Abstract: A B S T R A CT     A noise-preventing shock absorber adapted to suppress noise and absorb shock created by moving objects such as moving machine parts engaging mating surfaces and decelerating to zero vel-ocity within a short stroke or travel distance. The shock absorber in-cludes a unitary resilient member which is annularly shaped in plan view and provided with an axial opening, with the peripheral surface of the axial opening comprising an inner force-transmitting surface that is formed with a wavelike configuration in vertical cross section. An upper force-receiving shaft is disposed in the resilient member axial opening and has an exterior peripheral surface which is provided with a wavelike configuration in vertical cross section that mates with and is bonded to the wavelike inner force-transmitting surface of the resilient member. The resilient member is provided with a peripheral outer force-transmitting surface that is concentric with and axially offset downwardly from said inner force-transmitting surface, and which is provided with a wavelike configuration in vertical cross section. A lower force-receiving tube having an interior surface provided with a a wavelike configuration in vertical cross section mates with and is bond-ed to the wavelike outer force-transmitting surface of the resilient mem-ber. The shock absorber member can be used in a stacked arrangement to provide shock-absorbing and noise-suppressing units of various capacities,

Abstract: ABSTRACT OF THE DISCLOSURE           A plastic face shield is detachably and firmly secured to a support mounted on a helmet.  The plastic face shield has an elongated slot into which an elongated cam lobe is positioned. The cam lobe is slightly longer than the transverse dimension of the slot so that when the cam is rotated from the loose position to the tight position, it expands the slot slightly, the slot closing back almost to its original dimensions as the lobe cam goes to the locked position.  The lobe cam then holds the face shield in taught condition and the contracted slot prevents rotation of the lobe cam so that it remains locked.

Abstract: Consistencies of slurries, such as slurries of cellulose in water, are measured by immersing in the slurry a radioactive source of fast neutrons, and neutron detector at a fixed predetermined distance from the source.  The neutron count so  obtained can be used to determine slurry consistency. If a second neutron detector  is immersed in the slurry at a predetermined, greater distance from the neutron source, the two neutron counts can be used to determine both the slurry consistency and the density of the suspended material.

Abstract: IMPROVEMENTS IN METAL COATING                 Abstract of the Disclosure Ferrous metal or titanium is coated with a mixture of phosphoric acid, chromic acid and magnesium salts of these acids, and separately with aluminum flake applied as upper or lower layer with or without hexavalent chromium compound like magnesium chromate, and/or metallic magnesium, both layers being baked, to provide excellent resistance to attack.  The aluminum flake layer can also be used without the other layer.  Diffusion aluminizing of the ferrous metal before the coatings produces even better results.  Very good masking of pack diffusion aluminizing or chromizing, on any metal, to keep portions from being metallized is effected by multi-layer localized coating the lowest layer being depletion-reducing masking powder mixed with non-contaminating film-former such as acrylic resin, and upper layer or layers being of non-contaminating particles like nickel or Cr2O3 that upon aluminizing become coherently held together to form a secure masking sheath.  Aluminizing pack can then be re-used.  Film-former can be dissolved in volatile solvent, preferably methyl chloroform, in which masking powder or sheath-forming powder is suspended.  Chromizing can be performed before aluminizing for greater effects, and pack chromizing in gas-tight retort under inert gas such as argon, using low activity throw-away pack of highly diluted mixture of chromium, nickel and aluminum gives chromized coating exceptionally free of undesired oxides and of alphachrome.  Differential chromizing can also be practiced to produce thinner chromized case in desired locations.  Low alloy steel conduit can be internally chromized and/or externally chromized or aluminized to make it more desirable for use as high pressure steam boiler heat exchange tubing.  Nickel articles aluminized with deep Ni2Al3 layer that has outer skin more heavily aluminized can have aluminum correspondingly leached out from outer skin only.

Abstract: Title:          Synthetic aperture scanner for decoding a coded image produced by penetrating radiation, such as X-rays.            Abstract of the disclosure:          A system for decoding a coded aperture image of an object exposed to short-wave radiation from a plurality of point sources positioned in space in accordance with a given distribution. The coded aperture image is displayed by a cathode ray tube having its screen optically coupled to the entrance screen of an image intensifier tube. This image intensifier tube is effective to consecutively shift its entrance screen image in its entirety along a field pattern of lines. The images thus produced on the exit screen of the intensifier tube are transferred through a mask system having a transparancy pattern related to the distribution pattern of said point sources, to a detector which position wise integrates the light transmitted through said mask system.

Abstract: ABSTRACT OF THE DISCLOSURE   An electron beam tube electrostatic deflection system and method of operation is described.  The electron beam tube includes an eight-fold deflec-tor and means are provided for applying two different quadrupole correction electric potentials to selected ones of the eight-fold deflector members and for applying an octupole correction electrical potential to all eight deflec-tor members.  In the preferred embodiment, the quadrupole and octupole cor-rection potentials applied to one set of four deflector members are repre-sented by the respective values (V2c - ?),(-V2c - ?),(V2c - ?),and(-V2c - ?), and the quadrupole and octupole correction potentials applied to the second set of four deflector members are represented respectively by the values (V2s + ?), (-V2s + ?), (V2s + ?) and (-V2s + ?) where the quadrupole correction electric potential       ,                  (1) the quadrupole correction electric potential         ,                              (Z) and the octupole correction potential ? applied to all eight of the eight-fold deflector members is given by the expression                                  (3) where Azc,A2s and A4 are constants, Vx and Vy are the x and y deflection elec-tric potentials, and -Vc is the cathode voltage of the electron gun used in the electron beam tube apparatus.  In preferred arrangements, the electrostatic deflection system further includes means for applying a dynamic focusing elec-tric potential to the objective lens assembly of the electron beam tube appar-atus in conjunction with both the correction and deflection electric potentials described above.  The dynamic focusing electric potential is                                (4) where ADF is a constant and VOBJ(O) is the uncorrected value of the direct current objective lens supply voltage.  Both deflection and correction electric potentials are developed by an eight-fold deflector voltage generator which includes as its heart a novel octupole-quadrupole generator.  The corrected electrostatic deflection system can be used in a sample electron beam tube structure employing only a single eight-fold deflector assembly for deflecting with low aberration a finely focused electron beam onto any desired address point on a target plane.  Alternatively, the corrected electrostatic deflec-tion system can be employed with a compound electron beam tube apparatus of the type employing a compound coarse and fine deflector system sometimes re-ferred to as a fly's-eye type electron beam tube.  In the compound electron beam tube apparatus, the eight-fold deflector assembly is employed as the coarse deflector assembly and preferably is fabricated in two eight-fold sec-tions which are electrically interconnected.
