Abstract: An appliance for applying a dynamic pressure wave against an extremity is disclosed. The appliance includes an inflatable cylindrical tapered cone chamber which is adaptable for surrounding the extremity. The cone chamber has a larger diameter outer end and a smaller diameter inner end and can be divided into a plurality of longitudinally extending tubular chambers. When inflated, the cone is sufficiently large and rigid to surround the extremity and prevent an exterior pressure from being applied thereto. An inflatable sleeve chamber encloses the cone chamber. The sleeve is formed of a bag-shaped bladder open at one end and closed at the other end. When inflated, the sleeve chamber defines an internal space small enough to exert a compressive force on the exterior of the cone and the extremity enclosed therein.

Abstract: A method of and mold for embedding a tubular member within a casing wherein the mold compensates for variations in length of the tubular member. The mold is a two-member structure wherein one of the members is provided with a cavity for receiving the tubular member and the casing. The cavity is closed at one end by a movable ring insert which moves relative to the assembled relationship of the tubular member within the casing to compensate for any length variations.

Abstract: A source of pressurized gas is attached to a dynamic pressure wave appliance. The pneumatic control circuit connects the source of pressurized gas to a first chamber of the appliance. When the pressure in the first chamber reaches a first predetermined level, a valve seals the first chamber and connects the source so as to inflate a second chamber about the first. When the pressure in the second chamber reaches a second predetermined level, a valve permits the first chamber to deflate while continuing to connect the second chamber for inflation. A valve for sealing the inflated sleeve discontinues the inflation of the sleeve when the pressure therein reaches a third predetermined level. The sequence of operation of the pneumatic control circuit will cause a suitable dynamic pressure wave appliance to apply a pressure to a human or animal extremity which begins at the most distant end and travels up the extremity in the nature of a pressure wave.

Abstract: The embodiment shown and described is a rattle for infants for attachment to the wrist, and in general resembles a wrist watch in appearance. It includes a casing of sheet material containing a quantity of small pebble-like translucent pieces of multi-faceted hard plastic, glass, or the like capable of rattling around creating the noise attributed to an infant's rattle. Since attachment by straps to the wrist not only militates against loss but also the infant's arm movements automatically effects the desired noise making. Another feature is coloring of the translucent pieces or prisms and forming them with facets for catching, refracting or reflecting the light's rays for visual interest. Around the periphery is an alphabet containing flange and the lens has a manual pointer for use with the alphabet affording an educational feature.

Abstract: A lubricator for an angle drive attachment for pneumatic rotary tools is disclosed. An output shaft of the angle drive attachment is surrounded by a stationary lubricating sleeve. The lubricator can include an upper portion and a lower portion formed of different absorbent materials. The upper portion can be formed of a highly absorbent material such as felt so as to act as a reservoir and reabsorb lubricant which has been thrown off of the gears while the tool is in operation. The lower portion of the lubricator can be formed of a less absorbent porous material such as open cell styrofoam to slowly meter the lubricant onto the gears through capillary action. Alternatively, the angle drive lubricator can be formed of a single piece of absorbent material.

Abstract: A pipe saddle has a pipe supporting cradle connected to a base portion by a web. This base portion includes flanges and is adapted to slidably rest on a supporting surface. Brackets mounting the flanges to the supporting surface permit the saddle to slide between the supporting surface and the brackets in the direction of the axis of the supported pipe, but restrict motion in all other directions. A relatively low coefficient of friction element is removably inserted in a cavity formed in the bottom of the base portion and extends below the bottom surface to engage the supporting surface. The pipe saddle can include a drain channel formed in the upper surface of the cradle and a slot formed in the web to accept a pipe strap.
