Patent GB-769913-A (GB)
Title: Improvements in and relating to the etching of ferrous metals
Inventor: FARRER THOMAS WILLIAM
IPC: C23C22/68
Filed: 1952-12-08
Abstract: Iron and non-stainless steels are etched by converting the metal to be removed into readily removable sulphide and oxide by direct contact with the metal of elementary sulphur in the presence of water for a period exceeding that necessary for the air-formed oxide film to be replaced by a film of sulphide.  The metal surface after removal of the sulphide and oxide is of a fine grained rough or matt character and may provide improved adhesion of protective films of paint.  The etching agent may be an aqueous suspension of 10-50 per cent by weight finely-divided sulphur.  The suspension may be prepared by shaking flowers of sulphur with water, by a precipitation reaction as between hydrogen sulphide and sulphur dioxide, with sulphur precipitated from carbon disulphide solution, by "moistening" sulphur with alcohol and then taking it into suspension with water, or by holding the sulphur in a dilute aqueous suspension of clay or other suspension stabilizing agent such as bentonite, the latter however being omitted if it is not desired to increase the electrical conductivity of the suspension.  The induction period during which the air-formed oxide is converted into sulphide and after which the action becomes rapid, can be reduced by the addition of soluble sulphides or chlorides.  The sulphur can be applied in the form of a paste, such as a thixotropic paste made from an aqueous suspension containing 5 per cent bentonite and 15 per cent sulphur, and including a soluble sulphide or chloride. The resist may be a mask of porous paper such as filter paper. The surface to be treated must first be degreased, as by electrolytic action in 1 per cent sodium carbonate.  The method can be applied to the removal of ferrous metal bases from thin films of non-ferrous metals.  For this purpose a thin film of e.g. an epoxy resin is applied to the non-ferrous film before removal of the ferrous metal base by immersion in a sulphur suspension.

Title: Improvements in the manufacture and production of adhesive and binding agents
IPC: C08F136/06
Filed: 1928-11-01
Abstract: 328,908. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Nov. 1, 1928. Adhesives.-Liquid oily polymerization products of butadiene containing no solid polymers, and suitable as adhesive and coating agents are made by heating butadiene to above 40‹ C., if desired under pressure, and stopping the process before the production of solid polymers. The pressure employed may be as much as 200 atmospheres or more. Inorganic catalysts such as finely divided metals or organic catalysts such as aliphatic or aromatic umines may be used, and a diluent may be employed, in which case isoprene may be used instead of butadiene. The oil obtained from butadiene at 150-220‹ C.. freed from volatile constituents if such be present, may be clarified by animal charcoal and is then colourless ; the oils obtained above 220‹ C. are very viscous and dry more quickly, The oils may be used to improve the adhesive power and flexibility of lacquers and the adhesive power of binding agents such as glue; the coatings may be heated below 100‹ C. to hasten the drying. In the examples (1) (2) (3) and (4) butadiene is heated in an autoclave to 200‹ C., 380‹ C., 300‹ and 135‹ C. respectively; in the third case the oil is distilled up to 140‹ C. to remove volatile constituents, and may be mixed with tricresyl phosphate and used as a lacquer which is dried at 85‹ C - the film may be taken off from the substratum, and is strong and elastic; (5) butadiene is heated with aniline benzene or cyclohexene; the aniline &c. is distilled off and the liquid product may be mixed with linseed oil with or without boiled oil, copal, and cobalt linoleate; (6) butadiene is introduced at 2 atmospheres pressure into a closed vessel containing dimethyl aniline benzene or anisol and aluminium chloride at 150‹ C., the dimethyl aniline &c. being separated from the product by distillation; (7) butadiene is added to a mixture of tetra-hydrostyrene or ether and sodium in a pressure vessel and heated to 100‹ C. ; (8) isoprene and tetrahydrostyrene are heated in a pressure vesseol at 200‹ C. Specifications 20648/12 and 156,116, [both in Class 2 (iii), Dyes &c.], are referred to. Reference has been directed by the Comptroller to Specification 29277/09, (Class 2 (iii), Dyes &c.].

Title: Improvements in or relating to the manufacture of jellies, jams and similar food products
IPC: A23L21/12
Filed: 1932-11-10
Abstract: To prevent presetting in making jams and jellies from fruit such as cranberries, blueberries, tart plums, &c., having a high content of quicksetting pectin, or from juice from such fruit, this pectin is first wholly or partially destroyed or rendered innocuous, e.g. by enzymatic action.  The enzyme used may be pectinase, or an enzyme preparation derived from Pencillium glaucum employed in solution or precipitated by means of alcohol &c. and used in solid form, and the fruit material is kept during the treatment, which takes about 12 hours, at the optimum temperature for the enzymatic action, e.g. 25-50 DEG  C.  The fruit material is preferably brought to a pH value of 3,1 to 3,5 prior to the treatment.  In preparing jam and jelly, there is added to the treated material sugar and pectin, preferably a slow setting pectin, but fruit or fruit juice from which the pectin has not been eliminated may be employed instead, and the mixture is boiled until the solid content reaches 65 per cent.  The fruit may be softened, pulped or disintegrated before treatment.

[Class 118 (ii).] In an improvement on the manoeuvre-signalling apparatus for vehicles described in Specification 319,482, [Class 118 (ii), Signals], the hand is pivotally mounted at one end of a lazytongs, one of the last inside links of which is extended beyond the pivot, its free end urging the lazy tongs to close by means of a spring. The hand 19, preferably made hollow, of celluloid or the like, and illuminated from within, is pivoted at a pin 16 to the outer links of a lazytongs 10, and is normally retained in a sleeve-like casing 5 rotatably mounted at 6 on a member 7, Fig. 1. The inner link 12 of the lazytongs 10 is fixed relative to the fixed pivot 6, and, when the casing 5 is rotated in a vertical plane, by means of a Bowden cable 22 fixed to a pulley 21 fast with the casing 5, to the position shown in Fig. 2, the lazytongs extend, the pin 16 being guided along an arm 15 pivoted at the axis 6 and secured to the casing at 15a; the hand is pushed out of the sleeve 5 and by means of a pin 20 thereon engaging with the cam end 18 of the arm 15 assumes an upward direction, Fig. 2. The casing 5 may be turned in the horizontal plane by means of a Bowden cable 23, Fig. 1, fixed to a pulley 25, the member 7 fixed to the latter being rotatably mounted in a bracket 8. The two motions of the hand 19 and sleeve 5 are effected by one actuating lever 26, Fig. 4, adapted to rotate independently two pulleys 30, 29 to which the cables 22, 23 respectively are connected, the pivot 27 of the lever being mounted in a support 28 attached to the pulley 29. Return springs 14, 24 are fitted, but may be dispensed with, in which case the outward and return movements of the signal are both effected by the Bowden cables. The bracket is preferably fitted near the driver's seat but may be fitted at any convenient position. Two or more signalling arms may be fitted for example at the sides or at the front and back of the vehicle both being operated from the same lever.
