Title: High pressure mercury vapour discharge lamp
IPC: H01J61/20
Filed: 1975-05-07
Abstract: 1498258 Metal vapour lamps PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 7 May 1975 [9 May 1974] 19166/75 Heading H1D In a high pressure Hg lamp, with or without electrodes, the volatility of the alkali or alkali earth metal halide (Cl, Br, I) responsible for light emision is increased by introducing volatile Al halide (Cl, Br, I) forming a gaseous compound with the first halide. In two designs of conventional double-walled envelope 400 W HP lamp running with silica arc tube wall temperature of 700-800‹ C., containing Hg and inert gas (e.g. Ar), NaI is made volatile with AlCl 3  or NaBr by AlBr 3 , combined chlorides being efficient but tending to attack W electrodes, leading to wall blackening. The molar proportions of the two halides should be near 1 :1. Octer volatile-halide-forming metals may be partially substituted for Al; in general a highly volatile halide which forms a dimer in the vapour and a poorly volatile halide which also forms a dimer in the vapour are likely to combine to form a volatile letrodimer : volatile halides of Fe<SP>+++</SP>, Tl<SP>+</SP>, In<SP>+++</SP>, Sn<SP>++</SP> are suitable. With Na halide present, the increased volatility tends to shift the colour temperature, but this may be compensated by varying the composition of the volatile halides. Other alkali metal or alkali earth metal halides together with other poorly volatile halides (other than-F) such as those of Cd, Ga, Sc, Y or rare earths may also be substituted for Na halide.

Title: Device for removal of the backbone and side bones of fish
IPC: A22C25/00
Filed: 1936-07-11
Abstract: 462,435. Dressing fish. PEDERSEN, C. H. July 11, 1936, No. 19267. [Class 28 (ii)] A device for removing backbones and sidebones from fishes, particularly herrings, after their heads and tails have been cut off, comprises a gouge or channel-shaped implement 1 having a handle 2 at one end, and, adjacent to the handle, an inclined surface 3 over which the bones are ejected from the device. In use, the device is pushed longitudinally through the fish with its bottom closely above the backbone and is then rotated about its longitudinal axis and finally withdrawn with the bones in the channel. The surface 3 may be integral with the implement, e.g. struck up therefrom, or it may be formed separately and soldered or welded in position, and may be of such length that its free end enters the handle to render it more rigid. The width of the channel may be increased adjacent to the surface 3, and the said surface may be directed towards the side of the channel. The device may be mounted to rotate in a stand, a turning-handle being provided. A spring locking-device secures the chanelled member in the correct position for insertion into the fish which may be held in a sliding trough, or, alternatively, the whole device may be slidable to be pushed towards a fish held in the hand.

Abstract: 349,811. Mechanical stokers. WESTINGHOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, U.S.A. - (Assignees of Miller, C. F.; 1319, Lincoln Avenue, Moore, Pennsylvania, U.S.A.) June 26, 1930, No. 19450. Convention date, July 26, 1929. [Class 51 (i).] In mechanical stoking apparatus, preferably of the underfeed type, in which the grate comprises a series of endto-end sections over which the fuel is fed, a sliding movement is imparted to the first section, while some or all of the others are moved angularly about axes transverse to the direction of the feed. Fuel is fed along the underfeed trough 15 by a ram, and spreads over side grates 16 formed of sections 35 .. 38 pivoted together, and slidably supported at the ends on flanges 31 on the trough, and on beams 66, and intermediately on rocking-plates 68, 69. A combined oscillating and reciprocating motion is imparted to the sections by arms 70 mounted on a shaft 76, which is rocked bv a link 82 and lever arm 81 from a rock shaft 80 geared to the stoker ram. The arrangement of the plates 68, 69 in relation to the grate sections is such that the degree of oscillatory motion decreases in the direction of the fuel feed. Each grate section comprises a rectangular frame 39, Fig. 4, with side extensions 53 adapted to embrace a tongue portion 55 on the adjacent section. The pivot pins fit tightly in the extensions 53 and loosely in the tongue portions. The grate bars 42 carried by the frames are notched at the ends to interlock with ribs 43, and these ribs are notched at 46 to allow the bars to be inserted one at a time into the frame and then slid into position. The last bar to be inserted is locked to the adjacent bars by a pin 47. The air passages between the bars decrease in area in the direction of the fuel feed. The operating mechanism for the stoker ram is substantially identical with that described in Specification 287,748, [Class 51 (i), Furnaces and kilns, Combustion apparatus of]. Air supply, regulating.-The space below each half of the grate is divided by a wall, consisting of the rocking plate 69 and a pivoted flap 91, into two sections, so that air under different pressures may be supplied to different parts of the grate.

[Class 2 (iii)] Fuel hydrocarbon mixtures are prepared by reacting isoparaffins with olefines having not more than five carbon atoms or low-molecular weight polymers thereof at a temperature above 10‹F. and in the presence of a metal halide catalyst and of an alkyl halide. Isoparaffins specified are isobutane and isopentane, whilst ethylene, propylene, normal and iso-butylenes and normal and branched amylenes are referred to as olefines, together with polymers and copolymers thereof of low molecular weight; mixtures of hydrocarbons containing isoparaffins and olefines may also be used, e.g. partially dehydrogenated field butanes, and mixtures from catalytic or thermal polyrnerization and cracking units. The isoparaffin is preferably present in considerable molecular excess over the olefine, e.g. between 2 and 12 mols. of isoparaffin per mol. of mono-olefine. Catalysts mentioned are the halides of aluminium, zinc, antimony, tin, iron, nickel, tungsten, tantalum, zirconium, columbium, bismuth, beryllium, molybdenum, vanadium, titanium and thorium : also double salt complexes of aluminium halide and alkali metal halide including those of Specification 534,456. The catalysts may be mounted upon carriers either inert or activated with mineral acids or acid gases; carriers mentioned include silica gel, bauxite, kieselguhr. and the substance known under the Registered Trade Mark " Celite." Of the alkyl halides, mention is made of ethyl chloride, a propyl chloride, tertiary butyl chloride, and secondary or tertiary amyl chloride; the halide is preferably present in an amount between 1 and 15 per cent. of the weight of total feed. When double salt complexes are used as catalyst, high pressure and temperature conditions are employed, e.g. 400‹F. and 3,000 lb. per sq. inch.; otherwise temperatures of 15-80‹F. and atmospheric pressure suffices. The process may be effected continuously or in batches, and in the liquid or gaseous phase. A suitable apparatus is described and a table is given listing the data associated with a number of experiments. Specification 509,463 also is referred to.

[Also in Group XXV] A tubular rivet, for use in blind riveting in the construction of closed containers, repairing or patching motor car plating &c., comprises a screwed pin 1 with an integral or attached head 3 and with a flatted end 2 for holding the pin from rotating, a sleeve 4 with means 5 for centering it on the pin adjacent the head 3 but otherwise having clearance from the pin as shown in Fig. 1, and a nut 7 cylindrical at 11 to fit the hole in the plates 13 and correspond with the outer diameter of the sleeve 4 and head 3. The pin 1, head 3 and sleeve 4 may be integral. In this case the sleeve is first made as a radial enlargement of the head and after the pin has been screwed, the enlargement is rolled into parallelism with the pin to form the sleeve. The nut is coned at 10 and 12 and has a polygonal flange 9. After assembly and insertion as shown in Fig. 1 screwing up the nut on the pin expands the sleeve to engage and clamp the plates against the flange 9. The cone 10 expands the sleeve and the cone 12 forms a countersink in the plates displacing metal to interlock with the end of the sleeve. Ranges and preferred values for the conical angles are given. After setting, the excess length of the pin is cut off and the flange 9 may be filed or ground flush with the plates. In the case of a joggled lap joint, the space at the joggle may be filled with lead and the joint concealed by painting.
