Patent number: 10986806Abstract: Milking clusters for a milking installation have four teat cups, each teat cup having a cup housing and a teat cup liner with a top region and a suction region. A connection for a milk tube is arranged at the cup bottom or at the end of the suction region of the teat cup liner. A mouth portion of a sterile air pressure line is arranged in the top region of the teat cup liner, through which pressure line sterile air is introduced at a volumetric flow rate greater than a fluid aspiration volumetric flow rate at the milk tube, such that a sterile air blanket is established in the top region of the teat cup liner. The milking clusters with the cup liner and sterile air blanket prevent milked milk from being contaminated by contaminants and microorganisms from the shed air, extending storage life for untreated raw milk.Type: GrantFiled: September 6, 2016Date of Patent: April 27, 2021Inventor: Friedrich Fischer

Patent number: 6158725Abstract: The device serves for storing energy. A spatial work range is defined by a displacement path upon compression of at least one spring of the spring storage. Along the work range in the working direction, at least two springs are arranged which are impinged in temporal succession upon compression and relaxation, respectively. For impinging the springs, at least one stationary retaining element and a mobile runner are provided. A spring loaded at a first point of time is immobilized in such a way that during a further displacement of the runner no further force is exerted by this spring between runner and retaining element. Reactivation of the immobilized springs is provided in temporal succession upon a reverse movement of the runner.Type: GrantFiled: October 12, 1999Date of Patent: December 12, 2000Inventor: Friedrich Fischer

Patent number: 5947154Abstract: The container is used for liquids and is equipped with an outlet to which a discharge hose with an interior hose space can be connected. The outlet is disposed in a container wall which encloses an interior space of the container. In the region of the outlet, a through-passage which leads to the interior space of the container, is disposed. The outlet is connected to a two-position valve which has at least two control positions. A discharge position and an aerating position are being provided. In the discharge position, the two-position valve connects the interior space of the container to the interior space of the hose. In the aerating position, the end of the discharge hose, which faces the interior space of the container, is connected to an area outside the container by means of the two-position valve.Type: GrantFiled: January 27, 1997Date of Patent: September 7, 1999Inventor: Friedrich Fischer

Patent number: 5894632Abstract: An energy storing spring joint (100) for use between two parts movable with respect to each other and joined by the energy storing spring joint is capable of storing energy in such a way that energy is stored in a displacement path and is released in very precise and predetermined manner, with a variable force over the path of displacement, when the parts move in the opposite or backward direction in the path of displacement. At least one energy storing member (50) or at least two energy storing members (50) connected sequentially or at least two different energy storing members (50) connected in parallel are mounted in or on the energy storing spring joint (100) and may be moved by or loaded with energy when one of both parts (30, 40) is moved relative to the other part. The energy storing member(s) (50) may be locked against releasing their energy.Type: GrantFiled: March 19, 1997Date of Patent: April 20, 1999Inventor: Friedrich Fischer
