Abstract: A hard shell tamper-proof capsule having cylindrical, telescopically joinable, coaxial cap and body parts each having a side wall, an open end and a closed end, the cap and body being adapted to be mutually joined; characterized in that the body closed end has either a generally hemispheroidal, a pyramidical, a conical or a flat outside surface, and that the body side wall is totally enclosed within the cap side wall thereby exposing only the outside surface of the body closed end for gripping, which impedes separation of and tampering with the joined capsule.For additional security the tamper-proof capsule may be provided with locking means of circumferentially extending ridges or grooves.For further security the tamper-proof capsule may be provided with sealing means such as hot water, steam, or hot solutions or emulsions.

Abstract: A digital measuring instrument which samples at discrete points in time the analog input signals emitted by a measurement transducer of an electrical supply system in a sample and hold circuit. The sampled values are digitized in an analog/digital converter and are then used to determine a system specific quantity such as, for example, the root mean square value or the system frequency. This measuring instrument is suitable for solving the essential measurement value processing tasks occurring in an electrical supply system in a simple manner and with projectable measurement accuracy. This is achieved by the fact that the digital processing unit includes a block for shifting the fundamental and harmonic frequencies to a direct current signal which is proportional to the system specific quantity and a subsequent filter arrangement with a digital low-pass filter for suppressing the frequencies deviating from the direct current signal and a digital band-stop filter for suppressing aliasing frequencies.

Abstract: A triggering method for a thyristor switch which has at least two thyristors wired in series and a thyristor wired in antiparallel to each of these thyristors. The thyristor switch is triggered or cut off as a function of a specifiable on-off signal. At least a single triggering of a thyristor to be switched-on takes place at the earliest if a positive anode-cathode voltage is applied to it which exceeds a specifiable switch-on voltage limiting value. The method comprises generating a trigger standby signal if the on-off signal is in the switch-on condition and, with a specifiable minimum number of thyristors to be triggered wired in series, their anode-cathode voltage is greater than the specifiable switch-on voltage limiting value. At least a single triggering of each thyristor to be switched on takes place by means of a short-duration trigger pulse only during the duration of the trigger standby signal.

Abstract: Foam capsules with telescopically engaged body and cap portions, also known as hard shell capsules, having a special wall structure, obtained by a microdispersion of a gas in a gelatin solution.The capsule body and cap portions are formed by dipmolding the film-forming mixture obtained by a microdispersion of the gas in a gelatin solution; optionally with the inclusion of a plasticizer and/or coloring agent, and/or flavoring agent, and/or foam stabilizer, and/or gelatin extender.By a suitable choice of the gas proportion in the capsule wall and its micronization level, it is possible, within certain limits, to control the capsule wall disintegration speed and its opacity. In addition, inclusion of gas bubbles into the capsule wall lowers the gelatin content for a foam capsule and provides energy saving during the process due to a faster drying of the wall, thereby providing lower cost prices for the production of pharmaceutically acceptable capsules.
