Abstract: 870,482. Mounting light fittings. SWIVELIER CO. Inc. March 24, 1960 [May 7, 1959], No. 10522/60. Class 75(3). [Also in Group XXV] A recessed lamp fixture assembly comprises a box 11 haying an open side, a face plate 16 forming a closure for the open side a joint means 17 secured to the face plate at one side thereof facing the inside of the box, a lamp shade 19 disposed on the other side of the face plate and secured to the joint means; a recess defined by a formation in the face plate the joint means being constructed to permit the shade to enter in and withdraw from the recess. A bracket 100 secured to a wall or a recess in the wall 13 mounts the box which mounts the face plate. A recess in the face plate partly encloses the lamp when it is in the withdrawn position. The lamp pivots outwardly on a sphere 33 either integral with the face plate or mounted on a horizontal pivot 34 non rotatably mounted in brackets secured to the face plate and rotating through nearly 360 degrees on a tubular member 31 when the lamp is out of the box. The sphere seats in the closed end of a tubular member 30 housing a friction member 49 which presses against the sphere and is spaced by a spring 47 from another friction member 48 which presses against the tubular member 31. A clamp 32 joins the tubular members and a stop on the member 31 contacts a stop on element 40 of the clamp to limit the rotation of the lamp. The end of the member 31 has two wings which pass through an aperture in the shade and mount the pivots on a bracket 20 secured inside the shade and connected to the lamp socket holder 21. One part of the clamp securing the two tubular members together may be moulded to the member 30 the other part of the clamp being secured thereto.

IPC: C03B7/10
Abstract: 105,564. Tucker, O. M., and Reeves, W. A. April 10, 1916, [Convention date]. Delivering molten metal.-In order to obtain a charge of glass, molten metal is allowed periodically to extrude itself into space, through an unthrottled aperture 2 in a tank &c., in the form of gobs or globules, which, when of the required size, are cut off, the glass between the severing operations is supported independently of the severing-means. The severing is effected preferably before a defined neck is formed. The rate of extrusion may be regulated by means of a heating flame burning in a cup or receptacle 6 having an inlet 24 to admit combustible fluid which passes through apertures 23. The cup is brought under the orifice 2 after the glass has been severed and may be gradually lowered as described in Specification 109,782. The flame reheats and reforms the cut end of the glass. The knives 4 may be tilted and guides 5 then, as shown in Fig. 2, direct the falling charge.

IPC: H02K5/06
Abstract: 105,634. Mortley, G. E. April 27, 1916. Casings.-The casing of a dynamoelectric generator for use on an aeroplane or airship is constructed with an ovoid or streamline form so as to reduce air eddies to a minimum. The casing is preferably in two halves joined on a plane at right-angles to the armature axis by lugs or bolts by which it may also be secured to the fuselage of the aeroplane. The commutator E is of conical form and the brush-holder F is set at an angle to the armature axis. Openings are provided at each end of the casing to allow air currents to pass through, the armature and field magnet laminations being formed with ventilating passages. The generator may be driven directly by an air-screw or other source of power, or a governor may be interposed between the generator and air screw in order to maintain the generator output constant. The front end of the casing proper may be truncated, in which case a nose piece surrounding the governor and revolving with either the air-screw or the spindle is employed to complete the stream line form. The armature or the casing may be driven by the air-screw.

Abstract: 456,279. Photographic sensitive materials incorporating yellow filter dyes. KODAK, Ltd., Kingsway, London.- (Eastman Kodak Co. ; 343, State Street, Rochester, New York, U.S.A.) April 5, 1935, No. 10601. [Class 98 (ii)] Azo dye containing a carboxyl group but free from nitro, amino, or sulpho groups are used as yellow filter dyes in photographic sensitive materials. The yellow dye may be present in the silver halide emulsion layer or in a layer adjacent thereto, and the emulsion layer may contain as a colour sensitizer a cyanine dye. With photographic sensitive material having at least two differently colour sensitized emulsion layers, the yellow filter layer may be over the emulsion layer nearest the support, or the yellow dye may be uniformly dispersed in the emulsion layer farthest from the support. Photographic sensitive material may have three diiferently colour sensitized layers on one side of a support and separated by inert clear gelatine layers, one of the gelatine layers having the yellow filter dye uniformly dispersed therein. Suitable azo dyes are benzeneazo benzoic acid, Diamond Yellow G, and the azo dye obtained by coupling two molecules of salicylic acid with one molecule ofp-phenylenediamine. Azo dyes containing as additional nuclear substituents alkoxy, chlorine, and bromine groups may also be used. Specifications 441,325 and 444,198 are referred to. The Provisional Specification describes also the use of azo dyes containing one or more hydroxy groups. Dyes specified are benzeneazophenol, oc-naphthaleneazophenol, benzeneazoresorcinol, 1-hydroxy-4-(p-hydroxyphenylazo) P - naphthalene, benzeneazocresol, and pyramidol Brown. The support for the threelayer sensitive material may be cellulose derivative, glass, or paper.

Title: Improvements in or relating to compound internal combustion engines
IPC: F02B41/06
Filed: 1948-04-19
Abstract: 646,092. Four-stroke engines. NACCACHE, A. April 19, 1948, No. 10783. Convention date, Feb. 13. '[Class 7 (ii)] In a compound engine in which the firing cylinder 9 operates on a four-stroke cycle and the expansion cylinder 68 operates between the expansion and exhaust strokes to compress the charge of the cylinder 9, this charge passes immediately after compression through heat exchangers 5, 6 and through spaces 4 in the pistons. A delivery valve 56 leads by a passage 57 to the heat exchanger 5 and a passage 13 leads from the heat exchanger 6 to an inlet valve 14. A fuel-injector 69 is placed in a passage 54 which leads to the expansion cylinder and is controlled by a valve 53. In Fig. 8 two pump pistons 70 supply gaseous charge and scavenging air alternately to two highpressure cylinders 9 which feed a common low-pressure cylinder 72, an additional heat exchanger being provided for the scavenging air. In a compression-ignition engine both pistons 70 supply charging air. In a further modification the pump cylinders 71 are omitted, and the high pressure cylinders each have two diameters and pistons compressing a gaseous charge in the annular spaces thus formed, which are controlled by non-return valves or pistoncontrolled cylinder ports. As shown in Fig. 20, the compressed charge is first delivered to a heat exchanger 177 and it is then further compressed in an annular space around a stepped expansion piston 1 before passing to the heat exchanger 5 and through ports 7 in the pistons to the other heat exchanger 6.

Title: Improvements in insecticides
Filed: 1925-04-29
Abstract: 257,644. Marks, E. C. R., (Rubber Service Laboratories Co.). April 29, 1925. Insecticides.-An insecticide is produced by incorporating a thiourea, for example a substituted thiourea, such as thiocarbanilide, with a protective colloid, such as flour, gelatine, glue. Irish moss. agar-agar. soap, or gum tragacanth, in the dry state, and then gradually adding water so as to produce a colloidal suspension. A solid substance having insecticidal properties, such as sulpnur or lime, may also be incorporated. In an example, 4 ozs. of finely divided thiocarbanilide are intimately mixed with one ounce of flour and 2-4 ozs. of finely divided sulphur, and a small quantity of water is added from time to time to the mixture with stirring so that a stiff mass is first produced, the materials being thoroughly wetted. The mixture is then diluted by the addition, in all, of 3 gallons of water and used for spraying plants or trees. Up to 3000 parts by weight of water may be added to the mixture. Lime may be used in place of the sulphur. Copper sulphate or carbonate may also be added where the mixture is to be applied to potato or other plants subject to blight.
