[Class 39 (ii)] A lamp adapted particularly for air raid precaution purposes is provided with two incandescent filaments 3, 4 of different luminosities which can be switched on alternatively, within a bulb 1 which is partly covered with an opaque or substantially opaque layer or layers 2, the filament 3 which is of higher luminosity for " reduced lighting " purposes being so arranged within the bulb that the angle of spread of the beam of light furnished thereby is greater than that of the beam furnished by the filament 4 of lower luminosity which is for " black-out " purposes. As shown, the filament 4 is located between the stem tube 13 and filament 3, the latter being nearer to the transparent end portion of the bulb. A light filter 5 consisting of a disc of blue glass is mounted on the rod carrying the filament supports, between the filaments 3, 4. Alternatively or additionally, the bulb 1 itself may be made of blue glass. The inside of the bulb is preferably frosted, and the coating 2, which may be black or dark blue, may be applied by spraying. Switching - mechanism of known type, e.g. a movable contact arm operated by chains 11, 12, may be located within the head 6 of the lamp. The bulb may be made of tubular shape, with or without a gas filling, and the colour of the coating may be modified to adapt the lamp for photographic or laboratory purposes.

Abstract: 1,192,331. Jointing. HAYDEN-NILOS Ltd. 24 Dec., 1968 [5 Feb., 19681, No. 5633/68. Heading B3U. A tool for securing two or more elements together by a bolt F and collar E comprises means 5 for drawing collet jaws 26 away from a swaging nose 34 and a spring 23 for urging the collet 26 towards an annular projection 33, which opens the collet 26 when it is moved back towards the nose 34 after the collar E has been swaged into the recesses of the bolt stem. Plate elements B, C are secured to a belt D by placing the swaging nose 34 of the tool on the collar E and rotating a driving member 11 by a handle 19. A tubular insert 5 in screw-threaded engagement with the member 11 is thereby raised causing its lower tapered inner surface 24 to urge the collet jaws 26 into engagement with the bolt stem F and to draw them away from the nose 34. The belt D is compressed between the plates B, C and the collar material E is forced into the screwthreads or circumferential grooves of the stem F by the swaging nose 34 to secure the collar E to the stem F. After swaging, the tubular insert 5 is returned to its initial position by the handle 19, the spring 23 pressing the jaws 26 to the annular projection 33 to release them from the stem F. After withdrawing the tool, the surplus stem length is cropped by applying the bored end 39 of the handle 19. In an alternative embodiment (Fig. 5, not shown), the tubular insert 5 is formed with a piston (40) which is moved upwards by an hydraulic medium.

Feb. 22, 1934, No. 5888. Convention date, Feb. 22, 1933. [Class 40 (iii)] In a cathode-ray television-transmitting system employing an oscillograph screen which produces fluorescent and phosphorescent light the fluorescent component which is employed as the scanning light is separated from the phosphorescent or after-glow component which is eliminated or reduced. The spectral maximum of fluorescence normally occurs displaced towards the shorter wave length portion of the spectrum as compared with that for phosphoressence, and an appropriate filter is included between the oscillograph screen and a photoelectric cell having maximum sensitivity in the corresponding portion of the spectrum. When the fluorescence occurs in the ultra-violet portion, optical apparatus and an oscillograph screen of quartz may be employed in conjunction with a sodium photo-electric cell. When the subject of transmission is a film the thickness of the coating emulsion and of the film itself may be less than normal to increase its transparency to ultra-violet light.

Abstract: 1,099,202. Ball joints. CAM GEARS (CLEVEDON) Ltd. Sept. 2, 1966 [Feb. 10, 1966], No; 5969/66. Heading E2F. A ball joint, of the type in which a ball-head on a ball pin is retained for swivelling movement in an outer housing having an open mouth through which the pin shank projects, is composed of two complementary metal pressings 3, 4 which are assembled to provide a pre-loaded fit around the ball-head 2 with an interposed liner or layer of hard-wearing low friction synthetic plastics bearing material (e.g. nylon) 5 by means of permanent deformation at the time of assembly of said bearing material or of a shim disposed between facing flanges of said metal pressings and/or of the metal pressings. Tht joint is conveniently provided with a flexible dust sleeve 9 secured to the housing by a clamping plate 10. In an embodiment of the invention, the top housing 3 is formed with a number of slots introducing a spring effect and the bearing material is limited to the lower housing. In another modification, the bearing material is extended to completely cover both the inner and outer surfaces and edges of the two pressings. The pre-loaded fit between the pressings and ball-head is achieved by having the bearing material in a semi-fluid or only partially set condition on assembly and/or by final deformation of. the pressings around the ballhead by means of dies. Alternatively, this is achieved by inserting between the facing flange surfaces on assembly a synthetic plastic shim having a lattice pattern or a series of protuberances on one or both faces, so as to deform the flow into the lattice indentations or spaces between the protuberances when the pressings are brought together under heat and pressure.
