Title: Method for the promotion of nucleation in the cooling of metallic melts, in particular steel melts
Inventor: KUBON ACHIM
IPC: B22D11/115
Filed: 1981-07-16
Abstract: The method for the promotion of nucleation operates on the cavitation principle. To produce a fine-grained (globular) solidified structure, to avoid segregation, to assist the separating out of inclusions, to prevent shrinkage cavities and improve the feeding behaviour by means of a globular structure and the general improvement in the casting technology, for example to increase the quality of casting and output in continuous casting, it is proposed to assist cavitation by the use of electromagnetic rotating, travelling or alternating fields with a frequency of from 15 to 30 kHz. The electromagnetic field (current density, voltage, time of action) is set as a function of the viscosity of the melt (analysis, overheating). In addition, it is possible, to further assist cavitation phenomena, simultaneously to feed inert gas in the form of bubbles into the melt.

Abstract: The invention relates to a bulk-materials conveyor with a conveyor frame and conveyor belt. The conveyor belt is driven and is guided on support rollers as well as over deflection drums of the conveyor frame. On its underside, the conveyor belt has a longitudinal web in the region of its centre. Said web is connected at least non-positively to the conveyor belt.

Title: Relay with a bridge contact arrangement and method for its production
Inventor: HUEBNER WOLFGANG
IPC: H01H1/26
Filed: 1982-01-27
Abstract: In a bridge contact arrangement, the two mating contact springs (10, 11) are embedded in a plane in an insulating material support (12) which is mounted in a groove in the base body (1) by means of a force fit. The plane of the mating contact springs (10, 11) is at right angles to the base plane of the base body (1) so that connecting tabs of both mating contact springs (10, 11) can be led out parallel to one another optionally downwards through the bottom of the base body (1) or in an extension of the mating contact springs. This results in the capability to provide the relay with a bridge contact arrangement for two different installation positions without any structural change. <IMAGE>

Abstract: The invention relates to a high-voltage wire-insertion bell which creates more favourable production conditions and, in particular, favourable assembly conditions and at the same time completely complies with the requirements for dielectric strength and life. The insulating body (32) surrounds the cavity whose longitudinal axis runs parallel to that of the current conductor (31) and whose air-space is divided into two parts by a separating wall at right angles to the longitudinal axis. According to the invention, the insulating body (32) has two or more walls along at least two mutually opposite jacket sections of the passage cavity, the outer wall (34) enclosing at least one inner wall (35), and is formed from two half-bodies (32a, 32b) which match one another along joint faces (36a, 36b, 37a, 37b). The joint faces (36a, 36b) constructed in the outer wall (34) are displaced along the circumference of the walls with respect to the joint faces (37a, 37b) constructed in the inner wall (35). The separating wall is formed by a plurality of wall parts which are arranged outside the outer wall (34), between the walls and inside the inner wall (35), the two respective adjacent parts being displaced with respect to one another along the longitudinal axis of the cavity. <IMAGE>

Said ring consists of an elastic sealing material, especially silicone, and on each of its two sides facing the glass plates (6) has at least two beads (collars) spaced radially. The glass plates (6) are supported rigidly with respect to the solid electrodes (4). Accommodated between the solid electrodes (4) there are spacer rings (5) made of a nondeformable plastic, pins (15) passing through the spacer rings (5) in an axially parallel manner and penetrating, with their pointed ends, the electrode surfaces. <IMAGE>

IPC: H05B3/32
Filed: 1983-01-05
Abstract: In an electrical resistance or heating grid having a current-free edge and, in the unobstructed space of the same, electrical current conductors which are arranged such that they run to and fro and whose sections lying side-by-side are held by means of insulating material elements, the problem exists of easy production of individual items or small batches for special applications without any special cost for equipping, for example, a Jacquard loom. In order to achieve the object of creating such a grid which can be individually designed and constructed without increased cost and which at the same time is quick and simple to produce, the electrical current conductor (16), which is provided with a restoring force by means of design measures, for example coiling, is held in a clamped manner such that it fills the surface by means of insulating material elements (clamping elements 18) which are arranged offset and connect in each case at least two current conductor points in an insulated manner. The insulating material elements (18) preferably have a bracket-shaped design with two profiles for retaining and holding two current conductor points in an isolated support in an insulated manner, for example by means of an isolating web (20) or an adequate spacing. <IMAGE>
