Title: Improvements in logs
IPC: G01P5/06
Filed: 1949-01-27
Abstract: 691,525. Controllers. ABBEY, A. (Svenska Ackumulator Aktiebolaget Jungner). Jan. 27, 1949 No. 2304/49. [A Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 11, 1949.] Class 38 (iii) [Also in Group XIX] The speed of an electric motor 18 is maintained at a desired value by a clockwork or other source of constant speed 33 controlling means for varying the resistance in the motor feeding circuit, said means comprising a contact arm 38 co-operating with and movable relatively to one or more rotatable resistors 24, 25, 26, the clockwork or other source of constant speed being arranged so that the difference of speed between the electric motor 18 and the clockwork 33 determines the value of the one or more resistors that is or are inserted in the motor feeding circuit. The resistors may, as shown, be mounted on a shaft driven by the electric motor and the contact arm 38 may be mounted on a shaft driven by the source 33 of constant speed. Alternatively, the resistor may be on a shaft driven by the source of constant speed and the contact arm 38 may be mounted on a shaft driven by the electric motor. The operation of the apparatus is as follows. Initially, a strained spring 30 causes the contact arm 38 to engage a stop 28<SP>1</SP> on a contact disc 28. When the motor 18 is energised, it initially rotates at a speed greater than is required. By turning the wheels 22 and 23, the motor 18 causes the contact arm 38 to leave the stop 28<SP>1</SP> as well as a further straining of the spring 30 in a manner freeing the clockwork 33. The clockwork source of constant speed 33 then rotates the shaft 32 at a speed which is less than the speed of the wheel 22 at that instant. As a result the spring 30 is further strained and an additional displacement is o .tained between the contact arm 38 and the disc 28. The contact arm 38 now begins to engage the next contact 26<SP>1</SP> on the disc 28 whereby a resistance 26 is inserted in the motor circuit to cause it to reduce speed. Should the speed still be too high, the contact arm 38 will move to engage the next contact 25<SP>1</SP> and so on until the speed of the motor 18 is reduced to the required amount. The apparatus then serves to automatically maintain the motor 18 at this speed.

Patent GB-781706-A (GB)
Title: Hydrocracking and hydrodesulfurizing crude petroleum oils containing sulfur
IPC: C10G65/12
Filed: 1955-01-31
Abstract: Sulphurous residual oils obtained in the distillation of crude petroleum are converted into gas oil and other products by subjecting the oil to catalytic hydrocracking by contacting it with hydrogen at a temperature between 775 DEG  and 880 DEG  C. and a pressure between 200 and 2000 p.s.i.g.  After a throughput of 1 to 24 volumes of oil per volume of catalyst, the feed is discontinued, and the catalyst is regenerated by combustion of the coke deposited thereon.  This hydrocracking process may be associated with a process for cat.-cracking of gas oil; a <FORM:0781706/III/1> heavy fraction separated from the cracked products being mixed with the oil to be hydrocracked.  The preferred catalyst is a mixture of nickel oxide and tungsten oxide deposited on activated alumina stabilized with silica.  This catalyst may be made by immersing the carrier in a solution formed by mixing ammonium tungstate solution and nickel nitrate solution (the ratio of NiO to WO3 being between 0.1:1 and 2:1); the impregnated carrier is then drained, and calcined in the usual manner.  Crude petroleum is introduced into distillation tower 2 where it is distilled at atmospheric pressure, the components boiling below 670 DEG  F.  The bottoms from tower 2 are fed to tower where distillation is effected at a pressure between 10 and 50 mm. to take overhead a gas oil having a boiling-range between about 670 DEG and 1030 DEG  F. (corrected to normal pressure).  This heavy gas oil is combined with desulphurized heavy gas oil from tower 12; and the mixture is subjected to cat.-cracking in unit 6.  The effluent from unit 6 is distilled under atmospheric pressure in tower 8, from which gasoline is taken off overhead while heavy cycle stock is withdrawn from the base.  This cycle stock is returned to unit 6, ot removed from the system.  The bottoms from vacuum-tower 4 are combined with light cycle stock taken off from the side of tower 8, and the mixture is hydrosulphurized and hydrocracked in unit 10.  In an example, a catalyst containing 3 per cent Ni (as oxide) and 9 per cent W (as oxide) deposited on activated Al2O3 and stabilized with SiO2 was employed in unit 10; the temperature being maintained at about 835 DEG  F. and the pressure at 1000 p.s.i.g.  The oil was maintained on-stream at a space-velocity of 0.5 for 16 hours, the proportion of hydrogen used being 16 M.S.C.F./B.  The effluent from unit 10 is distilled under atmospheric pressure in tower 12.  Gasoline is withdrawn from the head of tower 12, light gas oil is taken off as an upper side-stream, and heavy gas oil is obtained as a lower side-stream.
