Title: Close range imaging process for eyes focussed further away - using collimating lens so that virtual image plane can be read while accommodating objects at greater distance
Inventor: GEISER GEORG DR
IPC: G02B25/00
Filed: 1978-08-11
Abstract: The optical indication forming method is for presentation of information close to the observer whose eyes are accommodating optical information from a greater distance, e.g. a dashboard for a driver paying attention primarily to traffic conditions. This aids faster reading since the eye does not have to re-adjust itself. A virtual image of the information is presented by means of a collimating lens. The virtual image plane is at such a distance from the observer that it can be read by eyes focussed data greater distance. A Fresnel lens can be used. Correction of colour errors can be by an achromatic lens or a colour filter.

Title: Heat pump assembly avoiding use of compressor - uses absorption unit followed by evaporator for supply of vapour
Inventor: SINGELMANN DIETRICH E DIPL ING
IPC: F01K17/00
Filed: 1979-09-26
Abstract: Heat emanating from a source with low-level temp. is raised to a higher temp. level for use, by a heat pump. Instead of making use of the usual cooling-medium, vapour compressor with mechanical drive, the pump uses an absorption assembly, with an evaporator following it. This may use water as absorbent liquid. The partial pressure of an auxiliary atmosphere may serve to support the circulating pump, and to regulate the extent of saturation of the operative medium. The pumping process can be continuous. Another possible absorbent substance may be a solid, in small particles or pill form. The pump can be installed in a steam power station, to reduce loss of condensator heat.
