Title: Improvements in torches
IPC: F21S8/00
Filed: 1930-06-27
Abstract: 353,653. Electric battery lamps. BAXTER & CAUNTER, Ltd. and KETTLEWELL, G. W., 221, Tottenham Court Road, London. June 27, 1930, No. 19577. [Class 39 (ii).] A torch for displays at galas, fÛtes, carnivals and the like comprises one or more electric lamp bulbs 3 enclosed in a translucent slide 2 mounted on the end of a staff 1 and adapted to receive current from a dry battery 7 mounted on or in the staff. The shade 2 may be of white or coloured material, or the bulbs 3 may be coloured. The top and bottom plates of the shade are formed to prevent light being thrown on to the bearer ; they may be formed as reflectors to concentrate the light within the shade, or separate reflectors may be employed. The battery 7 may be secured to the staff 1 by a pair of clips 8, Fig. 1, and may rest on a metal bracket 9 forming a terminal to which one lead 6 may be connected, the second lead 5, being connected to the terminal 10 through a switch 11. Alternatively the staff may be formed from two tubular sections 1, 1x, Fig. 2, of non-conducting material connected together by the threaded engagement of a metal sleeve 12 secured to the section 1 and a metal cap 13 secured to the section 1x. The terminal 10 contacts with a part 14 to which the lead 5 is connected, the part 14 being secured to the section 1 at 15, whilst the lead 6 is connected at 16 to the cap 13. In the form shown in Fig. 3, the sections 1, 1x are made of metal and the part 14 constitutes a switch which is moved longitudinally by an external button 17 or the like. The part 14 is insulated from the section 1 by means of a sleeve 18 the inner end of which is turned inwardly to prevent endwise movement of the battery.

IPC: C08G61/12
Filed: 1971-06-09
Abstract: 1305852 Copolyketone film E I DU PONT DE NEMOURS & CO 9 June 1971 [10 June 1970] 19675/71 Heading B5N A polymeric film comprises a plurality of strata each of the same copolyketone composition wherein adjacent strata are of different morphology, one of said adjacent strata being crystalline and the other amorphous, the polyketone having the following recurring units, wherein the moiety is either (T moiety) or (I moiety) and the T:I ratio varies from 90:10 to 50:50 for the crystalline stratum and from 90:10 to 0:100 for the amorphous stratum, the T:I ratio of the amorphous stratum being no greater than that of the crystalline stratum. In one embodiment the film is made by treating one surface of an oriented or unoriented crystalline film to destroy its crystallinity e.g. by passing the film over a cooled drum while flame treating the exposed surface to render it amorphous. In another embodiment an amorphous film is extruded on to a crystalline film, the amorphous film being quenched to prevent it crystallizing and the crystalline film being cooled by a cooled drum. Alternatively an amorphous film and crystalline film may be laminated by heat and pressure e.g. in a nip formed by one cold roll and one heated roll. The film is suitable for packaging foods or metal parts having good barrier properties, being resistant to heat, solvents, acids, bases and fats and being heat sealable. The film may also be used as electrical insulation.
