Abstract: A needle assembly for a medication delivery pen having a 31 gauge needle cannula that reduces penetration force during an injection process resulting in less pain to the patient without causing any loss in performance or structural integrity.

Abstract: A pen needle having a cylindrical hub including a distal section that is received in a needle holder and a proximal section having threads that mate with a pair of lugs in an adaptor mounted on a medication delivery pen. The distal end of the pen needle includes a plurality of splines that mate with splines in the needle holder to prevent the pen needle from rotating within the needle holder and aid in threading the pen needle onto the adaptor. The pen needle is fully received in the needle holder to shield the proximal point of the pen needle and can only be removed from the needle holder by using the adaptor or a cartridge retainer having the proper pair of lugs thereon.

Abstract: A pen needle dispenser having a cover rotatably mounted on a circular shaped container having a plurality of cavities, with each cavity dimensioned to receive a pen needle assembly with or without shields. The cover includes a slot that is rotated into alignment with one of the cavities in the container to provide the user with access to one unused shielded pen needle and thereby permits the pen needle to be mounted on a medication delivery pen. After use the used unshielded pen needle is returned to and locked in the cavity. Then, the cover is rotated until the slot is aligned with another cavity containing the next unused shielded pen needle to be used during the next injection. The pen needle dispenser prevents the cover from rotating the slot back to cavities containing used pen needles.

Abstract: A pen needle magazine dispenser designed to be received and carried in a cap of a medication delivery pen. The dispenser having a cover rotatably mounted on a circular shaped container with a plurality of cavities, wherein each cavity is dimensioned to receive one pen needle. The pen needle being of a type that is forced fit into an adaptor on the pen using threads on the pen needle and corresponding threads in the cavity. The cover includes a slot that is rotated into alignment with one of the cavities in the container to provide the user with access to one unused pen needle and thereby permit the pen needle to be mounted on the pen. After use the used pen needle is returned to the cavity and the cover is rotated until the slot is aligned with another cavity containing the next unused pen needle to be used during the next injection.

Abstract: An adjustable shelf for a paint colorant dispensing station comprises at least two platforms rotatably mounted on a pair of brackets. A pair of stops restrain the rotation of the shelf between two positions. One of the platforms is substantially horizontal and disposed beneath a dispensing head in one of the positions. The other platform is substantially horizontal and disposed beneath the dispensing head in the other of the positions. Each platform is adapted to hold a paint can. Each stop is adjustable by rotating the stop relative to the shelf. The rotation causes a threaded rod to extend from or retract to the element that supports the stop. A locking mechanism is provided to selectively restrain the shelf against rotation when the shelf is in one of the two positions.

Abstract: The disclosure is directed to a fault tolerant fluid flow apparatus which will continue to function during a malfunction of a valve utilized therein. The disclosed apparatus uses parallel arms, each containing serially connected valves and may be incorporated in a manifold. One embodiment utilizes an inlet and outlet switching valve so that one of the parallel arms can be closed off from fluid flow for service of a valve therein.

Abstract: Apparatus for manipulating at least two fluid flow circuits comprising a manifold, and a valve stem assembly with at least two stages in series, with each stage comprising a valve relief for communicating with at least two inlet and outlet ports, and a seal for blocking off or isolating a port. The apparatus of the invention allows at least two fluid flow circuits to be connected to the manifold in a parallel configuration to operate in a redundant manner. If the conduit or a fluid control or monitoring device within a circuit fails or requires maintenance, that particular circuit may be isolated from the process flow system by the multiple flow directing capability of the apparatus. Use of the apparatus of the invention enables the removal of valve devices or conduit in a circuit for repair or replacement without interrupting the on-line process fluid flow.

Abstract: A patio pool having an outer wall fixedly mounted on ground level undisturbed earth and an inner wall fixedly mounted to undisturbed earth on the bottom of an excavation, the inner wall extending upward from the excavation to a height such that the top edge thereof is at the same level as the top edge of the outer wall thereby providing a pool whose total depth is partly a result of the excavation depth and partly due to the wall portion extending above ground level, the pool has struts fixedly secured to the inner wall for stabilizing the total wall structure, and a filler material positioned within the space between the inner and outer wall and below a plurality of deck slats connecting the top edges of the inner and outer walls for stabilizing the wall construction.

Abstract: A boom is disclosed having an elongated flexible skirt confined between and secured to a series of floats arranged in pairs. The floats of each pair are identically formed, and are oppositely arranged at opposite sides of the skirt, to which they are secured in such fashion as to dispose the upper edge portion of the skirt above the water level. The lower edge of the skirt extends downwardly below the water level a suitable distance to confine pollutants, such as oil, floating upon the surface of the water. A tension member extends along the bottom edge of the skirt, in the form of a flexible cable. The tension member is retained in position through passage thereof within longitudinal bores provided in clamp assemblies regularly spaced along the length of the skirt. Each clamp assembly comprises complementary metal clamp elements, particularly shaped as to permit their being formed as extrusions.

Abstract: A swimming pool is provided with side walls made up of a plurality of panels each embodying upper and lower receptor beams in the form of oppositely facing channels supporting the upper and lower horizontal edges of plywood sheets, with bracing members located between the vertical edges of the plywood sheets and secured at their upper and lower ends to the receptor beams so as to support each sheet about the entire peripheral edges thereof. The panels are secured together in selected arrangements by fasteners and splice plates at the adjacent ends thereof to establish a unitary structure of exceptional strength which may be made up of a limited number of inexpensive elements adapted to be assembled and erected with a minimum of labor.

Abstract: A crawler is disclosed for traveling through a workpiece such as a pipeline and inspecting the same for defects. The crawler is a completely self-contained, self-propelled and self-operated vehicle adapted to travel through a pipeline, stop at particular locations such as a girth weld between adjoining sections of pipe, inspect the weld, for example by X-raying it and then proceed onto the next location to be inspected.
