Title: Pulse train generator
IPC: H03K5/156
Filed: 1974-10-25
Abstract: A circuit is disclosed for generating a periodic pulse train having any fixed desired duty cycle from a periodic input signal which may be either analog or digital. The input signal is fed to a transistor amplifier whose bias can be varied. The output of the transistor amplifier is coupled to an amplifying element whose possible voltage swing is limited to provide the desired pulse train. The desired pulse train from the amplifying element is coupled through a low-pass filter prior to comparison with a reference voltage in a differential amplifier. The voltage difference at the output of the differential amplifier adjusts the bias of the transistor amplifier such that the voltage of the low pass filtered desired pulse train is very close to the reference voltage.

Title: Method for increasing the mechanical features and the resistance against corrosion under tension of heat-treated aluminum alloys
IPC: C22F1/04
Filed: 1975-01-03
Abstract: The invention relates to a method of heat treatment which is applied to forged aluminum alloys, whereby the mechanical characteristics and resistance against corrosion under tension are increased considerably. This method is characterized by heating prior to tempering, above the temperature of eutectic melting, while remaining below the temperature of the start of the melting at equilibrium. The liquid phase formed temporarily is resorbed progressively, while the formation of pores is avoided by a sufficiently low hydrogen content of the metal. The application of this procedure to several aluminum alloys made it possible to observe increases of the limit of elasticity and of the break load of the order of 7% and a non-rupture stress under tension in 30 days at least equal to 30 hb.

Title: Reproducing apparatus with drop out suppression circuit for audio and video signals
IPC: G11B20/06
Filed: 1975-09-11
Abstract: An apparatus for reading a record carrier on which a combined video signal is recorded in a single track, in particular a disc-shaped record carrier on which the signal is recorded in optically coded form.

Said clamping circuit normally transfers the applied modulated video signal unmodified. During a dropout the modulated video signal consisting of the modulated sound and pilot signal is clamped at its average value by means of said clamping circuit, so that a substantial improvement is obtained in respect of the sound signal. Thus, the length of time of sound signal clamping is minimized and the sound quality is improved.
