Abstract: 620,996. Two-part couplings. STANDARD TELEPHONES & CABLES, Ltd. Feb. 7, 1947, No. 3702. Convention date, March 12, 1946. [Class 38 (i)] [Also in Group XXXVII] An electromagnetic relay (see Group XXXVII) has its contact springs extended to form plug-in terminals which engage in socket terminals mounted in a socket base. The relay has four rows of three contact springs 35 ... 37 at the left, and four rows of two contact springs 48 ... 51 at the right, Fig. 1, which are held in position in co-operating grooves 68 and projections 72 formed in the relay base 23. This base consists of an insulating member 22 and insulating bars 61 ... 65, Figs. 1 and 9, which are held together by spring clips 66. The extended ends of the contact springs engage in spring clips 96 in the socket base 88, Figs. 1 and 10; these spring clips, Fig. 14, have barbs 101 which hold them in position after their insertion into suitable apertures 95 in the socket base 88 which is constructed to take two relays. The relay base has a dowel pin 91 which engages in an aperture 90 in the socket base 88 to give accurate positioning. The socket bases are fixed by screws 108 to the cross-members 106 of a ladder-like supporting bracket 105.

Abstract: 806,967. Electric incandescent lamps with cut-outs. SYLVANIA ELECTRIC PRODUCTS Inc. Feb. 4, 1957 [March 20, 1956], No. 3816/57. Class 39(2) An electric incandescent lamp is provided with a fuse 38 located within the envelope 14 in series with a filament 12 carried between two support wires 16 and 20, the support 16 being extended outwardly through one end of the envelope to a terminal pin 28 whilst the fuse 38 is supported between an intermediate part of the wire 20 and the inner end of a terminal pin 30 extending within the bulb, the fuse being disposed much closer to the said end of the envelope than to the filament. As shown the fuse 38 is supported between rigid extensions 40 welded or otherwise secured at each end and providing the parts which are fixed to the support wire 20 and the inner end of the terminal  pin 30. The support wire 20 may be extended outwardly of the envelope and, in the example, this extension and the terminal pin 28 are located on a diameter of the cap 34, with the second terminal pin 30 at the apex of a triangle having the diameter as base. The fuse element 38 is disposed at a distance from the interior wall of the bulb to reduce the possibility of damage to the glass when an overload occurs. The gap between the extensions 40 bridged by the fuse 38 is of greater length than the maximum arcing distance of the voltage normally applied to the lamp. A centralizing projection 36 on the cap is provided with an orienting key (not shown), which enters a keyway provided in a socket adapted for use with the lamp.

Title: Improvements in or relating to catalysts
IPC: B01J23/42
Filed: 1958-02-07
Abstract: Hydrous alumina is calcined to convert at least 70% to gamma-alumina, which is then contacted with water to rehydrate 10-75% of the gamma-alumina to yield a mixture which contains, preferably, 25-90% of gamma-alumina.  The resulting alumina base may be impregnated with platinum to give a catalyst.  In a preferred embodiment, hydrous alumina consisting essentially of boehmite and trihydrate is calcined, e.g. at 400-1500 DEG F., to convert 90-100% to gamma alumina, the calcined alumina is then contacted with water to rehydrate 10-75% of the gamma alumina to hydrous alumina consisting essentially of boehmite and trihydrate, and the rehydrated product is wet ground and impregnated with an aqueous solution of a platinum compound, e.g. H2PtCl6, by mixing said solution with an aqueous slurry of the wet ground rehydrated product, the impregnated alumina being thereafter preferably dried and calcined.  Instead of platinum, other platinum group noble metals or, e.g., chromium or cobalt-molybdenum may be used to impregnate the rehydrated material. U.S.A. Specification 2,479,109 is referred to.

A stator vane assembly, for example the nozzle guide vane assembly of an axial-flow turbine of a gas turbine engine, comprises a fully annular (i.e. an unsplit) casing and a plurality of stator vanes each having a vane platform at its outer end, each of a number of the platforms having its circumferentiallyspaced end surfaces parallel and projecting into a corresponding one of an equal number of circumferentially-spaced parallel-sided notches in the casing, and each of the remaining platforms having plane end surfaces inclined to each other at such angles that when the vanes are assembled in the casing, the platforms form a complete annulus with the end surfaces of the platforms in contact. The fully annular casing 10 is formed with internal circumferential ribs 17 each of which is formed with peripheral grooves 16 open at the down-stream end, and with parallel-sided notches 23 equal in number to half the number of nozzle guide vanes 11. The platform 13 of each alternate guide vane 11 has its circumferentially-spaced end surfaces 13a formed as planes parallel to one another and to the radius 13b from the axis of the turbine through the centre of the platform 13, the platforms 13 being engaged in the notches 23. The circumferentially-spaced end surfaces 33a of each of the remaining platforms 33 are formed as plane surfaces which are inclined to one another, these surfaces in the assembly engaging the surfaces 13a of the adjacent platforms 13. The vanes are all located in the circumferential direction by engagement of the platforms 13 in the notches 23. All the platforms 13 and 33 are formed with axial flanges 15 which upon assembly engage the peripheral grooves 16 to locate the vanes radially, and with radial flange portions 19 which in the assembly are located between a pair of rings 20, 21 so as to locate the vanes axially. The platforms 33 are cut away so as to clear the portion of the circumferential rib 17 between the notches 23. The circumferentially-spaced end surfaces of the inner platforms 12 are formed parallel to corresponding surfaces of the outer platforms 13, 33. The end surfaces of the vane platforms may.lie in axial planes or they may lie in planes helically disposed.

Filed: 1939-02-13
Abstract: 525,060. Coating paper. DYKES, W. U. (Warren Co., S. D.). Feb. 13, 1939, No. 4696. [Classes 96 and 140] In apparatus for coating fibrous sheet material such as paper of the kind in which a layer of fluid 'coating composition is deposited on an impervious transfer surface, smoothed by a doctor and transferred to the fibrous sheet, an air doctor disposed transversely of and parallel to the plane of the transfer surface is used. The transfer surface may be a roll or endless belt of metal or rubber. The air doctor may be provided with means for varying the distance between it and the transfer surface, the thickness of the sheet of air, and the angle at which it is projec'ted. Suitable air doctors are those described in Specification 483,998 or U.S.A. Specification 1,980,923. Duplicate equipment may be used to coat both sides of the web simultaneously. As shown in Fig. 1, a web of paper 1 from a Fourdrinier wire 2 is pressed between rolls 3, 4 and passed between rolls 5, 6. Roll 5 dips into a tank 9 supplied with fluid coating composition from a storage tank 8 by a pump 13. The coating picked up by roll 5 is smoothed by an air doctor 12 and transferred to and squeezed into the web as it passes between rolls 5, 6. Roll 5 may rotate in the same or opposite direction to that of the web, and its peripheral speed may be the same, or greater or less than the speed of travel of the web. In the modification shown in Fig. 3, the coating material may be delivered from tank 9 to an applying roll 18 by a roll 22 and the web may be held against roll 18 by its own tension between rolls 23, 24. The roll 18 may be replaced by an endless belt, whereby, if desired, the coating composition may be thickened by evaporation during its travel on the belt.
