Abstract: There is provided a flat bed trailer including a hinged ramp tail which can be raised between a lower loading and an upper transport position. The ramp tail is raised and lowered by a linkage and extensible lifting means acting on the linkage. The advantange of the linkage of the present invention is that the extensbile liftming means - hydraulic cylinders - are retracted when the ramp is in its raised position, rather than being extended. In addition the linkage provides for an over-center lock further strengthening the ramp tail in its raised position, thus significantly lessening the amount of strain placed on the hydraulic cylinders and other mechanics as compared to that in the prior art.

Title: Spectrometre de masse pour macromolecules dote de detecteurs de particules cryogeniques
Inventor: TWERENBOLD DAMIAN
IPC: G01N33/50
Filed: 1995-07-31
Granted: 2001-10-16
Abstract: Un spectromètre de masse comportant un détecteur de particules cryogénique sensible aux phonons (1) permet de déterminer les masses de macromolécules dont les protéines, les grands peptides, les longs fragments d'ADN et les polymères. L'énergie cinétique de la macromolécule chargée (6) soumise à accélération par effet électrostatique est absorbée dans le détecteur de particules cryogénique (1), ce qui excite les phonons (7) qui sont détectés par les capteurs de phonons (2). La détection des macromolécules se fait en mode de comptage des particules séparées avec une sensibilité indépendante de leurs masses respectives. Dans un mode de réalisation, le spectromètre de masse contient un détecteur de particules mono-canal cryogénique conférant une sensibilité élevée. Dans un autre mode de réalisation, le spectromètre de masse comporte un ensemble de détecteurs multi-canal cryogéniques à résolution spatiale, conférant à la fois une sensibilité élevée et un débit important. Dans ce mode de réalisation, ledit spectromètre de masse se compose d'une enceinte à vide dans laquelle se trouvent un aimant (48), un séparateur de masses (50), une chambre de pré-accélération (51), et un ensemble de détecteurs cryogéniques (53) sensibles aux phonons. Ledit ensemble de détecteurs cryogéniques (53) est constituée d'un absorbeur (42) et d'un nombre déterminé de capteurs de phonons. Le séparateur de masses (50) est placé dans le champ magnétique de l'aimant (48) et relié, ainsi que la chambre de pré-accélération (51), au potentiel électrique U1, tout en étant électriquement isolé de l'aimant. L'ensemble de détecteurs cryogéniques est relié au potentiel U2 de la masse. Les macromolécules sont accélérées par la différence de tension U1-U2 et atteignent l'ensemble de détecteurs cryogéniques (53) avec une énergie cinétique proportionnelle à U1-U2. Ledit ensemble de détecteurs cryogéniques (53) est refroidi à la température de service T2 grâce au plongeur réfrigérant (54) du cryostat (58) caractérisé par une température de bain T2 sur lequel il est monté. Ledit ensemble de détecteurs cryogéniques 53 est protégé contre le champ magnétique de l'aimant (48) par un blindage anti-magnétique (52). La masse de la macromolécule est déterminée à partir des informations spatio-temporelles fournies par ledit ensemble de détecteurs cryogéniques (53).

Title: Determination of characteristics of material
Inventor: MENDER CLAS FREDRIK
IPC: B07C5/344
Filed: 1995-08-21
Granted: 2003-02-25
Abstract: A system for automatically inspecting matter for varying composition comprises one or more detection stations (131) through which one or more streams of matter are advanced and particular materials therein are detected through their diffusely reflected IR spectra, if any, and/or through their variation of an electromagnetic field by their metallic portions, if any. A row of light sources (105) distributed across the overall width of one or more belt conveyors (104) may cause desired portions (125) of the stream to reflect light diffusely onto a part-toroidal mirror (107) extending over that overall width, whence the light is reflected, by a rotating, polygonal mirror (108) through optical filters dedicated to differing IR wavelengths, onto detectors (120) the data output of which is utilised in controlling solenoid valves operating air jet nozzles (116) which separate-out the desired portions.  Alternatively or additionally, an oscillator (137) and an antenna (138) which extends over that overall width generate an electromagnetic field through the belt (104) and sensing coils (139) sense variations therein produced by metallic portions of the stream passing through the detection station (131) and the detection data produced by the sensing coils (139) is used to control the solenoid valves operating the nozzles (116) to separate-out the metallic portions.

Abstract: An adjustment mechanism for a car seat provides multiple vertical locking positions for adjusting the attitude of a seat with respect to an automobile seat cushion and back. The car seat has a base with forward and rear support walls each having a key way matching the profile of the stem portion of a locking plunger. The plunger has a forward handle portion and a pair of shoulder portions extending to the rear of the plunger which engage mating recesses in a key way formed in an adjustable support member. The adjustable support member is slidably arranged between the forward and rear support walls of the base. The plunger is spring biased by a spring mounted in a spring aperture formed in the rear of the plunger stem. The relative positions of the support member and the car seat base are adjusted by withdrawing the plunger until the shoulder portions clear the support member key way, adjusting the position of the support member with respect to the car seat base and releasing the plunger to enable the spring to force the plunger rearwardly into the support member key way.

Title: Method of enhanced max-log-a posteriori probability processing
Inventor: CROZIER STEWART
IPC: H03M13/29
Filed: 1998-08-14
Granted: 2011-06-28
Abstract: The invention comprises an enhancement to max-log-APP processing that significantly reduces performance degradation associated with introducing the "max"  approximation into log-APP computations, while still maintaining lower computational complexity associated with max-log-APP processing. This enhancement is achieved by adjusting extrinsic information produced by a max-log-APP process where the magnitude of the extrinsic information is reduced, for example, by multiplying it with a scale factor between 0 and 1. An embodiment of the invention further provides an efficient method of storing the extrinsic information.

Abstract: The invention provides a method of synthesizing oligonucleotide N3'.fwdarw.P5' phosphoramidates using an amine-exchange reaction of phosphoramidites in which a deprotected 3'-amino group of a solid phase supported oligonucleotide chain is exchanged for the amino portion of a 5'-phosphoramidite of an incoming monomer which has a protected 3'-amino group. The resulting internucleotide phosphoramidite linkage is then oxidized to form a stable protected phosphoramidate linkage.  The method of the invention greatly improves product yields and reduces reagent usage over currently available methods for synthesizing the above class of compound.

Granted: 2002-01-22
Abstract: A low insertion force, high current electrical connector assembly that is capable of transmitting a wide range of current levels, particularly high levels of current such as that found in a power distribution center, is provided. The connector assembly includes a cylindrical housing having an open end to receive a pin. A contact cage having a number of flexible beams is positioned concentrically within the housing to surround and contact the pin.  The beams are provided in sets or banks which are offset from each other by zig-zag bridge members. The zig-zag bridge members ease the process of rolling the cage into a generally cylindrical shape for insertion into the housing and provide a compact design to reduce material consumption. The housing includes a reduced diameter section which acts as an overstress protector for the contact cage by minimizing movement of the pin within the housing and as a positive stop for the contact cage once it is assembled within the housing. The housing may also include an annular recess in the exterior wall which serves as a keying feature for connection of the housing to another component, such as a bus bar.
