Abstract: A regulator having turbulence generating device for controlling thrust. A differential piston (2) is biased by a spring (3) located in a discharge channel (8a) of a medium under pressure. The spring (3) is weighted in such a way that it is compressed at a given pressure within the container so that the differential piston (2) takes a first end position and decreases the opening of the discharge channel (8a) to a minimum. The spring (3) expands proportionally to the pressure drop due to the discharge of the medium (18) from the container and shifts the piston (2) so that the opening of the discharge channel (8a) increases gradually until the piston (2) has reached a second end position as soon as a given minimum pressure has been reached in the container.

Abstract: The invention concerns a tamper proof closure for a threaded mouth. The closure comprises a plastic cap provided by means of tear-off elements with a ring. If when the mouth is sealed the ring is still on the cap, then it displays the fact it was not opened yet. The ring is secured against a screwing-off motion by lock elements at the mouth. The ring is provided with at least one aperture entered by a catch on the cap. When the cap is rotated off, the catch destroys the ring. This can be facilitated by providing predetermined rupture sites in the shape of narrow connection strips between certain ring parts.

Abstract: The application describes an automatic focusing system for photographic cameras. The system functions by means of an infrared light source and an infrared detector. The infrared radiation is focused as a function of object distance in such a manner on the detector that this detector is divided into two detector segments each of which supplies a partial current of which the ratio depends directly on the object distance. The detector is followed by an electronic computing circuit which sets the objective as a function of a preselection implemented by a switch to one of the following modes of operation:(a) the focus is on the object to be photographed(b) the depth of field is extended from the object toward the camera(c) the depth of field is extended from the object to the rear(d) the depth of field is extended from the object to infinity(e) the depth of field is extended to between two consecutively targeted objects.

Abstract: A pitched cable is sheathed over a defined length with a plastic polyamide film. The method includes the steps of slipping a plastic polyamide tube over a pitched cable and affixing this tube to the cable by hammering. An additional procedural step is also described, namely the prior reduction of the outside diameter of the pitched cable, so that with appropriate dimensions of the plastic tube, it is possible to make a plastic sheathing for the pitched cable, with the outside diameter of the plastic tube then being only trivially larger than the outside diameter of the unsheathed cable length.

Abstract: In a pumping apparatus having a flexible diaphragm a disc is arranged for supporting the diaphragm. The support disc has holes through which the pump liquid passes. For preventing the diaphragm from being drawn into the holes plugs are inserted in the holes in such a way that openings or slots are formed which are sufficiently wide for the liquid to flow therethrough but are not wide enough for the diaphragm to be sucked into the support disc. The diaphragm is thus prevented from becoming damaged. Various embodiments of suitable plugs are illustrated which either form the narrow openings in combination with the surrounding wall of the holes in the support disc or are provided with holes or slots in the plug body.
