US Patent:

41624360, Jul 24, 1979

Filed:

Aug 29, 1977

Appl. No.:

5/828275

Inventors:

Lindsey E. Waldorf - Ann Arbor MI
Kenneth E. Monroe - Ann Arbor MI

International Classification:

H02P 500

US Classification:

318139

Abstract:

A control system for powering the direct current drive motor of an electric vehicle from a storage battery employs a semi-conductor switch to connect the battery to the motor. Speed control of the vehicle is achieved through operator control of an accelerator which provides an analog output voltage. A multi-vibrator provides a bi-valued output signal varying between 100% on time and 100% off time as a function of the accelerator output. The motor energizing switch is conditioned by this output and by the output of a circuit which compares the motor armature current to a reference value. The circuit includes protection elements so that the switch is opened when the armature current exceeds a preset maximum and is allowed to close again if the multivibrator is still in an "on" mode when the armature current decays below a lower preset value.

Abstract:

An induction heating generator consists of a Hartley oscillator employing a tank circuit, including the induction heating coil, disposed in series with the emitter-collector circuit of the transistor. A bias circuit consisting of the parallel combination of a capacitor and diode is connected to the base and the feed-back voltage to the base is generated by a tickler coil. In the absence of oscillations the base is biased for class A operation and the resulting feed-back current charges the bias circuit to shift the operating point to class C operation. The bias voltage is decreased when the tank coil is loaded, lowering its impedance. This maintains stable operation of the oscillator independent of variations in the load. When the coupling between the load and the inductor is so great as to overload the oscillator, the bias circuit prevents oscillation.

US Classification:

355 77

Abstract:

A method for making a plurality of colored sportscards comprising the steps of forming a master panel with a matrix of borders, each associated with a window area; cutting each window area into a window opening; pasting a photograph behind each window opening; making a colored photocopy of the master panel and the colored photographs; disposing a back panel on the rear of the photocopied panel having indicia related to each of the images within the photocopied window openings, laminating the two panels between a pair of adhesive clear plastic sheets; and then cutting the laminated panels into as many sub panels as there are window openings to form a plurality of sportscards.

The process is repeated so that each individual photograph is made into as many sportscards as desired.
