Title: Case for storing elongate objects, in particular tools such as spiral drills
Inventor: PLATTE WILLI
IPC: B65D85/20
Filed: 1983-06-23
Abstract: The case for storing elongate objects, in particular tools such as spiral drills, screw taps and the like, consists of a bottom part (1) and a lid part which is connected pivotably thereto. The pivot bearing is formed by two coaxial pivot pins (4) which point towards one another, are connected to the case so as to be elastically expandable in relation to their mutual spacing and are inserted releasably in pivot bearings. A securing member which locks the mutual pivoting of the lid and bottom parts is arranged substantially opposite the pivot bearing. At least one of the pivot bearings has at least one projection which projects freely from the circumferential surface of the bearing into the clear receiving cross-section. Furthermore, the pivot pin (4) has an annular groove for receiving the projection or projections and cutouts, extending axially from the annular groove to the free end of the pivot pin (4), for the passage of the projection or projections. In this case, the mutual rotary position of the projections and the cutouts is selected such that the axial passage of the projections through the cutouts is only possible when the lid part and bottom part (1) are pivoted open. <IMAGE>

Patent DE-3328913-A1 (DE)
Title: Device for fastening a pipe in a bore
Inventor: HENRICY ERICH
IPC: F16L41/08
Filed: 1983-08-10
Abstract: The invention relates to the end fastening of a pipe in a bore which penetrates a wall and corresponds in diameter approximately to the outside diameter of the pipe. The pipe (3) bears with an annular bulge (10) against the pipe-side surface (6) of the wall (1). Arranged in the pipe is a hollow rivet (4) whose set rim (7) on the surface (5) of the wall on the side of the pipe end grips over the bore and whose rivet shank (8) terminates in the region of the annular bulge in the pipe. The outside diameter of the shank end (9) is widened in this case so that a pressurised sealing surface exists in each case between the shank end and the pipe bulge (10), on the one hand, and between the pipe bulge and the wall surface on the pipe side, on the other hand. The hollow rivet (4) is preferably a blind rivet without a filling pin, so that it can be deformed outwards from the set rim (7) using conventional riveting tools. In this case, the annular bulge (10) of the pipe is preferably formed in one operation when the shank end (9) is widened. The pipe fastening is exceptionally stable, in particular for small pipe wall thicknesses and small wall thicknesses, and also permanently withstands flexural and vibrational stresses in the pipe at the fastening point, such as occur chiefly with long pipes fastened at one end. Furthermore, it can be produced quickly and cost-effectively, ... Original abstract incomplete. <IMAGE>

Patent DE-3402117-A1 (DE)
Title: Pressure regulator
Inventor: BURKEL RAINER DIPL ING
IPC: G05D16/20
Filed: 1984-01-23
Abstract: A pressure regulator (11) has a soft-magnetic coil former (12) in whose recess (13) a coil (14) is arranged. The coil (14) is effectively connected to a permanent magnet (27) which is arranged on a non-magnetic control slide (24) which is guided in a sliding manner in a slide hole (16). The magnetic field which is produced when the coil (14) is energised is formed in the same polarity as the permanent magnet (27), so that the control slide (24) is moved away from the coil former (12) and hence into the control position. Since the coil former (12) consists of soft-magnetic material, the permanent magnet (27) is attracted when the coil (14) is not energised, and thus moves back to its defined original position. A copper layer (29) is arranged in a recess (28) in which the permanent magnet (27) is guided. Vibrations of the permanent magnet (27) are damped by eddy currents induced in said copper layer (29). The pressure regulator (11) is of simple and compact construction and has an approximately proportional relationship between the applied current and the desired pressure to be set. <IMAGE>

Patent DE-3408809-A1 (DE)
Title: Devices on a catheter to improve removal of conducting pathway stenoses
Inventor: SCHUBERT WERNER DR MED
IPC: A61M29/02
Filed: 1984-03-10
Abstract: Very severe stenoses contain only very narrow residual lumina. These residual lumina must also be entered by the balloon for direct attack from the inside. The nozzle body with the main nozzle and nozzles arranged in a circle around it for the balloon is placed between the narrowed, front part of the catheter and the thicker, longer, rear part of the catheter. The front, narrowed part of the catheter then carries the balloon on its own, or else an "actual front balloon" is used without the catheter shaft passing through it in the usual way. When the patient assumes an appropriate posture, a basic guidance and at the same time easier location within narrow stenoses are obtained by the use of a platinum chain which is particularly heavy due to the specific gravity, and this either loads the front of the "actual front balloon" right from the start or passes from proximally over the main nozzle of the catheter into the conducting pathway or residual lumen of the stenosis and further on. A three-way valve may be inserted behind the actual front balloon in order to produce a catheter. <IMAGE>

Title: Open-cast method of directly reloading several discs and special conveyor belt for carrying out the method
Inventor: FAUR GYOERGY
IPC: E21C47/04
Filed: 1984-03-14
Abstract: The invention relates to an open-cast method of directly reloading several discs in the winning of coal and other minerals as well as a special conveyor belt for carrying out the method. The essence of the method according to the invention consists in the fact that an inner stockpile is formed at the point of the lowermost mineral or coal seam worked, where the first overburden layer is directly reloaded by a belt-type stacker, the next overburden layer is loaded by the excavator onto a special conveyor belt with a movable discharge point and is transferred from the discharge point by a belt car onto the belt-type stacker, while the stockpile material of the further overburden layers is reloaded via belt cars and inclined conveyor bridges first onto the special conveyor belt and from there in the aforesaid manner onto the belt-type stacker. By means of deflection drums and tension-roller pairs, the special conveyor belt is provided with such a special belt guide that the endless conveyor belt transports the material from both ends into the centre to the discharge point movable along the special conveyor belt and designed as a tripper car, as a result of which the special conveyor belt can be simultaneously loaded from several discs.

Title: Device for supplying a three-phase insular network from a single-phase railway network via a railway converter
Inventor: BECK HANS-PETER DR ING
IPC: H02J3/00
Filed: 1984-03-22
Abstract: For a device for supplying a three-phase network from a single-phase railway network via a railway converter which consists of a single-phase synchronous machine, an asynchronous machine which is supplied in a duplicated manner, a direct converter and a three-phase shaft generator with an excitation device, and is used for energy exchange between the single-phase network and the three-phase network and, in the event of failure of the three-phase network, is intended to supply said network with electrical power from the railway network, the object exists for the case of failure of the supplying single-phase network of supplying the three-phase insular network which is still serviceable from the railway network until the defect has been remedied. This is achieved in that a converter with a DC output (8) is provided which is supplied from the single-phase network and whose output terminals (+, -) are connected to the rotor winding of the asynchronous machine (1) via a first switch (S91) and a second switch (S92), and which is used to excite this asynchronous machine (1), this asynchronous machine (1) being driven by the single-phase synchronous machine (2). <IMAGE>

Title: Tablet disintegration tester with automatic time measurement complying with the requirements of DAB, USP and other pharmacopoeias
Inventor: KOHLER BERNHARD
IPC: G01N33/15
Filed: 1984-04-10
Abstract: Measurement of the tablet disintegration time is an international requirement. Automatic time measurement in laboratories and production plants is to provide more accurate results of the six measurement cells with print-outs. In addition, the user can do other work, and disintegration need not be monitored. In this application the following principle was applied: tablets or such like test material are pressed onto the screen in the measurement cells by the standardised disc and the lifting movement. This slight pressure is transmitted to the outside. Loss-free magnetic lever transmissions actuate digital Hall IC. Once the test material in a measurement cell has disintegrated the disc cannot press the screen downwards. Lateral noses which at the same time determine the switching threshold prevent this. The measurement basket with the six cells is immediately operative after connection. Two-coloured light-emitting diodes in the electronic part are intended for setting of the switching threshold and the disintegration time. A computer is responsible for start and stop, picks up the signals of the measurement basket, prints out the disintegration times including the mean, and finally switches the lifting device off.

Title: Process for precipitating protein in milk and/or whey
Inventor: HERRMANN MARTIN PROF DR ING
IPC: A23J1/20
Filed: 1984-12-12
Abstract: The invention for the deproteination of milk (sweet or acid whey) and/or whey is based on process steps which include a demineralisation of the starting product. By means of these process steps, a destabilisation of the proteins is achieved, as a result of which these are denatured at an appropriate pH and with a heat treatment. These denatured proteins can preferably be obtained via a separation process, a deproteination occurring in relation to the degree of desalting. The protein content in the milk and/or whey can be reduced in this process to values around 0.2%. In addition, by partial or complete desalting of milk and/or whey or other foods, it is possible, in the case of acidification at the same pH to give an incompletely or completely desalted product, to achieve a lower acid content in the product. Of interest in this case, furthermore, is the reduced acidification time, in addition to the other advantages demonstrated.
