Title: Voltage signal operation of magnetic core stores - whereby voltage generators are monitored ly auxiliary magnetic cores
Inventor: COLIN LEONARD DIPL-ING
IPC: G11C11/06
Filed: 1973-10-17
Abstract: The circuit arrangement provides a means of operating magnetic core stores by means of voltage signals which are monitored by auxiliary magnetic cores, so providing greater operating speed and improved stability of function. In the circuit, the current generators of the word-organised memory store are replaced by voltage generator whose transistors each have a diode between base and emitter. The inductive effect of these diodes is supplemented by an inductivity, which can be regulated, so that the output signal has a reduced critical time. The magnitude of the voltage impulses does not need to be constant and the number of selectors required is reduced by the use of highly permeable ferrite cores.

Title: Aircraft sound reduction and wing edge de-icer - has exhaust discharge pipe internally fixed to leading edge of wing
Inventor: PLETSCHACHER PETER
IPC: B64D33/04
Filed: 1974-03-20
Abstract: Exhaust gases from a piston also engine are diverted from the exhaust manifold through elbow and equalising bellows joints along a pipe set inside the shell of the leading wing edge. The exhaust gases are then discharged through openings at the wing tip. This system not only allows efficient ice formation on the wing edge, but acts as a noise reducing system and the gas discharge at the wing tip favourably influences the tip vortex. The system can be used for a single engined aircraft, in which case the exhaust flow is divided at a junction or for two or more engines where it is led away symmetrically in ducts.
