Title: Improvements in or relating to a method of regenerating a platinum-alumina catalyst
IPC: B01J23/96
Filed: 1954-11-29
Abstract: Non-fluoride-containing platinum-alumina reforming catalyst prepared according to Specification 735,390 is regenerated by burning off carbonaceous material with a mixture of inert gases and not more than 1.5 per cent by volume of free oxygen at 500-930 DEG  F. and a pressure not exceeding 500 p.s.i.g. while keeping the water vapour partial pressure of the exit gases below 50 mm. of mercury, then oxidizing the platinum by maintaining the catalyst at 800-950 DEG  F. in a dry atmosphere having a partial pressure of free oxygen of 0.2-3 atmospheres for at least 0.5 hour, and reducing the oxidized platinum to the metallic state. The catalyst may be in the form of a fixed, moving, or fluidized bed; with a plurality of reactors, one reactor may be regenerated at a time.  After the reforming period the catalyst is cooled and purged of combustible gas, e.g. by reducing the heat to the process and stopping the hydrocarbon feed while continuing to recycle gas; the pressure may then be reduced to a partial vacuum and the catalyst purged with flue gas or other inert gas.  The pressure is then increased, e.g. to 100-150 p.s.i.g., and air is added to the inert gas which is dried and recirculated.  The temperature and oxygen content of the gas are controlled to give the desired burning temperature.  The second oxidation stage may be carried out at 930-950 DEG  F. for 5-30 hours; the required oxygen partial pressure is preferably attained by compressing dry air. After completing the oxidation, the catalyst is cooled and reduced with a hydrogen-containing gas, e.g. at 40 p.s.i.g.  In examples, catalysts prepared according to Example V of Specification 735,390 are regenerated.  The first burning stage is carried out (a) with nitrogen containing 1 or 1.5 per cent oxygen at atmospheric pressure; (b) with nitrogen containing 0.35 per cent oxygen at a total pressure of 400 p.s.i.g.; or (c) with nitrogen containing 0.7 per cent oxygen at 30 p.s.i.g. increasing to 130 p.s.i.g.  The second oxidation stage is carried out (a) with undiluted air at atmospheric pressure; (b) with pure dry oxygen at 20 p.s.i.g.; or (c) with air at 130 or 150 p.s.i.g.  Reference has been directed by the Comptroller to Specifications 735,145 and 748,777.
Patent GB-173507-A (GB)
Title: Manufacture of a remedy for malignant tumor
IPC: A61K33/04
Filed: 1921-12-22
Abstract: Metallic selenides or tellurides are prepared in the colloidal state, or in colloidal solution, by the action of selenium or tellurium compounds on metallic compounds in presence or absence of a protective colloid.  The latter, if used, may be gelatin, proteids, gum arabic, starch, dextrin, &c., or the water-soluble alkyl derivatives of polysaccharides.  These last are of value in that their aqueous solutions coagulate on warming, carrying down with them other colloid substances present, and redissolve on cooling.  This property allows the selenides or tellurides to be purified by washing.  In an example, 300-700 parts of 1 per cent auric chloride solution are mixed with 200 parts of a 3 to 10 per cent solution of a water-soluble alkyl derivative of a polysaccharide, such as methyl or ethyl cellulose, and the mixture treated with hydrogen selenide.  The olive-brown hydrosol of gold selenide is warmed to 50-80 DEG  C., when the alkyl cellulose coagulates, carrying the metallic compound with it.  The precipitate is filtered in a hot water funnel and washed.  It may then be dried, or dissolved in cold water.  Other methods of purification, such as dialysis, may be employed. Selenides or tellurides of silver, mercury, copper, tin, iridium, platinum, palladium, osmium, and other metals may be prepared in the same way, or other compounds of selenium or tellurium may replace the hydrogen compound.

Title: Method of manufacturing thermally insulated pipes
Inventor: LEHNERT GUENTHER
IPC: B29C39/18
Filed: 1969-07-09
Abstract: 1,221,152. Making pipes. KABEL-UND METALLWERKE GUTEHOFFNUNGSHUTTE A.G. 9 July, 1969 [8 Aug., 1968], No. 34539/69. Heading B3A. [Also in Division F2] A method of making a thermally insulated tube comprises surrounding an inner tube with a strip coated with a self-foaming plastics foam forming material, forming a metal strip into a split tube to surround both the inner tube and the coated strip, welding the edges of the metal strip to form an outer tube and corrugating the outer tube. The strip which is coated may be a metal strip of thickness between 0À02 and 0À7 mm., particularly a steel strip between 0À05 and 0À4 mm. thickness, which may be welded to form a tube or left with an open seam. In the latter case the foam may enter the space between the strip and the corrugated outer tube. The coated strip may be of crepe paper, particularly where foaming does not occur till after the outer tube has been corrugated, whereupon the crepe paper is pressed against the outer tube thus ensuring the space between the inner and outer tubes is completely filled with foam. The pipe may be used for the transport of hot or cold fluids or as a cable conduit for superconducting cables when the inner tube is filled with liquid helium and the foam is a polyamide foam. The outer tube may be provided with a sheath of corrosion-resistant plastics material.

Abstract: 377,078. Aerials. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. Dec. 14, 1931, No. 34662. Convention date, Dec. 12, 1930. [Class 40 (v).] Relates to systems wherein circularly or elliptically polarized radiation is transmitted or received by two aerials 1, 2, Fig. 1, arranged at right-angles and coupled to a common source 4, one aerial being tuned slightly above and the other slightly below the working frequency, so that the aerial currents are relatively dephased by the desired amount. According to the invention, detuning is effected by introducing slight differences in the length or thickness of the aerial wire ; or by altering the insulator capacity. With horizontal aerials, the radiation is particularly suitable for broadcasting, the amplitude of the field being uniform throughout the horizontal plane. Several aerials may be arranged to form a beam system, and may be backed by reflectors. Fig. 3 shows an aerial of the Beverage type fitted with mutually perpendicular transverse radiators, relatively detuned and spaced apart by half a wave-length. Radiation may be confined substantially to the horizontal plane by arranging several rotating systems in a vertical tier as shown in Fig. 5. In the horizontal arrangement shown in Fig. 6, the current phases in the various limbs are such as to give practically no vertical radiation. Specifications 306,418, [Class 40 (v), Wireless signalling &c.], and 342,060 are referred to.

Title: Method of making filament-wound pressure vessels
IPC: B29C53/76
Filed: 1961-09-27
Abstract: 988,582. Winding filaments on hollow bodies. B. F. GOODRICH CO. Sept. 27, 1961 [Oct. 5, 1960], No. 34700/61. Heading B8G. A former 10, Fig. 1, that is to be wound with filamentary material 34, has its longitudinal axis 13 inclined to a fixed predetermined winding plane F such that the plane F intersects the end portions 28a, 28b of the former and also intersects said axis 13 at a location between said end portions. The former 10 is rotated about an axis 24, normal to the winding plane F, so that the material 34 is wrapped in endwise loops from one end portion to the other end portion along the shortest available path between these end portions. In addition, the former is rotated about its axis 13 for a fraction of a complete rotation each time an end portion of the former is presented to the filamentary material. As shown, the intermittent motion about the axis 13 is effected by a drive mechanism 17 operated intermittently by limit switches 13 located under a rotating table 20 and tripped periodically by lugs 54 mounted on the table. The apparatus also includes traversing means 70 to 75, Fig. 3 (not shown), whereby circumferential windings can be applied to the former over the lengthwise windings L, the former 10 being rotated continuously about its longitudinal axis during the formation of the circumferential windings. The material 34 is a tape of weftless strands of filamentary material (see magnified section in Fig. 1), such as glass fibre filaments, the strands being encapsulated in a moulding resin. The function of the resin is to enable the strands to be bonded one to another in the finished article so that the wall of the latter is of continuous material. The strands of the tape are individually tensioned. In Fig. 5 (not shown) the strand 34 is supported by one end 64 of a pivoted arm 60, the movement of the arm 60 being controlled by a cam 66 such that as the former 10 is rotated about the axis 24 the end 64 of the arm 60 maintains the strand 34 thereon at a position close to the former 10. The former 10, Fig. 10 (not shown), may be of plaster or metal or a plastic having a low melting temperature so that the former can be easily destroyed to effect its removal from the wound assembly. In Fig. 10, the former 10 has an outer rubber layer 31 that has been cut away at one point to accommodate an apertured reinforcing patch 77 that is then coated with a suitable adhesive or resin. Thereafter, one or more layers of the lengthwise winding may be wound on the former over the patch 77. Additional similar patches may be applied to the windings concentrically with the first patch between successive layers of the windings, and an outermost patch (not shown) is applied after the winding is complete. The finished article is then treated to harden the resin and the portions of the windings traversing the central openings of the patches is cut away to provide an opening into the article.

The streams of air are directed through nozzles 19, 21 in headers 18, 20 which substantially surround the drums, and the material is transferred from the conveyer to the drum 16, from the drum 16 to the drum 17, and from drum 17 to a conveyer 39 by directing air streams towards the material.  The material enters the housing through rollers 26, 27 forming an air seal and is directed by air streams from nozzles 28, 30, 31 on to the drum 16 which rotates in an anti-clockwise direction, heated air from the nozzles 19 passing through and about the material to remove moisture therefrom, which air passes into the centre of the drum and axially out of the annular space between the drum and header.  The material is transferred to the drum 17 by an air stream from a nozzle 35 formed in a channel 34 having nozzles 36, 37 for drying air between the drums and is removed from the drum 17 by air from nozzles 40, 41, 42, 45 on to the conveyer 39 which carries the material through sealing rollers 46, 47 into a cooling chamber 48.  The cooling chamber comprises headers 49, 50 having nozzles 51 for cool air drawn in through a duct 52.  The speed of the conveyer 39 is lower than the speed at which the material is fed to the drying chamber to avoid tension and accommodate shrinkage and the material on leaving the conveyer 39 passes around a roller 66 to control the speed of subsequent equipment such as a folder (not shown).  Blowers 53, 54 driven by motors 55, 56 which supply heated air to the headers 18, 20 are mounted in the housing above and below the cooling chamber and receive air from chambers at opposite sides of the drums, a small amount of air being exhausted through a duct 64 which is replaced by air supplied through ducts which is discharged over the bearings of the blowers.

Title: Means for regulating combustion in furnaces
IPC: F23N5/00
Filed: 1922-12-28
Abstract: 204,982. Babcock & Wilcox, Ltd., (Deutsche Babcock-&-Wilcox Dampfkessel- Werke Akt.-Ges.). Dec. 28, 1922. Air and fuel supply, regulating.-The supply of air to beneath the grate of a furnace is regulated in accordance with the proportion of CO2 in the furnace gases and, in the case of boiler furnaces, the fuel supply may also be regulated in accordance with the pressure in the boiler. As shown in the Figure, air is supplied to the rear of the grate in regulated quantities by a number of shutters 6 arranged beneath chambers formed by partitions 5, the arms 7 of the shutters decreasing in length towards the rear so that the shutters are opened or closed to a varying amount when the actuating-rod 8 is operated by the piston 10 working in the cylinder 11. Pressure water is supplied to the cylinder 11 through a three-way cock 14 operated by the armature 15, an electromagnet 19, the winding 18 of which is connected through a battery 20 and relays 21, 22 to a selenium cell S. When the CO2 content of the furnace gases exceeds a certain amount, the pointer 35 of the measuring- apparatus uncovers to a greater extent an opening 34 in a screen 33, so that a greater portion of the selenium coil S is exposed to the source of light 36 and its resistance is decreased. The current strength in the winding 18 is therefore increased and 'the armature 15 is attracted against the force of a spring, the cock 14 is opened and pressure water is supplied to the cylinder 11 to operate the shutters 6 and increase the supply of air to the furnace. Should the supply of air be insufficient to correct the CO2 content, the pointer of the measuring-apparatus exposes a larger portion of the selenium cell to the source of light and the current strength of the circuit is further increased. This causes the armature of the relav 22 to be attracted and to close a circuit in which is a battery 27 and bell 28, the latter being rung to warn the stoker that the furnace needs attention. When the CO2 content decreases too much, the selenium cell will receive less light and the armature 15 will be actuated by its spring to close the cock 14 and allow the pressure water to flow to the drain pipe 17, the piston 10 being moved to the left by a balance weight 12 to close the shutters 6. If the CO2 content drops below a permissible limit, the armature of the relay'21 is retracted by its spring to close the bell circuit and ring the bell 28 to warn the attendant. The battery 27 and bell 28 are also in circuit with wiring 29, 32 and contacts 30 which are engaged by the arm 31 of the piston rod 9 when the piston reaches each end of its stroke.
