Title: Improvements in or relating to bristle strips and bristle strip brushes
IPC: A46B13/00
Filed: 1966-02-09
Abstract: 1,072,838. Brushes. HUSQVARNA BORSTFABRIK A.B. Feb. 9, 1966 [Feb. 19, 1965], No. 5644/66. Heading A4K. In a brush strip, upstanding bristle deflecting tabs 4a, b are widely spaced to provide regular gaps at which bristles 3 can spread outwardly on either side of the channel holder, thus preventing the tabs from deflecting the wire bristles in a pronounced wave formation. Non-coincidence of the peaks and troughs of the waves of adjacent turns of strip, in a cylindrical or frusto-conical brush, is thus not critical in preventing the bristle tips from being evenly distributed in the brushing surface.

Title: 3,5-disubstituted pyrazoles
IPC: C07B61/00
Filed: 1976-02-12
Abstract: 3,5-Diphenylpyrazole, 3,5-diphenyl-4-alkylpyrazoles or 3,5-diphenyl-4-alkoxypyrazoles are prepared from the corresponding pyrazolines by catalytic dehydrogenation in an inert organic solvent. Platinum or palladium, both of which can also be supported by various substances, can be used as catalysts. The pyrazolines used as starting material can be obtained by reacting a methyl ketone, such as acetophenone or its derivatives, with a suitable aldehyde, such as benzaldehyde, in the presence of a base, to give a 1,3-disubstituted  alpha , beta -unsaturated ketone, such as chalcone or its substitution products, acidification of the resulting reaction mixture and treatment of the acidified reaction mixture with hydrazine. The compounds prepared according to the invention can be used as starting substances for the preparation of corresponding 3,5-disubstituted 1,2-dialkylpyrazolium salts, such as 1,2-dimethyl-3,5-diphenylpyrazolium methyl sulphate which, in turn, can be used as herbicides.

Title: Improvements in or relating to recording apparatus for motor vehicles
IPC: G01P1/12
Filed: 1938-02-25
Abstract: 495,308. Recording-apparatus; speedometers; taximeters. HARVEY, H. C. Feb. 25, 1938, No. 5728/37. [Classes 106 (iii) and 106 (iv)] Apparatus for testing the speedometer or taximeter of a motor vehicle comprises a pair of rollers which support and are rotated by the driving wheels of the vehicle, a driving connection from one of said rollers, and a paper strip which is moved by said driving connection. In the construction shown in Figs. 1 and 3 paper tape 12 perforated along its centre passes from a roll 11 around a toothed feed-roller 13, over a freely pivoted roller 17, through an electromagnetic marking device 18, around a second feed-roller 19 and through a slot 20 in the upper wall of the casing 10. The feedroller 13 is driven through pulley 14 and belt 15 from grooved worm wheel 22 driven through worm 21 and clutch 42, operated by lever 43, from flexible shaft 41 driven from roller 35 which with roller 36 supports and is driven by the rear driving wheels 38 of the vehicle whose front wheels 40 are supported by the ramp 39. The rollers 35, 36 may be sunk into the floor with their upper parts flush with the floor surface. A carbon ribbon 23 passing round rollers 24, 25, 26 is moved by frictional engagement with the tape 12. The electromagnetic marking device 18 is in circuit with a switch in the clutch 42, a battery 34 and a clock-actuated relay 46, and marks the tape 12 at intervals of one second. A second marking device may be used to mark the tape at one-tenth or one-fifth of a second intervals. In testing a speedometer the rear wheels are driven so that the speedometer indicates a steady value and the distance between the time marks on the tape 12 is a measure of the speed of the vehicle wheels. The distance is measured on the scale 47 on top of the casing 10 which scale may be calibrated in terms of speed. The time marking device is not necessary if the length of tape fed out of the casing 10 in a given time is measured. In testing a taximeter the length of tape fed out during one fare stage will show whether the taximeter is correct. In the construction shown in Figs. 4 and 6 the worm 21 driven through the clutch 42 rotates a roller 48 driving an endless band 49 of graph paper passing over rollers 50 and treated so as to be marked by a metal point 68 formed on a U-shaped carriage 55 carrying a member 58 having wire bristles 60 spring-pressed into engagement with a threaded member 53 rotated by clockwork 54. The wire bristles 60 are held out of engagement with member 53 by a catch 61 actuated by the electromagnet 64 in series with a battery and with a switch within the clutch 42 to allow engagement of bristles 60 and threaded member 53 and cause carriage 55 and marking point 68 to be moved over graph paper 49, the carriage having a lateral extension 56 sliding freely upon a guide bar 57. A manual switch may be inserted in the circuit so that the carriage 55 can be freed at any desired instant subsequent to the engagement of the clutch 42. Specification 491,203 is referred to.

Title: Improvements in and relating to the production of artificial filaments, threads, fibres, bands and the like
Inventor: ROBERT LOUIS WORMELL LEONARD E
IPC: D01F1/10
Filed: 1953-03-05
Abstract: The process of the parent Specification (according to which freshly extruded protein threads are hardened and then treated with methyl alcohol or ethyl alcohol and an esterification catalyst) is modified in that the esterification is carried out by passing the threads continuously through a bath comprising methyl alcohol or ethyl alcohol and the esterification catalyst, pressing them to remove excess liquid and then passing the impregnated threads in convolutions into a J-box in which they are accumulated and stored while esterification is effected.  On withdrawal from the J-box the threads may be passed direct to the further hardening bath or the insolubilizing treatment described in the parent Specification.  It is advantageous to support the convolutions of threads in the J-box on a conveyer belt moving continuously or intermittently through the box, and this belt may be a continuous loop of fabric of polythene threads which is suspended in the J-box, looped round guide rollers outside the box and moved at intervals by means of external nip rollers.  In an example a continuous tow of hardened lactic casein threads is impregnated with an esterification liquor containing 450 grams of sulphuric acid, 500 grams of methyl alcohol and 250 grams of water per litre, passed through squeeze rollers and into a J-box in which is looped a polythene fabric endless belt.  The fabric is moved forwards intermittently and the tow is removed continuously after 2 hours' storage in the J-box at 25 DEG  C.  Specifications 774/08, [Class 15], and 201,864, [Class 15(i)], are referred to.
Patent GB-624304-A (GB)
Title: Improvements in or relating to the production of magnesium base alloys
IPC: C22C1/02
Filed: 1945-03-12
Abstract: A process for the production of magnesium base alloys containing zirconium comprises producing a molten mixture or compound salt containing zirconium chloride or bromide and one or more chlorides of sodium and potassium to form at least some proportion of a double salt, forming this mixture or compound salt into lumps which are broken into pieces of convenient size or forming the mixture or compound salt into suitable small pieces, p  bringing such pieces into contact with molten magnesium or a molten magnesium base alloy and agitating the melt to effect solution of the zirconium in the magnesium.  The mixture may include one or more halides not reducible by magnesium and/or one or more reducible halides of a permissible alloying element, i.e. of an element which does not form high melting point compounds with zirconium, e.g. zinc or cadmium.  This mixture may have a melting point below 300 DEG C.  When no alkaline earth metal chlorides are present the mixture may contain up to 50 per cent of zirconium fluoride.  The mixture may be made by adding a solid mixture of zirconium chloride and potassium and/or sodium chloride to a molten pool of a mixture of halide salts which are inert to magnesium and has a low melting temperature or range.  The mixture may contain at least 30 per cent zirconium chloride, at least 25 per cent zirconium fluoride and at least 10 per cent of another halide not reducible by magnesium.  Specific mixtures referred to contain: (a) approximately 75 per cent zirconium chloride and 25 per cent sodium chloride; (b) 45 per cent zirconium chloride, 35 per cent zirconium fluoride, 20 per cent sodium chloride.  Specifications 511,137, 511,482, 533,264 and 26438/39 (as open to inspection under Sect. 91) are referred to.

The adhesive surface may be produced by the application of rubber, celluloid and cellulose varnishes of all types, synthetic and natural resins, linseed oil and the like compounds, or glues; or by treating the surface of the thread, e.g. by solvents.  The coating materials used are cork dust, paper, comminuted cotton, paper, fibre, asbestos insulating materials, pulverized rubber, or mixtures thereof.  The coating materials may be applied while twisting or turning the thread about its longitudinal axis, or subjecting it to tension.  A thread may be treated throughout the whole of its length, or only in sections, and the coating may be such as to provide a multi-coloured effect.
Patent GB-938644-A (GB)
Title: Vapour phase nitration of cyclohexane
IPC: C07C205/05
Filed: 1962-02-16
Abstract: Mononitrocyclohexane is prepared by passing cyclohexane and nitric acid or nitrogen dioxide in the vapour phase through a reaction zone at 250-375 DEG C. for a period of at least 10 seconds, preferably 10-150 seconds, the proportion of cyclohexane being 4-10 mols, per mol. of nitric acid (calculated as HNO3) or 1-5 mols. per mol. of nitrogen dioxide (calculated as NO2). The cyclohexane and the nitrating agent are preferably mixed in the vapour phase, e.g. at 120-180 DEG C., before they are passed to the reaction zone.  The reaction mixture may also contain 0.5-1 mol. of nitric oxide, which may be added to the nitrating agent or to the reaction mixture at any stage before the nitrogen dioxide undergoes appreciable dissociation. The products may be condensed and cyclohexane may be separated therefrom by fractional distillation and returned to the process. The residue may be treated for the recovery of nitrocyclohexane by fractional distillation or conversion to the ammonium salt.  The uncondensible portion of the products may be oxidized, e.g. with hydrogen peroxide, to form nitric acid.  Alternatively, the process may be effected in stages, e.g. four stages, with addition of fresh nitrating agent between the stages.  In this case the proportion of nitrating agent added between the stages may be 0.8-1.2 mols, based on the proportion of nitrating agent added at the first stage, so that the proportion of cyclohexane to nitrating agent may fall below that prescribed for the first stage.  Nitric oxide may be added as the nitration agent added between the stages.  Examples are given.
