Title: Working depth control system for vehicle with ground working implement
IPC: A01B67/00
Filed: 1983-03-21
Granted: 1989-06-28
Abstract: A tractor (10) includes a hitch (26) for pulling a ground-working implement. A hydraulic cylinder (34) is extensible and retractable to lower and raise the implement. A control syytem (50) senses operating parameters, including wheel slip, engine speed, draft force and implement or rockshaft position. Error signals are derived from the sensed wheel slip, engine speed and draft force and correspond set point signals. The error signals are combined into a composite or combined error signal. The larger of (a) the combined error signal and (b) a separately determined position error signal. is selected and converted to a pulsewidth modulated valve control signal which is applied to a control valve (42) which then actuates the cylinder to move the implement to reduce the magnitude of the selected error signal. Certain set point signals are derived from the corresponding parameter signals themselves.

Abstract: A method and apparatus for the production of spray deposited ingot, disc or bar is provided in which a spray of gas atomised molten metal or metal alloy particles generated with an atomising device is directed onto a collector. The collector is rotated about an axis of rotation and a controlled amount of heat is extracted from the atomised particles in flight and on deposition. In order to maintain a substantially constant distance between the atomising device and the surface of the deposited metal or metal alloy there is relative movement between the atomising device and the collector. The spray is directed so that the main axis of the spray and the axis of rotation of the collector are inclined at an angle to one another; and the spray is oscillated so that the main axis of the spray oscillates relative to the axis of rotation of the collector. By the method of the invention the shape of deposit is not dependent on the shape or physical containment of the collector ie, for example, a mould as used in a casting process is not required.

Abstract: In order to rationalize the operation of foundries and to avoid environmental stresses, it is endeavored so to rework used molding sand accruing as black sand and to free it from binder residue, so that this sand can be used without restriction like new sand. To achieve this aim through thermo-mechanical regeneration the black sand is heated in predetermined, relative low height layer in a fluidized bed furnace to a temperature exceeding 500 DEG  C., preferably 750 DEG  C. Through the swirling motions of the heated black sand, preferably supported through strong vibrations of the supporting base, the thermal destruction of the enveloping binder particles and a mechanical liberation of the sand grains form their enveloping binder remains is achieved. By means of a forced throughout (e.g. through appropriate vibrations or by means of a scraper conveyor) a uniform throughput with constant layer height is achieved which can be stabilized by means of additionally installed webs so that the desired mode of operation is ensured. By means of pre and post-treatment heat exchangers, the energy requirement can be kept low, while an appropriately high combustion temperature ensures at the same time the creation of environmentally safe oxidation products.
