Abstract: In the weft-thread metering device, a straightening means (17) for holding the weft thread (2) in front of the weft-insertion means (1) in the weaving plane (24) during the raising of the winding head (11) is arranged, for guiding the weft thread, on the lower side of the winding head (11) between the weft-insertion means (1) and the winding head (11) following an endless path. A guide strip (25) for the straightening means (17) is provided in the portion of the path (12) of the winding heads (11), in which these are raised into the inactive position during the separation of the weft-insertion means (1). The straightening means (17) is mounted movably between two reversal points, in one of which it is pressed flexibly against a stop (23) on the lower side of the winding head (11) located in its lower or working position in this time interval, and in the other reversal point of which, and during the entire interval of the raising of the winding head (11), the straightening means is pressed flexibly into the inactive position against the guide strip (25), the surface of which it follows. This measure makes it possible for the weft thread to slip spontaneously between the jaws of the exit thread brake (7) and to be held reliably there. <IMAGE>

Title: Heat exchanger heating cycle for heat pump - extracts heat from environment using intermediate medium in evaporator under vacuum
Inventor: KUPCZIK GUENTER ING GRAD
IPC: F28C1/00
Filed: 1977-05-21
Abstract: The heat exchange system is used in a heat pump. The latter heats a medium for a heating cycle within an evaporator and heat is extracted from air or soil by a gaseous heat carrier. In normal operating conditions and also on matching operating conditions to requirements there are achieved efficiencies making heat pump useful for a wide range of applications. The heat is transferred from the heat carrier medium to the heating medium by an intermediate medium. The freezing temperature of the intermediate medium is lower than that of the liquid component of the gaseous heat transfer medium. The heat is transferred from gaseous medium to a liquid intermediate medium in the evaporator. In this evaporator is vacuum generated which prevents water separation of the heat carrier medium at a given temperature.
