Title: Impact resistant glass incorporating asymmetric laminates - for light weight with progressive resistance to penetration
Inventor: BREITENBRUEGER GERTRUD
IPC: B32B17/10
Filed: 1975-05-31
Abstract: Impact resistant glazing comprises one solid sheet of glass as an external pure 6-20 mm thick separated by a n air gap from an internal pane which is composite, asymmetric sheet >=5 mm thick of layers of glass of diminishing thickness separated by intermediate layers of plastic film, of which at least the film nearest the interior of the buildings is >1 mm thick. Suitable for bullet proof or shrapnel resistant glazing for shop windows, limousines, etc. The surface layers are more scratch- and sunlight-resistant than glazing made of transparent plastics. The progressively increasing flexibility of the constituent layers of the internal pane give successive energy loss from impinging objects penetrating the structure, to provide a much higher impact resistance/weight ratio than solid glazing which offers the same impact resistance.

Title: Power distribution system with short circuit immune HV ring - has current rating equal to multiple of individual circuit ratings
Inventor: CHRIST WALTER DIPL ING
IPC: H02H3/16
Filed: 1977-03-22
Abstract: The purpose of the circuit arrangement is to reduce the need for bringing very high voltage feeders into urban areas in order to support a growing load demand. A high voltage outer ring system at an acceptable value of voltage, typically 110 kV, is constructed with galvanically isolated phases, and in a manner such that it is immune to short circuit faults. Any earth faults are limited by suitably rated earthing resistors. The voltage of the highest voltage distribution circuits is made less than or equal to, that of the ring. The current carrying capacity of the ring is a multiple of that of the individual distribution spurs. Galvanic separation can be achieved by using single phase transformers and switchgear throughout the ring. Double earth faults can be guarded against by rapid tripping of any earth fault.
