Abstract: 1414839 Packaging ampoules GIRAUDET EMBALLAGES 12 Nov 1973 [13 Nov 1972] 52416/73 Heading B8C A support for ampoules comprises a base 14, 16 and two parallel, prismatic stands folded up from opposite marginal portions of the base, at least one stand having openings 12 for receiving the ends of a set of ampoules and being held erect by connector lugs 8 which are integral with the associated margin 16 of the base and extend below the stand through the bases of the openings 12. Further lugs are formed integrally with the central portion 14 of the base when the openings 12 are cut. These lugs lie beneath the connector lugs 8 and assist in holding the stands erect. The sides of the lugs are contoured to limit their movement through the hollows. The second stand may take the form disclosed in Specification 1,414,433. Before insertion of the ampoules, each stand is partially erected so that the ampoules may be lowered into the article-receiving openings without deforming the support. Finally, the connector lugs 8 are pushed fully through the openings. A plurality of support blanks may be formed as a single unit.

Abstract: 1,129,100. Gas lighters. A. AFFOLTER. 15 Dec., 1965 [19 Aug., 1965], No. 53287/65. Heading F4F. A gas lighter comprises a cylindrical casing 1 formed with a fuel reservoir 2 and a central peg 3 through which the fuel passes up a nylon wick 19 to a valve 14 secured in its upper end. The valve is formed with a screw threaded axially adjustable inner sleeve 21, Fig. 3 (not shown) which compresses a porous pad 20 within the valve. To open the valve a needle 28 is raised against the action of a spring 29, Fig. 3, by a cross-member 35 of a control member 34 engaged under a split ring 39 mounted in a groove on the needle. Clips 36, 37 of the control member engage the sides of the casing 1 and the cross-member 35 is lifted by thrusting upwards clip 36 until its lower end engages a shoulder 41 of a bearing face 6 (dot-dash lines). Pressure on the clip 37 will return the control member to its inoperative position. A cap 8 rotatable with respect to the casing carries a flint wheel 10 and a flint tube 11 which projects into the annular space between casing 1 and peg 3 and passes through a disc 23 engaged on a head 24 solid with sleeve 21. Rotation of the cap alters the compression of the porous pad thereby varying the flame height. The valve 14, Fig. 3 (not shown) comprises an outer 15, the base of which is provided with an off-centre hole 18, and in which is located the porous pad 20. Inner sleeve 21 screw threaded into the outer sleeve is formed in its base with a nozzle 25 on which is located a rubber pad 31 compressed by the burner 28. Spring 29 acts on the burner so as to keep the nozzle 25 closed until control member 34 raises the burner to allow gas to flow into the burner passage 32.

Abstract: 1,171,936. Vehicle headlamps. PROJECTEURS CIBIE. 2 Dec., 1966 [14 Dec., 1965; 18 Feb., 1966; 29 March, 1966], No. 54098/66. Heading F4R. [Also in Division F1] The orientation of the headlamps of a vehicle is controlled automatically, e.g. to compensate for unequal loading of the front and back axles, by two mechanical linkages, one at the front and one at the back of the vehicle and each acting on respective lever, displacement of the end of which operates a respective hydraulic transmitter, the transmitters being connected in opposition to an hydraulic circuit operating on a device acting directly on one headlamp and also on a connecting circuit therefrom operating the second headlamp. Movements of the rear wheels AR are transmitted by a lever 8 and link 11 to a lever L 1 , movement of which acts on a flexible membrane 1d and a variable volume hydraulic chamber 1c. Similarly, movement of the front wheels AV acts through lever 12, link 13 and lever L 3  on the flexible membrane 3d of a variable volume hydraulic chamber 3c. The chambers 1c, 3c are connected in opposition to an hydraulic transmission circuit 2 terminating in a chamber 5a having two flexible membranes 5d, 5e between which is a piston, movement of which causes movement of the headlamp P 1  by means of a rod 16. An hydraulic transmission circuit 6 connects the space between the membrane 5e and the end of the chamber 5a to a chamber 7a acting through a membrane 7c and rod 18 on the headlamp P 2 . Variation of the operation of the system as a result of changes on external temperature may be compensated for by connecting to the circuit 2 a cylindrical plastic envelope within which is enclosed a metallic cylinder which expands less with increased temperature than does the envelope.

As shown, the strip 2 is wound from a reel 1 on to a stationary mandrel 3 with adjacent turns of the strip overlapping, and is then drawn axially, without rotating, through complementary rotary threaded dies 4, 5 to form a helical rib 8. The strip 2 then passes through a further rotary die 6, which shortens the pitch of the rib 8 to axially compress the tube, a stationary mandrel 12 with serrations 13 engaging the tubing 10 within the die 6. The tube then moves forward between four equi-angularly spaced rollers 7 which are mounted, for rotation, on a fixed framework, not shown, and deform the rib 8 inwardly along lines parallel to the axis of the tube to secure the overlapping portions of the strip.
