The reciprocal spacing and cutting depth of the cutters (3) can be adjusted as required and the circular arc-shaped incision in the channels is formed with a special radius plate. The equipment has a chassis (1) to which is connected a rotating shaft (2), along which one or more cutters (3) can be connected with varying spacing between them. The distance between the channels (4) can be varied, as ...

Cellular radio system base stations (10, 12) offer various service levels and transmit control messages (14) indicating said service levels. Terminals (20) store information (22) about previous connections and, based on that information or on their own capability, produce a prediction of the service level required by the next connection. A terminal selects a cell such that the service level in the...

A liquid fuel burner (10) is provided with a central fuel outlet (18) having a g enerally divergent conical inner surface, formed of two contiguous divergent conical surf aces (20a, 20b) of different angles of divergence, and a plurality of oxygen outlets (22) shaped and positioned for creating a converging, rotating stream of oxygen which intersects with any liquid fuel issuing from the fuel outl...

An optical fire detector employs two or more sensors operating a different spectral bands. The spectral bands are selected to have approximately coincident cut-off wavelengths in order to make the detector's ability to positively identi fy a fire more uniform over its field of view. The use of three overlapping spectral bands provides the detector with enhanced detection capabilities for large, ho...

A method of manufacturing substrates for laser diodes and similar opto-electronic devices. The substrates have a bi-level configuration with at least two isolated metal contacts extending continuously between the two surfaces. The method permits mass production of such substrate from a plate of substrate material. A substrate resulting from the method is also described.

The energy collector has a housing with a cover which is transparent to visible and thermal radiation. One or more heat collectors are disposed in the interior of the housing. The heat collectors are carried by a pipe through which a heat-transport medium flows. Each of the collectors is assigned a reflector of concave design underneath the respective heat collector. The width of the reflector is ...
