Patent DE-3736800-A1 (DE)
Title: Switched mode power supply
Inventor: SCHMIDT KARL DR ING
IPC: H02M3/337
Filed: 1987-10-30
Abstract: In a very simple and cost-effective switching concept for a switched mode power supply, a free-running series-resonant circuit (Cr, Lr) on the primary side of a transformer (TH) controls two switches (S1, S2) which switch over a DC voltage (UB) alternately. A regulator (7), which detects a rectified output voltage (UO) on the secondary side of the transformer (TH), in each case influences only one half-cycle of the oscillation signal of the series-resonant circuit (Cr, Lr). The regulator (7) is synchronised to the relevant regulated half-cycle by means of a signal which is picked off a secondary winding (6) of the transformer (TH). The unbalanced signal waveform on the resonant-circuit capacitor (Cr) in regulated operation leads to a shift in the mean charge on the resonant-circuit capacitor (Cr) and thus to regulation of the power transmitted via the transformer (TH). <IMAGE>

Patent DE-3738971-A1 (DE)
Inventor: PRELLWITZ HUBERT
IPC: A01D59/04
Filed: 1987-11-17
Abstract: A method for tying strands of binding material (2,3, Fig. 1) in a press baler comprises the steps of guiding the strands from a fixing point (4) to a knotting bill (1) so that one strand is arranged above and one below the jaws of the bill, the strands being crossed on the side of the bill remote from the fixing point, in such a manner that the strand (2) extending over the bill is closer to the shank thereof than the strand (3) extending below the bill. The bill is then rotated between the crossed strands (Fig 2). Thereafter the jaws are opened to engage the strand portions coming from the fixing point (4), the jaws are closed, and in further rotation the bill binds the thus formed knot. After the strands have been severed at the fixing point, the knot is stripped off the bill and drawn tight by one of the strands. <IMAGE>

Title: Connection of two ends of gas pipes, inner sleeve for this connection and process for producing this connection
Inventor: PAMPOUKOGLOUS STILIANES
IPC: F16L13/02
Filed: 1988-02-06
Abstract: In the case of known connections, use is made of an outer sleeve 4 which overlaps the two pipe ends and, before the gas-tight welding to the pipe ends, is outwardly sealed by asbestos ropes for the filling of the pipes, e.g. with burnable gas. According to the invention, the use of asbestos, which is a health hazard, is to be avoided. This is achieved by connecting the pipe ends by means of an inner sleeve 3 which is sealed by a sealing material which is not a health hazard. The welding of the pipe ends to the outer sleeve 4 then takes place once the pipes 1 and 2 have been filled with the gas which is to be channelled. The invention is preferably provided for the pipelines for burnable gases. <IMAGE>
Patent DE-3803729-A1 (DE)
Title: Plug-in socket seal for concrete pipes
IPC: F16L17/03
Filed: 1988-02-08
Abstract: In the case of concrete pipes with plug-in socket seals which are already formed in when the pipe is produced, there is the danger, during transportation and storage on a building site, of foreign bodies, such as loose sand, small stones or the like, being deposited in the region where the sealing part butts against the socket wall. The relevant locations thus have to be cleaned carefully before laying the pipes. In order to avoid such work on the building site, the surface (5), of the sealing part (3), embedded in the concrete during the pipe production is anchored in the concrete by a positively locking element (6) which runs in the region of the free edge (4) of the sealing part (3). This results in a smooth-surfaced inner wall which is easy to clean. The positive locking is only released for laying, with the result that the sealing part pivots over into its operating position and the spigot of the following pipe can be enclosed. <IMAGE>

Title: System for raising water to a higher level
Inventor: GOERES HANS DIETER WILHELM
IPC: F04F1/04
Filed: 1988-09-09
Abstract: In order, for high elevation irrigation or for supplying hydrostatic rising mains on hydraulic low-pressure water-circulation piston machines (e.g. Gaetano Salusto and H.D.W. Goeres), to raise water to great heights, optionally also for the use of fall height in the case of turbines, (coupled with vacuum-steam turbines, if desired) the vacuum-vaporised water is sucked up or conducted upwards, and steam is converted back into water through condensation, which sustains suction for the steam arriving later. By use of wind power, a wind-jet fan can additionally aid in the upward suction, if the steam/air mixture is subsequently only used for precipitation of the water in condensation spaces. Condensation cooling can additionally be obtained by upper coupling with refrigerators driven by focused solar heat (with boiler/absorber/phase-change, or continuously). A small suction fan can be installed in the upward steam line. If not all of the system is a closed circuit with always the same water under vacuum, deaerators are used, which prevent the inrush of air by airlocks with fans and by the use of gravitational force (on the above deaerator), without requiring a pump. For vaporising the water under vacuum, focused heat from water-filled plexiglas lenses or parabolic-mirror rows/troughs or collectors or ground-depth heating of the geothermal kind is used.

Patent DE-3914900-A1 (DE)
Inventor: LEPEK ALEXANDER
IPC: G04F5/14
Filed: 1989-05-05
Abstract: Means are provided for maintaining the high accuracy of atomic clocks and frequency standards when these are subjected to mechanical disturbances such as vibrations, accelerations, as well as to temperature changes. The stabilization is effected by using the reaction of the oscillator (11) to such disturbances to adjust the loop-time constant of the clock or frequency standard resulting in a rapid corrective action, restoring the oscillator to its normal frequency. The detector (21) detects changes in the phase output of the phase detector (16) whose output is used to change the time constant T so that it will result in optimum frequency stability under the detected perturbation. This is achieved by including integrater (22) whose time constant may be controlled using detector (21) outputs. <IMAGE>
