Title: Cooling means for metal vapour rectifiers
IPC: H01J13/32
Filed: 1933-10-30
Abstract: 414,552. Metallic - vapour rectifiers. ENGLISH ELECTRIC CO., Ltd., 28, Kingsway, London. Oct. 30, 1933, No. 30144. Convention date, Oct. 29, 1932. [Class 39 (i).] A metal-vapour rectifier is provided with a closed circulating system for cooling one part thereof and with means for passing air over some part of the system and over another part of the rectifier which is cooled solely by air. Independent circulating cooling systems 2, 3, 4, Fig. 1, cooled by air 1, are provided respectively for the cathode 5, mercury-vapour evacuating pump 6 and the rectifier container 7. The air is adapted to cool directly the anodes 8. Different cooling media, such as acetaldehyde, an ethylamine, or an aromatic hydrocarbon, e.g. toluene, may be used in the various systems, and oil is used for cooling the container. In a modification, the air 1, Fig. 2, is adapted to cool the system 9 which is provided for the container 7 and is in heat exchange relationship with the system 10, which is provided for the cathode 5, pump 6 and the annular coolers within the rectifier and comprises a refrigerating machine, condenser 11 and expansion chamber 12. In a further modification, a main circulating system is provided for the container from which medium is adapted to circulate through the refrigerator, the coolers for the cathode and pump and through the annular coolers. The refrigerator may be controlled thermostatically in dependence upon the temperature of the air or by means responsive to the load. Heated cooling medium may be used to heat relatively cold parts of the rectifier or to heat a vehicle when the plant is mounted thereon. The temperature of the upper part of the container and of the anodes may be higher than that of other parts. To facilitate starting, the rectifier may be heated by changing the external connections of the refrigerator so that the circulating fluid is brought into contact with the warmer side thereof.

Title: Press for cutting out leather or similar material
IPC: C14B5/00
Filed: 1928-10-19
Abstract: 313,392. Jackson, L. Mellersh-, (Reece Shoe Machinery Co.). Oct. 19, 1928. Cutting-out presses. - In a radial-arm press for cutting leather &c. the swinging arm 116 is built up of a lower member of light metal with a high tensile strength such as an aluminium alloy, and an upper member of heavy metal with a high compressive strength such as cast iron. The members contact along a surface near the neutral axis of the arm. In Fig. 1 the aluminium member is shown mottled and the neutral axis by the lines x x, y y. The members are ribbed and are bolted together at contacting surfaces between which the parts are carved away to maintain the material away from the neutral axis. The compression member is made of smaller section than the tension member. Contacting surfaces shown not bolted allow of sliding between the parts. To facilitate manufacture the line y y is at right angles to the line x, x. In the press shown the arm swings about a post 18 and is reciprocated from a pulley 30 through a one revolution clutch. Specification 146,403 is referred to.

Filed: 1923-12-03
Abstract: 210,402. Loisy, M. C. J. E. de, and Grauce, E. Jan. 27, 1923, [Convention date]. Carbonizing processes.-Solid materials such as coal, lignite, shale, or wood are distilled by the passage of a heated current of gas therethrough the temperature of which is controlled by the addition of water, steam or a cold gas. A portion of the gas obtained is burnt with air in a furnace K and led to a chamber L where cold gas or water is added the amount of which may be regulated by a device R governed by a temperature control T. The heating gas at a temperature of about 480‹ C. passes through the cylinder A containing the material and the gas and distillates are passed through a condenser F, tar extractor G and washer H to he gasometer I. The gas may be heated by passage through a heated coil thus avoiding the admixture with combustion products, the hot gas saturated with vapour of light oils being reintroduced into the material.

A cold cathode glow discharge device includes a hollow cathode 4 having a portion in the form of a hollow sphere truncated by two parallel planes symmetrically disposed with respect to the centre of the sphere, and a perforated shielding electrode 5 of a similar shape to, and surrounding, the cathode; in operation, the shielding electrode is held at anode potential, and the shielding electrode/cathode spacing is such that substantially no discharge occurs therebetween, but streams of electrons converge on the geometrical centre of the cathode. As shown, the anode is constituted by aluminium end plates 2, 3; the shielding electrode 5 is of stainless steel wire mesh; and a filling of hydrogen at 0À5 torr is maintained by adjustment of the valve 13 and the pump 10; and the cathode may be preheated to about 200 C. by focused radiant heat or by an attached resistance heater, to avoid a glow to arc transition during the initial stages of operation. The device may be employed for heat treatment, welding, melting, or zone refinement of refractory material positioned at the centre of the cathode, e.g. a tungsten rod may be zone refined by being passed longitudinally through the cathode by means of a holder operable from outside the envelope. If preheating or gradual cooling of the material is required, cylindrical or conical extensions to the top or bottom of the cathode and the shielding electrode may be provided.

[Class 110 (i).] Apparatus for controlling a compressed-air waterreservoir is immersed in oil in a casing 10. The apparatus comprises an electric driving motor for the pump, a pressure responsive switch 33 for controlling the motor and a lightning protecting contact 1, 2. The reservoir is replenished with air and water by the pump 19 which draws in water through the suction port 22 and air from an injector 26, 27 to balance the axial thrust the upper impeller carries a cylindrical projection above which is a space 17. The pressure in the space lies between that of the discharge 29 and the suction 22 with which the space is connected by passages 14, 11, 15. The bearings 16, 23 are cooled by water passing through the passages which are such that the water does not rise above the level of the footstep bearing 12. The casing 10 is built within or at the side of the reservoir. To prevent an air lock in the pump, the discharge leaves from the top of the pump. In a variation a division wall is built in the casing between the motor and the switch, the latter only being immersed in oil. A stuffing gland is interposed between the pump and its motor.
