Filed: 1935-12-02
Abstract: 471,502. Waterproofing ground. TRAVAUX SOUTERRAINS. Dec. 2, 1935, No. 33402. Void. Convention date, June 22. [Class 140] [Also in Group XXI] Coherent strata, such as sandstone through which bituminous or like substances in suspension would not percolate, are rendered waterproof by driving into the ground injection tubes 2 so that their lower ends are situated in a predetermined plane and spaced apart a distance such that when liquids such as washing water or bituminous suspensions are forced under pressure into the tubes fissures develop between the ends of the tubes and the obturating suspension may be forced through the fissures to provide a substantially continuous waterproof layer 3. In triassic or tertiary sandstone the pressure used is 20 kg. per sq. cm., the minimum depth of the layer 2 metres and the distance apart of the tubes 4 to 5 metres. Washing water is first injected, then an alkaline solution such as sodium carbonate, then the bitumen emulsion with or without an electrolyte. The operations are repeated successively in the various boreholes.

Abstract: 795,074. Electric digital-data-storage apparatus. SIEMENS EDISON SWAN, Ltd., [formerly SIEMENS BROS. & CO., Ltd.]. Nov. 23, 1956 [Nov. 24, 1955], No. 33738/55. Class 106 (1). A magnetic information storage arrangement comprises a continuously running magnetic storage device from one track of which information is read and transferred for temporary storage in another track of the device during one period and during a' subsequent period is transferred back to the position from which it was read, a utilization circuit being arranged to utilize and possibly modify the information during at least one transfer process. As shown in Fig. 1, a magnetic drum store has storage tracks T1, T2 associated with read/write heads H1, H2 having separate reading and writing coils c1, c2 linked with respective magnetic circuits each defining a gap g close to the associated track. The reading coils c1 of the two heads H1, H2 are connected through respective switching gates G2, G3 to the input side of a common reading amplifier RA, the output from which is fed to a utilization circuit UC. The utilization circuit feeds information to be re-stored on the drum to the writing coil c2 of one or other of the two heads via respective gates G1, G4 and respective writing amplifiers WA1, WA2. The pulse trains PI, P2, Fig. 4a, are. such that a P1 pulse is applied to the gates G1, G3 during oddnumbered revolutions of the drum, while a P2 pulse is applied to the gates G2, G4 during even-numbered revolutions of the drum. Thus, on each odd-numbered revolution, information is read from track T2, passed to the utilization circuit, and applied to the writing coil of head H1 to be stored in track T1. On even-numbered revolutions, the information stored in track T1 during the previous odd-numbered revolution is read, passed to the utilization circuit and applied to the writing coil c2 of head H2 to write the information back on to track T2 in its original position. With reference to the embodiment of Fig. 2 (not shown) there is described an arrangement whereby n successively utilized storage tracks share a common transfer track, there being a common utilisation circuit and common reading and writing amplifiers. Information from any .particular track is utilized only every 2n'th revolution of the drum. The embodiment of Fig. 3 (not shown) enables new information to be inserted at any instant into any one of a number of storage tracks. Moreover, in this embodiment the storage tracks share two transfer tracks used alternately. The stored information can thus be processed at twice the rate that it can with a single shared transfer track. Furthermore, the stored infortmation is utilized only during its transfer to one of the transfrer tracks and not during its return, thereby enabling a single utilization circuit to deal with all the stored information on all the storage tracks concerned. Practical circuits for the gating devices of the various embodiments are described.

Filed: 1928-11-17
Abstract: 322,082. Johnson, J. Y., (I.G. Farbenindustrie Akt.-Ges.). Nov. 17, 1928. Modifying chemical characters of metals.- All or part of the impurities which form volatile compounds with oxygen are removed from metal powders by subjecting the powder to oxidation to such an extent only as to supply sufficient oxygen to produce volatile oxygen compounds of the impurities to be removed, and then volatalizing the impurities by heating. The oxidizing agent may be oxygen, air, carbon dioxide, water, &c., and the volatilization may be effected at about 500 C. in an inert or reducing gas. The manufacture of the metal powder, the oxidation, and in some cases also the volatilization, may be carried out in one operation; for example, an oxidizing gas may be introduced into a vessel in which iron carbonyl is being decomposed, the oxidized iron powder obtained being then further heated or allowed to fall through a heated tube or into a bath of molten iron. The volatilization may be carried out at such a temperature, with the simultaneous or subsequent application of pressure if desired, that the powder sinters to form porous or non-porous articles.

The arrangement may comprise a perforated or magnetic tape on which the identity of, and the message for, the wanted subscriber are recorded serially on a same track or in parallel on a number of tracks. The calling subscriber is apprised of the busy condition of the exchange or wanted subscriber by the reversion of a special signal and he may signify his requirement of the storage arrangement by operating a special key, sending a special teleprinter code or simply by taking no action at all whereupon the exchange seizes a free tape, transfers thereto, from the usual register, the identity or part identity of the wanted subscriber and thereafter records the rest of the identity (if any) and the message when the caller transmits these. When the called party becomes free or when the congestion in the exchange reduces the stored identity is automatically read-out and a path to the called subscriber is set up whereafter the message is read out. If further congestion is encountered, a new store, associated with that part of the network which has been reached, is seized and the contents of the first store then transferred thereto. This procedure is repeated if necessary until the message has been properly delivered. The subscriber may be provided with a dial or a push-button keysender. The exchange may utilize a crosspoint (Fig. 1, not shown), or a rotary (Fig. 2, not shown), switching network.

Filed: 1929-11-11
Abstract: 338,719. Standard Oil Development Co., (Assignees of Lewis, W. K.). Nov. 12, 1928, [Convention date]. Gases, separating by absorption. - Gaseous mixtures, more especially of hydrogen and hydrocarbons, are separated into two fractions by contacting the mixture under high pressure, preferably above 20 atmospheres, with a solid material having a preferential adsorption for one component under pressure, such as activated charcoal, bone charcoal &c. The unadsorbed gas is withdrawn, and the adsorbed gas is then removed by reduction of pressure, and heat if necessary, and separately collected. In an apparatus described, the gas mixture enters at 1, is compressed and cooled and enters a pipe 4, leading through valves 8, 9 to adsorption chambers 10, 11, which may be fitted with heating or cooling coils 12, and are used alternately. When using chamber 10, the gas passes out-through a valve 18 and pipe 17, and is richer in hydrogen than the original gas. On saturation of the adsorbent material, the incoming gas is diverted through chamber 11. Valves 35 and 28 are opened, and hydrocarbon gas from cylinder 30 is admitted to chamber 10 in order to flush it and to maintain the pressure, the outflowing gas being conducted back by pipe 27 for retreatment. This outflowing gas passes through a gas balance B until no hydrogen remains in the mixture, when the above valves are closed, and the pressure slowly released by valve 25. A part of the outflowing gas is used to recharge cylinder 30 and the remainder passes out through a pipe 20 to storage. More than two absorption chambers may be used in series.
