Title: Measuring active and reactive powers and power factor - using voltage and current sampling and stochastic encoder giving random or pseudo-random pulse probability
Inventor: MASSEN ROBERT DR ING
IPC: G01R21/133
Filed: 1977-03-30
Abstract: The system measuring active-power, reactive-power and power factor for electricity meter applications comprises a sampling stage which samples voltage and current and a stochastic encoder which gives a random or pseudo-random pulse probability. This is fed to a shift register and one-bit register and via a coincidence gate to counters which indicate active and reactive power. The power factor cos phi is determined via further gates and delay stages from which the squares of the active and reactive powers are derived. In a further logic stage normalized addition is carried out. The output of this stage is proportional to the square of the apparent power.

Title: Glass optical waveguide fibre - made from glass tube coated in its bore and collapsed to obtain rod drawn into fibre
Inventor: AULICH HUBERT DR
IPC: C03B37/012
Filed: 1977-07-19
Abstract: The bore of a glass tube is coated with a layer of glass, and then the tube is collapsed to form a rod blank drawn into fibre. The glass is formed by feeding (a mitxt. of) solid powder(s) into the tube, followed by heating the tube so the powder(s) form a molten glass. An inert gas is rpef. fed through the tube during the coating process; and the glass layer is pref. formed by chemical vapour deposition, i.e. by feeding reactive gases through the tube. The tube is pref. rotated on a horizontal axis and zone heated to form the glass layer. Heating pref. results in the escape of any gas bubbles in the glass melt; and the entire tube is pref. heated above the softening temp. of the melt after forming the latter. The powder(s) pref. include a small amt. of oxide(s) which form a glass, and where the cations in the oxide(s) have a higher diffusion speed than the cations in the powder(s) at the melting temp. used for glass layer. The process is cheaper than previous processes.

Title: Hollow profile spacer for insulating glazing frames - rolled from aluminium strip with hooked ribs along rabbeted edges (OE 15.3.79)
Inventor: LISEC PETER
IPC: C03C27/12
Filed: 1978-07-14
Abstract: The free long edges of a strip of metal such as aluminium, which are stepped back to interlock with each other, and form a hollow profile spacer for insulating window panels, are provided with lengthways-running ribs. These have a hooked cross-section, and when engaged with each other, they form a diffusion gas through which the hygroscopic material can act. Viewed in cross section this gap runs in a zigzag. The faces of the ribs turned towards each other subtend acute angle to the opposing faces of the stepped-back zones, and are undulated slightly to keep open the gap. The profiles are produced in one piece by extrusion or rolling, and have among others, the advantages that when sawn off to length, the ends do not out, and side thrust cannot open the profile and cause breakage of the glass.

Filed: 1979-09-11
Abstract: In this measuring apparatus, a sample of the extract to be examined and the chosen solvent, for example compressed carbon dioxide, are converted from the homogeneous phase to the nonhomogeneous phase in a high-pressure cell (1) by changing temperature and pressure. The turbidity occurring at the phase change is detected as a change in the absorption or scattering of the luminous flux between the light source (2) disposed in/at the volume being measured and the light receiver (4). The separation curves determined with the extract concentration as additional parameter can be converted directly into solubility curves. The light source (2) is supplied by a current source (3). A display instrument (6) is controlled by means of an amplifier (5) connected to the output of the light receiver (4). Situated inside the high-pressure cell (1) are a heat source (7) and a thermocouple (8). The pressure-generating medium is applied to the high-pressure cell (1) via (21, 22); the prevailing pressure is indicated on a manometer (10) and can be fed to the display instrument (6) as converted second measured quantity. The measuring apparatus is particularly suitable for determining very low solubilities and for low-volatility, possibly multi-component, extracts of natural substances. <IMAGE>
