Patent GB-584892-A (GB)
Title: An improved process and apparatus for the countercurrent contacting of liquids of different gravities
IPC: B01D11/04
Filed: 1945-02-02
Abstract: <PICT:0584892/III/1> <PICT:0584892/III/2> Countercurrent treatment of liquids of different gravities forming a disperse and a continuous phase is effected in a tower divided into sections by a series of horizontal plates, each plate being provided with one or more apertures for the passage of the continuous phase and with one or more troughs having a perforated base for the passage of the disperse phase.  If the lighter liquid moving up the tower 24 is to be dispersed through the heavier liquid moving down the tower, the troughs are inverted as shown in Fig. 1a.  Plate 20 in tower 10 is provided with an inverted trough 21 in which the lighter liquid collects and from which it is sprayed through the orifices at 26, 27 and dispersed in the form of droplets through the heavier liquid moving down the tower.  The spaces 24, 25 between the edges of the plate and the shell of the tower serve as passageways for the downward flow of heavier liquid.  Plate 30 has two inverted troughs 31, 32 perforated at 36, 37, for the collection and dispersion of the lighter liquid, and a central gap 35 permits downflow of the heavier liquid.  The tower contains a series of plates 20 alternating with plates 30.  In a modification, a multiplicity of inverted troughs may be used on each plate as shown in Fig. 3a. The troughs may extend longitudinally across the tower or take a circular form.  If the heavier liquid moving down the tower is to be dispersed then the troughs are not inverted.  Countercurrent liquid-liquid treatment according to the invention provides for intimacy of intercontacting without the formation of stable emulsions, and results in an improved plate efficiency.  An example is given in which butane containing acetone is passed up the tower, the dimensions of which are specified, and is dispersed through water passing down the tower, the acetone thereby being removed from the butane and washed out with the water.

Title: Wireless antenna arrangements
IPC: H01Q21/20
Filed: 1937-01-29
Abstract: 472,579. Aerials. LORENZ AKT.-GES., C. Jan. 29, 1937, No. 2729. Convention date, Feb. 6, 1936. [Class 40 (v)] Relates to aerial arrangements in which a central radiator is surrounded by a circle of reflectors in order to suppress the space-wave and to give a uniform field-distribution horizontally. According to the invention, the central radiator M, fed from a high-frequency source S, is connected by single-wire conductors E to the base of each of the reflectors A. Inductances C, either in combination with an arrester circuit or in series with condensers such as F, tune the lines E to half the working wavelength, and maintain the currents in the reflectors A in correct phase. A counterpoise of flat wires may extend parallel with the lines E.

Title: Improvements in and relating to water level alarms for motor car and like radiators
IPC: F01P11/18
Filed: 1925-01-30
Abstract: 246,314. Del Cozzo, J., and Goble, A. W. Jan. 30, 1925. Alarms, low-water.-A hollow casing 8 having an open-ended branch 9 communicating with the interior of a motor car &c. radiator 5 below the safety-level of the water is connected by a pipe 21, 23 having telescopic joints 22, 24, to a whistle 28 mounted on the instrument board 6, whereby steam passes to the whistle to warn the driver when the water has evaporated unduly. The casting 8 contains a ball float valve 13, Fig. 2, which is lifted against its seating while the water level is maintained, but drops against a stop-pin 16 when the level falls and allows steam to pass through the pipe 23 to sound the whistle. A second ball-valve 17 normally held closed by a spring 18 is mounted at the top of the casting 8, and is lifted by the steam pressure when the pipe 23 is obstructed for any reason, whereby a whistle 19 of a different tone may give an alarm. The whistle 28 has an opening 34, Fig. 3, for the escape of condensed steam, and is secured by bolts 29 to the instrument board.

Abstract: 402,618. Yarn supply. HEMPHILL CO., Central Falls, Rhode Island, U.S.A.- (Assignees of Lawson, R. H.; 55, Cooke Street, Pawtucket, Rhode Island, U.S.A.) Jan. 31, 1933, No. 2981. Convention date, March 22, 1932. [Class 74 (ii).] A device for governing yarn tensions, shown as applied to the knitting-machine of Specification 300,605, [Class 74 (ii), Knitting &c.], consists of means positioned operatively between the supply and the feed and acting to permit the yarn to pass freely to the knitting &c. elements as and when the source of supply is drawn on. Bobbins 6 are mounted on spindles 7 carried by a plate 8 forming part of a rotary unit. The yarns pass between sets of gears 11 .... 13, under a wire 17, through eyelets in spring take-up arms 19 and down to eyelets in a lap-stripe feeding disc 5. The arms 19 are mounted on a split ring held in position in its seat 22 by a screw 24. The points to which the tension springs 26 are attached can be varied as shown. In a modification the yarns, instead of passing between gear wheels, pass between clamping surfaces consisting of recesses 44 and co-operating pins 42 on tensioned arms 40. When tension is imposed on the yarns, the take-up arms 19 bear on the ends 48 of the arms 40 thus opening the clamps. In a further modification levers controlled similarly to the arms 40 engage or release the gear wheels 11.

The opposite end wall 13 slopes in the same direction. A groove 17, aligned with groove 16, extends from wall 13 towards the needle point. In a modification, Fig. 12, the end walls 12 and 13<1> slope in opposite directions and thereby each makes an acute angle with the needle surface at the same side as groove 16. A groove 17<1>, extending towards the point, does not break into wall 13<1>. In a further modification, Fig. 14, end walls 12<1>, 131 both slope rearwardly. Groove 16 breaks into wall 12<1>, and a pointwardly-extending groove is not provided.
