Title: Inductive hardening control circuit - multiplies induction current and voltage and integrates product
Inventor: RUMP WILHELM
IPC: G01R21/00
Filed: 1973-05-05
Abstract: A control circuit to monitor an inductive hardening operation applies voltages, which are proportional to the induction current and to the induction voltage, on the inputs of a multiplier. Its output feeds an integrator which is synchronized in its function with the heating operation. The total heat to a workpiece can be read on a measuring instrument. The integrator can be discharged automatically a certain interval after the completion of the hardening operation, or manually by a clearance key. This is much less costly than an optical temp. control by radiation pyrometers. It is independent of any obstruction by scale, vapours or the inductor.

Title: Stator shifting displacement mechanism - provides radial and axial adjustment with screws on housing and orthogonal supports on fixed rotor frame
Inventor: HUHN JOSEF
IPC: H02K15/16
Filed: 1973-06-15
Abstract: The displacement mechanism is used to adjust the air gap or the winding position by moving the stator and its housing radially or axially w.r.t. the rotor mounted on a fixed frame. The frame has prismatic recesses, forming a line parallel to the machine horizontal shaft and accepting vertical aligning rods whose ehads act as supports for threaded pins running parallel to the shaft and mounted at one on the machine housing. The pins pass through threaded holes in the heads of the aligning rods so that, when the pins are rotated, the stator and housing are displaced axially. An orthogonal second set of pins supports, and recesses are used for the radial displacement.

Title: Combustion piston engine has airtight crank case - connected with engine inlet down stream of throttle and limited leak-off piston rings
Inventor: DE BIASSE RICHARD L
IPC: F01M13/02
Filed: 1973-11-15
Abstract: The crank case is fully sealed to atmosphere, so that it can hold a vacuum. The connection between crank case and suction duct is unobstructed so that the pressure in the crank case remains substantially equal to that in the suction duct. The piston ring arrangement is such that leakage from the combustion chamber into the crank case is limited to an amount which is less than the flow capacity of the connection. The connection may contain a non-return valve to prevent flow from the suction duct into the crank case. The inlet valve cover may also be sealed to atmosphere and the connection may be arranged via the inlet valve housing to the inlet duct.
