Abstract: A LINEAR MOTION IMPACTOR DEVICE     Abstract of the Disclosure A linear motion impactor device includes an impactor which provides force to a hammer shank only upon application of the hammer against a surface to be impacted thereby saving power and reducing noise during periods of non-use.  The impactor which operates on the hammer shank is mounted in a housing and is formed with a bore normally coincident with the axis of rotation of an eccentric cam which is rotated by a power source.  The impactor is retained in this center-line position by a compression pad positioned between the impactor and the housing and further positioned diametrically opposite the hammer shank.  In the two embodiments described, either linear bearings or shear pads ensure linear motion to the impactor during operation.

Abstract: DIAPHRAGM FOR PRESSURE SENSORS     ABSTRACT     A diaphragm consisting of multiple arches con-figured such that radial compliance is increased and pres-sure responsive radial compression loading will approximate radial tension loading resulting from deflection of an associated pressure sensor mechanism.  On the pressure receiving side of the diaphragm, a broad shallow convex section extends between two concave sections of tighter curvature.  The portions of the concave sections remote from the convex section each extend to a substantially cylindrical configuration.  A sharp convex bend extending to a flat radial flange provides an attachment edge with minimum attachment stress. A method of forming such a diaphragm to insure uniform wall thickness by allowing maximum lateral migration of the diaphragm sheet is also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE      .           Cereal grain dryer comprising an elongated vertical casing defining an open ended enclosure.  A combustion chamber provides hot combustion gases divided into two streams:  one flowing into a coil lining an upper section of the casing and the other flowing through a radiator   which heats up air before the latter moves horizontally across the enclosure by passing through two orifices of the casing.  The casing is likewise horizontally traversed by a cold air stream passing through two further casing orifices, below the hot air stream.          The cereal grains fall vertically through the enclosure and are moved by gravity.  They are dried with a good thermal efficiency without coming in contact with the combustion gases.

Abstract: ABSTRACT OF THE DISCLOSURE           A multi-channel recording and/or reproducing apparatus is disclosed, wherein a plurality of rotary magnetic heads scan a magnetic tape to form a plurality of skewed parallel tracks simultaneously.  These heads are aligned substantially in the scanning direction on a single head base plate.  Pre-ferably, these heads are so secured as to form parallel skewed tracks without guardbands therebetween.  Each head has the same thickness, and is mounted on a head base.  Even though the thickness of each head chip is the same, effective head gaps are formed to have different heights individually from the surface of the head base plate.  When forming guardband-less plural tracks, an azimuth recording technique is intro-duced in order to avoid crosstalk between adjacent channels during reproduction.

Abstract: ABSTRACT OF THE DISCLOSURE      A hydraulic pressure relief circuit including a main valve, a bleed flow orifice to provide stability to the main valve, a pilot valve having a differential area piston and a damping orifice in conjunction with an accumulator chamber.  System pressure is limited by opening the main valve and allowing fluid flow from the system back to tank.  The main valve is controlled as a bleed flow servo wherein the pilot valve meters the bleed flow from the bleed flow orifice to tank thereby controlling the opening of the main valve. Fluid flow through the damping orifice in conjunction with the accumulator chamber acts on the pilot valve to provide damping forces acting on the pilot valve with both rising and falling system pressures thereby limiting the maximum rate of pressure increase in the circuit.

Abstract: ABSTRACT OF THE DISCLOSURE The invention relates to a new method for simultaneous recovering vanadium, molybdenum and gallium from alumina factory aluminate liquor compris-ing an aqueous sodium aluminate solution.  The recovering is carried out in one step by electrolyzing the aqueous sodium aluminate solution at a temperature exceeding 70°C with a direct current having a current density of from 400 to 1200 A/m2 using a low-melting liquid alloy as a cathode and agitating said alloy mechanically.  The gallium is alloyed into the cathode in the course of the electrolysis.  By using the new process vanadium, molybdenum and gallium can be recovered simultaneously in one step with good efficiencies without any preliminary treating of the aluminate liquor and without using any anxiliary chemicals.

Abstract: ABSTRACT OF THE DISCLOSURE           A motion transmitting remote control assembly of the type for transmitting forces along a curved path by a flexible motion transmitting core element movably supported in a flexible conduit.  The assembly includes a support member adapted to be connected to a support structure (such as a bulkhead) and the conduit includes a slider member slidably disposed in a passageway extending longitudinally through the support member.  The support member includes a transverse guideway in which is disposed a metal L-shaped latch member having an aperture in one leg through which the slider member extends.  A coil spring reacts between the support member and the other leg of the latch member for biasing the bottom of the aperture into engagement with the slider member.  The bottom of the aperture in the latch member has a tooth which coacts with ratcheting teeth on the slider member.  The coil spring urges the tooth of the latch member into engagement with the ratcheting teeth of the slider member and allows the latch member to be moved out of engagement with the slider member in response to a predetermined force.  A temperature-responsive slug is disposed within the coil spring in parallel with the coil spring for allowing movement of the latch member in response to the predetermined force above a predetermined temperature but requires a higher force for moving the latch member at temperatures lower than the predetermined temperature.
