Title: Failure monitoring circuit for doppler radar and sonar apparatus - uses evaluating circuit for comparison of actual and optimum vehicle, speeds, with failure light and control signal applying correction
Inventor: MUELLER KARL HEINZ ING GRAD
IPC: G01S7/40
Filed: 1980-04-28
Abstract: The Doppler unit is used for the braking control of goods wagons and consists of an antenna connected to a transmitter/receiver whose receiving section has an evaluation circuit with digital filter connected to it. The Doppler oscillation at the output of the filter is fed to an amplitude detector whose output is then passed to a timing circuit feeding a warning light and conductor (7) carrying the failure signal which applies full braking should it be required. A pulse train proportional to the Doppler frequency is fed to a computer, which evaluates the true speed of the goods wagon, and compares it with the optimum speed which is based on the wagon weight, frictional losses, axle count etc. applying the brakes until both speed values coincide. If the Doppler signal disappears from the output (28) of the evaluating circuit, a signal is applied to the timing circuit, which in turn, applies the emergency braking control, and lights the warning lamp.

Title: Flameless atomic absorption spectroscopy - using sample carrier and heater, made of graphite tube with internal casing of pyro-carbon
Inventor: HUETSCH BRUNO
IPC: G01N21/74
Filed: 1980-08-12
Abstract: A sample darrier with a tubular case and a graphite heating device are suitable for flameless atom absorption spectroscopy. The carrier is a graphite tube (1) forming an impermeable carrier and exhibiting an essentially constant resistance making it usable as a heater. It is simple to make. The casing tube (6) consists of an impermeable carbon material of larger resistance than the graphite tube fitting inside the graphite tube and extending over the length of the sample carrier. It may be made of a pyrocarbon material and may have grooved walls. The variation of measurement sensitivity is small because of the casing tube impermeability, the constant resistance of the graphite tube, and the indirect heating of the casing tube. The carrier lasts about twice as long as pyrocarbon coated graphite tubes.

Title: Heating system with recovery of transmission heat
Inventor: SCHMITZ JOHANNES DIPL ING
IPC: F24D3/18
Filed: 1981-03-31
Abstract: For the effective reduction of the energy consumption in building heating, four measures must interact: improvement of the heat transmission between circuit medium and room air by enlargement of the heating surface, reduction of the energy losses by heat insulation and reduction of the temperature difference between the heat-exchanging media, heat recovery from the water vapour diffusing through the walls, utilisation of waste heat and environmental heat from building facade and the ground. All four measures are realised by the heating system with recovery of transmission heat in that different structural components of the building are reconstructed according to the requirements of the heating system. The reduction of the energy losses and the reduction of the temperature differences between the heat-exchanging media make possible a drastic reduction of the capacity of the heat generator. By heat recovery and utilisation of waste heat and environmental heat, the energy requirement, which must be covered by primary and secondary energy carriers, is reduced.

Title: Concave mirror lighting fixture, in particular headlight
IPC: F21V5/00
Filed: 1981-10-30
Abstract: The invention relates to a concave mirror light fixture having a concave mirror reflector with at least one luminous element which is arranged in the focal region of the concave mirror reflector, and further optical means which are preferably arranged in the cover plate of the concave mirror reflector. Concave mirror light fixtures are often used as headlights on vehicles. In order to increase the illuminance in the area between the point of incidence of the axial principal light bundle on the roadway and the vehicle, there is arranged between the cover plate and the luminous element a collector lens which collects the light emerging forwards from the luminous element. Optical means which deflect the collected light downwards are then arranged in front of this collector lens. Again, it is possible for the gap between the point of incidence of the axial principal light bundle and the vehicle to be better lit up by arranging in the region of the light bundle collected by the concave mirror reflector special optical means which deflect downwards and direct a part of the axial light bundle into said gap.
