Title: Improvements relating to draught excluders for fitting to doors
IPC: E06B7/20
Filed: 1958-01-02
Abstract: 844,976. Draught excluders. BOWMAN, S. G. M., and BOWMAN, P. E. Dec. 31, 1958 [Jan. 2, 1958], No. 130/58. Class 20(3) A draught excluder for fitting to the bottom of a hinged door 1 comprises a strip 3 of plastic material, &c. provided with cam slots 8, 14 as shown in recessed parts 7, 13 of the strip. It is secured to the door by screws 17, 18 passing through the slots flanged spacer pieces 19, 20 being engaged over the screws. The slots, screws &c. are concealed by a cover strip 6 fitted beneath an overhanging lip 4. A hook 21 projects from one end of the strip to cooperate with a roller 24 fixed to the joint 2. When the door is closed the strip is in its lowest position, Fig. 1, so that the strip 26 of sponge rubber, foamed plastic &c. attached to its bottom edge is in contact with the floor. As the door is opened, the hook 21 is restrained by the roller 24 causing a lateral movement of the strip, while the inclination of the cam slots causes it to tilt to the position shown in Fig. 3. Further opening of the door causes the left side of the strip to drop until the spacer piece 19 engages the top of the slot portion 11, and consequent upward movement of the right side disengages the hook from the roller. On closing the door, coaction between the roller 24 and an inclined surface 25 on the end of the strip 3 tilts the strip back to the position shown in Fig. 3, whereupon the strip drops until it regains the Fig. 1 position. The cam slots have enlarged ends 12a, 16a permitting the passage of the spacer pieces in removing the strip from the door. The Provisional Specification describes also a draught-excluding strip which may be made of wood or metal having differently shaped slots and a hook formed integrally with the strip. The slots have branches extending to the bottom edge of the strip to permit removal of the strip from the door.

Abstract: 1,084,081. Photo-resist images. NATIONAL CASH REGISTER CO. Jan. 5, 1965 [Jan. 16, 1964], No.463/65. Heading G2C. [Also in Division C4] Relief images are produced in a substrate, which may be on a base, by coating the substrate with an amorphous layer of one or more photochromic spiropyrans in their less polar forms, imagewise exposing the substrate to u.v. radiation so that the exposed areas are changed to the more polar coloured form, treating the spiropyran with a solvent which dissolves the unexposed but not the exposed material, and removing the thus uncovered substrate with a solvent which does not attack the exposed photo-chromic material. In a modification of the process HC1 complexes of the photo-chromic material are formed and selectively dissolved. Superimposed images may be formed by coating the first relief image with further photo-chromic material and treating as above. In a further modification the material may be uniformly exposed using u.v. radiation, followed by imagewise exposure and visible light. Mixtures of photo-chromic materials may be used to prevent the formation of crystals during the preparation of the photo-chromic layer. The base may be glass or silicon and the substrate copper, aluminium, glass, tin dioxide, cadmium sulphide or silicon dioxide.

Abstract: 1,073,811. Melt spinning organic polymeric materials. CHEMIEFASERWERK " FRIEDRICH ENGELS " VEB. Jan. 7, 1965, No. 746/65. Heading B5B. In the production of filaments by melt spinning synthetic organic thermoplastic polymers, particularly polyamides, in a continuous manner, the polymer is formed by continuous melt extrusion into a continuous shaped body, preferably a film in the form of a continuous web, having a relatively high surface area/ volume ratio, and monomers and oligomers present in the shaped body are substantially completely removed from the body (after the latter have been cooled and solidified) by extracting in a continuous manner the body with a solvent for the monomers and oligomers which is not a solvent for the polymer, before continuously passing the solvent extracted body to a melt spinning zone in which it is melted and formed into filaments by a continuous meltspinning process. The shaped body, if in the form of a film web, may be caused to travel in a continuous manner in a sinuous path as a festoon through one or more solvent extraction zones and then, also in a sinuous path, as a festoon through one or more drying zones in which the web of film is exposed to a countercurrent stream of an inert gas such as nitrogen, or to a vacuum before being continuously passed to a melt-spinning zone. The passage of the film from the drying zone to the meltspinning zone may be effected in an atmosphere of an inert gas, such as nitrogen.
