Patent GB-526927-A (GB)
Title: Process for the production of 4, 4-dihydroxy-ª‡, ª‰-diethyl-stilbene
IPC: C07C37/055
Filed: 1939-03-29
Abstract: 526,927. Stilbene derivatives. RICHTER GEDEON VEGYESZETI GYAR R. T. March 29, 1939, No. 9856. Convention date, March 30, 1938. [Class 2 (iii)] 4 - 4<SP>1</SP> - Dihydroxy - α - # - diethyl - stilbene is prepared from p-methoxy-propiophenone by converting it into the hydrazone, oxidizing this to the diazo compound, converting the diazo compound by the action of sulphur dioxide into 1:1<SP>1</SP> - di - (p methoxy - phenyl) - 1:1<SP>1</SP> - diethyl - ethylene sulphone, converting this by heating or by standing into 4:4<SP>1</SP>-dimethosy-α-#-diethylstilbene and finally removing the methyl radicals by alkaline saponification. In an example p-methoxy-propiophenone is reacted with hydrazine hydrate in the presence of barium oxide on the water bath, to give p-methoxypropiophenone-hydrazone which is stirred with mercuric oxide in petrol ether solution. The pmethoxyphenylethyldiazomethane so obtained is treated with sulphur dioxide to give a crystalline mass of 1:1-(dimethoxyphenyl)-1:1-diethylethylene-sulphone, and di-p-methoxy-phenyldiethyl ketazine. This crystalline mass is heated to 200‹C., when sulphur dioxide is evolved and 1:1-(di-p-methoxyphenyl)-1:1-diethylethylene is formed. This is hydrolyzed with alcoholic potassium hydroxide in an autoclave to give the required 4:4<SP>1</SP>-dihydroxy-α-#- diethyl-stilbene. The Specification as open to inspection under Sect. 91 includes also the production of symmetrical diaryl-dialkyl-ethylene compounds of the general formula where A stands for an alkyl radical, R for an aryl radical and n for the number of hydroxyl groups. No additional examples beyond those contained in the accepted Specification are included. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to waterproof sandpaper and backing therefor
Filed: 1953-04-10
Abstract: A heat-hardenable phenol-formaldehyde condensation product for use in making sandpaper is formed by reacting 1 part of a "technical" phenol containing 90 per cent phenol and 10 per cent cresylic acids with 1.2 parts of 37 per cent formaldehyde by re-fluxing for 1/2 hour in the presence of 5 to 7 per cent of barium hydroxide and 10 of di-propylene glycol (these percentages being on the weight of the phenol).  The reaction product was then dehydrated to 80 per cent solids and a viscosity of 10,000 centipoises at 25 DEG  C.

Abstract: 800,136. Blasting fuze cords; explosive compositions. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Nov. 26, 1956 [March 29, 1956], No. 9875/56. Classes 9(1) and 9(2) The explosive forming the core of a detonating fuze cord such as that described in Specification 747,878 is mixed with a cold water absorbent organic material which swells on wetting to form a plastic gel. The material may be a macromolecular polysaccharide or polysaccharide ether, which is preferably a waterdispersable sodium carboxymethyl cellulose. The amount of the organic material mixed with the explosive is preferably between 1 and 10 per cent. In an example 95 per cent by weight of pentaerythritol tetranitrate is mixed with 5 per cent of a water-swellable and water-soluble polysaccharide ether. This mixture is used to form a core which has a textile covering coated with bitumen and finally with polyethylene. Another core consists of 94.94 per cent pentaerythritol tertranitrate and 5.06 per cent sodium alginate.

Title: Improvements in or relating to reversing power transmission mechanism
IPC: B60K17/30
Filed: 1930-03-28
Abstract: 351,102. Reversing-gearing. HEATH, A. R. N., Rowans, Hartington Road, Chiswick, London, and BRIMLOW, J., D., Merlefield, Helensburgh, Dumbartonshire. March 28, 1930, No. 9909. [Class 80 (ii).] Reversing gear upon a vehicle comprises the combination with a gear wheel G<2> mounted on the upper end of the vertical shaft G of a horizontal shaft K carrying two driving gear wheels H, J meshing with the gear wheel G<2>, friction clutches for respectively connecting these gear wheels to the horizontal shaft, means for applying a brake directly or indirectly to the vertical shaft, and control mechanism for the clutches and brake such that when both clutches are disengaged the brake is automatically applied whereas the brake is automatically released when either clutch is engaged. In the construction shown, the shaft K is driven by chain gear L<2> from an engine L and carries a clutch plate K<2> slidably splined thereon. A clutch surface K<4> is carried by the rim of the clutch plate and is adapted to engage alternatively clutch surfaces J<3>, H<4> fixed on sleeves J<1>, H<1>, respectively secured to the bevel gear wheels J, H. Thus, when the clutch plate K<2> is moved to the right, (say) the clutch surface H<4> and gear wheel H are clutched to the shaft K and the vertical shaft G is driven in one direction; when the clutch plate is moved to the left the gear wheel J is clutched to the shaft K and the shaft G is driven in the reverse direction. A brake drum H<5> is formed on the disc H3 that carries the clutch surface H<4>, and this drum is normally engaged by a brake shoe M carried by an arm M<1> on a shaft M<2> having another arm M<3> pressed upwards by a spring (not shown) to apply the brake. The clutch plate K<2> is moved in either direction by means of a thrust housing N pivoted at N<2> to a lever O the long arm of which has a slotted head O<2> operated alternatively by two pedals Q<2> pivoted on a shaft P. One pedal carries a roller Q<3> below the shaft P and riding in a slot in the head O<2>, so that when this pedal is depressed the head is moved to the right and the clutch plate K<2> to the left to clutch the gear wheel J to the shaft K. The other pedal carries a roller R<4> above the shaft P, so that when this pedal is depressed the head O<2> is moved to the left and the clutch plate to the right to clutch the gear wheel H to the shaft K. At the same time, when either pedal is depressed the brake is automatically disengaged, each pedal being provided with a lug S<1> which rocks the brake shoe shaft M<2> by means of an arm M<5> thereon.

Title: Improvements in and relating to the regulation of electric distribution systems
IPC: H01J13/48
Filed: 1926-04-15
Abstract: 274,192. British Thomson-Houston Co., Ltd., and Knight, H. de B. April 15, 1926. Vapour apparatus.-A rectifier 3 supplying D.C. mains 2 from A.C. mains 7 in parallel with another source 1, such as a rotary or motor converter, generator or rectifier, is regulated by grid control so that it takes the load variation on the mains 2. The rectifier installation comprises a power transformer 4 connected to the anodes 12, and cathode 18 connected to the positive main, the negative main being connected to the midpoint of the transformer. The grids 11 are supplied through a transformer 14 fed by a phase shifting device from the mains 7, the mid-point of the transformer 14 being connected through a biasing resistance 19 to the cathode 18. Assuming the D.C. load increases, the source 1 tends to take more than its normal load, thereby increasing the voltage drop across a shunt 23, and the negative bias on a thermionic valve 22. The anode current of this valve decreases, and at this current passes through the resistance 19, the negative bias on the grids 11 is decreased, and the rectifier 3 opens earlier than normally and thereby takes the increase of load. A reverse action occurs upon decrease of load. Two or more valves may be used in place of the single valve 22 so to obtain sensitive regulation.
