Title: High frequency surgical operation appts. - provides stimulus current at electrode to contract muscles otherwise unseen
Inventor: TAMMEN HEINRICH DR MED
IPC: A61B18/16
Filed: 1974-05-02
Abstract: In a transurethral resection operation, the electrode supplied at high frequency can cut deeply enough to remove all the unwanted tissue, but at the risk of damaging the musculature that closes the bladder, and so leaving the patient incontinent. The risk arises because the muscles concerned are invisible under a mucous membrane. The invention proposes a switching device to enable the high-frequency current at the electrode to be replaced by a stimulus current which can cause the muscles to reveal their where-abouts by contracting. The principle is general application and not restricted to this particular operation.

Abstract: In a process for mixing fluids or flowable powders, using an appts. provided with mixing passages in which the materials are divided into streams which flow downwards at an angle in intersecting streams under gravity, the components of the mixt. are first divided into portions and the streams of the portions are brought into contact with those of other components. The resulting streams of mixed components are then divided into sep. streams which are subsequently recombined. This operation is repeated as often as necessary. The mixing operation is carried out quickly in a small space.

Title: Motor drive system - for multi spindle draw-twisting machine with synchronous feed roll and godet drives
Inventor: WOLF HORST DIPL ING
IPC: D01H1/32
Filed: 1974-07-03
Abstract: In the starting up of a spinning, twisting or wind-up machine and more especially a draw-twisting machine with feed rolls and godets driven by individual synchronous motors, the driving a.c. of all these being produced by a common synchronous generator with rotating rotor driven for the purpose of the synchronised starting and stopping of all the feed rolls and godets by a variable speed d.c. motor, the individual synchronous motors being switched on simultaneously with the synchronous generator, the improvement whereby (i) starting from a synchroniser speed below the operating speed, for the drive assembly consisting of d.c. motor and synchronous generator, a command is delivered for full speed and (ii) the full speed operation is brought about by switching in the individual synchronous motors and after running these up to synchronous speed the order for maximum speed is cancelled. Avoids the need for overdimensioning of the drive assembly of d.c. motor and frequency generator due to the need to start up simultaneously a very large number of individual synchronous motors.

Title: Linear motor for typewriter carriage drive - has control time constants reduced using compensation coil to counteract effects of control loop measuring coil
Inventor: HEILMEIR ERNST
IPC: H02K41/035
Filed: 1974-11-22
Abstract: The linear motor has its control time constants reduced by incorporating a compensation coil (8) in the same magnetic circuit as the measuring and drive coils (4, 5). The typewriter carriage is driven along two ferromagnetic plates by the drive coil which is mechanically coupled to the measuring coil. The measuring coil has a current induced in it that describes the carriage motion and is used for regulating the current in the drive coil. The compensation coil is coupled in series with either the drive or the measuring coils and has the opposite winding sense. The compensation coil counteracts the measuring coil effect on the carriage motion.
