Title: Portable apparatus for holding and vaporizing liquefied gases
IPC: F17C9/02
Filed: 1946-03-27
Abstract: 610,003. Vaporizing liquefied gases. LINDE AIR PRODUCTS CO. March 27, 1946, No. 9549. Convention date, April 11, 1945. [Class 8 (ii)] A portable, heat-insulated, gas-dispensing apparatus comprises a liquefied gas vessel 10 connected by a gas conduit 24 near its top to a gas chamber 20 which in turn leads to a discharge conduit 13, and the gas conduit is provided with a trap to prevent the passage of liquefied gas in excess of that required to maintain the gas supply irrespective of the position of the apparatus. The trap comprises right-angled convolutions 26, 27, and the gas chamber 20 is formed as an annular space between the vessel neck 11 and a tube 15 of an electric immersion heater 16. A bellowspressed plate 21 and the discharge conduit 13 delivers the oxygen gas to its place of use. Charging of the vessel 10 with liquid oxygen is effected through a connector 40, stop valve 39 and a conduit 36 also provided with loops 41, 42 to trap liquefied gas in the event of the vessel being inverted, and so prevents unwanted transfer of heat from a heavy metallic headblock 12 to which the conduit 36 is secured. On the trap inlet 25 being submerged, transference from the vessel 10 to the chamber 20 of liquid oxygen in excess of that required to maintain the pressure in the chamber 20 against discharge through the conduit 13 is prevented by the gas pressure in the chamber 20. Conduits 43, 48 are connected to liquid level indicators. In a modification, the trapped conduit may be disposed entirely within the gas chamber; the conduit delivery being either at the side or base of the chamber. In a further modification, the trapped conduit delivers into a cup which is secured to the interior of the vessel, and has a tube surrounding the heating element passing through its base; the gas passes through orifices in the tube to the gas chamber formed by the annular space between the tube and the heater.

Patent GB-331220-A (GB)
Title: Improvements in and relating to the production of printing plates
IPC: B41C1/16
Filed: 1929-03-25
Abstract: 331,220. Trist, A. R. March 25, 1929. Printing-surfaces. - A printing-plate having mercurized non-printing areas is prepared from a plate comprising an electrolytically-deposited layer of nickel on a layer of chromium supported on a copper base, a colloidal resist being formed on the nickel, the exposed parts of which are dissolved by an etching-fluid adapted to harden the colloidal layer, then dissolving the exposed chromium by a fluid which will not affect the nickel, replacing the chromium with an amalgam of a noble metal, and finally removing the remaining nickel and colloidal material. The copper base, which may be a copper sheet secured to a base of a metal such as iron or to a base of non-metallic material such as artificial resin, hard rubber, or a casein product, has the chromium electrolytically deposited thereon, and the chromium is then activated, to render it suitable for electrolytic deposition of nickel, by immersing it as a cathode in an aqueous electrolyte comprising a solution of sulphuric acid and ammonium sulphate. A thin coating of light-sensitive material, such as " process " emulsion is applied to the nickel and an image is produced thereon, a screen being employed if desired. If this image is not the final one, it is developed with metol hydroquinome developer and exposed to actinic light to produce a final image. The final image is developed with pyrogallic acid or other developer adapted to harden the colloidal layer, the unexposed parts or those developed with the metol hydroquinone being washed away. Alternatively, if for direct printing, a layer of bichromated fish glue may be employed and developed in the ordinary way. The nickel exposed bv the removal of the unexposed colloid is dissolved with iron perehloride in spirit, the spirit serving to harden the colloid layer. The chromium is unaffected by the iron perchloride and is removed in a bath consisting of hydrochloric acid and glycerine, the plate being preferably included as a cathode in an electric circuit until solution of the chromium proceeds normally. The exposed copper areas may be mercurized if desired, and the nickel resists are removed by immersing the plate as an anode in a solution of hydrochloric acid, a, lead cathode being employed. Silver is then applied either chemically or electrolytically to the copper areas, and, if not already mercurized, the ink-rejecting areas are treated with chalk and mercury. According to one of the Provisional Specifications, the nickel exposed after developing the photographic image is removed by hydrochloric acid and glycerine with a cathode of an inert material such as lead, and the nickel resists are finally removed in a similar electrolyte. A single electrolyte, for the purpose of obviating separate baths, may be used.

Filed: 1984-06-08
Abstract: A process for the production of edible foam from flowable, pumpable substances, such as mixtures of whole eggs and sugar, egg white solutions or cream products, together with a gas such as air or nitrogen, is as follows. The medium (cream or egg white etc.) and gas are separately supplied in a volumetric ratio of at least 1:8 to a pump, esp. a spindle mixer or rotary piston pump, and are there thoroughly mixed together. The medium-gas mixture is then delivered from the pump at a pressure of 0.19 - 0.98 N/mm2 into a disperser tube, where foaming takes place. - The two constituents are pref. fed to the pump through separate lines containing throttle valves for regulating their individual flows. Preferably, the pump pumps predominantly air and the other medium acts also as a lubricant and receiving agent for the pump.

Title: Color demodulating circuit of video reproducer
Inventor: YAMASHITA SHIGEO
IPC: H04N9/455
Filed: 1983-01-07
Abstract: PURPOSE:To prevent the deterioration in the S/N ratio of a subcarrier signal for detection by demodulating a color difference signal included in an output of a signal synthesis means in response to a signal level of a chrominance carrier signal component to prevent the generation of cross color or hue error or the like. CONSTITUTION:A color subcarrier signal subject to phase modulation in response to an output of a two-multiplication circuit 6 becomes a subcarrier for detection and is phase-shifted in response to phase distortion of the chrominance carrier signal outputted from a subtraction circuit 2. Further, when an input level of the two-multiplication circuit 6 is small, an output of a signal level detecting circuit 10 goes to a low level and an output of a 1H delay circuit 12 from a signal switching circuit 11 is outputted selectively as the subcarrier signal for detection. Thus, even if the input of the 2-multiplication circuit 6 is small and the S/N ratio of the subcarrier signal outputted from a phase modulator 9 is deteriorated temporarily, the subcarrier signal outputted from the phase modulator 9 before 1H is outputted from the signal switching circuit 11 as the subcarrier signal for detecting supplied to an R-Y demodulator 7 and a B-Y demodulator 8.
