Patent DE-3529746-A1 (DE)
Title: Process and equipment for the manufacture of bags
Inventor: HONSEL KARL-HEINZ
IPC: B31B160/10
Filed: 1985-08-20
Abstract: Flat bags and gusset bags are fabricated from a piece of tubing whose transverse edges formed by the tubing walls extend at a mutual offset. In the process according to the invention, the upper ply of the tubing and, if appropriate, the plies of the gussets are severed by means of a smooth-cutting knife, while the lower ply is torn off with the aid of a previous perforation. Since an upper edge is formed in the finished bag by the upper ply of the tubing, the impression is created that the bag is fabricated by smooth cutting. The machine operating according to the process is particularly quiet, since there is no contact between the smooth-cutting knife and the cutting roller located underneath (Figure 2). <IMAGE>

Title: Process and circuit arrangement for automatically controlling the start/stop behaviour of the drives of mechanically driven storage devices
Inventor: BREITBACH GABRIELE
IPC: G11B19/20
Filed: 1985-09-06
Abstract: With the aid of counting devices, it is determined how often data messages which must cause the drive of a mass storage unit to start up are received. For this purpose, in each case a time value and the number of the data messages during this time are fed to a control device. A quotient is formed from this, whereby an optimum value for a delay time by which the drive of the mass storage unit is later switched off is determined. The delay time may be adapted automatically to the respective volume of traffic of the data messages. According to a further development of the invention, with the aid of an intermediate storage unit a delay in the switching on of the drive can also be achieved, by the point in time of switching on being governed by the variable filling level of this intermediate storage unit.
