Patent FI-971078-A (FI)
Inventor: SARTOR LUIGI
IPC: C09J7/38
Filed: 1997-03-14
Abstract: A method and apparatus for simultaneously coating multiple thin layers of relatively viscous fluids, including pressure sensitive adhesives (PSAs), onto a moving substrate. The method of the present invention comprises the adjustment of the pressure gradients in the interface region between two confluent flows so as to avoid recirculation therein. In particular, the pressure gradient along the middle lip is regulated so as to not be excessively positive, in order to position the separating line between the top and bottom flows at a particular point on the die lips, thus enhancing stable flow. In the apparatus of the present invention, a step configuration is formed on the die lips so that the downstream lip steps away from the web in the direction of web travel. In another aspect of the invention, the pressure gradient at various locations in the bead is controlled by beveling the upstream and downstream lips. In yet a further aspect of the present invention, the viscosities of the two liquids being coated are matched at therelevant shear rates to promote good coating quality.

Title: Process for the production of 1.1.2-trichlorethane
IPC: C07C17/00
Filed: 1930-01-10
Abstract: 1.1.2-trichlorethane is obtained by causing a mixture of p acetylene, chlorine, and hydrogen chloride to react, risk of explosion being obviated by carrying out the reaction either in narrow or constricted spaces or in the presence of an adequate excess of acetylene or hydrogen chloride or foreign inert gases such as nitrogen or carbon dioxide.  Contact materials such as coke, chamotte, quartz, clay, rock salt, active carbon, silica, or pumice, impregnated or not with metallic salts such as mercuric chloride may be present.  The process may be carried out in apparatus such as that described in Specification 16620/12, [Class 2 (iii), Dyes &c.], for the production of dichlorethylene. When the initial gaseous mixture is explosive it is caused to react in a vessel filled with material such as coke breeze or sand heated, for example, to 200-250 DEG  C. Non-explosive mixtures are heated in the presence of contact materials to temperatures of, for example, 80-150 DEG  C.  The process may be made cyclic by returning the reaction mixture, after it has passed through a cooler or washer in which the trichlorethane is separated, into the reaction chamber with the addition of fresh chlorine and hydrogen chloride, acetylene being also introduced at another point.  A suitable small proportion of the circulating gas may previously be removed in order to diminish the content of foreign gases in the stream, or the circulating gas may be allowed to escape unregulated through a liquid seal.  It is desirable to increase the gas velocity locally at the point where the chlorine is introduced. Examples are given.  Small amounts of dichlorethylene, acetylene tetrachloride, and ethylidene dichloride are obtained as by-products.

Title: Improvements in the production of acetylene by incomplete combustion of hydrocarbons with oxygen
IPC: C07C2/78
Filed: 1955-01-14
Abstract: Acetylene is produced by an incomplete combustion of hydrocarbons with oxygen in which these materials are preheated separately and the preheated gases are supplied to a mixing chamber in which they meet at the inlet end at high speed, and the speed of the mixture is retarded towards the outlet end by conical widening of the mixing chamber, and the mixture is then supplied to a reaction chamber in which the reaction takes place in the form of a flame, and the products are rapidly cooled, wherein a safety device which automatically initiates safety measures in the event of an ignition in the mixing chamber receives its impulse from the pressure difference between the point at which the gases meet and a point further along in the direction of flow at which a small speed of flow prevails.  The safety device may receive its impulse from the pressure difference between the point at which the gases meet, and either the end of the conically widened part of the mixing chamber, or the reaction chamber or the surrounding atmosphere.  The safety measure employed may be a valve in the oxygen supply line to the preheater which is closed by means of electrical actuation. Specification 672,446 is referred to.

Abstract: 339,530. Lamer, S., and Skrak, J. Jan. 14, 1930. Spring power-storing machanism. - A footoperated motor for driving small drills and similar workshop uses is wound by a single depression of a treadle, which, by a series of gears and cables, stores power for a prolonged drive. The gears are arranged for varying the relative output of speed and power. When the foot lever 4 is depressed, it pulls down the lever 10 which in turn pulls the lever 21 by the catch 24.

Title: Improved process for the preparation of gel particles
IPC: B01J2/08
Filed: 1946-01-15
Abstract: Microspherical gel particles useful as catalysts are produced by the admixture of at least two solutions of the appropriate sol-forming components, at least one of the solutions being in the form of a spray, the sol particles so formed being allowed to set to gel particles.  Two solutions may be employed as sprays or one solution may be sprayed into the agitated solution of the other.  In the former case, the two sprays may be formed in an atmosphere of air, nitrogen, steam, ammonia, vapours of organic compounds such as hydrocarbons, butanol and other alcohols, acetic acid and other acids, morpholine, or mineral acid vapours such as hydrochloric acid and the resulting particles collected in a liquid such as water, an aqueous solution of a water-soluble compound or organic liquids such as hydrocarbon oils or butanol, of density less than that of the particle and immiscible or partially miscible with water.  Such a collector liquid may also contain a surface-active agent. Alternatively, the sprays may be introduced beneath a suitable liquid such as a mineral oil or butanol.  According to examples, silica-alumina gel is formed by spraying aqueous solutions of sodium silicate and aluminium chloride into the air or by allowing a spray of sodium silicate to fall into an agitated solution of aluminium chloride, while silica gel is produced by mixing a spray of aqueous sodium silicate with a spray of aqueous sulphuric acid.

Abstract: 995,558. Tyre vulcanizing presses. K. ZANGL. April 19, 1962, No. 15311/62. Heading B5A. [Also in Division B1] A protective mixture of water and glycerine is injected into the compressed air flowing into the pressure bag of a tyre vulcanizing press. In Fig. 1, compressed air passes through a valve 31 and depresses a piston 7 in a pressure cylinder 6, whereby the mixture is forced past a non-return valve 51 into a mixer 9 where it is atomized by the main flow of compressed air. The setting of pressure regulator 21 determines the quantity of liquid injected. At the end of the vulcanizing process, the system is depressurized and the cylinder 6 is refilled when the piston 7 is lifted by spring 8, drawing a further supply of liquid from a container 42, through a one-way valve 41. In another embodiment (Figs. 2, 3, not shown) liquid is fed under gravity through a magnetic valve 41, held open for a short period by a time relay, into a mixer 9, after which valve 41 closes and a valve 22 opens to admit compressed air. This sequence automatically follows the press closure.
