Title: Production of combustible gas from hydrocarbons
IPC: C01B3/38
Filed: 1951-03-16
Abstract: 698,640. Generating oil gas. HUMPHREYS & GLASGOW, Ltd., and WILLIAMS, N. H. March 17, 1952 [March 16, 1951], No. 6372/51.. Class 55(ii) In a cyclic process for making combustible gas by the catalytic reaction at elevated termperatures of hydrocarbons such as oils or tars, or gaseous hydrocarbons such as natural gas or refinery gas, with an oxidizing gas comprising steam and/or carbon dioxide and may be air, each make' period wherein the hydrocarbon and steam &c., is passed through the heated catalyst mass is followed by a heating period when air is supplied to burn off the deposited carbon and to burn heating fuel when necessary and surplus heat generated during this period is recovered by passing part of the hot gases resulting from the carbon combustion through a waste heat boiler, the remainder being passed through a regenerator used in the make' period for preheating the oxidizing gas. The apparatus consists of a steam preheating regenerator 5, a chamber 1 containing a catalyst mass consisting, for example, of a mixture of nickel and iron oxides supported on magnesia or alumina, an air preheating regenerator 8 and a waste heat boiler 11. During the 'make' period, steam from pipe 13 enters the previously heated regenerator 5, is superheated therein and passes into chamber 1 in the top of which it meets a spray of hydrocarbon oil from a pipe 15. The steam and oil react in the catalyst mass to produce permanent gas which passes up through the regenerator, 8, heating the checkerbrick therein and discharges to storage through pipe 18. If gaseous hydrocarbons are to be treated they are admitted to the base of regenerator 5 with the steam. At the end of the make period, the apparatus is purged with steam and air is admitted to the regenerator 8 through a valve 20, the air being preheated in the regenerator and then passing up through chamber 1 where it burns off the carbon deposited in the catalyst during the make' and thus heats the catalyst. The hot combustion gases leave chamber 1 through a pipe 3 and pass into regenerator 5, part of the gases being withdrawn through a valve 9 before they enter the regenerator or through a valve 12 after they have traversed a part thereof and passed through the waste heat boiler 11. The gases which pass wholly through the regenerator 5 discharge through a pipe 14 and a stack valve 21. If the combustion of the carbon deposits does not provide sufficient heat, a fuel such as oil, supplied from nozzles 25 and 26, may be burnt in the apparatus to make up the deficiency.

Abstract: 774,474. High-frequency supply systems for space discharge devices. TOUVET, G. Jan. 12, 1951, No. 6511/53. Divided out of 774,471, Class 38 (4). In a circuit embodying a discharge tube 1 having internal electrodes between which the discharge passes and which are heated by the discharge without preheating and a source of R.F. voltage for starting and exciting the tube, the impedance between the electrodes is substantially devoid of a conductive component when the tube is cold but is substantially matched to the impedance of the source through an impedance matching coupling when the tube is operative. As shown, the tube is at the end of a quarter-wave section of transmission line 21 inductively coupled to a tank circuit 20 of a power amplifier 4. When the tube is non-conducting the line 21 is effectively open-ended and applies a high oscillatory voltage to the tube which starts the discharge and the standing wave is then substantially reduced. In another embodiment, a tank circuit is arranged at the end of a long length of coaxial line and the tube is connected across part of the tank circuit at points where impedance matching obtains when the tube carries current. Specification 774,475 is referred to.

Title: Manufacture of terephthalic acid-glycol esters suitable for polycondensation
IPC: C08G63/78
Filed: 1956-03-02
Abstract: Terephthalic acid glycol ester products, suitable for polycondensation, are obtained by heating terephthalic acid and ethylene glycol, in approximately the molecular proportions necessary to produce the bis-glycol ester, in a closed vessel to 210-260 DEG C. for a time varying according to the temperature from 3 hours to 30 minutes, then cooling the batch to a temperature below the boiling-point of the ethylene glycol, allowing the water produced in the reaction to be blown off as steam, forcing glycol, pre-heated to about 180 DEG C., into the reaction vessel in a quantity to make up the molecular proportion of glycol to terephthalic acid to 14.5 to 18 : 1, closing the vessel again and further heating the contents to 220-260 DEG  C. until the desired reaction has taken place.  The products obtained consist mainly of the bis-glycol ester with only small and unobjectionable proportions of the p  mono-glycol ester, esters of diglycol, and condensation products. In the isolation of the product, the excess of glycol may be distilled off under vacuum at about 120 DEG  C. and the still fluid reaction product may be poured into water at 80 DEG C.  After cooling to 50 DEG C. the separated condensation product is removed by filtration for further working up, and from the mother liquor the monomeric terephthalic acid glycol ester is caused to crystallize by cooling to about 10 DEG C. and isolated by filtration.  The condensation product removed after the hot water treatment may be converted into monomeric glycol terephthalate by heating it to 230 DEG  C. in a closed vessel with 5-7 times the quantity of glycol. The filtrate from the final filtration may be used as the water for treating a further batch of the product.  After being used several times this liquid may be heated to 240-250 DEG C. in a closed vessel so as to hydrolyse dissolved esters to terephthalic acid.

Title: Improved rotary pump
IPC: F04C14/22
Filed: 1951-03-21
Abstract: 687,998. Rotary pumps. GENERAL MOTORS CORPORATION. March 21, 1951 [April 1, 1950], No. 6728/51. Class 110(ii) A pump having sliding-vanes 66 within an adjustable stator 62, to vary the pump capacity, is provided with large inlet and outlet passages 22, 30 leading respectively to narrow ports 24, 29 the ends of which are tapered off in the form of ramps to effect a gradual build up and release of pressure as the vanes pass by. A spring 68, Fig. 4 (not shown), forces the stator 62 upwards to give the greatest eccentricity between the stator and rotor 64 for starting up purposes. A piston valve 40 has its interior 42 open to the pump discharge pressure which, at first, also communicates with chambers 70, 72 at one end of the stator, and a chamber 74 at the other end acting in the same direction as the spring 68. As the vanes pass over a ramp 96, of the outlet passage 29, fluid fills passages 29, 26 and bore 42 building up pressure against a valve spring 48. When the pump pressure exceeds that demanded, e.g. by a servo system being supplied, the valve is forced upwards to admit further fluid to the chambers 70, 72 through port 44 and a passage 34. and to release the fluid supply from the chamber 74 by cutting off a port 35, the stator 62 then moving to decrease the pump capacity. According to the position of the valve 40, pressure fluid is directed solely to chamber 74; solely to chamber 72 and 70 or, in the usual case to all chambers 72, 70, 74. A passage 76 connects chambers 70, 72 when the stator is at maximum eccentricity. A restricted passage 78 connects the discharge side of the pump with the chamber 74. The backing spring 48, on the valve, is adjustable through a nut 52. Side rings 100, 102 support the vanes. Drain passages 82, 84 discharge fluid which leaks through packing 104. An annular passage 86 communicates with passages 88, 90 to supply lubricant to the moving parts when the stator 62 is moved sufficiently to uncover the passage 90 leading to the pump delivery. The passages 88, 90 are designed to produce a lubricating pressure of about 20 lbs. per sq. inch from a pump delivery pressure of 80 1bs. per sq. inch.

Abstract: 662,789. Photo-electric exposure control. KODAK, Ltd. March 11, 1949 [March 11, 1948], No. 6735/49. Addition to 660,099. Class 40 (iii). [Also in Group XX] In a modification of the method claimed in the parent Specification for making colour prints on colour photographic material wherein the integrated light is adjusted so that, if employed to expose the light-sensitive material, the exposed material after processing is grey, to avoid over-correction when printing from records having one predominant colour, the integrated light consists of the printing light transmitted by the negative together with some light coming direct from the light source (or from another light whose colour composition is varied in the same way as the printing light), the diluting light being excluded from the transmitted printing beam when printing on the light-sensitive material. As shown, light from a lamp 12 passing through a colour negative 11 and light from the same lamp reflected by a mirror 25 is received by a photo-electric cell 20, which is covered by one of the blue, green and red filters 17 ... 19 carried by the rotatable disc 13, and the cell current is brought to a standard value for each colour by adjusting the lamp intensity, printing of the negative on a colour sensitive sheet 22 being effected separately for each colour, with the lamp appropriately adjusted in intensity, through a filter 14 ... 16 carried by the disc 13 and of a transmission related to that covering the cell during adjustment of the lamp, the light reflected by the mirror 25 being meanwhile cut off as by closing the diaphragm 26, which determines the amount of diluting light employed while adjusting the lamp. If necessary the colour composition of the diluting light may be adjusted by filters adjacent the diaphragm 26.
