Abstract: A laser beam levelling instrument has a pipe length which is vertically and centrally mounted in the cover of a casing. The ends of this pipe length are pivotable, so that it can always be held in the vertical position.

If the pipe length diverges from the vertical, then the current from batteries ensures that it is brought back into the vertical position by means of the eccentric shafts. A laser light source is located in the lower part of the pipe length and a further pipe length is inserted in the upper end of the pipe length and can be rotated by a third electric motor.

Abstract: Disclosed is an azimuth determination apparatus attached to a motor vehicle for determinating the forward direction of the vehicle. The azimuth determination apparatus includes an azimuth sensor for generating orthogonal first and second signals indicative of the forward direction of the vehicle. Two azimuth vectors are obtained on the basis of the orthogonal first and second component signals, first components of the two azimuth vectors being maximum and minimum.

Abstract: An air cycle thermodynamic conversion system compresses a compressible gas in a multi-stage compression process with intercoolers between each adjacent pair of compressors. The intercoolers return the compressed gas temperature to about ambient temperature before each succeeding compression operation. The compressed gas is heated in a heat exchanger passing a heated exhaust gas in counterflow with the compressed gas to increase the thermal energy of thereof. A minimum temperature gradient is maintained between the heating compressed gas and the cooling exhaust gas by establishing the two flows such that they both have about equal heat capacities. The heated compressed gas is expanded in a turbine to produce at least enough torque to drive the multi-stage compression system. Additional torque may be produced in the turbine for driving a using process. Alternatively, an excess of heated gas, beyond that required for driving the turbine, may be fed directly to a using process.
