Abstract: ABSTRACT OF THE DISCLOSURE           A pneumatic tire having a reinforcing belt which includes a first ply of cords formed from a synthetic material having a high modulus of elasticity and a second ply of metallic cords. The first ply has a width substantially equal to the width of the tread of the tire. The second ply has a width between one-fourth and three-fourths of the width of the tread. The second ply reinforces the median region of the tread. Each cord of the first ply intersects the median equatorial plane of the tire at a first angle of from 14° to 30°; each cord of the second ply intersects the median equatorial plane of the tire at a second angle of from 22° to 32°. The secondangle is opposite in direction from the first angle. At least one strip of cords formed from a synthetic material having a low modulus of elongation overlaps an edge region of the second ply. The foregoing abstract is not to be taken as a complete exposition of the present invention.

Abstract: ABSTRACT OF THE DISCLOSURE       Subterranean slurry mining with one or more mining nozzles which, during mining, directs a high pres-sure jet of liquid into a granular ore matrix to reduce the ore to a slurry which is thereafter pumped to the surface by an eductor pump including a high pressure eductor nozzle. The drilling and mining apparatus includes several different types of hydraulic control systems which operates at or below system pressure and allows the ap-paratus to be changed between the mining and a drilling mode. During drilling, the liquid is directed through an open foot valve and drill bit into the well cavity being drilled to wash the cuttings to the surface at which time the mining and eductor nozzles are closed. During mining the control systems close the foot valve and control the opening of the mining nozzle (or nozzles) and eductor nozzle.         When the control system includes one or more control conduits that extend to the surface, the system may be used to modulate the eductor nozzle, and depending upon the control system being used to selectively open or close the mining nozzle, thereby controlling the pressure or draw-down in the cavity. Self-activating control systems are disclosed and are responsive to differences be-tween system pressure and cavity pressure when the foot valve is closed to modulate the eductor nozzle. Other self-acti-vating control systems may be used to selectively open and close a pair of mining nozzles without modulating the eductor nozzle, or with provision for modulating the eductor nozzle.                   -1a-

Title: Pressure-sensitive tape having a plurality of  adhesive layers
Inventor: GOBRAN RAMSIS
IPC: G09F3/10
Filed: 1979-03-23
Granted: 1982-12-21
Abstract: Abstract A pressure-sensitive adhesive tape which not only conforms well and adheres quickly to irregular substrates but also possesses excellent shear adhesion performance.          These properties, normally mutually exclusive, are achieved through use of superposed plural pressure-sensitive adhesive strata, the outer stratum being significantly sorter than the one lying immediately beneath it.  Softness is expressed in terms of cm2/dyne for 10-second shear creep compliance.          The tapes are particularly suited for use in the prepara-tion of diaper closures and indentification labels for wash-able garments.

Abstract: ABSTRACT OF THE DISCLOSURE      An electric circuit breaker includes means for providing a predetermined delay between the initiation of a command pulse and the mechanical operation of an element of the circuit breaker in response to the command pulse.  In on-embodiment, the predetermined delay is provided between a tripping command pulse and the mechanical operation of the trip mechanism of a vacuum circuit breaker.  In this embodiment, a translatable armature is coupled to the trip mechanism through mechanical linkage including a flywheel rotatably mounted on a shaft.  The shaft is mechanically coupled to the trip mechanism wherein rotation of the shaft operates the trip mechanism.  The translatable armature is mechanically coupled to the flywheel so that movement thereof causes the flywheel to rotate through a predetermined rotation.  The flywheel includes impact imposing means extending outwardly from a major face thereof.  The shaft includes impact receiving means ex-tending radially therefrom.  In operation of this embodi-ment, following the tripping command pulse, the flywheel rotates through the predetermined rotation with a re-sulting predetermined delay.  At the completion of this rotation, the impact imposing means of the flywheel force-fully engages the impact receiving means of the shaft.  This causes the shaft to operate the  trip mechanism, causing the circuit breaker contacts to open.  Means are provided for varying the predetermined delay.  Other embodiments are disclosed.

Abstract: ABSTRACT                  COATING PROCESS MASK      This invention describes a method of masking a workpiece to prevent the adhesion of a deposited tightly adhering conformal coating formed from the condensation of a vaporous diradical such as paraxylylene on selected portions of the workpiece.  Specifically the process of the in-vention requires the covering of the areas of the workpiece, to which adhesion is not desired, with a non-polymerizing hydrocarbon and placing the covered area in close contact with an open cellular material containing a predominance of interconnecting cells which provide  a large surface area for condensation of the unwanted con-densate of the diradical, exposing the workpiece to the vaporous diradical, removing the workpiece from the open cellular material and immersing the workpiece in a solvent for swelling and dis-solving the hydrocarbon covering.
