Title: Apparatus for taking soil samples for agriculture
Inventor: BEHRINGER PAUL DR
IPC: G01N1/08
Filed: 1986-04-12
Abstract: In economic and ecological terms, the examination of soil samples for soil nutrients and harmful organisms is of steadily increasing importance. The extremely work-intensive taking of soil samples by hand, which often involves errors, is to be replaced by a corresponding piece of equipment. The apparatus, which can be suspended on a tractor, has an arm with a tube which is fitted rotatably on a spindle which is at right angles to the direction of travel. On moving over a piece of ground, the tube penetrates at a point at which the ground has already been cut up by a disc, and it takes up earth. By means of a bar, the earth located in the tube is pushed out and is guided, via a chute, into a bucket which has a plastic bag pushed into it. A plurality of buckets are fitted on one turntable, with the result that soil samples can be taken directly one after the other from a plurality of surfaces without the tractor driver having to get out.

Title: Method and device for measuring the average speed of blasting abrasive mixtures
Inventor: HAMANN JOCHEN
IPC: G01F1/74
Filed: 1986-07-03
Abstract: The invention relates to a method and a device for measuring the average speed of blasting abrasive mixtures. The object of the invention, by means of which the influence of non-axially parallel movement of, and difference in speed between, the individual blasting abrasive particles on the measurement result is eliminated, is achieved by means of a method such that a defined mass of pure liquid is weighed into the collecting vessel, the compressed-air line is blown out without blasting abrasive, the temperature in the collecting vessel is measured, blasting abrasive is fed to the nozzle, the removable plate between the nozzle and collecting vessel is removed, and after termination of the blasting abrasive feed the increase in temperature and the increase in mass in the collecting vessel are determined. The device provides that the nozzle is assigned a collecting vessel having an opening centred with respect to the nozzle. It also provides a removable plate between the nozzle and collecting vessel. <IMAGE>
Patent DE-3625273-A1 (DE)
Title: Electrical displacement sensor
Inventor: HAUBNER GEORG
IPC: G01B7/30
Filed: 1986-07-25
Abstract: An electrical displacement sensor (10) with an oscillator (11) for supplying the displacement sensor with a radio-frequency oscillation and with a soft magnetic coil constructed as a helical spring (16) is proposed, the axial length of which can be varied in the axial direction against its restoring force as a function of the displacement to be measured or the position of an adjusting member (12). To achieve an easily analysable measurement signal with a frequency in the kilohertz range, the oscillator (11) is connected to a stationary radio-frequency coil (15) which concentrically surrounds a section of the helical spring (16). Due to the radio-frequency magnetic field (23) which is generated in the radio-frequency coil (15) and through which the helical spring (16) passes, a radio-frequency measurement voltage is induced in the helical spring (16), the amplitude of which, as analysable measurement quantity, changes as a function of the axial length of the restoring spring (16). The converse, feeding the oscillator frequency into the helical spring (16) and picking up the measurement signal across the fixed radio-frequency coil (15), is also possible.

The tensioning bars (4) are attached to a lower distributor (5) which is guided so as to be longitudinally displaceable on the mast, the displacement path of the lower distributor being bounded at the bottom in such a way that, in the lowest position of the lower distributor (5), in which the umbrella is opened out, the tensioning rods (4) are arranged horizontally. <IMAGE>
Patent DE-3712846-A1 (DE)
Inventor: HOFFMAN THOMAS WILLARD
IPC: C21B13/02
Filed: 1987-04-15
Abstract: The invention relates to an improved method and apparatus for forming metallized iron by direct reduction of particulate iron oxide. The spent reduction gas is recycled from the reduction furnace (10) through a cooler- scrubber (34) and a catalytic gas reformer (38). In the cooler scrubber (34), the spent reducing gas interacts with scrub water. Dust having an affinity for sulfur is recovered from the process and added to the scrub water causing sulfur in the spent reducing gas to form solids which precipitate out and are removed as solid waste. Lowering the sulfur content of the spent reducing gas reduces the sulfur contamination of the catalyst and improves the efficiency of the process. <IMAGE>

Title: Connecting device for joining a casing-pipe portion to a counter-flange
Inventor: HUFNAGEL HANS-JOACHIM DIPL ING
IPC: F16L39/00
Filed: 1987-06-05
Abstract: On the connection of casing-pipe portions (1, 1'), whose inner pipe (2, 2') is enamelled to be highly acid-resistant, there is the difficulty of the enamel layer, which extends up to and over a radially inner region (18, 18') on the end sides (17, 17') of the connecting flanges (5, 11), exhibiting a comparatively high thickness tolerance. The invention thus makes provision for the sealing device, provided between the connecting flanges (5, 11), to be subdivided into an inner sealing ring (19) of comparatively high axial compressibility and an outer sealing region which is separate from said sealing ring and ensures the leak-tightness at the transition (8, 8') of the outer casing pipes (4, 4'). <IMAGE>

Abstract: The process for the recovery of solvent from exhaust air of printers, spray-painting shops and other plants with exhaust air extraction operates with a cylindrical upright adsorption vessel which has, concentrically, in the middle an isolate desorption in the form of the conveyor screw. This conveyor screw has a hollow shaft, out of which the hot desorption medium exits in the upper part and into which the desorbed mixture enters in the lower part. This occurs as a result of the screw vanes which are doubled at these positions, which vanes have orifices at the top for exit and at the bottom for entrance.
Patent DE-3720790-A1 (DE)
Title: Door or wall fastening
Inventor: BISBING ROBERT H
IPC: E05C3/04
Filed: 1987-06-24
Abstract: A rotationally actuated bolt of the fastening device of the "lift-and-turn" type is described, with cam activity in the handle, such that, when the handle is moved into a locked position, it exerts a pull on the pawl, in order to press a door or wall against a door or wall frame or its seal, so as to ensure a sealing-off. Jump activity prevents accidental release. An arrangement with a slot and pin prevents the movement of the handle into a locked position, except when the pin and slot are in alignment. Whilst the bolt and the handle are normally rotatable relative to a sleeve in the door or wall which carries the mechanism, the pin and the slot are arranged in such a way that, for a sufficient axial relative movement, they are not capable of moving the handle into a locked position, except when the pawl is positioned by rotation for movement into a locked position.

Abstract: Face-grinding disc for hard materials, which consists of a support body and abrasive coating, in which bronze, copper and cobalt powder are sintered together with diamond grains of between 2 and 1,100  mu m in size, pulverulent abrasive coating being first of all pressed by means of a press plunger which has on its press surface obelisk-shaped teeth arranged in a 3 mm square grid into the shape of a square mesh, then sintered together, with the press plunger at approximately 760@C and at a pressure of approximately 1200 kg/cm<2>, to a third of the initial bulk volume, whereupon a consumed rim of the support body which delimits the filled-in powder and guides the press plunger is machined off at least to below the base level of the abrasive coating and a grid-shaped abrasive coating with a square grid, 1 mm-wide webs at the upper end and obelisk-shaped spaces located between them resulting, the coating volume of which is in a ratio of 2:1 to the space volume.
Patent DE-3725417-A1 (DE)
Title: Valve timing gear for varying the valve opening time
Inventor: BARTSCH RAINER DIPL ING
IPC: F01L1/356
Filed: 1987-07-31
Abstract: The cam (2) is arranged on a ball (12) worked into the drive shaft (1) and operates the valve by way of a tappet (in the drawing, concealed by the ball (12)). Two balls (3), which are seated in corresponding grooves of the cam (2) and of the ball (12), transmit the rotational movement. The centre points of the balls (3) are fixed relative to the cam (2). By means of an axial displacement of the control rod (13), the guide fork (7) swivels the cam (2) about the axis perpendicular to the tappet surface. The sequence of motions corresponds to a universal joint or a similar joint, depending on the position of the grooves (8). The resulting irregularity of the cam angular velocity (@2) can be utilised for stepless variation of the valve opening time. This allows the valve timing to be adjusted to different engine speeds and loads in internal combustion engines. The primary concern is to improve the full load torque/speed curve in order to increase the economy and ecological safety of an engine. <IMAGE>
