Title: Process for solution crystallisation on an industrial scale
Inventor: OELS UDO DR
IPC: B01D9/00
Filed: 1981-01-24
Abstract: The present invention is based on the finding that the volume-related stirring power is a generally usable criterion for transferring crystallisations from solutions from the laboratory scale to the industrial scale and therefore relates to a process for crystallisation from solutions on an industrial scale using a crystallisation vessel furnished with a stirrer, suitable physical and technical boundary conditions being determined on a laboratory scale, which process is characterised in that the suitable volume-related stirring power is determined on a laboratory scale and this is applied to the industrial scale virtually unchanged together with other physical and technical boundary conditions determined on the laboratory scale. In this manner, solution crystallisations can be transferred directly from the laboratory to the industrial scale, the particle size of the crystals changing by at most +/- 20 %, frequently by significantly less.

Title: Method and circuit arrangement for multiplication of PCM words coded in non-linear fashion according to a 13-segment characteristic complying with the A-law
Inventor: DRESCHER MANFRED DIPL ING
IPC: G06F7/49
Filed: 1981-03-25
Abstract: Multiplication of non-linear-coded PCM words may be required, for example, in the operation of digital filters. The current method of linearising the PCM words before the calculation operation incurs substantial component cost and long transit times. A multiplication of this kind is therefore carried out according to the invention in such a way that, while avoiding preceding linearisation, the PCM word components which indicate the numbers (e1, e2) of the characteristic segments and the gradation (m1, m2) of these segments are subjected to arithmetical operations which correspond to the product of the definition parameters which, using the aforementioned word components, express the linear values of the PCM words.
Patent DE-3112003-A1 (DE)

IPC: G01N29/02
Filed: 1981-03-26
Abstract: An ultrasonic measuring sensor for the fixing station of a non-mechanical printing or copying device has an electroacoustical transducer for both transmitting and receiving ultrasonic oscillation, and a reflector spaced a distance from the transducer for reflecting the oscillation transmitted by the transducer back to the transducer. The measuring path between the transducer and the reflector is surrounded by a fine mesh net having a mesh size which is significantly smaller than the wavelength of the ultrasonic oscillation. The mesh of the net is selected so as to permit the vapor concentration inside of the net to follow the changes in the average concentration at the fixing station with sufficient rapidity while shielding the measuring path against brief and topically limited concentration fluctuations.

IPC: G05D16/06
Filed: 1981-04-04
Abstract: A pressure governor for the air brake system of motor vehicles has a housing (1) having a blow-off aperture (26). In the feed duct (2) a non-return valve (5) is provided, downstream of which a connecting duct (6) branches off to a control chamber (7) of a control piston (8). The control piston (8) is supported in a spring chamber (10), vented to the atmosphere, on an adjustable spring (11) to shut off at the set value. The pressure governor has a switching piston (23) with switch chamber (22) for the actuation of an outlet valve (27, 28) lying in front of the non-return valve (5) and leading into the atmosphere. Between the control chamber (7) and the switch chamber (22) an inlet valve (15, 18) is formed and following the switch chamber (22) an outlet valve (15, 19) for the venting of the switch chamber (22) into the atmosphere is formed. In addition to the blow-off aperture (26), known pressure governors have a separate aperture leading to the atmosphere for the venting of the spring chamber (10). There is a risk of water and dirt particles getting into the spring chamber of the pressure governor through this aperture. For reducing this risk, complicated and expensive devices, especially non-preloaded non-return valves or the like, are known. The blow-off aperture (26) of the new pressure governor is at the same time the only venting aperture of the pressure governor, which pressure governor has a continuous venting duct (17, 30), which passes through the control piston (8), the switching piston (23) and the outlet valve (27, 28) and to which on the one hand the spring chamber (10) and on the other the switch chamber (22) are connected by way of the outlet valve (15, 19) in the opened state. <IMAGE>
