Abstract: Abstract of the Invention An aqueous dispersion of a rubber latex and dihydroxy-phenol-aldehyde resins consisting essentially of resorcinol-aldehyde resins and catechol-aldehyde resins is useful in forming an adhesive bond between reinforcing ma-terials such as nylon and rubber compounds.  It is essen-tial that the catechol-aldehyde resin be made separately from the resorcinol-aldehyde resin with which it is later mixed in solution.  The dispersions of this invention re-sult in improved aged adhesion and lower fabric stiffness than the older resorcinol-formaldehyde latex disperions.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of forming a torsion bar wherein steel, preferably an alloy steel of medium carbon content, is formed in the desired size and shape and is through hardened for providing a desired core hardness.  The case of the bar is then hardened for transforming austenite in the case into martensite causing the case to expand thereby inducing high compressive stresses near the surface with the com-pressive stress decreasing radially inward of the surface.          The core of the bar is retained below lower transformation temperature for resisting expansion of the case thereby inducing hoop and axial compressive stresses and radial tensile stressed in the case.  The hardened bar is then cold worked by twisting and releasing the bar at least twice for applying a torsional stress in the angular direction of the bar loading which presets the bar by twisting it beyond its initial yield strength for redistributing the stresses and inducing a residual torsional stress therein in a direction opposite to the preset direction.        A torsion bar formed by the method of the present invention is also disclosed.     -1a-

Specifically, shaped closures having concave interior portions and resilient sealing liners are supplied to an inspection station comprising one or more female inspection nests for receiving individual closures and one or more respective male inspection heads for insertion into the-concave portions of respective closures.  The inspection heads are pro-vided with exterior shapes approximating the interiors of ideal closures so that penetration into the closure indicates the conformity of the closure to the ideal.  Preferably, the inspec-tion head is connected to a source of pressurized fluid for test-ing both the depth of penetration and the adequacy of the sealing ring.  Closures capable of maintaining a seal at a predetermined level of pressure are automatically passed and closures failing to meet this test are automatically rejected.  A preferred embodi-ment for accepting crown bottle caps from a plurality of lining machines is described in detail.

Abstract: ABSTRACT OF THE DISCLOSURE A vibrator capable of reaching the natural frequency of stored products such as wood chips assumes a configuration capable of attachment to rail cars or storage hoppers. The vibrator may be used to aid in the discharging of stored products or may be used to assist in the packing of stored products. The eccentrics of the vibrator attach to a cylindrical casing with fixed jaws. The vibrator's cylindrical casing and jaws are constructed to allow the angle iron or "I" beam on which the vibrator attaches to be in close proximity to the rotating eccentics, thereby effectively imparting the vibrational frequency to the storage facility. The cylindrical casing and jaws are affixed to the storage facility by dead end bolts, sleeves and locking bolts. A portable pump unit is designed in conjunction with the vibrator to hydraulically or pneumatically drive the vibrator and give the operator flexibility as to where the operator can position the vibrator.
