    • A tamper evident closure device comprises a screw-threaded inner cap member 10 and outer cap member 14, which rotates freely in the unscrewing direction without engagement of the inner cap and has an aperture, covered by a tamper evident tear strip 27 which must be removed or destroyed to permit unscrewing of the closure as a whole unit. The inner and outer cap mutually engage, either by insertion of a tool into a slot in the upper surface of the inner cap or by depression of the outer cap, for unscrewing of the closure. The tear strip may be a self adhesive label which may comprise a projecting tab which can be removed to fully expose a portion of the inner cap member. The label may comprise a main portion and a removable portion over the aperture with lines of weakness between the two, may be free of adhesive, may be circular and adhered concentrically on the outer cap member, and may carry opening instructions and/or a hologram. The inner and outer cap members may be of different colours. Fingers 22 on an inside top surface of the outer cap and dogs 23 on the top of the inner cap engage to allow the cap to be screwed on, and slip in the opposite direction to prevent unscrewing. In a separate embodiment, a one piece moulded closure cap has a depending cylindrical skirt (12, fig.3) and a resilient flexible annular seal (30, fig.3) on the internal surface of the top of the cap.

    • 573,288. Tanks. NAPIER & SON, Ltd., D., COWDREY, C. L., and CHURCHILL, J. A. March 22, 1944, No. 5327. [Class 69 (i)] Relates to tanks subject to temporary inversion, such as fuel or oil tanks for aircraft, and to means for ensuring uninterrupted supply therefrom. The tank comprises a main, normally uppermost, part A provided with a fluid inlet G and connected to a sump B with an outlet C, the parts A, B being preferably formed separately and connected to form a neck E in which is held a rubber &c. ring F forming a valve seat. Within the part A is a spider H supporting a guide sleeve H in which is slidable a tube J provided at one end with a lead &c. valve head K adapted to co-operate with the seat F and preferably provided at the other end with a dished plate M which may have apertures M ; a weighted collar such as N may be provided adjacent the plate M. With the tank in normal position, Fig. 1, the fuel &c. passes freely around the tube J ; when the tank is inverted, the tube J slides down and the valve K engages the seat F, the fuel &c. then passing up through the tube J.

    • 453,894. Two-stroke - cycle engines. CHAMIER, J. A., Aldwych House, Aldwych, and JONES, G. F., 10, Langbourne Avenue, West Hill, Highgate, both in London. March 22, 1935, No. 9045. [Class 7(ii)] Sets of L-shaped pistons work in blocks of cylinders at right angles to each other, the cylinders of each block being rotatable about the axis of the block, and the two blocks being geared together at their adjacent ends by bevel wheels 4. Each piston consists of a pair of heads 12, provided with packing rings, and screwed to an intervening tubular connector 13. Each cylinder may be cast with the corresponding segment forming the periphery of the block which rotates in housings 14 and carries a ported head-plate 5 over which is the housing cover 19. Bolts 27 secure the cover 19 and the housing 14 to the piston-casing 15. A sector of the cover 19 is partitioned into adjacent passages 41, 42, air or mixture under pressure being supplied to the passage 41 and to the combustion chamber by ports 43 and 47 in the members 19, 5 respectively. Diametrally-opposed openings 47 register with openings in the head containing sparking plugs 46. The passage 43 and an opening 44 together with internal radial ribs promote cooling. The cylinder-blocks and their extensions 6 rotate in bearing sleeves 17, 36. A third bevel-wheel 68 transmits the drive to the propeller-shaft 65, the compartment 66 being used for gearing to drive the oil-pump 72. A charging pump 55 is driven by bevel gearing from the horizontal cylinder-block 14 and is surmounted by two magnetos 59 driven by bevel gearing from the other cylinder block. A fan is mounted on the outer end of extension 6 and forces air through a casing 78, Fig. 12. The air enters between the walls of the heads of the cylinder-block housings, circulating through apertured partitions therein. Ribs of varying length are formed on the cylinders.
