Inventor: SCHUSTER PETER
IPC: H02K41/00
Filed: 1988-07-12
Granted: 1992-06-02
Abstract: The invention relates to a non-contacting linear drive system wherein the stationary guiding section is designed as a tubular section element. What is essential is the aspect that the rotating conveyor section presets spaced double helices, with the generation of a constant magnetic field in the magnetic circuit constituted by one of the double helices and by the magnetic return path. In that system the permanent magnets are so disposed in the conveyor section/tube that the two helices in close succession present opposite polarities (N-S). With that design a very simple and economic structure and manufacturing process can be realized. The double helix of the conveyor section may be designed so as to comprise permanent magnets introduced into the helices with a radial orientation, or axially extending permanent magnets provided between helices of a soft magnetic material.

Abstract: ABSTRACT      A two-filament incandescent lamp and operating circuit well suited to lighting applications requiring high service reliability.  In the lamp, the rated operating voltage of the second filament is greater that of the first filament.  In the operating circuit, there is an inductive reactance in series with the lamp and, in one aspect of the invention, an electrical connection across the lamp terminals for measuring the operating voltage of the lamp.  After the power and rated wattage of both lamp filaments have been selected, matched values of inductive reactance and open circuit voltage of the operating circuit can be uniquely determined such that the following advantages are obtained.  When the first lamp filament fails, the second filament comes into full brilliance.  In a preferred embodiment of the invention, there will be no significant change in the luminous output of the lamp before and after failure of the first filament.  A positive indication of the failure of the first filament will be provided via the electrical connection across the lamp terminals.  Maintenance personnel, perhaps remotely situated, may replace the lamp prior to failure of the second filament so that service will not be interrupted.  In another aspect of the invention, the electrical connection across the lamp terminals is not included in the operating circuit.  In yet another aspect of the invention, a method of designing a two-filament lamp and operating system having optimum efficiency is described.

Title: Magnetron with microprocessor based feedback control
Inventor: SMITH PETER H
IPC: H05B6/66
Filed: 1988-12-15
Granted: 1992-12-22
Abstract: MAGNETRON WITH MICROPROCESSOR BASED FEEDBACK CONTROL         ABSTRACT OF THE DISCLOSURE     A microwave oven uses a full wave full bridge inverter for supplying energy to a cooking magnetron by way of a power transformer.  The inverter is controlled by a microprocessor which acts upon a control circuit having an oscillator.  Two feedback loops are provided for controlling the operation of the magnetron.  A relatively slow feedback loop uses the microprocessor to adjust inverter operation in order to stabilize the magnetron power output.  A relatively fast feedback loop senses current passing through a primary of a power transformer.  A signal based on the sensed current is provided to a comparator and compared to a reference. If the signal from the current sensor indicates that the current has become excessive, the comparator generates a shutdown signal which will stop the generation of gating pulses to the transistor switches of the inverter.  The relatively fast feedback loop protects the circuitry against sudden current increases which might otherwise damage components before the microprocessor would have time to adjust the inverter operation.

The phototransistors are connected in a current summing network to generate an analog current signal, the amplitude of which is linearly related to the fluid flow.  The output signal is amplifed and connected to output devices.  The analog signal can be reliably transmitted over relatively long distances within the factory environment using conventional low voltage wiring.  A          "dirty" oil monitor is connected to the zero flow phototransistor and includes an LED which is energized at zero flow and with flow if the dirty oil blocks proper light transmission.
