Patent GB-698332-A (GB)
Title: Improvements in or relating to the refining and catalytic cracking of hydrocarbons
Inventor: LIEN ARTHUR PHILIP
IPC: C10G21/08
Filed: 1950-07-04
Abstract: Hydrocarbons heavier than gasoline are partially desulphurized by subjecting them to solvent extraction with about 0.1-2 volumes (based on the hydrocarbons) of liquid hydrogen fluoride at about 50-150 DEG F, and the raffinate is employed as feedstock in a catalytic cracking process employing a silica-alumina catalyst. The raffinate has substantially the same 10-80 per cent distillation temperatures as the original hydrocarbons, contains only those sulphur compounds which are not readily adsorbed on the silica-alumina catalyst, and yields, on cracking, a gasoline of low sulphur content with minimum formation of coke.  The solvent extraction may also remove other objectionable components such as polycyclic aromatic hydrocarbons, while traces of HF present in the raffinate serve to activate the silica-alumina catalyst.  According to a modification of the process, the solvent extraction may be carried out at about 150-400 DEG F, whereby at least a portion of the sulphur compounds is converted into hydrogen sulphide.  In examples, West Texas gas oil is subjected to the process, using Shper Filtrol ("Filtrol" being a Registered Trade Mark) as the silica-alumina catalyst.  Apparatus for carrying out the process is described.

Title: Improvements in or relating to power operated devices for recocking or reloading automatic guns
IPC: F41A7/04
Filed: 1941-12-30
Abstract: 556,520. Automatic guns. BENDIX AVIATION CORPORATION. Dec. 30, 1941, No. 16804. Convention date, Dec. 26, 1940. [Class 92 (ii)] Relates to hydraulically-operated piston and cylinder devices 20 for automatically recocking and recharging automatic guns by operating on the usual cocking knob in the event of a gun jamb. According to the invention, the valve 18 controlling the admission of pressure to the device 20 is in the event of failure to fire operated electrically after a time delay controlled by an electromagnetic slow-release device 26. The invention is shown applied to the control of a pair of guns 21 the cocking devices 20 of which are fed through valves 18 by pressure and exhaust pipe-lines 16, 15 in circuit with a pump 12 accumulator 14 and reservoir 10. The valves 18 are electromagnetically operated as described in Specification 556,547, [Group XXIX], by the electric circuits shown. The circuits include an ignition switch 24, a safety switch 40 and a trigger switch 42 controlling the trigger actuator 44. On closing the ignition switch 24, current passes to relay 26 through normally closed switch 31 to a switch 28, normally closed when the breech is closed and through switch 30 normally closed when the gun is not firing. This circuit energises the solenoid 27 of the relay 26 to operate a bell crank 29 and keep open the switch 34 controlling the solenoid of valve 18. To fire the guns switches 40, 42 are closed, actuator 44 is operated to release the breech block and switch 30 opens. The continuance of fire causes switch 38 to open and close to energise solenoid 27 to keep switch 34 open. If a gun jambs switch 38 remains open, solenoid 27 de-energises after a certain delay and switch 34 closes to cause valve 18 to open. If the trigger switch has been opened after charging starts, the switch 28 is opened by the breech block to allow the charging operation to continue. Switch 28 can be opened manually by a ring 23 when feeding a new belt to the gun. Charging can also be effected by manually operating the switch 31 which also prevents "runaway fire". After a predetermined number of charging operations, a counter 300 cuts off the current to valve 18. Fig. 3 shows the arrangement of the switches 28, 38 in relation to the cocking knob 184 and charging cylinder 20. A piston extension 168 operates the counter button 194 and the breech bolt sear 176. The charging cylinder is attached to the gun by quick-release means 212. In a modification a single master-valve 18 controls the supply of pressure to selector valves at each gun.

Title: Improvements in or relating to circuit arrangements for simultaneously stabilizing asawtooth current through a coil and a high voltage supply
IPC: H04N3/185
Filed: 1961-05-10
Abstract: 946,595. Automatic regulation. PHILIPS ELECTRICAL INDUSTRIES Ltd. May 10,1961 [May 13, 1960], No. 17028/61. Headings G3R and G3X. [Also in Division H3] In a circuit for simultaneously generating a sawtooth current in a coil 8 and a high voltage supply Vh, the sawtooth current is stabilized by variation of current in the output stage 1 under control of the primary voltage of the output transformer. The high voltage is stabilized by a variable ballast element such as 24, controlled by a signal derived from the high voltage secondary winding 10. Fig. 3 shows a line output stage for television equipment in which a valve 1 or transistor drives current through deflection coils 8 connected to the primary of the output transformer. A diode 7 and two capacitors 5 1 , 5 2  form an h.t. boosting circuit. The current in valve 1 under control of waveform 2 results in parabolic waveforms 33, 38 across capacitors 5 1 , 5 2 , giving an S-shaped sweep waveform in deflection coils 8. The primary waveform is rectified by valve 34 and capacitor 35 the rectified voltage being dependent on the voltage across capacitor 5 2  which is connected to the grid of valve 34. The rectified voltage is fed via resistor 21 to the grid of valve 1 and used to control the anode current and hence the amplitude of the sawtooth current in coils 8. The cathode voltage of valve 34 is stabilized by tube 37. The stabilizing circuit 20 may be replaced by a voltage dependent resistor as described in Specification 890, 805. E.H.T. voltage regulation. The flyback voltage across the secondary winding 10 is rectified by valve 11 and supplies e.h.t. voltage to the cathode-ray tube 9. The e.h.t. voltage is stabilized against variation in cathode-ray tube beam current by a triode or pentode 24, the grid voltage of which is controlled by the voltage developed across resistor 25 through which the beam current passes. The control voltage is smoothed at 30, 31, 32. In Fig. 1 (not shown) the cathode of valve 24 is connected to the positive supply Vb. Specifications 795,415, 849,980, 891,486 and 898,625 also are referred to.
