摘要： 714,078. Electrolytic surface treatment of aluminium. EVER READY CO. (GREAT BRITAIN), Ltd. Aug. 27, 1952, [Sept. 24, 1951.] No. 2334.4/51. Class 4I. Articles of aluminium or an aluminium-rich alloy are polished by immersion in a heated electrolyte comprising phosphoric acid, sulphuric acid, a phosphoric acid ester of a polyhydric alcohol or a salt thereof, and water; after a period, during which etching is effected, the article is connected as anode to direct current voltage. Suitable proportions for the electrolyte are 45-80 per cent by weight of phosphoric acid, preferably orthophosphoric, 5-20 per cent of sulphuric acid, and 1-5 per cent of the phosphoric acid ester or salt. The latter constituent may be glycerophosphoric acid or its sodium or potassium salt. The period before passage of current may be 3o-6o seconds, the bath temperature 70‹-90‹C. and the anode current density 100-180 amps per sq. ft. The anode support may be reciprocated to agitate the electrolyte. The cathodes may be of lead or graphite and are preferably of area substantially greater than the projected area of the article under treatment. The article after electrolytic treatment may be washed in water containing a wetting agent, and a thin surface film present thereon removed by immersion in a solution of chromic and phosphoric, or chromic and sulphuric, acids or of salts of these acids. The articles may then be anodized in a chromic acid or sulphuric acid bath to produce an opaque or transparent coating and the coating dyed and/or sealed. An impact-extruded or deep-drawn article e.g. an electric torch case may be subjected to a light mechanical polishing before the electrolyte polishing.

摘要： 612,920. Battery lamps. EVER READY CO. (GREAT BRITAIN), Ltd., GLAZE, N., and LEE, T. W. June 6, 1946, No. 17223. [Class 39 (ii)] The handle of a battery lamp comprises two similar members each forming a resilient loop adapted to overlie the rectangular casing each at one of two opposite sides and to overlap a part of the front of the casing. Each member pivots in a pair of aligned sockets at the back of the casing to occupy the position shown in Fig. 4 in which the portions 21 may be gripped in one hand. The sockets are humped as at 19 to lock the members in their alternative positions and are preferably carried by a plate 16 fixed to the back of the casing. To provide for securing the lamp on a waist belt a spring tongue 26 is secured to the casing or to the plate and stepped tongues 27 are formed longitudinally on the plate after slotting it centrally. A resilient plate 28 is fixed to the casing between and behind the tongues 27 whereby the casing may be secured on a cycle bracket or the like. To enable the lamp to be suspended on a button, a loop with a screw portion 32 may be carried in a socket 29 with humps to hold the the loop in an extended position and in the position shown. The switch 15 is arranged in a sloped portion 12 at the top of the casing which may have a hinged front retained by sliding catches operated by a knob 37.

摘要： 612,537. Battery lamps. EVER READY CO. (GREAT BRITAIN), Ltd., and GLAZE, N. May 7, 1946. No. 13839. [Class 39 (ii)] To obtain a metallic connection between the battery and the anodized aluminium casing of an electric torch the anodizing is removed, as by a reamer, from the rear end of the casing and the screw cap comprises a coil spring arranged to rotate therewith and contact the base of the battery, a contact member being associated with the outer convolution of the spring to engage the end of the casing. Where the spring is friction tight in the cap its end may be off set as at 6, Fig 1, to cross the end of the case at an angle. A metal plate secured in the cap may have peripheral tongues 6, Fig. 4, inclined inwardly to the axis of the cap, at least one of which clips over the spring. In another form radial tongues are each bent upwards and downwards so that at least one may engage over the spring while the outer portions of all engage the edge of the casing.

摘要： 483,065. Retractive switches. EVER READY CO. (GREAT BRITAIN), Ltd. July 2, 1936, No. 18427. Void. Convention date, Aug. 10, 1935. [Class 38 (v)] A switch, particularly suitable for a battery lamp, comprises co-operating contacts mounted in a housing, and means for moving one of the contacts into engagement with the other, said means comprising a finger-piece that is both rockable about an axis and bodily translatable. In the construction shown in Figs. 1 and 2, the contacts 10, 12 are enclosed in a housing 16 secured to a flashlamp casing 18, the contact 10 being in the form of a resilient switch-blade, while the contact 12 normally occupies a position in the path of the contact 10, but can be moved out of this path, to render the switch inoperative, by means of a button 34 slidably mounted in the housing. The switch is operated by a finger-piece 14 having a central portion 36 of circular outline, the outer part of which extends through an opening 38 in the housing, while the inner part engages the switch-blade 10, and arcuate portions 40 on each side of the central portion. The inner portion of the finger-piece engaging the switchblade is formed with a depressions 44 co-operating with a projection 46 on the switch-blade. The contacts 10, 12 can be brought into temporary engagement by depressing the fingerpiece, or bv rotating the finger-piece so that the projection 46 leaves the depression 44 and engages the surface of the portion 36, the contacts can be held in engagement with each other. To prevent excess pressure on the finger-piece from injuring the switch, the inner movement of the finger-piece is limited by the engagement of the arcuate portions 40 with the sides 54 of a groove 52 which receives the contact 10. In a modification, the fingerpiece is provided with two depressions, one deeper than the other. When one projection on the switch-blade engages the deeper depression, the switch cannot be closed by depressing the finger-piece, but by rotating the finger-piece so that the projection engages the surface of the finger-piece between the depressions, the switch can be held in the closed position. In another construction, Fig. 5, the movable switch-blade 72 is carried by a stud 80 mounted in a slot in the housing 74, the switch-blade being provided with a depending ear 84 adapted to make contact with the conductor 70, which is insulated from the casing. The switch may be closed by depressing the finger-piece 88, or it may be closed and held in the closed position by rotating the finger-piece, until a rib 96 on a cam 94 engages a depression 98 in the switch-blade. The switch can be rendered inoperative by sliding the switch-blade to the left by means of the stud 80. In another construction, the finger-piece is provided with a triangularshaped cam, the apices of which are adapted to engage the depression in the switch-blade to hold the switch in the closed position. In the construction shown in Fig. 11, the fingerpiece 131 carries cams 136 and bosses 138, the latter being adapted, in certain positions of the finger-piece, to engage abutments 140 on the base 142 and prevent closure of the switch. The finger-piece is mounted on trunnions slidable in vertical grooves in the housing 127, and has three pairs of operating positions, i.e. two positions in which the switch is closed. two in which it can be closed by depressing the finger-piece, and two positions in which closure of the switch is prevented. In a modification of this construction, the finger-piece is provided with an additional pair of lugs which, in the inoperative position, engage notches on depressions in the switch-blade to lock the latter in this position. A manuallyoperated actuating member is provided to depress the switch-blade and unlock the switch. In another modification, Fig. 20, the fingerpiece 184 is mounted on a trunnion 188 in an opening in the housing 172, and is formed with a cam-shaped end 192. In the position shown, closure of the switch is prevented, but by moving the finger-piece to the position in which the flat surface 192 of the cam engages the switch-blade 166, the switch can be closed by depressing the finger-piece. By rotating the finger-piece still further, the inner end '193 of the cam engages the switch-blade and holds the latter in the closed position. The finger-piece may be provided with projections adapted to engage lugs on the housing to latch the switch in the inoperative position.
