Inventor: SCOTT WILLIAM JOSEPH
IPC: C04B37/02
Filed: 1959-11-12
Abstract: 903,824. Ceramic-metal seals. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Dot. 19, 1960 [Nov. 12, 1959], No. 38440/59. Class 36. In an annular ceramic-metal seal, in which one part surrounds the other, thermal stresses are avoided by using an intermediate metal joined to both parts such that one of the metals has a thermal expansion greater, and the other less, than that of the ceramic so that their combined rate of contraction on cooling equals that of the ceramic. The ceramic may be the inner or outer member, and the cross-sectional areas of the two metals must be chosen such that their combined contraction after sealing equals the contraction of the ceramic. The intermediate metal body may be an annulus of malleable metal and the ceramic surface may be metallized in the region of the seal. This method of forming a seal is especially suitable for sealing a molybdenum rod into an aperture in a high-alumina ceramic body when the intermediate body is a copper sleeve and the brazing metal is a copper-silver eutectic-alloy.

Title: Method of Mulling and Heat-Setting in Shoe Manufacture
IPC: A43D11/14
Filed: 1966-08-30
Abstract: 1,160,691. Boots &c. COMPO SHOE MACHINERY CORP. 30 Aug., 1966 [27 Aug., 1965], No. 38682/66. Heading A3B. A method of mulling and heat setting a shoe upper includes the steps of penetrating at least a portion of the upper with a solution of a wetting agent, and thereafter subjecting the wetted upper, whilst on a last, to force draught drying. The solution of the wetting agent, e.g. a detergent, may be sprayed on to the shoe upper before or after lasting. The forced draught drying takes place in a stream of heated air moving at a velocity of 4,000 feet per minute at a temperature between 175‹F. and 300‹F., and may be followed by forced draught cooling in which air at ambient temperature is blown over the upper. Apparatus for performing the method consists of a rotor 18 (Fig. 3) which is divided into compartments by vanes 20 and which rotates in a housing 22 having an opening 24 for loading and unloading. After loading the uppers pass by sprays (not shown) which wet the upper and then into the housing 22. Region W is an air lock and in region X the uppers are subjected to forced draft drying. Region Y is a further airlock and in region Z the upper is subjected to forced draft cooling. If the upper is to be wetted before lasting the upper 10a is hung on a hook 38 (Fig. 6) in a housing 34 which is then moved past sprays 32. The upper may be subjected to additional moisturizing with water vapour following the spraying operation.

Abstract: 1,146,725. Preparing dialkyl phosphites. STAUFFER CHEMICAL CO. 31 Aug., 1966 [14 Sept., 1965], No. 38889/66. Heading C2C. A dialkyl phosphite is obtained by reacting PCl 3  with a C 1 -C 4  alkanol, the alkanol being saturated with hydrogen chloride prior to the initiation of the reaction. Specified alkanols are methanol, ethanol, n- and iso-propanol, and n- and iso-butanol and they should be substantially anhydrous to achieve a high yield of product. A suitable working temperature range is between - 20‹ and 80‹ C., preferably 0‹ to 45‹ C. In a preferred form of operation a continuous process is used in which a thermosiphon reactor is employed to force the reaction products to overflow into a stripping column in which an inert solvent, e.g. toluene, hexane, xylene, benzene or chlorobenzene, is constantly refluxing under conditions which cause the separation of the desired phosphite product from the by-product and excess reactants. The thermosiphon reactor consists of a closed loop with a disengaging chamber at the top for the escape of HCl gas bubbles, an overflow leg for passing the reaction product to the stripping column and a heat exchanger in one of the main legs to provide a small amount of cooling. It is also desirable to introduce an inert gas, e.g. nitrogen, into the reactor to ensure a steady flow in the latter. Detailed examples are given for the preparation of dimethyl- and diethylphosphites.

Abstract: 373,996. Railmay signalling interlocking frames. VEREINIGTE EISENBAHN-SIGNALWERKE GES., Siemensstadt, Berlin. Dec. 30, 1930, No. 39220. Convention date, Dec. 31, 1929. [Class 105.] In an interlocking frame in which handlevers actuate switch drums for the electrical operation of the points and signals, the switch drums are arranged in a plurality of columns either directly above each other, or staggered, or behind each other, to permit their tappet bars to be arranged at the minimum distance apart determined by the construction of the locking elements and thereby to give a compact arrangement. In the diagrammatic plan, Fig. 4, the points lever switch drums 53 .. 58 actuate tappet bars 63 .. 68 which are engaged by locking pieces on rods 60, 61, 62 actuated through bell cranks by rods 80, 81, 82 connected to track lever switch drums 50, 51, 52. A track lever when operated locks the points set and the conflicting points and clears the signals. If the size of the locking pieces 72 is such that the tappet bars 63 .. must be spaced a distance t and if the length B of the switch drums is three times such distance t then three drums are included in the column or file. The bell cranks are such that the rods 80, 81, 82 have a greater movement than their tappet bars 60, 61, 62 so that the track lever switch drums 50, 51, 52 have a large movement. The rods 80, 81, 82, and their tappet rods 60, 61, 62 each carry locking-pieces for interlocking with each other. As shown in Fig. 5, the small movement of the tappet bar 61 moves its locking piece 97 to prevent movement of the rod 80 actuated by a conflicting track lever switch drum. The track levers in addition may actuate contacts for current of a different voltage, and in Fig. 6 such contacts comprise discs 100 .. 105 separate from the switch drums and actuated by the rods 80 .. 85. The rods 80 .. 85 also actuate tappet bars 60 .. 65 and the arrangement is such a - adjacent rods such as 80, 81 actuate alternately situated tappet bars 60, 61. The springs 95 of the contact discs are protected by the extension lugs 91 to which the electrical connections are made. The contact discs 1.00 .. 105 may be enlarged if they are arranged at different levels.

Abstract: 1315505 Radar LICENTIA PATENTVERWALTUNGS-GmbH 14 Aug 1970 [29 Nov 1969] 39228/70 Heading H4D A radar installation has at least two independently operated overlapping primary radars each combined with a secondary radar arranged to provide a mosaic display on a common display screen, means for selecting desired targets, and switching means actuated by whichever display zone contains a selected target, for selecting information from that secondary radar which is combined with the primary radar whose information is displayed in the said zone. Two primary radars produce polar co-ordinate PPI displays on storage tubes in units 11, 12. These displays are synchronously scanned by a TV raster produced by generator 4. The two readout video signals are passed to a switch in unit 24 which is controlled to select signals from the radar chosen to provide the display for that zone of the mosaic display which is being scanned at that instant. The switch is controlled by a comparator which is fed with the line and field deflection voltages and information from a data store which defines the boundary between the two zones of the mosaic display. A joy-stick or light pistol control 3J positions a target selection marker on the TV display (3). The bright-up pulse U sym b for the marker passes to two AND gates 38, 39 which are also supplied with complementary signals U s1  and U s1 inv which indicate the position of the video selection switch of unit 24. The gate outputs define the bi-stable 37 output to close either switch 35 or 36, the closed switch being associated with the primary radar being utilized when U sym b is produced. Voltages X roll  and Y roll  defining the marker position are corrected in units 25, 26 for offset of the primary radar sites and compared with the polar PPI deflection voltages (Fig. 4, not shown). When these are equal the secondary radar information from the selected target is passed through the closed switch 35 or 36 to the appropriate decoder which provides a read out of target interrogation, height, target codes &c.

Abstract: 345,991. Friction materials for brakes. WHITE, A. E., 5, Quality Court, Chancery Lane, London.-(Union Asbestos & Rubber Co. ; 310, South Michigan Avenue, Chicago, U.S.A.) Dec. 24, 1929, No. 39447. [Class 103 (i).] In order to prevent the heat due to friction from producing silica, carbides, slags or other hard substances in felted or woven asbestos material consolidated by a resinous binder and used in clutches, brakes, and the like, metallic lead or a lead alloy, such as antimony lead, is incorporated with the asbestos so as to be exposed upon the surface. Scratching of pressed steel drums or other parts, squealing, and vibration are thus prevented. The hard substances are produced by chemical reactions between the constituents of the asbestos or between the asbestos and particles of steel, carbon, &c. removed from the drums. The lead &c. may be woven into the fabric or may be in the form of small strips or wires. Felted bands are made by passing an endless carrier through a vat containing a pulp or cream of asbestos fibres and water. Cellulose fibres and chemicals to act as a filler may be present. The band is built up of plies of fibres deposited on the carrier by sucking water therethrough. Lead strips or wires may be mixed with the pulp, but are preferably sprinkled between the plies. The band is dried and impregnated with resinous binder. In the woven band shown in Fig. 2, lead or lead alloy wires 12 may be woven with the strands, or lead wires &c. may coat or may be spread between the strands. Brass reinforcing wires 14 may be woven into the material. Cotton may be twisted with the asbestos fibres to strengthen the material.

Abstract: 1314108 Deflecting propulsion jets GENERAL ELECTRIC CO 18 Aug 1970 [3 Nov 1969] 39720/70 Heading B7G [Also in Division Fl] The invention relates to a propulsion nozzle in which noise suppression means are provided, see Division Fl. One embodiment is shown in Fig. 11 in which sector members 82 are moved to a noise suppression position in which the hot gases pass through tubular members 86 mounted on the sector members, also through tubes 84 in a ring member 80 on which the sector members are pivotally mounted. For thrust reversal, the ring member 80 together with the sectors 82 is moved axially downstream of the blow-in air passages, see Fig. 12, the sectors being in their inward, noise suppression position. The ring member 80 engages against the fixed ramp 92. Butterfly valves 94, 96 in the tubes 84, 86 are closed so as to block downstream flow of the hot gases which are thus deflected laterally and forwardly to provide reverse thrust. Movement of the flaps is controlled by an axially movable ring member 106 which is connected to the sectors 82 by linkage 104, 98, the link 104 having a member which engages a cam slot 110 formed in pivotally mounted bracket 100.

Abstract: 1,162,588. Clutch control. BAIA CORP. 31 Aug., 1967 [6 Sept., 1966], No. 39783/67. Heading F2L. [Also in Division G2] A cine film viewer or editing machine has an electric motor driving a spindle 40 through reduction gearing whose output gear 70 drives spindle 40 through a helical spring clutch 74. When gear 70 rotates in a film-winding direction, the coils of spring 74 contract to grip and drive spindle 40. A small biasing current is therefore applied to the motor when its spindle is not to be driven to give a reverse rotation which disengages the clutch. Each spindle has braking washer 116 providing drag to prevent over-run of the spools.
