Abstract: A photoresist film containing a phosphate of a formalin condensate of diazodiphenylamine, 2,5 - bis (4ʹ - azido - 2ʹ­- sulphobenzylidene) cyclopentanone Na, polyvinylalcohol, and polyvinylpyrrolidone is formed on the inner surface of a faceplate. The photoresist film is hardened by light exposure using a point or linear light source, which is essentially a circular light source, via a shadow mask having a large number of apertures. A light absorbing film is formed on this photoresist film. Then the hardened photoresist film and the light absorbing film on top of it are removed using a peeling agent.

Abstract: In an arrangement which is for use in an electronic circuit controllably put into operation by a battery (20) and which is for indicating a consumption status of the battery, a measuring circuit (22) measures a total time interval of operation of the electronic circuit. A processing circuit (21, 27) processes the total time interval into a calculated status for the battery. An indicator (32) indicates the consumption status based on the calculated status. The processing circuit may comprise a memory (21) for memorizing various current rates which are used in the electronic circuit and on which an arithmetic circuit (27) calculates the calculated status. Alternatively, first and second measuring circuits (25, 26) may be used with first and second current rates memorized in the memory for the first and the second measuring circuits. Instead of the measuring circuits, a summing circuit may be supplied with a succession of the current rates repeatedly read out of the memory to sum up a total amount of consumed current consumed by the electric circuit. As a further alternative, a counter counts down to obtain the total time interval in response to a pulse sequence of a pulse repetition period variable in proportion to a varying level of electric current supplied from the battery to the electronic circuit.

Abstract: A process is used for the extraction of substances contained in milk, vegetable milk and similar liquids and/or from derivatives and/or from recombinates of such liquids. The liquids consist of a solvent and dry substance in polydisperse form. In order to be able to use a process of this type for extracting contained substances in highly pure form with defined properties in an economic manner, the contained substance to be extracted is enriched in its natural biochemical dispersion and/or solution form in the solvent to 45 to below 90% in the dry matter present (first step). Subsequently at least one other contained substance is deliberately changed in terms of content (enrichment or reduction) and/or in terms of activity (activation or inactivation) in such a way that this transforms the existing natural biochemical dispersion and/or solution form of the contained substance to be extracted into another dispersion and/or solution form (second step). The content of the contained substance to be extracted, in the transformed biochemical dispersion and/or solution form, is then further increased by processes known per se (third step).

Abstract: Method for synchronising a clock generated with the aid of a counter with a reference clock. 
<??>So that a reference clock (fR) can also be replaced in case of neeed by another clock (f) without phase shift, the phase in addition to the frequency of the clock (f) must be synchronised with the reference clock. However, since the reference clock can fail or be disturbed, unwanted synchronisation events frequently occur in these cases. It is the object of the invention to produce phase synchronisation between the two clocks which is as free of errors as possible. 
<??>As a rule, synchronisation is therefore only carried out when a particular edge of the reference clock occurs within a time band fixed with respect to the clock (f).

Abstract: In a flushing tank for toilet flushing, having a water outlet which makes a connection with a toilet bowl and is controlled by a flushing valve, the flushing valve reaches, with an extension, through a flushing-water supply situated above the flushing valve. The foul air from the toilet bowl is sucked off by a vacuum generator. Extending through the flushing water is a suction tube which is connected to the vacuum generator and is connected, on one side, to an upper end, remote from the flushing valve, of the extension in the form of a pipe and leads, on the other side, to at least one exhaust fan which receives the foul air sucked off from the toilet bowl. The flushing valve forms with the extension and the suction pipe a discharge fitting which extends through a housing receiving the flushing-water supply and is fixed in an opening leading out of the housing. The opening is provided in a base which closes the housing at the bottom in the vertical direction. To cut off the water, there is provided a discharge connection-piece which is fixed to the base of the housing and forms the lower part of the discharge fitting. The discharge connection-piece is screwed to the base via a sealing system. The suction pipe is guided eccentrically in the region of the discharge connection-piece. An annular valve seat of the flushing valve, which in the closed state of the flushing valve is impinged by an annular valve part, is formed on the discharge connection-piece. The valve part is fixed to a lower end, facing the flushing valve, of the extension. A vacuum generator is connected to the suction pipe. The vacuum generator and its drive are mounted inside the suction pipe. The vacuum generator has a time control. The suction pipe on one side and the extension on the other side are connected to one another via a bell which projects above them at their upper ends and is immersed with its lower edge into a quantity of sealing water which gastightly closes its inner space. The quantity of sealing water is formed by the flushing-water supply.
