Title: Substituted thioureas and their use as pesticidal agents
Inventor: HOLDSWORTH ERNEST CLIFFORD
IPC: C07C335/16
Filed: 1958-04-14
Abstract: The invention comprises a process of preparing substituted thioureas of the general formula ArNHCSNRR1, wherein Ar represents an aryl radical, R represents an alkyl or cycloaliphatic radical and R1 represents hydrogen or an alkyl or cycloaliphatic radical, by reacting an alkyl, dialkyl or cycloaliphatic dithiocarbamic acid with a primary aryl amine.  The substituted dithiocarbamic acid in the form of its sodium salt may be reacted with the sulphate of the aryl amine.  A mixture of carbon disulphide and an alkyl, dialkyl or cycloaliphatic amine may be used in place of the substituted dithiocarbamic acid.  In Example 3, a benzole forerunnings fraction containing CS2 is added to a mixture of dimethylamine, methanol and a coal-tar toluidine fraction of boiling-range 197-203 DEG  C.; and the temperature is maintained at 75 DEG  C. for 4 hours.  The mixture is then cooled, and the solid product-N tolyl N1N1 dimethyl thiourea -is filtered off and washed with benzene. Example 4 relates to the preparation of N-phenyl N1N1 dimethyl thiourea.  In Example 5, cyclohexylamine is reacted with CS2 in the presence of aqueous sodium hydroxide to form the sodium salt of cyclohexyl dithiocarbamic acid; and the latter is then reacted with toluidine sulphate to obtain N-tolyl N1 cyclohexyl thiourea.  These substituted thioureas possess pesticidal properties (see Group VI).ALSO:Herbicidal and fungicidal compositions comprise as active ingredient one of the following substituted thioureas, viz. N-tolyl-N1,N1-dimethyl thiourea, N - phenyl - N1,N1 - dimethyl thiourea, and N-tolyl-N1-cyclohexyl thiourea.  Details are given of phytotoxicity trials using each of the three compounds in the form of a 1% aqueous methanol suspension.

Abstract: 552,020. Delivering moulded products from moulding presses. ERICSSON TELEPHONES, Ltd., and WARD, S. H. D. Sept. 17, 1941, No. 11879. [Class 87 (ii)] A horizontal runway 7 extends between the moulding press A and a station B equipped with means for separating the several parts of a mould, the runway being on the same level as that occupied by a mould in the press when pressure has been released, so that one mould can be removed from the press and another placed therein without lifting either. The invention is described in connection with the production of the telephone switchboard plugs described in Specification 456,159, for which purpose two-part moulds 19, 22 are used, having filling apertures into which moulding material is charged. Plungers 29 extending from a pressure block 18 enter the filling apertures and, during the pressing operation, force the moulding material into the mould. On retraction of the lower platen 2 to the position shown, the mould-pressure block assembly may be grasped by a handle 30, and slid along the runway to the ejecting station at which a part of the runway is cut away so that ejecting pins 17, 21, raised by a hand-operated lever 9 pivoted at 10 or by a foot-lever 25 or by hydraulic means, successively raise the block 18, then raise the upper mould part 19 and finally, by means of pins 21, eject the moulded plugs. During separation of the block 18 from the mould, both mould parts are held by pivoted arms 20, 26 engaging grooves in the said parts. After separation of the block 18 the levers 20 are disengaged from the grooves so that the mould part 19 may be separated from the mould part 22. The ejecting station has two stops, one (8, 8) fixed and the other (32, 32) secured to a hinged framework 31 so that different kinds of moulds may be accommodated.

Abstract: 1410580 Gyroscopic apparatus SPERRY RAND CORP 19 March 1974 [6 April 1973] 12066/74 Heading G1C Gyroscopic apparatus, particularly a gyroscopic angular rate sensor for detecting and measuring angular rates of vehicular movement with respect to one or two axes and for measuring linear accelerations along the rotor spin axis, comprises a rotor 23, situated in a fluid tight cavity 22 so as to be hydrodynamically suspended therein when rotated, which is physically isolated from a stator 15 so that contaminants produced thereby cannot enter the cavity 22. Pole piece extensions 20 magnetically couple the rotor and stator so as to provide a flux path. The rotor 23 has the same external shape as the internal shape of the cavity but, is slightly smaller, the cavity 22 being formed by a cylindrical metallic ring 21 and a pair of opposed thrust bearing pads 25. Two pairs of orthoginally disposed plates 35 each coact with a hysteresis ring 24 of the rotor 23 for sensing angular displacement thereof in response to sensor turning rates about the X and Y axes, associated electronic circuitry being mounted on boards 40, 40'. The circuitry required for providing these rates together with acceleration along the spin (i.e. Z) axis comprises full wave rectifying bridges and is described with reference to Fig. 4 (not shown). The inner surface of ring 21 is provided with herringbone grooves which increase the dynamic stability of the rotor 23. One pad 25 may be provided with torquer pole pieces 30 and torquer coils 33 so that a controllable torque may be applied to the rotor 23 for example for self test purposes. The bearing surfaces 26 may be of ceramic material to reduce the possibility of rotor damage.

Abstract: 881,229. Rolling; copy-turning; altering physical structure. BENDIX CORPORATION. April 5, 1960, No. 12077/60. Classes 83 (3) and 83 (4). In a roll-burnishing apparatus, e.g. for burnishing an aircraft wheel a feed carriage or turn-table 52 having an indexable fixture 32 thereon is adapted to be clamped in a selected position and carries a flexibly supported rollburnishing tool 36, the burnishing tool 36 being biased against the work with substantially constant force by a fluid-operated cylinder 110. The periphery of a forged cast or stamped aluminium, titanium, steel or magnesium aircraft wheel 18 is first profiled by a cutter 34 also mounted on the fixture 32 and indexable into a working position by release of a handle 37 which permits the spring-loaded body 35 of the fixture to rise clear of locating recesses in a compound rest 42. The burnishing wheel 36 is resiliently mounted on the fixture 32 by flexible struts 72, 76 which are respectively attached at one end to extensions of the body 35 of the fixture and at the other end to the floating tool carrier 86. The work is rotatably supported between the plates 16, 24 of a headstock 12 and a tailstock 20, the tool 36 being biased towards the work by the substantially frictionless action of a cylinder 110 of a fluid motor. A rod 122 connects the diaphragm 114 of the cylinder with the tool support 86 and movement of the latter is limited by stops 102, 104. The turn-table 52 is transversely slidable in guides 56 and a carriage 30 carrying the whole assembly is slidable longitudinally so that in operation the wheel rim is first profiled by the cutter 34, the fixture being traversed and controlled by a tracer arm mechanism 44 acting in response to a templet 48. After profiling the fixture is indexed and the traverse repeated to uniformly burnish the surfaces of the aircraft wheel. It is said that such burnishing improves the fatigue life of the wheel.

Title: Improvements in fabrics adapted for production on twist lace machines and in the method of producing such fabrics
IPC: D04C5/02
Filed: 1925-05-12
Abstract: 261,053. Pepper, S. May 12, 1925. Lace. - Relates to the production of double faced fabrics on curtain lace machines by the use of guide bars in combination with jacks or pickers, no additional elements for mechanically acting on the warp and spool threads being used. One or both faces may carry relief, incorporating plaited pillars, wickerwork fining &c. Fig. 1 shows a machine fitted with five guide bars of which the front bar 5 is threaded with spool threads a<2> and warp threads b<2> arranged in alternation while the back bar 1 is threaded with spool and warp threads a', b'. The arrangement is such that the threads a<2>, b<2> come opposite threads a<1>, b<1> respectively. The other bars may carry spool threads c, d, e, the threads c, d being reverse twisted. These bars may be varied in number or be dispensed with. The bars are shogged every quarter motion while the pickers enter every half motion. By moving the pickers in various sequences to the positions g, h, k, r various effects such as cross-net, combination work and filet can be obtained. Scalloped edges are obtained by suppressing, at intervals, a bobbin thread f<3> which normally would form part of a plaited pillar. The warp thread b<1> thus forms a draw thread. Specification 155,925 is referred to.
