Title: Improvements in the separation of propane and propylene from gas mixture
IPC: C07C7/11
Filed: 1938-02-14
Abstract: Propane and/or propylene are separated from gas mixtures also containing other hydrocarbons, such as methane, ethane and ethylene, by washing with liquefied normally gaseous halogenated hydrocarbons and recovering the propane and/or propylene from the washing agent. Methyl, ethyl, and vinyl chlorides are specified washing agents. Natural, distillation, and cracking gases, or waste gases from the hydrogenation of carbonaceous substances may be treated.  If hydrocarbons of more than 3 carbon atoms are present, they are also washed out unless previously removed.  The halogenated hydrocarbons may be used mixed with each other or with other liquid solvents. Washing is preferably effected at increased pressure, when ordinary temperature may often be used. At ordinary pressure, the temperature is generally just above the boiling point of the hydrocarbons, e.g. -20 to -45 DEG  C.  In examples, mixtures of propane and ethane or propylene and ethylene are treated in three consecutive washers with ethyl chloride at -43 DEG  C.  On heating the washing agent to 0 DEG C., the absorbed gas, mainly propane or propylene, is expelled.

Abstract: 852,931. Electroplating. MOND NICKEL CO. Ltd. Feb. 12, 1958 [Feb. 20, 1957], No. 4628/58. Class 41 In a nickel plating process using a halide-free plating bath an insoluble anode is used comprising a core of metal or alloy, preferably wrought nickel, and an electro deposited layer of nickel of low anode current efficiency produced by depositing from a bath free from organic impurities or additions capable of depositing sulphur. Alternative materials for the core are cast nickel, iron, copper, aluminium, zinc, tin, antimony, bismuth, or alloys, including nickel-copper, iron-nickel, copper-nickel, tinzinc, tin-bismuth, tin-lead, antimony-bismuth, bismuth-tin, and zinc-aluminium. The anode is preferably used with a sulphate or sulphamate bath which is substantially free from organic additives in addition to being halide-free, and which may be shaped for use, closely spaced from the cathodes, in the plating of pipes, tubes, rolls, strip or wire, and in the electroforming of complicated shapes. Examples describe the use (1) of a nickel bar anode, prelimarily cleaned, treated anodically in 25 % sulphuric acid, and then briefly treated cathodically, for internally nickel-plating the interior of a pipe in an allsulphate bath containing boric acid, and (2), of a similar bar for plating a pair of nickel sheets.

Title: An improved method of and means for indicating the amount of liquid, granular or pulverulent material in a tank
IPC: G01F23/16
Filed: 1937-02-18
Abstract: 471,720. Indicating liquid - levels. NEUMANN, G. Feb. 18, 1937, Nos. 4940 and 4941. Convention dates, Feb. 18, 1936 and June 22, 1936. [Class 123 (i)] [Also in Group XIX] The volume of liquid, granular or pulverulent material in a tank 1 is measured by connecting through pipes 4, 4a the tank and an auxiliary vessel 3 at regular intervals to the same source of pressure and using the difference in the rate of pressure change in the two vessels to actuate an indicating device. The periodical connection with a pressure source is provided by a rotating valve 6 communicating alternately with the source and the atmosphere, and the ratio of the flow resistance of the two pipes 4, 4a may be varied by an adjustable needlevalve 35. The pressures in the two vessels act on opposite sides of a diaphragm 11 which according to its direction of movement closes contacts to drive the rotor 27 of an electric motor in one direction or the other and thus move up or down a pointer 31 on a nut 30, which also moves a piston 34 to equalize the pressures in the two vessels. The motor circuit is periodically opened, while the valve 6 communicates with the atmosphere, by a cam 24 engaging a spring contact 22. The vessel 3 may have an invariable volume, the valve 35 being connected to the nut 30. On an aircraft the pressure may be obtained by utilizing the wind of travel. Alternatively, the cock 6 may be dispensed with and the pressure changes produced by a reciprocating piston. The diaphragm may operate through hydraulic or mechanical transmission. In a modification, the needle-valve 35 is omitted and the two vessels communicate with cylinders containing pistons periodically reciprocated by the same driving device.

Title: Improvements relating to the heating and ventilation of motor vehicles
IPC: B60H1/00
Filed: 1953-02-23
Abstract: 730,421. Ventilating vehicles. DAIMLERBENZ AKT.-GES. Feb. 23, 1953 [Feb. 23, 1952], No. 4978/53. Class 137. [Also in Group XIII] Relates to heating and ventilating systems for vehicles in which fresh air in passing to the vehicle space is heated by a heat exchanger 2 through which flow: a fluid heating medium such as the hot water of the en gine cooling system According to the in vention one portion of the air is heate( by that part of the heat exchanger a which the heating medium enters and is thereafter directed to one part of the vehicle space and another portion of the air is heated by that part of the heat exchanger at which the heating medium flows out and is thereafter directed to another part of the vehicle space. In the form shown the heat exchanger 2 is provided with inlet and outlet conduits 3, 4 respectively for the heating medium. The heated air is collected in a duct 5 which is provided with partition walls 6, 7 and a pivoted valve member 11 as shown. In the position indicated by full lines, the more highly heated air passing through the lower part of the heat exchanger flows beneath the wall 6 and valve member 11 to a duct outlet 13 leading to the lower part of the vehicle space, e.g. the foot space, whilst the air which receives less heat by flowing over the coolest part of the heat exchanger flows over the top of wall 6 and valve member 11 to an outlet 12 leading to the upper part of the vehicle space, e.g. the windscreen or side windows. On operation of the member 11 to the position indicated by chain lines, the wall 7 becomes effective and also the opening 13 is throttled by a part 10 of the valve member 11 so that the quantity of air passing to the lower part of the vehicle space is reduced, but becomes more highly heated due to its passage over a greater area of the heat exchanger surface. At the same time the quantity of air flowing to the outlet 12 is reduced due to the how reduced cross-section of that part duct through which it flows. It is stated that .temperature differences of 5 to 8 between the upper and lower parts of the vehicle space may be maintained and also that when the heat exchanger is disconnected draughts are avoided in the vehicle space by setting the valve to the position indicated by chain lines.
