Patent GB-402144-A (GB)
Title: Improvements in the manufacture of artificial filaments, threads, yarns and the likeof high tensile strength and of fabrics and other materials containing the same
IPC: D06M11/38
Filed: 1932-02-19
Abstract: Filaments, threads, yarns, or the like, or fabrics containing them, of organic esters of cellulose of high viscosity, are subjected to saponification by applying the saponifying agents to the travelling materials, and immediately drying under the influence of heat to effect quick saponification.  The products have a relatively high tenacity and an affinity for cotton colours.  In the case of cellulose acetate, the viscosity as measured by the rate of flow of a 6 per cent. acetone solution against a standard of glycerine at 25 DEG  C. as 100, exceeds 30, and preferably is of the order of 50 or 200 or more.  The high viscosity ester may be obtained, for example, according to the process of Specification 207,562, [Class 2 (ii), Cellulose &c.]. The saponifiying agent comprises caustic soda or caustic potash, or sodium silicate, trisodium phosphate, sodium acetate, or ammonia, in a medium which may contain a mono-, di-, or poly-hydric alcohol, e.g. methyl or ethyl alcohol, glycols, or glycerine.  The saponifying agent may be applied to the materials by a bath treatment or by padding, the drying being effected by passing the materials over heated rollers as is described in Specifications 316,521 and 318,468, [both in Class 2 (ii), Cellulose &c.].  The extent of saponification varies from 5 to 20 or 50 per cent, up to substantially complete elimination of the ester groups.  If desired, the materials may be subjected to treatment with shrinking agents to improve their extension, as is described in Specifications 380,504, 380,505, and 389,823.  In an example, a warp of yarns made from cellulose acetate having a viscosity of 73 is impregnated with a 10 per cent. aqueous solution of caustic soda, so as to retain its own weight of liquid, and passed to a series of steam heated rollers as in the process of Specification 316,521 or 318,468.  Specifications 340,324, 340,325, 340,326, 340,436, 340,437, 343,062, and 378,858 also are referred to.  The second Provisional Specification refers also to Specifications 370,430, 371,461, and 400,996.

Title: Improvements in devices for preventing damage due to backfires in internal combustion engines and means associated therewith for preventing the theft of motor cars
IPC: F02M1/00
Filed: 1930-10-27
Abstract: 363,461. Preventing unauthorized use of engines for road vehicles, and damage from backfiring. DORES, G., 44, Rue du ChÔteau-des-Rentiers, Paris, and GIRARD, L., 86, Rue Perrier, Montrouge, Seine, both in France. Oct. 27, 1930, No. 32221. Convention date, Oct. 28, 1929. [Class 7 (ii).] A tubular member, having an open mouth directed away from and opening into an enlarged part of the mixing chamber of a carburetter conducts ignited gases, resulting from a backfire, to the atmosphere, through an escape valve. As shown in Fig. 2, the ignited gases escape through a member 150 to the atmosphere past a valve 155. A valve 55 may be provided which in the event of a backfire isolates the engine from the carburetter. A gauze screen 80 is provided in the member 150. According to the construction shown in Fig. 3, a perforated poppet valve 61 directs the ignited gases into the tubular member 150, and in the construction shown in Fig: 7, two flap valves 4, 5 isolate the carburetter from the engine in the event of a backfire. The wings of the flap valves may be locked in their closed positions to constitute an antitheft arrangement. A detent 7 engaging abutments 8, 9 is provided on the valves. The spindle 3 may be displaced laterally so that the detent at 7a, Fig. 6, is disengaged from the abutments 8, 9 and permits the valves to move freely. The spindle 3 has a conical end 12 which engages the stems 13, 14 of valves 15, 16 so that when the valves 4, 5 are locked, the valves 15, 16 are opened and thus air alone is drawn into the engine if an attempt is made to start it. The spindle 3 is held against rotation by a spring-pressed pin 33 and it is moved laterally by a key (not shown), or, as shown in Fig. 6, by a Bowden cable 37. The spindle is secured to the cable to which motion is imparted by a key 37a. Should the cable fracture the spindle 3 is displaced by a spring 36 and locks the valves 4, 5 in the closed position. The Specification as open to inspection under Sect. 91 (3) (a) describes an arrangement by which if the distant operating device is torn away claws cut the cable thus ensuring the automatic locking of the valves 4, 5. The breaking of the cable may close an electric circuit and operate sonorous, luminous, or smoke signals. Also the valves 15, 16, Fig. 6, may be replaced by a single valve coaxial with the spindle 3. This subject-matter does not appear in the Specification as accepted.
