Filed: 1969-07-09
Abstract: 1,220,002. Electro-forming wire. KABELUND METALLWERKE GUTEHOFFNUNGSHœTTE A.G. July 9, 1969 [Aug.10, 1968], No.34541/69. Heading C7B. Elongated metallic material, e.g. Cu wire, is produced by electro-deposition on a cathode body in the form of a spiral opened out longitudinally of the body, the length of elongated material being smoothed by external mechanical means during deposition. The cathode body is preferably a rotating roller 3 covered at least partly by the electrolyte 1, e.g. CuSO 4  solution, and provided on its surface with one or more spiral grooves 4. The roller may be made of plastics material and the bottom of the or each spiral groove metallized by insertion of a Cr-plated steel wire 5 thereinto Fig. 2, alternatively a base for the deposition may be formed by the metallised spiral upstanding portion adjoining the or each groove. The roller may be of metal, e.g. cast iron or brass, in which the spiral grooves are filled with insulating material, with the adjoining upstanding portions Crplated Fig.3. Smoothing may be effected by one or more glass balls or agates 7 guided over the spiral deposit, e.g. by being mounted on an endless chain 8. At least two cathode bodies may be employed so that Cu spirals may be pulled off (at 9) one after the other. 1,220,018, Tanning leather. FARBENFABRIKEN BAYER A.G.

Patent GB-1155095-A (GB)
Title: Rolling Mill Control System
IPC: B21B37/38
Filed: 1966-08-08
Abstract: 1,155,095. Rolling. UNITED ENG. & FOUNDRY CO. 8 Aug., 1966 [9 Aug., 1965], No. 35401/66. Headine B3M. A fluid control system for use in bending the rolls of a rolling mill permits a high fluid pressure, exerted on a roll of the mill for applying a bending force to the roll, to be quickly released and maintained at a desired lower pressure. Cylinders 32 and 33 are positioned between the projecting ends of backing rolls 15 and 16, a high pressure normally being generated in the cylinders to force pistons 27-31 outwardly in order to bend the backing rolls and hence give a controlled crown to working rolls 13 and 14. In order to allow the mill screwdown 22 to be operated without being under the hydraulic loading (or to allow roll changing) the high pressure is releasable using the control system. The cylinders are mounted in brackets which are pivoted to the mill frames, so that the cylinders can be swung clear of the rolls by cylinder assemblies 41 and 42 in order to facilitate roll removal. The fluid control system can employ oil alone, a mixture of oil and suitably treated water, or water alone, according to the degree of fire risk encountered. In a mixed system, Fig. 3, oil is used in the high pressure side, which includes an intensifier 46 connected to the cylinders 25, 26, 25a and 26a by lines 45. The low pressure side, which includes a surge tank 65 supplied from an air compressor 74, employs water. A servo controlled pump 52 supplies the intensifier 46 and hence the cylinders with oil under pressure, the pressure produced by the pump controlling the degree of bending of the rolls. To release the high pressure the low pressure side of the intensifier is drained through a line 49, and a solenoid 62 operated to drain lines 45 and 59 through a check and decompression valve 61, through a 3-way valve 64, and to the surge tank 65. The pressure in line 63 is then maintained at a desired low value by means of a regulating valve 71 disposed between a prefill pump 72 and the surge tank. In the event of roll changing an even lower pressure is necessary, in order to prevent the pistons 27-31 being forced from their cylinders. The line 63 is thus opened to line 68 by the valve 64 and a back pressure regulator valve 67. The cylinders 32 and 33 can be positioned between the work roll ends if desired, and the pressure intensifier can be replaced by a multiple plunger boiler feed pump.

Filed: 1922-12-29
Abstract: 192,053. Akt.-Ges. Brown, Boveri, et Cie. Jan. 19, 1922, [Convention date]. Low - pressure metallic- .vapour apparatus. - In a rectifier for heavy currents having a cooling dome Q above a mercury cathode K and anodes A<1>, A<2> arranged laterally with respect to the cathodes, substantially the whole of the vapour from the cathode is led by an unobstructed vertical guide tube R into the dome so that the anode spaces are almost free from vapour, and such velocity and direction are imparted to the vapour that compression of the air takes place at a point O in the dome where the suction pipe y of a preliminary vacuum pump is connected. A high vacuum pump may be necessary at starting. The tube R is made of smaller diameter than the dome and projects into the dome, so that mercury vapour passes into the dome in the form of mist and carries air along with it. Water is circulated through a cooling jacket W. Condensed mercury falls back into the cathode.
Patent GB-632182-A (GB)
Title: Improvements in or relating to catalytic reactions
IPC: B01D53/34
Filed: 1946-11-29
Abstract: The elimination of oxygen and/or hydrogen from a gaseous mixture is effected by combining oxygen with hydrogen to form water in the presence of a catalyst comprising palladium deposited on a support of aluminium oxide or zirconium dioxide.  When both hydrogen and oxygen are present in the gaseous mixture they are combined with one another.  When hydrogen only or oxygen only is present, the other is admixed with the gas.  The process is applicable to the manufacture of oxygen-free hydrogen or hydrogen-free oxygen or to the manufacture of nitrogen from the air.  It may also be applied to the production of oxygen-free argon, neon, helium, methane, ethane and carbon dioxide.  The catalyst-support may be in granular, tablet or pellet form and the aluminium oxide may be in the form of activated alumina or anhydrous aluminium oxide.  In addition to palladium, the catalyst may also contain other metals or compounds, catalytic or non-catalytic, such as the other metals of the platinum group. The reaction is initiated at room temperature and is accompanied by the evolution of heat.  Water formed in the reaction may be removed by absorbents such as activated alumina, silica gel, phosphorous pentoxide, calcium chloride, magnesium perchlorate, or by condensation.ALSO:Methane or ethane containing oxygen and/or hydrogen are purified by passing the mixture over a catalyst comprising palladium deposited on a support of aluminium oxide or zirconium dioxide, whereby the oxygen and hydrogen combine to form water. When both oxygen and hydrogen are present in the gaseous mixture they are combined with one another.  When hydrogen only or oxygen only is present, the other is admixed with the gas.

Filed: 1930-11-26
Abstract: 350,878. Back-pedalling brake and free-wheel arrangements. POIRIER, G., 28 bis, Quai Marmoutier, St.-Symphorien, Loire, France. Nov. 26, 1930, No. 35551. Convention date, Nov. 28, 1929. [Class 136 (ii).] A free-wheel and back-pedalling brake hub for tricycles, invalid carriages, &c., is adapted to enable the road wheel to be driven in the reverse direction, by the use of ratchet mechanism interposed between the cycle &c. fork and a member carrying the brake band &c., and adapted to prevent rotation of such member in the forward direction, but to allow its rotation in the backward direction, with sufficient friction to permit of the operation of the brake. The driving chainwheel 16 is mounted on a sleeve 15 having a screw thread 17 engaging a member 18, which drives the hub 11 in the forward direction (arrow F) through pawl-and-ratchet mechanism 19 permitting a freewheel action. On back-pedalling (arrow B), the member 18 is traversed by the thread 17 to engage its conical clutch part with a cup 22, which then, through a stud 24, rocks a lever 25 about its pivot 26 on a plate 27, to expand a band 31 into contact with a brake drum 32. The plate 27 is fixed to a member 28, which engages a conical member 29 fixed on the spindle 10 and carries non-rotatably a ratchet wheel 34, Figs. 1 and 3, engaging a spring-pressed pawl 35 on an arm 38, which has a ring-shaped lower end encircling the member 28 and is fixed at its upper end to the cycle fork. During back-pedalling, friction between the members 28, 29 provides a sufficiently firm anchorage for the pivot 26 of the brake lever 25 to enable the brake to be applied. The ratchet mechanism 34, 35, by allowing backward rotation of the member 28, enables the wheel to be driven in the reverse direction through the clutch 18, 22 and the brake mechanism and drum 32.
