Title: Process of purifying aqueous liquids, particularly waste water from factories
IPC: C07C37/82
Filed: 1930-05-01
Abstract: The process of the parent Specification according to which aqueous liquids, particularly waste waters from coking plant or from cellulose or other factories, are treated with an absorbent, from which the absorbed constituents, for example phenols, are subsequently extracted by means of a solvent, retained solvent being finally driven off as by means of steam, is carried out so that access of air or other gases to the adsorbent is prevented, as far as possible, during the adsorption and extraction stages and particularly during the transition from one stage to another. When the aqueous liquid is passed upward through the adsorbent, the liquid in the treatment vessel at the termination of a treatment period is covered with a layer of the solvent and the solvent follows the liquid downward as it is withdrawn from below. The adsorption and extraction may be effected at raised temperatures, for example 40 DEG to 80 DEG  C., and one of these temperatures may be higher than another.ALSO:The process of the parent Specification according to which aqueous liquids, particularly waste waters from coking plant or from cellulose or other factories, are treated with an adsorbent, from which the adsorbed constituents, for example, phenols, are subsequently extracted by means of a solvent, retained solvent being finally driven off as by means of steam, is carried out so that access of air or other gases to the adsorbent is prevented, as far as possible, during the adsorption and extraction stages and particularly during the transition from one stage to another.

Patent GB-484361-A (GB)
Title: Improvements in or relating to devices responsive to radiant energy, particularly for steering craft
IPC: G01S1/02
Filed: 1937-05-19
Abstract: 484,361. Electric signalling systems. BRITISH THOMSON-HOUSTON CO., Ltd. May 19, 1937, No. 13973. Convention date, May 20, 1936. [Class 40 (i)] [Also in Groups XL and XXXV] Relates to devices responsive to radiant energy, particularly for automatically steering craft. According to the invention, there are employed in combination means including a pair of similar photo-electric cells or the like, 1, 2 for producing an alternating current whose positive and negative half-cycles are proportional to the relative amounts of energy received by the cells, an amplifier 14, 15, 16 for the current, and a non-linear resistor 23 through which the output of the amplifier is fed to a device 21 which is operative in one direction or the other in response to the polarity of the current supplied thereto. In the arrangement shown, an oscillation generator 3 supplies A.C. through a transformer 7 to the cells 1, 2, which are reversely connected in parallel with each other as shown, and are in circuit with a transformer 8 connected to the amplifier. If radiation falls unequally on the cells, the wave form of the A.C. passed through the transformer 8 is unsymmetrical, Fig. 2, the positive half-cycles or the negative half-cycles being the greater according to the one or the other of the cells 1, 2, receives the greater amount of radiation. This discrimination is indicated by the device 21, which as shown is of the kind having a pointer which is deflected to either side of zero in accordance with the direction of current flowing through it. The non-linear resistor 23, which is connected between the output transformer 20 and the indicator 21 is made of a material such as is described in Specification 292,110. [Class 37], which has the property of producing from an asymmetrical alternating current applied to it a direct current having a polarity dependent on the predomination of the positive or negative halfcycles. Thus the direction of the D.C. supplied to the indicator 21 depends on which cell 1 or 2 is receiving the greater amount of energy. In a modification, Fig. 3 (not shown), the apparatus is to be responsive to intermittent radiation, e.g. to light from a neon lamp fed with A.C. In this case, the oscillator 3 is dispensed with, and the cells are connected to a source of D.C. Specification 371,824 also is referred to. Reference has been directed by the Comptroller to Specification 441,194.

Abstract: 1,109,033. Gripper-shuttle looms. A. E. MOESSINGER. 1 April, 1966 [28 May, 1965], No. 14503/66. Heading: DIE. A gripper shuttle loom, wherein a continuously moving shuttle 21 is picked by a constantly rotating wheel 26 and band 28 through a shed 23 and is returned along a guide 25 by a second wheel 32 and band 34, has means to cyclically vary the rotational speed of the second wheel 32 so that, irrespective of the moment in a cycle at which a shuttle arrives at the wheel 32 it is returned to the wheel 26 at the correct moment in that cycle for picking. The variation in speed of the wheel 32 may be obtained by using elliptical gears or by angularly moving a planet wheel between a constantly rotating sunwheel and an internal gear ring driving the wheel 32. The wheel 26 may also have its cyclical speed varied if it is desired to utilise two shuttles and superimposed sheds and, in place of the bands 28, 34, a magnetic wheel may be used.

Title: Improvements in or relating to the production of play balls
Filed: 1933-05-19
Abstract: In a method of producing tennis and other play balls predetermined quantities of aqueous emulsions or dispersions of rubber, guttapercha, balata or similar vegetable resins are introduced into hollow spherical moulds, the moulds are closed and subjected to rotation about a variable axis, and the emulsions or dispersions are coagulated by subjecting them to temperatures below 0 DEG  C.  For example, a compounded latex containing rubber (100 parts by weight), sulphur (2 parts), zinc oxide (1 part), zinc diethyldithiocarbamate (1 part), mineral oil (5 parts) with a small proportion of casein, is placed in a mould and rolled for 40 minutes in a freezing solution at 14 DEG  F.  After warming to room temperature the ball is removed, dried and vulcanized in a mould for one hour in boiling water.  The rolling of the mould may be effected by placing the mould on two cylindrical rollers revolving in the same direction and moving axially in opposite directions. To inflate the ball a capsule of paraffin wax containing a gas-generating composition may be floated on the dispersion within the mould; alternatively, pressure gas may be introduced into the mould through a valve before solidification of the dispersion; or an inflating plug may be retained within the mould by a fine wire to form an integral part of the ball, the inflation being effected after moulding by means of a hypodermic needle. When an inflating plug is used, a fluid mixture of gelatine and glycerine may be introduced into the ball to form a gas-retaining lining.  For accelerating the coagulation of the dispersions at low temperatures sodium or potassium silicofluoride, calcium chloride, calcium sulphate, magnesium sulphate or zinc sulphate may be used. Specifications 219,635 and 290,313, [both in Class 70], are referred to.
