Filed: 1925-10-01
Abstract: 268,398. Flinn, H. V. Oct. 1, 1925. Aerials; directive signalling; receiving sets.- To facilitate reception from any given station, a frame aerial is combined with a map in such a way that the spindle of the frame coincides with its actual geographical location on the map. The frame is orientated for maximum reception from a known transmitting station, say Daventry, and when in this position a pointer is aligned with that station on the map and is then fixed by means of a set-screw. Any other station can then be found by rotating the frame aerial until the pointer indicates the map position of the desired transmitter. Fig. 3 shows a modified arrangement on which two separate pointers G, H are controlled by bevel gears C, D to give simultaneous indications, for instance on large and small scale maps. The maps may be transparent or opaque, and may be mounted separately on a toggle-joint support and moved into line with the pointers. According to the Provisional Specification, dials marked with the positions of various transmitting stations may be used in place of the maps. As shown in Fig. 7, the frame aerial A may be mounted separately and connected by belt gearing with the indicating pointer G.

Abstract: 744,022. Washing and drying machines. GENERAL ELECTRIC CO. Sept. 4, 1953 [Sept. 4, 1952], No. 24523/53. Class 138 (2). [Also in Groups XIII, XXIV and XXV] A clothes washing and/or drying machine having a .spin basket 3 driven by an electric motor is provided with a switch 19 having its normally open contacts included in the energizing circuit of the motor and moved to closed position when the cover 8 of the machine is closed so that the spin basket is driven only when the cover is closed, and means for locking the cover in its closed position comprising a locking lever 10 co-operating with a hook-like member 12 secured to the cover 8, electrical operating means energized when the motor circuit is closed for moving the lever 10 to engage the hook like member 12 to lock the cover in its closed position, and means to delay the return of the locking lever to its unlocking position when the motor circuit is interrupted and the electrical operating means thereby de-energized, the delay being such as to prevent unlocking of the cover until the spin basket stops or substantially stops rotating. In the example shown the lever 10 is pivoted in a flexible grommet 11 and is operated by a bimetallic strip 14 which is influenced by a heating winding 17 in the motor circuit. The heating capacity of the winding 17 is such that locking takes place within seconds of closing the motor circuit, but the cover is held locked until the strip 14 cools down, this being the time required for the basket to come to a stop. In another example (Fig. 4, not shown), the locking lever is operated by a solenoid against the action of a spring, return movement of the lever being retarded by an adjustable dashpot device.

Title: Improvements relating to the production of amines
Filed: 1937-09-09
Abstract: 501,927. Amines ; alcohols. KODAK, Ltd. Sept. 9, 1937, No. 24592. Convention date, Sept. 9, 1936. Addition to 501,763. Drawings to Specification. [Class 2 (iii)] Mixtures of aliphatic amines, an alcohol and water, with or without ammonia, obtained by the process described in the parent Specification, are worked up by removing ammonia, if present, by distillation, treating the mixture of amines, alcohol and water with an acid to convert the amines into salts, removing the alcohol from the amine salts by distillation, reconverting the amine salts to amines by the action of alkali and separating the primary amines from other amines by distillation. In an example, a mixture of butylamine, dibutylamine, butyl alcohol, ammonia and water is introduced into a feed tank, whence it passes into a distillation column from which a mixture of ammonia, butyl alcohol, butylamine and water distils and is passed to a series of condensers which return the components other than ammonia to the column, from the base of which the liquid freed from ammonia is pumped to a second column. Sulphuric acid, preferably dilute, is run into this column and converts the amines into their sulphates with evolution of heat, which, together with additional heat supplied by circulating steam, causes a butyl alcohol-water azeotrope to distil off. These vapours are condensed and the butyl alcohol and water are separated in a decanter or separator, the water being returned to the column. The mixture of butylamine and dibutylamine sulphates and water is fed at an intermediate point into a third column, where the amines are liberated from their salts by means of caustic alkali, e.g. caustic soda, the heat generated, supplemented if necessary by additional heat; causing butylamine to distil from the top of the column. An aqueous solution of dibutylamine and excess alkali is passed to the top of a fourth column, whence a dibutylamine-water azeotrope distils off and is condensed and separated, the dibutylamine being returned to the column, from the bottom of which it is finally recovered in an anhydrous condition. The process is also applicable to the treatment of mixtures of amylamines, amyl alcohol, water and ammonia, and to the production of other amines such as propylamine.
