Patent DE-2632910-A1 (DE)
Title: Concentrating radioactive effluent by multistage evaporation - with liq. inlet at late stage and condensate recycling to earlier stages
Inventor: BRAND REINHOLD DIPL ING
IPC: B01D1/26
Filed: 1976-07-21
Abstract: A method of concentrating by evapn. radioactive or similar liqs. utilises multistage evapn plants. The liq. is introduced into a stage other than the first stage of the plant, pref. into one of the last stages or the last stage here it is evaporated and the vapour flows back as condensate into an earlier stage of the process, where it is again evaporated and distilled to increase the purity of the discharged vapour. Pref. the vapour in the last stage is condensed, the condensate is then degassed and then it is conducted back to the earlier stage. If desired condensate from the earlier stage may be conducted forwards to the last stage where it is evaporated again. Used to obtain a sufficiently high degree of purity to satisfy the latest requirements of 10-8 Curie/m3 as compared with earlier values of 10-6 for residual activities. The method enables this high degree of purity in radioactive liq. effluent to be attained in an economical process requiring min. maintenance.

Title: Offset printing machine colour roller cooling system - has concentric tubes forming meander path for cooling fluid counterflow system
Inventor: CAPPEL BERT ING GRAD
IPC: B41F31/00
Filed: 1976-12-23
Abstract: The colour roller for an offset printing machine incorporates a cooling and tempering system in which the cooling fluid flows through the interior, in a counter flow heat exchanger arrangement. Through the end of the spindle (2) is a tube (3) through which enters the cooling liquid. It passes around the end (4) of the roller, which acts as a displacement member. This guides it through a gap (8) between a separating tube (5) and then through holes (9) so that its flow is reversed, to travel through another gap (9) in the opposite direction. An outer tube (6) encloses this gap. The flow then is discharged through the space between the inner tube (3) and the hollow spindle (2), still in the opposite direction.

Title: Speed control circuit for brushless DC motor - has tachogenerator setting and resetting flip=flop that drives current-regulating transistor
Inventor: REICH JOACHIM
IPC: H02P7/288
Filed: 1977-03-30
Abstract: The speed control circuit, is used for regulation of a brushless DC motor. The circuit uses a tachogenerator to control a transistor that alters the current through the drive windings. The periodic signals from the tachogenerator are converted into rectangular-wave signals for applying to the reset input of an RS flip flop that controls the transistor. The rectangular-wave signals are also used as a triggering signal for a timing circuit which produces the flip flop set signal. The set signal is suppressed when the wanted speed is reached.

This is when there is a simultaneous orientation of the blade or blade gp. edges at 50-90 degrees, pref. 70-80 degrees, radially from the first blade carrier, and with the blades being arranged in gps. on >=1 carrier. There is a 0.1-2.5 mm gap between the blades of a gp., or each blade gp. forms a block with surface openings and with gaps between the gps. The design reduces operational energy costs in processing fibre suspensions to make them suitable for paper making.
