Abstract: The invention comprises as a new compound bis(ethylxanthoylthioxy) - methyl phosphine oxide having the formula  <FORM:0736579/IV (b)/1> It may be obtained by reacting an alkali metal ethylxanthate with methanephosphoric dichloride of the formula CH3.P(O)Cl2 in an inert organic solvent such as benzene.  It is preferred to use at least two molecular proportions of the xanthate with each molecular proportion of the methanephosphonic dichloride.  In an example methane phosphoric dichloride dissolved in benzene is added portionwise with stirring to sodium ethyl xanthate dispersed in benzene and the mixture heated at 50 DEG  C. to complete the reaction.  The mixture is then filtered and the filtrate distilled under reduced pressure to yield as a residue the bis(ethylxanthoylthioxy)-methyl phosphine oxide.  The product is stated to be effective as a parasiticide (see Group III).ALSO:Bis - (ethylxanthoylthioxy) - methyl - phosphine oxide having the formula: <FORM:0736579/VI/1> (see Group IV (b)) is stated to be effective as a parasiticide.

Title: Improvements in austenitic non-corrodible steels
IPC: C22C38/40
Filed: 1929-11-02
Abstract: Austenitic noncorrodible steels containing 10-25 per cent of chromium, 5-12 per cent or more of nickel and generally low in carbon, have silicon added thereto and are heated to about 900 DEG C. and cooled quickly in air or water to globularize the carbides present.  A silicon content of 0,50-6 per cent is given by way of example.  The steels may also contain a small quantity of other metals such as tungsten, molybdenum, copper, titanium, vanadium. The heat treatment is said to improve the resistance to intergranular corrosive attack particularly after the steels have been heated to 500-900 DEG  C. or after they have been welded.

Abstract: 793,977. Coin-freed apparatus. ASSOCIATED AUTOMATION, Ltd. Nov. 12, 1956 [Nov. 22, 1955], No. 33396/55. Class 27 A removable cash receptacle 1 fitted in a compartment 2 of a telephone or other coin collector as used, for example, in public call boxes comprises a coin orifice 4 having a pivoted shutter 9 which is automatically opened as the receptacle is placed in the compartment and automatically closed as it is removed, a lid 6 releasable by the latch 8A of a lock 8, and a Geneva movement having its slotted part 12 connected with the shutter and its pin 12A carried on a member 11 operable by a pin or rack 13, the latch 8A being so associated with mechanism for locking the shutter closed that, when the lid is released, the latter mechanism is conditioned for reopening the shutter on replacement of the receptacle in the compartment. When the receptacle is inserted in the compartment the shutter 9 is rotated to the open position by a fixed rack 13 engaging quadrant teeth of the member 11. As the receptacle is removed for emptying purposes, the member 11 swings to close the shutter and a cam-plate 17 integral with the shutter rotates between the arms 18A, 18B of a pivoted spring-loaded Y-member 18 so that a detent 18C engages with a notch 17B in the cam-plate and thereby locks the shutter in the closed position. To empty the box 1, the lid 6 is removed by actuating the latch 8A and an extension 8B on the latch thereby abuts a projection 18E on the member 18 to disengage the detent 18C from the notch 17B; when the receptacle is again inserted in the collector, the shutter is therefore free to be moved to the open position by the member 11. and a cam surface 17A on the cam plate 17 acts upon the arm 18A to position the detent for subsequent re-engagement with the notch. The Provisional Specification describes also the rack 13 as being spring mounted or loosely mounted so that it may be used with different-sized receptacles. Specification 612,710 is referred to.
