Filed: 1972-12-19
Abstract: 1343560 Automatic phase control; radio receivers SIEMENS AG 19 Dec 1972 [28 Dec 1971] 58462/72 Headings H3A and H3Q In a circuit for reducing phase modulation present on a signal, the signal is fed via a limiter 1 to a differentiator 2 to produce a triggering input to a monostable circuit 3 whose time constant is controlled by a correction signal such that its output is substantially free   from phase modulation. The output pulses from the monostable 3 have a fixed trailing edge and a variable leading edge and may be converted to constant width pulses by a further differentiator 4, and monostable 5. The output signal is fed to a phase detector 6 to produce the correction signal which adjusts the time constant of monostable 3. Differentiator 4 and monostable 5 may be omitted if constant width pulses are not required, Fig. 7 (not shown). As described the input signal is a SSB signal plus its carrier, and the output is the unmodulated carrier necessary for demodulation.

Patent GB-2056748-A (GB)
Title: A method for eliminating local gas concentrations in stratified atmospheres
IPC: G21C13/10
Filed: 1979-08-20
Abstract: Local gas concentrations in stratified atmospheres, in particular in stratified atmospheres present in closed systems, are eliminated by producing a disruption in the stratified atmosphere which impairs the equilibrium of the stratified atmosphere at least locally, so that a gas volume experiences an upwardly or downwardly directed acceleration, thereby causing a convection current. The disruption is caused by producing a local change in density in the respective atmospheric strata by introducing a gas having a suitable density or by supplying or dissipating heat.
Patent GB-2036506-A (GB)
Title: Integrated switching and transmission network
IPC: H04Q11/04
Filed: 1978-08-16
Abstract: An integrated switching and transmission network comprises a digital switching system for transferring communication information without congestion. The switching system consists of one-way switch modules (SM) which are connected through two-way time division multiplex transmission links (La-Lb) to link modules (LM) each including a control unit (CU) for establishing communication paths within an associated line group (LG) as well as for controlling the switching system in cooperation with the control units of other line groups. Each of the switch modules (SM x/y) is allotted to two of the two-way links and comprises a time stage (TS) and a signalling logic circuit (SL). The input of each module is connected exclusively to one way (La, x) of one (La, x-Lb, x) of the two-way links, whereas the output of each module is connected exclusively to the other way (Lb, y) of the other two-way link (LayLby). For the reliable control of the network, transmitting control units generate signals. Each signal addresses one of the signalling logic circuits, which converts the signal to an operation signal by which the associated time stage is operated or to a signal intended for the receiving control unit. Furthermore, control messages are used and transferred between the control units through the time stages. The time stages carry out the required time interchanges for the transfer of said control messages and communication information between the line groups.
