Patent GB-605215-A (GB)
Title: Improvements in or relating to the manufacture of agglomerated products from refractory materials
IPC: C04B35/00
Filed: 1945-12-07
Abstract: Agglomerated products of refractory material are prepared by fusing the material, subjecting it to rapid cooling so as to prevent the formation of large crystals, crushing the products so as to obtain a mixture of granules and fine powder, agglomerating the mixture under pressure, and fining.  Cooling of the fused material may be obtained by allowing the material to fall on to a rotating disc on to which a spray of water is directed.  The materials treated are the oxides of magnesium, silicon, zirconium, chromium, aluminium, calcium, barium, or beryllium alone or in a mixture.

Patent GB-332635-A (GB)
Abstract: 332,635. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). April 22, 1929. Acetaldehyde is prepared by passing a mixture of acetylene and steam over a catalytic mass free from water of hydration, and comprising aluminium oxide activated by one or more dehydrogenating catalysts. As suitable dehydrogenating catalysts the following are mentionedcompounds of the metals of the second group of the periodic table such as cadmium or zinc oxides or sulphides, or mixtures thereof with chromates, tungstates, or molybdates, or anhydrides of these acids, for example ZnO-WO3, ZnO.Mo03, cad. mium molybdate, zinc tungstate, phosphate, or chromate. Other particularly suitable catalytic masses are ZnO-WO3-Al2O3, ZnMoO3-Al2O3' zinc tungstate-Al2O3 or zinc phosphate-Al2O3. The temperature of working is generally between 150‹ and 500‹ C., and the acetylene may be used in a concentrated or diluted form, e.g. in admixture with hydrogen, nitrogen, ethylene, or carbon dioxide. A number of examples are given in which the following catalysts are used, (1) nickel oxide (or cobalt oxide) and aluminium oxide on pumice stone; (2) copper sulphide (or cobalt sulphide) and aluminium oxide on pumice stone; (3) zinc, cadmium, or iron sulphide and calcined alumina on pumice stone; (4) cobalt selenide and alumina on pumice stone; (5) copper, cobalt or nickel oxide and alumina on pumice granules; (6) zinc, cadmium or copper oxide and alumina on pumice; (7) zinc or cadmium phosphate and aluminium oxide on pumice; (8) cadmium or zinc tungstate and aluminium oxide on pumice granules.

IPC: G03B1/12
Filed: 1954-11-18
Abstract: 762,739. Clockwork mechanisms. STEATITMAGNESIA AKT.-GES. Nov. 18, 1954, No. 33456/54. Class 10. [Also in Group XXIV] In a clockwork mechanism for driving a film camera comprising a driving transmission gearing and a driving spring which can be wound by pulling a flexible element secured to a rotatable drum against the action of a return spring the means for winding the driving spring comprises a winding transmission gearing and a silent ratchet gear in the form of a pawl secured to the drum and engaging with a notched wheel connected with the winding transmission gearing, the driving transmission gearing being automatically disconnected from the driving spring during winding by an automatic clutch device. The clockwork mechanism shown comprises winding tape and drum 9, 13, the latter being freely rotatable about a stationary spindle 15 upon which is also mounted in a freely rotatable manner a hub carrying a notched wheel 14 and a gear-wheel 10. Rotation of this gear-wheel effects through wheels 11, 12, 28 winding of the driving spring 6 within the barrel 7. A pawl 17 is pivotally mounted on the drum 13 and during " winding '' rotation of the latter is held in engagement with a notch of the wheel 14 by a hairpin spring 16 which is so mounted on the spindle 15 that relative angular movement between the spring 16 and the spindle is made difficult. The tape 9 is re-wound on the drum through the action of a return spring therein, the outer end of the spring 16 holding the pawl 17 out of engagement with the wheel 14 during this re-winding. The drive to the camera from the wheel 28 is effected through a coiled spring one-way clutch which comprises two pinions 18, 19, with respective hubs 20, 21, freely mounted on a spindle 23 and connected by a helical spring 22 such that the latter is tightened about the hubs on rotation of the spring barrel in the direction opposite to the arrow shown thereon to thus establish a positive connection between the pinions 18, 19, and is loosened about the hubs on rotation of the spring barrel 7 in the winding direction.

IPC: H01F27/00
Filed: 1953-12-02
Abstract: 738,147. Inductors. COLLINS RADIO CO. Dec. 2, 1953, No. 33507/53. Class 38 (2). A high-frequency variable inductor has the core constructed so that any changes in the permeability of the core which would occur due to changes in temperature thereof are compensated irrespective of the position of the core relative to the winding element of the inductor. A variable inductor comprises a coil 13 through which, by means of a lead-screw 14, is moved a core member 17 to vary the inductance thereof. The core is constructed of two longitudinally disposed portions 18, 19 of powdered magnetic material, the adjacent ends of which have axial openings 21, 22 therein. Into these openings are forced threaded adaptors 23, 24 of a non- magnetic material, the threaded openings of which accommodate the threaded ends 26, 27 of a coupling member 28 also of non-magnetic material. Thus the two parts 18, 19 of the core are arranged with an air gap between them of adjustable length, the materials of the core and coupling elements being chosen to have such coefficients of expansion that any increase in permeability of the magnetic core due to increase in temperature is offset by a variation in the length of the air gap between the two magnetic portions.

In a process for removing hydrogen sulphide and ammonia from coke-oven gas, effluent from an ammonia scrubber and condensate from the gas coolers, and possibly also condensate from the compressor used to compress the partly purified gas, are introduced into the collecting main of the coke-oven producing the gas, liquor from the collecting main is detarred and used to scrub the coke-oven gas after the gas has been cooled, the gas flow velocity in the scrubber being between 1 and 5 m./sec., the gas from this scrubber is then compressed, e.g. to between 5 and 20 atmospheres, cooled and scrubbed with the effluent liquor from the first scrubbing stages maintaining a gas flow velocity between 1 and 5 m./sec., and finally the gas is scrubbed with fresh water to remove any remaining ammonia, the resulting liquor being returned to the collecting main. The detarred collecting main liquor may be divided into two portions, one of which is fed directly to the second stage scrubbing. Ammoniacal liquor containing little carbon dioxide may be fed to the second stage scrubbing, the liquor being obtained from a middle section of an ammonia still distilling the effluent liquor from the second stage scrubbing or from the vapours leaving such a still. The second stage scrubbing is preferably carried out at temperatures below 10‹ C.

As shown, submerged walls 19, (20) parallel to the side walls 16 of the tank give side compartments in which the molten metal is cooled by boxes 26, 27 and a central compartment in which the molten metal is heated by a submerged heater 28 to maintain the molten metal at the required temperatures. The space above the metal bath 12 is similarly divided by walls 21, 22 extending to close to the bath 12 and the side compartments are cooled by pipes 24, 25 and the central area heated by elements 23. In addition to the normal protective gas through feed pipes (13) in the head space, the side and central compartments may be further separated by a protective gas curtain from a pipe 31 extending along the upper partition walls 21, 22. At the end of the high temperature zone, coolers 29 may be provided to assist the gradual cooling of the whole glass ribbon to the temperature of about 600‹ C. at which it can be removed from the tank 11. Edge rollers 30 may have driven frictional contact with the cooled edges to assist in advancing the ribbon.
