Filed: 1917-10-04
Abstract: 121,975. Drakes, Ltd., and Drake, J. W. Oct. 4, 1917. Hydrogen. - Gas retorts are combined with producers in such a way that the plant will produce either coal gas, water gas, producer gas or any desired combination of these, the coal gas retorts being heated by the combustion of gases formed in the producers, or simply by the heat of the gases. The retorts may be charged with iron ore or iron, and hydrogen may be produced by passing steam through the heated mass, water gas being used to reduce the ore if required. As shown, the apparatus comprises two sets of combined horizontal retorts 3, 3<a> connected to vertical retorts 2, 2<a> arranged in a combustion chamber 4 in a setting W, at the base of which are arranged two gas producers 7, 7<a>, the products of which pass bv way of flues b, 6<1> separated by a baffle 11 and soot chamber 12 to one or other of two flues c, c<1> connected respectively to the chamber 4, and to a common chamber 15 leading by way of valves 17, pipes 16, f to the retorts 3, 3<a>. Dampers 14 control the passage of the gases in the flues c, c', and adjacent dampers may be connected together and simultaneously controlled by cam and lever, or electrically - operated or automatically - controlled mechanism governed by thermostats. The air for the combustion chambers 4 is supplied by regenerative flues 6, and is controlled by a valve. In place of the baffles 11 checker work may be employed, and this may act as a recuperator. The chamber 15 may be dispensed with and each producer may have a separate valved connexion to the inside and outside of the retort working in conjunction with it. The shape of the retorts may be varied, and two vertical retorts may connect with a common horizontal one, or inclined retorts may be used.

Title: Process for preparing a stable bitumen dispersion and for its use in the production of cement-bitumen grouts
IPC: C08L95/00
Filed: 1938-05-14
Abstract: 514,747. Bituminous emulsion compositions. COLAS PRODUCTS, Ltd., BLOTT, J. F. T., and RAWLINSON, J. A. May 14, 1938, No. 14424. [Class 22] [Also in Group III] Stable bituminous emulsions, suitable for making cement-bitumen grouts, are made by treating an initial bitumen dispersion made for example with a soap, e.g., naphthenic acid or rosin soap, and stabilized with casein or other protein substance, with formaldehyde, main-. taining at a high temperature for an extended period, then cooling down and finally adding alkali carbonate, preferably sodium carbonate. If the initial emulsion is stabilized with an alkali-peptized casein, this alkali is neutralized during or after emulsification by diffusion from the bitumen of a suitable organic acid added prior to dispersion, or by the addition of a mineral or organic acid to the dispersion. According to an example, bitumen of 200 penetration is mixed with naphthenic acid and emulsified in a 2 per cent. casein solution containing N/16 caustic potash, the potash just neutralizing the naphthenic acid. The naphthenic acid should be selected from the products of refining a light fraction of the distillation products of mineral oil; it should have a relatively low molecular weight and a high acid value. If the naphthenic acid gives an unsatisfactory product, the rate of set of the cementbitumen mix may be controlled by variation of the alkali concentration used in making the casein solution. Increased alkali concentration gives a finer dispersion and retards the setting of the cement mixes. This emulsion is stabilized by adding 0.6 per cent. by weight of 40 per cent. formaldehyde while still hot, and maintaining this temperature for 24-48 hours. After cooling, about 5 per cent. by weight of anhydrous sodium carbonate is added, and variation in the amount added controls the setting properties of the finished mix. The final emulsion contains about 45 per cent. of bitumen, and a suitable grout contains 1 cwt. of cement and 12 gallons of the above dispersion, i.e. about 33 per cent. of bitumen.

IPC: F16H57/038
Filed: 1952-06-09
Abstract: 704,445. Change-speed gear. FALK CORPORATION. June 9, 1952, No. 14474/52. Class 80 (2) Variable ratio speed reducing gearing comprises a driven shaft 15, Fig. 1, carrying a gear 26 meshing a gear 27 on a shaft 28, a second shaft 34, Fig. 2, parallel to the shaft 28, being drivingly connected thereto by interchangeable pick-off gears 32, 33. As shown, the shaft 34 is driven from a shaft 16 through a reduction train 47, 48 housed in a detachable cartridge 41; this cartridge can be replaced by alternative cartridges containing gear trains giving two or three stages of speed reduction, Figs. 9a, 9b (not shown). The gearing is contained in a rectangular casing 10, provided with mounting pads 14 by which it can be secured to a wall. floor, ceiling &c, with the driven shaft 15 horizontal or vertical, as required, the cssing acting as a reservoir for oil o; to prevent the oil leaking out past the shaft 15 when the gearing is in the Fig. 1 position with this shaft projecting downwardly, the casing is provided with an inwardly projecting tubular flange 23, the upper edge of which is above the oil level. The cartridge 41 has a circular mounting flange 44, Fig. 11, with respect to which the shaft 16 is eccentric, so that by rotation of the cartridge through 180 degrees when the gearbox is inverted from the Fig. 1 to' the Fig. 11 position, the shaft 16 is kept above the level of the oil, loss of which is thus prevented. When it is required that the driven shaft should, be horizontal, the cartridge 41 can be rotated either clockwise or anti-clockwise through 90 degrees, from the Fig. 11 position' shown, for the same purpose, such rotation necessitating changing the gear 48 for one of a smaller diameter for anti-clockwise rotation, and for one of a larger diameter for clockwise rotation. The gears 26 and 32, 33 are reached through readily detachable parts 19, 35 respectively.

Abstract: 1,015,671. Rope grips. COAL INDUSTRY (PATENTS) Ltd. May 11, 1962 [April 21, 1961], No. 14540/61. Heading F2X. In a device for connecting a load to a travelling rope, the rope grip comprises at least one jaw which is capable of sliding up and down relatively to a guide and is subjected to wedging action so that by upward movement relatively to the guide it can grip the rope and by downward movement relatively to the guide it can release the rope. In Figs. 2 and 3 (not shown) of the drawings accompanying the Provisional Specification, two plates 10, 11 support a loadcarrying bush 12 located between them and have secured to their ends two guides 14, 15 which are open at the top and bottom and in each of which is arranged a pair of jaws 16, 17. The jaws 16, 17 are arranged loosely in the guides 14, 15 and are constrained to move up and down together relative to the guide by pins 18 and 19, thereby forming a wedge-like assembly. The jaws 16, 17 may be hinged together at their upper ends, the pin 19 then being omitted. Secured to the plate 11 are spindles 20 on which are mounted rollers 21. When the device is running on support rails near to the travelling rope of a ropeway, the jaws 16, 17 do not grip the rope, but when the rollers run off the end of the rails the rope enters the jaws 16, 17 causing upward movement thereof in the guides 14, 15 and hence a wedging action so that the jaws 16, 17 grip the rope. In a modification, shown in Fig. 2 of the drawings accompanying the Complete Specification, the jaws 16, 17 are urged apart by springs 32 and the jaws carry a shoe 33 which is adapted to cooperate with a release rail.

Patent GB-681934-A (GB)
Title: Improved process for the hydration of olefines
IPC: C07C29/06
Filed: 1950-06-12
Abstract: Alcohols are made by bringing olefines in the liquid phase, into intimate contact with a solution of sulphuric acid, the treatment taking place in parallel currents until the concentration of alcohol has grown to a value such that the speed of hydration falls below the optimum speed, and then in counter-current in order to finish the extraction of the olefines. The process is based on the discovery that except for a brief period of inhibition and a brief period at the end of the reaction the speed of hydration remains practically constant regardless of the alcohol concentration in the solution and the olefine content of the liquid hydrocarbons.  Graphs are provided to illustrate this discovery and to show the concentrations of reactants in an illustration where a reaction vat continuously receives the olefinic mixture of liquified hydrocarbons and sulphuric acid solution which after reaction are passed to a separator the aqueous phase from which is distilled as described below to remove alcohols and provide acid for recycling and for washing olefines from the hydrocarbon phase after its alcohol concentration has been adjusted to ensure a high speed of hydration by mixing with used acid containing alcohol.  The hydrolysis of the sulphuric ester and separation of the alcohol require the use of acid of the highest possible concentration compatible with the direct distillation of the hydrating solution without previous dilution, the temperature should be as high as possible and the alcohol should be rapidly withdrawn from contact with the acid.  These conditions are obtained when the crude aqueous product is passed to the top of a fractionation column and a quantity of water added to make up for that lost during hydrolysis and by azeotropic distillation.  The alcohol is vaporized and passed to the centre of a second column which, heated at its base, permits the isolation of the alcohol, as an azeotrope with water, from small quantities of by-products, the distillation being effected in the absence of acid which is recovered from the base of the first column.  Heat for the first column may be applied as superheated steam which supplied at the bottom may take the place of the make-up water and render unnecessary the provision of heaters which are liable to corrosion.  Hot-water from the second column may be used for steam raising.  Impurities may be removed from the acid before recycling by filtering through an active earth and is advisable to prevent an increased production of by-products.  In examples (1) a mixture of propane and propylene and (2) a mixture of butanes and butenes are contacted in the reaction vat of the above illustration with 70 and 50 per cent H2SO4, respectively, and after processing as above indicated yield isopropanol and tert.-butanol. Specification 676,353 is referred to.
