Title: Improvements in or relating to brake operating gear for motor vehicles
IPC: B60T11/04
Filed: 1926-05-04
Abstract: 267,745. Maxted, H. P. May 4, 1926. Force-transmitting mechanism. - Four-wheel brake-operating mechanism for motor vehicles. comprises a cross-shaft adapted to rotate the operating members of two equalizing or power-distributing devices each comprising pair of meshed toothed sectors or interconnected links or a single floating link pivoted to the operating member and connected to a front and rear brake rod on the same side of the vehicle. The arrangement may be sucli that unequal pressures are applied to the front and rear brakes and that the ratio of these pressures may vary during the .application of the brakes. The arrangement. shown in Figs. 2, 4 comprises a transverse rock shaft 3 to which the pedal is connected by an arm 14 and link 4. Equalizers provided at each end of the shaft for operating the front and rear brakes on the corresponding side of the vehicle, comprise geared toothed sectors 12 pivoted at 11 to arms secured to the shaft ends and connected at 13 by pull rods 7, 8 to the brakes on the corresponding side of the vehicle. The points of con nection 13 of the pull rods to the sectors 12 may be so arranged that the initial stresses applied to the rods 7. 8 may be equal or greater on either rod with a varying ratio of charge subsequently. Thus these points may be displaced to unequal extents on opposite sides of the line joining the pivots 11 of the sectors so that the pressure applied to the rear brakes is at first greater and gradually becomes equal to and then less than that applied to the front brakes. Fig. 6 shows a modified equalizer in which the toothed sectors are replaced by a pair of liners 12 pivoted at 11 on the arms of the cross-shaft and connected together by a pin-and-slot 15, 16, or the ends of the levers may instead be connected by a link. Fig. 12 shows a further form of equalizer comprising a floating lever 16 connected at 17<1> to an arm 17 on the cross-shaft 3. An adjustable screw stop 18 may be provided on the arm 17 for engagement with the lever 16 so that at a certain stage in the application, the floating action of the lever is destroyed and a greater final pressure is applied to either the front or rear brakes according to the distances of the pivots 13 of the pull rods from the shaft 3. Specification 263,525 is referred to.

Title: Improvements in and relating to the concentration of acetic acid solution
IPC: C07C51/48
Filed: 1927-05-04
Abstract: 295,238. Carpmael, W., (I. G. Farbenindustrie Akt.-Ges.). May 4, 1927. Acetic acid. - In the extraction of acetic acid from its aqueous solutions. organic, bases not attacked by concentrated acetic acid, such as quinoline, quinaldine, dimethylaniline, diethylaniline and the like or mixtures thereof are employed as solvents. The extraction may be effected in the vapour phase or in the cold. In the former case the aqueous acid is heated in a vessel a, the vapour passing by a tube b to a column c which is provided with filling material or perforated shelves. The solvent is supplied to the top of the column and the concentrated acid solution is collected in a vessel d. Water vapour leaves the column at the top and is condensed in the usual manner, any solvent carried over being collected in a siphon tube s and returned to the column, and any remaining solvent is recovered from the aqueous distillate. When the extraction is effected in the cold, the quantity of water remaining in the extract may be reduced by adding a salt such as common. salt or by adding to the solvent substances insoluble in water such as benzene, chlorofrom. trichlorethylene, ethylene chloride, or carbon tetrachloride. The addition of these liquids renders the final distillation of acetic acid from the extract more efficient, the water usually distilling first with the added liquid while the acetic acid is to some extent held bound by the organic base. Specification 218,271 is referred to.

Abstract: 676,916. Moulding sulphur and sand compositions. ROMEI, R., and CIONI, G. Feb. 28, 1951 [May 15, 1950], No. 12062/50. Classes 70 and 87(ii) A process for the production of moulded articles comprises the steps of adding together sulphur and silver sand, heating the mixture at the boiling point of sulphur for at least half an hour, mixing them thoroughly until evenly distributed in the mixture, placing the resultant mixture in a mould whilst still hot, and allowing it to cool until hardened whilst still in the mould. Colouring powders of a kind unaffected by the heat may be added, vegetable black being especially suitable. If the proportions of powdered sulphur and silver sand are 80 : 100 the resultant product, yellowish-green in colour, is suitable for articles such as vases. Equal proportions result in a stronger but more expensive article. A mottled appearance can be given to the finished product by adding pumice powder to the mixture, the quantity of which should be small, 4 or 5 parts to 10 parts of silver sand. The surface finish on the moulded article can be varied according to the type of finish on the mould.

Title: Improvements in and relating to synthesis of ammonia
IPC: C01C1/04
Filed: 1922-05-01
Abstract: Ammonia is synthesized from its elements by the use of a catalyst which comprises a carbonitrogenous compound, such as the cyanamide of magnesium or beryllium.  The catalyst may be prepared by treating a magnesium or beryllium compound, such as the carbonate, with ammonia gas at an elevated temperature and preferably under pressure, and then consists of the corresponding cyanamide.  Advantageously, a finely-divided metal, such as iron, cobalt, manganese, thorium or uranium, or a compound thereof, such as the oxide, hydroxide, carbonate, acetate or oxalate, is mixed in any proportions with an aqueous paste of the magnesium or beryllium compound and the product dried in the form of lumps before subjection to the ammonia treatment.  An example is given of the preparation of a catalytic material from a mixture of magnesium and manganese carbonates.  Using a catalyst of this kind, the synthesis of ammonia takes place at temperatures of 400-500 DEG  C. under pressures of 15-100 atmospheres.ALSO:Magnesium and beryllium cyanamides are prepared by treating a magnesium or beryllium compound, such as the carbonate, with ammonia gas at an elevated temperature and preferably under pressure.

Title: A process for producing coloured pictures from photographic prints
IPC: G03C11/18
Filed: 1928-04-26
Abstract: 289,411. Farmer, E. H. April 26, 1927, [Convention date]. Drawings to Specification. Colouring; catalype, osotype, and contact processes.-A process of producing coloured prints consists in preparing a photographic silver print containing a minimum of colloid vehicle on a support adapted to give a water-colour drawing effect, painting different parts of this print with an excess of different coloured pigments combined with a vehicle containing galatinous material, such as gelatin or glue but excluding gum and casein, subjecting the pigmented vehicle to the action of a tanning agent which reacts on the vehicle in the presence of the photographic image and hardens the vehicle so that the pigments are fixed on the print in proportion to the density of the image, and dissolving away the surplus unhardened vehicle and the pigment carried thereby as with warm water. The under-print may be made as a weak print on plain paper, celluloid &c. sensitized with a thin coating of gelatin and bromide or chloride of silver, and may be developed as with metol-hydroquinone. Ground pigments or water-colours, mixed for example with an aqueous solution of glue, or of gelatin which has been partially hardened with chrome alum, are painted on while the under-print is still damp and preferably warm. The tanning bath may contain bromide, bichromate and ferricyanide of potash, acetic acid, alcohol and water; this bath, in a concentrated form, may be added to the paints before they are applied to the silver print, but it is preferably employed in dilute form after colouring. The surplus unhardened gelatin and its pigment content are removed with warm water, and the print is finally fixed in hypo. The silver under-print may remain, or may be bleached, or entirely removed. The Specification as open to inspection under Sect. 91 (3) (a) states also that if a finished and dried under-print is used, it is bleached with a solution of ferricyanide and bromide of potash, and redeveloped before colouring. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements relating to coating with metals by dipping
IPC: C23C2/38
Filed: 1931-04-27
Abstract: 385,971. Coating with metals. SENDZIMIR, T. K., 24, Yuen Ming Yuen Road, Shanghai, China, and BOSTROEM, T. J., 38, Avenue de la Gare, Meudon, Seine-et-Oise, France. April 27, 1931, No. 12361. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 28, 1931.] [Class 82 (ii).] In a process for coating sheets, wire, pipes, or other articles with metal by dipping in which the article is preheated to annealing temperature and protected from oxidation during transfer from the preheating means to the coating bath, the article is subjected to a gradual cooling from annealing temperature to a temperature of about 50-100‹ C. above the melting-point of the coating metal before immersion in the coating bath. Preferably the preheating means, which may be a furnace or a molten bath, is heated at a point near to the entry end so that the article has cooled to the desired temperature before leaving the preheating means. In a method of coating wire according to the invention the preheating means consists of a bath C containing molten lead L heated by electrodes D immersed in the lead and situated nearer the entry end of the bath. A bath F for the coating metal, e.g. zinc, is separated from the bath C by a partition N and a continuous layer M of pulverized coal, charcoal, &c. covers the lead L, the partition N, and the zinc J. The wire B is drawn through the air-excluding layer M into the lead where it is heated to annealing temperature and gradually cooled. It passes over the partition N into the bath F without passing out of the airexcluding layer M, the excess heat of the wire maintaining the zinc in contact therewith in a molten state so that no external heating of the zinc bath is necessary. The zinc in contact with the walls of the vessel F is therefore cool and may solidify, so that the life of the vessel F is prolonged. Pickling or electrolytic cleaning of the articles prior to preheating is necessary only in special cases, e.g. if the articles are coated with lime or other calcium compound. Reference has been directed by the Comptroller to Specifications 19696/07, [Class 82, Metals and alloys], and 287,201, [Class 82 (ii), Washing granular &c.].
