Title: Improvements in the preparation of substituted oxazolones
IPC: C07D263/42
Filed: 1944-05-31
Abstract: Substituted oxazolones having the formula <FORM:0588101/IV/1> are obtained by treating a thio-acylamino acid having the formula <FORM:0588101/IV/2> wherein R1 represents an alkyl, alkenyl, aryl or aralkyl group which may include substituents such as halogen atoms or methoxyl groups and wherein R represents hydrogen, methyl or a substituted methyl group, with a compound of a metal adapted to yield with the sulphur a water-insoluble sulphide.  In one form of the invention, the oxazolones are obtained by ring closing condensation from a metallic salt of the acid resulting in the separation of a water-insoluble sulphide.  The thioacylamino acids are obtainable by treating glycine or an a -substituted glycine R.CN(NH2).COOH in alkaline solution with a dithio acid R1CS2H, or its ethyl ester, or a thion-ester R1.CS(OMe).  In examples: (1) thiohippuric acid (obtained by the condensation of methyl thion-benzoate with glycine in the presence of sodium hydroxide) is treated with silver oxide in dry ether to obtain 2-phenyl-5-oxazolone (readily convertible into 4-benzylidene-2-phenyl-5-oxazolone and into hippuric anilide); (2) 2-(phenylthio acetyl amino-carbonylmethyl)-5 : 5-dimethyl-thiazolidine-4-carbonylic acid (prepared by treating the sodium salt of 2-C-glycyl-5 : 5-dimethyl-thiazolidine-4-carbonylic acid with methyl dithiophenylacetate in alcoholic soda solution and liberating the free acid) is treated with silver oxide in chloroform suspension to obtain the corresponding oxazolone.

Title: Improvements in or relating to controlling agricultural tractors
IPC: A01B67/00
Filed: 1948-04-19
Abstract: 650,387. Operating clutches. ZBROJOVKA BRNO, NARODNI PODNIK, April 19, 1948, No. 10804. Convention date, June 27, 1947. [Class 80(ii)] [Also in Groups XXIX and XXXI] In an agricultural tractor hauling an implement which is raised out of and lowered into its operative position by a hydraulic device any resistance to the operative movement of the implement is transmitted to the main cylinder of the hydraulic device and any increase in the resistance due for example to an obstruction causes an increase of pressure in the cylinder which sets into operation a mechanism to disengage the clutch of the tractor engine and re-engagement of the clutch is dependent upon the engagement of the reverse drive of the tractor. In the embodiment shown, when the implement meets an obstruction the pressure of liquid in the main cylinder 1 is increased as the implement is connected by a rod 4 to the piston 3 within the cylinder. The excess pressure forces a piston 6 in a cylinder 5 to the left against a spring 7 thus allowing liquid to flow through ports 8, 9 into a subsidiary cylinder 10, the port 8 being closed by the piston 6 through the action of the spring 7 on the pressure being equalized. The liquid in the cylinder 10 forces a piston 11 to the left  against the action of a spring .12 and a rod 17 connected to the piston 11 rotates a twoarmed lever 18 about its pivot 19 in an anticlockwise direction. This rotation causes disengagement of the clutch through a rod 20, a pedal 21 and rod 22. The piston 11 stays in this position with the clutch disengaged since escape of the liquid from the cylinder 10 through ports 13, 16 is prevented by the position of a piston 15. Movement of the piston 15 can either be effected directly by engaging the reverse drive on the tractor or can be preceded by engagement of the reverse drive and effected by a hand lever 28 which controls the hydraulic device for raising or lowering the implement. The piston 15 which is urged to the left by a spring 24 is connected directly by a rod 42 to a member 40 slidable on a fork 37 of the change-speed gear so that movement of the fork 37 in the direction of the arrow by the change-speed gear lever 35 moves the member 40 and the piston 15 to the right, thus opening the cylinder 10 to the exhaust port 16. The piston 15 is alternatively connected by rods 25, 41 pivoted at 25 to the member 40 so that after the reverse drive has been engaged, the fork 37 preventing any movement of the member 40 to the left, the lever 28 pivoted at 29 is moved in the direction of the arrow causing the rods 41, 25 to act as a toggle linkage and move the piston 15 to the right thus opening the ports 13, 16 to exhaust and subsequent re-engagement of the clutch. In the former construction movement of the member 40 to the right is necessary whilst with the latter construction it is only necessary for the fork 37 to prevent tne member 40 moving to the left. Specification 632,884, [Group I], is referred to.
Patent GB-481642-A (GB)
Title: A process for stabilizing organic sulphides
IPC: C07D331/02
Filed: 1937-04-15
Abstract: To stabilize, i.e. prevent the polymerization of sulphides containing the Group <FORM:0481642/IV/1> , small quantities, e.g. 1 per cent by weight of hydrogen sulphide, hydrogen selenide, hydrogen telluride, or derivatives of these substances, or products giving rise to the formation of these substances, are added to the sulphides.  The term "derivatives of these substances" does not include substances containing only sulphur, selenium or tellurium atoms forming part of a <FORM:0481642/IV/2> , <FORM:0481642/IV/3> or <FORM:0481642/IV/4> group.  Substances with strongly acid or alkaline reactions which might aid polymerization are also excluded.  Suitable stabilizing agents include metallic sulphides, alkyl sulphides, mercaptans or corresponding selenium or tellurium compounds.  Substances such as di- or tri-thiocarbonic acid alkyl esters, seleno-urea or seleno-carbanilide which yield stabilizers under the influence of light air and moisture may also be used.  In an example, to ethylene sulphide produced by distillation from a reaction mixture containing ethylene oxide and potassium thiocyanate in aqueous solution is added 0,025-0,5 per cent by weight of ethyl, phenyl or naphthyl mercaptan, or ethyl sulphide or hydrogen sulphide is introduced until 0,025-0,1 per cent has been taken up.  Such stabilized sulphides may be used alone or with other substances as vermicides.ALSO:The Specification as open to inspection under Sect. 91 relates to the use as insecticides, fungicides and bactericides of sulphides containing the group <FORM:0481642/VI/1> , whether or not mixed with other active substances, or with diluents such as hydrocarbons or kieselguhr, and whether used as such or stabilized by addition of phenols or by addition of H2S, H2Se, H2Te or derivatives of these as described in the accepted Specification.  The low molecular volatile sulphides may be used as gassing insecticides and high molecular compounds may be used as contact or stomach poisons. Examples of the active substances are ethylene-, butylene-, cyclohexene-, styrene-, butadiene- and oxypropylenesulphides. This subject-matter does not appear in the Specification as accepted. p
