Title: Improved brake actuator
Inventor: SPRAGUE GARY R
IPC: B60T17/08
Filed: 2001-08-23
Granted: 2009-08-18
Abstract: An improved diaphragm-type pneumatic brake actuator wherein thediaphragm (92 ) is releasably secured to the piston (102) as the diaphragm is inverted durin g actuation of the braking system of a vehicle thereby reducing wear of the flexible diaphragm (92) and improving the performance of the brake actuator. In the disclosed embodiment, a rib or lip (110) is formed on the surface of the diaphragm which receives the periphery of the piston as the diaphragm (9 2) is inverted forming a mechanical interlock between the diaphragm (92) and th e piston (102) thereby preventing spacing of the contact surface of the piston b(102) and the central portion of the diaphragm (92) and frictional wear between the peripheral edge of the piston and the diaphragm. In the preferre d embodiment, the piston includes an arcuate rim (108) which extends away from the central portion of the diaphragm (92) when the diaphragm is located in i ts extended cup-shaped position prior to actuation of the vehicle braking syste m and the diaphragm then conforms to the arcuate rim (108) as the diaphragm (9 2) is inverted and the diaphragm rib (110) snaps over the piston rim as the diaphragm (92) is inverted to actuate the vehicle braking system. The diaphragm rib (110) may be molded on the surface of the diaphragm when the diaphragm is molded without any substantial increase in cost.

Abstract: A delivery apparatus (10) includes a tubular sheath (12) including proximal, intermediate (20) , and distal (18) portions defining a lumen (16). A wall o f the distal portion is transparent, allowing observation of the lumen (16) within the distal portion.

A self-expanding stent (59) is disposed within the intermediate portion (20), and a bumper member (30) is slidably disposed within the lumen (16) proximat e the stent (50). Before use, the sheath (12) is retracted to bump the stent (50) forward into the distal portion (18) until the stent is observed within the distal portion. After the apparatus (10) has been pre-loaded, the distal portion is advanced into a blood vessel, e.g., across a stenosis, and the sheath (12) is retracted, causing the leaflets (24) to open and allow the stent (50) to be deployed, whereupon the stent (50) automatically expands to dilate the stenosis.

Abstract: An apparatus for testing stiffness characteristics of an article such as a piece of lumber moving in a conveying direction transverse to the testing axis, comprises a bearing unit capable of contacting the article at two spaced apart portions thereof. A first deflecting unit includes a first working element applying a first thrust against a loaded area on the article at an intermediary portion thereof located between the spaced apart portions, to produce an article deflection of a first magnitude. Each working element defines a loading surface extending substantially parallel to the article-conveying path. A second deflecting unit includes a second working element for applying a second thrust against a loaded area of the article intermediary portion, to produce an article deflection of a second magnitude. Load cells coupled to the bearing unit generates signals indicative of respective magnitudes of the thrusts, from which a computer derives stiffness indication.

Abstract: A telecommunications network comprising an SDH ring (9) of a plurality of interconnected MPLS (Multi Protocol Label Switching) enabled network devices (2) (SONET / SDH / WDM multiplexers) is configured to support both central and distributed network / routing protocols. Central management of the network is effected by a central management terminal (1) by means of OSI protocols run over a first data communications network (DCN) (5) of embedded Data Communications Channels (DCCS) (5), (5a). Distributed management of the network is performed by means of MPLS / IP protocols run over a second data communications network (DCN) (6) of embedded Data Communication Channels (DCCS) (6), (6a), (6b), (6c), (6d). The topologies of the two DCNs (5), (6) are different. The central management DCN (5) extends (link 5a) to the central management terminal (1) via an Ethernet interface, whereas the distributively managed DCN (6) is blocked at the interface. Data devices (3), in the form of MPLS enabled switches or routers, are connected to the SDH ring (9). The distributed control DCN (6) extends (links 6a, 6b, 6c, 6d) to the data devices (3a), (3b), (3c), (3d), whereas the centrally controlled DCN (5) is prevented from extending to the devices (3). Thus an existing legacy optical network may be converted so as to run two DCNs in parallel, the first DCN (5) supporting OSI protocols (in a centrally managed environment) and the second DCN (6) supporting GMPLS (Generalised MPLS) protocols that strictly follow data traffic.

Abstract: The present invention features a docking station for connecting a conventional wireline telephone or system of conventional telephones to one or more handheld wireless telephones, enabling a conventional wireline telephone to send calls to and receive calls from a wireless telephone network. This arrangement can eliminate the requirement for a separate wireline telephone service. The wireless telephone may be easily removed from the docking station for independent use as a mobile wireless telephone. The docking station is provided with a specially configured removable connecting sleeve which may be used to connect a particular make and model of handheld wireless telephone to the docking station. The docking station may comprise more than one connecting sleeve so that more than one handheld wireless telephone may be accessed by a wireline telephone connected to the docking station. Docking station circuitry simulates the familiar conventional wireline telephone environment so that a conventional wireline telephone may access the wireless network in the same manner that landline telephone network is accessed.

Granted: 2013-01-29
Abstract: L'invention concerne une méthode bon marché de production de peptides, y compris des peptides antimicrobiens (AMP), à partir de microbes. La méthode de l'invention permet d'améliorer considérablement les rendements des peptides/AMP, par comparaison avec les méthodes antérieures connues. La méthode de l'invention permet curieusement d'utiliser Pseudomonas fluorescens pour produire des AMP et d'autres peptides. Plusieurs éléments de l'invention peuvent être utilisés seuls ou en association. L'invention concerne la production de peptides/AMP dans des précurseurs concatémériques. Elle concerne également de nouvelles méthodes d'assemblage de monomères en multimères, et de clivage des multimères pour produire des monomères actifs. L'invention concerne aussi l'utilisation de ces multimères fondus avec des peptides de support pour produire des protéines hybrides. De préférence, tant les multimères que les protéines hybrides (multimères comportant les polypeptides de support) manquent d'équilibrage de charge. L'on a découvert, de manière surprenante, qu'il n'est pas nécessaire de décaler les charges positives de multiples copies d'AMP dans des constructions multimériques. Les méthodes de l'invention permettent ainsi d'utiliser une gamme plus étendue de multimères et de peptides de support.
