Title: Process for fabricating a Josephson circuit employing Josephson tunnel elements
Inventor: DAALMANS GABRIEL M DIPL ING
IPC: H01L39/24
Filed: 1981-07-22
Abstract: A process for fabricating a Josephson circuit employs Josephson tunnel elements which each contain, on a substrate body, superconducting layers, overlapping in a predetermined manner, of their base and counter electrodes consisting of a material having a very low voltage relaxation and a transition temperature which is at least as high as that of niobium, and between these layers contain a layer serving as a tunnelling barrier. Electrode layers are vapour-deposited in the holes of hole masks having hole patterns adapted to the geometric shapes of the layers of the tunnel elements to be generated. In addition, conductors for linking the Josephson tunnel elements to the circuit are formed, as well as control wires. The object of the invention is to be able to fabricate, in a simple manner, highly integrated circuits employing Josephson tunnel elements, with relatively low leakage currents. To this end, the invention provides that there is applied to the substrate body (5) a single hole mask (4) which consists of a high-vacuum-proof, thermally stressable material having a predetermined hole pattern (13) and which permits vapour deposition both of the layers (17, 18) of the base electrodes and of the layers (24, 25) of the counter electrodes at a vapour deposition angle ( alpha  or 180- alpha , respectively) predetermined in each case, and that the layers (17, 24; 18, 25) are then vapour-deposited under continuous vacuum conditions. <IMAGE>

Filed: 1981-10-28
Abstract: Membrane oxygenator which achieves a high degree of efficiency of gas exchange and is easily controlled in order to achieve the required extent of gas exchange. Stirring means located inside a housing in which a multitude of capillary tubes are arranged are employed for forcing the gas to increase the gas exchange. Pressure control means for setting the gas pressure inside the housing are employed for easy control of the degree of efficiency of the gas exchange. The pressure control means are mounted in the vicinity of an outlet orifice in the housing. Temperature control means are provided inside the housing for simultaneously carrying out the gas exchange and the temperature control in the oxygenator. The three novel means can be used in combinations in the same oxygenator.

Patent DE-3205540-A1 (DE)
Title: Cement adhesive holder
Inventor: STRAHL GERHARD
IPC: F16B47/00
Filed: 1982-02-17
Abstract: The adhesive holder has a cable attachment clamp consists of a plastic, metal piece. It is constructed as a hollow body, its hollow side facing the wall is terminated by an open grid surface which is connected firmly to the clamp body. The cable, or a plurality of cables, is simply pressed into the V-shaped open clamp, while steps which are constructed as barbs fix the cable in the clamp opening without further attachment. The cable attachment clamp can be constructed for a plurality of different cable cross-sections, by means of corresponding steps in the clamp opening. The adhesive holders can also be attached by untrained personnel, without machines, tools, screws or dowels, while, on the other hand, they allow specialist trained personnel to fit the adhesive holders more quickly than can be achieved with normal wall holders and operating methods. When using quick-setting cement for concrete walls, covers, cement plaster surfaces, stone walls, pumice walls, and ceramic tiles, a large number of adhesive holders can be fitted in a short time as wall hooks, shelf holders or cable attachment clamps. <IMAGE>

Title: Fume cabinet with ventilation curtain and air extractor
Inventor: HILBERS HEINRICH ING GRAD
IPC: B08B15/02
Filed: 1982-02-17
Abstract: Fume cabinets serve to contain the noxious substances in the exhaust air in a chemical laboratory. In order to be able to lead away exhaust air containing noxious substances without adversely affecting the operator, an intensive ventilation of the cabinet must be provided. The invention relates essentially to the fact that the working openings at the front side and the side faces of the cabinet are not blocked. A particularly upwardly directed air curtain, starting from the table edge, shields the opened face. The upper nozzle baffle device supports the curtain and is adjustable. Heavy noxious gases at the floor of the laboratory space are extracted by means of an extractor mounted below the table with injector action. Simultaneously, extraction is performed on the lower cabinet. The fume cabinet described above has a ceramic acid-proof rear wall in addition to the ceramic table plate. The function of the fume cabinet with ventilation curtain and air extractor is illustrated in Figures 1-4 of the enclosed drawing. The fume cabinet serves to save energy. <IMAGE>

Title: Lining element for furnaces
Inventor: SCHNEIDER HANS GERD
IPC: F27D1/12
Filed: 1982-07-07
Abstract: A lining element for furnaces is proposed which permits waste heat losses to be reduced. A lining element according to the invention has a flat trough-shaped housing which can be closed with a lid, furthermore a liquid duct laid in the housing with inlet and outlet connections which are each taken through the lid, and an insulating material to fill the interspaces between the housing and the liquid duct. The proposed lining element is intended to be fitted as the outermost wall on a furnace, namely the furnace vault. For this purpose, numerous such lining elements are arranged mutually adjacent and are connected together with their liquid ducts. The lining elements provide an additional insulation, with the result that a given furnace temperature is more quickly reached and fuel is saved. Waste heat which is released can now be used elsewhere, energy being thereby recovered. A certain quantity of heat can also be withdrawn from the furnace by means of the lining elements and thus the temperature in the furnace can be influenced. The liquid ducts can in particular be placed in a meandering shape and also in several layers in the housing. Sand, especially quartz sand, is appropriate as the insulating material.

Title: Two-stage process for the preparation of furfurol and glucose from cellulose-containing materials by acid hydrolysis
Inventor: KNAUTH HANS DIPL ING
IPC: C13K1/02
Filed: 1983-04-07
Abstract: To date, furfurol has been obtained by the action of dilute acid on pentosan-containing raw materials at temperatures above 160 DEG C. The cellulose has to date been hydrolysed either with dilute acid at high temperatures or with concentrated acid at low temperatures. High temperatures and pressures cause extensive wear, and dilute acids mean low sugar concentrations and high energy consumption. The process according to the invention makes use of the advantages of the different processes and excludes their disadvantages. This is brought about by the originally used dilute acid being concentrated by drying during the treatment.
