Patent BR-8001519-A (BR)
Inventor: WUST W

Abstract: A process for the continuous production of an aqueous, alkaline suspension of x-ray amorphous sodium aluminosilicate having a small particle size of at least 99% by volume of a particle size of less than 50 mu , suitable for conversion into zeolite sodium aluminosilicate of the smallest particle sizes, by mixing an aqueous sodium aluminate solution with an aqueous sodium slicate solution in the presence of excess sodium hydroxide solution at a temperature in the range of from 20 DEG  to 103 DEG  C., where the solutions being mixed have a mathematical total molar ratio of: 1.5 to 9 Na2O:1 Al2O3:1 to 7 SiO2:40 to 400 H2O consisting essentially of the steps of continuously passing one of said two aqueous solutions into the first zone of a progressively, separately zoned mixing area, continuously splitting the other aqueous solution into at least three partial streams, continuously passing the first of said partial streams into said first zone, continuously passing the mixed contents of said first zone into the second zone of a progressively, separately zoned mixing area, continuously passing the remainder of said partial streams separately into downstream zones of said progressively, separately zoned mixing area, where said mean holding time of the reaction mixture in each of said separately zoned mixing areas is at least 5 seconds and sufficient to effect substantial mixing of said contents.

Abstract: In a switch or relay and, more particularly, a power or auxiliary switch or relay with a contact system mounted in a housing, as well as a magnet system which actuates the contact system, considerable difficulties are encountered when the contacts of the contact system are disposed in at least two planes which are disposed at different distances from the mounting plane. In such a case, the contact connecting zones which are facing away from the mounting plane are covered by the wiring for the contact connecting screws which are further displaced from the mounting plane and therefore are not accessible. Since switches or relays of this type are usually installed in large numbers in rows and in a compact arrangement with respect to each other in switch or relay boxes, a predetermined standard width for the switches or relays should not be exceeded. The employed switch or relay boxes are subjected to considerable shocks during transport to the installation site, so that the total wiring and the firm seating of the contact connecting screws must be checked before operation. In order to enable a simple handling of the wiring possibilities for the contacts and to also enable alternate installation of the wiring on the upper or on the lower contact connecting screws, or vice versa, without increasing the limited width of the switch or relay boxes, as is the case in actual practice, regardless of the number of poles, the switch or relay chambers are laterally displaced with respect to each other within the common flat side faces of the housing, while simultaneously maintaining the predetermined width from plane to plane, so that each contact connecting screw is freely accessible at the different distance planes of the installed wiring.

Abstract: A thermosetting coating composition containing an acid-curable amino resin and from 0,1 to 10 percent by weight of a blocked sulphonic acid, calculated on the weight of amino resin. The blocked acid used is an O-sulphonyl hydroxamic ester of the formula [RSO2ONHCOO]nA, wherein n represents an integer from 1 to 5 and R and A are organic groups. The new blocked acids are better soluble in the current solvents used in these coating compositions. The compositions may be used advantageously for coating a substrate by electrostatic spraying.

Date Jun. 28, 1990.Prereduced iron oxides are supplied to a smelting vessel (1) for the production of iron or steel by directing a hot reducing offgas from the vessel (1) into a vertical riser duct (8) without substantial cooling of the offgas and by way of inlet (16), particulate iron oxide containing material is entrained in the hot reducing offgas as the gas is conveyed upwardly through the duct (8). The hot gas heats the entrained material to a temperature at which partial reduction of the iron oxide occurs, the hot gas thereby, losing sensible heat. Additional materials may be introduced to the duct (8) for entrainment in the gas. Particulate material is separated in a cyclone (9) from the gas and the separated partially reduced material is introduced to the smelting vessel by way of passage (12). The particulate material, or part of it may be recycled by way of passage (15) through the vertical rise duct before the partially reduced material is introduced to the smelting vessel and only part of the hot reducing offgas emitted by the vessel may be directed into the duct.

Date Sep. 15, 1994A metal mould for making a frozen confectionery product is made of a titanium-containing materials, the mould being produced by cold-working a sheet-formed blank, either by deep-drawing or by pressing two half shells which are subsequently welded together. By using titanium for the ice lolly moulds, it is possible to avoid the use of poisonous inhibitors, without any risk of corrosion on the moulds. There is a considerable risk of corrosion on the moulds as the moulds used in the production of frozen confectionery products are subjected to freezing baths with strong saline solutions. When using titanium material for making the metal moulds, it is further possible to perform stress-relieving annealing at a lower temperature than was formerly possible when the moulds were made of stainless steel.

Abstract: A conically ported liquid ring pump has one or more port structures with cone angles in the range from 15 degrees to 75 degrees. These cone angles are substantially greater than previously used cone angles (most commonly about 8 degrees). The large cone angles of this invention give the fluid flowing between the cone and the rotor significant components of both radial and axial velocity. Large cone angles also allow the port structure(s) to be made axially shorter, which has a number of important advantages such as shortening the unsupported length of the rotor shaft. These attributes of the present pumps are helpful for such purposes as allowing the length-to-diameter ratios of the pumps to be economically increased. In addition, the pumps of this invention retain many of the desirable attributes of conically ported pumps. <IMAGE>
