Patent DE-2708882-A1 (DE)
Title: Electronic energy meter power supply - operates with sampling circuit for checking and regulating output voltage
Inventor: KUSCHE PETER DIPL ING
IPC: H02M7/06
Filed: 1977-02-25
Abstract: The application is to power supplies for energy meters, for example watt hour meters or devices for measuring thermal energy, which employ electronic circuits. The power supply is composed of a switching circuit (N) whose output is at high frequency and typically sinusoidal. It incorporates a regulating circuit, preferably based on a sampling system, which compensates for variations in the primary supply from the system (R,S,T). The mains voltage is provided with surge arresters (B, Cp) and a clipping capacitor (CL) after the rectification stage. Spike diverting capacitors may also be added to the output of the switching circuit (N). These devices ensure that no fast transients get through to the electronic circuits. By dropping the mains supply through series resistors (RV) low voltage switching transistors can be used in the switching circuit (N). This gives increased life and reliability.

Title: Correction for uneven illumination in wide angle ophthalmoscope - using moving blinds operating from sides of observation field to mask over bright areas
Inventor: POMERANTZEFF OLEG
IPC: A61B3/125
Filed: 1977-03-25
Abstract: The retina is illuminated the sclerotic and observed through the lens. This gives even illumination across most of the image, but over-brightness at the edges. Correction is by selective masking of the image. The masking is pref. by moving blinds inwards from the sides of the field of observation to cover approximately the over-bright areas. A motor drive can be used, and the movements synchronised with those of a camera shutter. Illumination is pref. by two bundles of optical fibres. An existing ophthalmoscope with only a single light source can be adapted by switching the light alternately from one fibre bundle to the other. This, too, can be motorised and synchronised with the movements of the blinds and the camera shutter.
