Patent GB-964855-A (GB)
Title: A process for the production of sheet materials from polyamide fibres
IPC: D21H13/26
Filed: 1963-01-25
Abstract: Sheet materials are made from polyamide fibres by treating the fibres with natural tanning agents containing hydroxyl groups, partial ethers or esters thereof or synthetic polyhydroxy compounds having a tanning action, dispersing the treated fibres in water, casting the dispersion to form a web, dehydrating, drying and consolidating the product.  Polyamides referred to are those from caprolactam and from the salt of adipic acid and hexamethylene diamine.  Tanning agents referred to are gallotannins, oak bark tanning substances, catechol tanning substances, partially etherified and esterified tannins, polyhydroxy-benzophenones, polyhydroxyanthraquinones; polyhydroxynaphthoquinones and condensation products thereof with agents such as formaldehyde, and digallic acid.  The fibres can be treated by conducting a tow through the tanning solution, and then stretching and washing, or they can be treated with tanning solutions after stretching or cutting to length.  The fibres are preferably not dried after treatment with the tanning agent, but merely separated from the treatment liquor by centrifuging.  The products can be calendered hot or cold, or sprayed in a dry condition with impregnating agents or binding resins, or drawn through solutions or emulsions of such materials, e.g. a copolyamide.  They can be consolidated by heat and pressure, when they contain a proportion of polyamide fibres which have a lower melting point than the other fibres, using a temperature slightly above the melting point of the fibres of lower melting point.  In one example untreated fibres are added to an aqueous suspension of treated fibres, this suspension made into paper, and the paper is calendered at the melting point of the untreated fibres.  Specification 868,651 is referred to.

Title: Improvements in brush lifting mechanism for electric motors
IPC: H01R39/42
Filed: 1943-03-01
Abstract: 569,351. Brush-gear for electric motors. JACK & HEINTZ, Inc. March 1, 1943, No. 3355. Convention date, July 11, 1941. [Class 35] A removable brush-carrying and -lifting unit for a motor, more particularly a motor for impulse starters of aircraft engines, comprises a plate 16 bolted to the commutator casing 8 of the machine and carrying insulated arms 17 terminating in contacts 18 which are clamped to binding posts 49 in a terminal box to which current for the brushes 28 is supplied. The brushes are mounted in holders 25, arranged in pairs and pivoted to the arms 17 at 26, springs 35 urging the brushes towards the commutator 4. Insulated rollers 30, engaging lugs 29 on the brush holders, are carried by toggle levers 48 which normally hold the brushes off the commutator under the action of a compression spring 41 arranged between the fixed core 39a and movable core 38a of a solenoid 38, the levers being pivoted to the movable core. Energisation of the solenoid winding removes the spring pressure on the toggle joint and allows the brush springs 35 to move the brushes into contact with the commutator.

Abstract: 975,430. Road vehicle suspensions. METALASTIK Ltd. Jan. 7, 1963 [Jan. 29, 1962], No. 3355/62. Heading B7D. A pair of tandem axles 10, 11, which may be fixed axles or axle casings which may enclose driving gear, are connected on each side by hemispherical pivot bearings 19 to a longitudinal balance beam 15 or leaf spring assembly which, in the laden condition, extends horizontally. Centrally disposed control links 29 are pivotally connected to brackets attached to a transverse member 30 of the vehicle frame and to brackets 27 extending from the axle casing, or to the casing itself in the case of a driven axle. Each hemispherical bearing 19 comprises partspherical elements 20 and 21 attached to brackets 18 depending from the axle casings, and to the balance beam, respectively, and an interposed resilient member 22. The balance beams 15, or spring assemblies, are connected by brackets 37 to a pair of links 32, 33, which are connected to brackets 39 depending from the chassis frame 12. The connections of the links 32 and 33 to the brackets 37 and 39 may include resilient bushes 40, 38, Fig. 2, the upper of which 40 is long enough to withstand transverse forces, or may be replaced by a pair of spaced apart shorter bushes or by a single short bush in which case Panhard rods or triangular rods are connected between the axle casings and the chassis frame. In modifications, Figs. 2 and 3, the upper mountings of the links 32 and 33 include conical and spherical bearings 50 and 52 respectively, each of which include resilient members. Alternatively, the links 32 and 33 may be pin jointed. The links 32 and 33 are inclined so that lines through the centres of their pivots intersect the vertical transverse plane through the centre of the suspension T at a point C in, or slightly offset from, a horizontal plane H containing the centres of the bearings 19 and which is the virtual pivot centre of the beam 15 or spring assembly. The bearings of the rods 29 may include resilient bushes.

Patent GB-489967-A (GB)
Title: Manufacture of tanning agents
IPC: C14C3/22
Filed: 1937-02-08
Abstract: Tanning-agents are obtained by sulphonating a mixture or a reaction product of a phenol and colophony (or a material containing colophony), and removing electrolytes from the crude sulphonation product by washing it with an aqueous solution of an alkali or ammonium salt of 2-10 per cent strength.  In the examples: (1) a fused mixture of phenol and pine resin is treated with oleum, and the crude sulphonation product is kneaded twice with water and then repeatedly with an ammonium sulphate solution of 8 per cent strength until the washing liquor is only faintly acid; (2) an ester obtained from colophony and tricresol is treated with sulphuric acid monohydrate and the crude sulphonation product is stirred repeatedly with 6 per cent sodium-chloride solution; (3) a fused mixture of colophony and resorcinol is treated with oleum, and the product is washed with 8 per cent ammoniumoxalate solution until it is neutral; (4) a mixture of hercules resin and o-chlorophenol is sulphonated with sulphuric acid monohydrate and the product is washed with 4-5 per cent sodium-chloride solution.  The Specification as open to inspection under Sect. 91 covers generally the removal of adhering electrolytes from the crude products obtained by sulphonating a mixture or a reaction product of a phenol and a natural resin, and indicates that the removal of the electrolytes may also be effected (1) by dialysis, (2) by salting-out, and (3) by liming the crude product and filtering, whereby a filtrate containing the calcium salt of the product is obtained; this may then be treated with soda or sulphuric acid, filtered from the precipitated calcium salt, and the filtrate evaporated.  The following examples are included: (1) a mixture of Swedish resin (talloel) and b -naphthol is treated with sulphuric acid, and the product is washed with 6-7 per cent sodium chloride solution; (2) an esterification product of abietic acid and 4 : 41-dihydroxydiphenyldimethylmethane is treated with sulphuric acid, and the product is dissolved in water and salted out with 30 per cent sodiumchloride solution; (3) talloel is melted with a mixture of phenol homologues distilling at 200-230 DEG  C., and the product is sulphonated with oleum; the crude sulphonation product is then purified by salting-out, as described in the preceding example; (4) a fused mixture of colophony and commercial xylenol is sulphonated with sulphuric acid, and the product is kneaded first with water and then repeatedly with 5 per cent sodium chloride solution.  This subject-matter does not appear in the Specification as accepted.
