Title: Method of making porous electrode bodies serving as carriers for the active material of alkali type storage batteries
IPC: H01M4/88
Filed: 1960-03-02
Abstract: Porous electrodes for use as carriers of active material in alkali type storage batteries are produced from a mixture of powdered or granular graphite and at least 10% of metal powder such as Co or Ni which is pressed on a supporting member and sintered at a temperature below the melting point of the metal. Fillers such as NaCl or metal oxides, e.g. NiO, may also be added to the mixture and sintering is effected under a protective atmosphere of N2, N2+H2 or an inert gas at a pressure of several atmospheres.  To prevent evaporation of the fillers during sintering an additional quantity of these fillers may be placed in the sintering furnace.  Fine metallized graphite powder the particles of which are coated with the particular metal may also be used and the strength of the electrode is increased by incorporating wires, networks or metallic sheets into the powder.ALSO:Porous electrodes for use as carriers of active material in alkali-type storage batteries are produced from a mixture of powdered or granular graphite and at least 10% of metal powder such as Co or Ni which is pressed on a supporting member and sintered at a temperature below the melting-point of the metal.

Title: Improvements relating to the catalytic treatment of alkyl aryl hydrocarbons
IPC: C10G47/08
Filed: 1962-02-26
Abstract: The isomerization of alkyl aryl hydrocarbons having 8 carbon atoms per molecule, while reducing the content of ethylbenzene, is effected at 454-510 DEG  C. and not less than 400 p.s.i.g. in the presence of hydrogen and a catalyst comprising a hydrogenating dehydrogenating component on a support consisting of alumina and 1-15 weight of fluorine which fluorine is added to the support after the hydrogenating / dehydrogenating component. The isomerization of xylenes containing ethylbenzene is effected at 400-1500 p.s.i.g. and 0.1-10 vol.vol./hr. using 100-10,000 ScF/B hydrogen.  The catalyst is preferably produced by impregnating alumina with a Group VIA and/or VIII metal or compound thereof and thereafter fluorinating with a compound of the formula XY2F2 in which X is carbon or sulphur and Y is hydrogen or fluorine.

Abstract: 1,148,646. X-ray micro-analyser. CAMBRIDGE INSTRUMENT CO. Ltd. 13 Feb., 1968 [16 Feb., 1967], No. 7462/67. Heading H5R. In a micro-analyser, a finely focused electron beam impinges on the surface of a specimen, the X-rays so produced are detected by at least 3 separate crystal or grating spectrometers, the electron beam is scanned along a datum line on the specimen, and spectrometers are arranged around the specimen such that the plane of each spectrometer, that is the plane defined by the directions of the incident and reflected X-ray beams, contains a line which is perpendicular both to the datum line and to the path of the rays incident on that spectrometer. Preferably the spectrometers are arranged symmetrically on each side of the plane containing the axis of the electron beam and the datum line. Two or more of the spectrometers may be arranged such that they have a common privileged plane, that is a plane perpendicular to the spectrometer plane and containing the direction of the incident beam. The spectrometers may have the same angle between the specimen surface and the incident ray. The spectrometers may also be arranged symmetrically about a plane that contains the mid-point of the line scanned on the surface of the specimen by the electron beam and is perpendicular to the datum line. During the analysis the specimen itself may be moved in a direction perpendicular to the datum line.

Title: Improvements in illuminating systems for optical projectors
IPC: G03B21/20
Filed: 1951-03-30
Abstract: 711,701. Optical projection systems. GRETENER, E. March 30, 1951 [March 31, 1950], No. 7476/51. Class 97 (1) [Also in Group XL(a)] A concave reflector forms an intermediate image of a high intensity blow arc and a condenser forms a further image of the intermediate image in the projection aperture, the light beam from the concave reflector being reflected by a plane mirror so that the intermediate image lies outside the said beam between the concave reflector and the plane mirror. As shown, Fig. 3, the crater on the positive arc carbon 18 is disposed at one focus of an ellipsoidal mirror 11 which, after reflection of the light beam 13 at a mirror 16, forms an enlarged image of the crater at 14 which is in turn imaged by the condenser 15 on the projection aperture. The positive carbon passes through a hole in the mirror 16. The negative carbon may be a ring encircling the mirror 16 and rotated continuously. The angle a may be 90 degrees or less. The concave mirror may be as in Specification 645,376, i.e. of the form produced by rotating an ellipse about an axis slightly inclined to its major axis. With such a mirror there is an optimum position for a diaphragrii to exclude from the light beam rays which would fall on the gate but not pass through its aperture. In Fig. 7 the plane mirror 30 transmits infra-red radiation to a fluid-cooled absorber 31. The condenser may be in two parts 33, 34 with adjacent plane surfaces at least one of which has an infra-red reflecting coating to return any such radiation returning to the mirror 30.

Abstract: 526,201. Coal-cutting machines. ANDERSON, A., and ANDERSON, BOYES & CO., Ltd. March 10, 1939, No. 7776. [Class 68 (i)] [Also in Group XXX] A coal-cutting machine is provided with a cutting-sweeping device comprising a powerdriven disc rotatable about a substantially vertical axis and having its peripheral edge adjacent the cutter-chain to receive and remove the cuttings therefrom, and at least one helical conveyer so placed as to sweep the cuttings from the disc to the desired point of delivery. The machine 1,- with cutter chain 3, has bolted &c. thereto a two-part housing 6, 7, supporting on a substantially vertical axis a shaft 8 carrying a disc 9 which may be flat or dished. The shaft 8 is driven from the machine through shaft 13, dog clutch members 14, 14b, pinions 12, 11, 10, and bevels 8a or worm gearing; when the, chain jib is swung to operate on the other side of the machine, the housing 6, 7 is adjusted to effect the drive through clutch members 14, 14a, to compensate for reversal of the machine motor. The housing includes a chute 16 which encloses a helical conveyer 15 which sweeps the cuttings from the disc 9. Barriers 18 prevent spilling from the disc, and a scraper plate 19 guides the cuttings to the conveyer 15. The arrangement may be such that reversal of the motor reverses rotation of the disc 9 without reversing rotation of the conveyer 15, and the plate 19 is then removable to the opposite side of the conveyer. The housing parts 6. 7, may be adjustably connected to allow variation of the point of delivery of the conveyer.

Each strip of which there are two 15 has an aperture 16 and each aperture is engaged by a respective lug 17 on the plate 11. Each strip either has its slots 19 arranged at right angles to the longitudinal axis and its worm mounted at an angle to the axis so that its threads can engage the slots or the slots are at an angle and the axis of the worm is parallel to the longitudinal axis of its strip. Sealing gaskets 14 of rubber or synthetic material having similar properties, are provided between the two clamping plates to engage the window pane or wall and these are attached to the plates by providing integral pips 28 located in apertures 29 in the plates. In a modification the gaskets are located by providing a turned over bead on the outer periphery of each plate. In a further modification instead of providing the strips with apertures 16 they pass through apertures in the clamping plate 11 and the end is turned over to prevent it being withdrawn from the aperture.
