Title: Cooling particulate free flowing materials - by gravity flow over cooling surfaces with pulsed flow
Inventor: BRUENEMANN HILMAR DIPL ING
IPC: B01J8/08
Filed: 1975-10-29
Abstract: Process for cooling free flowing solids contg. sublimable or volatile components involves passing them over a cooled surface. The flow is approx. free fall from top to bottom of the cooler. However, this is carried out as a series of pulses. The mass flow per pulse should be 1.3 to 15 times the average mass flow, preferably 2 to 6 times. The increased impulse of the particles compared to the mean flow, induced by the pulsed flow, is augmented by reaction on the cooling surfaces. These consist of bundles of cooling plates joined together in parallel inclined at an angle of 30 degrees to 70 degrees to the horizontal. The bundles are so arranged under each other that the angle of succeeding rows in the opposite of the one above it. Method prevents occurrence of accretions.

Title: Correlation functions determination for two pulse trains - uses two counters and one counts up and down, depending on coincidence of bits in pulse trains
Inventor: STRAEHLE FRITZ DIPL PHYS DR
IPC: G01R29/02
Filed: 1976-04-30
Abstract: Pulse trains are reproducible and of any length. Each pulse train is generated by a pulse generator controlled by clock pulses and delivering a pseudo-random pulse train. Their output signals are bit-by-bit compared for coincidence or non-coincidence by a logic comparator. Clock pulse train (T) controlling the pulse generators (G1, G2) is in addition applied to two counters (Z1, Z2). When the first counter (Z1) reaches a specified state, it delivers an output signal which controls the second counter (Z2) so that it counts up or down, depending on coincidence or non-coincidence of bits in the comparator (V). This output signal also stops supply of clock pulses to one of the generators during one cycle. It also causes delivery of the number reached by the second counter, and resetting of the latter to its initial state.
