The cores are constructed so that the permeability of one core changes with temperature at a rate which is different from the rate that the permeability of the other core changes, with respect to temperature.  A plot of inductance vs. temperature, thus varies so that the curves for the two cores intersect at the temperature which is to be sensed.  The cores are connected together in a four-arm inductance bridge network and a null detector is coupled to the bridge network to provide an electrical output signal.

Abstract: ABSTRACT OF THE DISCLOSURE          In a system that compares the rate of descent of an aircraft with its altitude above ground and generates a warning signal when the sink rate exceeds a predetermined limit for a particular altitude, the maximum warning time is limited to a specified value in order to minimize nuisance warning at higher altitudes.  At a descent rate above a certain value, the excessive sink rate warning signal is inhibited for combinations of descent rates and aircraft altitudes which would provide a warning greater than a selected time to impact, such as 30 seconds.

Abstract: PROCESS FOR THE CONTROLLED   COOLING OF FERROUS METAL     ABSTRACT OF THE DISCLOSURE     Austenitized ferrous metal. such as carbon steel, is quenched by means of an aqueous solution or a salt of poly-acrylic acid which develops an extremely stable and uniform water vapor envelope surrounding the steel.  Rate of cooling is controlled by (1) the molecular weight of the salt, (2) con-centration of the salt in the solution, (3) solution temperature, and (4) the degree of agitation of the quenchant solution. In the case of carbon steel, by proper selection of the above variables, the austenitic structure of the hot steel may be directly transformed into non-martensitic structures of improved ductility, machinability and cold working properties, such as fine striped pearlite, without the necessity of further heat treatments, such as tempering, following quenching.       The quenching solution may also be used to quench parts formed of alloy steel to obtain a martensitic structure without unwanted cracking and distortion. Non-ferrous metals may also be quenched using the polyacrylate quenching solution.

Abstract: A CHARGE-COUPLED-DEVICE QUANTIZING CIRCUIT                 ABSTRACT OF THE DISCLOSURE         A device for quantizing analog signals employing charge-coupled-device technology including a p-type substrate such as silicon having a dielectric insulating layer thereon which may be silicon dioxide.  A plurality of gates or electrodes are embedded in the insulating layer and are arranged in linear relationship to alternately form potential wells in the substrate and to function as transfer gates between the wells.          An analog signal represented by a quantity of charge carriers is injected into substrate and is transferred through the substrate to sequentially fill the potential wells until the original quantity of charge carriers is exhausted.  The potential wells can be equal in size so that each filled well contains equal amounts of charge carriers.  When the original quantity of charge carriers is exhausted the charge carriers in each of the filled wells are discretely shifted out of the quantizer to a threshold detector and the separate charge carrier packets from each potential well are counted to provide a measure of the amplitude of the original analog signal in digital form. The circuit has the flexibility that the depth of the potential wells, and therefore the quantizing step size can be controlled by the relative bias potentials applied to the gates.

Abstract: m ABSTRACT OF THE DISCLOSURE      A sliding piston for a hydraulic control device provided with piston sections, the piston sections being separated from each other by annular grooves.  Known similar apparatus do not permit for optimum reduction of reaction forces acting on piston movement over an entire fine control range.  This is particularly disadvantageous in the case of sliding pistons having large di-mensions and large oil circulation therethrough.  The present invention provides an improved hydraulic sliding piston that can be actuated over the entire control displacement with minimum force even with large amounts of high pressure liquid flow around the piston.  Accordingly, the sliding piston according to the present invention has diametrically opposed fine control grooves situated on the front side of the piston sections.  The annular grooves and the line control grooves are connected to each other.  Lateral faces of each fine control groove are open at a semi-circle to a cylindrical surface of the sliding piston and at right angles to a front surface of the annular groove separating the piston sections.  A front side of each fine control groove is provided with a milled concave slot.  A hydrodynamic body is exposed to the front side of the fine control groove and is provided with a sloped surface forming a throttling location.  The hydrodynamic body is eccentrically positioned in the fine control groove and is held therein in such a position that a radial surface of the hydro-dynamic body and the cylindrical surface of the piston sections are on the same diameter.

Abstract: ABSTRACT OF THE DISCLOSURE    The frame to which a backpack is fastened is formed of tubing bent in hourglass shape in rear elevation and two inward offsets in side elevation.  A horizontal rigidifying cross bar extends through about the middle of the top part of the hourglass and is adjustable at different elevations.  The upper end of a connector is fixed to the narrow part of the frame at adjustable elevations.  The lower end of the connector is fixed to a hip level belt stretcher.  The connector is constructed with gener-ally vertical ribs which are wide in a front-rear sense and thin in side-to-side sense so that the connector flexes about the Y and Z axes passing through the narrowest part of the connector, which is positioned close to the point of the spine of the wearer, where there is little or no bending of the spine during bending or twisting of the torso, but is rigid against flexing about the X axis.  A hip belt encircling the hips of the wearer is con nected to the belt stretcher at the lower end of the connector.          The tops of shoulder straps are adjustably connected to the cross bar and the lower ends to the lower part of the frame.  The pack weight is distributed between shoulders and hips.  Natural move-ments of shoulders and hips are not inhibited.
