Patent DE-3000860-A1 (DE)
Title: Leak testing of drinks bottles before filling - by computer controlled combined test and removal using regulated vacuum
Inventor: MASSOTT MICHAEL NECKARGEMUEND
IPC: G01N33/00
Filed: 1980-01-11
Abstract: The method is for leak testing drink bottles before they are filled and eliminates damage to filling mechanisms, loss of beverage, and consumer claims for loss of contents or lack of carbon dioxide. It is compatible with the high rates of bottle movement required in a bottling plant. The method involves testing for leaks by vacuum. The bottles without leaks are lifted up by vacuum whilst those with leaks are left behind and rejected by a deflector. The degree of vacuum is regulated so that damage not severe enough to cause liquid leakage or loss of carbon dioxide does not cause rejecting. The leakage potential can be tested by reproducing sealing. A microcomputer can be used for automatic control of the plant.

Title: Rubber sealing ring deformation measurement - using interchangeable cylindrical jaws with sliding or roller guide to measure deformation arising from radial force
Inventor: SCHWENKSCHUSTER HANS
IPC: G01B5/30
Filed: 1980-03-13
Abstract: A device measuring rubber sealing ring washer deformation after application of a radial force of a given magnitude has moving and fixed holders each with an interchangeable cylindrical measurement clamp jaw. The jaws are clamped together with between them a spring element and a distance measurement device. The measurement accuracy is higher than that of similar devices and independent of the measurement jaw configuration. No readjustment is therefore necessary when the jaws are changed. A guide in the moving holder ensures that the opposing jaw faces are absolutely parallel in all positions. The guide arrangement may consist of sliding or roller guide devices. If two equal length hinge supports are used they have a separation distance in the movement direction at least equal to their length.

Title: Damping ratio equalising circuit for two wire speech transmission - uses compressor amplifier and speech recognition circuit for each direction
Inventor: BRUECKNER EGON DIPL PHYS
IPC: H04M3/54
Filed: 1980-12-10
Abstract: The two wire speech transmission system using compression and expansion, uses a two way return, so that the required counter speech can take place. At a junction point, each line incorporates a compressor/amplifier (KVI, II) for the two directions. These are controlled by a number (ST) such as an A/D converter, with inputs connected to a speech recognition circuit (SPI, II) for each direction, so as to obtain the required damping for all frequencies. The sum of both amounts of amplification does not exceed logarithmically twice the min. value of the damping for the junction. The transmission ratio of an amplifier in one direction matches the amplitude of its input level, and the transmission ratio of the other amplifier is adjusted according to a given formula.

Title: Method for the regeneration of a melting crucible
Inventor: DREWS KLAUS
IPC: B22D41/00
Filed: 1981-03-18
Abstract: Melting crucibles which have become brittle, particularly those made of iridium, which after a few heating and cooling cycles with molten metal have a coarsely crystalline brittle structure and are hence of no further use, are melted in certain areas over virtually the entire surface by the formation of melting zones, by means, for example, of a welding torch. The resulting structure in the material of the crucible is so ductile that it can accommodate the work hardening associated with a mechanical remachining process (sizing). <IMAGE>

Patent DE-3113809-A1 (DE)
Title: Anti-theft packaging, in particular for audio cassettes
Inventor: KAIN ANTON
IPC: B65D73/00
Filed: 1981-04-06
Abstract: An anti-theft packaging has a container (1), formed on a large backing sheet (2), with counter catch members (8) which are arranged inside the container (1) and on which catch members (11) of a lid part (4), which can be fitted on enclosing an audio cassette (3) or the like, engage captively so that non-destructive removal of the lid part (4) is no longer possible. In order to facilitate the destructive removal of the lid part (4), intended tearing lines (20, 21) are provided in the lid part to produce separate sections (4', 4'') of the lid part (4), and the catch members (11) are held on the counter catch members (8) so as to be displaceable in the direction of the intended tearing lines (20, 21) so that, by means of such a displacement movement, the snap-on catch connection can be produced between the individual sections (4', 4'') of the lid part (4), and the catch members (11) are held on the counter catch members (8) so as to be displaceable in the direction of the intended tearing lines (20, 21) so that, by means of such a displacement movement, the snap-on catch connection between the individual sections (4', 4'') of the lid part (4) can be released on the counter catch members (8) and the latter can be disengaged and removed by displacement. By means of tearing handles (23) of suitable shaping, the tearing of the lid part (4) at the intended tearing lines (20, 21) with or without tools can be facilitated. The subsequent displacement can in any case simply take place by hand. Nevertheless, the security against theft is ensured since, even the tearing along the intended tearing lines (20, 21) is noisy due to tearing the hard plastic and the displacement back and forth of sections (4', 4'') of the lid part (4) cannot only be carried out with a simple, fast manipulation and, moreover, can be made slightly more difficult in terms of construction if required. <IMAGE>

Title: Pneumatic-hydraulic energy converter
Inventor: WILLIG KURT
IPC: F04C2/356
Filed: 1981-09-16
Abstract: The main problem of a hydraulic vane-type rotary motor with as many discs as it needs for the displacement of oil in the swept volume, if it is to be used primarily in an energy converter is still the movement of the vanes into the swept volume, since the vanes are also under pressure from below. In addition, the centrifugal force of the vanes also has an effect but this can now be counteracted by correspondingly large and heavy counterweights on the rocker levers. This hydraulic motor is intended to make an energy converter feasible since only very little leakage oil has to be pumped back into the pressure vessel. Even if the leakage oil foams in contact with air, such small quantities can be settled that it defoams before it is pumped back. One genuine advance is certainly the arrangement of magnets for pressing the vanes into the swept volume and where necessary the division of their work with the cam lift into the sphere of influence of the magnets.

Title: Agent in the form of granules based on polysaccharide gums, process for the preparation thereof and use
Inventor: NITTNER ERICH DR
IPC: A23P10/25
Filed: 1981-10-08
Abstract: Agents in the form of granules based on polysaccharide gums, which, relatively to the dry matter, contain 40 to 90% by weight of at least one physiologically tolerated polysaccharide gum swellable in water, such as for example guar gum or pectin, and at least 10% by weight of physiologically tolerated fats or fatty substances having a melting point of 25 to 40 DEG , such as for example cocoa butter or palm kernel fat, are suitable, from the dietetic/therapeutic aspect, for levelling out the post-prandial blood-glucose and serum-insulin concentrations. These agents further produce an increase in the gastrointestinal tone, prevent digestive upsets and reduce elevated cholesterol levels. They can easily be suspended in water at room temperature and are easy to take. In the stomach, under the influence of body temperature, they quickly swell and develop a high viscosity. For the preparation, the individual components are incorporated together and the mass obtained is granulated.
