Title: Improvements in automatic regulators
IPC: G05D13/00
Filed: 1927-04-12
Abstract: 291,923. Wingfield, B. R., and Wingfield, B. T. April 12, 1927.

Title: Filling of containers
IPC: B67C3/26
Filed: 1973-03-01
Abstract: 1422213 Dispensing measured quantities into containers FMC CORP 1 March 1973 [17 March 1972] 10136/73 Headings B8N and B8T A method of filling a container with liquid comprises providing a supply of liquid maintained at superatmospheric pressure, confining a measured quantity of said liquid within a measuring chamber, increasing the volume of the measuring chamber to reduce the pressure of the measured quantity of liquid to approximately atmospheric pressure, and releasing the measured quantity of liquid from the measuring chamber into a container at atmospheric pressure. Apparatus for carrying out the method comprises a driven port 37, Fig. 2, carrying a pusher ring 41 for moving containers C in a circular path along tracks 26 and also supporting a reservoir 48 which contains liquid at superatmospheric pressure. A rim 49 on the reservoir supports filler valves 50 each connected to the liquid reservoir by a flexible conduit 53 and lying in coaxial relationship with a container C in use of the apparatus. Each filler valve comprises a cylindrical body 58, Fig. 3, an inlet valve 90a and a foot valve 91a. Vertical movement of the body 58 and of the valves 90a and 91a to open or close them is effected by cam followers 78, 99, and 106 running on cam tracks 84, 100, and 108 respectively. In operation a container C, Fig. 1, is fed by a feed screw 115 and star wheel 29 into a pocket 42 of the pusher ring 41 and on to the tracks 26. At this time the associated filler valve 50, Fig. 3, is in a position in which the body 58 is raised and the valves 90a, 91a are closed. As the container moves along the tracks the valve 90a opens and the body 58 and closed valve 91a are lowered into the container, the body at this time 58 filling with liquid from the reservoir. When a predetermined quantity of liquid is in the body 58, Fig. 7, the valve 90a is closed and the body 58 then lowered slightly to increase the enclosed volume and reduce the pressure of the liquid to atmospheric. The valve 91a is then opened and the body 58 raised to discharge the liquid into the container. During this operation the container C is also raised by the tracks 26 but at such a rate that the lower end of the body 58 is below the liquid surface to prevent foaming. When all the measured quantity of liquid has been discharged the valve 91a again closes Fig. 11, so that the valve 50 is in its original state. The tracks 26 tilt the container C during filling to counteract the effect of centrifugal force on the liquid. The filled container is removed by a shoot 43, Fig. 1.

Title: Process for the production of alkali soaps, including ammonium soap, and for obtaining fatty acid therefrom
IPC: C11D13/04
Filed: 1928-04-04
Abstract: 320,331. Graubner, V. April 4, 1928. Soaps, processes and apparatus for making; fatty acids and glycerine, obtaining.-Soaps are obtained by conducting molecular proportions of alkali lye and olive oil, tallow, or other fat under pressure in thin streams in a zigzag path formed by external ribs on a heating member and internal ribs on a casing while the temperature and pressure are substantially constant. Fatty acids may be obtained by decomposing the soap, e.g. by distributing it into a concentrated aqueous solution of the sulphate of the soap base maintained acid by addition of sulphuric acid. The fatty acid forms an upper layer and is separated. The glycerine is extracted from the salt solution or the separated salt by a low-boiling solvent such as ethyl or methyl alcohol. In an example, 263 kg. of ammonia water containing 23 per cent NH3 and 1 metric ton of neutral fat heated to 80-90‹ C. are mixed in a centrifugal or piston pump or injector r and forced through a pipe 4, a vessel B, and a zig-zag path formed by internal flanges m on a casing 2 and external flanges o on a steam pipe 3. The mixture passes through a vessel B<1> and through one or more similar apparatus C<1>, C to a pipe 5 and diffuser nozzle p having an outlet diameter of 1.0-1.5 m.m. and discharging into a hot saturated solution of common salt. Soda soap, glycerine, and ammonium chloride are thus produced.
