Abstract: ZINC-ALLOY COATED FERROUS PRODUCT RESISTANT                TO EMBRITTLEMENT                      Abstract of the Disclosure This invention is directed to an improved zinc containing metallic coated ferrous product, particularly sheet and strip, which is resistant to intergranular penetration by zinc and embrittlement of the ferrous base.          Use of such zinc containing metallic coated ferrous product in elevated-temperature service, such as found with certain appliances and automotive exhaust components, is enhanced by the coated products of this invention.  The resistance to embrittlement of the zinc containing metallic coated ferrous base, when subjected to elevated service temperatures, is achieved by the use of a high-phosphorus containing steel base.  For a plain carbon steel base, a phosphorus content of at least 0.020% by weight, preferably at least 0.030%, and more preferably at least 0.039% was found sufficient to render such zinc-alloy coated ferrous base resistant to embrittlement by zinc.         By use of such high phosphorus ferrous base, for the reception of a zinc containing alloy coating, an improved metallic coated ferrous product has been found which resists intergranular penetration by zinc and embrittlement of the ferrous base.  Such coated product has extended service life at temperatures above about 450°F (232°C) and when restored to room temperature possesses a high degree of ductility.

Abstract: ABSTRACT           A capacitance sensing circuit utilizes an operational amplifier connected in a comparator confi-guration.  The capacitance to be measured is connected to one input of the operational amplifier and is also connected to the output of the operational amplifier through a resistor to form a free-running multivibra-tor.  The period of the multivibrator output depends upon the value of capacitance being measured.  A switch-ing transistor is connected to the output of the opera-tional amplifier to cause a changing current output signal.  The output signal is obtained as a change of current in a current sensor connected to the collector of the transistor.

Abstract: A B S T R A C T     The pre-fabricated pouring outlet (2) in a lid (1) for cans containing carbonated drinks lies basically at an angle of 0 or 90° to the rolling direction (x) of the sheet from which the lid is made. The surface (3) of the lid features at least one ring-shaped stiffening groove (6) which points towards the can interior, is concentric with the periphery of the lid and is interrupted in the region of the pouring outlet (2). The diameter (d) of the groove (6) is 65-80% of that of the nominal diameter (D) of the can.     The stiffening groove raises the resistance of the lid to-wards pressure from inside the can by about 10%. This means that, when manufacturing a lid which has to withstand a specific pressure from inside the can, and using the same material, the thickness of the lid can be reduced to save material.

Abstract: ABSTRACT           The disclosure is directed to a multiple zone liner system for the cylindrical shell of a ball mill.  The liner system comprises a plurality of liner sections which are con-structed for mounting on the inner shell surface of the mill in sequential relation along its rotational axis. Each liner sec-tion is formed with a plurality of elevated ridges disposed in substantial alignment with the shell access, and which are cir-cumferentially spaced therearound to define a comminuting sur-face.  Each ridge defines a lifting surface that is disposed at a predetermined angle relative to a radius of the shell, and each ridge has a predetermined lifting dimension.  The number of ridges of each liner section increases from section to sec-tion from the inlet to the outlet of the mill.  The angle of the lifting surfaces of the ridges also increases from section to section toward the mill outlet.  The lifting dimension of the ridges decreases from section to section from the mill inlet to the outlet.  The result is a liner system capable of comminuting ore with greater effectiveness and efficiency.

Abstract: ABSTRACT OF THE DISCLOSURE      A plate spring is formed to have a "spider-like" con-figuration with pairs of bent "spider leg-like" flexible fingers.  The spring is fixed to the top of a rocker arm shaft mounting bracket so that each pair of fingers strad-dles the rocker arm shaft and biasingly contacts a lateral surface of a rocker arm pivotally mounted on said shaft. The fingers have a length adequate to allow for mass pro-duction tolerances while simultaneously biasing the rocker arm uniformly along the rocker arm shaft preventing any unwanted uneven wearing of the shaft or rocker arm.  The spring may be replaced simply by removing a single bolt.

Abstract: ABSTRACT An impact device, more particularly a needle gun is disclosed.  The gun comprises a housing which may be cylindrical and which contains a comparably shaped rotatable member mounted for rotation about an axis parallel to but ec-centric with respect to the axis of symmetry of the cylindrical housing.  One or more radially disposed holes in the  rotatable member contain balls which are forced outwardly by centrifugal force as the rotatable member is rotated by, for example, an electric motor.  Because of the eccentric arrangement there is one angular position at which there is present a relatively large space between the rotatable member and the housing and when a particular one of the holes reaches this angular position the ball screwed in the hole is permitted to move out further from the rotatable member.  By arranging elongate impact members or needles with their ends at this angular position the balls are caused to impart energy to the needles and move them longitudinally.

Abstract: Abstract Procedures are presented for isolating the major outer membrane protein of Chlamydia trachomatis.  The isolated protein is a species specific antigen which comprises about 60% of the C. trachomatis cell outer membrane structure.  The protein has a molecular weight ranging from about 38,000 to 44,000 daltons, with a mean molecular weight of about 39,500 daltons.  The protein antigen is purified from C. trachomatic cells by first extracting the cell contents with a mild anionic detergent, preferably sarcosyl, to leave a residue of intact outer cell membranes.  These outer cell membranes are then extracted with a strong anionic detergent, preferably sodium dodecyl sulfate, which solubilizes the 39,500 dalton antigen.  The antigen is then purified by hydroxlapatite chromatography. The antigen is species specific for Chlamydia trachomatis and may be utilized in assaying Chlamydial infection in mammals.

Abstract: ABRIDGEMENT    The higher the voltage applied to an electrical device comprising a PTC conductive polymer, the more likely it is that intermittent application of the voltage will cause the device to fail. According to the invention, the likelihood of such failure is substantially reduced by irradiating the PTC conductive polymer so that it is very highly cross-linked, for example to a dosage of at least 50 Mrads, preferably at least 80 Mrads, especially at least 120 Mrads.  In this way, for example, it is possible to make a circuit protection device which will continue to provide effective protection even after repeated exposure to a voltage of 200 volts.
