Title: Vacuum tube with magnetic or electric, or both magnetic and electric, control of the charged electric particles, as well as amplifiers and the like in which such tubes are used
IPC: H01J21/14
Filed: 1934-04-12
Abstract: 436,533. Discharge apparatus. JENSEN, C. A. S., 56, Hyldegaardsvej, Charlottenlund, Copenhagen. April 12, 1934, No. 11075. Convention date, April 12, 1933. [Classes 39 (i) and 40 (v)] In a discharge device in which electrons or positive ions pass from an emitting electrode through one or more apertures in an anode and are deflected by controlling means, the electrons &c. are concentrated by plates or other means so as to follow definite paths through the apertures, and means called a " renode " which may produce an electrostatic or electromagnetic field or consist of a mechanical obstruction, is arranged outside the anode and serves to deflect the electrons passing through the anode. The "renode" may consist of a metal envelope, a coating on the inside of a glass envelope, charged particles on a glass envelope, an electrode inside or outside the envelope, or a winding producing an electromagnetic field; the "renode" may act as the controlling electrode. As shown in Fig. 10, two concentrating plate electrodes s are mounted parallel with a cathode k so as to direct electrons through apertures c in a cylindrical anode a. The " renode " b reflects electrons so that they are collected by the outside of the anode. The electrons may be controlled by an electromagnetic field, or by the electrostatic field of the " renode " or by both. The apertures may be arranged obliquely in the anode, and the plates s may be replaced by a perforated electrode parallel with the anode. A perforated electrode may be arranged outside the anode to serve as a screen intercepting some of the electrons reflected by the "renode." A control grid may be arranged parallel with the anode. The "renode," should be of small dimension in a plane at right angles to the direction of the lines of force of the electric controlling field. In the device shown in Fig. 6, the anode consists of four angular parts a<1> .. a<4>, and the concentrating electrode s is similarly constructed. The electrons passing through the aperture c' in the anode are deflected by an electromagnet field produced by a winding C so as to pass along the path 3, the electrons being successively repelled by the cathode k and deflected by the field until they meet the anode part a<4>; a " renode " producing an electrostatic field may also be provided. In the arrangement shown in Fig. 5a, the input circuit is connected with a winding C producing a magnetic controlling field; the winding is maintained at a negative potential by means of a battery B and acts as an electrostatic "renode." Electrons from the cathode k pass through apertures in the anode a, and some are intercepted by a screen r after reflection. In the arrangement shown in Fig. 13, four "renodes" b are provided, and perforated screens r are arranged at the edges of the anode to intercept reflected electrons. Specification 424,035 is referred to.

Abstract: 995,243. Injection moulding machines. C.I.C. ENGINEERING Ltd. March 30, 1962 [March 30, 1961; Sept. 11, 1961], Nos. 11686/61 and 10996/62. Divided out of 32485/61. Heading B5A. An injection nozzle assembly comprises a nozzle 5 which is longitudinally displaceable by to a charging position in direct contact with a mould, without relative movement between the injection cylinder and the mould. In one embodiment (Fig. 2) the nozzle 5 is slidably mounted in a sleeve 6 which is slidable within a nozzle body 8. Passages 13, 18, 12 in the parts 8, 6, 5 respectively are made to co-operate by forcing the parts 6, 5 downwardly by a ram 17. When the nozzle 5 is in contact with a mould orifice 11 (Fig. 1, not shown) channels 12, 13 coincide and the sleeve 6 must then be depressed further to bring the three channels into alignment so that the plastic may be injected. After injection the ram 17 is retracted and the sleeve 6 is pushed up by a spring 19 to cut off the flow of plastic before the nozzle 5 breaks contact with the mould orifice 11. In another embodiment (Fig. 5) the nozzle 5 is displaced by pivoted levers 38 which are actuated by a fluid cylinder unit 44. In the injection position the material flows through a bore 29, a passage 50 in a slidable valve rod 49, a connecting port 31, and delivery passage 12 in nozzle 5. The rod 49 is operated by a fluid cylinder unit 52 so that, during injection, the passage 50 coincides with bore 29, and during non-injection an inclined passage 54 coincides with bore 29 so that the material is returned through a by-pass tube 47 to the base of the feed hopper. Moulds 10 for moulding footwear may be mounted on a rotary table 9.
Patent GB-710339-A (GB)
Title: Improvements in or relating to the synthesis of hydrocarbons and catalysts therefor
IPC: C07C1/04
Filed: 1950-05-10
Abstract: Olefinic hydrocarbons are produced from a synthesis gas containing CO and H2 and substantial amounts of N2 by contacting at 450-650 DEG , preferably 550-650 DEG  F., and 50-100, preferably 55-75 p.s.i.g., with a dense turbulent fluidized catalyst comprising iron on active carbon and promoted with an alkali metal compound.  Such catalysts give H2/CO consumption ratios greater than the ratio in the feed whereby a once-through operation can be used with synthesis gas obtained by partial oxidation of natural gas and having a H2/CO ratio of 2 : 1.  In view of the low pressure required, the synthesis gas may be produced by oxidation of coal or natural gas with air at similar low pressures.  The synthesis may be effected with a gas throughput of 2-20 c.ft./lb. of catalyst/hr. at a linear velocity of 0.1-3 ft./sec.  The preferred catalysts comprise 10-20 per cent reduced iron and 0.4-1 per cent promoter, e.g. potassium carbonate. The iron is distributed over the active carbon as by impregnation or by thermal decomposition of iron carbonyl. Natural gas is oxidized with air at 2000-2500 DEG  F., the lower part of the reactor containing a reforming catalyst such as nickel or copper on alumina to convert any CO2 and H2O formed back to methane.  The synthesis gas passes to a reactor containing powdered catalyst which is fluidized by the upward flow of gas. Liquid products are separated while the gaseous hydrocarbons may be recovered by adsorption in active carbon also in fluidized form.  Where synthesis gas is obtained from coal, a further conversion to increase the H2/CO ratio from 1/1 to 2/1 may be effected.  Examples illustrate the effect of varying the promoter (K2CO3) content.  Other promoters may be used, e.g. potassium hydroxide, acetate or fluoride. Specification 649,464, [Group III], is referred to.ALSO:A catalyst for the synthesis of hydrocarbons from CO and H2 comprises iron or active carbon promoted with an alkaline metal compound, and in finely divided form, for example 100-400, preferably 150-200 mesh, suitable for fluidization.  The preferred catalyst contains 10-20, especially 15 per cent. reduced iron, and 0.4-1, especially 0.4-0.6 per cent. potassium carbonate, the iron being distributed over the carbon carrier as by impregnation or decomposition of the carbonyl.  Other promoters include potassium hydroxide, acetate, and fluoride.  The promoter content depends upon the iron surface area and examples illustrate the variation in product quality with contents below and above an optimum 0.5 per cent.
