Title: A method of coating a support material
IPC: C23C14/02
Filed: 1945-07-10
Abstract: In a method of coating a support material within a vacuum, the surface of the support material is subjected to a preliminary cleaning to remove foreign matter, has applied a protective covering of a liquid boiling in the range 200-400 DEG  C. and which does not react with the surface, and has a major portion of the liquid removed by a rubbing operation reducing the liquid covering to a thin film which is later removed by evaporation in an evacuated chamber, the cleaned surface being then coated by thermal evaporation while remaining in the same evacuated chamber. Suitable coating liquids are water-insoluble mineral oil, benzyl alcohol, phenyl ethyl alcohol, dibutyl tartrate, dibutyl phthalate or lanoline which may first be emulsified or dissolved in toluol. The rubbing operation to remove excess liquid may be performed with a lintless rag.  After the removal of the liquid film, which may be assisted by glow discharge, the surface may be coated with a metal or may be given a low reflection coating of a metallic salt, e.g. magnesium fluoride.  The support material may be glass, plastic, porcelain or a metal.

Title: Improved Automatic Means for Controlling the Gas Supply to Gas Heated Water Heaters.
Inventor: LOWE JAMES
IPC: F24H9/20
Filed: 1916-12-07
Abstract: 111,879. Lowe, J. Dec. 7, 1916 Fluid-actuated fuel valves for water heaters.- Relates to means for automatically controlling the supply of gas to gas-heated water-heaters of the type utilizing the differential water pressures set up in the supply or draw-off pipes when the water tap is turned on. The gas valve G is formed integral with a plunger Q interconnected by a lever J with a smaller plunger R, both plungers abutting against diaphragms D in chambers H. These chambers are connected by pipes P, P<1> to the water pipe B on opposite sides of a pressure-reducer valve A or the like. When the water tap is opened and water flows from right to left, the pressure transmitted through the pipe P' is smaller than that of the pipe P so that the plunger R is depressed against the action of the plunger Q and the gas valve is opened. When the flow of water ceases, the pressures in the pipes P, P' equalize, and the gas valve G gradually closes. The two plungers may be coaxially arranged above and below the gas valve, and the diaphragms may be dispensed with, provided the plungers are packed.

Title: Improvements in and apparatus for the separation of hydrocarbons from gases containing the same together with hydrogen
IPC: C10K1/18
Filed: 1931-06-20
Abstract: <PICT:0380164/III/1> In the separation of hydrocarbons from gases containing different proportions of hydrogen, the gas richer in hydrogen is first washed with a suitable solvent to lower the hydrocarbon content, preferably to the concentration of the gas poorer in hydrocarbons, the gases are then mixed and subjected to a further washing with a solvent for the hydrocarbons, if desired under different conditions.  The process is applicable to the gases obtained in the destructive hydrogenation of coals, tars, mineral oils, &c. so that the hydrogen obtained may be reused, or to the removal of hydrocarbons from gases used in the synthesis of ammonia. The washing oil used in the final stage may be used again for the washing of the gas richer in hydrocarbons.  The process may be carried out in a single or separate washers, and in the latter case, different pressures of the order of 200 and 25 atmospheres may be used.  Suitable washing liquids include destructive hydrogenation products, e.g. those boiling between 180-220 DEG  C. or similar hydrocarbon fractions, e.g. from gas oil or illuminating oil, synthetic products such as the higher fractions of the products obtained by the interaction of carbon monoxide and hydrogen, toluene and tetrahydronaphthalene.  For example, the gaseous products leaving a destructive hydrogenation chamber a in which brown coal tar is converted into middle oil and benzine under a pressure of 200 atmospheres are freed from condensible constituents in a stripper b. The effluent gases are compressed to 225 atmospheres and led into a circulating gas washer c containing for example a middle oil obtained in the process flowing in counter-current.  The washed gases are returned to the process.  The liquid products obtained in the stripper b are released to a pressure of 25 atmospheres in a vessel b<1>. The gases obtained are richer in hydrocarbons than the gases from stripper b, and are compressed to 200 atmospheres and washed in washer d, using oil from washer c which is not yet saturated with hydrocarbons.  The washed gases are introduced at the point f on the suction side of the compresser e and subjected to a further washing in the washer c together with the gases from the stripper b.  In the strippers b, b<1>, cooling agents having a temperature between 50 - 25 DEG  C. are employed, and the washing oil is kept at a temperature between 5 - 25 DEG  C.  The middle oil obtained in the chamber a is subjected to further destructive hydrogenation and converted into benzine.  The waste gases obtained by releasing the pressure on the benzine together with the gases obtained by releasing the pressure on the washing oil used in this process are preferably collected in vessels g, h and washed in the cyclic process with the gases obtained in the vessel b<1>.

Title: Signalling devices for producing intermittent flashes
IPC: H05B39/09
Filed: 1958-06-09
Abstract: 858,352. Visible signalling apparatus; marine signalling apparatus. NATIONAL RESEARCH COUNCIL. June 9, 1958 [June 10, 1957], No. 18369/58. Class 118 (2). [Also in Groups XI and XL (b)] In a signalling device, e.g. a flashing light buoy, the correct operation of the lamp is monitored either by a circuit receiving signals from a resistance in series with the lamp or a circuit receiving signals from a photo-electric cell illuminated by the lamp. In the event of lamp failure a motor is energized to bring a new lamp into circuit. The signalling circuit comprises, Fig. 1, an assymetrical multivibrator circuit, transistors TR1 and TR2, which produces a series of output pulses at the base of transistor TR3. Each pulse biases off TR3 whereby transistors TR4, TR5 and TR6 are switched to the conducting state and a signalling lamp 12 which is connected in series with TR5 and TR6 across the power supply produces a flashing signal. During the periods when the lamp is conducting the monitor amplifier, transistors TRA-TRE is energized via the conductor 29 and the emitter-collector path of TR5 and TR6 and the voltage drop across resistance R8, in series with the lamp, is applied to the base of TRA. As a result TRA and TRC are biased on and TRB and TRD are biased off, whereby TRE is held in a non-conducting state. In the event of lamp failure no voltage drop appears across R8 and the transistor bias states are reversed and TRE is switched at each signal pulse to the conducting state in which it energizes the motor comprising the electromagnet 20, armature 21 and ratchet-wheel 23. A lamp carrier 32, which is coupled to the ratchet-wheel, moves a new lamp 12<SP>1</SP> into the operating position. The photo-electric monitor Fig. 2 (not shown) (see Group XL (b)) produces a similar result. During daylight the signalling device is switched off by the current flowing through the photo-cell 34, exposed to the ambient light, and the electromagnet M. The lamp carrier 32, Figs. 4 and 6, comprises a rotatable turret, holding 4 lamps, which is journalled in an upper extension of the casing 33 and coupled to the ratchet-wheel of the magnetic motor by gears 45 and 46.
