Abstract: 514,878. Electric incandescent lamps. AGHNIDES, E. Feb. 14, 1938, No. 4571. Void. Convention date, Feb. 12, 1937. [Class 39 (ii)] Anti - dazzle lamp bulbs, more particularly for use on motor cars, are so adapted that the greater part of their illumination is directed upon the near side of the road. The result is preferably attained by the provision of an internal screen suitably mounted within a bulb of either the single or double filament type. Alternatively, a bulb with a single unscreened filament is mounted within a reflector which has been rendered non- reflecting over a sector 90-135 degrees. The Figure shows a cross-section of a bulb provided with a screen 3<1> parallel to an axial filament 2<1>, the shape of the screen being such that it shuts off light rays from one of the lower quadrants of the reflector within which it is mounted. The upper edge of the screen may extend into the adjacent quadrant, to thereby include an angle of 135 degrees. If the lamp is of the double filament type the filaments are arranged along a line at an angle of 45 degrees to the horizontal plane. It is also stated that a double filament lamp of known type, with a screen disposed beneath the auxiliary filament, may be turned through 90 degrees from its normal mounting position, either by so adjusting the socket or fixing the bayonet pins in different positions, so that when mounted in a headlamp the screen is to the left or right of its co-operating filament.

Abstract: 948,916. Xerographic apparatus. RANKXEROX Ltd. Feb. 10, 1960 [March 4 1959], No. 4738/60. Heading G2H. [Also in Division H5] The apparatus includes a drum 10 with a photo-conductive layer on its outer face, or a light receiving surface on a conductive backing, the drum being mounted in conjunction with a motor 12 to rotate in a clockwise manner at a constant rate. Charging apparatus 13 which includes a corona discharge array of electrodes is used to establish a uniform charge distribution on a portion of the drum surface before it passes through an exposure station comprising an optical projection system 14, used to project a line copy image on to the p-c. surface. Adjacent to the exposure station is a developing station 15 in which a bucket type conveyer driven by motor 18 carries developing material to the upper part of the housing where it is cascaded down over a hopper shoot 21 on to the drum. In this manner toner particles are removed from a carrier component of the developer and deposited on the drum to form powder images. The partially denuded particles, and the excess pass into sump portion 16 of the housing 15. The supply of developer may be replenished, as required, from side shoot 22 containing toner particles 23. The toner particle image is then transferred to a support surface web 25 carried between spools 26, 27 as shown in the drawing, guide rolls 33, 34 serving to hold the web and drum surfaces in contact. The web is driven by means of motor 31, and particle transfer from the drum to the web is facilitated by an electrostatic transfer unit 35 of similar construction to unit 13 used to attract the particles on to the web. Any residual powder on the drum after transfer is removed by brushes 36, and any residual charge is dissipated by lamp 38. The transferred images on web 25 pass under an electric heater 40 where the toner particles are fixed on to the web surface.

Abstract: 1,022,467. Internal shoe drum brakes. AUTOMOTIVE PRODUCTS CO. Ltd. Feb. 3, 1965 [Feb. 6, 1964], No. 5095/64. Heading F2E. An internal shoe drum brake comprises a pair of brake shoes 11 and 12 bearing against a fixed abutment 13 between one pair of adjacent shoe ends and having applying means in association with automatic wear adjusting means between the other pair of adjacent shoe ends. A wheel cylinder 18 is slidably-mounted on a backplate 10 in a housing 17 which is itself slidablymounted on the backing-plate, the closed end of the cylinder having an abutment 26 for the shoe 12. As illustrated in Figs. 2 and 3 (not shown), a piston 19 in cylinder 18 has a coaxial bore which slidably-receives a first stem part 27 of a thrust and wear - adjustment member threadedly-interengaged with a peripherallytoothed, second disc part 28, said first part abutting the shoe 11 and said second part abutting the piston. On supplying pressurized liquid to the cylinder, piston 19, through the thrust member, urges shoe 11 into engagement with the brake drum 14 and cylinder 18 reactively slides to the right to apply shoe 12. The housing 17 has axial-extending parts 30 abutting the disc 28 and pivotally mounts a cranked adjusting lever 35. One arm 35 of this lever forms a pawl member engaging the teeth on the disc, and the second arm is connected by a rigid link 36 and a tension-spring 37 to shoes 12 and 11, respectively. A mechanically-operated applying lever 32, linked to a hand brake or similar device, is pivoted on the shoe 12 at 31 and abuts the housing 17 at 26. On operation of the applying lever, shoe 12 is directly applied to the drum and thrust is transmitted through the sliding housing, extending parts 30 thereon, and the two-part thrust and adjustment member 27, 28 to the shoe 11. Simultaneously, relative movement between the housing and shoe 12 rocks the adjusting lever about its pivot on the housing. If sufficient wear has taken place for the pawl arm to engage a fresh tooth on disc part 28, said disc will be rotated relative to the stem part 27 to increase the effective length of the thrust member on return of the adjustment lever by spring 37 when the brake is released. In modified embodiments, Figs. 4-6 (not shown), the adjusting lever is T-shaped, one arm of the T being connected to shoe 11 by spring 37 and the other arm being connected to shoe 12 by a rigid link and resilient means 44 or 45. Wear adjustment in these embodiments is made on brake application by the applying lever, said resilient means preventing damage to the parts in the event of friction in the screw-threads of the thrust member parts 27, 28 causing excessive loading of the rigid link.
