Title: Method of establishing at least one enveloped flow in a channel
Inventor: LARSEN ULRIK DARLING
IPC: G01N15/14
Filed: 2001-03-09
Abstract: With a method of establishing an enveloped flow in a channel, in the channel an envelopment area ( 3 ) with a channel section ( 6, 7 ) is configured to which a stub with an outlet is connected, where the stub, which can be configured as a polyhedron, is arranged substantially at right-angles to the envelopment area and with the plane of the outlet substantially at right-angles to the channel section. An inlet channel ( 9, 11 ) and an outlet channel ( 8, 10 ) are connected to the envelopment area. By providing a narrowing-down in the cross-section of the channel in immediate extension of the envelopment area ( 3 ), a hydrodynamic focussing of the sample fluid is achieved when a fluid, such as a sample fluid, is introduced into the stub, and a carrier fluid is introduced into the inlet channel. The advantage of the invention is that since it is necessary only to have two fluid inlets, a relatively simple structure can be established, which can be built up in a monolithic manner, e.g. by injection molding.

Abstract: Un corps de véhicule ou un conteneur frigorifique (10) possède une unité de réfrigération (15) avec un boîtier (16) formant une paroi terminale du corps ou du conteneur (10). L'unité (15) possède un châssis périphérique (14) faisant partie intégrante de la structure du corps ou du conteneur (10). Une ventilation (25) reçoit de l'air chaud provenant de l'espace de chargement (26) du corps ou du conteneur et un ventilateur ou une soufflerie (27a) dirige l'air sur un échangeur thermique (30) dont les mailles ou les fils métalliques sont enduits d'eau froide pulvérisée sur les bobines d'un évaporateur (29) par des barres de pulvérisation (28).

Abstract: Dans un circuit de condensateur à commutation avec multiplexage temporel, certains condensateurs sont partagés pendant des périodes de temps local d'une période de temps global, pour permettre une réduction de la capacitance totale du circuit. On peut obtenir des économies correspondantes dans la superficie occupée par les puces dans l'implantation d'un circuit intégré et des économies de composants dans une implantation non intégrée. La présente invention s'applique en particulier à un circuit avec multiplexage comprenant un réseau de condensateurs constitué par des premier et second condensateurs communs et par des premier et second groupes de plusieurs condensateurs. Les condensateurs peuvent par commutation être inclus dans le circuit avec multiplexage et exclus de celui-ci pendant différentes périodes de temps local. Le premier condensateur commun peut par commutation être inclus dans le circuit, lorsque n'importe lequel des condensateurs du premier groupe participe au fonctionnement du circuit avec multiplexage, réduisant ainsi la grandeur de ce condensateur appartenant au premier groupe de condensateurs. De même, les premier et second condensateurs communs peuvent par commutation être inclus dans le circuit, lorsque n'importe lequel des condensateurs du second groupe participe au fonctionnement du circuit multiplexé.

Title: Photometric cell for assessment the intensity of colouring of reactive tape
Inventor: VOLF RADKO
IPC: G01J1/58
Filed: 1987-06-02
Abstract: The photometric cell is applied for medical purposes, in the analytical labs and the chemical industry. The reactive tape - to be subject to assessment - is lightened under a predefined angled from a working luminescent diode, while the reflected light - reduced from the coloured absorbing surface of the tape - is calculated through photoresistance, under which the own mirror reflection - derived from the protective diaphragm reactive tape - is eliminated in a certain way through the located absorption chamber. The useful signal - shot by the photoresistance and a suitable electronic device - is compared against the light flow of the support luminescent diode.

Title: Windtrap for power development
Inventor: WHELAN MATTHEW P
IPC: F03D3/06
Filed: 1990-01-03
Abstract: ABSTRACT            The several methods used to develop windpower have the disadvantage of losing most of the wind's force in their operation, example, where vanes are used slippage is a big problem, and in the vertical mast type of machines such as the "Darrieus" and "Savonius" a lot of power is lost by resistance on the return side of the mast.  This invention, the "Windtrap", holds all the wind within the dimensional area of each unit when on the drive or power side, and is so designed that each part comes edge on to the wind on the return side of the mast giving minimum resistance.

Abstract: A laser gas used in a rare gas fluoride excimer laser is efficiently refined with little loss of the principal rare gas such as Ar, Kr or Xe by sequential contact of the laser gas first with a reactive metal, e.g. Si or Fe, for conversion of the fluorine source gas such as F2 or NF3 to a metal fluoride, then with a solid alkaline compound, e.g. Ca(OH)2, for conversion of gaseous fluorides to solid metal fluorides, next with zeolite which is adsorbent of most of the remaining impurities and finally with an alkaline metal, e.g. Ca or Na, for decomposition of CF4 to form a solid metal fluoride and carbon.  CF4 is formed during operation of the excimer laser by reaction of fluorine with a fluororesin used as electrical insulator in the laser apparatus, and accumulation of CF4 in the laser gas causes significal lowering of the laser output power.

Title: Automatic quilting machine for specialized quilting of patterns which can be created by utilizing computer graphics in conjunction with a reprogrammable computer
Inventor: BROWER DAVID
IPC: D05B21/00
Filed: 1990-03-30
Abstract: ABSTRACT                An automatic quilting machine for use in stitching individual selected patterns into a large fabric such as a bedspread or quilt. The bedspread or quilt is stretched on a large metal frame which is mounted on a table which can be moved in the X-direction, the Y-direction, or any X-Y          combination direction. The sewing machine head is mounted on a cross beam which is aligned at the approximate center point of the metal frame on which the fabric is stretched. The needle of the sewing machine head can stitch a pattern into any location in the fabric and the metal frame is moved in any direction relative to the fixed sewing machine head in order to bring the desired stitch location on the fabric into alignment with the sewing machine head. The pattern can be created through reading by a scanner when then converts the pattern into machine readable language which is stored in a process controller. Alternatively, the pattern can be hand drawn on a monitor by graphic systems such as a mouse combined with computer aided design programs which provide graphic menus and through which the drawn pattern can be converted into machine readable language which is then stored in the memory of a process controller. The stored pattern can be subsequently stitched into the fabric through commands from the process controller which direct a remote control apparatus to move the table in the desired direction to create the pattern.

Abstract: ABSTRACT    An interflap segmented seal is provided for use between adjacent flaps of an axisymmetric vectorable exhaust nozzle in order to minimize flow loss therebetween when the flaps are pivoted through different angles in order to turn the exhaust flow and vector the thrust. The overlapping seal segments are mounted to a backbone having an elliptical cross-section by a flange with a lobed hole in it through which the backbone passes.  Spacers between the flanges axially position the individual segments from each other.  Variable movement between adjacent flaps produces different angles between the sealing edges of the flaps which are often skewed with respect to each other and the flexibility afforded by the seals of the present invention allows the seals to minimize the leakage between the flaps and the seals.
