Title: Implantable artificial sphincter system
IPC: A61F5/37
Filed: 1990-07-19
Abstract: IMPLANTABLE ARTIFICIAL SPHINCTER SYSTEM                         Abstract This invention relates to an implantable artifi-cial sphincter system for reversibly occluding a body passageway, which system includes occlusion means, pump means, and the unique feature of a fluid capacitor disposed on a control assembly for the system, which is capable of increasing volume under fluid pressure.  The fluid capacitor is connected with the occlusion means in such fashion that said occlusion means will remain substantially inflated during short, but significant, pressure increases, but will at least partially deflate upon the advent of prolonged but moderate pressure increases on the body passageway.  While in its prefer-red embodiment no other fluid containing component is needed, if desired a volume compensator can also be included in the system.  A valve preferably of the magnetic type can also be included for activating or deactivating the system.

Title: System and method for vertically flushing a steam generator during cleaning operation
Inventor: FRANKLIN RICHARD D
IPC: F22B37/48
Filed: 1990-12-21
Abstract: W.E. 55,513 Abstract of the Disclosure Both a system and a method for removing sludge and debris from the interior of the secondary side of a nuclear steam generator is disclosed.   The method comprises the steps of introducing a sufficient amount of water in the secondary side to submerge at least the tubesheet, generating a succession of shock waves in the water by means of pulses of pressurized gas to create shock waves that loosen the sludge and debris, and vertically flushing the interior of the secondary side by suctioning water off from the bottom portion of the steam generator while simultaneously forcefully spraying water from the top portion of the generator over the bundle of heat exchanger tubes in order to remove the sludge and debris  loosened by the shock waves.   To conserve the water used in the flushing operation,  the water that is suctioned off from the bottom portion of the steam generator is filtered and de-ionized and re-introduced through hoses as the top portion of the generator which forcefully directs water downwardly through the bundle of heat exchanger tubes and against the tubesheet. The invention greatly enhances the effectiveness  of pressure pulse,  water slap and water cannon cleaning methods in the secondary sides of nuclear steam generators.

IPC: A61C8/00
Filed: 1991-06-18
Abstract: Abutment posts, gingival collars, and universal adaptors along with their fixation screws that are used for insertion into dental implants are revealed. The universal adaptor has at one end an external hexagon post, cylindrical post, or other means of varying dimensions of such a nature as to fit into several different types of manufactured implants with various dimensions and internal thread diameters. The adaptor is universal in that it matches to many different shaped, sized, and styled implants, and standardizes their restoration with uniform gingival collars and abutment posts. A small flange which tapers from the dimension that matches the individual underlying implant to a standardized size at its free end. An external post, octagon in shape, extends from the flange towards the free end. A gingival collar of varying sizes, which extends from the top of the flange to the height of the gingival tissue, is used to bring the restoration of the implant into the oral cavity. It tapers from the open end at the flange of the universal adaptor to a larger standardized size in order to more naturally represent the size and shape of a natural tooth root. It has an internal sleeve, extending from the open end at the adaptor to the free end at the abutment insertion which has an octagon shape to receive the octagon posts of the "adaptor" and the abutment post. In some instances, the abutment post has at one end an external octagon post to be inserted into the gingival collar. It may be designed in a variety of angulations to upright an otherwise angulated implant that is not parallel to other teeth or implants. The post tapers from the gingival collar at the open end to its free end and has at its free end one or more sockets to receive fixation screws to affix the abutment post to the universal adaptor and to affix a fabricated crown or coping that has a flaring section at its open end. The crown may be affixed to the post either by cementing it on to the abutment post or by screwing it into the socket in the post.
