Abstract: The present invention involves perfluoro compound emulsions including nitric oxide, their preparation and their use. These emulsions provide a new source of nitric oxide. Such nitric oxide-containing emulsions may be used for the administration of nitric oxide to individuals in need thereof. Individuals in need of nitric oxide administration can include those suffering from hypertension, preeclampsia and a number of other situations where an increased blood flow, for example, is desirable. In addition, given the long use of perfluoro compound emulsions as blood substitutes, the present invention provides a relatively safe mode for administering and distributing nitric oxide-without potential negative side effects such as toxicities due to drug metabolites.

Abstract: A process for the production of S(+)-ibuprofen-particles having improved flow properties comprises the steps that coarse-crystalline S(+)-ibuprofen is molten and then in a molten condition is finely distributed in a non-solving medium, preferably in cold water, and is chilled therein. This chilling results in a fine-crystalline primary structure that agglomerates to a secondary structure. In this agglomerate form the product is obtained which is filtered out and is dried. Such particles are suitable for direct pressing of tablets, optionally, tableting auxiliary substances being added, also for the production of tablets having a retarded release of the active substance.

The rocker (14) extends transversely to the shaft (7) and its ends are designed to be able to interact with respective pistons (17, 18) of the rams (12, 13), each ram comprises three pistons (24, 25, 17; 26, 27, 18) which are coaxial and have different cross sections, arranged in chambers (28, 29) of corresponding cross sections formed in the body (11). This electrohydraulic actuator permits extremely quick and easy control of gear selection for a structure which is relatively simple and has a modest cost of manufacture.

Abstract: Keyboard constructions and methods are described which force or provide feedback for finger action that will enhance stability of the carpal tunnel tendons. Methods are described for reducing incidence of carpal tunnel syndrome in a person who operates a keyboard, involving monitoring actuation of switches, measuring a depression characteristic, comparing the depression characteristic with a predetermined value, and creating a signal corresponding to the number of keystrokes executed with a depression characteristic less than the predetermined value. A method is also described for detecting unphysiologic tendon translation denoting tendon instability in the carpal tunnel of a person who engages in repetitive hand motion.

Abstract: An intelligent network telecommunications service allows a calling party (22) to provide a voice message which is converted by the service to a text message. The text message is delivered to any of a plurality of types of media formatters (90), which in turn transmit the text message to corresponding types of receiving equipment (100). The text messages can be delivered to a sole called party or to a distribution list of called parties.

Abstract: A new and useful a plastic article, particularly plastic siding, with an accent color pattern incorporated therein, a specially formed accent color pellet which is useful in manufacturing such an article, and a process for producing the article using the pellets are provided. The process contemplates extruding a plastic product from a base material formed of powder-sized particles and specially formed accent color pellets. The accent color pellets are alloyed masses of resins and pigment which are larger than the powder particles of the base material, and have a higher vicat softening point temperature than the base material. The alloyed pellets are designed to melt controllably and to mix controllably with the base material.

Abstract: With the objective of simplifying the splicing of optical fibres and obtaining a very high degree of accuracy in the positional setting of the fibre ends prior to splicing the ends together fully automatically, the relative positions of the fibre ends are determined with the aid of laser light diffraction. By illuminating the fibre ends (1, 2) with laser light (3) and studying the image of the diffraction pattern on a display screen (6), which pattern can be related directly to the perpendicular distance between the fibre ends and the relative offset between the geometric axes of the ends, it is possible to determine the distance between the fibre ends by direct image analysis. A suitable splicing distance between the gap between the fibre ends can then be adjusted automatically to a value suitable for splicing, with regard to fibre material and fibre dimensions.
