Title: Method of cooling and calibrating elongated objects made of plastic and a cooling and calibrating equipment
Inventor: PURSTINGER FRANZ
IPC: B29C48/90
Filed: 1995-02-21
Abstract: The invention describes a process for cooling and if necessary calibrating elongated, especially continuously extruded objects (7) made of plastic as well as a cooling and calibrating device (5) for carrying out the process. With this the object (7) during its advancement in the longitudinal direction is exposed in consecutive regions (13 to 18; 86 to 89, 95 to 97) to a higher vacuum in each case and is cooled with respect to the initial temperature to a lower final temperature. The heat to be removed for cooling is extracted by a coolant washing round the object (7). The individual regions (13 to 18; 86 to 89, 95 to 97) in the transport direction of the object (7) are separated from each other from the covering plate (35) or the base plate (43) to the height of the object (7), whereupon by means of the vacuum a coolant on one longitudinal side of the section is drawn into a chamber of the region and is raised over the upper edge of the object (7) or a support diaphragm (81) extending transversely to the longitudinal direction from the base plate (43) to approximately the height of the object (7). The coolant overflows into a flush chamber (46; 102,107) located on the opposite longitudinal side of this region (13 to 18; 86 to 89, 95 to 97) or of the object (7) or of the support diaphragm (81) through an immediately following region (13 to 18; 86 to 89, 95 to 97) in the extrusion direction and is thereafter drawn into the tank (22) or into this following region (13 to 18; 86 to 89, 95 to 97).

Title: Connecting fitting for heating elements, the heating element, process for producing such fitting and its use
Inventor: SEIDL HERMANN
IPC: F24H9/12
Filed: 1997-05-23
Abstract: The invention concerns an adapter for use in refitting radiators (14), a radiator (14) fitted with such an adapter and a method of manufacturing the adapter. The adapter has a mounting (1) which can be attached to the radiator (14) at any desired point, pipe connection pieces (3, 4) on the mounting (1), connection fittings (8, 9) for connecting the adapter to the radiator terminals (15, 16) and lines (6, 7) each of which connects a connection fitting (8, 9) to its associated pipe connection piece (3, 4). The terminals are preferably located underneath the radiator at one end, and the mounting is attached to the centre (18) of the radiator, thus ensuring that a radiator fitted with an adapter can always be connected up, irrespective of its width, to centrally laid heating pipes so that it is centred. In the method proposed, two pipes (6, 7) are cut to the same length, attached to the pipe connection pieces (3, 4) and the connection fittings (8, 9) and bent to shape so that they lie next to each other at the same height.

Title: Rain sensor
Inventor: PIENTKA RAINER
IPC: G01V8/14
Filed: 1995-02-03
Abstract: Proposed is a rain sensor in which an effective optical radiation (11) is subjected to at least one total internal reflecti1n in a pane (16). The effective radiation (11) emerging from the pane (16) at the end of a measurement path (24) into an output unit (22), plus any background radiation (31'), are incident on a separation surface (25) at which only the effective radiation (11) or the background radiation (31') undergoes total internal reflection. This surface (25) makes it possible to separate the background radiation (31') from the effective radiation (11) before it is incident on a radiation-measuring instrument (30). The rain sensor proposed is particularly suitable for use in motor vehicles in conjunction with a windscreen-wiper system which is operated automatically by the sensor.
