Title: Improvements in or relating to carbon electrodes
IPC: C25B11/14
Filed: 1957-10-18
Abstract: The operating characteristics of carbon electrodes in an electrolytic cell are improved by impregnating the electrode with a polymerizable oil alone and subjecting the impregnated electrode to an oxidizing atmosphere at a superatmospheric pressure to effect polymerization of the oil in situ within the electrode.  The whole treatment may be carried out in a single container.  A graphite electrode, e.g. the anode of a chlorine-producing cell, is deaerated in a jacketed impregnator by a vacuum of 1-2 mm. Hg. and raw linseed oil is forced into the electrode under atmospheric pressure.  Impregnation is completed by application of superatmospheric pressure, e.g. 50-500 p.s.i.g., of inert gas, e.g. N2 or CO2, while heating by passing steam into the jacket at 150 p.s.i.g. for 10-30 mins. Pressure is released and oil drained off, and a portion of the oil is removed from the electrode by subjecting it to a number of exposures, e.g. 6-12, of high pressure (150 p.s.i.g.), steam, each followed by venting, to leave 8 wt. per cent or less oil content.  Steam is then passed over the surface of the electrode to strip off exuded oil. The electrode is finally heated by the steam jacket to 150-350 DEG F. in air at 3-10 atmos. for 1-8 hrs. The air may be vented and changed at 10-15 min. intervals. Oxygen, or other free oxygen-containing gas may be used.  A number of other polymerizable oils are exemplified.

Title: Improvements in carburetters for internal combustion engines
IPC: F02M69/00
Filed: 1919-12-30
Abstract: 164,403. Prentiss, A. M. Dec. 30, 1919. Spray carburettors.-The liquid fuel supply is subjected to a variable pressure greater than atmospheric so that the ratio by weight of fuel to air is kept constant. The apparatus is adjusted so that the flow of fuel in relation to air is correct at the highest speed, the deficiency at lower speeds being made up by increasing the pressure on the fuel as the speed diminishes. In the carburettor shown in Fig. 1, the supply of fuel to the float-chamber 3 is controlled by a plug valve 41 attached by an arm 40 to the float 39, and having a fuel passage 43 connected with a fuel tank 49 and an air passage 45 connected to the space above the fuel in the tank 49, this space being supplied with air under pressure by a pump 51 driven from the engine. The level of fuel in the float chamber 3 being maintained constant, the fuel passes to the mixing chamber 2 through apertures 30 leading to fuel nozzles 26 shown in detail in Fig. 6, the air passing through channels 45, 46, 23 to the annular space between the nozzles 26 and a tube 25. The air being discharged with the fuel through eccentric openings 28 in the caps 27 serves to atomize the fuel. Variable pressure on the fuel in the float chamber is obtained by a spring or weight-pressed piston 13 the space above which communicates by a port 8 with the induction pipe 8<11>, air being imprisoned between the piston and the surface of the fuel. The spring 11, the initial adjustment of which is effected by turning a cap 7 to the reading of an index 65 to suit the grade of fuel, is made of varying temper and as the suction increases with increase, of engine speed, the piston rises against the action of the spring and causes the pressure on the fuel to be gradually relieved in accordance with a law obtained from special curves described in the Specification. Ports 16 are uncovered by the piston to establish atmospheric pressure on the fuel at high speeds. By rotating the tubular mixing chamber 2 by handle 61 the fuel nozzles 26 are moved with respect to the ports 30 so as to bring them into action progressively, the air ports 20 at the lower part of the tube being at the same time moved with respect to fixed ports 21 to give the progressive amount of air to suit the fuel. The fuel spray may be adjusted by hand by turning a spindle 34 connected by a plate to levers 31 on the caps 27.

Filed: 1920-11-22
Abstract: 154,207. Espenschied, L. Nov. 21, 1919, [Convention date]. Track apparatus actuating signals on trains and for stopping trains.-Apparatus on a train for indicating by signals or for stopping the train is actuated by an electric wave reflected along conductors on the track from a train ahead. The train A sends out from a high-frequency generator G, either inductively or by direct contact with the rails or other track conductors -electric waves along the track rails T, which are reflected by the train A2 back to the sending train. The intensity of the reflected wave received by the train A1 depends upon the distance between the trains. The apparatus is designed to give different signals or brake application according to the intensity of the reflected wave. The apparatus indicated in Fig. 1 includes a balanced Wheatstone bridge circuit with a receiver R as the indicator, and the coil C, which makes inductive connexion with the track rails, as the variable arm and the network N is adjusted to give balance when the distance between the trains is such as to be safe. The arms a, b form the ratio arms. Several modifications are described; in one of these, currents of two frequencies are employed in order to ensure that " clear " shall not be indicated in a danger zone. Thermionic relays are used to amplify and rectify the currents flowing in the coil C. The power supply conductor may be used for the track conductors of the signal current, if desired, suitable falters being used to prevent interference by currents of other frequency.

Title: Improvements in or relating to wound coverings
IPC: D03D1/00
Filed: 1954-11-15
Abstract: To prevent bandages from sticking, they are made from threads that shrink on wetting and others that do not shrink or that shrink a smaller amount, whereby the threads execute small local contrary movements which interrupt the sticking process and create fresh capillary passages to absorb secretions.  The weave is such (see Group IX) that the shrinking threads are spaced from the surface applied to the wound.  Raw cotton is normally used, but scoured cotton is used when large quantities of secretion have to be absorbed; it is stated that a single layer of the fabric is sufficient.
