Title: Process and apparatus for seawater desalination
Inventor: BASLER MARTIN DIPL ING
IPC: C02F1/14
Filed: 1981-05-16
Abstract: The patent application relates to a process and a corresponding apparatus for seawater desalination, the evaporation with subsequent recondensation of seawater proceeding solely with the utilisation of solar energy. In this case, the air which is to take up the seawater to be evaporated is drawn by suction through a natural stack-draught effect between the water surface and the film serving as a cover. As a result, the air is heated because of the solar radiation with simultaneous increase of the absolute air humidity, caused by the seawater evaporated by solar radiation. This air enriched with moisture is then cooled on surfaces which are situated beneath the water level, the condensate precipitating here and running off into a collector tank, before the air passes into a stack. The air flow is driven by the continuous heating on the path from the stack entrance to the stack outlet, caused by the temperature difference between the seawater and the upper part of the stack heated by solar radiation, because the temperature level overall in the stack is higher than in the surroundings. <IMAGE>

Title: Folding frame for sports and leisure furniture, for example folding chair and folding table
Inventor: SEIDENPFENNIG MONIKA
IPC: A47C9/10
Filed: 1982-05-04
Abstract: In folding frames for sports and leisure furniture, for example folding chairs and folding tables, consisting of two pivoting frames which are mounted on one another in an articulated manner at the centre of their lateral struts connected by cross struts, there is the problem that said pivoting frames do not achieve such stability on uneven and, in particular, inclined terrain that the seat or table surface is aligned horizontally. In order to achieve this, the invention provides for at least one of the two pivoting frames to have a subdivision into a first U-shaped frame part, which comprises a cross strut and the two side struts provided with the pivoting bearings, and a second U-shaped frame part comprising the further cross strut of the pivoting frame, said second frame part being movable on the first U-shaped frame part and being hinged thereto in a lockable manner. The mobility is effected, in particular, by telescopic extension of the second U-shaped frame part. As a result, at least one of the two pivoting frames can be shortened or lengthened so that a folding chair or folding table fitted with the folding frame according to the invention can be set up with a horizontal seat or table surface even on uneven terrain.

Patent DE-3235279-A1 (DE)
Inventor: NOSO KAZUNORI
IPC: G10L25/78
Filed: 1982-09-23
Abstract: A speech recognition system for an automotive vehicle derive a spoken instruction start signal and a spoken instruction end signal when a smoothed spoken instruction signal exceeds or drops below a predetermined threshold level representing the intensity of the background noise for more than first and second predetermined time periods, respectively. Noise is determined by converting the output of a microphone transducing the spoken instruction into a single polarity signal that is smoothed with a long time constant. The single polarity variation is also smoothed with a shorter time constant. The signals with the long and short constants are applied to a comparator that derives a bi-level output signal. In response to transitions in first and second directions of the bi-level signal lasting for first and second durations, the start and end signals are respectively derived.

Title: Internally finned tube for a heating boiler heated by compressed gas or compressed oil
Inventor: HEIM KURT
IPC: F24H9/14
Filed: 1983-01-28
Abstract: The internally finned tube consists of integral casing strips (2) which have multiple fins in the longitudinal direction and are welded together at the longitudinal sides, each casing strip (2) having a side shank (4) on each longitudinal side. The casing strips, cut into lengths from a continuous length, are bent into a circular segment with the desired external diameter of the internally finned tube, so that the mutually adjacent fins (3) converge. So that the side shanks (4) can also be bent as well as possible, their width is widened to the fin spacing at the bottom end of the fins, and each casing strip having e.g. five fins up to this point is then merely provided with four more fins, or one fin less. A fin (7) closing the weld gap is welded from outside, into the weld gap (5) between two casing strips (2) by means of a special pressing apparatus (9), so that two casing strips and likewise the inserted fin (7) are welded together, from outside, in a liquid-tight fashion in one welding step. <IMAGE>

Title: Method and device for compacting bulk material in bags and application
Inventor: HEINZER HANS
IPC: B65B1/22
Filed: 1983-02-03
Abstract: For compacting the filled material, the filled bag (16) held in a shaping chamber (14) is transported onto a jarring table (47). At this point, the sides of the bag are pressed together by a pair of rollers (30a, 30b). With simultaneous vibration on the jarring table (47), the filled material is pressed together by rotation of the rollers (30a, 30b). The packages (P) thereby assume an at least approximately prismatic shape with flat sides. Sealing the aperture with the rollers (30a, 30b) means that the contents cannot be made to spray out by the vibration and the bag sides remain clean, so that the bag can also be sealed by means of a welding operation. <IMAGE>

Title: Process and device for oiling a pneumatically operated, discontinuously working tool, such as a screwing, nailing, riveting tool or the like
Inventor: FEHLINGS JUERGEN
IPC: B23Q11/12
Filed: 1983-02-18
Abstract: The invention relates to a process and a device for oiling a pneumatically operated, discontinuously working tool, such as a screwing, nailing, riveting tool or the like. In the case of known processes, the time for lubricating the tool was determined exclusively from values independent of the time for which the tool had been in service. In order to ensure optimum lubrication of the tools of the said type, it is proposed to measure in each case the flow time of the compressed air, in each case add up the measured times and activate an oiling device after a desired time. The device for carrying out the process is characterised by a flow sensor which is arranged in the compressed-air line and is in a first position when the compressed-air line is closed and in a second position when the compressed-air line is open, a timer which is activated by the flow sensor, measures the period of time for which the compressed-air line is open and adds the periods of the time of the individual opening phases, as well as an oiling device which can be actuated by the timer.
