Abstract: Container with at least one vacuum enclosure with an access opening, especially a beverage container with a self-cooling device having a vacuum enclosure, such as a beer barrel or the like, the access opening of which is closed off by a closing mechanism after the vacuum is produced, a chamber being provided, which is downstream from the access opening and in which a valve element is disposed, which is opened during the generation of the vacuum and closed after the vacuum is generated, which chamber is filled with a medium containing an element or compound capable of diffusing, which diffuses if the chamber and, with that, the vacuum chamber is not closed off tightly, through the access opening.

Abstract: A tearing mill for comminuting fruits is equipped with a rotatably supported plate having tearing elements And with a stuffing device with a feed screw for delivering the fruits to the plate. A gap of adjustable width exists between the stuffing device and the plate. By means of an independent control of the gap and the rotational speed of the feed screw and plate, a mash structure of the comminuted fruits is achieved which is well adapted to the type of fruits and to subsequent processing of the mash.

Abstract: A cutting tool with a linear oscillating drive has a handle body (1) and a knife (3, 4) which is guided therein and is displaceable in an oscillating manner in the longitudinal direction, the knife (3, 4), by means of a knife holder (4), being detachably connected via a clamping member to a transmission element, arranged in the handle body (1), of the linear oscillating drive. Since the knife holder (4) is cohesively connected, in particular sealed, together with a knife shaft (31), the cutting tool complies with the hygiene regulations for use in the foodstuffs sector.

Abstract: A motor housing (11) is mounted in a handle body (10) so as to slide in the longitudinal direction. A tubular pipe (37) that can slide in a bore (38) of the body (10) projects from the back of the housing (11). Compressed air can be applied to the bore (38) through a switching valve (40). A piston (14) with a piston rod (17) can slide in the housing and a tool can be secured to its front end. A flutter valve (23) which alternatingly connects the bore (38) to the two cylinder chambers (27, 28) is built into the valve housing (22). The piston (14) alternatingly opens the connection to an outgoing air conduit (29-31). A pre-stressed spring (47) is set between the body (10) and the housing (11). In operation, the housing (11) oscillates out of step with the piston (14), so that their initial forces are largely compensated and no vibrations are transmitted to the handle body (10).
