Abstract: 458,050. Photographic fixing-compositions. KODAK, Ltd., Kingsway, London.-(Assignees of Crabtree, J. 1., and Russell, H. D.) Oct. 23, 1935, No. 29240. Convention date, Oct. 25, 1934. [Class 98 (ii)] A stable mixture of sodium or other thiosulphate crystals and solid acid is produced either by coating the crystals with a sulphurization inhibitor, such as a sulphite, or by distributing the sulphurization inhibitor through the individual particles of thiosulphate, and mixing the crystals with solid acid, such as boric or citric acid. Other thiosulphates referred to are those of the other alkali metals, of ammonium, of primary, secondary and tertiary amines, and of quaternary ammonium bases. Sulphurization inhibitors include sulphites of the above bases and sulphur dioxide dissolved in suitable solvents capable of forming solid compounds by reaction therewith. Crystallized sodium thiosulphate may be mixed with anhydrous sodium sulphite, and the mixture heated, whereupon the crystals first dissolve in the water of crystallization to give an intimate mixture and then the water is driven off to leave both the sodium thiosulphate and the sodium sulphite in an anhydrous condition. The mixture is then mixed with sodium bisulphite, boric acid, potash alum and anhydrous sodium acetate. In a modification sodium thiosulphate is moistened with a solution of sulphur dioxide in triethanolamine and alcohol, and the crystals are dried and mixed with the above additional constituents.

Abstract: 504,622. Mercury switches, DUNN, P. W., and ALBERY, D. A. R. Oct. 27, 1937, No. 29374. [Class 38 (v)] A safety switching apparatus for use on vehicles and aircraft in which as a result of shock or inversion, mercury is displaced to make or break an electric circuit, is screened by a casing and mounted so that it may be turned for operation by a handle external to the casing. In the normal position, the switch which comprises a base 11, a deflector 16, and a cover 17 as described in Specification 418,232, is supported in trunnions 23 which are formed from the contacts 12 bridged by mercury in a space 10 and rotatably mounted in brackets 24 secured within, but insulated from a metal casing 25 which forms an electrical screen. Contacts 12 are connected to terminals 30 by spring-pressed conductors 26 and cables 28. A stirrup-shaped handle 38 with a knob 50 encloses casing,25 and is secured at its ends to spindles 33 which pass through the casing 25 and carry arms 34 connected to but insulated from the trunnions 23. A spring-pressed plunger 45 (not shown in Fig. 1) connected to a terminal in a socket 142, contacts with an insulating segment 44 of a ring 43 connected to the casing. A contact 40, touching the mercury, engages contacts 41 which are connected to a terminal in a socket 42, which contacts may be replaced by a flexible connection. Fig. 4 is a diagram of external connections, wherein a battery 55 is connected to output terminals 56 through contacts 12 and the mercury, and a generator 57 changes the battery 55 through the mercury and contacts 40, 41. Upon occurrence of a shook, the mercury is jerked into a space 18 in the base 11 to break the battery and generator circuits, while when the switch is overturned by accident these circuits are broken by the mercury flowing through an opening (not shown) into a space 15. With manual operation, in addition to the flow of mercury, contacts 40 and 41 are separated, and disc 43 rotates so that its conducting part contacts with the plunger 45 to connect the casing 25 to an earthing terminal 58. When the switch is moved back for resetting, a valve 20 is opened manually or by a cam to allow the mercury to flow back into the space 10 by depressing a plunger 51 which acts through plungers 52 and 22.

Abstract: 803,433. Milling-machines. SMITH, G. R. Oct. 17, 1955 [Oct. 18, 1954], No. 29483/55. Class 83 (3). Apparatus for performing a number of machining - operations simultaneously on valvebodies 20, &c., Fig. 1, comprises powered means for moving a number of tools 18, 19 to and from work-tables 12 on a movable carrier 11, first locking-means 55, Fig. 5, for locking the tables to the carrier, and second locking-means 93, Fig. 3, for locking the carrier to the base, and means co-ordinated with the powered-means to actuate motor-means 33, 72, 84 for moving the tables and carrier. The valve-bodies are each located by pegs 115, Fig. 4, and clamped by yokes 120 to a table 12. Each table carries a gear 39, Fig. 5, which can be connected to a driving-gear 38 by a pinion 42 engaged by a cam 45 engaging a follower 44. Each table also carries a locking- pin 55 which can be moved into a resilientlymounted seating 57 in the carrier 11 by rack- and-pinion gearing 53, 50, 49, 48, operated by a rack-plunger 77 which rotates a nut 78 to raise and lower a yoke 71 engageable with the rack-rod 48. Another plunger 89, Fig. 3, operates rack-and-pinion gearing simultaneously to move the pin 93 to lock the carrier 11 to the base and to disengage the adjacent tablerotating pinion 42. In operation, motors 17 rotating the milling and threading tools 18, 19, are started, the tables 12 being locked to the carrier 11 by the pins 55, and the pin 93 locking the carrier 11 to the base being retracted. There being a partly-machined gate-valve-body opposite the cutter 18 and a fully-machined body opposite the thread-milling-tool 19, a new gate-valve-body is clamped in the loading- position, and a switch is closed to energize a solenoid causing the fluid-operated rack-plunger 30 to advance and so rotate a gear 29 fast with the gear 38. The carrier 11 thus rotates to position the new body 20 opposite the cutter 18, and to carry the finished body to the loading- station. At the loading-station, the tablerotating-gear 42 is pulled out of engagement with the gear 38 by operation of the plunger 89 and the carrier is locked by the pin 93. At the milling-station, the cutter is advanced and the planetary-head operated to machine the seat 23, Fig. 4. When the cutter is retracted; a switch is operated to cause the plunger 77 to advance, thus raising the yoke 71 to lift the table slightly on a bearing 69 and to cause the rack-rod 48 to unlock the table. At the same time, a timer is operated by a pinion 82. The gear 38 is next rotated by operation of the plunger 30 to rotate the tables at the machining-stations by 180 degrees. The timer then causes re-locking of the tables. The planetary-threading-tool 19 has meanwhile cut the threads 125. The planetary-tool-heads may be as described in Specifications 564,871 and 661,011.
