Title: Improvements in or relating to apparatus and method for melting metal
IPC: C21C5/56
Filed: 1938-08-09
Abstract: 517,873. Preheating and melting metals. BUDD WHEEL CO. Aug. 9, 1938, No. 23466. Convention date, Aug. 9, 1937. [Class 51. (ii)] [Also in Group XI] Finely divided metal such as cast iron borings containing combustible foreign matter is fed through a preheater to drive off the foreign matter and is fed through the preheater to a bath of molten metal in a furnace at such a rate that it is melted substantially as it enters the bath. As shown in Fig. 1, the metal is fed from a hopper 24 having an adjustable slide 26 on to a vibrating trough 16 arranged within a preheating chamber 14 where it is subjected to the flame from a burner 29. The metal falls from the trough 16 down a shoot 32 into a hopper 33 provided with an outlet controlled by a slide so as to feed the metal into the hopper 37 of an oscillating electric furnace 10 when the hopper 37 arrives beneath the hopper 33. The slide is actuated by a motor 36<1> controlled through a slide valve 37<1> operated by a cam on the wall of the furnace 10. In the furnace 41 shown in Fig. 4, the' metal is fed to the centre of the bath 43 between the electrodes by a refractory shoot 42. Material such as graphite, coke or the like or silicon may be added to the metal in the preheating chamber.

Abstract: 864,378. Fluid-pressure brakes. WESTINGHOUSE AIR BRAKE CO. July 23, 1957 [July 27, 1956], No. 23572/57. Class 103 (1). A compressed fluid braking apparatus of the graduated release kind comprises a control reservoir 3 charged from brake pipe 2 through a fast charging communication including passage 34, valve 95, choke 97, passage 98, bore 99 of valve 52, passage 100, chamber 46 in valve 45 and passage 16, and a slow - charging communication via a branch of passage 34, chamber 32 of valve 25, passage 33, past valve 68, passage 71, choke 103, passage 100, chamber 46 and passage 16, the valve 52 closing when control reservoir pressure acting in chamber 49 reaches a predetermined value, the valve 68 being associated with a quick service valve means 11 which, in response to a slight reduction in brake pipe pressure, closes the slow charging communication in addition to locally further reducing the brake pipe pressure, the valve 45 closing secondarily, the slow charging communication while the brakes are applied; an auxiliary reservoir 4, for supplying compressed fluid to at least one brake cylinder 5, is also charged through separate fast and slow communications. A valve 101 closes the auxiliary reservoir fast charging communication when pressure reaches a predetermined value and valves 68 and 45 both close the slow charging communication as for the control reservoir slow charging communication. The pressures in the control and auxiliary reservoirs 3, 4 equalizing with brake pipe pressure via the slow charging communications. A reduction ensuring valve means 12 controls the communication of a quick service volume 77 to atmosphere via passages &c. 76, 46, 94 and 93, the valve 82 closing the communication to port 93 in response to brake cylinder pressure in chamber 87 and control reservoir pressure in chamber 80 acting on diaphragms 86, 78, respectively, overcomes springs 88, 89 and the reduced 'brake pipe pressure in chamber 81. Reduction in brake pipe pressure acting in chamber 67 allows valve 68 to be moved by auxiliary reservoir pressure in chamber 66 to close passage 71 and then passage 70 from passage 33 and pipe 2, the pipe 2 being locally vented via passages &c. 34, 67, 72, 76 and volume 77. The brake pipe pressure in chamber 17 of service valve 7 allows control pressure in chamber 15 to raise valve 25 and poppet valve 37 to pressurize the brake cylinder from auxiliary reservoir 4 via passages &c. 39, 38, 37, 27 and 22, the valve 7 eventually being returned to a lap position by brake cylinder pressure in chamber 21. Brake cylinder pressure acts via passages &c. 22, 90, 91, in chamber 42 of valve 8 to shift valve 45 to close the slow-charging communication, and acts in chamber 87 of valve device 12 to move valve 82 to cut off the venting passage of volume 77. An increase in brake pipe pressure causes valve 7 to close valve 27 and release fluid from brake cylinder 5 via passages &c. 22, 27, 28, 29, 35 and choke 36. Specification 803,685 is referred to.

The shaft 18 is connected to a steam supply and is rotated by a unit 30 comprising two motors 68, 70. The drum 20 is internally divided by a diametral partition 38 with spraying nozzles 24 supplied from shaft 18. The container 12 has a steam-heated casing 66 on its lower part. Articles are loaded through a hatch 14 and a flap in the drum 20. Motor 68 operates, changing the sense of rotation of shaft 18 every few revolutions, while washing liquid is sprayed from nozzles 42. Used liquid is drawn off through openings 48 into duets 50. Blades 22 on the end faces of the drum 20 agitate the liquid. Rinsing and any further treatment is then performed, appropriate fluids being dispensed by the feeding arrangement 46 to the nozzles 42. Motor 70 then accelerates the drum by a steplessly variable hydraulic drive 74. The articles, held by centrifugal force, are distributed over the wall of the drum 20. Superheated steam at a pressure automatically maintained by a valve 76 is introduced into the drum 20 through nozzles 24 and subsequently sterile air for drying the articles is supplied by a blower 58 through a filter 56 and ducts 52, 54, and is drawn off through opening 60 by a fan 62. Finally the machine is emptied through hatch 16. Hatches 14, 15 may be completely separated by building the machine into a partition. During loading blower 58 operates to maintain a sterile atmosphere in the machine and during unloading fan 62 maintains a flow of sterile air through the machine. Means for preventing hatches 14, 16 being open together may be provided. The machine may be controlled by a preset programmer.

Electromagnetic relays; protective arrangements.- A wattmeter relay suitable for use in a differential protective system and acting in accordance with the sum or difference in the power in two circuits of continuous or alternating current has a magnetic system common to the windings P', P<2> and P<1>1, P1<SP>2> of the two circuits concerned and a movable system comprising two separate voltage windings S, Sand S', S<1> so placed, as shown, in relation to the corresponding magnet poles that there is no action of one circuit on the other such as would give an additional couple. The rectangular-shaped windings S, S and S<1>, S<1> are traversed by current proportional to the voltage of the supply to the windpings P\, P<1>2 and P', P<2> respectiely. The composite movable armature system is controlled by a spiral spring R and a fixed core N is employed. The axis of the movable system is secured to a switch-lever B which is moved through a slight angle to bridge contacts G1, G2 in a tripping circuit. The tripping circuit includes an electromagnet E which is energized to maintain the switch lever in the displaced position. The lever normally rests, under the action of the spring R, in engagement with an adjustable spring plate L provided to damp vibrations. Adjustments for current or power setting are made by varying the tension of the spring R. As applied to the differential protection of a rotary converter, Fig. 3, the pole windings P', P<2> are supplied from the alternating current side through the current transformer T<1> and the pole windings P<1>, P<2> from a resistance shunt B<1> in the direct current side. The two coils of the armature system are supplied by voltage connections to the two sides through three rings, one common to both sides, and flexible connections, resistances being inserted in the circuits.

Title: Improvements in or relating to production of phonograph records
Filed: 1931-08-27
Abstract: Stamping dies for gramophone records are made by recording the sound impressions on a thick wax plate and forming a negative matrix by electrodeposition of copper thereon, stripping and nickel plating the copper and backing it with sheet copper.  A cellulose acetate or like thermoplastic blank then is moulded by heat and pressure against the copper matrix to form a second positive matrix, which is again treated by a similar electrodeposition process to form the stamping dies.  In forming the cellulose acetate matrix a pressure of one ton per square inch is used at a temperature of 370 DEG  F.  To metallize the surfaces of the wax and cellulose acetate matrices to promote the electric deposition of the copper a film of molten metal, for example gold or silver, is sputtered on to the surface.  Specification 378,355, [Group XXXVI], is referred to.
