Title: Transfer of the heat from thermally treated foundry sand to the used sand to be regenerated
Inventor: KEICHEL GERHARD
IPC: B22C5/08
Filed: 1986-12-16
Abstract: The foundry sand reprocessing can be carried out according to the invention in a considerably more economical manner if the heat of the thermally treated sand is used for preheating the sand which is to be regenerated. A single-stage heat exchange via heat exchange surfaces forming vertical honeycomb-like channels or in a rotary pipe cooler with an inner drum and an outer drum is preferred. The interposition of a liquid medium for the heat transfer to a second heat exchanger, in which the cold used foundry sand is preheated, is also possible. While allowing for two specific difficulties, namely the transport of the sand which is to be preheated, and increased wear, considerable quantities of energy can be saved without substantial investment costs and operating material costs. <IMAGE>

Filed: 1987-09-03
Abstract: The invention relates to a wavelength-independent optical digital/analog converter (D/A converter) having an optical fibre, which has optical input and output coupling locations, at which electrical light sources and receivers are arranged. The optical fibre has a relatively high absorption coefficient  alpha , which is constant over its length, as well as a number of optical input coupling locations (the number corresponding to the maximum bit count of a digital word to be transferred), which are distributed along the optical fibre with uniform spacing, n being the base of the digital system (e.g. binary system; n = 2). The electrical light sources n arranged at the input coupling locations have variable intensity levels Pn, including the intensity level P0, each light source being assigned to one bit position of the digital word. The electrical light sources can be activated by n different signals to generate optical pulses. At one end of the optical fibre, at a distance d from the input coupling location corresponding to the first bit position (most significant bit), an optoelectrical detector is arranged for acquiring the intensity maximum of all the optical pulses overlaying one another, at least some of the time, and for forming an analog electrical signal which corresponds to the intensity maximum.

Patent DE-3741127-A1 (DE)
Inventor: REPENNING DETLEV DR
IPC: C23C14/32
Filed: 1987-12-04
Abstract: A process for the production of layers which have great hardness and/or low-friction properties, in particular based on micro- or nanodisperse carbide carbon layers, is proposed. A target material to which an electric potential is applied is converted in a vacuum into a target plasma. The target plasma reaches the substrate which is at an electric potential approximately equal to or higher than that of the target material and forms the desired layer on said substrate. The target material is formed by a titanium alloy, the titanium alloy being vaporised by means of an arc to give a titanium alloy plasma. The conversion of the titanium alloy into the plasma is carried out in the gas phase of ionised carbon. The process is operated by a method in which titanium alloy carbide, gaseous titanium alloy and carbon are formed, the carbide of the titanium alloy, the titanium alloy and carbon being formed, in succession on the substrate, as a ternary layer which additionally has thermal stability.

Filed: 1988-10-12
Abstract: The graphic elements of a document are reproduced on the surface of a workpiece (5) that is machined by focussed electromagnetic radiation (11), in particular laser radiation. In an installation for scanning the document and for machining the surface of the workpiece (5), the document, for example a drawing, is first scanned by electromagnetic radiation and an electronic reproduction of the document is prepared in the control and memory unit (16) that controls the installation. The surface of the workpiece (5) that takes the place of the document is machined according to this electronic reproduction. The same radiation guiding (3, 4) and focussing means (2), controlled by the same programme, are used for scanning and for machining. The machining process can be repeated on a plurality of workpieces (5). Small errors in the reproduction of the optical elements used in the focussing means (2) do not affect the quality of the reproduction. Only simple programmes are required for electronically controlling the installation. It is possible to include various quality control means in this process and in the corresponding devices.

Title: Method of determining optimal nitrogen, potassium and phosphate fertiliser combinations for a quality-orientated production of agricultural produce in crop plants
Inventor: ZHANG WEI-LI DR
IPC: C05G1/00
Filed: 1988-07-25
Abstract: Decisions about fertilising are currently being made with a virtually exclusive view to the yield level desired. These decisions do not take into account the overall interconnection of nutrient availability, their effects on yield and on the content and composition of constituents which determine quality, as well as the interactions of these factors. In the novel method, optimal decisions with regard to fertilising are calculated on the basis of a non-linear optimisation model which reflects this overall interconnection and the dependencies which exist. The user preselects the values desired for the various plant constituents which determine quality. Then, an EDP programme calculates the maximum yield to be expected based on a non-linear optimisation model. The user may then alter the preselected values until the desired ratio of yield and constituents is obtained. Once this ratio is obtained, the optimal NPK fertiliser combination is determined. The effect of N, P and K fertilisation on plant yield and plant constituents.
