Title: Pulse generator with high switching frequency - has pulse duty factor determined by two control voltages applied to operational amplifier integrator feeding hysteresis switch
Inventor: RABUS FRIEDRICH DIPL ING
IPC: B60T13/66
Filed: 1977-07-16
Abstract: The pulse generator has its pulse duty factor determined by a control voltage (U1) applied to an integrator (2, 3, 4, 6, 7) whose output is connected to a switching circuit with hysteresis (11, 12, 14, 16, 17). The switching circuit's output controls is superimposed as a second control voltage (U2) on the first. The application of this second voltage is controlled by an FET (8) whose gate is coupled to the switching circuit's output. Both the switching circuit and the integrator are built around operational amplifiers. The circuit achieves a high switching frequency and is suitable for use in controlling hydraulic couplings in vehicles.

Title: Length trimmer for multi-blade wood saw - uses spaced switches and signal store to activate advance lopping saw where necessary
Inventor: BEHA CHRISTIAN
IPC: B27B1/00
Filed: 1978-03-22
Abstract: The trimming unit is for by-products for a multi-blade saw frame.

Title: Milking machine control system - uses flow rate to vary suction by adjusting section of milk transfer line
Inventor: HAPPEL FRITZ
IPC: A01J5/04
Filed: 1978-07-24

Title: Sacrificial anode for cathodic boiler protection - with indicator plunger for anode exhaustion unaffected by temp. changes
Inventor: HOESSLE LUDWIG
IPC: C23F13/02
Filed: 1979-05-10
Abstract: Sacrificial anode consists of a metal bar which is bonded to a metal cap to hold it in a boiler wall. A blind hole in the upper part of the anode leads to a cavity in which a small red piston can slide. An O-ring prevents the piston movement due to temperature changes but the entry of boiler water moves the piston outward so that its stem protrudes outside. This indicates that the sacrificial anode is due for renewal, without false alarms by temperature induced changes.
