Title: Twin independent circulation heat pump system - has thermal coupling system which is connected between both circulation systems
Inventor: SCHROEDTER ROLF DR ING
IPC: F25B7/00
Filed: 1975-02-21
Abstract: A heat pump device has two independent circulation systems with separate working media, and it has both the working media circulation systems thermically coupled by means of heat carrier circulation systems, regenerators or recuperators. Both systems have a region of small pressure and temperature differences by means of which small energy consumption can produce large amounts of heat. The temperature difference between the two circulation systems is bridged by means of a regenerator (4) or recuperator circulating system. One of the circulation systems is directly accessible to the surrounding atmosphere from which it removes heat.

Title: Plain paper printer using thermally fusible toner powder - uses transport unit to bring powder in contact with paper and near printing head
Inventor: HEINZL JOACHIM DR ING
IPC: B41M5/398
Filed: 1975-03-19
Abstract: The printing head (7) which sends out the heat rays is positioned on the opposite side of the recording medium, e.g. paper, from the toner powder so that the heat penetrates the paper in order to fuse the powder in place. The transport unit can comprise a roller with an electrostatically chargeable surface whereby the electrostatic force thereby creasted holds the toner powder in contact with the paper. More specifically the transport unit is a web of black material (8) which passes round the printing roller (10) from a supply roller (9) to take-up spool (11). The paper (3) is also in web form and is brought into contact with the toner carrier (8) by the aid of transport rollers (12).
