Abstract: A substantially closed nursing mug having an upper discharge nipple (31) and a vertically extending dosing chamber (18) adjacent to a side wall portion (3a) of the mug, the volume of the dosing chamber corresponding to a predetermined liquid volume to be drunk at a time. Upper and lower valves (11, 12) are disposed at the upper and lower ends, respectively, of the dosing chamber (18). The upper valve (11) is adapted to automatically switch from a closing position to an opening position when the mug is tilted beyond a first tilting angle, and the lower valve (12) is adapted to automatically switch from an opening position to a closing position when the mug is tilted beyond a second tilting angle being less than or substantially equal to the first tilting angle.

Abstract: A device for feeding a dosage of mashed food into the mouth of a patient. The device consists of a spoon-like feeding head (10) having an internal feeding channel (11), which is connected to a tubular, flexible container (20). The latter can be compressed for feeding a dosage by two mutually pivotable handle pieces (30,40).

Abstract: The present invention concerns a gripping device provided with gripping claws (16) at one end of a tube (3), and at the other end of the tube (3), an operating handle (1). This handle (1) includes a trigger key (5) which is pivotable in the handle. During this pressing the key actuates a push rod (6), one end of which being pivotably mounted in the trigger key (5) and the other end of which being displaceably arranged in the upper portion of the operating handle (1).

Abstract: The present invention relates to a toggle joint, specially to an angular positioning device for a gripping means for gripping tongs where the movements of the tong jaws of the gripping means are regulated by a control cable whose one end is fixed in the gripping means and whose other end is connected to an operating trigger in the handle of the gripping tongs. Said device is formed as a toggle joint having two cooperating joint surfaces designed with locking means which engage one another and forming clutch couplings.
