Abstract: A system for displaying three dimensional surface structures employs the analysis of voxel elements defined by eight cubically adjacent grid locations which are associated with at least one physical property defined throughout a three dimensional body. The physical property measurements may be made with such systems as computerized tomographic x-ray systems, or magnetic resonance imaging devices. Surface structures are defined by a user selected threshold value such as distinct values for skin and bone In medical diagnostic applications. Selected voxels are subdivided and means are provided for generating signal values associated with intermediate additional grid locations. Means are also provided for generating surface normal vectors associated with these grid locations. The system of the present invention produces a sequence of signals representative of grid locations throughout the object being investigated together with associated surface normal vectors at these locations, the locations lying on a user selected surface. The system provides smooth, high resolution images which are particularly useful for medical diagnostic applications and is particularly useful with conventional display processor hardware used for electronic graphics display. The capabilities of the system additionally provide enhanced flexibility and speed for the convenience of interactive users.

Abstract: A large-surface electro-optical indicator (1) with liquid crystal information representation, in particular in an embodiment for vehicle dashboard panels, is to be designed so as to be capable of production in a cost-effective and technically non-sensitive manner using mass production even when only comparatively few display positions are to be accommodated within a display area which is large for stylistic reasons. For this purpose, individual relatively small liquid crystal cells (2) produced using conventional technology are arranged behind a homogeneous plastic cover pane (3), which faces the viewer, covers the entire display surface of the indicator (1) and is antireflection- coated at the front; by contrast, the remaining region (4) of the cover pane (3) can be printed taking account of symbols for the representation of permanent signs and for graphics supporting the design. The cells (2) are expediently mounted behind the transparent window regions (5) of the cover pane (3), keeping an air gap (11) (that is to say without direct optical coupling); in this case, reflections at the visible side of the cell surface (12) are sufficiently damped due to the fact that the cell analyser (9) is not arranged on the cell surface (12) itself but is bonded as a polarising film directly to the rear (10) of the cover pane. <IMAGE>

Abstract: The conductivity of the outer surface of skin (2) is enhanced by providing an outer layer of conductive material. The outer surfaces of each external metal fastener (8) and the skin around it are covered with a patch (6) of a strongly dielectric material. Patch (6) is dimensioned to cause current flow from lightning strikes to diffuse to a current density belowan arcing threshold before reaching fastener (8). Preferably, further protection against arcing between the outer surface of skin (2) and metallic fasteners and fittings is provided by coating with a dielectric any surface portions of such fasteners and fittings that contact the skin (2) or an integral continuation thereof. When load requirements permit, fasteners made from dielectric materials are used instead of dielectric coated fasteners.

Abstract: The sleeve is a multilayered shrinkable sleeve of plastic for sheathing substrates. This involves fixing the previously widened sleeve on the substrate to be sheathed by at least one of its layers reverting in shape due to its elastic memory. The invention is characterised in that one layer of the sleeve consists of foamed plastic material, whereas the other layer of the sleeve is formed by a compact plastic material. The two layers have been firmly bonded to each other throughout over the entire circumference of the sleeve and widened with each other in the thus-created bond.

Abstract: For composting solid and liquid organic waste, in particular solid vegetable waste, animal dung, liquid manure, sewage sludge or the like by aerobic fermentation with addition of air or oxygen to obtain reutilisable solid fertilisers, the solid or liquid organic waste is mixed at intervals and air or oxygen is added during the mixing. The mixing and aeration is carried out by means of a belt elevator which has at least one conveyor belt turned by means of a driving device, on whose outer belt surface carriers sticking out from this are arranged. The belt elevator is driven by the waste mixture and tears up parts of the waste mixture using the carriers so that these parts can be aerated in the upper section, provided with additives and thoroughly swelled up. Owing to the optimum aeration and swelling up, anaerobic regions within the rotting material are avoided and the rotting time is considerably reduced. <IMAGE>

Abstract: A light valve of the Schlieren dark field type is provided with a vacuum envelope containing an electron gun, a focus and deflection assembly and a rotating disk coated with a light modulating fluid on which an electron beam from the electron gun is scanned in a raster pattern. The rotating disk has a transparent electrode which serves as an electron beam landing electrode. Between the focus and deflection assembly and the rotating disk is a drift ring assembly comprising at least two axially separated segments. The drift ring segment closest to the focus and deflection assembly is operated at a voltage to generate, in combination with the focus and deflection assembly, an electrostatic lens which corrects distortions that originate from deflection fields applied to the focus and deflection assembly. The other drift ring segment is operated at a voltage different from that of the first drift ring segment such that the two drift rings interact to generate an electrostatic lens that controls the focus of the electron beam. The second drift ring and the electrode on the rotating disk interact to generate a third electrostatic lens to further control beam size to an essentially uniform value by further shaping of the locus of deflected field focus to closely approximate the planar surface of the control layer.

Abstract: A DC to DC power converter having reduced switching loss for operation at high frequencies. As disclosed, a buck, or forward, converter includes a first FET (31) as the switching device in series with an inductor (33) and a second FET (32) as the flywheel device. At the common node to which the two FET's and the inductor are connected, there is sufficient capacitance that the FET's may be turned off without appreciable voltage change across the FET's. The value of the inductor (33) is chosen, with respect to the input and output voltages and frequencies of operation involved, to insure that the inductor current polarity reverses each cycle, raising the node voltage to the level of the input voltage, substantially eliminating turn-on losses of the first FET. Control circuitry (40) is provided for regulation of the power converter to control the peak-to-peak current in the inductor and to insure that at least a selected minimum value of the inductor current is present for each cycle of operation of the converter. An over-voltage protection circuit for the output of the converter is also provided.
