Patent GB-484246-A (GB)
Title: Improvements relating to lifts
IPC: B66B7/06
Filed: 1937-03-03
Abstract: 484,246. Safety-suspension apparatus for lifts. FLOHR AKT.-GES., C. March 3, 1937, No. 6268. Convention date, March 3, 1936. [Class 78 (iii)] An auxiliary unloaded rope or ropes extends between a lift cage and its counterweight or between one cage and its counterbalancing cage, and is arranged to take up the load of the cage and weight and support them in the event of breakage or undue stretching of the main winding rope, while at the same time the release in the tension of the winding rope due to either cause actuates electric control mechanism to stop the driving-gear. Fig. 1 shows one central auxiliary rope 5 passing from the cage to the counterweight 4 between the pair of winding-ropes 2. Each. rope passes over a, separate driving-pulley 3, the centre one of which is more deeply-grooved than the others to secure an extra bite for the rope 5 when in action. Fig. 3 shows one method of connecting the ends of the ropes to the cage or the weight. The weight of the cage compresses the springs 9 between the ends of the screwed adjustment members 11 and the couplings 7 on the ropes. The central member 12 is adjusted by unscrewing it, so that the rope 5 is just kept taut without bearing any of the load of the cage. When the ropes 2 break or become unduly stretched the load is wholly or partly transferred to the rope 5 thus relieving the ropes 2 and allowing the springs 9 to expand. This releases spring members 13 from the ends of caps 11 and they are pressed upwards to make contacts inside the boxes 14 and stop the motor. The ropes 5 may be passed over separate compartments of the main winding drum where drums are used, or may be passed over separate loose or fast pulleys on the winding drum shaft. Fig. 5 shows a modification in which two auxiliary ropes are wound oppositely on the centre compartment 16a, of the winding-drum, one, 5a, passing to the cage and the other, 5b, passing to the other cage or the counterweight.

Filed: 1929-02-27
Abstract: 322,963. Stinson, O. Feb. 27, 1929. Urethrotomes and like instruments.-An instrument for use in operating upon animal's teats comprises a central part or member a having a pointed end b, an incision guide d, and a guard f, g. The guard determines the depth to which the member is inserted in the teat and so controls the depth of the incision which is made by a blade inserted in the guide and drawn across the end of the teat. If the incision is not sufficiently deep the device is withdrawn, turned through 90‹, and then reinserted; the guards then enter the incision previously made and the central member can consequently enter the teat to a greater extent and a deeper cut then be made. A safety-razor blade may be used to make the incision. The guard may be in the form of an arm g and an eyelet f, or two arms or two eyelets may be used. The slot d may be directed diagonally to give a proper incision in a deformed teat end; or the slot may be located parallel to, but spaced away from, the axis of the central part.

Title: Improvements in or relating to dyestuff intermediates
IPC: C09B35/08
Filed: 1943-04-21
Abstract: Dyestuff intermediates, consisting of mixtures of isomeric diaminodiphenyls, are manufactured by the reduction of mixtures of isomeric dinitrodiphenyls under acid conditions.  The starting material may be a mixture of 2 : 21-and 2 : 41-dinitrophenyls, such as that obtained by nitration of o-nitrodiphenyl, or the mixture, mainly of 2 : 21-, 2 : 41- and 4 : 41-dinitrodiphenyls, obtained by nitration of diphenyl.  In the latter case, the 4 : 41-diaminodiphenyl may be separated from the product, e.g. by converting it to a mixture of isomeric hydrochlorides, dissolving this in warm water, and adding 40 per cent sulphuric acid to precipitate the 4 : 41-isomer as sulphate.  In examples: (1) o-nitrodiphenyl is nitrated by means of a mixture of nitric and sulphuric acids, and the product, with or without purification, is reduced with iron powder and dilute hydrochloric acid; (2) diphenyl is nitrated by means of a mixture of fuming nitric and concentrated sulphuric acids, and the partially purified product is reduced with iron dust and hydrochloric acid. Specification 600,739, [Group IV (c)], is referred to.  The Specification as open to inspection under Sect. 91 comprises also the manufacture of disazo dyestuffs and pigments by the process of Specification 600,739.

Abstract: 1,138,333. Selective signalling. DAVY & UNITED INSTRUMENTS Ltd. 25 Feb., 1966 [16 Feb., 1965], No. 6579/65. Heading G4H. [Also in Divisions G1 and H1] The position of the cross-head of a forging press is measured by securing to it a ring 16 of magnetic material which moves relative to four parallel conductors A ... D, two of which form an A.C. energized primary loop, the other two a secondary loop in which signals indicative of the position of the ring 16 are induced by interactions of the magnetic ring 16 and a fixed magnetic core. In one embodiment the core comprises a series of slugs 15 so that the alternating current induced in the secondary loop is a maximum when the ring 16 is opposite a slug. By arranging alternate slugs at right angles, the phase of the output signal is reversed at consecutive slug positions. The signal maxima are counted by a pulse counter 14. To provide an indication of the direction of movement, two similar measuring systems may be provided, the outputs being asymmetrically out of phase. In another modification, Figs. 4 and 5 (not shown) two secondary loops are associated with a single primary and two sets of slugs are used in the core. In another embodiment, Fig. 8 (not shown) two primaries are linked with four secondaries by curved slugs. In another embodiment, Fig. 7 (not shown) the slugs are replaced by a continuous cruciform core, one cross arm tapering from top to bottom, the other from bottom to top. Then the e.m.f. induced in the secondary loop varies from a maximum in phase with the primary A.C. to nil, to a maximum out of phase.
