Abstract: A hose connector comprises (a) a tubular nipple comprising one end insertable into an end of a hose, the one end defining an annular shallow recess of a depth of 0.2 mm to 0.

Abstract: The electrically driven can opener is composed of a housing (1) accommodating a drive mechanism, a drivable drive wheel (2) which is located on the outside of a housing wall (3), a cutter (8) rotatably supported on the housing wall (3) at a distance from the drive wheel (2) and an operating member (22) to be operated by hand and mounted on the housing (1), which latter member serves to swivel the cutter (8) from a clamp-on position into a cutting position and to switch on the drive motor by means of a switch (38). The operating member (22) and the cutter (8) are interconnected by a spring-elastic element (19).

Abstract: The invention discloses a can opener having a driving wheel (4) which is adapted to be driven by a drive unit, is rotatably mounted on a housing (1) and which, for the purpose of propelling a can (24), engages from outside under the seam (6) at the point of engagement (29). Above the lid (10), a cutter (3) is mounted on the housing on a pivot shaft (13) at a predetermined distance from the driving wheel (4), the cutter being movable from an initial position (20) into a cutting position (28) and having a piercing tip (17) and an adjoining cutting edge (8) with a cutting area (9) which is in engagement with the lid (10) when in the cutting position (28). To guide the can (24), a first abutment stop (7) is provided on the housing (1), being secured to the can opener rearwardly of the point of engagement (29) when viewed in the direction of movement ( 12) of the can (24).

Abstract: The tire filling unit, particularly for filling a bicycle tire, comprises a filling head with an outlet connectable to a filling valve of a tire and with an inlet containing a hollow prong for a high pressure gas cartridge and a concentric cartridge jacket attachable with the filling head at the inlet for receiving the high pressure cartridge. A connecting duct contains an automatically closing valve between the inlet and the outlet which locks the connecting duct in a closed configuration and which is movable into an open configuration by an operating device mounted in the filling head.

Abstract: A regulator device for controllably supplying liquid to a suction means, and having a gate that is adjustable to selectively block and unblock inflow conduits extending into a chamber, such that liquid outside the chamber flows into the chamber through a designated inflow conduit. The inflow conduits have outlets at different heights, the outlet height of each inflow conduit corresponding to the magnitude of suction required to draw liquid from the chamber through an outflow conduit having an inlet below a liquid level in the chamber.
