Patent DE-3732887-A1 (DE)
Title: Grass-verge mower
Inventor: GILBERS KARL
IPC: A01D34/86
Filed: 1987-09-30
Abstract: The mowing of grass verges on roads and motorways is carried out by grass-verge mowers which can be used only to a limited extent or not at all in the region where trees, traffic signs and the like are standing. In known swing-back grass-verge mowers, very sharp contact occurs between the grass-verge mower and the obstacle, and this can lead to the destruction of the obstacle and restricts the operating speed of the grass-verge mower. There is proposed a grass-verge mower which, by means of an actuating device, ensures that, in the event of contact with an obstacle, the actual mowing unit is positively retracted and, after it is clear of the obstacle, is displaced forwards again positively, so that damage to the obstacles can no longer occur and the swing-out and swing-in movement of the mowing unit takes place very quickly, if appropriate in dependence on the driving speed of the vehicle or of the mowing unit.

Title: Stretchable hose for the reduction of pressure pulsations
Inventor: WARNECKE ROLF DIPL ING
IPC: F16L11/12
Filed: 1988-03-19
Abstract: Known stretchable hoses for the reduction of pressure pulsations and humming noises occurring in hydraulic circuits have a flexible outer pressure hose composed of flexible material and a flexible inner hose which is arranged inside this pressure hose and is connected at one end directly to the inlet of the stretchable hose and, with its open other end, opens freely into the inside of the outer pressure hose. Pressure pulsations etc. which occur are damped with varying degrees of efficiency by the known stretchable hoses depending on the ambient temperature and the operating temperature. In order to guarantee good, as uniform as possible pulsation and noise reduction, irrespective of the ambient temperature and the operating temperature, the flexible inner hose of the new stretchable hose is designed as a metallic spirally wound hose with axially abutting or partially overlapping spring-elastic turns, these being arranged and dimensioned in such a way that, during operation, they lift off one another to a greater or lesser extent, depending on the effective pressure, under the action of a pressure difference arising internally along the length of the inner hose, causing the inner hose to lengthen. The stretchable hose can be used with particular advantage in a hydraulic servo-assisted steering system of a motor vehicle. <IMAGE>

Title: Walking-beam conveying apparatus
Inventor: PUEHRINGER WILHELM
IPC: B65G25/02
Filed: 1988-08-30
Abstract: The invention relates to the stepwise transverse transport of elongate material (28) to be conveyed, for example extruded light metal profile sections, with the aid of vertically and transversely adjustable walking beams (1, 9). While, in the case of the prior art, the material (28) to be conveyed must be raised and lowered during the conveying stroke, the invention proposes, for the purpose of avoiding harmful influences on the material (28) to be conveyed, the use of systems of walking beams (1, 9) which can be moved in a manner periodically offset with respect to each other and which are raised and lowered by means of their pivoting drives (3, 10) in such a manner that the material (28) to be conveyed is always situated on a walking beam system (1, 9) located in the high position and is moved forwards by the latter in the conveying direction (28). For this purpose, the walking beams (1, 9) are guided so as to be capable of being moved back and forth in the conveying direction (28) on their pivoting drives (3, 10). <IMAGE>

Title: Safety door fastening for laundry (tumble) driers
Inventor: HENNINGER ALFRED DIPL ING
IPC: D06F58/04
Filed: 1988-10-06
Abstract: The doors of laundry driers having extremely large loading apertures must be capable of being opened from inside for the protection of small children. Moreover, after the door has been closed, the drum should be capable of being started only by means of a separate switch. Laundry driers of conventional design having small loading apertures possess merely a door-opener button with an automatic drum stop. In the door mechanism according to the invention, by pressure from the inside on the filter cover (2) of the lint filter a closing piston (6) is rotated out of its closing position into the opening position via an actuating tappet (3) and a rope pull (5), so that the door (1) is opened automatically and abruptly by means of the pressure of its gasket. The safety door fastening can be used in laundry driers which work both on the condensation principle and on the exhaust-air principle. <IMAGE>

Title: Process and apparatus for recovering CO by fractionation of an H2/CO raw gas mixture by means of multistage partial condensation
Inventor: FABIAN RAINER DIPL ING
IPC: C01B32/40
Filed: 1988-11-11
Abstract: To recover CO by fractionation of an H2/CO raw gas mixture, this is subjected to multistage partial condensation and each time subjected to phase separation in separators. The liquid CO product fraction formed in the last stage is, after being vaporised to give the CO product, separated into two substreams of which one is recirculated and injected into the CO product fraction collecting in the separator. The associated warming of the fraction causes outgassing of amounts of H2 still present. The residual gas fraction containing H2 and CO which is thus formed can, to recover the CO, be again mixed into the H2/CO raw gas mixture to be fractionated.

Title: Device for optically signalling in road traffic
Inventor: MARX PETER
IPC: G09F9/307
Filed: 1988-12-22
Abstract: The invention relates to a device for optically signalling in road traffic by means of a direction board which has a guide arrow. According to the invention it is provided to activate optically the guide arrow on direction boards by means of lamps, the lamps being constructed as light-emitting diodes, and the current being supplied by a solar unit. Depending on the requirements, the direction board can be set up on its own or combined to form a guide device comprising a plurality of direction boards arranged one behind the other, for example for bends, roadworks or cross-overs. The advantages of the invention in particular consist in that a traffic-safe device was created which can be seen from a great distance and displays actively, which, despite the relatively large number of loads, has a considerably lower current consumption than conventional systems which use incandescent lamps which consume a lot of power. In addition, the invention requires considerably less outlay and servicing than corresponding mains supply or battery supply due to the use of a mains-independent solar unit.

Patent DE-3904716-A1 (DE)
Title: Piston compressor and/or internal-combustion piston engine without a crankshaft, the piston being driven by an eccentric
Inventor: SCHILLER HEINRICH
IPC: F01B9/02
Filed: 1989-02-16
Abstract: In the case of internal-combustion piston engines the piston -connecting rod - crank principle has become predominant. The static and sliding friction caused by the piston, connecting-rod and crankshaft mountings result in considerable frictional losses. In contrast, rolling friction operates in a virtually frictionless manner. The object was to find a solution in order to be able to use rolling-friction bearings without increasing the size and costs of the construction. The solution to the object:     1. the crank is replaced by an eccentric, 2. the connecting rod is shortened in such a manner that there is no longer any rod between its bolt holes and the holes in the eccentric,   3. the piston rod is connected fixedly to the piston and is guided by roller-mounted rollers of the rod-guiding means. By these means the principle of rod - connecting rod - eccentric is formed. Fig. 2 shows a two-stroke engine with the eccentric drive. With this principle of construction the reciprocating piston motion in the cylinder is converted into the rotary motion of the shaft by the rod, connecting rod and eccentrics. The advantages: low frictional losses, no piston wear and only slight cylinder wear.
