Title: Improvements in a process of heating liquids electrically
IPC: F24H1/10
Filed: 1919-12-09
Abstract: 159,654. Abogado, L. G. Dec. 9, 1919. Heating by electricity.-In a flow heater, the liquid is passed over one surface of an electrode, and then into a space between that and another electrode, the liquid flowing in a non-whirling spiral film, which is preferably of uniform thickness. After the liquid has been heated by the passage of current there-through, the supply of liquid is stopped, and the liquid remaining is heated to a higher temperature, the resulting vapours being removed in a spiral path. As shown, the liquid passes through passages D in a plug C into the space between the electrodes O, 0' and a container B, then between the electrodes, and through perforations, not shown, in the top of a tube P to the outlet L. The electrodes are formed with bends d so as to overlap. and are mounted between grooved plugs C, E. A heat-retaining mass Z, such as an hydraulic cement made from cement, asbestos, bone-ash and bichromate of potash, is secured between two discs X mounted on a rod F, and serves to equalize the temperature. Connection with the electrodes is made by means of rods T welded to the bends, and passing through the plug E. The tube P is of conducting material, and may be connected with one electrode by a contact b on a rod a, so as to reduce the resistance of the circuit. The container may be coated on the inside with pitch to prevent oxidation, and is secured between a lower casing A and an annular casing H with a cover M and a cap K. In a three-phase arrangement three electrodes have bends at 120‹ apart. In another arrangement, the electrodes and container are of rectangular shape. The electrodes may be of metal or carbon.

Title: Improvements in or relating to automatic weighing balances
IPC: G01G13/00
Filed: 1930-10-21
Abstract: 356,015. Automatic-feed weighers. LERNER, F., 28, B³rgerspitalgasse, Vienna. Oct. 21, 1930, No. 31604. Convention date, July 29. [Class 143.] In an automatic weighing machine wherein two weighing receptacles are alternately filled through a distributing shoot and the balance beam, after reaching its position of equilibrium, is tilted by means of a running weight, the distributing shoot is reversed by means of electromagnets energized by the tilting of the balance beam. The material flows on to a distributing shoot 18 pivoted loosely, upon a shaft 15 and passes into a scale pan 21 carried by a weighbeam which is constituted by two parallel tubes 1 each containing a ball 20. When the weighbeam tilts under the added impetus of the rolling balls 20, a fork 7, 8 closes two spring contacts 12 and thereby energizes an electromagnet secured adjacent the end of the shaft 15. A soft iron plate secured to the shaft is attracted into line with the electromagnet and imparts a rotation to the shaft. A frame 17 secured to the shaft rocks therewith and first closes the end of the shoot 18 and then rocks the shoot so as to lie upon a stop 10 and feed the material into a scale pan (not shown) at the other end of the weighbeam. During the rotation, a crank pin 24 carried by the shaft 15 rocks the spring contacts 12 into a position clear of the fork 7, 8 and thereby opens the circuit of the electromagnet, the cycle of operations being repeated in the opposite direction. A partition may be fitted in the middle of each tube 1 and a ball provided at each side thereof.

Abstract: 246,447. Farkwerke vorm. Meister, Lucius, & Br³ning. Jan. 22, 1925, [Convention date]. Addition to 240,852. Void [Published under Sect. 91 of the Act]. Dye preparations.-The varnishes described in the parent Specification and consisting of a pigment dye intimately united with a resin or a solid fatty acid, suspended in a cellulose varnish, are modified by intimately mixing the pigment dyes or lake colours in a dry state with a resin or a fatty acid, and then finely subdividing this mixture together with an animal, vegetable, or mineral oil or other softening agent by mechanical means. The varnish-lake thus formed may be dissolved in a cellulose ester or ether varnish. The softening agent may be an oil varnish comprising an animal, vegetable, or mineral oil together with an artificial or natural resin, or a body applicable for rendering films of cellulose ester or ether soft, inasmuch as such bodies form oil varnishes with artificial or natural resins. In examples, the dyestuffs Hansa Yellow G, Hansa Red B, and Indanthrene Blue R.S. are each mixed with colophony, castor oil, and linseed oil, and the mixtures are repeatedly passed through a colour-grinder. The pastes obtained are then incorporated with suitable cellulose varnishes. The products may be used for printing or staining paper, leather, fabrics, &c. by brushing on or spraying, and produce a washablecovering. Leather so treated may be polished or dressed (curried) by usual methods, and paper may be subsequently impressed.
