A thickening agent comprising polyether derivatives of the general formula: wherein R1 is a substituted or unsubstituted hydrocarbon radical or an alkylphenol radical having 10 or more carbon atoms, n is 10 to 100, m is 0 to 25, and p is 1 to 3, and wherein R2 is an alkyl radical having 8 to 30 carbon atoms. These polyether derivatives are prepared by the gradual addition of a long-cha...

The destruction appts. comprises first and second arrestors which move towards each other to deform a can introduced between them. The second arrestor is connected to a deformation force sensor with an operating component which is adjusted dependent upon a force exerted during the first deformation stage. Where this first stage force is within a predetermined range, the operating component adopts ...

There is disclosed new and improved photovoltaic devices which provide increased short circuit currents and efficiencies over that previously obtainable from prior devices. The disclosed devices include incident radiation directing means for directing at least a portion of the incident light through the active region or regions thereof at angles sufficient to substantially confine the directed rad...

The distributor vessel contains a radiator fluid, a heat exchanger to heat tap-water, a condenser belonging to a heater pump, and a hot gas cooler for the heater pump. Two covers are placed coaxially with the vessel cover. The condenser is situated in the lower part of the channel between the covers, with the gas cooler in the upper part.

The distributor consists of a standing vessel containing radiator fluid, a first heat exchanger which has tap water steaming up through it to be heated, and a second and third heat exchanger which have heated coolant from a heater pump streaming downwards through them. The heat exchangers each have several heat exchange batteries joined in series, being evenly distributed along the vessel's height...

The electron energy spectrum recording system uses a sampling chamber, a radiation source for irradiating the sample to cause its electrons to leave it, and an electron-spectrometer which records the electron energy spectrum. A source with stabilised direct current applies an electrostatic potential gradient in the space between the sample and the outlet gap of the sampling chamber. This gradient ...

Hipsometer comprising an angle indication device 2 for indicating a predetermined angular position between a holder 3 and a part 4 that is moveable in relation to the holder. The moveable part always places itself at a predetermined angular position to the perpendicular. The holder 3 and the moveable part 4 are provided with rasters so that interference patterns, so-called moir' patterns, arise wh...

The storage and workshop unit comprises a conventional container (1) with doors (2,3) at one end. To produce a protected work place connected to the container, a roof-forming part (4) is pivotably attached to one upper container edge. There it can pivot as a continuation of the container roof. - A further section (7) is attached to the outer end of the roof section and can pivot from a position wh...
