Title: Method and antenna for providing an omnidirectional pattern
Inventor: PHILLIPS JAMES PATRICK
IPC: H01Q21/24
Filed: 1996-04-26
Abstract: The present invention provides a method (400) and antenna (100) for providing an omnidirectional pattern. The antenna (100) is smaller than prior art omnidirectional antennas with the same bandwidth. The smaller size is made possible by the use of at least one capacitive element (104) at a discontinuity in the loop (102). The pattern is balanced and therefore the omnidirectionality is maintained by the current maximum (110 and 112) that are created by the capacitive element (104).

Abstract: A method for making a carbon lined vascular graft wherein a polymeric carbon compound and a polymeric compound are co-extruded through a mandrel and die assembly to form a vascular graft having carbon as an integral component of its intraluminal or exterior surface is presented, along with the carbon containing graft which results from the method. A divided preformer comprising two hollow concentrical cylinders is used to form a dual compound billet for extrusion. Alternatively, the polymeric carbon compound may be used to fill both cylinders of the divided preformer to form a single compound billet which is extruded to present a carbon containing polymeric graft having uniform carbon polymeric material throughout the wall of the graft. A preformer having multiple dividers which thereby forms a billet having multiple layers wherein one of the layers contains a carbon element way also be used as part of the inventive method. A time-releasable bioactive substance may be incorporated into the vascular grafts resulting from the inventive method.

Title: Crown-and-root reconstruction assembly made of a composite material with a modulus of elasticity varying along a gradient, and method for making same
Inventor: MANEUF BERNARD
IPC: A61C13/30
Filed: 1995-11-21
Abstract: A crown-and-root reconstruction assembly made of composite materials with a modulus of elasticity varying along a gradient. The assembly comprises a physiological securing peg (4) and a crown reconstruction base (1) made of partially or completely light-conducting material. The connection between the crown reconstruction base (1) and the peg (4) is achieved by polymerising the material of the base under an isostatic charge. The forming process may be completed by manipulating the material with the fingers through a forming membrane (22) to prevent any gap developing at the interface (10) between the root (8) and the crown reconstruction base (1). A helical arrangement of the fibres (5) of the peg (4) ensures that the modulus of elasticity is close to that of the natural dentine, regardless of the angle of incidence at which the reconstruction is stressed.

Title: Pulley
Inventor: TANAKA YASUHITO
IPC: F16D41/067

Abstract: A pulley has a hub fixed to a rotating shaft. An outer wheel is disposed on the outer periphery of the hub and around which a belt is suspended, and a unidirectional clutch is interposed between the hub and the outer wheel. A cam face for forming a wedged space of the unidirectional clutch is formed at the inside of the pulley, whereby the unidirectional clutch is switched between a free state and a locked state through the rotational variation of the hub which rotates integrally with the rotating shaft to reduce the transmission of the rotational variation from the hub to the outer wheel. Further, the unidirectional clutch can operate stably without suffering the effect of the rotational centrifugal force.
