Title: Electrical transformer testing circuit with wide range - needs no matching transformer and provides voltage and phase angle error indication
Inventor: FREYGANG HANS-JOACHIM DIPL ING
IPC: G01R35/02
Filed: 1975-03-07
Abstract: The transformer testing circuit will operate with between one hundredth and twice the nominal transformer input voltage. An input voltage is simultaneously applied to the primary windings of the test transformer and a standard transformer. The outputs of both transformers are selected via potential dividers and connected to a test circuit. The rectified outputs are connected to a differential operational amplifier and the unrectified outputs connected to another differential amplifier. The first amplifier's output is the difference voltage output of the two transformers. This voltage together with an unrectified secondary voltage from the standard transformer form the input of multiplier whose output and that from the second amplifier are connected to a third amplifier.

Title: Mixer with coolant fed shaft for hot materials - such as coal pyrolysis and briquetting materials
Inventor: DREHER INGO DR ING
IPC: B01F15/06
Filed: 1975-05-27
Abstract: A mixer has >=1 mixer shaft through which a coolant flows, and which is particularly for operation at temps. in excess of 500 degrees C. The shaft incorporates a coolant pipe and an air gap is maintained between the outside of the coolant pipe and mixer shaft. Lower intensity cooling can be achieved to reduce heat losses from the material being mixed and to minimise thermal stresses in the coolant shaft. This lower intensity cooling is achieved using water cooling, which is cheaper simpler and safer than cooling with oil, steam etc. The mixer can be usefully applied in situations where a recycled fine-grained heat carrying solid is mixed with fresh cold material, e.g. in pyrolysis of coal and prodn. of hot briquetting materials.

Title: Electromagnetic safety ratchet stops for switchback railway - has electromagnet operated dependent on vehicle speed to avoid noise
Inventor: MORSBACH PAUL DIPL ING
IPC: A63G21/04
Filed: 1975-09-11
Abstract: On the ascending sections, the car (3) is secured against the risk of a broken traction cable by a pawl (8) which clicks over a ratchet (7). To save the noise, the invention uses an electro-magnet to hold the pawl away from the ratchet when this is safe. The energy for the electromagnet would come from a small generator driven from one of the car's running wheels and producing a voltage dependent on the speed of climb. When this speed falls too low, the electro-magnet fails to overcome the existing spring, and the pawl would be returned to click over the ratchet.
