Abstract: ABSTRACT OF THE DISCLOSURE         An FM signal is applied to an input of a differential amplifier including a pair of transistors having symmetrical characteristics.  A 180° phase shifting circuit is connected between two inputs of the differential amplifier.  Accordingly, the inputs of the pair of transistors of the differential amplifier receive the FM signal, as converted into an AM signal.          The respective base-emitter rectifying junctions of the pair of transistors each rectify the AM signals, as received.  The emitter electrodes of the pair of transistors are commonly connected through a predetermined resistor, with the common connection point being connected to ground through a capacitor.          Accordingly, a smoothing circuit is implemented by the emitter resistor and the capacitor.  A load resistor is connected to the collector electrode of one of the pair of transistors, so that a detected output is withdrawn therefrom.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for adhesively bonding together in edge abutting relationship two sheets of woven felted or other textile such as carpet using a joining tap which includes electrically conductive-metal foil or wires and an integral layer of heat softenable adhesive.          Electric current is passed through the foil or wires to thereby heat and soften the adhesive.  A control circuit senses the voltage and current in the foil or wires and controls the current in accordance with an adjustable pre-determined value to heat the adhesive to a temperature at which the adhesive becomes tacky.  The control circuit maintains the adhesive in the tacky state while the abutting edges which overlap the tape are adjusted as required to form the desired join.  The control circuit is then adjusted to increase the current in the foil or wires to increase the temperature thereof and melt the adhesive so that it flows into the material of the sheets.  The current is terminated when the adhesive is fully melted so that the adhesive sets to bond the edge portions of the sheets to the tape.

Abstract: ABSTRACT        In a system for controlling electric power supplied to corona-generating electrodes in an electrostatic precipitator (10), an opacity-sensitive transducer (20) produces an output signal proportional to the opacity of the flue gas exiting from the precipitator (10). The signal from the transducer (20) is compared in comparators (304 and 305) with pre-set upper and lower limits defining a permissible opacity range for the flue gas.  When the signal from the transducer(20) exceeds the pre-set upper limit or falls below the pre-set lower limit, automatic voltage controllers (40) are activated to control the power supplied to the corona-generating electrodes in order to restore the flue gas opacity to the permissible opacity range.

Abstract: ABSTRACT OF THE DISCLOSURE        A safety device for a power chain saw or the like   The safety device has a mass body which is responsive to acceleration forces and is operatively connected with a brake device.  The mass body has at least one support part under a holding force, the mass body being displaceable from a rest position under the effect of the acceleration force (a "monostable inertia switch").  The mass body in a preferred embodiment is made as a bar or rod magnetically attracted to a supporting surface and capable of being tilted from an upright or vertical position temporarily into electrically con-ducting engagement with an annular ring spaced therefrom and sur-rounding the upper free end of the bar or rod, permitting electrical connection to be established to actuate a brake device for stopping the power chain saw in case of an emergency, including tripping, falling, slipping, or sudden shock, as a safety feature for an operator of the power chain saw.  Alternatively, uniformly spaced spring means can be provided radially aligned relative to a ball or spherical member also serving as an inertia body for triggering a brake release or actuation signal responsive to acceleration force in all directions rather than only in one plane of movement.  A permanent magnet or electromagnet can be used for purposes of actu-ation of the brake device responsive to accelerating force in any direction.  Also, a luminous diode may be arranged in a cover for a recess in which the mass body in the form of a ball or rod is lo-cated subject to displacement movement, and this luminous diode is directed in an angle of incidence against a reflector surface of the mass body,  a photo-diode, photo-transistor or the like is arranged in an angle of reflection relative to the reflector surface.          Alternatively, on the cover there is arranged a magnet switch or dry-reed switch, or an inductive or capacitive proximity switch, above the mass body.  Control lines are connected and provided with a holding part and an abutment part which are both electrically conductive;  an insulation is arranged between the holding part and the abutment part as well as on the outer surface thereof.  A cover is arranged above the mass body in the side remote from the counter engagement surface of the holding part;  this cover is spaced above the mass body by a distance which is less than the depth of the recess.  The mass body may be a permanent magnet, and has an engagement surface which engages against a counter en-gagement surface of the holding part by way of magnetic force.

Abstract: TITLE          NON-CONTACT OPTICAL APPARATUS FOR MEASURING THE          LENGTH OR SPEED OF A RELATIVELY MOVING SURFACE          INVENTORS                   Jacques Domey Marc Rioux ABSTRACT OF THE DISCLOSURE           The apparatus generates two optical beams which are directed to a relatively moving solid surface where an interference pattern, having substantially parallel fringes, is formed.  The light is scattered and thereby modulated by irregularities on the surface.  This modulated light is received and the signal is processed to indicate the length of the surface or its relative speed.  The signal processor converts the modulated light signal to a pulse train, and adds pulses to the pulse train when a drop-out in the signal is detected, i.e. when the time between pulses in the pulse train is greater than a factor times the average period of the pulse train.  The corrected pulse train is a function  of the length of the surface or the relative motion between the apparatus and the surface.

Abstract: RCA 75,526 ABSTRACT OF THE DISCLOSURE          A primary winding of a power transformer is coupled to a source of DC voltage.  First and second controllable switches are coupled to the primary winding in a push-pull arrangement.  A control circuit responsive to a deflection rate input signal that is synchronized with deflection circuit scanning applies a turn-off switching signal alternately to the two controllable switches during each deflection cycle.  In response to the turnoff of each one of the two controllable switches, a turn-on switching signal is applied to the other switch to develop a deflection rate alternating polarity output voltage across an output winding of the power transformer.  The output voltage is rectified and applied to a deflection generator to thereby energize the generator into developing scanning current in a deflection winding.

Abstract: The diffuser is symmetrical about an axis AA' and has a flared outer wall (2,3) going from an axial inlet to an outlet. The outer wall is divided into an upstream portion (2) and a downstream portion (3) by a circular bleed slot (1) disposed symmetrically about the axis. The profile of the outer wall is such that, in operation, the direction of fluid flow along the outer wall is from the inlet towards the outlet, both over the upstream portion, and over the downstream portion. Further, it is so arranged that the pressure gradient measured at the surface of the wall and along the direction of fluid flow is negative upstream from the bleed slot and positive downstream therefrom. This ensures that only a small percentage of the fluid flow needs to be bled off to achieve desirable flow conditions, thereby providing good diffuser efficiency.
