Title: Improvements in or relating to the recovery of oil from oily sludges
IPC: C10G1/00
Filed: 1931-04-13
Abstract: Oily sludge from destructive hydrogenation is passed, under pressure and above 250 DEG  C., preferably at 350 DEG  C., through a pipe 1 into a chamber 2, the pressure being suddenly released at the valve 1a, superheated steam or other hot inert gas being introduced by nozzles 3, while the whole is heated by furnace gases passing through a jacket surrounding the vessel.  Agitators stir the sludge and the oil vapours pass of by a pipe 4, while the partially treated sludge passes by a tube 5 into a vertical vessel provided with a feed worm 6, steam jets 7, and a heated jacket. Oil vapours pass off by <PICT:0376756/III/1> pipe 8 and may pass with those in pipe 4 to the catchpot 15, maintained at 120-150 DEG  C., where heavy oils condense, the light oils and steam passing to a heated bubble tower 16, from which oil is drawn off at the base 18; the lightest fraction is condensed and separated from water in the separator 21.  The dry residues are discharged through a water seal 10.  The furnace 12 superheats steam in the coil 11, provides heating medium for the jackets, and if necessary preheats the sludge.

Abstract: 401,183. Supplying air to sunken submarines. TINNING, W., Mossband, Gretna, Carlisle. April 13, 1933, No. 11065. [Class 68 (i).] Means for supplying a sunken submarine with air from above comprises a buoy housed on the deck of the submarine and having a float-actuated air valve connected by a flexible pipe with the interior of the submarine, means for admitting water to the float chamber when the buoy is released to close the air valve while the buoy rises to the surface and means for emptying the float chamber to cause the valve to open. As shown a tank 2 is provided behind the conning tower of the vessel and a buoy 5 comprising air chamber 7 and float chamber 8 is normally held thereon by screws 33 with lock nuts 37. An air pipe 22 passes from the vessel, is coiled in an inner perforated cylinder 29 and connected to a pipe 21 passing into the float chamber of the buoy adjacent a needle valve 24 controlled by bell cranks 28 resting on a float 18. A cable 41, shorter than the air tube, also connects the buoy and the vessel. Tubes 9 extend from the air chamber of the buoy and their depending free ends are normally closed by screw-adjusted rubber pads 11. In use, the screws 33 are released from the buoy by handles 36, so admitting water to the tank 2 and the buoy floats away, water entering tubes 9 and raising float 18 to close the valve 24; at the surface, water drains from the float chamber and the valve 24 opens. In a modification, the buoy depends from a plate forming the cover of tank 2 and two air pipes 22 are provided for inlet and outlet ot air, each pipe having its needle valve 24; said cover plate may have depending threaded tubes for engagement with screws 33 and the air pipes may be coiled around a vertical cylindrical grid in the main tank 2.

Title: Improvements in underreamers
IPC: E21B10/32
Filed: 1923-04-24
Abstract: 218,774. Arbon, P. April 24, 1923. Bore - hole apparatus. - An under - reamer for drilling wells has a removable c o r e 31 located within body 1, the core receiving the lateral thrust of cutters 14 and being reversible when worn. The body is connected by bridles 2 to a sleeve 3, and the cutters slidably engage ribs on the upper parts of the bridles, and are retained in position by a head 19, having lugs 18 engaging shoulders 17. The head is forced upwards by a spring 37 acting upon a nut 26, which is adjustable on a draw bar 27 connected to the head. The cutters can slide downwards between the bridles till the shoulders 17 clear the tapered end of the core 31, whereupon they can swing inwards to allow of the passage of the reamer through the well casing. The spring returns the cutters to their operative position when they have passed below the end of the casing and may be aided by another spring located below the head 19. The sleeve 3 serves as a cage to catch a cutter should it break, and thereby obviates the neccessity of fishing operations. A liey 9 can be screwed into the end of the drawbar 27 so that the latter can be pulled downwards when the cutters are to be removed for sharpening or renewal, the head being rotated so that the lugs 18 engage recesses in the bridles and prevent the return of the head to its normal position.

Abstract: 881,620. Remote signalling. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. March 24, 1959 [April 8, 1958], No. 11131/58. Class 40 (1).  Movement of a plunger, due to dimensional changes of an object, rotates a spindle whose position is signalled to a remote indicator by a selsyn device or a potentiometer whose slider is coupled to the spindle. In the diagram movement of plunger 7 results in rotary motion of spindle 8 to which is coupled slider 9 of the potentiometer. Slider 9 is normally kept out of contact with winding 10 until a measurement is required when the slider is brought into contact with the winding by evacuating bellows 17 through pipe 27. Spindle 8 carries turbine blades 29 so that under the action of gas jets 30 or 31 the plunger may be advanced into contact with the object to be gauged or retracted to a fixed stop.

Title: Improvements in and relating to electric blanket control
IPC: H05B3/34
Filed: 1947-04-29
Abstract: 630,628. Interrupters; thermal switches. BRITISH THOMSON-HOUSTON CO., Ltd. April 29, 1947, No. 11467. Convention date, April 30, 1946. [Class 38(v)] In a device for controlling the temperature of an electric blanket, a motor-driven interrupter operates in conjunction with a bimetallic element which compensates for changes in room temperature, one adjustment being provided to vary the temperature of the blanket without affecting the rate of compensation for changes in room temperature and a second adjustment being provided to alter this rate of compensation. A motor 14 with a cam 13 oscillates a pivoted actuating arm 10, which, by means of a motion transmitting member 15, operates a pivoted contact-carrying arm 7. The position of the member 15 relative to the pivot of the arms, determines the time the contacts 5, 6 are open in relation to the time they are closed, and thus controls the average amount of energy supplied to the blanket 1. The member 15 is moved laterally between the arms 7, 10 by a bimetallic helix 16, which in unwinding as the room temperature falls, moves the member 15 to the left to increase the percentage of time that the contacts 5, 6 are closed and so compensate for the drop in room temperature. The stem 17 on which the bimetal 16 is fixed, may be turned by a lever 20 to move the member 15 to obtain a different blanket temperature without affecting the rate of compensation. The distance between the arms 7, 10 and the stem 17 may be altered by moving a lever 18 on which the stem is mounted, so as to alter the effective radius of movement of the member 15 so that for a given change in temperature the extent of the lateral movement is changed and the rate of compensation varied accordingly. Specification 610,485 is referred to.
