The apex end of a tape-reinforced balloon envelope is clamped between two segmented clamping rings which are mounted on a disc-shaped base member. The joint between the two segmented clamping rings is sealed by means of two resilient O-rings which function both as a gas seal and as a mechanical clamp for the reinforcing tapes and the balloon envelope. The O-rings rest in parallel grooves cut in the lower segmented ring and are compressed by matching tangs that project from the upper segmented ri...

An elastic balloon mounted on a hollow valve body which projects from the mouth of the balloon neck and is open axially only at its open end, with radial passages in the valve body being normally sealed by elastic engagement of the balloon neck therearound, is inflated with gas under pressure supplied to the interior of the valve body through a nozzle structure engaged by the valve body and functioning to prevent the escape of such gas from the valve body except into the balloon. The nozzle stru...

A knot tying tool, for use with a balloon having a body and a neck integrally formed therewith, comprising an elongate member having an upper surface and a lower surface, first and second longitudinally opposite ends, first and second narrow slots extending inwardly from the first end of the elongate member, and a recess in the upper surface formed generally about the second slot. The first slot receives a portion of the neck generally at its base. The second slot receives the free end of the ne...

A polyisoprene-neoprene latex in combination with a plasticizer is used to fabricate meteorological balloons.

A wrist band construction (10) for connecting at least one helium filled balloon (100) provided with a tether (101) to the wrist of a child wherein, the wrist band construction (10) includes a wrist band member (20) fabricated from a strip of heavy material (21) and provided with a pivoting D-ring member (30) that is adapted to make audible contact with a pair of metal rods (40) (40) disposed on the wrist band member (20) on the opposite sides of the D-ring member (30).

An inflatable medical balloon comprises a polymer matrix material and a plurality of fibers distributed in the matrix material. The plurality of fibers operatively adhere to the matrix material and provide reinforcement thereof. The fibers may be parallel or angularly oriented relative to the longitudinal balloon axis, and may be helically disposed thereabout. The fibers may be composed of material which has a greater tensile strength than the matrix material. The fibers may be microfibers forme...

An apparatus for selectively inflating multiple balloons simultaneously, sequentially, or in random order include a housing for storing pneumatic and electrical control devices and gas conduits. Ports are formed through the housing and each having a nozzle secured thereon. One end of one gas conduit is connected to an external source of pressurized gas and another end is in communication with the ports. An actuator is associated with each port for selectively actuating the delivery of pressurize...

A saddle connector for attaching an amusement balloon to the upper end of a carrying rod (stick). The saddle connector includes a slotted post and four arms radiating outwardly and upwardly from the upper end of the post. A tail area of the balloon can be extended downwardly through spaces between the arms and then around the post to attach the balloon to the connector.

A release fitting for releasably holding at least one line to at least one item, the release fitting having a first body part, a second body part, and a third body part, the first and second body parts pivotably secured to the third body part, a bolt with a first bolt portion connected to a first portion of the first body part and a second bolt portion connected to a first portion of the second body part, at least one pin suitable for attaching thereto the at least one line, the first body part ...

A catheter having first and second inflatable balloon structures with a valved coupling permitting the balloon structures to be separated while remaining inflated.
