Abstract: Particles (10) are conveyed in a stream in a direction transverse to the width of the stream. Windows (14) view individual width zones of the stream and optical fibres (19) are associated with the windows to convey light passing through a window to a light detector (21). The windows (14) are rapidly opened and closed and a processor (32) is provided to determine which window (14) passed light detected by the detector (21) and accordingly which width zone of the stream the light emanated from. The windows (14) preferably incorporate liquid crystal shutters (24) which can be switched rapidly between light-transmitting and opaque states corresponding to open and closed states of the windows (14).

Abstract: The invention relates to an apparatus for separating and recovering solid particles transported by a gaseous flow. The apparatus includes a separation chamber (40), an admission conduit (43) by which the gaseous flow laden with particles arrives, an escape conduit (44) by which the flow leaves after having been relieved of its particles, a discharge conduit (47) toward which the particles separated from the gaseous flow are urged, a movable flap (49) making it possible with the discharge conduit to comprise a particle recovery box, and a helical device (52) placed in the discharge conduit to prevent the particles thus recovered from being re-aspirated by the rising flow that escapes via the escape conduit (44). The invention is applicable to magnetographic printing machines.

Abstract: The present invention relates to a novel inhibitor of histamine release, designed HRIF which is believed to represent a promising therapeutic agent for treatment of basophil and mast cell dependent disorders, including allergic diseases. This inhibitor is a human cytokine that antagonizes a human histamine releasing cytokine(s) designated HRF. HRIF has a molecular weight of about 8,000 to 10,000 daltons as determined by gel exclusion chromatography and has also been purified by ion exchange chromatography. HRIF is stable when heated at 60 DEG C for one hour, when frozen and thawed four times, and when treated with neuraminidase. Treatment with trypsin or chymotrypsin substantially destroys the activity of HRIF. The present invention includes compositions comprising substantially purified HRIF as well as methods for HRIF production and use. The invention also includes HRIF-producing cell lines and methods for producing such cell lines.

Abstract: For use in ophthalmic surgery, the surgeon has available a supply of "spare parts" which are artificial members, possibly simulating different components of the eye, that are suited, depending on their structural forms and shapes, for surgical implantation in the eye as and/or in connection with repair and/or reinforcement and/or replacement structures for damaged or diseased eye components. The members basically are made of cohesive sheet materials of biocompatible substances such as cross-linked hyaluronic acid, PMMA, or other equivalents thereof. Certain of such "spare parts" are particularly well suited for dealing with the problem of the torn posterior capsule when encountered during an extracapsular cataract extraction.

Abstract: A centrifugal pump for left ventricle assist includes a pump housing forming an impeller chamber with inlet and outlet passages and enclosing an impeller rotatable to move blood through the impeller chamber, and a rotor chamber enclosing a rotor integral with the impeller and rotatable to drive the impeller. An elastically deformable seal member separates the rotor and impeller chambers, and includes an annular lip seal surrounding a shaft which joins the impeller and rotor. A saline solution is supplied at a constant fluid flow rate to the rotor chamber through an inlet passage, and leaves the rotor chamber by perfusing into the impeller chamber along the interface between the shaft and lip seal. The saline solution thus provides hydrodynamic bearings between the rotating shaft and rotor, and the fixed pump housing and lip seal, and further prevents blood in the impeller chamber from entering the rotor chamber. The lip seal is configured to encourage flow of saline solution along the lip seal/impeller shaft interface, while resisting the flow of blood along the interface.

Abstract: In the case of a rotary swather the machine is connected to a carrying frame (3) so as to be capable of swivelling about a vertical axis (12) and a horizontal axis (9). In addition the machine in the retracted transport position is supported by a telescopic linkage (17, 18) against the carrying frame (3). In order to prevent lifting of the wheels when descending an incline or when pushing backwards and to suppress lateral drifting of the machine when running across an incline, preloaded helical compression springs (29) are built into the telescopic linkage (17, 18), which springs keep the machine in its normal position or return it to this.   So that no undamped vibrations can occur when turning and reversing the machine, friction brakes are incorporated into the telescopic linkage (17, 18) in the form of spring-loaded bushings (27), which brake in one direction but in the other direction have almost no braking effect. <IMAGE>

Abstract: A locking cap for anchoring an implanted medical device within a bone (such as an intramedullary fixation rod) has a cylindrical, helically threaded body, a socket concentrically disposed in one end, and an interface for cooperating with a driving tool, such as a wrench or screwdriver. Once a device such as an intramedullary fixation rod has been implanted within a bone, the locking cap is implanted by being threaded into the bone with a driving tool, its socket engaging the near end of the device. The socket of the locking cap can be smooth, or it can be threaded so as to thread onto the near end of the device as the cap is threaded into the bone. If threaded, the pitch of the cap's outer threads can exceed the pitch of the inner threads so that the cap advances into the bone more quickly than it advances onto the end of the device. Alternatively, the inner thread pitch can exceed, or equal, the outer thread pitch so that the cap advances into the bone more slowly than, or at the same rate as, it advances onto the end of the device, respectively.

Abstract: It has been discovered that it is possible to target any RNA molecule for cleavage by RNase P by forming a hybrid region consisting of a short sequence of base pairs followed by a terminal 3'- NCCA sequence. In the preferred embodiment, the region is formed by addition of an external guide sequence consisting of a nucleotide sequence complementary to the targeted site which includes a 3'-NCCA, wherein the sequence hybridizes to the targeted RNA to form a short sequence of double-stranded RNA under conditions promoting cleavage of the substrate at the nucleotide at the 5' side of the base-paired region by the RNase P or catalytically active equivalent thereof. Specificity is determined by the complementary sequence. The sequence is preferably ten to fifteen nucleotides in length and may contain non-complementary nucleotides to the extent this does not interfere with formation of several base pairs followed by a NCCA at the 3' end. These embodiments are particularly useful in the treatment of viral diseases and disorders associated with expression of specific proteins from mRNA.
