By pressing a second key, information which can be entered via the terminal and which is allocated to the name can be recorded in the information memory.
Patent DE-3434861-A1 (DE)
Title: Air-cooled internal combustion engine with air baffle plate arranged in the air flow
Inventor: WAHNSCHAFFE JUERGEN
IPC: F01P11/12
Filed: 1984-09-22
Abstract: The invention relates to an air-cooled internal combustion engine with an axial fan, on the compressed-air side of which an air duct housing is arranged. The housing is laterally offset in relation to the crankshaft and extends along the cylinder head row of the internal combustion engine. A heat exchanger, through which a secondary air flow passes transversely to the crankshaft, is arranged in the upper area of the air duct housing, whilst the main air flow flows through the cylinder head row transversely to the crankshaft. Dirt particles, which can block the fine air guide ducts in the heat exchanger, are delivered by the axial fan together with the cooling air. In order to remove dirt particles carried in the cooling air flow, it is proposed to arrange an air baffle plate, curved in the direction of rotation of the fan, inside the air duct housing, the free end of which plate lies at a distance from the heat exchanger and prevents the direct air feed to the heat exchanger. The secondary air flow tapped off from the main air flow must flow round the air baffle plate forming an obstacle to the flow, the dirt particles being precipitated and virtually clean cooling air flowing through the heat exchanger. <IMAGE>

Title: Process for the production of a supporting part for flat radiators
Inventor: PETERMANN JUERGEN
IPC: F28F9/26
Filed: 1984-11-03
Abstract: When connecting flat radiators with the aid of a connection piece, a supporting part is arranged respectively in the region of the inlet or outlet of the radiator, allowing the radiator to withstand the mechanical forces involved in pressure welding. In order to guarantee optimum utilisation of material while simultaneously achieving high mechanical strength, the starting materials used in the process according to the invention are two sheet-steel blanks, square in plan view, the corners of which are folded over before the two sheet-steel blanks, joined by a web, are folded onto one another. The folded-over corners, which rest against one another, here form supporting pillars between which there remain flow channels. Before the two blanks are folded onto one another they are provided with central holes and, if required, with a centring collar on the outside. The holes then form axial passage openings which open into the radial flow channels.

Title: Device for winding the flanged bobbins of weft-yarn carriers on wave-shed weaving machines
Inventor: MZYK HEINRICH
IPC: D03D47/26
Filed: 1984-11-10
Abstract: The invention relates to a device for winding the flanged bobbins of weft-yarn carriers on wave-shed weaving machines, having a rotating winding finger disengageable in the event of a bobbin change, and having yarn-guide means for guiding the yarn during the change of the flanged bobbins. The purpose of improving material economy and of increasing the performance of the machine is served by the object of providing a yarn-guide means which, at high working speeds, does not impede a uniform winding build-up on the flanged bobbin and which prevents the last turn from being drawn off from the flanged bobbin during the retraction of the winding finger. According to the invention, the yarn-guide means is a blowing-air nozzle which, at the moment when the yarn is discarded from the winding finger, is directed to the run-on point of the yarn onto the flanged bobbin, in such a way that its longitudinal axis forms an acute to right angle  alpha , but preferably an acute angle with the tangent at the run-on point of the yarn. <IMAGE>
