Title: Improvements in the recovery of liquid and gaseous unsaturated hydrocarbons from asphaltic oils and oil residues
IPC: C10G11/00
Filed: 1950-01-18
Abstract: <PICT:0671556/III/1> Asphaltic and resin - containing oils and oil residues are cracked to give inter alia liquid aromatic and gaseous unsaturated hydrocarbons by passing the oils downwards together with catalysts or inert porous substances through a vertical reactor at a rising temperature, a temperature of 350 DEG -450 DEG C. being maintained in the upper part of the reactor and a temperature of 600 DEG -700 DEG C. in the lower part of the reactor, gaseous hydrocarbons formed in the upper part being removed before they can enter the lower part and gaseous hydrocarbons formed in the lower part being removed separately from or concurrently with the contact material.  The gaseous hydrocarbons formed in the upper part of the reactor may be catalytically cracked in a separate vessel.  As described regenerated granular contact material is introduced into a reactor b at a1 and oil is introduced at a.  The gases first formed are taken off by a duct c shielded by guard plates d and catalytically cracked in a vessel e at 400 DEG -550 DEG C.  The gases formed in the lower part of the reactor are similarly taken off at f condensed at s and separated at g.  Contact material with solid residue deposited thereon is taken off at u and regenerated at the top of the reactor b by the introduction of air at p and hot gases at o. Purge steam is introduced into the reactor at r1, r2 and r3.  The requisite temperature at the upper part of the reactor may be derived from the regenerated contact material by preheating the oil feed. Highly heated gases such as hydrogen, nitrogen, water-gas or steam may also be introduced to supply additional heat.  The temperature in the lower part of the reactor may be maintained by heat applied externally or internally by the introduction of hot gases or regenerated contact material.  The outlet at the lower end of the reactor may be perforated to separate liquid and solid discharge products.  An example is given of the cracking in a 20 litre reactor of an Arabian petroleum which has been topped from the fraction boiling up to 350 DEG  C. the residence time of the contact material (clay sherds) being 120 minutes and of the oil 10.5 seconds, and the temperatures in the upper and lower parts of the reactor being 400 DEG C. and 600 DEG C. respectively.  An analysis of the products is given.

[Class 38 (iv)] [Also in Group XXIX] Aircraft ailerons are controlled jointly by signals from a direction gyro and a gyro vertical so that a stabilized straight flight may be followed or a given change of heading effected by manual displacement of the direction gyro about the vertical axis after locking of the inner gimbal. As shown, Fig. 1, to effect automatic control of the craft in azimuth and bank the ailerons are set by the pneumatically positioned piston 43 controlled by the valve 39 adjustable by the armature 23 of a polarized relay. The armature 23 carries coils 22, 50, of which the former is energized by the resultant of the outputs from the signal generators 17, 28 of the direction gyro and the gyro vertical 2 respectively, while the latter is energized from the aileron follow-up signal so as to oppose the effect of 22. The heading departure signal remains constant for departures beyond a predetermined limit. The knob 4 may be used to lock the inner gimbal 1 and to rotate the gyro to set a fresh course. To control the craft in pitch, Fig. 2, not shown, the elevators are positioned by a polarized relay energized by a pitch signal from 24 and a follow-up signal from the elevator.

Abstract: 638,281. Automatic current or voltage control systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 15, 1947, No. 1408. [Class 38 (iv)] [Also in Group XL (a)] In a voltage or current stabilizing apparatus, the variations of voltage or current from a predetermined value cause deflection of the beam 6 of a discharge tube 3 under the control of a magnetic field so as to vary the voltage at the output 5 of the tube this output being utilized to restore the voltage or current to the predetermined value. As shown, coils 2 in series with the load current and a control valve 8, are mounted on a permanent magnet 1, the arrangement being such that normally a field is created by the coils 2 which balances that due to the magnet. Upon any variation 'of the load current the beam 6 is deflected and the potentials of the two electrodes 5 are varied to control a degenerative D.C. amplifier 7, the output from which controls the impedance of the valve 8,' i.e. the impedance between the supply unit 9 and the load terminals 10 in a sense to correct for variations of the voltage or current conditions at terminals 10.

Title: Improvements in or relating to rotary abrasive tools
Inventor: SWAN RICHARD JAMES
IPC: B24D9/00
Filed: 1952-01-24
Abstract: 714,944. Abrasive tools. ENGIS, Ltd. Jan. 23, 1953 [Jan 24, 1952], No. 2006/52. Class 60 A rotary abrasive tool consisting of closely spaced brushes 24, between which abrasive strips 27 extend, the inner portions of the strips being secured to and coiled around anchorages 26 to form a single spool, has an external control member 61 which may be set to drive reduction gearing 41, 42 for rotating the spool with respect to the brush assembly. The anchorages consist of a series of pins mounted on a ring 31 rotatable on a boss 32 and secured by a circlip 33. The free ends of the pins are engaged by an annular series of holes in a flange 35 integral with a worm wheel 41 mounted on ball bearings 38, 39. To rotate the spool, the member 61, which is in the form of a hard rubber roller, is advanced so that it engages an eccentrically situated member 48 once during each revolution of the tool. This member 48 is thus oscillated about the shaft of a worm 42 to cause a pawl 47 to impart intermittent rotation to the worm through a ratchet wheel 46 secured to the worm shaft. The member 61 is withdrawn when the required lengths of abrasive strips have been fed outwardly between the brushes. Rubber stops 54, 55 limit the travel of the member 48 and a second pawl (not shown), constrains the ratchet wheel to rotate in one direction only. The inner ends of the brushes are encased in metal strips 25 which are of dovetailed cross section and adapted to slide endwise into correspondingly shaped holders 18. The latter are secured by screws 19 to a front plate 17 welded to a hub portion 16 and have lugs 21 to engage recesses in a back plate 23. To load the tool with abrasive strips, a nut 12 and a flanged tube 36 carrying the gear assembly and the back plate 23 are unscrewed, the anchor loops of the abrasive strips are passed over the pins 26, the strips fed between the brushes, and the front plate 17 rotated while holding the anchor pins stationary so that the abrasive strips are wound into a core. The boss 11 is secured to the tool spindle by grub screws 14, 15. A balance weight (not shown) is secured to the plate 23 to eliminate vibration.

Abstract: 469,188. Valves for water heaters. MAXOL HEATERS, Ltd., DAVIS, H., and LOMAX, W. Jan. 23, 1936, No. 2121. [Class 135] The gas valve D of a gas-heated water boiler is adapted to be moved off its seating d<2> and held open by the pressure of the water acting on a diaphragm C<2> against a closing spring dl.

Should, however, the diaphragm c<2> become punctured the water pressure will act on a second diaphragm C<1> which will close the valve D onto a second seating d4 and cut off the gas supply from the burner A<1>. The water supply to the boiler is controlled by a main tap F and a regulating valve E.

Abstract: 829,654. Cathode-ray storage tubes. MULLARD Ltd. Jan. 21, 1957, No. 2122/57. Class 39(1). [Also in Group XL(b)] A storage tube capable of being switched from a condition of charge writing to one of charge reading with simultaneous erasure has a secondary emission target 5 upon a signal plate 6 and a secondary emission collecting electrode 7 at 300 volts relative to the earthed cathode 2. With switch 10 up, 6 is raised 50 volts above earth (i.e. above the first cross-over) and the target elements charge up positively when scanned by a modulated beam. With switch 10 down, the target is earthed and the elements are charged to voltages below the cross-over ; an unmodulated beam thus returns them to earth and generates a signal over resistor 11. The target may be a sheet of mica or a layer of magnesium fluoride barium oxide, magnesium oxide or aluminium oxide. A mesh grid 71 stretches across electrode 7 a short distance from the target. The tube is used in a circuit in which two tubes are simultaneously in the writing and reading conditions respectively, and are then simultaneously reversed (see Group XL(b)).
