Title: Generator driven by water turbine - has stator punching segment angle to pole pitch ratio designed to give min. force at joints
Inventor: DETINKO FELIKS MOISEEVITSCH
IPC: H02K1/16
Filed: 1978-05-13
Abstract: In large water turbine driven generators the magnetic forces at the joints in stator punching segments can result in loosening of the core in a circumferential direction. This effect can however, be almost entirely eliminated by a specific choice of dimensions. The angle subtended by the punchings is chosen such that when multiplied by the number of pole pairs on the rotor the product is divisible by pi. The result is that the flux density on adjacent sides of a segment joint is equal and opposite, resulting in zero circumferential force.

Title: Testing circuit for mass-produced electronic components - compares measurement to output stored on capacitor and gives output corresp. to mean of measurements
Inventor: OTTEN HANS
IPC: G01R17/02
Filed: 1979-04-12
Abstract: The input measurement (1) is compared to the output which is stored on a capacitor (3). When the input is larger or smaller than the output, a relay tries to connect a positive or a negative source to the capacitor. The connection is only made for a fixed length of time when a trigger input is applied to a pulse generator (11). The output, therefore, settles down to give an output corresponding to the mean of a series of measurements and has application to the testing of mass produced components. The pulse duration can be varied as a function of the test number to reduce the output variations with later measurements.
