Title: Optical measurement system for detecting luminescence or fluorescence signals
Inventor: PAFFHAUSEN WOLFGANG
IPC: G01N21/17
Filed: 1998-10-09
Granted: 2007-05-29
Abstract: In the measurement system for detecting optical signals of microassays, the signal- generating test objects 5 are arranged on an investigation surface of a planar carrier 4. The planar carrier 4 is, in particular, a microtitre plate for biological objects. In principle, the measurement system comprises an optical imaging arrangement which reduces the size of the test objects 4 to be measured in such a way that all the objects are imaged completely on a two-dimensional, photosensitive image sensor 6. For imaging, a high-resolution glass-fibre taper element 1 having a large-area 2 and a small-area end 3 is used in this case, whose end surfaces 2, 3 are selected such that the large-area end surface 2 corresponds at least to the investigation surface of the carrier 4 and the small-area end surface 3 corresponds to the size of the image sensor 6, the ratio of the end surfaces 2, 3 producing the scale of reduction of the optical imaging arrangement in order to image the investigation surface of the carrier 4 completely onto the image sensor 6.

Granted: 2006-10-24
Abstract: Apparatus for separating solvent in a feed of solvent and deasphalted oil produced in a deasphalting process includes a feed line (1) for receiving the feed and constructed and arranged to produce a stream (10) of fluid containing supercritical solvent and deasphalted oil. A substantially horizontally disposed inlet line (10A) receives the stream of fluid and is designed to effect two phase laminar flow at the outlet (51) of the inlet line (10A). The two phase laminar flow has a substantially horizontally disposed interface (51A) that divides the stream into an upper part (55) containing the lighter supercritical solvent which floats on a lower part (56) containing the heavier deasphalted oil.

Abstract: A wear-resistant hardfacing and a method for applying such a hardfacing is taught herein. A finely powdered, wear-resistant alloy and a polyvinyl alcohol (PVA) solution slurry is coated onto the metal surfa ce of a tool, implement, or similar item to be hardfaced. Alternatively, a binding coating of PVA solution may be applied to the metal surface followed by application of a layer of a powdered alloy. After the slurry or PVA binding coating has dried, leaving a dry coat of alloy in a PVA matrix, the metal surface is heated to the fusion temperature of the alloy in vacuum, in an inert gas atmosphere, or in hydrogen atmosphere. The metal item with the fused coating is heat treated to impart desired mechanical properties to the part substrat e material. The method of the present invention gives a smooth, dense coating of the wear-resistant hardfacing without nonmetallic inclusion s.

Title: Control of microsporogenesis by externally inducible promoter sequences
Inventor: HOWARD JOHN
IPC: C12N15/82
Filed: 1991-05-13
Granted: 2003-02-04
Abstract: An inducible promoter is used to regulate expression of a gene which is known to be critical in microsporogenesis, i.e., the production of pollen. The selected gene's control sequences are modified so that it is normally "off" and as a result the plants are male sterile. When it is desired to reproduce the male sterile plants, male fertility is restored by treating the plants with a non-phytotoxic chemical which induces expression of the critical gene.

Abstract: La présente invention, composée d'un système (10) et d'un procédé permettant de déceler le débranchement et l'occlusion de la tubulure (16) d'un respirateur (12) côté malade, décèle le débranchement de la tubulure (16), ouvre la valve d'exhalation, distribue un flux inerte de mélange respiratoire dans la tubulure (16), met hors service l'enclenchement respiratoire, et enclenche une alarme. La présente invention permet également de déceler un rebranchement de la tubulure (16) afin d'amorcer la reprise de l'assistance inspiration. Pour la détection des occlusions, des capteurs de pression (26,36) dans les branches inspiratoires et expiratoires (20,18) de la tubulure (16) déterminent les chutes de pression dans la tubulure (16). Le système compare les deux valeurs de chute de pression et dès que l'occlusion a été détectée, il enclenche une alarme et le respirateur (12) réagit en conséquence afin de protéger le patient (14) de la surdilatation pulmonaire. Le système permet également de surveiller la diminution de l'occlusion dans un mode de contrôle cyclique de l'état d'occlusion basé la pression, le respirateur (12) pouvant reprendre la ventilation normale lorsque le système ne détecte ni une occlusion de circuit ni une occlusion de l'orifice expiratoire.

A second and a third coolant discharge pipeline (11, 12) extend from the reversible distributor (10) so that selectively all of the coolant can flow through the second coolant discharge pipeline (11) to the tools (5) or all of the coolant can flow through the third coolant discharge pipeline (12) to the coolant supply source or a part of the coolant can flow through each of the second and third coolant discharge pipelines. To operate the equipment if coolant flows throu gh the cooling device (8), a flow monitor (14) detects the movement of coolant and sends an electronic signal to the electronic component (19). The power is supplied from an external power source to the driving motor (1) only when the flow monitor (14) signals that coolant is flowing.

Abstract: A single wheel caster apparatus is disclosed for supporting a plow. The apparatus includes a wheel and an axle, the axle extending through the wheel such that the wheel is rotatably supported by the axle. Additionally, a first and a second fork are provided with each fork having a proximal and a distal end. A head which defines a plurality of detents is rigidly secured to a cross member and extends therefrom in a direction away from the wheel. A tube has a first and second extremity and defines a bore for the reception therein of the head. The tube defines a first radial passageway which is disposed in the vicinity of the detents. A flexible tubular lining is disposed within the bore of the tube. A first member is slidably disposed within the first passageway with the first member being disposed adjacent to the lining such that the lining is located between the first member and one of the detents. Also, a first spring is disposed within the first passageway for biasing the first member towards the one of the detents, the arrangement being such that an interaction of the first member with the lining permits controlled relative rotation of the head within the tube so that when the wheel rotates about the axle, wobble of the wheel and the forks is inhibited, while the interaction permits rotation of the forks relative to the tube during turning and reversing of the plow.

Title: Automated document cashing system
Inventor: GUSTIN ROBIN HALEY
IPC: G07F19/00
Filed: 1999-07-08
Granted: 2012-09-18
Abstract: An automated document cashing system is provided with an automated machine that cashes monetary transaction documents such as checks, money orders, and that makes deposit entries into the bank account of the user after validation of the user and monetary transaction document, without the aid of a bank teller. Validation of the identity of the user is performed with the use of a card associated with intelligence that identifies the user. A biometric device also may be used in identifying the validity of the user. Validation of the document involves one or more of: validating the presence of a signature; validating the amount of the monetary transaction document including a manual entry of the amount by the user; validating CAR against the LAR; and validating the banking system parameters and rules for the customer and/or the transaction. To assist in the automatic analysis of the data on monetary transactional documents or on remittance documents, the user is prompted to provide a bounding box about the data. An image touch screen may be touched by the user to locate the bounding box and the user may magnify the data to fill the boundary box to exclude other data from this analysis. After document and person validation, the system will dispense money or transfer monies to a savings account, a checking account, a smart card, or the like. The system will also write money orders or wire transfer money. By supplying monies in the form of cash, credit car authorization, smart card balance, or the like to the machine, the user can pay bills such as a utility bill through the system or purchase items dispensed by the system.
