Title: Improvements relating to artificial textile yarns and fabrics made therefrom
Inventor: GIBBINS LESLIE BRISBANE
IPC: D02G3/22
Filed: 1956-01-20
Abstract: Yarn consists of continuous fine and coarse filaments, the former being from one-third to one-eighth of the denier of the latter and at least twice as numerous and having, suitably, a total denier of twice to one-half that of the coarse filaments. The filaments may be of a cellulose derivative such as cellulose acetate, triacetate, propionate or butyrate, reconstituted cellulose such as viscose and cuprammonium or as produced by saponification of cellulose acetate filaments, or they may be of synthetic materials such as polyhexamethylene adipamide, polyethylene terephthalate or polyacrylonitrile.  The fine filaments may be of "roundish" cross-section and the coarse filaments may be of elongated cross-sectional shape having a length-to-breadth ratio of at least 5 : 2 and curved into a horse-shoe or S-form or straight with bulbous ends.  The fine and coarse filaments may be extruded through separate jets and associated immediately after extrusion, or they may be extruded simultaneously, through orifices of different size and/or contour in a common spinning jet.

Title: Improvements in or relating to thermodynamic blast devices
IPC: F02K7/067
Filed: 1950-01-27
Abstract: 673,197. Jet propulsion plant. LINDEROTH, E. T. Jan. 27, 1950 [Jan. 29, 1949], No. 2248/50. Class 110(iii) [Also in Groups XII, XIII and XXIX] A jet-propulsion unit comprises five Venturi tubes 1d discharging into a common series of ejector tubes 30a leading to a propulsion nozzle, and pipes 33 interconnecting adjacent tubes 1d. The tubes 1d are formed at or near their throats with an annular sharp edge facing downstream so that they serve as aerodynamic non-return valves (see Group XXIX), permitting free flow in the normal direction but offering considerable resistance to flow in the opposite direction. Fuel is injected in to the tubes 1d at 32, whilst air is obtained from an inlet 37. The unit is started by charging all the tubes 1d with a fuel-air mixture and then igniting the charge in one tube. The combustion passes to an adjacent tube by way of one of the tubes 33, and thus in turn the charge in each tube 1d is ignited. When the first tube is again reached it will have drawn in a fresh charge, and so the cycle of operations is sustained. Each tube 33 has a flared inlet 34 at one end and a nozzle. 35 at the other end to facilitate flow in one direction only. Cooling air is drawn through jackets 8b surrounding the tubes 1d by the action of the ejectors 30a. Any reverse flow that may take place through the tubes 1d is passed to the propulsion nozzle by passages 30b.

Patent GB-1584322-A (GB)
Title: Fire prevention trough
IPC: A62C3/06
Filed: 1978-01-20
Abstract: The fireproof tub has shafts (2) which run upwards from the tub base and, on the base side, are hydraulically connected to one another. The shafts (2) only have openings at the top and bottom. The shafts (2) shaped in a honeycomb-type manner are assembled to form a grid and produced from trapezoidally profiled sheet-metal strips (3). The grid is located with its underside at a distance from the tub base in order that the liquid running into the tub can be rapidly distributed over the entire tub base and is at the same level in all shafts (2). As a result, each individual shaft (2) is cut off in a syphon-like manner from the air supply from the bottom. In the event of fire, the flame is extinguished after a short period of time because an insufficient amount of oxygen from the air passes through the narrow shafts (2) to the liquid surface. <IMAGE>

Abstract: 752,799. Automatic guns. SOC. D'EXPLOITATION DES MATERIELS HISPANO SUIZA. Jan. 26, 1954 [Jan. 30, 1953], No. 2384/54. Class 92 Relates to an automatic gun in which a breech-block 1, Fig. 2, slides in a breech-case 2 rigid with the barrel 3, the breechcase 2 and barrel 3 constituting a recoiling system slidable with respect to a fixed envelope 4 between which and the recoiling system is interposed a spring 5 or other, e.g. hydraulic, shock absorbing device. Each counterrecoil movement of the recoiling system 2, 3 produces a transverse feed of a fresh cartridge towards its waiting position and temporary locking means 15, 16 interposed between the envelope 4 and breech-case 2 are adapted to hold the breech-case 2 in a rear position to prevent temporarily the operation of the cartridge feed mechanism when, due to a lagging in the rearward movement of the breechblock 1, the cartridge feed would tend to take place before the breech-block has moved sufficiently rearwards to clear the space to be occupied by the fresh cartridge. The cartridge feed mechanism comprises a carriage 7, Fig. 4, reciprocable transversely in a guide 8 on the envelope 4, the carriage 7 carrying retractable pawls 9 which push the cartridges successively to the waiting position A. Reciprocation of the carriage 7 is effected. by a lever 10, Fig. 5, one end 11 of which engages the carriage 7 and the other end 12 carrying a roller 13 engaging in an oblique slot 14 in the front part of the breech-casing 2. The locking means comprises spring-urged pawls 15, Fig. 2, pivoted directly on the envelope 4 or, as shown, on shock absorbing means 20, 21, 22 connected to the envelope 4. The pawls 15 are adapted to engage bearing surfaces 16 in the side walls of the breech-case 2 when it moves to a rearward position, but the pawls 15 are provided with inclined surfaces 18 which are in the path of the recoil of the breech-block 1 and are disengaged from the bearing surfaces 16 by the action of the breech-block 1 on the inclined surfaces 18, thus permitting forward movement of the breech-case 2 and feeding of a fresh cartridge. The arrangement is such that disengagement of the pawls 15 from the bearing surfaces 16 will be effected only when the breech-block 1 has moved rearwardly a distance sufficient for clearing the path of the fresh cartridge. With normal synchronism of the recoil and firing cycles the pawls 15 are inoperative and only engage the bearing surfaces 16 to retard the forward movement of the breechcasing 2 when for some reason or other there is lagging in the rearward movement of the breech-block 1.
