Patent DE-2914689-A1 (DE)
Title: Biological effluent treatment drum - with self-spacing plastics sheets for biogenic mat growth
Inventor: STAEHLER THEO
IPC: C02F3/10
Filed: 1979-04-11
Abstract: An aerobic biological system for the treatment of effluents with organic contamination is based on a partly immersed revolving drum which is divided into six sector-shaped cells, each with two subdivisions. The trickling elements to carry a mat of biogenic matter are made of propylene. Each alternate element has a grid of dome-shaped bosses which are pressed out to both sides in turn and act as spacers for the plane mat growth carrying elements. The plate indicates one side wall of the revolving partly immersed sectional drum. Each drum section is filled up by e.g. polypropylene sheets, pref. of corrugated shape. Alternate sheets (30, 32, 34) have bosses of dome shape, pressed out to the right and to the left in a regularly distributed pattern. These act as spacers for the sheets which carry no spacing elements. This simplifies the assembly and the dismantling of the elements which carry the biogenic mat.

Patent DE-3110517-A1 (DE)
Title: Method and circuit arrangement for partially correcting the drawing in colour image reproduction
Inventor: KLIE JUERGEN DR
IPC: H04N1/62
Filed: 1981-03-18
Abstract: The invention relates to a method for improving the drawing in colour image reproduction by means of partial electronic retouching. The colour values, of the individual colour separations, obtained by image point-wise, trichromatic colour image scanning and digitalization, are deposited in a memory medium. To improve the drawing, the colour values of one colour separation are altered image point-wise by selectable fractions of the colour values, allocated image point-wise, of at least one other colour separation. The fractions of the colour values represent in each case the smallest amount of alteration for the colour values of the colour separation which is to be partially retouched. For each colour value, which is to be retouched, of an image point, which is marked by the retoucher by means of the coordinate pin of a coordinate sensor instrument, a retouching factor is determined which indicates the retouching intensity as the number of the amounts of alteration to be added per image point. Location-dependent correction values for the colour values of the colour separation to be retouched are calculated from the amounts of alteration and the retouching factors. For visual control, the unretouched or retouched image is shown on a monitor.
Patent DE-3118696-A1 (DE)
Title: Micro spirit level for accurate measurements of inclination and adjustments
Inventor: REIF FRIEDRICH
IPC: G01C9/24
Filed: 1981-05-12
Abstract: As a rule, spirit levels which are used for horizontal and vertical measuring and aligning consist of a rod-shaped housing having two bubble levels for the horizontal and vertical measurement. Technically extended devices are also equipped with rotatable angle-of- inclination bubble levels. However, the measuring accuracy - scale resolution/readability - of these measuring tools is unsatisfactory and inadequate for accurate measurements. A further disadvantage are the frequently unintended maladjustment due to a change in position of the bubble level elements which in most cases are screwed in. This invention counteracts these defects by the fact that the elongated segment-area bubble level (6) of different segment shape in radius and arc length and integrated as indentation in the spirit level body (10) consisting of transparent plastic and which is provided with the pin (8) for stiffening and is closed with the cover (9) which is also transparent and is welded over its area, corresponds to the curvature of two large and oppositely directed circular arcs with the scales (4 and 7). For course measurements, the full-circle and box bubble level (5) is also allocated to this micro spirit level. At the same time, the invention provides to insert a sphere as rolling reading marker in the bubble levels as an alternative. <IMAGE>

Patent DE-3124070-A1 (DE)
Title: Continuously variable transmission
Inventor: TOMLINSON MALCOLM
IPC: F16H37/08
Filed: 1981-06-11
Abstract: The continuously variable transmission (Fig. 1) consists of a mechanical variator (10) with three planetary gear sets (12, 14, 16) connected to its output, between an input shaft (18) and an output shaft (20). The design and the transmission ratios of the planetary gear sets are chosen so that the range of transmission ratios of the transmission is considerably larger than that of the mechanical variator, which has a limit of, for example, 6 : 1. The invention approximately doubles this range for the transmission. During the regulation of the transmission ratio, one of the planet carriers (36) is used to feed torque back to the input (22) of the variator. A direct drive between the input and the output shaft can additionally be provided, for which purpose an arbitrarily actuable lock-up clutch is provided between them. In this condition, internal losses and wear can be reduced by fixing one element (48) by means of a selectively operable brake (47). As variators, use can be made of any known designs which allow a suitable configuration of the transmission for the particular application, especially as regards the relative position of the input shaft and the output shaft. Belt drives with a continuously variable transmission ratio are advantageous as variators for vehicle transmissions. <IMAGE>

Patent DE-3127274-A1 (DE)
Title: Grinding machine
Inventor: WANNERT MICHAEL
IPC: B24B55/04
Filed: 1981-07-10
Abstract: The invention relates to a grinding machine for grinding drills, lathe tools, etc. The disadvantage with these has been that the light from the ceiling-lighting system reflected into the protective goggles and small stock for grinding was difficult to see. In practice, this led to the situation, in particular in the case of inexperienced apprentices, where the protective goggles were partially removed to aid vision and eye injuries resulted. The object of the invention is to avoid injuries reliably. The solution is characterised in that the tool-bearing means (5) is lit in conjunction with a collective lens (6) and a concave mirror (8), it being possible for the concave mirror to light the right-hand side or left-hand side by a rotary knob (9), and the motor being inevitably switched on or off. For better vision, two Fresnel lenses which can be turned down are located over the protective goggles. If these are raised, the cam (4) interrupts the contacts and the motor stops. Good vision when grinding small objects and complete prevention of eye injuries, which occurred again and again in particular in the case of inexperienced apprentices, school pupils and DIY enthusiasts, are of advantage. <IMAGE>
