Patent EP-0068449-B1 (EP)
IPC: E02B8/02
Filed: 1982-06-24
Granted: 1985-07-24
Abstract: In order to clean a screen in a waste water purification plant a surge of a body of water is generated by the agency of a dump flushing apparatus, which surge drops in a free fall towards the screen to be cleaned. This surge of cleaning water is given a dimensional extent which ensures for a substantially simultaneous impinging of the body of water onto the total extent of the screen. A framing which surrounds the screen encompasses this surge of water such as to guide the water and to force the water to flow through the screen. During the cleaning or flushing action the contaminants adhering to the screen, which contaminants are substantially of a thixotropic nature, will be removed from the screen and flushed through a sump towards the water purification section of the water purification plant.

Abstract: 1. A method of defrosting an evaporator of a refrigerating machine which operates as a heat pump, comprising the following features : a) after each heating operation, a defrosting process is started, the end of which is determined by the instantaneous value of a variable of state ; b) after each defrosting process a new heating operation is started, the duration of which is determined by a linearly multiplied, positive difference between a defrosting time to be established, and the last defrosting time in each case ; c) below a predetermined instantaneous value of the external temperature, the heating operation time which in each case follows a defrosting process, is determined by the heating operation time which has preceded the defrosting process plus a time value which is calculated from the difference between the last but one and the last defrosting time, linearly multiplied by a positive amplification factor ; d) after a preceding heating operation, each defrosting process is terminated when a variable of state of the refrigerating medium reaches the predetermined instantaneous value in the evaporator ; e) above the predetermined instantaneous value of the external temperature, a defrosting process is initiated if the ratio of running time to shut-down time of the heat pump exceeds a predetermined value, for example 2:1 ; f) the time of the heating operation is limited by a minimum value and a maximum value ; g) the defrosting process is broken off and a switch-over takes place to the minimum heating time when, at the end of a preset time, for example seven minutes, the predetermined instantaneous value of the variable of state of the refrigerating medium contained in the evaporator has not been reached.

Abstract: Un convertisseur CC-CC convertit une tension continue non stabilisée d'arrivée en trois tensions continues stabilisées de sortie. Le convertisseur contient deux étages hâcheurs (1, 2) avec des transformateurs, des redresseurs (3, 4, 17a, 17b) et des filtres de lissage (5, 6, 18) associés. Les deux étages à hâcheurs produisent une première et une deuxième tensions de sortie en forme d'impulsions (Ua et Ub), qui sont régulées en déphasant le bord d'attaque des impulsions dans la première tension de sortie (Ua), tandis que la deuxième tension de sortie (Ub) est régulée en déphasant le bord de fuite des impulsions. Deux tensions de sortie (U1, U2) sont obtenues après redressage et lissage. La troisième tension de sortie est obtenue en reliant en parallèle les sorties de deux redresseurs d'ondes pleines (17a, 17b) qui sont magnétiquement couplées aux sorties des deux étages hâcheurs, et en reliant un filtre de lissage (18) à la sortie commune des deux redresseurs d'ondes pleines. La régulation de la troisième tension de sortie (U3) est obtenue en faisant varier la position de phase (f) entre la première et la deuxième tensions de sortie du hâcheur (Ua, Ub).

Abstract: Oligomeric and/or polymeric radiation-sensitive polyimide and polyisoindoloquinazoline dione precursors which are soluble in organic solvents, and are of high purity, i.e. in particular chloride-free, are produced simply by first reacting an aromatic and/or heterocyclic tetracarboxylic acid dianhydride with an olefinically unsaturated alcohol to an olefinically unsaturated tetracarboxylic acid diester, and then reacting the latter, in the presence of a carbodiimide, with a diamino compound or a diamino compound having at least one ortho-positioned amino group. The radiation-sensitive precursors thus produced are suitable, for instance, for the production of highly heat-resistant relief structures.

Abstract: A hydraulic adjustment motor containing a piston-and-cylinder unit is provided at the roll surface of a roll to be moved to position the roll surface relative to another roll surface of a further roll. Each adjustment motor is arranged between the related roll surface to be moved and its related roll stand. A regulation device is arranged between a pressure source, the pressure chamber of the adjustment motor and a hydraulic medium vessel. This regulation device regulates impingement of the pressure chamber with different pressures up to the maximum pressure of the pressure source and regulates the outflow of a selected volume of the hydraulic medium out of the pressure chamber, correlated to the desired lowering of each roll surface, during lowering of the roll surface and for maintaining a residual volume of the hydraulic medium. Consequently, there is provided a defined relative position between the roll surfaces. This apparatus allows raising, relieving, lowering or holding of the work surfaces of the rolls in desired positions. The apparatus is suitable for rapidly moving apart individual rolls, such as intermediate rolls of the roll stack. By setting an appropriately reduced pressure in the pressure chamber the apparatus can take-up the weights to be relieved, for instance the overhanging or cantilever weights or marginal loads at the individual roll surfaces and to counteract the same.
