This invention concerns improvements to procedures to splice yarns (20-21), whether textile yarns or otherwise, the splice being obtained by coupling two single untwisted yarns (20-21) and by reconstituting the twists thereafter, by which improvements a part of the single yarns (20-21) is untwisted until twists of a sign opposite to the sign of the original twists have been imparted, such part the...

A continuous marine pipe laying system utilizes two rollers to overbend and straighten pipe as it is unwound from a reel. A support arm is pivotally connected to the axis of rotation of said reel and first and second roller arms are pivotally connected to the support arm at a point spaced from said axis of rotation. During use, the first roller is positioned at a point adjacent the pipe substantia...

The inner ends of cover-supporting ribs of an umbrella are pivotally connected to a rib carrier which is longitudinally slidable in a hollow shaft by means of a handle extending out through a longitudinal slot in the shaft. The rib carrier is slidable by means of the handle between a closed position in which the rib carrier is near the lower end of the shaft and the rib members together with the c...

The umbrella, particularly for use by an angler, comprises a rod with extendable frame with a protective screen fixed to it. Along one side, the screen is provided with an extension panel which can be placed in a vertical position, with its end secured to the ground. - The rod is arranged vertically or at an angle to provide added protection against wind or driving rain. The frame and screen may d...

A retraction seal (32) for a disc brake is disposed within a caliper groove (34). The retraction seal (32) cooperates with a forward wall (42) of the groove (34) to define a space (72) which substantially prevents the retraction seal (32) from engaging a radially inner edge (80) of the forward wall (42) during braking, thereby preventing nibbling of the retraction seal (32).

A method for reducing hysteresis in synthetic rubber stocks containing carbon black includes the step of mechanically compounding carbon black with a rubber selected from the group consisting of emulsion and solution styrene butadiene rubber and blends of each with and without 1,4-polybutadiene rubber to form a masterbatch containing less than 100 parts of rubber, adding additional parts of the ru...

Resin fiber matrix compositions comprised of reinforcing filaments and curable polyaddition products of epoxy prepolymers and diamines provide high compressive strength composites when interleafed with elastomermodified curable epoxy prepolymer interlayers.

Vulcanizable rubber compositions and articles such as tires having improved metal adhesion and metal adhesion retention to brass and brass-plated metallic reinforcement. The improvement comprises substituting at least about 10.0 parts by weight of a halogenated rubber for non-halogenated rubber present in the vulcanizable rubber composition. The non-halogenated rubber can be natural or synthetic o...

The wall panel according to the present invention and designed to cover doors, interior surfaces, furniture, white rooms such as surgical rooms, working rooms for microprocessors, laboratories, hygienic locals for animal breeding, etc. has a shape such that the wall panel contains a support panel made of uncombustible asbestos cement, preferably pearlitic asbestos cement as well as an adhered or o...

A fine powder is prepared by directing a high velocity stream of molten droplets at a repellent surface. Droplets which impact the surface are fragmented and solidified to form a very fine powder having smoothly curvilinear surfaces and diameters less than about 10 micrometers.

A pharmaceutically or veterinarily acceptable amphipathic, non-cross linked linear, branched or graft block copolymer, which has a minimum weight average molecular-weight of 1000, in which the hydrophobic component is biodegradable or hydrolytically unstable under normal physiological conditions, and the hydrophilic component may or may not be biodegradable or hydrolytically unstable under such co...

An electronic theft detection system has a transmitting antenna and a receiving antenna located on the floor and overhead of a passageway being monitored. The antennas have conductors extending along and crossways of the passageway in staggered arrangement to provide system sensitivity for different paths of egress and different planes of orientation of resonant circuits to be detected. The transm...

An alarm system used in conjunction with a circuit breaker panel box indicating the presence of an overload condition. At least one sensor is provided in proximity with the circuit breaker box but is not physically connected thereto. This sensor senses various parameters which are inherent in an overload condition or which are produced by various circuitry connected to the circuit breaker which ar...
