Title: Electric motor emergency supply system - is for three phase motor with cycloconverter and uses continuous triggering of rectifier unit
Inventor: ISHIBASHI HIDEO DIPL ING
IPC: H02H7/085
Filed: 1976-08-26
Abstract: The object is to allow operation of the equipment during transient mains interruptions and voltage dips without recourse to the use of batteries or emergency supplies. A system monitor (19) detects an interruption and generates a signal to apply continuous triggering to all the thyristors in the controlled rectifier (2). At the same time it also signals a change of operation to the speed control elements so that a zero error is maintained. The reference signal is reduced to match the fall in motor speed which results in a reduction of inverter (4) output frequency. Synchronism is thus maintained during the transient period. Restoration of the supply reverts the system to normal control, and a controlled acceleration of the motor back to the original set operating point results.
Patent DE-2639738-A1 (DE)
Title: Cylindrical lifting cell with flexible shells - has stretching shell with inwards buckled shell in rest condition
Inventor: KREBS GERD
IPC: B66F3/35
Filed: 1976-09-03
Abstract: The cylindrical lifting cell requires no servicing, and the force application can be significantly increased before the end position has been reached without special arrangements. The axial force increases together with the increasing stretching of the lifting cell until final stretching has been reached. The stretching force increases together with constant internal pressure and this ensures wide new application ranges for this lifting cell. The lifting cell has two stacked plates connected with sealed thick walled tubular shell. The latter is made from flexible plastics with modulus of elasticity of about six hundred kilograms per square centimetre. The middle annular zone of the shell is buckled inwards when the arrangement is not pressurised. The circular buckling zones are formed by the circular notches on the stretching side. One of the plates can be made integrally with the shell.
