Title: Improvements in and relating to safety locks
IPC: E05B35/08
Filed: 1937-11-29
Abstract: 490,187. Multiple-Key locks. SUSSER, H., and SUSSER, H. Nov. 29, 1937, No. 32884. [Class 44] In a change-key lock having two part-tumblers 2, 3, meshing together by means of teeth, the first set of tumblers 2 co-operating with a projection 8 on the bolt 9 is pivoted on a pin 7 carried by a pivoted arm 13 located between the bottom of the casing and a cover plate and is normally held in engagement with the second set 3 by a spring 21, but when the arm 13 is rocked by passing a pointed pin through a hole 15 in the arm and through holes in the casing and cover plate, not quite in register with the hole in the arm, the first set of tumblers is locked in engagement with the projection on the bolt. The key, Fig. 4, has an adjustable bit consisting of notched bars 23 held in place in the slotted end of the stem by a rib 26 and screw 24. When it is desired to re-arrange the key bit, the door is opened and the tumblers moved out of mesh by rocking the arm 13. After alteration of the key it is replaced in the lock, thus automatically setting the tumblers to suit the new bit, and the tumblers are brought into mesh again. In a modification, Fig. 8, a tumbler 3<1>, formed without teeth, must be displaced by the key so that a hole 30 registers with the hole 17 in the casing before the pin can be inserted; or a second key may be used to rock the arm 13, in which case, when the main key is withdrawn for alteration, the slot 31 engages the flattened end of the second key and prevents it being turned to bring the tumblers into mesh until the main key is replaced in the lock. A pin 34 on the bolt tail coacts with a slot 33 in the tumbler 3<1> to positively hold the bolt in its extreme positions. A key having a single bit may be used in which case bars differing in length are assembled in the stem.

Filed: 1967-07-20
Abstract: 1,174,128. Treating cellulosic materials. TRIATEX INTERNATIONAL AG. FOR TEXTILE RESEARCH & DEVELOPMENT. 20 July, 1967 [24 Aug., 1966], No. 33365/67. Headings D1L and D1P. In a process for improving or finishing a cellulose-containing textile, e.g. cotton fabric, by a chemical reaction employing a gaseous acid catalyst, the gaseous acid catalyst converted into the gas phase by evaporation from a liquid azeotropic mixture of an acid and water is allowed to act for a short contact time of less than 30 seconds on the textile material which is at a lower temperature than the gaseous azeotropic mixture and the concentration of the acid catalyst on the textile material is adjusted by controlling the rate of supply of heat energy to the liquid azeotropic mixture. The process may be effected below the boiling point of the azeotropic mixture or with boiling azeotropic mixtures. The azeotropic mixture may be an aqueous hydrochloric acid mixture containing about 22% by weight of hydrochloric acid, or a mixture of formic acid and water containing about 70% by weight of formic acid. In the figure fabric (a) which may have been impregnated with an aqueous mixture containing dimethylol dihydroxyethylene urea, polyethylene emulsion and a nonionic wetting agent and dried on a stretching frame to a residual moisture content of 5%, is run between guide rollers (b) over slit (c). The azeotropic mixture of hydrochloric acid and water (d) is supplied to acid resistant container (f) supplied with the required energy through heating element (g) via the controller (h), through level controlled feed pipe (e). The azeotropic mixture (d) is maintained at its boiling point (120.4C at normal pressure). Shield 1 prevents spray reaching the fabric and heated extraction hood (i) of which the inside wall is maintained at a controlled surface temperature of 130C, and extractor device (K) draw off the acid gases present above the fabric. The acid catalyst may be removed from the treated material e.g. by neutralising agents or intensive aerating extractions directly after passage through the apparatus for causing contact with the gaseous acid catalyst or after the interposition of a delay time. The process may 'be employed for the fixing of deformations in fabrics, e.g. calendar effects and stamped patterns, and for fixing pleats and seams and producing crease resistance in articles of clothing e.g. transersand shirts.
