Abstract: In a shaft seal (1) with a solid shaft seal ring (4) manufactured from possibly filled polytetrafluoroethylene or materials of a similar kind, and an axial limb (6) situated at the outer periphery and forming the seating surface, annular encircling grooves (7), preferably with a triangular, sawtooth-shaped cross-section, are machined into the seating surfaces of the receiving hole (2) of the housing. When the shaft seal ring (4) is pushed in, the polytetrafluoroethylene flows into these grooves under the pressure applied, with the result that the shaft seal ring (4) is secure against axial displacement and, with a good press fit, provides optimum static sealing in the region of the seating surface. An additional, elastically deformable projection (11) at the outer periphery of the shaft seal ring (10), which snaps into a corresponding groove (7) in the seating surface of the receiving hole upon assembly, provides additional security for the shaft seal ring (10) in relation to axial displacement and twisting in the circumferential direction. <IMAGE>

Abstract: In order to determine and/or evaluate quality characteristics of a body of meat material (32) at least one probe (10) containing means (24) for emitting mechanical vibrations is plunged into the meat body so as to position the vibration emitting means (24) therein. The mechanical vibrations emitted by the emitting means, which may, for example, be a mechanical transducer (24), are detected by detecting means, which may also be the transducer (24). Quality characteristics of the meat body may then be determined and/or evaluated on the basis of signals generated in response to mechanical vibrations detected by the detecting means (24). As the mechanical vibrations may be emitted from a desired location inside the meat body (32) within the tissue structure to be examined, and as the window of the emitting and detecting means or transducer (24) may be arranged in good frictional or abutting contact with the meat substance of the body, the results obtained may be substantially improved compared with known methods.

Title: Self-expanding prosthesis having stable axial length.
Inventor: PORTER CHRISTOPHER H
IPC: A61F2/82
Filed: 1991-04-25
Abstract: A body implantable stent consists of two or more generally tubular, coaxial and slidably connected stent segments. Each of the stent segments is of open weave construction, formed of multiple braided, helically wound strands of resilient material. The stent is elastically deformed to a reduced radius when deployed. When released after positioning, the stent self-expands radially into contact with a tissue wall segment defining a blood vessel or other body cavity. As each stent segment expands radially, it contracts in the axial direction. To preserve a consistent length of the stent in spite of axial contraction of the segments, the axially outward and non-overlapping portions of the stent can be designed for secure fixation to the tissue wall segment, for example as radially outward flares. Accordingly, axial contraction occurs as a reduction in the length of the medial regions where adjacent stent segments overlap. Alternative approaches to maintain axial length include the addition of reinforcing filaments near the stent opposite ends to increase the restoring force, the provision of fixation hooks at opposite ends of the stent, and securing an elongate, axially directed, flexible and inextensible wire to the opposite ends of the stent.

Title: Dryer apparatus.
Inventor: WEDEL GREGORY L
IPC: D21G9/00
Filed: 1991-09-26
Abstract: A dryer apparatus is disclosed for drying a pressed web. The apparatus includes a plurality of single tier dryer sections in which successive sections dry alternate sides of the web, the web being transferred between successive sections without any open draw of the web such that the web is uniformly dried on both sides thereof while the web is restrained against cross-machine directional shrinkage. Each of the sections includes a single tier of dryers with an intermediate roll disposed between each adjacent dryer. A dryer felt extends in serpentine configuration around each dryer and roll such that the web is disposed between the felt and each dryer for drying one side of the web. The felt is also disposed between the roll and the web with the felt in direct contact with an alternate side of the web. The intermediate roll defines a plurality of circumferential grooves for diffusing boundary air following the felt that would otherwise tend to lift the web from the felt extending around the roll. The arrangement is such that inherent machine directional shrinkage of the web during drying thereof inhibits crossmachine directional shrinkage of the web during movement of the web between successive dryers.

Abstract: Selon la présente invention, un dispositif de raccordement comprend un élement de chauffage pourvu d'une couche de matériau ferrommagnétique (14), ainsi qu'un matériau fusible tel qu'une préforme de brasage (10). Le dispositif de raccordement comprend, par exemple, un manchon creux (4) composé d'un matériau thermorétractable. La préforme de brasage (10), l'élément de chauffage et le manchon creux thermoréactable (4) sont intégrés sous forme d'un dispositif à manchon de brasage autonome, de sorte que l'élément de chauffage demeure séparé des objets à raccorder et n'agit pas comme un écran total par rapport à la génération d'un courant inductif dans les objets devant être raccordés. Le dispositif de raccordement favorise ainsi un écoulement et une adhérence réguliers du matériau fusible autour de la jonction des objets. En outre, on décrit un dispositif de raccordement qui permet une inspection visuelle d'un raccordement entre des objets raccordés à l'aide du dispositif de raccordement, ce qui permet de s'assurer de l'intégrité de la jonction.
