Title: Improvements in acid pickling tanks more particularly for steel strip mills
IPC: C25F1/06
Filed: 1946-06-11
Abstract: 613,228. Electrolytic pickling. SWINDIN, N. June 11, 1946, No. 17445. [Class 41] Steel strip is pickled by passage through an acid bath between electrodes connected to a source of alternating current. In the apparatus shown, the strip enters through a gas trap 9 in the domed roof 3, passes under rollers 11 and leaves by a gas-trap 9a. The roof 3 encloses the tank, minimizing heat loss but permitting escape of gases. The electrodes 6, 6a are supported above and below the strip by vertical insulated members at each end, one of which passes through an insulated opening 4 in the dome for connection to a bus-bar. Current density of about 100 amps./sq. ft. at 12-50 volts and frequency 80-100 cycles is employed. The bath may be dilute sulphuric acid of 12-15 per cent with or without hydrochloric acid up to 3 per cent and may be heated. When the strip is heavily scaled it may be first treated in the sulphuric acid bath and then in a hydrochloric acid bath. The baths may be arranged in a series. The strip passes from the acid treatment tanks to neutralizing and cleaning tanks. It is stated in the Provisional Specification that ferrous sulphate may be recovered from the first bath.

[Also in Divisions G2 and G3] In a film-strip driving mechanism designed to compensate for shrinkage in films with or without a sound track two spring-loaded idle rollers 16, 17 urge the film F into contact with a continuously driven sprocket 15 rotating at constant angular velocity with two raised surfaces 61, 62 which frictionally engage the film F and teeth 63 which enter the film perforations. The film is able to ride up the driving tooth 63, when shrinkage has occurred and slip relative to surfaces 61, 62 until the leading edge of the next perforation is engaged by the next tooth. Sprocket (15) is driven, Fig. 5 (not shown), on its shaft (33) by motor (22) through gears (24, 25, 28, 29) and worm (31).

Abstract: 561,682. Enamels and glazes. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 14, 1942, No. 17731. Convention date, Dec. 24,1941. [Class 56] [Also in Group XXXVI] Oxidizable metals are sealed to vitreous materials having a lower melting point by fusing to the metal a continuous adherent coating of the boric oxide and applying the softened vitreous material to the coated area. The metals include tungsten, molybdenum, and their alloys as well as iron, nickel and copper. The coating may be effected by heating the metal in an atmosphere containing boric oxide, boric acid or glyceryl borate or in a flame containing boric oxide vapour ; such a flame may be produced from a solution of boric oxide in ethyl alcohol. The thickness of the coating should preferably be between .00002 and .0005 inch, with .002 inch as the maximum. The Specification as open to inspection under Sect. 91 states that the boric oxide coating may be used to protect metals against oxidation when hot. This subject-matter does not appear in the Specification as accepted.

[Class 61 (ii).] An adjustable templet for determining the angular shape of voussoirs, such as L<1>, G, G<1>, Fig. 3, comprises two straight edges A, B, Fig. 1, connected together by swivel nuts C, C<1> and right and left screws D with graduated heads D<1> to enable the straight edges to be set to the angle of the taper of the voussoirs, pivoted links E, E<1> with a clamping bolt E<4> being provided for clamping the straight edges in set position. The templet is used as shown in Fig. 4 for setting side members F<1> of a box F so that the top edges of the sides F provide a saw guide for sawing the voussoirs clamped in the box to the required taper. The templet is also employed in conjunction with an adjustable cross-arms device K, J for cutting the end bevels of the voussoirs. The arms K, J are set and clamped to angle #, Fig. 7, and placed against edge B with arm K bearing against a fixed pin H, Fig. 8, and the reading noted on a scale I on edge A, which scale has its index point opposite pin H. The arms are then transferred to straight-edge A, Fig. 9, arm K being set whilst still clamped to the previous reading on scale I ; arm K is then released and moved into contact with pin H, angle # giving the bevel angle for voussoirs G, G<1>. Angles # are set off on base of holder N, N<1>, N<2>, Fig. 10, and the voussoirs held therein are sawn off along the lines Z, Z, Z<1>, Z<1>. This process is repeated for determining the bevels of all the voussoirs.

Filed: 1917-12-08
Abstract: 121,327. Kerr, A. Dec. 8, 1917. Track apparatus actuating signals on trains and for stopping trains. - Signals are operated or the brakes are partly or fully applied by pneumatic apparatus controlled by a lever carried bv the train and movable from the normal position either up or down in a vertical plane by a track contact member controlled by the signals. Duplicate train contacts are provided for forward and reverse running and are put in and out of action by pneumatic cylinders the supply to which is controlled by a valve operated by the reversing-lever. Fig. 3 shows a track contact apparatus for use at a distant signal. The ramp 2 is pivoted and connected by a wire 4 to the signal and is set so as to guide the train contact which passes through the entrance gates 2<c>, upwards if the signal is at danger, and downwards if the signal is clear. The ramp a,t a home signal is arranged to displace the train contact upwards to a greater extent than at the distant signal. As a preliminary warning, a fixed ramp may be used to move the train contact downwards. The ramps are supported on brackets bolted to the sleepers. Fig. 5 shows the control valves operated by the train contact member 5 which is carried by a .spindle 6, shown in Fig. 7 as a piston-rod attached to a piston 7, by which it is moved into and out of active position according to the position of a valve 21 which is moved by the reversing-lever 21k engaging the sector 21<c> on the valve spindle as it passes its neutral position. The cylinder in which the piston 7 moves is connected to relay cylinders 27 the pistons of which are connected to the whistle lever 23, and this arrangement is such that the whistle is sounded unless the piston 7 and the train contact 5 are either in the operative or inoperative end-positions. A crank 8 on the spindle 6 abuts the ends of piston valves 9, 10, and at a, clear signal the spindle is rocked so as to unseat the valve 9 and open the pipe 9<c> to atmosphere and cause the piston 12<c>, which is normally subject to the pressure of the vacuum chamber 22a on both sides, to pull downwards the whistle lever 23. A leaking ball valve 34 ensures the slow return of the piston 9 under the action of its spring. At a distant danger signal, the valve 10 is moved to open the pipe 29 to atmosphere and thereby the double beat relay valve 14<b> is caused to open the brake pipe to exhaust. The valve 14b is held open by a manually-reset catch 16. At a danger home signal, the valve 10 is moved further and carries with it the valve 11 which opens the pipe 11<b> to atmosphere, thereby causing another double-beat relay valve to open the brake-pipe to atmosphere at its full bore. The train contactarm 5, spindle 6, and valves 9, 10 are hollow and are connected to the pipe 29, so that if any of these parts break, the valve 14<b> causes an application of the brakes.
