Title: Axial blower having a front guide wheel
Inventor: LICHTBLAU LEO DIPL ING
IPC: F01P5/02
Filed: 1984-01-20
Abstract: Axial blower, especially for air-cooled internal combustion engines, for generating the cooling air flow, having a front guide wheel, comprising a hub and twisted guide vanes, which is shrunk into the blower shell which has a rounded inflow region. The guide vanes of the front guide wheel are twisted in such a way, that the load-bearing cross-section (2), which is continuous in a radial direction from the inner to the outer diameter, of each guide wheel, with respect to its centre of gravity, is located in the central region of the vanes. The inlet region of the blower shell can thus be extended as far as the anterior part of the shrink fit of the guide vanes. This results either in a shortening of the overall construction of the axial blower or in a more flow-effective radius of the blower shell inlet (Figure 2). <IMAGE>

Patent DE-3503791-A1 (DE)
Title: Gas and smoke alarm
Inventor: SCHAAD ERICH
IPC: G08B17/10
Filed: 1985-02-05
Abstract: A gas and smoke alarm for operation in commercially available plug sockets connected to the public mains, which, in addition to the alarm siren which is located in the apparatus, has the capability to operate an external, and possibly physically separated, siren. A protection circuit prevents the apparatus being damaged if the electrical supply lead or the external siren itself is short-circuited. If this occurs, a built-in light-emitting diode illuminates and indicates the defect. In the event of a power failure, the operation of the apparatus continues to be guaranteed for a short time by the built-in accumulator or the battery. If an accumulator is used, this is charged during normal mains operation. In order that the accumulator or the battery does not discharge itself after the apparatus has been removed from the mains, a switching device is operated when the apparatus is pulled out of the mains socket, which switching device isolates the electrical connection to the accumulator or to the battery. In this way, relatively long storage of the apparatus is also possible without the accumulator or battery discharging.

Patent DE-3510552-A1 (DE)
Title: Weldable plastics mouldings
IPC: B29C57/00
Filed: 1985-03-22
Abstract: Plastics mouldings are proposed which, because of a special design of their leading edges (12, 20) to be welded, are provided with recesses (44, 46) and (48, 50) and welding faces (26) adapted thereto, on the surfaces (28, 36) of which there are attached beads (30, 38), adapted to the groove-like depressions (46, 50), with cross-sections (32, 40) which are adapted to the cross-section of the grooves (46, 50). Channels (34, 42) in the beads (30, 38) permit the plug projecting at the weld edges (12, 20) to flow to the side to a small extent during pressing of the plastics mouldings (12, 18) onto the welding face (26). The plug (12, 20) remaining next to the recesses (44, 46) and (48, 50) is first of all melted under pressure, followed by pressureless heating of the grooves (46, 50) before, after the removal of the weld face (26), the heated parts (10, 18) are pressed against one another and thus the welding takes place. According to the invention it is achieved that a relatively smooth weld seam which is only slightly raised, without the formation of a weld bead, forms in the region of the recesses (44, 46) and (48, 50) after completion of the welding operation. <IMAGE>

Patent DE-3540846-A1 (DE)
Title: Stall outgoing-air cleaning system with heat recovery
Inventor: GAEBKEN HEINRICH
IPC: A01K1/00
Filed: 1985-11-16
Abstract: The stall outgoing air contains, important in this case, heat and odour particles. Both are to be removed to the greatest possible extent. A submerged pump conveys water from the collecting container to an air heater with special steel pipes, and lamellas which, in terms of material, are of less importance. The incoming air for the stall is guided through the air heater (cooler) and is heated. The cooled water is distributed to U-bowls (as illustrated in the drawing) with the aid of a water distribution system. If the U-bowls are filled with water, they overflow at given points. It falls into the bowls which are situated below and which overflow in turn etc. The water thus falls downwards, distributed over a surface, back into the collecting container, where the submerged pump is situated (circuit). The stall outgoing air is guided in the opposite fall direction through the housing with the U-bowls. The air is caused to be distributed by the bowl underside (swirls). As a result of the frequent change in direction and as a result of the distribution of the air, it is made possible that the odour particles situated in the air are absorbed by the water. Small quantities of clean water are constantly brought into the installation via a float valve, as a result of which the dirt layer which forms on the surface of the water in the collecting container can flow off.

Title: Transmission
Inventor: KREDTKE FRIEDHELM
IPC: F16H35/10
Filed: 1985-12-20
Abstract: Variable-ratio transmissions with an overload safeguard in the form of a hydraulic drive are known. The disadvantage of these, however, is that the full force of sudden stresses emanating from the machine can be transmitted via the drive to the transmission and cause damage. In the light of this, the invention now provides a planetary spur-wheel stage 12 on the output side of the transmission 8, the sun wheel 15 of which is connected via a selector clutch 13 to the gearbox input stage 11. The internal wheel 16 of the output stage 12 is supported on the gear case 19 via a torque measuring device 26, it being possible for the selector clutch 13 to be influenced at least indirectly by the torque measuring device 26. In the event of sudden excessive shock load, the torque flow is interrupted at the sun wheel 15, thereby protecting the transmission 8. <IMAGE>
