Patent DE-3033402-A1 (DE)
Title: Film drive control for projector or cine camera - regulates motor speed and torque to maintain constant film tension as load on take=up spool increases
Inventor: ACKERMANN MANFRED
IPC: G03B21/42
Filed: 1980-09-05
Abstract: The DC motor for the cine drive is in series with a resistor chain (11,12) linked to a transistor-switched voltage divider. The motor speed is regulated w.r.t. the torque so that for increasing centrifugal force on the film take-up spool the motor speed is reduced and hence the film tension maintained within set limits. The motor drive operates automatically in response to the voltage across the motor. As the motor load increases, and the motor tries to draw more current the transfer switches reduce the effective voltage and hence the motor speed. Damage to the film is avoided. The simple control circuit is compact enough to fit small cine cameras.

Title: Byte configured data block transfers - has fifo buffer storage at each end of data bus between processors
Inventor: GUZMAN-EDERY JORGE DIPL ING
IPC: G06F15/167
Filed: 1980-12-20
Abstract: Byte structured data transfers between processors are effected over a data link containing buffer storage. The output from one processor is transmitted to a buffer memory (1) of the first in - first out (FIFO) type. Output from the memory is transmitted to a second memory (2) of the same type coupled to the second processor. Control logic circuits (4,5) respond to external inputs and to output ready (OR) and input ready (IR) signals from the buffer memories. Both units generate shift signals to control the memory transfer operations. The memories allow blocks of data to be transferred.

Title: Process and apparatus for increasing the storage life of linseed grains
Inventor: HITZE WINFRIED PROF DR
IPC: A23B9/10
Filed: 1981-09-12
Abstract: The invention initially relates to a process for increasing the storage life of linseed grains for food use by thermal treatment. The linseed grains are heated up to a treatment temperature in a heat-up stage and are kept at the treatment temperature in a treatment stage. They are then cooled in a cooling stage. A treatment temperature in the range of about 100 DEG C is employed. At the beginning of the process, the linseed grains have their natural water content of 7 to 10% by weight, preferably about 9% by weight. The water content of the linseed grains is increased in the heat-up stage to 12 to 15% by weight, preferably about 13% by weight. The linseed grains are then kept at this water content in the treatment stage at treatment temperature, which can increase in this case by a few degrees. After this, in the cooling stage the water content of the linseed grains is again reduced to a value lying in the range of the natural water content. The treatment in the heat-up stage and in the treatment stage is preferably carried out using saturated steam of appropriate temperature. In the cooling stage, the linseed grains are cooled by a dry air-stream and at the same time dried to the given water content. The invention additionally relates to an apparatus for carrying out the process, which is designed as a drum oven, preferably a rotary tubular oven.

Inventor: OKUN DAWID ISAKOWITSCH
IPC: B21C47/30
Filed: 1981-12-18
Abstract: The present invention relates to the field of metallurgy and relates in particular to auxiliary equipment for rolling mills. The reel comprises a housing (1) in which a reel drum (2) is rotatably mounted. The drum (2) has a free end which is supported on a swing-out support (3) and is designed as a hollow shaft (4) with expanding segments (5 and 6). A connecting rod (9) is arranged coaxially inside the shaft (4) so as to execute a reciprocating motion longitudinally with respect to the shaft (4). The rod (9) interacts with the expanding segments (5 and 6) of the shaft (4) by means of the wedges (10) arranged on the shaft (4). Accommodated in the interior of the housing (1) is a set of compression springs (17) which are arranged coaxially to the shaft (4) of the drum (2). In this arrangement, the springs (17) are supported at one end on a stop (18) attached to the shaft (4) of the drum (2) and, at the other end, on a bush (19) rigidly secured on the connecting rod (9) and interacting with the drive (8) for the displacement of the rod (9) when the drum (2) is compressed. According to the invention, the wedges (10) on the shaft (4) of the drum (2) are arranged in such a way that they can be displaced longitudinally relative to the connecting rod (9). In this arrangement, the wedges (10) are connected to the rod (9) by means of a driving mechanism (11) in order to guarantee different strokes of the wedges (10) for the same stroke of the connecting rod (9). The present invention can be employed with particular advantage in the cold rolling of steel strip and nonferrous metals on single-stand reversible and nonreversible rolling mills and on multi-stand rolling mills. <IMAGE>
