The sleeve carries the bearings 22 which are housed in casing 23 bolted to the end plate 25 of the machine frame 6 ; and in the sleeve extension beyond the end of the shaft, the cables 10 are held by clips 38 in channelled sleeve or spider 39 of insulating material. The brush holders 18 are carried on a support 19 secured to the plate 25, and a terminal box 40 is mounted on a casing 36 enclosing the slip ring connections. The cables are wedged into the channels by wedges 11 secured by a retaining ring 12. In the machine shown for converting three phase supply of one frequency to a six phase supply of variable frequency, a single or double induction regulator 5 is mounted on the machine casing, and the cables are laid in groups in the channels so that the sum of the currents flowing in the cables of a group at any instant is zero. A fan 26 is mounted on the shaft and circulates air through the commutator, induction regulator and slip-ring housings and discharges it through a grid 32 at the bottom of the casmg 6.

Abstract: 1381004 Preparation of lubricating oils EXXON RESEARCH & ENG CO 10 March 1972 11324/72 Heading C5E Lubricating oils are produced from a petroleum feed by catalytic hydrogenation in two stages with the second stage being carried out under less severe conditions than the first stage. The first stage is carried out at 340-450‹ C., and 1500-5000 p.s.i.g. using a catalyst comprising Cr, Mo, W together with a Group VIII metal or an oxide or sulphide thereof. The second stage is carried out at 230-370‹ C. and 1500-5000 p.s.i.g. using a catalyst comprising a faujasite component and a metal, oxide or sulphide of Cr, Mo, W, and/or a Group VIII element. The feedstock can be vacuum distillate, catalytic cracking cycle oil, coker distillate or thermally cracked oil and can be derived from petroleum crude oil, shale oil, tar sand and coal hydrogenation products. In examples a blend of deasphalted oil and heavy vacuum gas oil is treated in a first stage using a presulphided catalyst comprising nickel and tungsten on alumina or nickel and molybdenum on silicaalumina and in a second stage using a presulphided catalyst comprising a mixture of nickel-exchanged faujasite and either silica alumina or alumina stabilized with P 2 O 5  and silica which has been impregnated with nickel and tungsten or with nickel and molybdenum. Up to 15% of the feed can be converted in the second stage and jet fuel, naphtha and heating oil are obtained.

Title: Improvements in the manufacture and production of alkali metal nitrates
IPC: C01D9/06
Filed: 1927-04-29
Abstract: 283,772. Johnson, J. Y., (I.G. Farbenindustrie Akt.-Ges.). April 29, 1927. Alkali metal nitrates are produced by causing nitrogen oxides in admixture with oxygen-containing gases to react under increased pressure with solutions of alkali metal chlorides of such a concentration that the resulting nitrate is deposited in the solid state, either at once or on cooling. Pressures up to 50 atmospheres! may be used. In an example, a solution saturated with respect to alkali metal chloride at room temperature is treated with the gas mixture at 6 atmospheres pressure at a temperature of 35‹ C. until the nitrogen oxides are oxidized and absorbed by the solution. The pressure is then released, solid alkali chloride added at 35‹ C., and the solution cooled to 15‹ C. to deposit alkali nitrate.

Title: Tension member position regulating system
IPC: G05D15/01
Filed: 1967-03-14
Abstract: 1,141,241. Automatic control of moving strip. WESTINGHOUSE ELECTRIC CORP. March 14, 1967 [March 29, 1966], No. 11919/67. Heading G3R. In a system for automatically controlling the tension of a motor-driven travelling strip, variations of tension are corrected by error signals, derived from angular movement of a member pressing against the strip, which modify the datum of a closed loop automatic speed control system for the motor and are limited to a small value until the member nears its desired position. As shown, tension is applied to a travelling paper web 10 by a roller 22 carried by a lever 24 to which a constant force is applied by a pneumatic ram 40. With switches 138, 140 closed, variations in tension from a desired value corresponding to a vertical position of lever 24 produce movements of the lever which are detected by a selsyn transmitter 114 the rectified output V 3  of which corresponds in magnitude and polarity to the magnitude and sense of tension error. This output is applied through PI regulators 104, 80 to correct the tension by varying the datum of an automatic speed control system for a motor 18 driving rollers 16 transporting tape 10. The speed control system compares the output of a tachometer generator 100 with the output of a manually operated reference potentiometer 92 so that any difference is applied through regulator 80, a limiter 91, and another PI regulator 54 to stabilize the speed by varying the datum of an automatic current control system for a D.C. generator 58 supplying motor 18. The current control system feeds back the voltage across a series resistor 74 through a magnetic amplifier 90 to the input of regulator 54 which controls the generator field excitation through semi-conductor controlled rectifiers 64. If the tension error lies between predetermined limits in either sense, relays 156, 172 apply such bias to a limiter 144 that limiting of the control signal is small but, if the tension error is greater, it is effective through an amplifier 190 or 194 to cause the relays to operate so that there is considerable limiting of the control signal. This permits starting up under speed control only with switches 138, 140 open and then closing them without undue shock, regardless of the position of lever 24, since tension correction will proceed slowly until tension lies between the predetermined limits.
