Title: An improved appliance for rolling mills
IPC: B21B39/04
Filed: 1933-12-12
Abstract: 428,244. Rolling. MATHIAS, H. T., 5, Old Mill, Gurnos, Ystalyfera, Swansea Valley. Dec. 12, 1933, No. 34896. [Class 83 (iv)] To raise a plate delivered from the rolls into position to receive it back over the top or to discharge it, the plate moving towards the receiving frame P Q trips a lever A which frees the crossbar X of a pair of cams C so that they rotate downwards so putting the mutilated gear wheel F in gear with a constantly rotated gear E so that the cams C are lifted up on the right-hand side and bear against J K and so raise the plate-receiving top P Q, attached thereto. Continued rotation causes the cross-piece X to engage the hooked end of S which tilts the top P Q about its pivot O, so that the plate if not already pulled back over the rolls, slides off down to the right.

Title: Improvements in or relating to luminous display devices
IPC: H05B41/44
Filed: 1935-12-30
Abstract: 459,813. Supply systems for discharge lamps. PACKARD PROPERTIES, Inc., 225, West 57th Street, New York, U.S.A.- (Assignees of Foerste, W.) Dec. 30, 1935, No. 35963. Convention date, Jan. 4. [Class 38 (iv)] [See also Group XVIII] Two or more super-posed electric discharge tubes 10, 11 of similar shape are illuminated alternately to give a changing colour or intensity effect, and, when received at an angle, an aminated appearance. These effects may be produced by employing different gases in the tubes or by colouring the tubes themselves. The means for exciting the tubes alternately consists in giving each a different striking voltage, either by, employing different gas pressures or by having tubes of different cross-sectional area. Electromagnets 19, 20 are in series with the tubes 11, 10 respectively in a high-tension circuit leading from a transformer secondary 13. Each magnet acts on an extremity of a pivoted armature 17. Excitation of the magnet 20, taking place simultaneously with illumination of the tube 10, tilts the armature 17 to close contacts 18 and to put the magnet 19 and tube 11 in parallel with the magnet 20 and tube 10. The tube 10 has a higher striking voltage than the tube 11, and is thus extinguished when both tubes are in circuit, the glowing tube 11 being seen through the tube 10. As soon as the magnet 19 is energized the contacts 18 are broken and the tube 11 extinguished and the tube 10 re-lit. The magnets may be protected against high self-inductance by bridging them by high resistances 21, 22. A plurality of transformers, magnets, and pivoted armatures may be provided, each controlling a section of tube. Synchronization of illumination of each section may be attained by giving all the transformers a common primary circuit, with one or both of the respective electromagnets of each set in series.
Patent GB-491640-A (GB)
Title: Improvements in or relating to process of regenerating pickling baths
IPC: C23G1/36
Filed: 1937-12-29
Abstract: Sulphuric acid baths used for pickling metals are regenerated by adding to the spent bath a fatty alcohol soluble in aqueous media, e.g. methyl and ethyl alcohol in order to precipitate the metal sulphates, e.g. those of copper or iron, <PICT:0491640/III/1> dissolved in the bath.  Preferably, the addition is made after cooling the bath to below 40 DEG  C. and the volume of alcohol added is about equal to the volume of the bath to be regenerated.  As shown, the hot spent solution collecting in a vat 1 is pumped into a separator 3 provided with a cooling coil and a stirrer.  When the temperature has fallen to 30 DEG  C., methyl alcohol is added from a measuring container 6.  When the salt precipitates, cooling and stirring are stopped.  The contents of the separator are passed into a centrifuge 7 which retains the sulphate crystals while the mother liquor flows to a tank 9.  Alternatively a preliminary decantation takes place in the separator the liquor passing directly to the tank 9 and the centrifuge being used only to separate the crystals from the remaining liquor which is also passed to the tank.  The liquor is pumped from the tank 9 via a tank 11 into a distillation tower 12. The alcohol is condensed in a condenser 13 and is returned to the container 6.  The residual sulphuric acid collects at 14 and is pumped to the initial vat 1 where it is replenished with water, and acid if necessary. Preferably the distillation is conducted so that a small amount of alcohol remains in the acid as this limits the action of the acid in the metals to be pickled.  The process is also applicable to the separation of sulphates from a mixture of sulphuric and hydrochloric acids.ALSO:The action of sulphuric acid, or a mixture of sulphuric and hydrochloric acid, on metals being pickled is limited by the presence of a small quantity of a fatty alcohol soluble in aqueous media, e.g. methyl or ethyl alcohol.

As described the felt is of organic, e.g. cellulosic, fibres preferably consisting of fibres derived from cottons, carpet waste, flocks, and cardboard container waste in proportions 5:2:2:1 by weight. Preferably the resin is produced from a mixture of unsaturated hydrocarbon monomers having a molecular weight of 87 to 93, e.g. "Piccopale 100SF" (R.T.M.).  The felt is preferably 10 to 140 mils thick and contains 8 to 30% by weight of resin.  The felt may be indented on one or both faces and/or perforated particularly near one or more of its edges.  Two or more plies of felt may be adhered to each other by means of a sodium silicate solution.  In the example given felt is loosely laid with a 2 inch overlap on a concrete substrate and hot asphalt is poured on to a depth of approximately 5/8 inch.
Patent GB-344420-A (GB)
Title: Improvements in the manufacture of organic substitution derivatives of cellulose
IPC: C08B11/14
Filed: 1929-11-28
Abstract: Amino aralkyl ethers of cellulose are produced by reacting on cellulosic material in the presence of a base such as caustic alkali, with an amino aralkylating agent, or alternatively, with a nitro aralkylating agent and subsequently reducing the product. The etherification may be carried out in presence of sufficient caustic alkali to form a concentrated solution with any water present, and is preferably present in a proportion greater than 3 times the weight of the water.  Substances adapted to bind water by chemical reaction, such as are described in Specification 187,639, [Class 2 (ii), Cellulose &c.], and also catalysts, e.g. copper powder or copper salts or hydroxides may be added.  As initial materials there may be used cellulose or its near conversion products such as regenerated cellulose, wood pulps, or cellulose derivatives containing free hydroxy groups; the etherifying agents specified are 2-chlormethylbenzylamine; ortho-g -chlorpropylaniline; ortho-b -chlorpropylaniline; 3-acetaminobenzyl chloride; 4-acetaminobenzyl chloride; o-, m-, or p-nitrobenzyl chloride; 2, 4, dinitrobenzyl chloride; 4 nitro-b -chlorethylbenzene; 2 nitro-1, 4 dichlormethylbenzene. The reduction of the nitro aralkyl ether to the corresponding amino ether may be effected by treating the ether in solution of suspension in glacial acetic acid with iron powder, or by treating the ether with hydrosulphites in aqueous or aqueous-alcoholic solution.  The cellulose ethers containing primary or secondary amino groups may be reacted with alkylating, aralkylating, arylating, or acylating agents; furthermore, where the amino ethers contain free hydroxy groups, these groups may be alkylated, aralkylated, or acylated.  According to examples, (1) cotton or purified wood pulp is etherified in two stages by means of 2 chlormethylbenzylamine; (2) the etherifying agent of (1) is replaced by 3 acetaminobenzylchloride; (3) mercerized cotton yarn is etherified in benzene solution by means of 3 acetaminobenzyl chloride; (4) cotton or purified wood pulp is treated in the presence of caustic soda with p-nitrobenzyl chloride, and the p-nitrobenzyl cellulose is reduced.  The products may be formed into filaments, threads, ribbons, and the like, having an affinity for acid wool dyestuffs.  Specification 164,375, [Class 2 (ii), Cellulose &c.], also is referred to.
