Title: Improvements relating to the suspension of electrodes in electric furnaces
IPC: C25C3/12
Filed: 1953-02-23
Abstract: 724,423. Electric furnaces with self-baking electrodes. ELEKTROKEMISK AKTIESELSKAB. Feb. 23, 1953 [Feb. 26, 1952], No. 5007/53. Class 39 (3). An electric furnace for the electrolytic production of aluminium with a continuous self-baking electrode 2 having a permanent casing 4 has means for raising and lowering the electrode together with the casing relatively to the furnace, and independently 'operable means for raising and lowering the casing 4 relatively to the electrode during furnace operation. The electrode 2 is supported by vertical contact rods 3 on a horizontal current supply beam 7, from which the casing 4 is supported by a pair of screw jacks 10 operated preferably by motors 12. The beam 7 is supported on jacks 8 operated by electric motors. Thus the electrode 2 and casing 4 are lowered together by the jacks 8 when the furnace is tapped, and between tappings the casing 4 is raised relatively to the electrode so as to keep the height of the casing above the surface of the molten furnace bath constant. The motors operating the jacks 8 and screw jacks 10 may be synchronized so that the electrode 2 can be vertically adjusted while keeping the casing 4 stationary relatively to the furnace pot. Gases developed are collected in gas duct 6 surrounding the electrode and are led off and burnt as in Specifications 608,656 and 659,509 which are referred to.

Patent GB-297278-A (GB)
Title: Improvements in and relating to thermionic voltage regulating devices
IPC: G05F1/52
Filed: 1928-02-17
Abstract: 297,278. Moss, E. B., and Cambridge Instrument Co., Ltd. Feb. 17, 1928. Regulation, automatic. - The fluctuating voltage existing between conductors 3, 4, either connected to a D.C. supply or to an A.C. supply through a rectifier 6, is regulated by a thermionic valve V and an impedance R so that the voltage across the output conductors 7, 8 is either constant or varies in a predetermined manner with the variations of the supply. If the voltage of the supply increases, the temperature of the filament of the valve V increases and hence also its space current, thus causing a greater voltage drop in the impedance R, which, if chosen suitably, will exactly compensate the rise in the supply voltage. If apparatus, such as valve 12 having its filament supplied from the fluctuating source, is to be supplied with anode current by the devices V, R, then the impedance R is chosen so that the voltage across the output 7, 8 fluctuates to such an extent as to keep the anode current of the valve 12 constant. Further, in the case of the grid of the valve 12 being connected to a photo electric cell 13 which is illuminated by a lamp run from the same mains, complete compensation for fluctuation of the voltage of mains can be obtained by suitably choosing the value of the impedance. Specification 279,214, [Class 38 (ii), Electric currents, Converting &c.], is referred to.

IPC: C09B3/48
Filed: 1928-02-18
Abstract: 285,502. I. G. Farbenindustrie Akt.- Ges. Feb. 18, 1927, [Convention date]. Samples furnished. Anthraquinone vat dyes dyeing cotton from blue to violet or black shades are obtained by heating polyhalogenpyranthrones or their derivatives with such quantities of nitrogen-containing compounds in which at least one reactive hydrogen atom is connected to the nitrogen atom, that several or all of the halogen atoms are substituted by nitrogenous radicles. The reaction is best carried out in dissolving or suspending media of high boiling-point, e.g. nitrobenzene or naphthalene, and catalysts, e.g. copper or its salts, or acid-binding agents or both may be present. The products are essentially different from those in which only one halogen atom is substituted. In examples, tribrompyranthrone is heated with alphaaminoanthraquinone, tetrabrompyranthrone with 1-amino-4-methoxyanthraquinone, and dibrompyranthrone with 4-amino-1 : 1<1>-dianthrimide; in each case in the presence of nitrobenzene, sodium acetate and copper carbonate. Specification 289,188 is referred to. Di-, tri-, and tetrabrompyranthrones are obtained by acting on pyranthrone in chlorsulphonic acid with the calculated amount of bromine.

Title: Improvements in or relating to directional radio transmitting and receiving systems
IPC: G01S3/14
Filed: 1939-02-16
Abstract: 526,417. Directive wireless systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and FALLOON, S. W. H. W. Feb. 16, 1939. No. 5187. [Class 40 (v)] A directive aerial system, of the kind in which two or more pairs of "crossed" frames are spaced apart and rotated about the centre of the connecting axis, is arranged to avoid the production of " false zeros " due to night error. As shown in Fig. 2, two crossed frames a, b, and a<SP>1</SP>, b<SP>1</SP>, are mounted on a common axis d rotated around r, and are fed (for transmission) from a common carrier-source (not shown) having two outputs capable of independent modulation. The frames a and a<SP>1</SP> are fed with one half-wave of the modulated output, and the frames b, b<SP>1</SP> with the other half-wave. The arrangement ensures that only one pair of frames can give a "false zero," and this appears only as a change in tone. In Fig. 4, for instance, A represents the signal normally heard, which becomes zero only at the true minimum line (at right-angles to the connecting axis d) whilst B represents the lowered tone heard at a " false zero." The arrangement of Fig. 2 gives the desired result for the reflected space-wave, whilst that shown in Fig. 5 is used for the ground wave. In the latter case, the frames a, a<SP>1</SP> are mounted at right-angles to, and the frames b, b<SP>1</SP> parallel with the connecting axis d. The modulated frequency may be squaretopped instead of sinusoidal.

Title: Improved process for preserving food products
IPC: A23B7/148
Filed: 1929-02-16
Abstract: 332,209. Milani, E. Feb. 16, 1929. Preserving fruit and vegetables.-Fresh, ripe fruit and vegetables are stored for a limited period against deterioration by hermetically sealing the product in the presence of an inert gas and then minutely venting the container prior to, or very soon after the product generates its own gas, and at about the time it begins to sweat, and permitting the said vent to remain open. The vented container is preferably stored at a relatively low temperature, as, for example, 30‹ to 35‹ F. The inert gas may be introduced into the container by burning a material within the container, or the container and contents may be subjected to a vacuum followed by the addition of carbon dioxide or other inert gas. By way of example, the period during which the container is kept sealed prior to venting in the case of strawberries is two days, apricots three days, and pears five days.
