Title: Method and apparatus for dividing the exhaust steam of piston engines
IPC: F01K19/08
Filed: 1923-02-20
Abstract: 210,637. Backhaus, H. Feb. 20, 1923. Exhaust, treating.-The, exhaust is divided into two parts; the first passes to a reservoir closed by a non-return valve for further use; the second goes to the atmosphere or to a condenser which may be relatively small. The exhaust first passes through a contracting and expanding nozzle 2 and valve 3 into a reservoir, the pressure in which is greater than the back-pressure on the engine, until its pressure falls and the valve 3 is automatically closed; the remaining exhaust then passes through a space 5 to the atmosphere or a condenser.

Title: Process for the filtration of spinning solutions of high viscosity
Inventor: PERLT GUNTHER
IPC: D01D1/10
Filed: 1965-02-08
Abstract: 1,090,834. Filtering spinning solutions. INSTITUT FUR CHEMIEANLAGEN. Feb. 8, 1965, No. 5325/65. Heading B5B. Spinning solutions of high viscosity, particularly solutions of polyacrylonitrile in solvents such as dimethyl formamide, are filtered through filters of a type adapted for cleaning the filter element either by back-washing the element with the spinning solution solvent or a liquid miscible therewith or by passing a current of gas under pressure through the element in a direction opposite to the filtration direction. In the filtration system two filters are arranged in parallel in such a manner that while filtration is proceeding in one filter the other filter is cleaned as above. The spinning solution is filtered at a temperature of 50‹ to 95‹ C. and at a pressure (at the inlet side of the filter element) of 3 to 11 kg. per square centimetre. The filter medium used is of a non-textile nature and is either woven, perforated or sintered. It may be wire gauge, an unglazed porous ceramic material or a sintered metal material of pore size ranging up to 100 millimicrons. The filter element may be coated on its inlet side, prior to filtration, with a layer of a filter acid, which may be fire-clay, powdered glass, powdered quartz or a finely divided polyester, but is preferably diatomaceous earth. The coating may be effected by means of a suspension of the filter aid in a carrier liquid, preferably hot dimethyl formamide. The filteracid coating removed from the filter element by back washing or blowing down with pressurized gas may be mixed with a fresh portion of dimethyl formamide and the resulting suspension used for the coating of the filter element of the same or another filter. This may be repeated until the filter aid becomes so contaminated with impurities filtered off from the spinning solution that it must be discarded. The spent filter aid is then separated from the carrier liquid, preferably by means of a centrifuge and the carrier liquid (dimethyl formamide) separated from the spinning polymer by fractional distillation.

Title: Improved means for the quantitative detection of carbon dioxide and combustible gases containing carbon
IPC: G01N33/00
Filed: 1921-02-18
Abstract: 179,696. Victoria Falls & Transvaal Power Co., Ltd., and Andrews, W. O. Feb. 18, 1921. Gas analysis.-The percentage of carbon dioxide present in a mixture of gases is estimated continuously by means of a suitable indicating liquid in which the carbon dioxide dissolves to an extent dependent on its partial pressure, so that the degree of acidity acquired by the water depends on the percentage of carbon dioxide present in the gas. A suitable indicator consists of litmus, rosolic acid, methyl red, or phenol red, dissolved in water with or without the addition of alkali or other substance to alter the range of sensitivity. The gases are pressed over or through the liquid and the proportion of carbon dioxide is read off from the resulting colour by comparison with a graduated colour scale. The invention may be applied to the estimation of combustible carbon gases in a mixture by first removing carbon dioxide or other acid or alkaline gases, and then causing the residual combustible gases to undergo combustion, for example by passage through a vessel containing an electrically heated spiral and estimating the carbon dioxide as above. In the apparatus shown, the gases pass through a water trap i into an absorber l for removing interfering gases, thence to a combustion chamber o, and finally into the indicating- liquid s. An ejector b serves to draw a continuous stream of gases through the apparatus. In the simple estimation of carbon dioxide in a mixture, the absorber l, the combustion chamber o, and the water-trap i are dispensed with, and a vessel, containing a solution for absorbing sulphur dioxide &c., is substituted therefor.

Title: Improvements in devices for measuring small electric capacities

Filed: 1938-02-23
Abstract: 490,651. Capacitance measurements. SOC. ANON. REO. Feb. 23, 1938, No. 5786. Convention date, March 3, 1937. [Class 37] An instrument for measuring small capacitances with alternating current comprises a thermionic valve having three or more electrodes, in which the series of inter-electrode spaces is employed as a capacitance potential divider so as to obtain changes in the mean negative potential of the grid, and therefore of the mean value of the anode current, when the unknown capacitance is connected in parallel with one of the inter-electrode spaces. In the apparatus shown a triode T is supplied with alternating current and arranged to operate as a rectifier, so that a pulsating current flows in the anode circuit. A second rectifier T<1> supplies a pulsating current of equal amplitude but opposite phase to that in the valve T. Two calibrated variable condensers Cg, C<1>g of different values are connected across the grid and cathode of the valve T, the condenser under test being connected to terminals I, II, so that it is in parallel with the condensers Cg, C<1>g. A small variable condenser Ca is connected between the anode and grid of the valve T, and an ammeter A is connected in the common return lead of the valves T, T<1>. With the standard condenser Cg at maximum value, the reading of the ammeter A is brought to zero by adjusting the condenser Ca. The condenser to be tested is then connected to the terminals I, II, and the ammeter reading again brought to zero by reducing the value of the standard condenser Cg. The value of this reduction gives the capacitance of the condenser under test. Alternatively the condenser under test is connected, the standard Cg set at minimum value, and the ammeter reading reduced to zero by adjusting the condenser Ca. The condenser under test is then disconnected and the capacitance of the condenser Cg increased to bring the ammeter reading again to zero. The amount of this increase gives the capacitance of the condenser under test.
