Patent DE-3635925-A1 (DE)
Title: Worm-type mower
Inventor: WIENEKE FRANZ PROF DR ING
IPC: A01F29/12
Filed: 1986-10-22
Abstract: Mowing with a rotating worm is unsatisfactory because of the low cutting quality and cleanness of the cut. Furthermore, a high circumferential speed of the mowing units is necessary. The disadvantages are eliminated by providing the worm circumference with an axially parallel and stepped cutting edge. The pitch angle of the worm is below the friction angle, so that an axial conveyance of the mown material is possible.
Patent DE-3641801-A1 (DE)
Title: Energy-saving hydraulic feed device for motor vehicles
Inventor: SCHOPF WALTER
IPC: F16H61/00
Filed: 1986-12-06
Abstract: The subject of the present invention relates to a hydraulic feed device by means of fixed displacement pumps and accumulators, which from economic standpoints is suited to the hydraulic feed requirements of CVT gearboxes and automatic gearboxes. The excess delivery quantities unially occurring in the upper operating speed ranges with fixed delivery pumps designed for the lowest operating speed ranges and the resulting losses are avoided in that, in excess delivery operating ranges, the pump is exposed to the operating pressures or accumulator pressures only intermittently in accumulator charging phases. An essential feature of the invention and a useful effect thereby obtainable lies in the fact that a charging pressure control is arranged, which meters the charging pressure as a function of the consumer pressure, so that control and restriction losses, which conventionally occur when supplying consumers from accumulators with a significantly higher charge pressure level, are prevented or reduced. To a large extent therefore, only that output required for consumers under operating pressure is demanded of the pump drive.

Title: Apparatus for use in the transport of bulk material by means of large-capacity transport vehicles
IPC: B65G67/24
Filed: 1987-01-28
Abstract: During loading of bulk material, such as gravel, quarry rock or the like, an intermediate silo in the form of a slide (3), which is mounted on a framework in the manner of a rocker about a transversely running axis (4) and the bottom of which is formed from a bar grid of longitudinally running bars, is proposed. The slide is bent about the swivelling axis (4) through an acute angle and mounted outside its centre of gravity in such a manner that it permits, under the action of its own weight, the feeding of material for intermediate storage, while, when fully loaded, it can be emptied automatically over its length by tilting about the swivelling axis (4). By this means, as well as a decisive reduction in stoppage time of the transport vehicle to be loaded, which is loaded without interruption, a possibility is created at the same time of separating out the undesired lower grain sizes right at the removal point of the bulk material and thus of sparing the detour through crushing and sorting plant for a large part of the material mined. <IMAGE>

As a result of the invention, automatic operation of such apparatuses is achieved in that the turning device (W) is equipped with a horizontally movable linkage (4) which can be coupled to a turning drive (WA) fixed to the fat trough (21). The turning drive includes a threaded spindle (23) and a nut (22) which is movable along the spindle (23) and to which a carrier (20) is fixed, which, when the immersion frame (R) is lifted out of the trough (21), is coupled (19) to the linkage or to a lever (18) fixed thereto. <IMAGE>
Patent DE-3709463-A1 (DE)
Title: Process for separating off the group of rare earth elements, scandium and yttrium
Inventor: ZACHMANN DIETER DR
IPC: C01F17/00
Filed: 1987-03-23
Abstract: To increase the yield of elements of the group of rare earths (REE), scandium and yttrium in their separation from extraneous elements as a preliminary stage in the preparation of pure REEs, Sc and Y in the chemical industry, two different exchange resins which complement one another in their separation characteristics, are introduced into a separation column. Besides increasing the yield, the simultaneous use of the two resins makes the process largely independent of the sample composition and it can therefore be used as a flexible standard process for separating REEs from many different matrices. In addition, it is possible to separate off all usual extraneous elements in a single process step, without different separation columns having to be used.

Patent DE-3809108-A1 (DE)
Inventor: GERARDS HANS DIPL ING
IPC: G01F1/698
Filed: 1988-03-18
Abstract: In a device for gas flow measurement, especially for air mass flow measurement in motor vehicles with internal combustion engines, having, in series with a measuring resistor (RM), a temperature-dependent gas flow resistor (RL), e.g. a hot-film sensor, around which the gas flow passes, and having an electrical supply source (10) for feeding the series circuit and for heating the gas flow resistor to the operating temperature range, the voltage present at the resistor junction being indicative of the gas flow, there is the problem that the gas flow resistor (RL) must first be brought up to operating temperature, before the gas flow can be reliably sensed. Accordingly, to achieve rapid operational use, the gas flow resistor (RL) is initially heated rapidly to temperature above the operating temperature, followed by cooling caused by the gas flow to the operating temperature with subsequent operational use of the measurement. Numerous ways of pre-heating the resistor (RL) are described. <IMAGE>
