Patent DE-4019810-A1 (DE)
Title: Detection of AC or DC in relatively compact device - stimulating high permeability core with HF current with magnetic field shifting hysteresis curve coercivity range
Inventor: SHOJI KATSUYAMA
IPC: G01R19/15
Filed: 1990-06-21
Abstract: A.c. or d.c. is detected using a high permeability iron core (1a) with rectangular hysteresis curve and a stimulation coil (7) supplied (9) with HF current via a circuit connected to a detection resistance (8). The core is stimulated under identical conditions in the positive and negative regions and magnetised above the hysteresis curve coercitivity force range. - This range is displaced to change the stimulation current in reaction to applying a magnetic field. A resulting difference in the positive and negative voltages yields the measurement current value.

Patent DE-4091995-A1 (DE)
Title: Automatic extrusion-blow moulding plant
IPC: B29C48/475
Filed: 1990-10-27
Abstract: Hollow thermoplastic articles are produced by extrusion-blow moulding. Batches of parisons are produced from a continuously operating extruder which has at least one chamber to store the material and a reciprocating device to empty that chamber; the extruder action has two phases, whereby the chamber is at least partially filled in the one and is moved to the outlet of the extruder head in the other where it is expelled to form a parison; The volume of expelled material consists of the part held in the chamber and a part which is fed into the extruder head from the extruder(s) used, and at least one oart is exoanded under pressure in the blow mould of at least two tools and is then cooled. During at least a part of the (mould) filling stage the movement and/or speed of the device to empty the chamber is recorded by a central control unit and compare with nominal values; in the event of any set deviation at least one extruding parameter (e.g. shot volume, stroke of drive to empty the chamber, speed of expulsion from at least one chamber, extruder power etc.) is changed so that the preform from the extruder head is produced in the required vol. to the closest possible accuracy.

Title: Cannula for implanting identification carrier in animal - has carrier placed into intended location  by mandril displaceably fitted in cannula and forming once-only usage with it
Inventor: HIRSCH CHRISTIAN DIPL ING
IPC: G01S13/74
Filed: 1991-03-06
Abstract: The cannula can be of steel, plastic or other suitable material, and has an inclined ground point. It is fitted in a holder which incorporates a releasable cap for placing around it. At a distance from its holder and point, the cannula has a lumen constriction, and the cross-section in the region of this formation is less than the dia. of the identification carrier, thus ensuring that the carrier cannot slip over the constriction in the direction of the holder. In the cannula is a mandril displaceable from the cannula holder side. This mandril has in the end area turned away from the cannula holder side a reinforced cross-section as an all-round convolution, the dia. of which is greater than that of the constriction. In order to deposit the identification carrier in a tissue, a pin element works on the mandril which has a dia. smaller than that of the volume of the cannula so that by drawing the pin backwards the mandril pauses in its position, whereby the identification carrier reaches the tissue. ADVANTAGE - For the implanting of transponders in animals
Patent DE-4112091-A1 (DE)
Inventor: HELLER GUENTHER DR ING
IPC: G01G13/06
Filed: 1991-04-12
Abstract: In a process for checking the quantity of at least one liquid flowing through a flexible hose, the quantity of liquid flowing through the hose is determined as an actual value, the actual value obtained is compared with a predetermined desired value and the through-flow cross-section of the hose is kept constant or varied in dependence on the difference between the actual value and desired value. In particular, the through-flow cross-section of the hose is varied in steps, and in order to reduce the cross-section the hose can be pressed linearly against a countersurface by means of a pinching element. The process is designed in a particular way especially for the weighing of liquids. In addition, a device for carrying out the described process for the weighing of liquids is claimed.
