Abstract: 483,391. Control of A.C. commutator motors ; electricity supply. BRITISH THOMSON-HOUSTON CO., Ltd., and BARWICK, E. C. Nov. 5, 1936, No. 30162. [Class 38 (iii)] [Also in Group XXXV] A shunt polyphase commutator motor 1 is controlled by an induction regulator 8 comprising two units each with primary and secondary windings 10, 9, the direction of rotation of the flux being opposite in the two units and the secondary windings being connected in series, and the resultant torque on the regulator is reduced by injecting into the secondary circuit a voltage which makes the phase relationship between current and voltage more nearly equal in the two units. The injected voltage may be obtained from a transformer 5 having a primary winding connected in delta, or having its windings connected zigzag. Where the injected voltage is obtained from an auxiliary stator winding of the motor, this is situated in an appropriate position to give the desired voltage phase.

Patent GB-1049892-A (GB)
Title: Catalyst composition
IPC: C10G11/05
Filed: 1963-05-08
Abstract: A catalyst composition comprises a crystalline aluminosilicate having a silica/alumina ratio in excess of 3 and uniform pores between 6 and 15A DEG  in diameter and containing cations below sodium in the electromotive series, or calcium, ammonium, hydrogen or organic nitrogen base ions, or mixtures thereof, and less than 3% by weight of alkali metal ions.  The aluminosilicate in a proportion of 1-90% by weight is suspended in and distributed throughout a matrix of a binding agent, and the composition optionally contains an additive to increase its porosity.  The aluminosilicate is prepared by replacing at least 70% of the alkali metal ions in e.g. a V-zeolite by base exchange with a solution containing the appropriate cations, particularly calcium, rare earth, magnesium, manganese, hydrogen and/or ammonium ions.  The binder may be an inorganic oxide gel, e.g. alumina, silica, zirconia, magnesia, halfnia, thoria, titania or mixtures of these, particularly co-gels containing at least 55% of silica with at least one of the others or beryllia, or it may be an activated metal powder e.g. aluminium or iron containing alloys, a clay, e.g. montmorillonite or kaolinite, charcoal, graphite, mullite, kieselguhr, activated carbon, bauxite or silicon carbide.  Mixture of aluminosilicate and binder may be accomplished by ball milling, preferably under water, or the aluminosilicate may be dispersed in finely divided form i.e. less than 40 microns in a hydrosol or hydrogel, or it may be added to one or more of the reactants used in forming the hydrosol, or it may be mixed with the reactants in e.g. a mixing nozzle.  The hydrogel formed may be broken up to desired size e.g. 1/16 " - 1/8 " by extrusion, casting or pelleting, or where microspheres of 20-300 microns are required, the hydrosol may be introduced into e.g. oil, where the hydrosol globules set to a hydrogel and pass to an underlying aqueous layer and are removed. Base exchange may take place before or after mixing with the binder, and in the former case, a further base exchange may be required subsequently to remove alkali metal ions, e.g. derived from silicates in the binder.  The porosity imparting additive, up to 40% by weight in the composition, and of particle size range 1-40 microns, may be clay, alumina, zircon, barytes, carbon, wood flour, silica, magnesia, recycle catalyst fines or spent cracking catalyst fines.  In subsequent preparative treatment, or during use, combustible additives, e.g. carbon or wood flour, may be removed.  The final composition is washed, dried at ambient temperature, or better at between 150 and 600 DEG F. for 4-48 hrs, and activated by heating e.g. in air at 500 DEG  - 1500 DEG F. for 1-48 hrs.  Selectivity is improved by exposing the composition to an atmosphere containing 5% steam at a temperature between 400-1450 DEG F. and a pressure between atmospheric and 500 psig for 2-100 hrs.

A bevel gear generating machine comprises a device 17, for sensing the position of a toolhead 4, and a servo-control system including an actuating device 49 for holding the sensing device in a predetermined position during a generating operation. The tool 8 on a cradle 9 in the head 4 is fed by a piston 15 to the generating position. The head carries a plate 27 on which a slide 29 can be moved by a motor 43 driving through worm-gearing 41, a reversing clutch 38 and a rack 30. The lower position of the slide 29 is determined by a stop 57 engaged by an abutment 56 adjusted against a scale 60 by a hand wheel 54. A clutch 10, to start the generating motion, is actuated by a dog 58 engaging a switch 59, which also switches off the motor 43. The piston 15 is controlled by the valve 17 engaged by surfaces 50 or 51 on the cam 49 adjustable against a scale 52 by a hand-wheel 46. In operation, the tool roughs out a tooth-space as it approaches the work under the control of the cam surface 50 which is moved upwardly by the motor 43. The generating position of the head 4 is determined by the cam surface 51. The valve 17 is urged against the cam surfaces by a solenoid 21 which is deenergized at the end of the generation to allow a spring 20 to retract the valve. Since the drive 41 is irreversible, the clutch 38 is momentarily released after generation to allow the slide 29 to drop down.

These groups may be substituted with halogen or other functional groups such as alkoxy or aryloxy. Preferred compounds have one of the formulae HaSiRbOR(4- ab) <FORM:1059455/C3/1> <FORM:1059455/C3/2> (SiRHO)y or R11SiH2O(SiRR1O)nSiH2R11 wherein R, R1 and R11 which may be the same or different, are C1- 4 alkyl; a,b and c=1, 2 or 3; a+b=2, 3 or 4; d is an integer up to 12; x=0 or an integer; y=0 or is an integer from 3-8; and n is an integer greater than 50.  The organic hydroxy compound may be an alcohol, phenol, carboxylic acid or oxime and included are compounds containing an enolizable CO group (see Example 11).  The catalyst may be represented by the formula R1R2NOH, wherein R1 and R2 are H or hydrocarbon.  R1 and R2 may be linked together. The reaction is best performed at - 10 DEG  C. to + 100 DEG  C.; inert diluents may be present.  Suitably stoichiometric proportions of reagents are used with 0.1-10% by weight of catalyst. Polysiloxanes of the formula <FORM:1059455/C3/3> wherein x is 140 or 339, are prepared by reaction of an a ,o -dihydroxy - dimethylpolysiloxane oil with chloromethylsilane in the presence of triethylamine, in diethyl ether.  When x=140 the starting polysiloxane has a viscosity of 505 cs. at 25 DEG  C., but when x=339, this viscosity is 5000 cs. at 25 DEG  C.
