Title: Safety cut-out device for use in connexion with heating, drying and like apparatus
IPC: F16K17/00
Filed: 1921-12-02
Abstract: 190,627. Keith & Blackman Co., Ltd., J., and Keith, G. Dec. 2, 1921. Safety cut-off valves, particularly adapted for use in connection with heating and drying apparatus, such as that described in Specifications 167,236 and 177,710, [both in Class 51 (ii), Furnaces and kilns for applying &c.], are adapted to close in the event of the failure of the gas or air supplies. The diaphragm valve E controlling the gas supply is loaded by a weight F of such dimensions that gas pressure acting on the valve face E<1> alone is insufficient to open the valve. The valve is opened by a spring-loaded push-rod L engaging the valve spindle J<1> when gas pressure acting on the diaphragm E retains the valve open. The air pressure enters at K and acts in a second diaphragm G loaded by weights H which load, in the event of a failure of the air supply, is transferred to the diaphragm by a spindle J to close the valve E<1>.

Abstract: 324,974. Cockburn, D. Nov. 7, 1928. Yarns, treating with liquids.-Threads or yarns of cotton, wool, or other fibrous materials are impregnated with a solution of viscose or other cellulose derivative by passing the thread through a valve chamber, the aperture of which can be varied according to the thickness of the thread or yarn, into an impregnating chamber containing the solution, through the chamber and through an outlet valve with an adjustable aperture, the solution being coagulated on the thread immediately on leaving the outlet. The apparatus comprises a chamber A, Fig. 1, into which the solution is admitted by a pipe B<1>. The yarn enters through a pipe H and a valve chamber D. The adjustable valve comprises two plates E, F, Figs. 1 and 2, sliding in a bored. The plate E is of cylindrical shape with flanges e entering recesses in the valve body, and is slotted to receive the plate F. Both plates are formed with T-slots at their rear ends to receive the ends of adjusting screws G. Grooves E', F<1>, Fig. 3, of V-shape are formed in the end faces of the plates E, F and form the adjustable opening. The yarn or thread entering through the pipe H, Fig. 2, passes round a grooved pulley K to the outlet pipe L, Fig. 1, which is preferably disposed at an angle of about 25‹ to the pipe H. Thence it passes out through a second valve M of the same construction as the inlet valve into a coagulating bath, in which the whole apparatus with the exception of the inlet valve may be submerged. The apparatus may be made of acid resisting alloy, or partly of metal and partly of glass or porcelain. The impregnating solution is under pressure.

Patent GB-1023413-A (GB)
Title: Degassing of metal or alloys
IPC: C21C7/10
Filed: 1964-08-11
Abstract: Molten metal is elevated through a barometric inlet leg into a vacuum chamber wherein it is subjected to turbulence and cascading action by causing it to flow down a sloping irregular surface before leaving the the chamber through a barometric outlet leg. The apparatus may be so arranged that the metal on leaving the sloping surface falls in drops or a film into the outlet leg. Inert gas may be admitted to the inlet and/or outlet legs, and the process may be operated continuously. Degassing of low carbon steel may be facilitated by the introduction of finely divided carbon into the metal leaving the inlet leg.

Title: Improvements in or relating to methods of soldering conductors to semi-conducting elements
Inventor: TAYLOR ERIC WILFRED
IPC: H01L21/00
Filed: 1958-10-14
Abstract: 929,828. Semi-conductor devices. ELECTRIC & MUSICAL INDUSTRIES Ltd. Sept. 28, 1959 [Oct. 14, 1958], No. 32755/58. Class 37. A method of soldering a pair of conductors to a semi-conductive element comprises applying the conductors to the element with solder therebetween and passing an electric current through the element to beat it so as to melt the solder and provide a non-rectifying connection to each conductor. The solder may be applied to the semiconductive element or to the conductors or to both. The solder used may be a soft solder, e.g. eutectic solder with about 40% Sb, 60% Su, 2% Sb or 95% Su, 5% Sb or a hard brazing solder and may have a flux or fluxes e.g. ZuCl 2  in water or " Tricene " (Registered Trade Mark). In the drawing, 1 is a crystal of N-type germanium, Si, or indium arsenide exhibiting the Hall effect, current being passed in direction A between input conductors 3, 4, and current or voltage being derived in direction B by output conductors 8, 9, and a magnetic field applied by an electromagnet perpendicular to the plane of the drawing. The conductors may be strip, circular or plate conductors of tinned copper. The crystal 1 has layers of solder for 3, 4 and localised portions of solder for 8, 9 spaced from the layers of solder. Crystal 1 is mounted on support 2, 3, 4 are held taut and terminals 5 fixed in position and connected to the secondary of a transformer, or to a D.C. source. Connectors 6 which may be of insulating or conductive material are slidably mounted on fixed rod 7; they are moved away from each other to allow 1 to be mounted on 2 then moved towards each other to allow 3, 4 to engage the surfaces of 1 having the solder layers thereon. Current is now passed through 3, 4 to melt the solder and solder 3, 4, 8, 9 to 1. The decrease of resistivity of 1 with rising temperature can be used for automatically stopping the current to element 1 by operating a relay (when the current rises to a predetermined value). The device may operate as a voltage multiplier. To reduce the coupling between the magnetic field and conductors 8, 9, 8 or 9 may be formed as a double lead e.g. a hairpin, the apex being soldered to element 1 and each limb being bent to form a loop surrounding 1. Both 8, 9 may be hairpins. One limb of each hairpin can be severed near the apex. After the soldering all exposed areas are coated with an opaque insulating varnish.

Title: Improvements in automatic devices for maintaining a constant electrical pressure on line voltage
IPC: H02P9/24
Filed: 1928-11-12
Abstract: 327,947. Whipp & Bourne, Ltd., and Whipp, F. Nov. 12, 1928. Regulation, automatic.-Apparatus for ensuring constancy of line boltage by varying resistance in the field circuit of a generator comprises a stepby-step rheostat switch operated by two solenoids, alternatively energized through the operation of a voltage-responsive relay, and two switches, one to short circuit and the other to insert a considerable portion of the field resistance upon the operation of the governing relay, to accelerate the regulation. In the form shown in Fig. 1, the voltage relay 2 on low volts energizes solenoids 6, 8. The latter immediately closes contacts 9 to short circuit all the resistance 1 in the field circuit and is shunted by a resistance 20 to delay its de-energization. On high volts relay 2 energizes solenoids 5, 10. The latter at once inserts at contacts 11 all the resistance 1 into the field circuit, it is also shunted by a resistance. Meanwhile the solenoid' 6 or 5 is intermittingly energized by the action of contacts 7, opened by each solenoid at the end of its stroke, so as to gradually vary the resistance in the field circuit in the required sense. A modification, shown in Fig. 2, ensures that the solenoids 8, 10 shall always control the same amount of resistance. Contact-arms 13 - - 15 are moved as one by the solenoids 5, 6. The contacts 9, 11 may be operated by the solenoids 6, 5 respectively.
