Title: Improvements in relation to the automatic charging of electric storage batteries
IPC: H02J7/04
Filed: 1933-09-29
Abstract: 411,348. Battery charging. BRITANIA BATTERIES, Ltd., 233, Shaftesbury Avenue, London.-(Assignees of Accumulatoren-Fabrik Akt.-Ges. ; 3, Askanischer Platz, Berlin.) Sept. 29, 1933, No. 26838. Convention date, Sept. 29, 1932. [Class 38 (iv).] In an arrangement for controlling the charging of storage batteries a relay, having a current winding only and adapted to operate when the charging current falls to a predetermined minimum value such as the value incident to gassing point or the value attained when 95 to 100 per cent of the electricity previously discharged has been recharged into the battery, depending on the method of charging used, is arranged to release an integrator or clock mechanism which cuts off the charging current when the battery is completely charged.

Title: Improvements in kinematographic apparatus
IPC: G03B21/32
Filed: 1924-11-10
Abstract: 245,882. Lloyd, H. H. Nov. 10, 1924. Kinematograph apparatus.-In apparatus comprising means for reversing the film movement, the reversing means is controlled by the tension of the film; in apparatus comprising also a laterally movable mask and lens, for use in exposing or projecting different longitudinal strips of the film, the movement of the mask and lens may be effected simultaneously with the reversal. As shown in Figs. 1 and 2, pulleys 18 carried on pivoted arms 19 engage the film 13 between sprockets 12 and the reels, the arms being normally in the position shown in continuous lines, and the film ends being secured to the reels. Two rocking arms 21 carry a bar 17., and may be engaged by studs 20 on the arms 19. When the film lias completely run off the upper reel, the upper arm 19 is lifted and the bar 17 is lowered, the bar 17 being raised in a similar manner by the lower arm when the film has completely run off the lower reel. A link 22, Fig. 3, pivoted on the bar 17, has a pin 23 engaging a slot 24 in a spring controlled plate 25 pivoted at 26, and causes the plate 25 to assume the position shown in continuous lines when the bar 17 is lowered, and the position shown in broken lines when the bar 17 is raised. A slot 31 in the plate 25 engages a pin 30 on a frame 15 and moves the frame laterally in accordance with the position of the plate 25. The frame 15 carries a mask and a lens holder 14, and is normally locked in position by the engagement of the bar 17 in grooves 16 in the frame. Lateral movement of the frame 15 operates a lever 43 to move a clutch. member 41 in a reversing gear between the driving spindle 33 and the sprocket spindle 40. In a modification, Fig. 6, pivoted arms 58 carrying pulleys 57 are connected by a link 61. Tightening of the film moves one of the arms and lowers through a link 63, a clutch element 64 rotatable with, but movable longitudinally on, a rotating shaft 65. The element 64 then engages a clutch element 66 which does not rotate with the shaft 65 and is not axially movable thereon, thus causing a temporary rotation of the element 66, and operating, through an arm 67 and lever 68, to move the mask and lens holder 54 and change a reversing gear on the sprocket shaft 74.

Abstract: 418,618. Roller blinds. FEHER, A., 176, Th÷k÷ky Ut., Budapest. Oct. 4, 1933, No. 27321. [Class 52 (v).] A device for drawing and fixing roller blinds comprises a common dust proof casing containing the locking device and the winding spring which are connected by a reducing toothed wheel transmission. The casing comprises two parts b, c<1> with a front wall c and a detachable rear plate. On the inner side of the front wall c of the casing c<1> is fixed a ratchet wheel n having four teeth. A central bore supports the shaft 4, 6 which also forms a wheel 5 of the transmission gearing and upon the shaft is mounted a pawl disc h with pawls j engaging the teeth of the ratchet n. The pawl disc h has an aperture corresponding to the shape of the toothed wheel 5 and is fixed thereon by a pin 5<11>. A screw 14 passing through a tubular axle secures the casing to the wall and also supports the large toothed wheel 2 and the winding spring o. One end 10 of the latter is held in a slit 11 in the toothed wheel 2, the other end being attached to a tubular projection 7 on the end wall. A partition 9 is arranged between the toothed wheel 2 and the winding spring o and a cover plate 8 is fixed on the projections 7. The toothed wheel transmission enables shorter springs to be used and when the blind roller is rotated quickly the pawls j swing out and do not engage the ratchet teeth. The roller is journalled on the square end f of the shaft 4 and the other end may have a journal f<1> which is held in a bearing comprising two plates u, v, sliding one within the other. The journal f<1> is introduced into a horizontal slot x in the supporting plate u, and the other plate v is dropped to retain the journal within its vertical slot z.

Abstract: 784,625. Making springs; altering physical properties. INSTITUT DR. ING RHEINHARD STRAUMANN AKT.-GES., and STRAUMANN, F. Oct. 3, 1955 [Oct. 2, 1954], No. 28088/55. Classes 83 (2) and 83 (4). A method of producing a non-magnetic thermally compensated spring from a non-ferromagnetic material which crystallizes in the cubic system and shows an anomaly of the thermo-elastic coefficient as well as a thermoelastic anistropy comprises homogenizing and quenching the material and then treating it so as to produce the required orientation of crystal structure in the finished products. In an embodiment a wire or ribbon of a non-magnetic metallic material, e.g. #-brass, is homogenized at a temperature not exceeding 1200‹ C. and then quenched, cold drawn and/or flat rolled to a total reduction in cross-section not exceeding 95 per cent. Finally the texture is improved by recrystallization at approximately 500‹ C. The above treatment brings the 110 or 100 direction parallel with the longitudinal axis of the wire or ribbon besides imparting to the spring material a low thermo-elastic coefficient due to the formation of a super-lattice. Specification 733,510, [Group II], is referred to.
