Patent DE-3207141-A1 (DE)
Title: Storage device, especially for heavy discoid or roller shaped stored material
Inventor: THUMM HEINZ
IPC: B23Q3/155
Filed: 1982-02-27
Abstract: The storage device is especially suitable for heavy discoid or roller shaped stored material, such as grinding wheels or other tools and rolls of paper. It includes a supporting column arranged vertically on a storage rack and a plurality of brackets to receive the material to be stored, which brackets project in front of the supporting column on at least two levels in an essentially radial manner and are pivotable in relation to the storage rack about the axis of the column. There are at least two and preferably four brackets arranged at an angular distance from one another on each level. The said brackets may be either fixedly arranged on the supporting column, if the latter is rotatably mounted on the storage rack, or rotatably mounted on the supporting column, if the latter is fixedly arranged on the storage rack. The preferred arrangement is for the brackets to take the form of cylindrical shaft ends for reception of discoid or roller-shaped material to be stored which has a corresponding axially symmetrical shaft opening and is arranged with a horizontally aligned axis. This design is especially advantageous for heavy grinding discs or rolls of paper which are also used in the machines in question with a horizontally aligned axis and therefore do not have to be tipped for loading and after unloading. A self-supporting cylindrical metal casing which surrounds the column in a concentric manner, is accessible from the outside via a lockable opening segment, offers reliable protection against damage and contamination of the stored material and occupies the smallest possible amount of space is advantageously used as a storage rack. A loading crane which is rotatable about the column axis can be provided on the casing for loading and unloading the stored material. <IMAGE>

Title: Protection device for the end of a tube provided with an internal or external thread
Inventor: REES MANFRED
IPC: B65D59/06
Filed: 1982-03-09
Abstract: The protection device for a tube end provided with an external thread or internal thread is designed as a cap or nipple in accordance with the thread arrangement and as a hollow body with a conical shell, on the circumference of which tabs as supports for threaded portions are punched out and, in the case of the cap, bent inwards and, in the case of the nipple, bent outwards. The tabs are arranged in such a way and designed with an elasticity such that, due to the axial force which arises during the tightening of the protection device by the resting of the latter against the tube end, they are pressed against the thread and wedged firmly there with their threaded portions. In addition, the elastic design of the tabs allows these threaded portions to be pushed over the thread to be protected, as a result of which the protection device can be tightened with just a few turns. The cap rests by its base and the nipple rests by an outward-projecting collar against the end face of the tube. The cap has a bead-like edge region of the base by which it rests against the end face of an inner chamfer of the tube end.

Title: Electrical storage battery with electrolyte flowing through the electrodes
Inventor: KAPPUS WOLFGANG DR
IPC: H01M2/38
Filed: 1982-04-03
Abstract: A storage battery cell (1) having electrolyte flowing through porous electrode plates (5, 6) can be constructed by producing an alternating pressure difference between an upper electrolyte space (3) and a lower electrolyte space (4) which are separated by a false base (2). As a result of blowing up a pressure sack (9) in the electrolyte space (4), the nonreturn valve (13) is closed and the electrolyte is displaced into the upper electrolyte (3) through hollow channels (7) having perforated walls, which pass through the electrodes (5, 6) and the false base (2). Venting by means of a pressure valve (11) collapses the pressure sack (9) and the hydrostatic pressure across the nonreturn valve (13) causes it to open, with the result that electrolyte flows back into the lower electrolyte space (4). <IMAGE>

Patent DE-3222288-A1 (DE)
Title: Identification means with microprocessor and input keypad
IPC: G07C9/00
Filed: 1982-06-14
Abstract: Identification means, particularly plastic cards with memory device, could only hitherto be used in connection with a terminal. For security reasons, the user must key a personal identification number into the terminal which compares it with a stored identification number. The plastic card according to the invention has a keypad by means of which the identification number and other data can be directly entered into the card. The microprocessor with a timer processes these data so that the card itself checks identity, time validity and the maintenance of agreed conditions (credit limits) in each case as a function of time and blocks its use in the case of deviations. To output data, the card has at least one display, a signal transmitter or a loudspeaker which can also be used as microphone for voice output. The card carries out the required arithmetic and memory operations by itself without terminal, and displays the results itself. Since input and output can also be done electronically, however, it is also possible to use it in connection with a terminal.
