Abstract: 323,700. Sokal, S., (Lidkopings Mekaniska Verkstads Aktiebolag). April 23, 1929. Centreless grinding.-In a centreless grinding machine the regulating wheel is driven by the workpiece by friction. A grinding wheel 1 is driven from an electromotor 3 and is mounted on a carriage with rough and fine adjustment devices 9, 10. The regulating wheel 17, carried in a swinging frame 19 adjustable on a carriage 20, is rotated by friction from the workpiece and is mounted on a shaft 18 geared to a centrifugal brake 35 which retards rhe wheel when a predetermined speed is reached. A fluid pressure or electrically operated brake may be fitted. For dealing with conical workpieces the regulating wheel is driven through a clutch before the workpiece is inserted and when the desired speed of rotation is reached the clutch is operated to cut out the positive drive. The regulatiug wheel carriages is adjustable by a screw 25. Rests.-The work-support 49 is adjusted by a screw and is locked by a wedge device 56.

One mole of lime may additionally be added to the starting material for each mole of silica present. Alumina may be recovered from the final solution by addition of ammonia to form an alumina precipitate and ammonium nitrate when the leaching step is performed in nitric acid.

Title: Improvements in and relating to cathodic sputtering
IPC: C23C14/34
Filed: 1946-04-26
Abstract: 611,282. Depositing substances by discharges. GENERAL ELECTRIC CO., Ltd., PEARSON, A., and ROLLIN, L. April 26, 1946, No. 12645. [Class 39 (i)] Apparatus for cathodic sputtering consists of a hollow glass cylinder 6 closed at one end by the anode plate 1 and at the other by the cathode plate 7. The anode plate has a connection 12 to a vacuum pump, and the cathode plate has copper cooling fins 11 attached to its upper surface. The cathode material, which may be gold foil, is clamped to the lower surface 9 of the cathode plate by means of a brass clamping ring 10. A thin hollow metal cylinder 13 is fixed to the wall to shield part of the wall of the cylinder 6 from the sputtering path; this prevents a continuous leakage path being formed between anode and cathode. A switch may be provided in the circuit for automatically interrupting the voltage supply between anode and cathode when the pressure inside the chamber rises above a certain value.

Title: Improvements in or relating to interlocked electric control circuits
IPC: B30B15/14
Filed: 1955-05-03
Abstract: 803,380. Switching systems. IGRANIC ELECTRIC CO., Ltd. May 3, 1955 [May 13, 1954], No. 12785/55. Class 38 (4). A switching system, for controlling the energization of a solenoid 18 operating an air valve V for a clutch 16 through which a press 14 is driven by a motor 12, comprises saturable reactors 20, 22, an initiating switch 24 and limit switches 28, 30 operated by the press. Reactor 22 has A.C. windings 46, 48, bias winding 52 and control winding 50, whilst reactor 20 has A.C. windings 36, 38 in series with the solenoid, bias winding 44 and control windings 40, 42. Assuming limit switch 30 and the auxiliary contacts 34 of the motor line switch 10 both to be closed and the initiating switch 24 to be in the normal position shown, the rectifier system 57- 60 (which supplies the bias windings 52, 44) also energizes control winding 50, thereby saturating reactor 22. Reactor 20 is, however, in an unsaturated state and the solenoid unenergized. Upon operation of the initiating switch, winding 50 is disconnected from the rectifiers 57-60 but remains energized by a rectifier system 62, 64, 66, 68 in the A.C. circuit of reactor 22, which system is now connected to control winding 42 of reactor 20. This reactor is, thereby, saturated and the solenoid operated in consequence. After a certain movement of the press, limit switch 28 closes and connects control winding 40 across a rectifier 70 in the A.C. circuit of reactor 20, so that saturation is maintained until the limit switch again opens-irrespective of opening of the initiating switch. The solenoid deenergizes with opening of limit switch 28.

Convention date, Jan. 28, 1930. [Classes 72 and 82 (i).] In making wrought iron by pouring ferrous metal from a ladle 32 into a slag bath 60 as described in Specification 315,827, [Class 72, Iron &c.], the relative positions of the ladle and bath are changed in two planes. The ladle is mounted on a table 31 oscillating round its vertical axis and carried by a platform 30 reciprocating on rails 34 so that the metal falls into the bath 60 along a sinuous path ; and as the ladle is tilted about its horizontal axis, each successive path is displaced from the position of the previous path and no substantial overlapping occurs. These motions are effected by electric motors 37, 44, and 48 reversed periodically to give oscillating motions by automatic switches. The rails 34 rest on a platform scale 35 so that the weight of metal in the ladle is indicated on dial 36. The slag baths 60 are carried by a train of ladles 24 running on a closed track. First the ladles 24 receive slag from a furnace, then pass under one of a battery of pouring ladles 32, then they pass to a press in which the ingot of wrought iron is pressed and slag removed, whereupon they return to the slag furnace. The ferrous metal from Bessemer converters &c. is brought in ladles 61 on carriages 62 and poured into the ladles 32 by means of crane 63.

Abstract: The invention comprises O-aryl phosphoroamidohydrazidothioates having the formula <FORM:0833156/IV (b)/1> in which X is aryl, as defined below, R1 and R4 are hydrogen or C1-C4 alkyl, R2 is C1-C4 alkyl or cyclohexyl, and R3 is hydrogen, C1-C4 alkyl, or phenyl.  The term aryl is defined as a phenyl radical or a substituted phenyl radical containing one or more substituents including chlorine, bromine, C1-C4 alkyl, cyclohexyl, phenyl, benzyl, C1-C4 alkoxy group or nitro group.  They may be obtained by reacting hydrazine, or an appropriately substituted hydrazine, e.g. phenylhydrazine or a C1-C4 alkylhydrazine with a phosphoroamidochloridothioate of the formula <FORM:0833156/IV (b)/2> in the presence of an inert organic solvent, e.g. benzene, toluene or methyl chloride.  Suitable reaction temperatures are from 0 DEG  to 50 DEG  C.  Upon completion of the reaction the reaction mixture is washed with water and any reaction solvent removed by evaporation or partial distillation under reduced pressure to obtain the desired product as a residue.  Examples are given for the production O-(2,4,5-trichlorophenyl) N-methyl phosphoroamidohydrazidothioate, O-(2,4,5-trichlorophenyl) -N-methyl-2-phenylphosphoramidohydrazidothioate, O-(2,4, 5-trichlorophenyl - N,2,2 - trimethylphosphoroamidohydrazidothioate, and O - (4 - chloro - 2 - cyclohexylphenyl) - N - cyclohexylphosphoroamidohydrazidothioate.  The products have good pesticidal properties (see Group VI).  The O-aryl phosphoroamidochloridothioates used as starting materials may be obtained by reacting two molecular proportions of an appropriately substituted amine, e.g. a C1-C4 alkylamine or cyclohexylamine with one molecular proportion of an O-aryl phosphorodichloridothioate at from -10 DEG  to 50 DEG  C., the reaction being carried out by adding a benzene solution of the amine portionwise to the phosphorodichloridothioate dissolved in benzene.ALSO:O-Aryl phosphoroamidohydrazidothioates of the general formula <FORM:0833156/VI/1> in which X is aryl as defined below, R1 and R4 are hydrogen or C1-C4 alkyl, R2 is C1-C4 alkyl or cyclohexyl and R3 is hydrogen, C1-C4 alkyl or phenyl (see Group IV (b)), the term aryl being defined as a phenyl radical or a substituted phenyl radical containing one or more substituents including chlorine, bromine, C1-C4 alkyl, cyclohexyl, phenyl, benzyl, C1-C4 alkoxy group or nitro group, are effective as fungicides and parasilicides.  They may be dispersed on a finely divided carrier and employed as dusts or they may be used in oils or as constituents in water emulsions or water dispersions.  A suitable insecticidal composition comprises an aqueous composition containing two pounds of O - (2,4,5 - trichlorophenyl) - N - methyl - 2 - phenylphosphoroamidohydrazidothioate per 100 gallons of water.
