Title: Improvements in or relating to pulverising or disintegrating apparatus
IPC: B02C13/12
Filed: 1947-06-24
Abstract: 644,387. Grinding and crushing. AMANCIC, F. K. June 24, 1947, Nos. 16627 and 16628. Convention dates, July 12, 1946 and May 14, 1947. [Class 59] Apparatus for the disintegration of materials comprises a rotor disc revolving within a peripheral ring of chambers or cells inclined forwardly in the direction of rotation of the rotor, the rotor disc being provided at or near its periphery with grinding or eddying members, which, at least at their edges remote from the rotor disc, are similarly inclined with respect to the inner periphery of the ring of chambers or cells at an angle substantially equal to the angle of inclination of the admission surfaces of said chambers to said periphery, said eddying members extending in the direction of the rotor axis at least along the whole length of said chambers. In one construction a disc 6, Figs. 1, 2, provided on its front face with beaters 7, arranged near the centre, and with guides 8 at the periphery and on its rear face with guides 9, revolves within a cylindrical casing 1 to the inside of which are fixed two rings of chambers or cells 10, 11, the cells being inclined forwardly in the direction of rotation of the disc and open at one end, the length of the chambers in the direction of the rotor axis being less than the length of the surrounding casing. The admission or forward faces of the cells are inclined at the same angle #, Fig. 7, to the radii of the rotor as are the guides 8, 9. The ring of chambers 10, surrounding the members 8, extends all round the periphery of the casing 1, while the ring of chambers 11, surrounding the members 9, extends only around the upper part of the casing, the lower part being formed with a discharge grating 12. This grating may be in the form of pivoted slots 24, Fig. 21, given a variable inclination by the operation of a lever 27 and rods 26. An axial discharge outlet may be provided in place of the grating 12. Material is fed through an inlet 14 and air through an inlet 15. The chambers may be of various shapes and, in the axial direction, may be inclined relative to the axis of rotation of the rotor. A fan may be used in conjunction with the mill, the inlet 14 may be axial, and the rotor may be adjustable axially to vary the width of the annular passage between one ring of cells 10 and the succeeding ring 11, the rotor disc then having a coned periphery. A rotor disc 19, Fig. 15, rotating in the opposite direction to the disc 6 may carry the ring of chambers 10 at its periphery and the guides 9 on its rear face. A number of rotors may be mounted on the same shaft, and the chambers of succeeding rings may be given successively increasing inclinations to the rotor radii. The blades 8, 9, may be given a stepped form, Fig. 31, and co-operate with two pairs of rings. As a result of alternate high and low pressure eddies propagated in the chamber by the grinding members an internal bursting of the particles of material is said to take place.

Title: Supervision of the control of telecommunications switching networks
Inventor: GRUNDY BRIAN
IPC: H04Q3/54
Filed: 1970-04-08
Abstract: 1293441 Automatic exchange systems PLESSEY CO Ltd 19 April 1971 [8 April 1970] 16629/70 Heading H4K In a switching network of the type employing reed relays each with a make contact in series with its operate coil and a marking diode connected to the junction of the contact and coil, all the input marking leads pertaining to a stage of the network are connected to a detector device which must respond to the appearance of marking potential advanced from a succeeding stage of the network via the diode associated with the relay it is required to operate before the co-ordinate marking potential is applied to the relevant input marking lead. If the succeeding marking potential does not appear, further setting up of the chosen path is inhibited and details of the fault are forwarded to a stored programme processor for further action. Although this fault detection system is useful throughout exchange life, it has particular relevance during the initial cut-over period, The central processor (not shown) determines a path between a calling inlet and a suitable outlet with the aid of a memory map and supplies network control SMC with the path details. The latter, by appropriate operation of relays HM and contacts PZ, completes a high resistance marking tree to the chosen outlet. Provided that this outlet is not seized, i.e. is not at - 38v., that the relay coil is intact and that marking diode DD is not forward biased, the high resistance - 100v. marking is noted by detector D which has decoupled inlets to all the input marking leads extending towards the last stage matrices (corresponding marking inlets of each switch are multipled and of course each inlet serves a column, or row, of crosspoints-hence the double multipling symbols). The detector informs SMC of the successful conclusion of the test whereby SMC substitutes low resistance negative battery by operating a contact Z and also connects - 70 volt battery to that input marking lead pertaining to the required crosspoint by operating contact 1M. Consequently the relevant D relay should come up and forward the - 70 volt marking via its closed contact D1 to the next preceding stage. If this potential is detected by device DETC, SMC is allowed to proceed with the operation of the relevant C relay. The process repeats up to the A relay. If all goes well, gate GSC is opened to inform the control SMC, which thereupon conveys the information to the processor so that the network map may be updated and also clears the marking circuitry. In the event of a detector not responding, the control SMC is informed via gates GA-GD of the location of the fault so that the processor may take action, a timer T enabling these gates if the connection is not completed within say 25 m/secs.

Title: Dielectric walls for transmission of centimetric radiation
IPC: H01Q1/42
Filed: 1956-06-01
Abstract: 821,250. Laminates. McMILLAN, E. B., and REDHEFFER, R. M. June 1, 1956, No. 17069/56. Drawings to Specification. Class 140. [Also in Group XL (c)] The Specification gives a number of examples of laminated dielectric material, the various layers in laminate having differing dielectric constants and controlled thicknesses so that the material is suitable for the construction of a radiation-transmissive housing for a radio aerial. The material has a core of relatively high dielectric constant and an outer layer or layers on each side of the core of lower dielectric constant. In one example the core layer is a polyester resin, fibre glass cloth laminate loaded with rutile titanium dioxide and to each side of this is attached a sheet of butyl rubber composition. In a modification of this the same core layer is used but on one side of it a layer of rigid polymethyl methacrylate is attached and, on the other, a layer of plasticized polyvinyl formal. In another example the core layer comprises plasticized polyvinyl formal loaded with rutile titanium dioxide and both outer lamina of rigid polymethyl methacrylate. In a further example the core layer consists of fibreglass cloth impregnated with polyester-styrene resin and loaded with fine aluminium powder and both outer layers of nylon. A similar core layer to that last described is used in another example and is laminated with a resin-impregnated fibre-glass mat on each side. An extra erosionresistant layer is added on the side intended to be outermost and consists of a vulcanized rubber loaded with zinc and magnesium oxides. In an example having a high strength to weight ratio the core layer is of fibreglass impregnated with polyester-styrene resin and loaded with aluminium powder. On either side of this is a cellular resin foam layer loaded with a small amount of aluminium powder. On the outer sides of these layers are layers consisting of parallel warps of glass fibres bonded with polyester styrene resin. Finally there is an erosionresistant layer of vulcanized synthetic rubber compound on one side only of the material. An example of a heat-resistant laminate comprises a porcelain core with outer layers of polytetrafluoroethylene. In another construction described the core layer is of a glass containing 96% silica and the outer layers of mahogany wood veneer. In a final example the core is made of a ceramic of mica, glass, and titanium dioxide, the outer layer intended to be on the outside of the housing is a solid dispersion of polyvinyl chloride-acetate resin in alkyd resin and the other outer layer of poly-N-vinyl carbazole.
