Title: Temperature-stabilized low-loss ferrite films

Abstract: TEMPERATURE-STABILIZED LOW-LOSS FERRITE FILMS          Abstract of the Disclosure In the preferred embodiment, a monocrystalline film of substituted yttrium iron garnet (YIG) deposited on a <111> oriented gadolinium gallium garnet (GGG) substrate is formulated so that the temperature variation of the ferromagnetic resonance frequency of the film has an ordinary minimum.  For a range of temperature variations about the temperature at which the minimum occurs, therefore, the resonance frequency of the film is relatively insensitive to variations in temperature.  This minimum is believed to occur where the temperature variations of the demagnetizing effect and the temperature variations of anisotropy effects more or less counterbalance each other.  The counterbalancing effects are brought within range of each other primarily by the substitution of gallium or aluminum for iron and the substitution of lanthanum for yttrium in the substituted YIG.  Gallium or aluminum reduces the temperature drift of the saturation magnetization.  Lanthanum adjusts the misfit stress and thus the anisotropy effects.

Abstract: ?407   INVENTORS:   WALTER REIST and WERNER HONEGGER            INVENTION:   APPARATUS FOR OUTFEEDING FLAT PRODUCTS, ESPECIALLY PRINTED PRODUCTS, ARRIVING IN AN IMBRICATED ARRAY     ABSTRACT OF THE DISCLOSURE          An apparatus for outfeeding printed products arriving in an imbricated product stream, in which, in each case, the leading edge of a printed product overlies the rearward edge of the pre-ceding printed product.  The arriving imbricated product stream is infed, by means of a conveyor belt or band, to the conveying gap of a deflection or turning device where the imbricated product stream is turned through about 180°.  This deflection device com-prises a deflection drum about which there is guided an endless conveyor belt.  A pressing or contact belt, held under tension, is arranged opposite the deflection drum and forms together therewith the conveying gap.  The pressing belt presses the printed products, traveling through the conveying gap, against the deflection drum.         The conveyor belt guided about the deflection drum conveys the printed products, departing out of the conveying gap, towards an individual conveyor.  This individual conveyor possesses in-dividually actuable grippers which, viewed in the product convey-ing direction, are arranged behind one another and attached to a traction element.  These grippers engage the printed products, in-fed by the conveyor belt, at their leading edges and convey such upwardly away.  At the transfer region the conveying direction of the individual conveyor extends from below towards the top and transversely with respect to the surface of the printed products, so that the latter are raised upwardly and detached from the im-bricated product stream.

Abstract: TRACTOR TRANSMISSION SHIFT CONTROL               Abstract of the Disclosure A shift control for a hydromechanical transmission includes a support member having a primary pivot pin carrying side-by-side longitudinally extending range and speed shift quadrants respec-tively connectible to the transmission to change ranges and speeds.  A shift mechanism with a vertically extending shift lever pivots laterally on a main pivot member which is pivotable around the primary pivot pin to allow longitudinal pivotal move-ment of the shift lever.  A guide plate contains a shift pattern cutout in which the shift lever is laterally movable from a neutral position in which latches in the shift lever mechanism prevent both quadrants from moving to a range or speed shift quadrant engaged position where one of the latches respectively releases the range or speed shift quadrant to allow pivotation thereof upon longitudinal movement of the shift lever.  The shift pattern cutout is provided with stop cutouts to require a Z shifting pattern to shift between ranges in one direction of longitudinal movement and the shift lever mechanism cooperates with the support member to require the same Z pattern in the opposite direction of longitudinal pivotation.  The shift pattern cutout further requires that the speed shift quadrant be in the neutral position for engagement with the shift lever.  A high/low lever pivotable by lateral movement of the shift lever mechanism along with longitudinal movement of the shift lever to cause pivotation of the speed shift quadrant provides additional speed shifting.  Lockout devices utilizing a cam follower mechanism and a lever arm mechanism operating off the range shift quadrant respectively prevent reverse operation and of certain speeds in predetermined ranges.

Abstract: Abstract of the Disclosure.      A horizontally reciprocable pump for dispensing heavy liquids such as lotion soaps, has an integrally molded body.  Both the inlet and outlet valves are held in place by the same spring which biases the plunger.  A hori-zontal pump cylinder is separated from a reservoir supply by a wall having a concentric horizontal inlet aperture, whose forward side is sealed by a molded rubber reverse-flow resisting inlet valve.  A radially enlarged flange about the body of the inlet valve has a tapered compression surface to bear against the end wall about its inlet aperture and a bearing surface on its opposite side.  The discharge valve, retained against a reducing shoulder inside the plunger discharge passage, is held by the smaller end of a tapered compression spring, whose larger end bears against the flange of the inlet valve.  The hollow discharge plunger is retained slidably within the cylinder by a pair of split bushings which, upon removal, permit complete disassembly and servicing of the pump from its forward end.  This allows adaptation for wall mounting, or mounting beneath a supply reservoir, or as an outlet from a remote supply source.

Abstract: ABSTRACT OF THE DISCLOSURE          The method is effective for separating substantially all of the aluminum from an article composed of an aluminum part bonded to a ferrous metal part.  The article, such as a die cast aluminum engine cylinder block including one or more cast iron cylinder sleeves, is immersed in a molten salt bath maintained at a temperature above the melting point of the aluminum to melt and flow away from the cylinder sleeve, while maintaining the cylinder sleeve out of contact with molten aluminum accumulating in the bath.  The resulting substantially aluminum-free sleeve is removed from the bath and residual salt on the exposed surfaces is removed, such as by washing with a hot detergent solution and rinsing with hot water.  If the cylinder sleeve is acceptable for reuse, the salt bath is maintained at a temperature below about 1340°F in order to prevent deterioration of the metallurgical properties of the sleeve.
