Abstract: An installation for temporary selective connection having fluid (in particular petroleum products) inlets and outlets comprises a set of first coupling sections (7A...7P) which move along a virtual boundary plane P which is vertical in practice, in a first direction of this plane, and a set of second coupling sections (14-1...) which move along this virtual plane, on the other side and in a second direction of the latter. Each first coupling section is connected to a first fixed section (2A...) by a deformable pipe (3A...3P) which in practice is parallel to this first direction. Each second coupling section is connected to a second fixed section (17-1...) by a deformable pipe (16-1...) which in practice is parallel to this second direction. The first fixed sections are offset parallel to the second direction and the second fixed sections are offset parallel to the first direction. These fixed sections are substantially perpendicular to the plane P. Any first coupling section can be coupled to any second coupling section.

Abstract: A fluid pump with rotary impeller is disclosed which comprises an electromagnetically driven rotary impeller levitated by localized opposed fluid forces. Levitation by localized opposed fluid forces of an impeller driven by electromagnetic forces eliminates the need for bearings and seals in the driving mechanism. This avoids the heat build-up and leakage associated with other pumping mechanisms, which can be of importance for pumping of physiological fluids such as blood. The levitating fluid forces of the present invention are auto-adjusting, such that any attempted displacement of the impeller will automatically incur a corrective change in levitating fluid forces. However, fluid force sensors and regulators could be incorporated into the present invention if desired. The invention should be of use in numerous medical and non-medical applications where the benefits of impeller levitation by localized fluid forces are apparent.

Abstract: A man-machine interface is disclosed which provides force and texture information to sensing body parts. The interface is comprised of a force actuating device that produces a force which is transmitted to a force applying device. The force applying device applies the generated force to a pressure sensing body part. A force sensor on the force applying device measures the actual force applied to the pressure sensing body part, while angle sensors measure the angles of relevant joint body parts. A computing device uses the joint body part position information to determine a desired force value to be applied to the pressure sensing body part. The computing device combines the joint body part position information with the force sensor information to calculate the force command which is sent to the force actuating device. In this manner, the computing device may control the actual force applied to a pressure sensing body part to a desired force which depends upon the positions of related joint body parts. In addition, the interface is comprised of a displacement actuating device which produces a displacement which is transmitted to a displacement applying device (e.g., a texture simulator). The displacement applying device applies the generated displacement to a pressure sensing body part. The force applying device and displacement applying device may be combined to simultaneously provide force and displacement information to a pressure sensing body part.

Abstract: A novel miscible blend of component polymers comprised of from about 5 weight percent to about 95 weight percent of a polybenzimidazole and from about 95 weight percent to about 5 weight percent of an aromatic polyamide aromatic polyamide-hydrazide or aromatic polyamide containing heterocyclic linkages. Miscibility of the component polymers of the blend is indicated by infrared, X-Ray and Differential Scanning Calorimetry analyses and scanning electron photomicrographs. In a film or molded article of a blend mostly comprised of a polybenzimidazole, it is preferred that the aromatic polyamide, aromatic polyamide-hydrazide or aromatic polyamide containing heterocyclic linkages be present in the blend in an amount sufficient to result in a blend with improved tensile properties compared to the polybenzimidazole and that is more thermally processable than the polybenzimidazole. In a blend mostly comprised of an aromatic polyamide, aromatic polyamide-hydrazide or aromatic polyamide containing heterocyclic linkages, it is preferred that the polybenzimidazole be present in the blend in an amount sufficient to result in a blend with increased thermal stability and nonflammability compared to the aromatic polyamide, aromatic polyamide-hydrazide or aromatic polyamide containing heterocyclic linkages. The blends, particularly in the form of films or molded articles, may be post-treated with heat or sulfonating agent in order to minizime their shrinkage when subsequently subjected to heat and in order to increase their resistance to solvrnts and acids.

Abstract: An invention providing a hard limiter (110) between the pulse width modulator (112) and output drive transistors (114) of a class-D amplifier is disclosed. The limiter (110) functions by controlling the duty cycle of the pulse width modulator output, which directly corresponds to the magnitude of the voltage appearing across the load output transducer. The pulse width modulated (PWM) signal is compared to the outputs of a pair of one-shot circuits (210) (single pulse generators). If either the positive pulse or the negative pulse of the PWM signal is shorter than the one-shot pulse, then the one-shot pulse is substituted for the PWM pulse. This sets the maximum and the minimum values for the duty cycle of the PWM signal, thereby limiting the positive and negative value of the corresponding output voltage. <IMAGE>
