Title: Improvements relating to the preparation of catalysts
IPC: B01J23/882
Filed: 1948-01-30
Abstract: <PICT:0640965/III/1> A supported cobalt molybdate catalyst for use in the hydrogenation of unsaturated hydrocarbons and the desulphurization of petroleum hydrocarbons is prepared by reacting a cobalt salt and a salt of molybdic acid in aqueous ammoniacal solution so as to form a solution of a cobalt molybdate-ammonia complex, applying the solution to a support of anhydrous porous gamma alumina or a mixture of boehmite and gamma alumina prepared by partially dehydrating boehmite and drying and finally heating the impregnated support.  Preferred reactants are cobalt nitrate and ammonium molybdate.  In an example the cobalt molybdate-ammonia complex solution prepared in steam heated vessel 14 is at 60 DEG  C. circulated upwardly through heated vessel 10 containing alumina. Circulation is stopped and the impregnated alumina dried by passing air at 120-150 DEG  C. through vessel 10 after which the dried product is heated to 550 DEG  C.

Title: Improvements in or relating to electrical switching apparatus especially adapted foruse with pneumatic tube conveying systems
IPC: H01H47/04
Filed: 1947-01-30
Abstract: 633,636. Switching systems. LAMSON ENGINEERING CO., Ltd., STEPNEY, W. J., and HALL, W. E. Jan. 30, 1947, No. 2902. [Class 38 (iv)] [Also in Group XXX] Electrical switching apparatus comprises normally-open switch contacts A which can be momentarily closed by a fast-moving carrier such as a pneumatic tube -carrier so as to discharge an electrical energy storage means, e.g. a condenser C1; wherein the operating winding of a relay RW which may operate routing mechanism of the carrier is connected in series in a low inductance circuit which connects the storage means with a source T1 of unidirectional current, and is shunted by an electrical path which has a low impedance compared with the impedance of the winding so that the electrical impulses produced when the storage means is initially charged from the source of unidirectional current do not operate the relay. As shown, contacts A in the pneumatic tube are connected to opposite sides of condenser C1 which is charged by unidirectional current from the secondary coil T1 of the transformer T which is rectified by rectifier E. Passage of the carrier in the pneumatic tube discharges condenser Cl which is then recharged from T1 and the recharging. current passes through coil RW and operates relay R. This is in two parts, Ra and Rb. The recharging current closes contacts Ra; and limit switch LS being normally closed, the current passing around circuit T1-ERW-Ra-LS continues to operate the relay until LS opens, which it is timed to do after the carrier has passed the switching points. Contacts Rb are also operated and closed. This closes the circuit Rb-D(rectifier)-T2 (transformer coil), in which circuit is placed a solenoid (not shown) which actuates the switching points. To avoid the relay being operated when the current through T is started or stopped, coil RW is shunted by capacity C3 which allows initial electric impulses to byepass the coil. The limit switch may be opened and closed respectively by the carrier pushing open a door which is restored by a counterweight or by operating a cam which is restored by a spring.

Patent GB-1087433-A (GB)
Title: Improvements in fuel elements
IPC: G21C7/04
Filed: 1965-01-22
Abstract: 1,087,433. Fuel elements. REACTOR CENTRUM NEDERLAND (STICHTING). Jan. 22, 1965 [Feb. 21, 1964], No. 2990/65. Heading G6C. A fuel element for a nuclear reactor includes at least one poison plate comprising discrete particles of a burnable poison embedded in a non-fissile carrier material. The particles which may, for instance, be composed of dysprosium, europium or a compound of one of these metals, should preferably have a particle size of 150 to 200 microns. The carrier material may, for example, be iron, an iron alloy such as stainless steel, zirconium, a zirconium compound, graphite, alumina or silica. The fuel element may comprise a plurality of fuel plates and poison plates stacked face to face, each poison plate being spaced apart from the next by one or more fuel pellets. Apertures may be provided in the plates and by varying the number or size of these it is possible to alter the amount of poison and hence the flux distribution locally in the reactor core. It is also possible by positioning the apertures eccentrically with respect to the central axes of the plates and by a suitable directioning of these apertures to exert an influence on the flux distribution locally in the core. Furthermore, the poison particles may be unequally distributed across the carrier plates, the concentration being for example greater at the outer periphery than at the inner periphery of each plate. The carrier plates may be partially or completely covered with a magnetic material, e.g. iron, or cores of magnetic material may be inserted in the apertures, this being of advantage in the removal of the plates during the processing of a spent fuel element, an electromagnet being used to extract the plates when the fuel element has been opened. In a particular fuel element, poison plates and fuel pellets are stacked alternately within jackets to form fuel elements which are supported within sheaths 13 to form clustertype fuel element assemblies. A reactor comprising such fuel element assemblies 16 is shown in cross-section in Fig. 14, control rods, e.g. 17, 22, being located in spaces between the fuel element assemblies. Referring to the control rod 22, the fuel elements 23 of the surrounding fuel element assemblies 16 which are located close to the control rod incorporate poison plates, the other fuel elements (not shown) not being provided with [poison plates. The effect of this arrangement, which counteracts " fluxpeaking " may be further intensified by making use of poison plates having eccentrically positioned apertures and mounting these plates in the reactor in such a way that the apertures are disposed towards the edges of the plates remote from the adjacent control rod surface.

Abstract: Paper for surfacing a gypsum board (see Division E1) has at least the surface to contact the gypsum board provided with a coating of cross-linked polysiloxane to prevent delamination of the paper sheet from the core.  It may be made by forming a wet paper sheet, treating one side of the sheet with a cross-linkable polysiloxane, drying the sheet and curing the polysiloxane to cross-link it.  The paper may be made on a cylinder machine having a wet calender stack and a dry calender stack, and treated with the polysiloxane at one stack and with a catalyst for its cross-linking at the other stack. Alternatively the polysiloxane and catalyst can be applied together by spray, flooding or roller in the dryer section or to the web as it is formed at the cylinders or on a Fourdrinier wire or one of them can be added to the stock before it is formed into sheets and the other applied before or after sheet formation.  The polysiloxane may be used as a solution or aqueous emulsion, and may have a structural nucleus (HSiRO)n, where R is methyl, ethyl, amyl or phenyl, and may have terminal Si(CH3)3 groups.  The cross-linking catalyst may be dibutyltin dilaurate or a lead, iron, zinc, copper, aluminium, magnesium, cadmium, cobalt, nickel, tin or sodium salt of acetic, octoic, oleic, stearic, naphthenic, lauric or resin acids or mixtures thereof.  The paper may have several plies, and may be made in a multi-cylinder machine, one surface ply being treated with the polysiloxane and the other plies sized with rosin and alum, or both surface plies can be treated with polysiloxane.

Abstract: 622,313. Braking jet-propelled aircraft. SOC. RATEAU, and ANXIONNAZ, R. Feb. 5, 1947, No. 3451. Convention date, Feb. 7, 1946. [Class 4] [Also in Group XXVI] In a jet-propulsion plant for aircraft, the propulsive effort is reduced for landing by extracting air from the augmenter stream before it mixes with the turbine exhaust and discharging it through forwardly - directed orifices. The extraction of the air into the nacelle is governed by valves m and the openings for forward-discharge from the nacelle are always open. These openings may be anywhere in the nacelle shell and may be in the lip o of the main air intake. The augmenter valve n is closed when the extraction valve m is open. In the Specification as open to inspection under Sect. 91, other arrangements are described. In the plant shown in Fig. 3 (Cancelled), air is bled from the delivery of a compressor a into a cavity in the nacelle from which it is discharged into the air-stream going to the compressor intake. The discharge is regulated by a sleeve valve p. The valves may be operated by servomotors including a limit temperature control. This subject-matter does not appear in the Specification as accepted.
