Patent IT-BO20020009-D0 (IT)
Inventor: CALDANA MARCUS
IPC: C09J5/00
Filed: 2002-01-10
Abstract: The annular workpiece (P) to be machined is positioned by one of its bases and with axial alignment onto a cylindrical base structure (1) onto which the workpiece remains secured due to the presence of a suitable adhesive (2) which for example has been previously distributed onto the said base structure. After the setting of the adhesive, the workpiece to be machined is loaded onto the machine tool, so as to be clamped by the chuck of this latter through the base structure (1) which carries it, and no more directly as in the known art. The clamping forces of the chuck are thus discharged onto the base structure (1) and they do not deform at all the workpiece (P) which can be machined with high precision and quickly, both on its inner and outer surfaces and, if required, also on its free base. Upon completion of the machining operation, the workpiece is unloaded from the machine tool and is separated by the base structure by means of a simple and quick mechanical or chemical-physical operation, which neutralizes the action of the adhesive employed.

Title: Welding socket
Inventor: KELLER HANS
IPC: F16L47/02
Filed: 1982-07-16
Granted: 1987-06-11
Abstract: A welding sleeve for connecting pipes formed of thermoplastic material includes an electrical conductor in the form of an electrical resistance wire. The resistance wire extends around the sleeve and has a pair of opposite ends for conveying current through the wire. The opposite ends of the wires can be connected directly to a source of electrical current, for instance a 220 DEG  V DIFFERENCE line. It is not necessary to provide transformers or timing relays. A melting material is incorporated into the conductor between its ends and it melts through when the energy necessary for welding the sleeve has been developed. After the current is supplied through the resistance wire, the welding process is completed when the predetermined melting material melts through. Such sleeves can be manufactured in a mass production operation, and the sleeves are much safer than the conventional devices used to-date.

Title: Non-oriented electrical steel sheet having a low watt loss and a high magnetic flux density and a process for producing the same
Inventor: MIYOSHI KUNISUKE
IPC: H01F1/16
Filed: 1983-01-26
Granted: 1986-02-20
Abstract: In the production of non-oriented electrical steel sheets, it has been attempted to decrese the watt loss, e.g. by adding Sn into silicon steels, but in such a case the relationship between the watt loss and magnetic flux density falls within the curves 1 and 1 min in Fig. 1. The addition of boron is therefore unsatisfactory for meeting the recent demands, for improving the magnetic properties of a non-oriented electrical steel sheet over those indicated by the curve 3. In the present invention, the combined addition Sn with B and/or sol. Al results in development of (110) and (100) textures which are desirable for the magnetic properties. A non-oriented electrical steel sheet according to the present invention, contains 0.015% of C at the highest, from 0.3 to 2.0% of Si, from 0.005 to 0.10% of sol. Al, from 0.02% to 0.20% of Sn, 0.007% of N at the highest, and 0.005% of B at the highest, the weight ratio of B content/N content being from 0.5 to 1.5, said non-oriented electrical sheet being produced by a process comprising an annealing of a hot-rolled steel strip. Instead of B, an appreciable amount of sol. Al may be contained in said sheet, when Mn content is from more than 1.0% to 1.5%.

Patent DE-3381095-D1 (DE)
Inventor: SCHMALL KARL-HEINZ
IPC: G01B7/02
Filed: 1983-05-06
Granted: 1990-02-15
Abstract: The invention includes a measuring arrangement and an inductive sensor arrangement with a transmitter coil which is fed by an RF oscillator, and a receiver coil in which an alternating field is induced by the transmitter coil. Transmitter coil and/or receiver coil are subdivided into at least two part-windings which are connected in opposition to one another in such a manner that the induced part-voltages at least partially cancel. The part-windings are arranged with respect to a metallic object in such a manner that when the position changes in at least one direction, the relative position of each individual part-winding with respect to the object changes differently. This results in a different influence on the inductances of the two part-windings with corresponding change in phase angle and output voltage. The relative distance of each part-winding from the object is monitored by means of auxiliary sensors. If the respective distances deviate, the auxiliary sensors produce a compensation signal by means of which errors due to an inclined position of the object or offset object edges can be avoided. <IMAGE>

Title: Process and continuous oven for the thermal treatment of cylindrical objects, especially tubes, preferably made of ceramic material
Inventor: VERHEYDEN GERARDUS M C
IPC: F27B9/24
Filed: 1984-07-17
Granted: 1987-08-27
Abstract: The invention relates to a process and to an installation for the heat treatment of cylindrical bodies, in particular pipes, of ceramic material. During the treatment, the pipes are dried, heated and sintered, and subsequently cooled, in successively arranged chambers. During transportation through the drying zone, the heating zone and the cooling zone, as well as in heat treatment during sintering, the objects are turned about their own axis independently of the transportation rate, so that they are not only evenly heated, but a possible deformation is also prevented. This type of transportation and heating with possible heat exchange between the individual zones makes possible a rapid heating-up without detriment to the cylindrical bodies, and thus a short design length of the installation. Above all, the sintering zone, which must consist of high-value, ceramic material due to the high temperatures, can be kept very small.

Title: Aerobic microbiological method
Inventor: CEDERBERG NILS ERIK ANDERS
IPC: C12N11/00
Filed: 1984-10-18
Granted: 1988-04-07
Abstract: An aerobic microbiological method in which a microorganism (2) is immobilized in a fluid-permeable fiber matrix (1) and supplied with a substrate solution (6) and an oxygen-containing gas (10) which are supplied to and leave the matrix as separate flows mutually at an angle of at least 10<o> and are brought into cross-flow contact with each other and with the microorganism (2) within the matrix (1). The fiber matrix preferably consists of mineral wool. The microorganism is immobilized in the matrix by being introduced in a, preferably conically, precompressed matrix which after introduction of the microorganism is further compressed to fix the microorganism in the matrix. Additionally, it is preferred to adjust the volume of the matrix during the course of the microbiological method in dependence upon the growth of the microorganism. This adjustment may be effected such that the pressure drop of the air flow (10) when passing through the matrix (1) is maintained constant.
Patent DE-3470197-D1 (DE)
Title: Guiding device
Inventor: KOBER HANS-RUDOLF DIPL ING
IPC: B23Q1/58
Filed: 1984-08-28
Granted: 1988-05-05
Abstract: The disclosed guide device utilizes no rigidly mounted external guide elements. However, a guide element freely slidable on an air cushion on a flat base can be lowered from the interior of a slide element (by removal of the air cushion) onto the base. Once the guide element has been lowered, it is fixed by subpressure onto the base and takes over the function of a rigidly mounted guide. The guide element, which was previously freely slidable on the base, is now exactly positionable along the guide of the guided element. If the displacement path is to be increased, then the slide piece element is fixed by subpressure on the base, the guide element is again acted upon with compressed air and driven within the slide piece in a displacement direction and at the end of the interior space is again fixed to the base. Now the slide piece is again released and can on its air cushion be further positioned exactly in the displacement direction. This stepwise movement is limited only by the size of the base.
