Abstract: 215,250. Eikenroth, F. Aug. 31, 1923. Solid supply to liquid; removing sludge from generators.-The generating-chamber 12 open at the lower end, dips into the water in the. tank 1. Each charge of carbide falls on to a perforated plate 8, and while resting thereon is washed by the water in its backward and forward movements due to variations in gas pressure in the generating-chamber. The plate may be tilted, as by a system of rods 9, and discharges the residue on to a bottom plate 14 mounted on a vertical spindle 15; the residue eventually falls on to the sloping bottom of the tank, collecting at an outlet 16, which is opened at intervals by means of a hand lever 17. To regulate the feed of carbide, a flap valve 18 is placed below the discharge orifice of the carbide-container 4, and the valve is controlled by the motion of the gas. holder 6 through a lever-system 5.

Title: Supercooling of liquids
Inventor: BHATTACHARJEE NARAYAN PADA
IPC: B01D9/00
Filed: 1962-06-07
Abstract: A supersaturated solution of amino acid is obtained from an aqueous saturated or near saturated solution thereof by contacting the latter with a relatively cold inert immiscible liquid. Contacting may be effected by merely shaking up the liquid and the solution together, or turbulent streams of the liquid and solution may be contacted in a mixing chamber or carried along in a transfer duct, and thereafter separated settling, decantation or centrifuging. The method of the invention is said to be particularly suitable for the super-cooling of saturated aqueous solutions of racemic amino-acids for instance glutamic acid prior to seeding with crystals of the required isomer. In the particular example given, such acids at 100 DEG C. are super cooled to 70 DEG C. by intimate contact with 750% by volume of white spirit. Other suitable cooling liquids mentioned are light lubricating oil, decane and dodecane.ALSO:A supersaturated solution of amino acid is obtained from an aqueous saturated or near saturated solution thereof by contacting the latter with a relatively cold inert immiscible liquid.

Abstract: 1,018,337. Measuring fluid flow. COMMISSARIAT A L'ENERGIE ATOMIQUE. June 1, 1964 [June 4, 1963], No. 22509/64. Heading G1R. In an apparatus for measuring gas flows at pressures below atmosphere, such as pressures less than about 10<SP>-3</SP> mm. Hg, the gas is drawn through an adjustable orifice 4, such as an inis diaphragm Figs. 2, 3 (not shown), into a chamber 2 by a pump 5 and the pressure on each side of the orifice is measured by a differential pressure measuring instrument 7 and the pressure in chamber 1 is measured by a gauge 8. The pressure difference on each side of orifice 4 is measured for different openings and the value of such pressure differences are then calculated for infinite and unity conductance, and the actual flow rate is deduced from the difference between these two values. The pressure difference for infinite conductance or free passage of gas corresponds to the constant error of the apparatus and the pressure differences for unity conductance corresponds to the value of the flow measured with an ideal apparatus. The pump 5 may be a diffuser pump conbined with a primary pump. The instrument 7 may be two hot cathode ionisation gauges disposed on each side of the orifice 4; the ionic currents of the two gauges being arranged to break one another, at tube 9 from the discharge 10 of the pump 5 passes some gas to a reservoir 13 to be returned to the chamber 2 subsequently or direct to chamber 2 to maintain the pressure in the chamber 1 at the desired pressure.

The annulus 27 has an aperture sufficiently large as to not obstruct the gas return path and also to avoid sputtering, and may be formed with cooling fins, Fig. 7, which are canted so as to create turbulence in a fluid coolant passed over the surface of the tube. In the arrangement described a total of four bores 26 in each segment provide gas return paths, these bores being joined by slots to an axial discharge bore 24 as shown in Fig. 4. A complete laser assembly is shown in Fig. 1 in which the discharge tube is secured to copper supports 36, 37 by welding, the tube and supports being mounted between a cathode 21 and an anode 22, both with apertures. The generated radiation passes to external reflectors 16, 17 through Brewster-angle optical windows 52, 56 which are mounted on tubular members 53, 57.
