Patent DE-3244775-A1 (DE)
Title: Arrangement of suspension loops
Inventor: NIEDECKER HERBERT DIPL ING
IPC: A22C11/12
Filed: 1982-12-03
Abstract: In the arrangement of suspension loops closed on themselves on a carrier band for mechanical feeding to closing machines for tubes and bags, especially sausages, difficulties occasionally arise with the use of individual loops made by means of a knot, because the part loops in which the knot is located can easily twist. Moreover, the knot can cause faults in the feed of the loop. To prevent these disadvantages, the loops are interconnected on the carrier band by means of the yarn from which they are formed, and this yarn is a filament yarn, from which the loops are formed in that the yarn overlaps in a part region and the overlapping yarn portions are connected at least partially to one another.

Patent DE-3308437-A1 (DE)
Title: Under-voltage trip device for electrical low-voltage protection circuit breakers
Inventor: VOGELSANG WERNER
IPC: H01H83/12
Filed: 1983-03-10
Abstract: The under-voltage trip device (7) operates on a transmission element (11) of the protection circuit breaker, which element leads to the protection circuit breaker (1) tripping when the required control voltage is not reached. A leading auxiliary switch (8) connects the under-voltage trip device (7) to voltage prematurely in the switching-on phase. At the same time, a tab (9) which is located on a switching-on push-button (3) of the protection circuit breaker operates (during the movement of the push-button into the on position) a pressure lever (10) which releases the magnetic armature (17) of the under-voltage trip device (7). If the voltage which is applied via the leading auxiliary switch (8) is sufficiently high, then the magnetic armature (17) remains in the attracted position and the protection circuit breaker can be switched. However, if the voltage is not adequate, then the magnetic armature (17) trips off. At the same time, a trip slide (12) is operated via a deflection lever (21) which is hinged on the armature, which trip slide (12) acts directly on a latching mechanism (2) via the transmission element (11), and hence prevents the circuit breaker (1) being switched on. <IMAGE>

IPC: G01R31/36
Filed: 1983-04-13
Abstract: The invention relates to a method and a device for clamping, fastening and removing a sheet-type recording medium (90) in a recording apparatus. A roller body (10), constructed as a negative pressure hollow cylinder, is driven in rotation about the longitudinal axis (X) of a first shaft (12) for the recording operation and, for fastening the recording medium (90), has a suction channel system (5), which is known per se, and, for clamping and removing, a device (30) which comprises a plurality of gripper elements (35), which are mounted on a second shaft (31) and are operatively connected thereto, and at least one actuating member (33). The recording medium (90) is clamped on the roller (100) in a position of rest in which the gripper elements (35) are swivelled into a first open position by the engagement of a first switching runner (50) with the actuating member (33) and held by the negative pressure during the rotary movement, the gripper elements (35) being swivelled into a second open position, during the decelerated rotary movement, by the engagement of a second switching runner (55) with the actuating member (33) and the recording medium (90) is thus lifted from the roller (100), led off and removed. <IMAGE>

Title: Wall, sheet or the like of lightweight-metal profiles
Inventor: JACOBS HELMUT
IPC: B62D33/04
Filed: 1983-04-27
Abstract: The invention relates to a wall, sheet or the like of a plurality of lightweight-metal profiles in stacked arrangement and connected to one another. To increase the flexural and shear strength, the invention provides for the ends (4, 5) of the lightweight-metal profiles (2, 3) to be designed so as to have a U-shaped cross-section and for adjacent ends (4, 5) to be guided into one another or onto one another. The profile ends (4, 5) thus form a hollow chamber (6) which is closed at the top and bottom by lateral webs (12) of the adjacent profiles (2, 3) and which is filled with a chemical material (7) after the profile ends are plugged together. The profile ends (4, 5) and at least one of the lateral webs (12) are provided with projections (8) or recesses (9) with undercuts (10) which are enclosed by the chemical material (7). The chemical material thus acts as a positive connecting element which holds the profile ends (4, 5) together. In order to increase the shear strength, the recesses (9) or the projections (8) can be roughened. The lightweight-metal wall (1) according to the invention is especially suitable for vehicle bodies, for example side-boards of load platforms, walls of van bodies or the like. <IMAGE>

Patent DE-3325802-A1 (DE)
Inventor: MALY ZDENEK
IPC: C25F3/04
Filed: 1983-07-16
Abstract: Pretreatment of aluminum strip or foil (40) for lacquering, adhesive coating or laminating processes involves heavy metal compounds which are considered undesirable for many packaging purposes, in particular for foodstuff packaging. These disadvantages are avoided if the strip or foil is pretreated in an electrolyte by subjecting it to a three phase alternating current of which one phase is rectified and the side of the strip or foil to be treated is made to pass in sequence three electrodes of which at least one is connected to the rectified phase while the others are connected to the other phase of the alternating current. Such a pretreatment has the advantage over an alternating current treatment that the oxide layers offer high strength of adhesion and the treatment can be performed faster.
