Filed: 1937-02-26
Abstract: 496,382. Refrigerating. KLEIMENOFF, J. Feb. 26, 1937, No. 2265. [Class 29] The circulation of cold brine through a pipe system in a chamber to be cooled is effected by the difference in concentration of the brine in interconnected vertical legs of the pipe system. As applied to a railcar, the pipe system includes legs 5, 7 connected at their lower ends to watertanks 1 having valved overflow pipes 3 and ice bunkers a, b, the upper end of the leg 7 being provided with a valve 14 and connected to a salt container 6 having a water-filling funnel 6a, while the upper end of the leg 5 is connected to a pipe coil 4 connected by a pipe, having a valve 13, thermometer 12, Venturi flow meter 11, and a byepass valve 8, with the salt container. The system may be operated at atmospheric pressure, in which case the cover of the tank 6 is removed and the ice bunkers and the valves on the pipes 3 closed. Initiation of the brine flow in the direction shown is effected by first closing the valve 13 and opening the valve 14 so that the leg 7 becomes full of highly concentrated brine. The valve 13 is then opened and circulation of the brine, which is cooled and diluted in the tanks 1, begins up the leg 5 and through the coil 4 to the salt container where it is reconcentrated and returns to the leg 7. The rate of flow of the brine may be varied by adjusting the valve 8 so that a part of the brine passes through the byepass 9 to the leg 7. It is stated that the system may be operated at sub-atmospheric pressure by closing the container 6, which is provided with a vacuum gauge 10, and opening the ice bunkers and the valves on the pipes 3.

Title: Improvements in or relating to devices for measuring ultra-high-frequency electric power
IPC: G01J5/20
Filed: 1948-01-26
Abstract: 633,609. Power measurements ; temperature variable resistances. SPERRY GYROSCOPE CO., Inc. Jan. 26, 1948, No. 2329. Convention date, Jan. 24, 1947. [Class 37] Apparatus for measuring high frequency power comprises a filamentary temperaturevariable resistance 12, Fig. 3, coaxial with and connected at one end to the inner conductor 41 of a coaxial line 40, its other end being connected to a conductor 31 extending across the outer conductor 42, the inner conductor being thicker than the resistance 12, and the outer conductor being reduced in diameter opposite the junction of the inner conductor and the resistance. The effect of this reduction in diameter is shown to be to add a capacitance in parallel with the line, and this is chosen to compensate for the inductance of the resistance 12 at high frequencies and thus maintain the matching of the line to its termination over a wider frequency band ; as a consequence the voltage standing wave ratio is maintained small. The resistance 12 is mounted between discs 30, 31, Fig. 2, the discs being joined by an insulating cylinder 32 which may be evacuated. The disc 30 has a plug 33 for connection to the inner conductor of the coaxial line, and the disc 31 is flexible and preferably gripped between threaded members 47, 50, Fig. 3, forming a plug having an insulating covering 45 and adapted to fit into the outer conductor 42. The variation of resistance 12 caused by its rise of temperature due to high frequency power is measured on a bridge, Fig. 1 (not shown).

Title: Process for the production of valuable organic compounds and in particular liquid hydrocarbons by treatment of carbonaceous materials with hydrogenating gases
IPC: C10G1/08
Filed: 1935-01-25
Abstract: <PICT:0450969/III/1> In the treatment of carbonaceous materials with hydrogenating gases in tower like reaction vessels, a uniform distribution of hydrogen over the cross section of the reaction vessel is obtained by subdividing the vessel in a direction parallel to the axis thereof by substantially vertical walls in such a manner that a noninterrupted connection or a connection interrupted in a few places only exists between the spaces created by the subdivision over substantially the total height thereof.  The reaction chamber c is divided into spaces r by partition walls b mounted on tubes a so as to have a star shaped cross section and to provide uninterrupted intermediate spaces d.  Heating or cooling media may be passed through the tubes a.  The partition walls may be constructed of materials resistant to hydrogen and to corrosion, e.g. ceramic materials or a steel containing chromium, molybdenum, titanium or aluminium.  Temperature regulating agents, e.g. hydrogen, oil, or the carbonaceous material undergoing treatment may be introduced through perforated pipes or nozzles into the reaction chamber at different levels.  Catalysts particularly sulphides applied according to Specification 379,335 may be used or the metals molybdenum, tungsten, vanadium, rhenium, manganese, titanium, tin, lead, iron, or cobalt or their compounds, e.g. oxides, hydroxides, halides or phosphates.  A petroleum residue boiling above 325 DEG  C. is admixed with 1 per cent brown coal semi-coke which has been activated with water vapour. treated with sulphuric acid, and impregnated with ammonium molybdate. The residue is then heated with hydrogen in a preheater to 470 DEG C., under 200 atmos. pressure and passed into a cylindrical reaction vessel provided with star shaped walls as shown in the Figure, forming nearly-closed reaction spaces of 200 sq. cm. cross section. After separation of the products in a separator and stripping the vapour products 92 per cent of a distillate boiling below 325 DEG  C. is obtained.  Specification 430,174 also is referred to.

Abstract: 195,210. Hargreaves & Co., Ltd., H., and Johnson, J. E. Jan. 27, 1922. Cylinders.-A uniflow engine has an auxiliary clearance chamber communicating with the main clearance space through a passage controlled by an automatically-operated valve so that the communication is established or severed respectively when the pressure in the clearance space is excessive or normal. A rotary or piston valve F controls ports P connecting the cylinder-clearance space A with an auxiliary chamber N, and has a differential valve-stem E, D, D<1> working in an auxiliary cylinder H<2> open to the atmosphere. The annular space R between the heads E, D communicates through a small hole J with the atmosphere to ensure gradual action and with a passage C connected by an automatic non-return valve B with the main clearance space A. Upon excessive pressure the valve F is opened by steam supplied to space R and is locked by a ball or spring detent G. When the cylinder pressure falls, the valve B closes, and the atmospheric pressure in H<2>, upon the detent G being released by hand or automatically, operates the valve F to close the ports P. The valve F may be hand-actuated.
