Title: A selector for selecting a suitable adhesive for the bonding of two substrates
Inventor: VAUGHAN GEORGE
IPC: G09F11/23
Filed: 1969-05-28
Abstract: 1299595 Adhesive selector DUNLOP HOLDINGS Ltd 27 May 1970 [28 May 1969] 26835/69 Heading G5C In an adhesive selector the information for the joining of substrates is carried on two relatively rotatable discs 10, 13 each divided into segments 11, 14 and each segment having a circumferential marking identifying a substrate. In addition each segment of disc 10 has a series of radially distributed markings 12 identifying different adhesives and each segment of disc 13 has at least one window 15, located on a different radius to that of the windows on the other segments. The discs rotate one above the other about a central pivot such that when a substrate marking on one is aligned with a substrate marking on the other, the adhesive suitable for joining the substrates may be seen on disc 10 through a window in disc 13. A further disc 18, from which segment 16 has been removed, is rotatably mounted on disc 13 to facilitate the alignment of the segments.

Title: Method of making sheet metal elements with passages therein
IPC: B21C37/14
Filed: 1954-09-17
Abstract: 774,008. Making heat-exchanging sheets; stamping; rolling; welding by pressure. IMPERIAL CHEMICAL INDUSTRIES, Ltd., and MANNING, I. Oct. 17, 1955 [Sept. 17, 1954], No. 26979/54. Classes 83 (2) and 83 (4). In making metal elements with passages therein by cold pressure welding, e.g. by rolling together metal sheets with stop weld material therebetween where the passages are to be located, the material is an organic polymeric material containing no elements other than carbon, hydrogen and oxygen and which on heating to a temperature between the temperature of pressure welding and the melting temperature of the metal changes into the gaseous state without leaving a residue and the sheets are subsequently heated to gasify the material. The material may be in the form of a thin sheet or film but preferably a solution or liquid dispersion of the material is printed on one of the sheets and dried. In examples, an aqueous dispersion of polymerized ethylene which may be stabilized by an amine stearate type of emulsifying agent, a solution of methyl methacrylate polymer in benzyl alcohol or a solution of poly-iso-butylene in tetra-hydronaphthalene may be applied by the silk screen process and dried under infra-red radiation. The pressure created by the gasifying of these materials may be used to expand the passages, or the gas may be allowed to escape and the passages subsequently expanded by hydraulic pressure.

Title: Improvements in or relating to apparatus for removing secretion from the respiratorypassages
IPC: A61M1/00
Filed: 1956-09-04
Abstract: 796,724. Respiratory appliances. DRAGER, O. H. Sept. 4, 1956 [Sept. 5, 1955], No. 27055/56. Class 81 (2). An appliance for inducing an artificial cough, in order to dislodge mucous from the respiratory passages comprises an evacuated vessel which is momentarily connected to the lungs through a face mask. Under normal circumstances a chamber 5 is connected to atmosphere through a port 6 and to the face mask 8, so that the patient can breathe normally. However, when a plunger 10 is pressed upwards it causes a valve 13 to close this port and opens a valve 14, so that the mask is now connected to a source of vacuum 1. The sudden contraction of the lungs resulting from the application of vacuum, dislodges secretion and moves it to the upper resp:ratory tracts from which it can be easily removed. After the opening of the valve 14 the pressure in the lungs slowly returns to normal by air entering the system through an orifice 18.

Abstract: 478,976. Etching cellulose derivatives. GMACH, L. T. Oct. 6; 1936, No. 27089. [Class 100 (ii)] In a process for etching cellulose derivatives such as cellulose nitrate or cellulose acetate, the surface to be etched is loosened or softened, e.g. by the application thereto of acetone, amyl acetate, sodium or potassium hydrates or carbonates, or cyanide solutions, before the design is printed thereon.

[Class 98 (ii)] Relates to apparatus for copying kinematograph films in which a positive film is exposed behind a perforated negative film, both films being displaced relatively to the source of light, and in which means driven in synchronism with the displacement of the films is provided for forming perforations in the positive film ; and consists in the provision of mechanical means for engaging the perforation of the negative and positive films both to displace them and to preserve register during displacement. As shown in Fig. 2, the positive film 10 is fed, with the negative film 11, past a printing lamp 16 and the films are separated and received on take-up spools 5, 4 respectively. Between the spools is arranged a slide 32 carrying feed claws 18 19 adapted to engage perforations respectively of the negative and positive films. The slide and claws are operated by eccentrics 17, 20, 21. Perforations are formed in the positive film by a punch 24 operated by an eccentric 25 interconnected with the eccentrics 17, 20, 21. In starting, the positive film is first fed by adhesion to the negative film. When copying lenticular films, the positive film is perforated and embossed. Fig 3, shows a modification in which a punch 39 is arranged in advance of the exposure gate and the films are fed by a single claw 41 engaging perforations both in the negative and positive films 35, 36. In this apparatus the films are given successive exposures at two gates 44, 48, and to avoid fogging, the films are backed by a black film 62. The .exposure gates 44, 48 are furnished with relatively displaceable slides 58, 59, Fig. 5, for the copying of sound films. Specification 345,230 is referred to.

As shown the melt flows by gravity along a trough into which depend a plurality of agitators 5 arranged along the flow path and driven by a motor 8 through gears 3 and clutches 7. The agitators are mounted in a housing 1 which is transportable by crane and carries also a heat shield 14. Soda, lime or other treatment agent is supplied from a device 19 to form a slag 21; flow of the melt is regulated by a sluice gate 27. Agitators may be selectively driven or independently driven at different speeds and may be of different lengths; preferably they act in the slag/melt interface. Adjacent agitators are preferably contro-rotating, see Fig. 2 (not shown). Two such flow paths may be fed from a blast or melt furnace (16, Fig. 4, not shown). The furnace slag is separated and discharged at 17 before treatment, and treatment slag at 24.
