Title: Shunt motor bidirectional variable speed control - controls armature current using network incorporating many protective features
Inventor: LAUFFER HANS PROF DR ING
IPC: H02P7/293
Filed: 1974-10-07
Abstract: The motor may be used on textile machinery. The motor control is achieved by altering the amplitude and direction of the armature (A2) current, the field (A3) current being held constant. No very sudden changes in demanded speed are allowed, and current limitation to the armature, depending on the direction in which it is presently moving, is imposed. This is achieved by a large logic network incorporating several feedback arrangements. The first involved the demanded or set point armature current. A set point voltage is processed to avoid sudden change, using an integrator and compared with a sawtooth generator to produce impulses of mains frequency and of duration proportional to the demand voltage. This signal, which is established by a feedback loop (A21, A34) is applied to the armature drive amplifiers.

Title: Isotherm imager producing thermal picture of stationary objects - includes optomechanical scanner with IR camera and beam compensation to avoid flicker
Inventor: ZSCHAU HORST DIPL ING
IPC: H04N5/33
Filed: 1975-03-01
Abstract: The isotherm imager, for producing a thermal picture of stationary objects, has an optomechanical system (2, 5, 6) between the objective lens (1) and the target of the IR camera tube (4). The optomechanical system periodically moves the incident radiation over the target so that as far as the camera is concerned the temperature of the object is constantly changing and it produces an output video signal whose amplitude is proportional to the rate of change of the temperature thereby enabling an object of constant temperature to be viewed without the relatively fast decay of the video signal that would occur without this scanning motion. The electron beam is moved to compensate for this motion so that picture flicker is eliminated.

Title: Mass flow in gas:pipeline - is derived from upstream:downstream sound transmission phase difference found using delay lines
Inventor: REIBER HANS ING GRAD
IPC: G01F1/86
Filed: 1975-09-24
Abstract: The analogue value of a phase difference del phi between sound propagation in and against the flow direction is measured. The pressure in the pipeline is measured independently, and the above phase difference is multiplied by the pressure, and by an instrument constant K obtained by calibration. The product is a measure for V/T (flow velocity/absolute temperature). A delay line is connected in each direction in parallel with the test section. The phase of the frequency received through the test section is compared with that of the signal transmitted through a delay line which is readjusted accordingly. The phase difference delta phi is derived from the differences of the delay times.
