Title: Modifying fly ash for use as additive for concrete - by melting and granulating part of it and mixing with remainder
Inventor: SCHOLZ HANS DR ING
IPC: C04B18/08
Filed: 1975-09-03
Abstract: Fly ash that cannot be used alone as an addition for concrete because of falling short of the requirements of the German standards (DIN 1045) can be modified to fulfil these requirements by the addn. of slag granulated in a melting chamber. The slag is added in such an amt. that the mixt. has (a) a calcination loss 5 wt.%, (b) glassy components >50 vol.%, (c) a specific surface area >=3000cm2/g. and (d) more than 50 wt.% of the particles equal to or smaller than 40 mu. By this method a fly ash that could not be utilised heretofore, can be modified by melting a part of it in a firing chamber installed nearby and mixing the resulting glassy granules with the unmodified part of the fly ash to use the mixt. as an addition for concrete. The slag has nearly the same chemical compsn. as the fly ash, its calcination loss however, is nil, and it is completely converted into the glassy state. The grain size can be reduced as required and the specific surface area can be increased by finely grinding the slag. The economy of the process is good.

Title: Frame synchronisation for PCM transmission system - uses sign change suppression at signal edge in middle of two phase bit signal
Inventor: HENTSCHEL RAINER DR ING
IPC: H04L25/49
Filed: 1975-10-18
Abstract: The synchronisation of very short PGM transmission frames wastes no transmission capacity on sync. bits. The PCM signals are transmitted in a self-clocked two-phase bit format. At the transmitter a frame clocking signal is used to suppress the signal sign change at the signal edges in the centre of each two-phase bit. This sign change is reversed at the beginning and end of a bit within a grame. At the receiver the absence of signal edges at the centre of a bit is used to sinchronise the frame clocking signal.

Title: Producing milk with standardised fat content - by subjecting flow line for fat-rich portion to back pressure
Inventor: SCHWEER GEB KIRCHHOFF INGEBORG
IPC: A01J11/10
Filed: 1976-06-23
Abstract: Cream with a standardised fat content is made from milk which is sepd. into a low-fat portion and a fat-rich portion a flow path for the fat-rich portion being subjected to a back pressure at a throttling back position. The back pressure is regulated in dependence on the difference between the density of the low fat portion and the fat-rich portion downstream from the throttling back position. This difference is used as an actual value signal for the fat content of the fat-rich portion, which together with a rated value and the corresponding deviations are fed into an integrator with a store. Signals corresponding to the changes in flow time of the low fat portion over a predetermined path at intervals in relation to the overall time are fed into the integrator and this controls the back pressure. Storing of separate fat rich portions is not required.
