Assignee:

Certain-teed Corporation - Valley Forge PA

International Classification:

F16L 2100

US Classification:

285419

Abstract:

Fittings and methods for manufacturing fittings for piping are disclosed. The fittings are assembled from three identical molded pieces joined along longitudinal edges. Interfitting pieces form the joints between the sections and serve to draw the sections together during assembly and ensure roundness of the fitting. The technique is especially useful for the manufacture of fittings such as well screens, of synthetic polymeric materials.

International Classification:

A61B 500
A61M 500

US Classification:

128630

Abstract:

A personal health care system utilizing a unitary command center having a computer for receiving, storing, processing, and transmitting information, and a plurality of interfacing ports. Each interfacing port is adapted to accept a plurality of different patient monitoring sensor modules, a plurality of different accessory modules, and a plurality of different therapy-providing modules. An accepted module is electrically interconnected to the data processor for sending and receiving information therebetween. The data processor includes means for providing operating instructions to the sensor modules, accessory modules, and therapy-providing modules. Each sensor module senses and provides information on a condition of a patient and each therapy-providing module provides a therapy to the patient. The data processor monitors the information provided by the sensor modules and controls provision of the therapy to the patient.

International Classification:

E21B 4308

US Classification:

166234

Abstract:

A well screen is provided, for insertion into a well, for screening out sand and other particles from the well, and for connection at its upper end to a pipe for delivering water or other liquid up from the well, with the well screen having a skin with slits in it for passage of liquid therethrough, and with the skin having internal rigidifying supports. The skin is provided with a surface area increase in the form of undulations preferably of sawtooth configuration throughout its surface, and is preferably thinwalled. The screen is preferably of thermoplastic construction.

Paul Brothers - Chadds Ford PA
William L. Muir - Northeast MD

International Classification:

A61F 212

US Classification:

623 8

Abstract:

The instant invention is directed to a mammary prosthesis injector. The injector comprises a hollow tube having an opening at one end thereof. A bag for holding the prosthesis and reducing friction between the tube and the prosthesis is located, in part, within the tube. A mechanism for pulling the bag from within the tube is slidably mounted on the exterior of the tube and engages the bag. The prosthesis, which is held within the bag which is within the tube, is ejected from the tube and through the opening when the pulling mechanism is slid along the exterior of the tube.

International Classification:

A61F 500

US Classification:

602 5

Abstract:

A dynamic splint is provided which applies a bias force across a body joint with a magnitude which is adjustable at a pivot in the splint. At the pivot, a joint enclosure is provided to house a coiled leaf spring having one end connected to a movable adjustment mechanism. The relative magnitude of the bias is indicated by an indicator bearing numeric markings which moves with movement of the adjustment mechanism. A pin look mechanism is provided for locking pivoted strut members of the splint to prevent relative movement thereof about the pivot.
