Title: Method of recovering oil from a subsurface formation
Inventor: ALEXANDER JOHN DONALD
IPC: E21B43/243
Filed: 1965-06-30
Abstract: 1,089,621. Wells &c. CONTINENTAL OIL CO. June 30, 1965, No. 27763/65. Heading E1F. Oil is recovered from an underground formation traversed by an injection well and a recovery well by gradually heating the formation from the injection well towards the recovery well by injecting through the injection well a gas having a temperature between the vapourization temperature of the formation water and the coking temperature of the oil, continuing the injection until the oil reaches its oxidization temperature so that the gas, or oxygen subsequently injected, causes the oil to slowly oxidize and to ignite at a distance from the injection well to form a combustion front, driving the front towards the recovery well, and recovering the oil from the recovery well. Air is first passed from the injection well to the recovery well then the air is heated by a heater in the injection well and forced through the formation at 200‹F for 5 days, at 300‹ F for 3 days, at 400‹ F for 2 days and 600‹ F for 5 days. After the combustion front is formed the injection of the heated air is continued to drive the oil to the recovery well, the temperature of the air being raised to the coking temperature of the oil. In a modification nitrogen or an inert gas is injected until the temperature of the formation is sufficient to oxidize the oil and form a combustion front and then oxygen is supplied for the rest of the process.

Title: Process for the production of iron or steel from ores in a furnace
Inventor: AULD JAMES BEATTIE
IPC: C21B13/00
Filed: 1966-06-22
Abstract: Iron ore is melted and reduced in a furnace to which a carbonaceous material (such as a liquid hydrocarbon) and an oxidant are also charged. A part of the carbonaceous material is charged into or on to the bath, while the remainder is introduced into the space above the bath either together with or separatley from the oxidant.  This latter portion may be of different composition, as its sulphur content is of less importance, and its supply rate may be regulated in accordance with the temperature of the refractory lining of the furnace.  The effluent gases may be used to pre-reduce the ore and subsequently to preheat the carbonaceous fuel and/or oxidant, or may be burnt and used to preheat the charge materials.  The process is preferably carried out in a furnace inclined at up to 40 degrees to the horizontal and rotating at at least 6 revolutions per minute.

Abstract: 535,736. Cables. PYROTENAX, Ltd., and CLOTHIER, G. D. Oct. 16, 1939, No. 27984. [Class 36] A sealing device for the end of a cable, particularly one having pulverulent mineral insulation, comprises a clamping member B, for example of brass, formed as a threadcutting die B which is applied to the cable-end and rotated, so cutting a thread in the metal sheath C and securing the device to the cable. The thread may be such as to fit over the cable at its outer end B<3>, the diameter thereafter decreasing progressively or in steps. The member B may be integral with an insulating body portion or may be connected to the body portion by a screw-threaded collar, but as shown, it is separate from the body portion and spun, swaged, or riveted over to form an internal flange engaging a flange A<1> on the body A which may be of steatite. Flared apertures A<3> in the body receive the cores D which are provided with flexible tubes F to prevent kinking where they emerge from the fillet A<4> and shrouding tube E. The device as a whole may be located in a gland H. The threads may be cut in the member by a taper or parallel tap, the taper being produced in the latter case by reamering the crests of the thread. Before applying the device to the cable-end, hot or cold sealing compound is moulded over the latter or into the cavity G, and the surplus extruded through aperture B<4> in the member when screwing home. Cold sealing, with plastic compound, is done immediately after stripping the cable-end. A suitable compound for hot sealing incorporates solid fibre particles, for example as described in Specification 534,692. As sealing compound for extra high temperatures, a glazing flux or mixture may be poured into the cavity G in granular or plastic state. A steatite clamping member is referred to also.

Title: Improvements in and relating to the production of ketonic alcohols
IPC: C07C45/72
Filed: 1927-10-21
Abstract: 308,285. Nobel Industries, Ltd., (Du Pont de Nemours & Co., E. I.). Oct. 21,1927. Ketonic alcohols; diacetone alcohol.-In preparing ketonic alcohols by the polymerization of aliphatic ketones in the presence of an alkaline polymerizing agent, the polymerizing agent is used in suspension in an inert liquid hydrocarbon which is miscible with the ketone; sutable hydrocarbons are benzene, toluene, xylene, solvent naphtha, and gasoline. An inert solid diluent such as kieselguhr may be present in the suspension. The examples describe the preparation of diacetone alcohol from acetone with the use as polymerizing agents of suspensions in benzene of caustic potash alone and with kieselguhr. The reaction is carried out at a low temperature and the product is purified by neutralization followed by distillation. The presence in the product of a small amount of hydrocarbon such as xylene is not objectionable in certain applications, such as the manufacture of nitrocellulose compositions.

Abstract: 894,329. Refrigerating. FERGUSON, J. F. Oct. 26, 1960 [Aug. 13, 1960], No. 28106/60. Class 29. In refrigerating apparatus having a fan 14 forcing air through a trunking 11 containing an evaporator 12, accumulation of frost on the evaporator restricts the air flow through the trunking and causes back flow through the gap 13 around fan 14 and this flow swings a trip 15 to actuate means to stop the compressor motor until the frost has melted. As shown, trip 15 carries a butterfly valve 23 in a conduit 22 leading from the trunking to a temperature sensitive control bulb 24 operating a switch in the supply circuit of the compressor motor. When the trip is swung outwards by the air back flow, it opens valve 23 and cold air flows from the trunking to affect the bulb 24 and stop the motor. In a modification, Fig. 1-3 (not shown), the trip carries a mercury switch which stops the compressor motor when the trip is swung outwards.

Title: Improvements relating to spanners and wrenches
IPC: B25B13/12
Filed: 1925-11-10
Abstract: 251,544. Arbuckle, A. Nov. 10, 1925. Sliding-jaw wrenches; jaw faces.-The sliding jaw of an adjustable wrench is advanced by a pivoted cam engaging the jaw and supported against rearward movement by means of a number of distance pieces moved under the end of a supporting rod attached by a link to the pivoted cam. The rear end of the movable jaw B is held in contact with a cam E pivoted on a stud E<1> by a spring-pressed lever C, and the jaw B is moved upwards to reduce the jaw-gap X by turning the cam E by means of a knob M moving in a curved slot N in the cover-plate. This movement of the cam E lifts a supporting rod G connected to the cam E by a link F, whereupon a number of distance-pieces H each under the influence of a U-shaped spring J are forced over to the right to occupy the space between the end of the rod G and the frame A, thus holding the jaw B against rearward movement. The travel of the rod G is greater than the upward movement of the jaw B and permits fine adjustment of the latter. For setting the jawgap X to a larger nut the distance-pieces H aremoved from under the rod G by manipulating a rod K engaging notches in the distance pieces H and fitted with knobs K<1>, K<2> moving in curved slots L in the cover-plate V.

Title: Wave-eliminator for wireless receivers
IPC: H04B1/18
Filed: 1924-12-05
Abstract: 232,877. Hutchins, M. A. Dec. 5, 1924. Undesired signals, eliminating. - Receiving apparatus is provided with means for eliminating undesired signals, comprising an auxiliary circuit connected in parallel to the main tuning circuit and consisting of a coil C and variable condenser B tuned to the undesired wavelength; and a switch S bv which a fixed condenser or condensers A1, A2 may be connected in series or in parallel to the main tuning circuit, so that the limits of the tuning range of the latter may be unaffected. The aerial is connected at A and the earth wire at E, whilst the main tuning circuit is connected across the terminals F, G. When the undesired waves are longer than the desired waves, the auxiliary circuit BC presents an inductive reactance to the shorter desired waves. The circuit BC therefore decreases the wavelength of the whole system; and this effect is neutralized by placing the switch S in its lower position so as to connect the condenser A2 in parallel with tuning circuit F, G. When the switch S is in its upper position, the condenser A1 is connected in series between the aerial and the terminal F of the tuner F, G so as to neutralize the effect of the circuit BC when the latter is tuned to eliminate waves shorter than the desired waves. The circuit BC mav also be used as a vernier tuning-device.
