Title: Power take-off coupling
Inventor: CONRAD ERNST
IPC: F16D1/10
Filed: 1981-12-24
Abstract: On a power take-off coupling for connecting the input shaft of an implement to the power take-off shaft of a motor vehicle, in particular an agricultural tractor, comprising two interengaging coupling members, one of which is arranged at the end of the power take-off shaft and the other is arranged at the end of the shaft which drives the implement, the object to be achieved is that of providing a rapid-action coupling which is of simple construction, is easy to handle and with which the input shaft of an implement can be connected to the power take-off shaft of a motor vehicle. The invention solves the object by virtue of the fact that one coupling member is a wheel provided with radial driving fingers and the other coupling member is a wheel provided with engaging dogs arranged axially parallel, that a housing in the form of a box-shaped frame surrounding one coupling member is attached to the gearbox housing the power take-off shaft, that a shield in the form of a plate is arranged directly behind the coupling member on the shaft which drives the implement, in which plate the coupling member or a shaft carrying the coupling member is rotatably mounted, and that fixing devices for the shield are provided on the box-shaped frame.

Title: Irrigation plate
Inventor: SLADKY HANS
IPC: F28D3/00
Filed: 1982-07-26
Abstract: A heat-exchanging surface is irrigated by a medium which trickles from a multiplicity of openings onto the heat-exchanging surface. These openings extend from a top side averted from the heat-exchanging surface onto an underside of the irrigation plate facing the heat-exchanging surface. The openings are aligned in the longitudinal direction of the surface around which the medium flows, so that the medium accumulating on the top side flows through it in the direction of the heat-exchanging surface.

Title: Circuit arrangement for generating an echo signal during the reproduction of audio-frequency signals
Inventor: WAGNER DIETER
IPC: H04S5/00
Filed: 1982-08-19
Abstract: In this circuit arrangement, the audio-frequency signal is divided in a filter circuit (13) which exhibits a number of band-pass filters with adjoining pass-band filter ranges (13-1 to 13-5), into component signals which are supplied to loudspeakers (25, 26, 27) tuned to the respective frequency range. Level-determining circuits (31-1 to 31-3) are provided which separately determine the levels of at least some (13-2 to 13-4) of the component signals. These levels are conducted via threshold circuits (59-1, 59-2, 59-3), in each case having an adjustable threshold value, to a comparator (60) which compares them with one another. The component signal having the highest level (13-3) is switched through to an echo circuit (40) in which this switched-through component signal alone is delayed by an adjustable period of time. This signal passes via a level control circuit (45-1, 45-2, 45-3) to at least one further loudspeaker (50, 51). <IMAGE>

Title: Drum sieve
IPC: B28C5/08
Filed: 1982-09-27
Abstract: To obtain high-quality top soil, garden and other organic waste is collected and piled up (compost heap). After approximately a year, the decomposition is extensively complete. This soil must then be sieved and mixed with peat. This manual process is automated with the invention. A conventional conical drum upper part from a concrete or mortar mixer is separated into the container part and the screwing ring (fastening flange). On both sides, a bead is rolled in. At 90 DEG separations, a 400 mm long stay is in each case welded in (see Fig. 2), which reconnects the two parts. The intermediate space created then has a sieve mat laid around it, which is fixed in the beads with a wire stretcher. With the finished device, garden soil of desired fineness and quality can now be produced, as the peat to be mixed in can also be put into the drum. <IMAGE>

Patent DE-3307926-A1 (DE)
Title: Cold-insulated cooling-water pipe
Inventor: VOLLMER GUENTER
IPC: F16L59/18
Filed: 1983-03-05
Abstract: In underground mining, cooling agents are frequently pumped over several hundred metres or kilometres from the production location to atmospheric coolers or similar units, it being intended to prevent cold loss during the transportation by means of effective insulation measures. This is achieved by means of so-called internally-insulated pipes which also prevent cold bridges acting in the connecting regions of the individual cooling water pipes. This and a simple and expedient connecting capability are ensured in that the collar and end disc are of integral construction and are connected to the inner and outer pipe as a structural unit. At the same time, the lower edge of the collar is simultaneously used as a stop surface for the outer pipe, or a corresponding slot is provided in the collar. The collar and end disc form a continuous sealing surface which, for example with a corresponding sealing ring, results in a secure and sealed connection between such cooling water pipes. <IMAGE>

Patent DE-3330005-A1 (DE)
Inventor: LINDNER WOLFGANG DR
IPC: C07C219/20
Filed: 1983-08-19
Abstract: For the analytical and preparative separation of the optical isomers of optically active alkanolamines into their optically pure antipodes a new resolution method is presented which involves an ester formation of the alkanolamines with optically pure and symmetrically O,O disubstituted (R,R)- or (S,S)-tartaric acids. The derivitization reactions are carried out in aprotic solvents and the primary and secondary functions are blocked via ion-pair formations with strong acids, e.g. dichloroacetic acid. The tartaric acid anhydrides are predominantly used as reagents but other ester formation methods are also practicable. The mixture of the diastereomeric alkanolamine tartaric acid monoesters are separable into their optically active and pure isomers by various chromotographic separation techniques, e.g. straight or reverse phase LC, but also by extraction methods e.g. Soxhlet extraction. The optically pure parent alkanolamine isomers can be obtained by ester hydrolysis, with high yield, from the optically pure fractions of the alkanolamine tartaric acid monoesters.
