Title: Waste heat utilisation from power stations - has heat exchangers passing heat to ground water and thence to environment
Inventor: HEEKE FRANZ-JOSEF
IPC: F01K3/08
Filed: 1974-01-02
Abstract: It is proposed that large quantities of waste heat from atomic power stations and the process industries should be passed to groundwater systems via heat exchangers rather than allowing such waste heat to create mists and clouds by discharge through cooling towers etc. Heat entering groundwater systems would be subsequently radiated from the ground and would serve to improve the climate of the environment, to assist in agriculture and to warm parks and streets. Alternatively the groundwater could be flowed through pipes to ensure the heat was passed to the atmosphere without increasing its moisture content.

Title: Apparatus performing asynchronous correlation - is used for generation of ideal correlation function from binary coded pulse train
Inventor: SEIDLER PETER DR ING
IPC: G06F17/15
Filed: 1974-06-27
Abstract: The pulse train is split in two series x(t) and y(t), at the transmitter which are so selected, that their secondary peaks of summated autocorrelation functions cancel each other, and the sum of these series' lengths is equal to the length of the pulse train to be binarily coded. The two series are interlaced with each other, and a carrier is modulated with different phases, depending on polarity and the series; a correlation device at the receiving end eliminates the phase difference caused by transmission time, and then the correlation function is produced; the two series are so interlaced, that a bit of one series is followed by a bit of the other.

Title: Dialling pulses regeneration cct. - designed for use in telecommunications exchanges with comparator
Inventor: SCHMID REINHARD DIPL ING
IPC: H04Q1/36
Filed: 1974-08-12
Abstract: The comparator compares readings of two counters, of which one counts the incoming distorted pulses. The above comparator is in the form of an equivalence circuit, and the counters are pref. cyclic counters; the comparator output is connected through a delay line delaying the "unequal" signal, to the dialling pulse generator which delivers pulses at a constant repetition frequency and pulse width, so long as the "unequal" signal is at its input; the generator pulses are counted by the other counter; the capacity of the two counters is smaller than the greatest number of dialling pulses in a pulse train, but large enough to prevent, even for longest and quickest incoming pulse trains, the overrunning of the second counter by the first; this capacity is expressed by a specified equation.

Patent DE-2512786-A1 (DE)
IPC: F16D65/52
Filed: 1975-03-22
Abstract: During the braking process of the brake, a component (2) lifts upwards (B) an adjustment element (4) and an adjustment spindle (6) and a coupling component (7). A freewheel (9, 10) which is only connected in terms of rotation to the adjustment element (4) in the readjustment direction of the coupling component (7) is also moved with the adjustment element (4). The transverse element (9) of the freewheel (9, 10) bears a control component (12) which is guided in a vertical section of a link guide (26) during the movement of the freewheel (9, 10). If wear has occurred on the brake component, the adjustment element (4) is lifted further upwards and the control component (12) is turned by a bent section of the link guide (26) in the freewheeling direction. During the release process of the brake, with the control component (12) rotated, the control component (12) is moved downwards. During the running up on the link guide (26), the control component (12) adjusts the adjustment element (4) in the blocking direction by means of the freewheel (9, 10). In this way, the adjustment spindle (6) and the coupling component (7) are also moved in the readjustment direction. Each time braking occurs, the wear on the braking component is monitored and, if necessary, the braking stroke is readjusted. In the case of spring-loaded brakes, the monitoring of the wear takes place in the fully utilised area of the spring-loading so that there is never a reduced braking force acting on the brake component. <IMAGE>
