Abstract: ABSTRACT OF THE DISCLOSURE     A cruise speed control apparatus for aircraft wherein small differences between the target Mach command and the actual Mach number of the aircraft are used to displace the aircraft from its reference altitude to either increase or decrease actual Mach number in the short term.  Long term differences are corrected through a special isolation filter to separate the engine control loop and pitch control loop dynamics and an integration technique to adjust the automatic throttles about a thrust target for the commanded Mach.  Large differences between the target Mach and the actual Mach or large charges in the commanded Mach are compensated for by a non-linear gain that effectively increases or decreases the target thrust to cause the aircraft to accelerate or decelerate to the commanded Mach.

Abstract: PROGRAMMABLE, MECHANICAL SYSTEM FOR FEEDING         CUT SHEET PAPER TO A PRINTER            Abstract of the Disclosure A mechanical system for feeding cut sheet paper to a printer from one of several cassettes.  A mechanical selector is mounted in each cassette so that it can drive a paper feed roll mounted in that cassette.  The cassettes include insert guides which allow each cassette to be replaceably mounted in at least one side rail secured on the printer.  The side rail has guides that receive and automatically locate each cassette on the printer with a simple "drop in" engagement.  The side rail supports a gear train or an equivalent power transmission arrangement that has a common drive and extends to all of the cassettes.  A power input gear of each selector engages an associated gear of the gear train.  The selectors each include a combination mechanism that allows the selector to transmit power only after the drive shaft has supplied a programmed pattern of rotations and counter-rotations to the selectors.  A unique association between the programmed pattern of rotations and the selection of a given cassette is established either by varying the "combinations" of the selectors or by using the same combination but varying the gear ratio between the drive shaft and the power input gear of the selector.

Abstract: ABSTRACT OF THE DISCLOSURE      The invention determines the existence of abnormal circuit conditions in lines of a group of interface lines without using redundant duplex lines.  The interface lines are subdivided into a first group, used when the present invention is being used to locate abnormal circuit con-ditions, and a second group, which is not used when the present invention is being used to locate abnormal circuit conditions.  Each first group line is connected to a corre-sponding input terminal of a first exclusive or gate and a second exclusive or gate at an input and output, respectively. The first and second or gates are input to a matching circuit, an output signal therefrom indicating an abnormal circuit condition in the first line group.  As a result, since the first group lines are used when the present invention is being used to locate abnormal circuit conditions, each first group line is tested individually for an abnormal circuit condition.  However, since lines of the second group are not used when the invention is locating abnormal circuit conditions, lines of the second group are tested, collectively for an abnormal circuit condition.  One line of the first group is connected to an input of the second group.  The output of the second group is connected to an additional input of the second exclusive or gate.  An output signal from the matching circuit indicates the existence of an abnormal circuit condition in at least one line of either one or both of the first and second group of lines.

Abstract: ABSTRACT OF THE DISCLOSURE  A method and a device for regulating the heating of a thermostatically controlled enclosure of a quartz oscillator.  During a first stage, the thermostatically controlled enclosure is exposed to an external temperature close to the maximum operating temperature and the frequency of the oscillator is measured.  During a second stage, the thermostatically controlled enclosure is exposed to an external temperature close to the minimum temperature of the range and the difference between the frequency of the oscillator and the frequency previously measured is cancelled out by modifying the distribution of the powers dissipated by the heating elements of the thermo-statically controlled enclosure.  The heating of the enclosure is performed by a chain of voltage stabiliser semiconductor circuits connected in series, each of the circuits being traversed by a regulated heating current. The regulating of the heating action is performed by modifying the stabilised voltages of the circuits.
