaged in semicircular notches in their ends. A carriage release lever 13 pivoted at 14 is connected by a toggle link 15 to one of the supports 11; a spring 16 or 22 urges this lever against a stop 17 or 21 set so that the link 15 is in line with the pivot 14 to lock the rack in engagement with the pinion. The carriage, Fig. 1, runs on balls 6 located between rails 4 on the carriage and on a fixed support 5.
