Title: DC inner resistance measuring circuit for watch batteries - discharges battery during short pulse duration via resistor and integrates voltage drop at battery over measuring period
Inventor: MUNZ SIEGFRIED
IPC: G01R31/36
Filed: 1978-07-07
Abstract: The measuring system is applicable to both primary and secondary batteries of small charge capacity. In the process the battery is discharged via a register during a short period pulse duration. The voltage drop at the battery during several such impulse measurements is integrated over the measuring time period of an indication instrument. Preferably the voltage drop is fed via a capacitor to an amplifier during the pulse duration, a rectifier being in series connected behind the amplifier. Typically a moving coil meter serves as indicating instrument. The circuit for this measuring process contains a rectangular wave generator at the control input of a transistor, whose low circuit contains a resistor and the tested battery.

Title: Luminosity meter with brightness response of human eye - uses photometric sphere with internal filter coating with graded reflection factors
Inventor: BLAZEK VLADIMIR DIPL ING
IPC: G01J1/04
Filed: 1978-08-10
Abstract: The lux meter measuring head is in the form of a modified Ulbricht sphere and comprises two sections (1, 2) each with a hemispherical inner surface which is coated with a selectively reflective layer (3). The light being measured enters through a window (4) and through multiple reflection is diffused and filtered by the action of the coloured layer on the inside of the sphere. A screen (5) projecting from teh wall of the sphere ensures that no incident light falls directly onto the window (6) of a photo-detector (7). The reflection factor of the coloured layer is matched to the spectral sensitivity of the photo-detector so that the measuring head has the desired filter characteristics to exhibit a brightness response corresponding to that of the human eye.

Title: Polymer microcapsules prodn. - by adding an emulsion of polymer solution to a miscible non-solvent for the polymer
Inventor: ELFERT KLAUS DR
IPC: B41M5/165
Filed: 1979-07-26
Abstract: New process is claimed for prodn. of microcapsules by emulsifying a solution of a film-forming polymer and of the substance to be encapsulated in a liq. medium with which it is immiscible, and treating the emulsion with a liq. which does not dissolve the polymer but is miscible with the solvent. In the new process, the ratio of non-solvent liquid to emulsion is 1:1 to 10:1 v/v, and the emulsion is slowly added to the non-solvent liquid. Used for microencapsulation of substances such as pharmaceuticals, plant protection agents, microbial cells, adsorbents, pigments and dyes. The process can be used e.g. for the prodn. of prolonged release formulations of plant protection agents or for the immobilisation of enzymes. The new process reverses the procedure of DE 2264074 (addition of non-solvent to emulsion) and thus minimises problems such as flocculation of the polymer and clumping of the microcapsules.

Patent DE-2943366-A1 (DE)
Inventor: STIFTER GUSTAV
IPC: E04H4/06
Filed: 1979-10-26
Abstract: The lowerable covering (1) for liquid basins, in particular swimming pools (3), comprises flexurally rigid hollow profiles (12 to 15) which consist of plastic and have cavities (11) in an extension direction of the pool (3). A plurality of hollow profiles are connected to one another in an articulated manner in the same extension direction. The supply or discharge of air takes place at one end (16) of the covering, while, at the other end of the pool, water is discharged or supplied into the cavities of the hollow profiles. In the case of air-containing cavities, the covering floats on the water in the pool (3), whereas, in the case of water-containing cavities, the covering is located on the base of the swimming pool. Owing to the articulated connection, surfacing or lowering gradually takes place in stages from one end to the other end, such that shooting-out of the covering during lowering or surfacing is avoided without having to provide special guide devices at the edges of the pool and of the covering. By choosing a suitable material and colour, heat insulation, on the one hand, and the possibility of walking on the covering, on the other hand, can be additionally achieved. <IMAGE>
