Title: Windsurfing board
Inventor: SCHMIDTKUNZ KLAUS-JUERGEN
IPC: B63B35/79
Filed: 1982-11-08
Abstract: The invention relates to a windsurfing board with a mast carrying a sail and having a mast foot, which is fastened in the surfboard in such a way as to be movable all round, and a boom which encloses the sail fastened to the mast. For the use of different sail sizes and for adaptation of the rig to the individual sailing situations as well as to the various sizes of the surfers themselves, a mast-foot extension, for example, with clamping foot has become known in which the vertical adjustment is made via a pinch-type screw coupling in which rubber discs are deformed between hard distance rings and the frictional connection is thereby made. An exact, infinitely variable vertical adjustment is thus not possible. The invention proposes a simple vertical adjustment in the form of an infinitely adjustable and lockable mast-foot extension, consisting of a threaded spindle, a nut, arranged in such a way that it can be turned and screwed on the threaded spindle, and also a device on or in the nut with which the nut and thus the rig can be secured in any desired screwed position. In the opinion of the applicant, the idea behind the invention is characterised most clearly by the drawing (Fig. 2). <IMAGE>

Title: Burner with external ignition for pulverulent fuels
Inventor: HUPE ADOLF DR ING
IPC: F23D1/00
Filed: 1982-12-06
Abstract: A burner for pulverulent fuels, in which the burnable dust is ignited in the combustion chamber by the thermal influences of the combustion chamber. There emerges from a central pipe (1) a burnable dust jet with high axial speed and high burnable dust concentration, which flows through a first chamber (6) with a diameter which is enlarged in relation to the central pipe and adjacent thereto a second chamber (7) with a further enlarged diameter. Between the central pipe (1) and the first chamber (6) and between the two chambers (6 and 7), there is provided in each case an annular gap (12 and 13 respectively). Via the two annular gaps, two part air flows are introduced into the two chambers, which are adapted to one another and to the burnable dust jet in such a manner that they separate burnable dust particles from the outer edge zone of the burnable dust jet. The main part of the burnable dust remains in a core jet which is practically unchanged in axial speed and in burnable dust concentration and which emerges at the burner mouth and defines the flame shape. The separated particles and the two part air flows form an ignitable mixture which surrounds the core jet as an annular flow with reduced axial speed and reduced burnable dust concentration and defines the ignition of the flame. Adjustment of the two part air flows and their action on the burnable dust jet can, with the aid of numerous... Original abstract incomplete. <IMAGE>

Title: Electronic device for measuring rotational speed
Inventor: PACHALE UWE DIPL ING
IPC: G01P3/48
Filed: 1982-12-18
Abstract: An electronic device for measuring rotational speed, in particular of internal-combustion engines for vehicles, has, for the purpose of stabilising the device for different motor types, in essence a resettable counter and a frequency divider which is fed from a quartz oscillator and outputs stepped-down counting pulses to a counting input of the counter. Control pulses, for example firing (trigger) pulses are applied to a reset input of the counter. Means for forming averages of the output pulses and displaying the average value are connected to one output of the counter. A second counter output is set up to block the counter. The counter generates output pulses having a width set in accordance with the step-down ratio of the frequency divider, specifically one such output pulse for each occurrence of a control pulse. A second counter, to which inverted control pulses are applied at its resetting input, can be used to double the frequency of the output pulses and to reduce the lower displayable rotational speed. <IMAGE>

Title: Process for the preparation of melamine
Inventor: FROMM DIETER DR
IPC: C07D251/60
Filed: 1983-01-28
Abstract: In a process for the preparation of melamine by catalytic rearrangement of urea, the synthesis gases from which the melamine has already been deposited are treated with urea melts. The treatment is carried out in a scrubber which is provided with cooling elements, the urea melt being introduced both above and below the cooling elements. From the gas mixture, which still contains ammonia and carbon dioxide, treated in this way, the ammonia is preferably absorbed in a solvent with contact times of at most 0.1 seconds and the solvent is regenerated again in two following desorption zones with the recovery of pure ammonia. The bottom temperature in the last desorption step is 105 to 120 DEG C. This temperature is maintained by heating a part of the ammonia to 115 to 135 DEG C in the cooling elements of the scrubber and recycling it to the bottom. The virtually ammonia-free solution drawn off from the bottom is initially used for the scrubbing of the carbon dioxide drawn off from the absorption zone before it is employed therein as a solvent.

Patent DE-3330421-A1 (DE)
Title: Sterile liquid transfer system and associated liquid transfer device with multiple access
Inventor: BOGGS DANIEL R
IPC: A61J1/20
Filed: 1983-08-23
Abstract: A liquid transfer arrangement has a liquid transfer device with multiple access which possesses a number of access openings and two or more connecting elements which can each be connected to a liquid line. Every access opening and every connecting element is normally sealed by a closure against communication with the atmosphere, and this closure can only be removed in connection with an active sterilisation step. The connecting element can be connected to any one of the access openings, the corresponding closures lying against each other. During the active sterilisation step the closures are removed in order to form a sterile, hermetically shut-off liquid path. Since multiple connections can be produced in a sterile manner using the arrangement, the arrangement is very suitable for use in liquid systems of medical processes, for example in hyperalimentation therapy and peritoneal dialysis.

Patent DE-3401219-A1 (DE)
Title: Device for measuring voltage in high-voltage systems
Inventor: KRUEGER MICHAEL
IPC: G01R15/14
Filed: 1984-01-14
Abstract: For this device, a measurement voltage is obtained which represents an image of the alternating high voltage present across the device under test (V), which is virtually a faithful image of the original for all cases of loading. This means that measurement and high voltage have the same phase angle and that the amplitude ratio between high voltage and measurement voltage corresponds to the ratio of the number of turns between high-voltage winding and measuring winding under all load cases, and this over a relatively wide frequency range of, for example, 45 to 65 Hz. In the conductor circuit (4) of the load (V), a complex compensation network (Zk) with active and reactive impedances is located. The complex compensation network (Zk) is designed in its electrical characteristic as a model of the high-voltage switching element, preferably of the high-voltage winding. <IMAGE>

Title: Towing device for lorry trailer vehicles
Inventor: BAUDENBACHER M
IPC: B60D1/42
Filed: 1984-01-19
Abstract: The invention relates to a towing device of lorry trailer vehicles having a drawbar which is arranged on the trailer in a joint via a drawing bogey and a live ring. In order to improve this towing device in such a way that it is possible to use the same towing device for a wide range of towing vehicles with differing heights of the trailer coupling, the invention proposes that the joint of the drawbar be arranged in a drawbar bearing block which is arranged so as to be adjustable into at least two positions on a bogey overhang guided downwards at an angle by the bogey of the trailer, one of which positions being nearer to the bogey and higher than the other. As a result, the bearing block is not only vertically adjustable but also adjustable in terms of its distance from the front axle of the trailer vehicle. Infinite adjustment for widely varying heights of trailer couplings is also possible.

Title: Fluidics component
Inventor: REIF GERHARD
IPC: B01D35/143
Filed: 1984-02-03
Abstract: A fluidics component (20) has a sliding part (31) with a piston (24) and an switching pin (27). During the action of a pressure difference (P1, P2), the piston is displaced, as a result of which the switching pin actuates a switch (36). Upon still further increase in the pressure difference, the piston clears the path from the side of higher pressure to the side of lower pressure. A component of this type serves to transmit a status signal during a first pressure difference below a first absolute pressure and to clear an excess-pressure path during the presence of an even higher pressure difference or a higher absolute pressure. The component can be used in hydraulic circuits or pneumatic circuits. It can be used in excess pressures and vacuums of different magnitude, for which only the dimensioning is to be changed in each case. <IMAGE>
