Title: Improvements relating to cigarette lighters
Inventor: LOWENTHAL HANS
IPC: F23Q2/48
Filed: 1961-04-14
Abstract: 980,463. Cigarette lighters. COLIBRI LIGHTERS Ltd. Sept. 6, 1961 [April 14, 1961], No. 13581/61. Heading F4F. A cigarette lighter comprises a flint 8 slidable in a guide tube 9 and pressed against a flint wheel 6 by an abutment 10 attached to the outer end of a spirally coiled tension spring 17 which has its inner end free to rotate so that the coil unwinds as the abutment is moved away from the flint. The abutment 10 comprises a wire loop passing through diametrically opposite slots 12 in the guide tube 9 and pivotally connected to an L-shaped bracket 14 connected to the outer end of the spring 17 and having a hole through which slides a rod 20. To replace the flint the rod 20 is pulled down through a hole in the bottom of an inner casing 2 of the lighter and its head 21 engages the bracket 14 to move it to the bottom of the tube. Slots in the base of the inner casing allow the abutment to be moved aside clear of the guide tube 19. A base cover 24 is displaceable after loosening a screw 25. The described mechanism is incorporated in an automatic gas-burning lighter which comprises an outer casing 1, the partial inner casing 2 and a removable gas reservoir 3 with a burner 4 and a refill valve 5 covered by a spring door 37. Depression of a fingerpiece 29 gives access to the burner, rotates a lever 30 and the flint wheel 6 connected together through a ratchet, rotates levers 31 and 32 to compress a return spring 33 and pivots a lever 35 about a point 36 to open the burner valve. In a further embodiment Fig. 5, the abutment 71a has a wire loop bent into easily gripped shapes on either side of the guide tube 66 and is connected to the end of the spring 77 through a lug 76. The abutment is pulled down for withdrawal from the guide tube after an outer casing 52 is removed. This mechanism is incorporated in a non-automatic liquid fuel lighter which comprises the outer casing 52 closely fitting over an inner casing 51 containing the reservoir from which extends a wick 54 ignited by manual rotation of a flint wheel 64 and protected by a storm guard 57. A cover 58 is hinged to the inner easing 51 and is held closed over the igniting mechanism by a spring-loaded pivoted lug 60 which rocks out of engagement when the cover is manually rotated into the open position 58<SP>1</SP>. A modification incorporates a rod-like abutment which extends beyond the base of the guide tube to engage the spring. A further modification incorporates a spirally-coiled tension spring on each end of an abutment passing through longitudinal slots in the guide tube. The spring support pins may be coaxial with the flint wheel or at right angles to it. Specifications 980,461 and 980,462 are referred to.

Abstract: 974,077. Screw-and-nut gearing. ROTAX Ltd. April 19, 1961 [April 17, 1960], No. 13612/60. HeadingF2Q. [Also in Division B3] In ball screw and nut gearing of the type wherein the nut is formed in two sections 4, 7 which are angularly adjustable to take up backlash, as in Specification 822,582 the screwthread has flanks 2, 3 whose centres of curvature are spaced parallel to the screw axis so that they may be accurately ground to part-circular sections, the complementary flanks 5, 8 of the two nuts being also accurately ground. The radius of the part-circular cross-sections is equal approximately to that of the balls 9, which circulate in passages in the nut sections 4, 7. In manufacture, a helical groove is first roughly ground in the screw, and the flanks are then accurately ground in two separate operations, one for each flank, during which axial pressure may be applied to the grinding-wheel. The complementary operative flanks of the nuts 4, 7 (as shown, the inner flanks 5, 8) are similarly ground accurately, but the inoperative flanks (as shown, the outer flanks 6, 10) may be left in an inaccurate state to provide ball clearance.

Title: Improvements in secondary closures for bottles and like containers
IPC: B65D55/08
Filed: 1942-09-29
Abstract: <PICT:0606256/IV(a)/1> <PICT:0606256/IV(a)/2> <PICT:0606256/IV(a)/3> <PICT:0606256/IV(a)/4> <PICT:0606256/IV(a)/5> A shrinkable non-fibrous cellulosic tubular band for use as a secondary closure for a bottle or the like, comprises essentially an inner opaque cellulosic layer having superposed thereon an outer cellulosic layer of metallic appearance containing mica and a colouring matter.  The band may be of regenerated cellulose and the outer layer may contain mica and a yellow vat dyestuff or sulphur dyestuff.  The inner layer may contain titanium dioxide. As shown in Fig. 4, the tubular band comprises transparent portions 12, and portions 13 having a metallic appearance due to the presence in the outer layer of mica and a colouring matter and to the presence of an opaque pigment in the inner layer 14.  The band is shown in Fig. 6 applied to and shrunk around the top of a bottle already provided with a primary closure 21 and a seal stamp 22.  The transparent section of the film-like cellulosic band is positioned over the side portions of the seal stamp.  The band is applied when it is in the wet gel condition and as it dries it shrinks tightly on to the neck of the bottle.  The band may be made by cutting the desired length from a tube obtained by extruding cellulosic solutions from appropriately shaped nozzles. Concentric layers of viscose may be extruded and the extruded layers may be allowed to contact, and the resulting tubular structure is treated with a coagulating bath immediately after the layers have been joined and before substantial diffusion of the different types of viscose can occur.  The extrusion orifices may be arranged as indicated in Fig. 7, 8 or 9, in which clear viscose layers are being extruded from orifices 72, 82 and 92; opaque white layers are being extruded from orifices 74, 84 and 94; and layers containing mica and a colouring matter are being extruded from orifices 73, 83 and 93.  A yellow dyestuff is used when a gold appearance is desired, e.g. a yellow vat dyestuff such as 1-(11 : 91-isothiazolanthrone-21-carbonyl) - 6 - chloranthraquinone, or 1 - (11 : 91 - isothiazolanthrone - 21 - carbonyl) - amino-5-benzoylamino-anthraquinone.  Instead of adding colouring matter to the cellulosic solution, the regenerated cellulose tube, or the band cut therefrom may be dyed, e.g. with a yellow sulphur dyestuff such as the product of thionation of a mixture of meta-toluylenediamine and benzidine or the corresponding sulphur dyestuff from p-toluidine and benzidine.  If a silver appearance is desired, the outer layer containing mica may be coloured by means of a black pigment such as colloidal graphite, carbon black, or a black vat dyestuff.  Instead of regenerated cellulose, the band may be made of a cellulose ether or other cellulose derivative, coagulated from an aqueous or aqueous alkaline solution.  Specification 211,446, [Class 2 (ii)], is referred to.
