Title: Motor overload protection circuit for power saws - is fitted with thermal trip contact opening no-volt coil circuit to trip motor circuit OFF
Inventor: HAAF SIEGFRIED
IPC: H02H7/09
Filed: 1975-07-16
Abstract: The object is to provide simple overload protection for semi-portable circular saws or similar toolds driven by an electric motor, and to give indication of the cause of trip. The motor start switch (b1) closes the no-volt coil (C1) circuit and the main motor contacts. Incorporated in the no-volt circuit is an additional contact (e1) operated by a thermal sensor in the motor and bridging an indicator lamp (11) across the mains supply. In the event of high temperature in the motor the additional contact opens, and with the no-volt circuit thus open, the motor trips off. The lamp lights signifying an overload trip. If the trip is due to low supply voltage the no-volt coil (C1) drops out, opening the motor circuit as before, but the lamp (11) stays dark being still bridged by the additional contact (e1).

Title: Electric active power and energy measuring - uses circuit for electronic meters converting voltage and current into pulse trains
Inventor: MASSEN ROBERT DR ING
IPC: G01R21/133
Filed: 1976-03-18
Abstract: Active power is measured by formation of product of voltage and current. Mean time value of the pulse trains is proportional to voltage and current. Scanned values of voltage, current and zero potential are converted into pulse train with pulse probability proportional to the variables (votage etc.). This is done by an electronic scanner, a comparator and a random noise voltage source. A logic network generates further pulse trains with pulse probabilities proportional to products or voltage by current and zero potential by zero potential. Zero point errors of converters are eliminated from the power expression by stochastic subtraction in a reversible counter of the second product from the first.

Title: Supplementary mixture:inflow control device for IC engines - using an electromagnetically operated sleeve to shorten inflow period
Inventor: MUELLER WILLI
IPC: F01L9/20
Filed: 1976-03-24
Abstract: The supplementary mixture-inflow control device for IC engines is intended for engines with poppet inlet valves. The control device (3) comprises a cylindrical sleeve (6) which is a sliding fit in the part of the inlet duct adjoining the valve seat (4) carried on 3 webs (9) at one end of a guide sleeve (8) around the valve stem (7). At its other end, the guide sleeve has a radial flange touching an annular electromagnet (10) fitted over the valve guide (11). A helical spring (12) around the valve stem abuts on that guide with one end; on a step (13) in the guide sleeve with the other. When energised the magnet overrides the spring and keeps the device inactive; de-energised; it allows the sleeve to seal against the open valve, stopping the mixture flow before the valve would. This improves the engine part-load efficiency. The bottom of the guide sleeve is shaped to minimise the impact when the released sleeve seats against the valve head (14).
