Title: Improvements in the heat treatment of rail weldings
IPC: C21D9/50
Filed: 1937-04-22
Abstract: 494,175. Heat-treating rails. BAL, M. J. April 22, 1937, No. 11565. Convention date, April 22,1936. [Class 72] In the heat-treatment of a rail weld, the joint and regions on either side of the weld are annealed and then cooled by sprinkling with cooling fluid adjacent sections of these regions separately and successively from the outermost coldest sections towards, and including, the joint, the fluid being applied when the respective sections reach the optimum temperature for hardening or cooling. The sections symmetrically disposed about the joint are treated simultaneously. A container is provided with compartments 1, 2, 3, 4, 5 each having a filling opening 9, the container being turned upside down for filling, and a perforated bottom. The end plates 6, 7 of the container are saddled above the rail and the upper part of each compartment is provided with a tube 10 having a valve 11 which can be opened or closed so as to cause water to flow through the perforated bottom of the compartment or the flow of water to stop. Tubes 10 from symmetrical compartments may be connected so that one valve 11 is used for both such tubes. A flexible sheet 12 fixed to a bar 13 extending between the plates 6, 7 is placed so that its free end is pressed elastically on to the rail head, so as to discharge the water laterally away from the base of the rail.

Abstract: 946, 512. Signal-controlled tape recorders. SANDERS ASSOCIATES Inc. March 27,1962, No. 11593/62. Heading G5R. A tape recorder arranged with interengaging components mounted on spool carriers 10,11, has slow forward and rapid reverse capstans 49,17 with a head 13 and pressure pad 48 between, solenoid means, activated by the input signal, rocking a member 14 to engage a pinch-roller 56, the input signal also proceeding via a delay network to the head 13, such that the tape has time to accelerate from rest before recording the signal completely from its start. The capstans 49,17 also drive spools in the carriers 10,11 by slipping belt means, the pad 48 engaging the tape sufficiently to prevent tape drift during 'standby' when pinchrollers 54, 56 are disengaged. The capstan 17 may provide either fast rewind or fast playback. To assist tape acceleration, the tape is led over sprung rollers 39, 41, mounted on a carriage 42 sliding in a housing 12. For battery economy, the 'start' solenoid is double-wound, comprising low impedance 'activate' and high impedance 'hold' windings.

Abstract: 513,751. Propelling aircraft. TENNANT, W. J. (Aktiebolaget Milo). April 19, 1938, No. 11777. [Class 4] Aircraft power-plant includes an internal combustion engine. 11, the exhaust gases from which drive a mechanically-independent turbine 14 arranged to drive at least one air compressor 17 and the exhaust from which is utilized to produce a propulsive reaction-effect. In one form, the exhaust gases pass from a manifold 13 to the turbine arranged in the cowling 15. The turbine drives, in addition to the compressor 17, an auxiliary airscrew 18 adapted to rotate in a direction opposite to that of the main airscrew 12. Air is drawn from the front and supplied, to supercharge the engine, through' a conduit 21. A conduit 22 provided with a valve 23 provides means whereby compressed air may, under the control of the pilot, be supplied to cool the exhaust. The output of the turbine, which is provided with a discharge pipe 19, may be controlled by a pipe 25 and valve 26 connected to the pipe 19. The pipe 25 may communicate with the turbine inlet. In a modification, the turbine outlet is connected through an adjustable valve with output from the compressor. In a further modification the exhaust may be discharged past an adjustable valve direct to the atmosphere and in a further form a portion of the exhaust may be bye-passed to the pipe 19. When more than one compressor, is provided one or more of the compressors may be driven by the engine and one or more by the turbine.

Title: Power supply arrangements
IPC: H02M1/10
Filed: 1974-03-18
Abstract: 1460756 Rectifying BRAUN AG 18 March 1974 [17 Sept 1973] 11837/74 Heading H2F A circuit for supplying a D.C. consumer device from mains A.C. comprises a voltage doubling capacitor 82, diodes 70-72, a thyristor 83 and a voltage sensor 3 which connects the cathode of the thyristor to its control electrode 830 when the mains voltage exceeds a threshold value and connects the control electrode to the mains terminal N 1  when the mains voltage does not exceed the threshold value. The consumer device is connected across output terminals V 1 , V 2  in parallel with a consumer device capacitor 81. When 220 volts A.C. is applied to the terminals N 1 , N 2  a transistor 30 in the sensor 3 is switched on and prevents triggering of the thyristor 83. The capacitor 81 is therefore charged with the rectified mains voltage via the diodes 71, 72. If 110 volts A.C. is applied to the terminals N 1 , N 2  the transistor 30 is non- conductive and the thyristor is triggered via a Zener diode 32. The voltage across the capacitor 82 is added to the mains voltage to double the voltage applied to the consumer device. In a modification two of the supply circuits are connected in parallel to supply a voltage with reduced ripple at the D.C. output terminals.

Abstract: 474,422. Reinforced concrete. GRIFFEL, H. April 28, 1936, No. 12097. Convention date, Dec. 14, 1935. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 22, 1937.] [Class 20 (iv)] A non-circular reinforcing member for reinforced concrete structures is made of steel having a high yield point, and the cross-section thereof is derived from the cross-section of a normal circular iron reinforcing member of diameter d, and is produced by removing from the circle two opposite lens-like segments by arcs having the same radius as, or a smaller radius than, the circle. The resultant crosssection has an area which is smaller in the desired proportion to the area of the complete circle, but has a periphery which is greater than or equal thereto, whereby the non-circular steel reinforcing member is adaptable for higher allowable stresses and is exchangeable directly for the circular iron reinforcing member, that is without any further calculation or alteration of plan. In the construction shown, the concave portions y each extend through an angle B=87‹14' and each has a radius r<1> which is equal to the radius r of the circle. In a modification, the edges between the concave and convex parts are rounded off. In another modification, ribs bridging the concave portions, are arranged at spaced intervals along the bar, and according to a further construction, the bar is twisted around its longitudinal axis. The Specification as open to inspection under Sect. 91 describes also a number of other reinforcing bars of non-circular cross-section. According to one construction, the bar is of elliptical cross-section and in other constructions the bars are substantially rectangular in section and have rounded corners or rounded ends. In another construction, Fig. 6 (Cancelled), the cross-section of the bar is derived from a circle of diameter d and comprises five convex portions of radius r which merge into five concave portions of radius r<1> ; other similar bars are described which differ only in the number of the concave and convex portions. This subject-matter does not appear in the Specification as accepted.

Title: Process of treating lead ores
IPC: C22B13/00
Filed: 1954-04-27
Abstract: Rich lead sulphide materials are smelted in admixture with soda and carbon and if desired, iron oxide, in a rotary reverberatory furnace at a temperature between 700 DEG  and 1000 DEG C. thereby retaining the lead in the furnace as molten metal.  The iron oxide may be added in a maximum amount of approximately 200 per cent of the soda content of the charge and up to 10 per cent of the soda may be replaced by sodium chloride or sodium sulphate.  The method allows separation of lead from some of its accompanying metals since copper and arsenic together with the major proportion of bismuth go into the sulphide phase; antimony and the noble metals remain with the lead and may be separated therefrom by the usual refining methods.  The raw materials are preferably granulated to a grain size of 3-10 m.m. by wetting with water at 50 DEG -70 DEG C., before charging into the furnace, said furnace advantageously being one rotating about a horizontal axis and with its interior length not greater than its internal diameter.  Reference has been directed by the Comptroller to Specification 713,177.
