Title: Improvements in or relating to the manufacture of artificial silk
IPC: D01D5/14
Filed: 1927-07-15
Abstract: 296,856. Brysilka, Ltd., and Schubert, F. W. July 15, 1927. Apparatus for making filaments. - In the manufacture of artificial silk by the stretch-spinning process, a. spinning funnel wider at the bottom than at the top is employed. In this way room is provided for the dispersal of the comparatively strong currents and eddies created at the bottom of the funnel (which dips into the coagulating liquid in the usual bath or trough) by the coagulated thread formed by the filaments ejected from a spinneret at the top of the funnel. Fig. 1 shows a suitable form of funnel, and Fig. 2 shows a modified form suitable for a two-liquid process. In the form shown in Fig. 2, a lip 2, provided between the upper part 3 and the flared and tapered lower part 1, arrests the upward flow of the stronger coagulating liquid from the trough, while the conical shape of the part 3 facilitates the downward flow of the weaker coagulated liquid, which may be supplied by a pipe associated with the spinneret. It is preferred to use longer funnels for threads of coarser counts.

Title: Apparatus and process for removing solid and gaseous pollutants from a gas
IPC: B01D47/06
Filed: 1975-05-05
Abstract: 1494789 Scrubbing gases ENGELHARD MINERALS & CHEMICALS CORP 5 May 1975 [6 May 1974] 18808/75 Heading B1R A process for removing solid and gaseous pollutants from a gas comprises causing a scrubbing liquid to flow into a first inner contact zone eccentrically disposed within a second outer contact zone so as to divide the outer zone into an expansion flow passage and a restricted flow passage, causing the gas to be scrubbed to flow into contact with the liquid in the inner contact zone and into the outer zone so that it passes sequentially through both the expansion flow passage and the restricted flow passage whereby at least a portion of the solid pollutants in the gas may be removed in the outer zone and at least a portion of the gaseous pollutants may be removed in the inner zone. In the apparatus shown in Fig. 2, gas fed through inlet 40 flows through expansion flow passage 18, restricted flow passage 20, and into the inner contact zone 22. Nozzles 34a and 34b spray scrubbing liquid into both the inner and outer zones to clean the gas, which leaves through outlet 42. In this embodiment, gas flow is counter-current to the scrubbing liquid in the inner contact zone. In the embodiment of Figures 6-8 (not shown), which uses identical apparatus, gas is fed first into the inner contact zone in co-current flow to the scrubbing liquid before passing through the expansion flow passage and restricted flow passage. Figure 4 shows a horizontally disposed apparatus in which the gas flows through inlet 40a to expansion flow passage 18a and restricted flow passage 20a, and then into inner zone 22a. Nozzles 34a' and 34b' spray scrubbing liquid into the inner and outer contact zones. In Figs. 9-10 (not shown), identical apparatus is used, but the gas is fed first into the inner zone. In all the embodiments, gas flow through the apparatus may be facilitated by use of a fan or a suction device. The inner contact zone in each case is packed with conventional surface contact elements such as glass, metal or plastic rings, rods, saddles, Tellerettes, Pall rings, honeycomb or egg crate material, Raschig rings, porcelain rings.

Title: Improvements in or relating to mass flow meters
IPC: G01F1/80
Filed: 1957-06-14
Abstract: 856,204. Flow-meters. BOPP & REUTHER G.m.b.H. June 14, 1957 [June 14, 1956; Aug. 23, 1956; Sept. 1, 1956; Oct. 17, 1956], No. 18833/57. Class 40 (1). [Also in Group XXIX]  A mass flow-meter comprises a rotor 2 (Fig. 2), running at a constant speed, arranged to be subjected to the flow of the medium to be measured in a direction perpendicular to its axis of rotation and means for deriving a measurement of the force, or a measurement proportional to the force, tending to move the rotor in a direction perpendicular to its rotational axis and the fluid flow. As shown in Fig. 2, the rotor is arranged in a cylindrical housing 1 and the fluid passes from a branch 5 to flow tangentially over a rotor 2 housed in an annular space 7, the fluid being discharged through a branch 6. The rotor 2 causes a velocity difference and consequent pressure difference in the upper and lower parts of the annular space 7. A gauge 12 records this pressure difference which is proportional to # V Un where # is the density of the medium to be measured, V is the flow velocity of the medium and Un is the peripheral velocity of the rotor. Since the speed of the rotor is maintained constant the pressure difference will be proportional to the mass flow. The surface of the rotor may be roughened by sand blasting to increase its friction and thereby enhance the velocity difference above and below the rotor. Alternatively the outer surface of the rotor may have blades extending parallel to the rotational axis or the rotor may have radially-extending annular discs mounted on its periphery. In other modifications the unsymmetrical pressure distribution is transmitted mechanically to a bellows and the pressure difference measured by a moving weight controlled by an opposing compressedair pressure source actuated by a turbine or by an electric motor. In a further modification shown in Fig. 7, the mass flow is derived electrically from a mercury differential pressure gauge 12 provided with teletransmitter resistances 34 and a tachometer generator 31 mounted on the rotor shaft. To regulate the mass flow the flow-meter is combined with a regulating valve 44 (Fig. 8). A differential pressure transmitter 40 actuates the valve 44 to regulate the flow in the whole duct 42, 43. The speed of rotation of the rotor 2 is controlled by variable gearing 41. The transmission of the variable gearing may be effected through a second mass meter and transmitter. If the two mass flows are thereafter combined, the entire installation acts as a mixture regulator. It is thus possible to regulate a flowing medium to a constant density.

Title: Improvements in a process for making shaped, rapidly and easily soluble mixtures of soaps and persalts
IPC: C11D9/16
Filed: 1931-07-01
Abstract: Stable and readily-soluble soaps containing persalts are made by saponifying fatty acids at a low temperature with approximately but no more than double the amount of calcined soda necessary, and adding the persalt before the saponification is completed. Hydrocarbons insensitive to oxygen, and borax, sodium triphosphate, pyrophosphate, bicarbonate, or silicate may be added at the same time.  Part of the soda may be replaced by potash or potassium carbonate to reduce brittleness, or liquid grain soap may be added to the product.  The products may be powdered, be extruded to form threads, filaments, wool, or tiny needles, or be rolled to platelets or to films which are scraped off the rollers by knives or needles.  In examples: (1) 70 kg. of split coconut oil fatty acid and 30 kg. of split tallow oil fatty acid are saponified with 30 kg. of calcined soda and 5 kg. of potash or potassium carbonate at 35 DEG  C.; just before the mass becomes viscous 12-13 kg. of sodium perborate are added; when nearly cold the mass is rolled to platelets or strips.  (2) 100 kg. of a mixture of split fatty acids from hardened palm kernel and ground nut oils are saponified at 35 DEG  C. with 33 kg. of calcined soda and 10 kg. of potash or potassium carbonate; just before the mass becomes solid a doughy mixture of 14 kg. of sodium perborate with 14 kg. of sodium silicate is added; when saponification is almost complete the mass is rolled to form strips and then pressed to rods from which platelets are scraped off by rotating knives.  (3) 100 kg. of distilled fatty acid mixed with 22 kg. of benzine, xylene, or hydrogenated hydrocarbons are saponified as in example (1); 16 kg. of sodium perborate are added.
