Title: Method and apparatus for removing deposits on lances which can be moved relative to a metallurgical vessel
Inventor: KOOPMANN HERBERT ING GRAD
IPC: F27D25/00
Filed: 1981-02-20
Abstract: The invention relates to a method and apparatus for removing deposits on lances which can be moved relative to a metallurgical vessel and have exchangeable sections, in particular probe lances equipped with measuring or sampling probes. During measurement or sampling operations for monitoring metallurgical processes, deposits are formed on the connecting section of the lance and these can prevent the connection of probes or lead to damage. In order to allow satisfactory coupling of exchangeable lance sections with as little outlay as possible, a plurality of stripping edges are brought to bear temporarily on the lance during its removal from the vessel, these edges being provided with additional support perpendicularly to their direction of motion, at least during the stripping operation. The deposit removal device according to the invention has a supporting body (15) arranged outside the vessel (14) and a plurality of blades (20) and guide rollers (19) situated above the latter which are supported on the supporting body (15) and, in a working position, rest against the lance (1). <IMAGE>

Title: Endless magnetic-tape cassette for high tape speeds
Inventor: MANGOLD HANS DIPL ING
IPC: G11B23/06
Filed: 1981-03-20
Abstract: A description is given of an endless magnetic-tape cassette for high tape speeds which avoids the disadvantages of known systems and makes it possible to increase the operational reliability with a greater amount of tape and higher tape speed. This is achieved according to the invention as shown in Fig. 1 by an outer tape roll being wound separately from an inner tape roll through at least 360 DEG  a certain distance away on a slideway. The outer tape roll, preferably comprising a single winding, has in this case a certain coefficient of friction with respect to the magnetic tape, dependent on the coefficient of friction within the inner tape roll. Furthermore, in the interior space of the inner tape roll there are skid-shaped guide elements, which virtually fill the interior space and, together with the winding reels around which the inner tape roll is guided, give the latter a substantially eliptical form. Such an endless magnetic-tape cassette is suitable in particular also for video machines with longitudinal track recording. <IMAGE>

Title: Transfer arrangement for a rack-loading appliance
Inventor: STAGGL ROLAND ING GRAD
IPC: B66F9/07
Filed: 1981-04-16
Abstract: Rack-loading appliances have hitherto been transferred by transverse displacement from one rack aisle into another by means of displacing bridges. There is an overturning risk here if the rack-loading appliance is narrow in relation to the height. In the novel transfer arrangement the rack-loading appliance (6) travels out of the rack aisle (2) onto a turning rail (13) which is arranged in the transfer aisle (5) and is turned about a perpendicular axis (12) for moving the rack-loading appliance (6) along the rack aisle (5). The rack-loading appliance (6) travels over further turning rails (13) up to the desired rack aisle (2), where it is again turned for entry into the latter. The turning rail (13) is driven by the travel motor of the rack-loading appliance (6) by means of a pressure-transfer roller (17) mounted thereon, which in the area of the turning rail (13) interacts with a fixed pressure-transfer rail (16) like a connecting-link guide. When the rack-loading appliance (6) crosses the turning rail (13), the pressure-transfer roller (17) passes into an angled area (16b) of the pressure-transfer rail (16) and in the process exerts a lateral pressure on the rack-loading appliance (6), which as a result is turned with the turning rail (13). The rack-loading appliance (6) continues to travel on the turning rail (13) even during the turning. <IMAGE>

Title: Method for processing ultrasonic echo signals from different irradiation directions, in particular for ultrasonic image processing in the field of material and fabric examinations
Inventor: MADERLECHNER GERD DIPL PHYS
IPC: G01S7/52
Filed: 1981-06-23
Abstract: Image faults (artefacts) in ultrasonic echo signal formers arise, inter alia, as a result of interference signals which are randomly distributed and occur, for example, in the form of oscillation processes which arise during filter processes. In order to be able largely to suppress these image faults, a plurality of sub-images (T1, T2...Tn) with different sensing parameters are produced in each case from a main sensing direction, which sensing parameters are ultimately superimposed to form a combination image (K). The interference portions are largely averaged out and the useful portions are even amplified. <IMAGE>

Patent DE-3235430-A1 (DE)
Title: Bragg cell
Inventor: STOCKMANN MICHAEL DIPL PHYS
IPC: G02F1/125
Filed: 1982-09-24
Abstract: A Bragg cell (BZ1) consisting of a planar waveguide (BW1) and a device (W) for generating a lattice structure (GS) in the waveguide (BW1) for the purpose of beam deflection is described, in which a refracting interface (BF1) is arranged in the beam paths of the radiation (AS) diffracted by the lattice structure (GS) and the non-diffracted radiation (US) in an oblique fashion such that the diffracted radiation (AS) is totally reflected at this refracting interface (BF1), while the non-diffracted radiation (US) can emerge from the interface (BF1). As an alternative to this, the interface can also be arranged such that the non-diffracted radiation is totally reflected at the interface, while the diffracted radiation can emerge from it. Instead of the refracting interface, it is also possible to generate in the beam paths a further lattice structure in a waveguide, which has the effect that the two radiations are deflected even further from one another. <IMAGE>
