Abstract: An autosampler (10) include at least one specimen container tray (16), havin g a plurality of recesses (30) for receiving a specimen container (20), is removably fixed to a ground plate (15). A specimen container manipulating device (32) is positioned on top of the ground plate (15) and adjacent to the specimen container tray (16). The specimen container manipulating device (32) comprises a gripper comprising a gripper housing (34) and a plurality of gripping fingers (40, 4 2, 44). The gripping fingers (40, 42, 44) are held in place by a member (36) which is movable inside the gripper housing (34) between an uppe r and lower position. Shape memory metal (54) is positioned inside the gripper housing (34) and connected to the movable member (36) for controlling movement of the gripping fingers (40, 42, 44). When heat is applied to the shape memory metal (54), the shape memory metal (54) constricts, it moves the movable member (36) from the lower position to the upper position, causing the gripping fingers (40, 42, 44) to move from the closed position to the open position.

Title: Liquid cooling of glassware molds
Inventor: FLYNN ROBIN L
IPC: C03B9/353
Filed: 2001-02-22
Granted: 2006-10-03
Abstract: A system and method of cooling glassware molds by directing liquid coolant to the blank or blow mold halves of a glassware forming machine through an enclosed pivotal rotary union-type structure. A coolant manifold is carried by each pivotal mold arm, and communicates with coolant inlet and outlet ports at the lower end of each mold part. The manifold is connected by a floating shaft seal and a rotary union assembly and a crank arm to a coolant source and coolant return in the section box of the associated machine section. Each pivotal connection - i.e., between the section box and the crank arm, between the crank arm and the rotary union assembly, and between the rotary union assembly and the floating shaft seal comprises a bi-directional rotary union for feeding liquid coolant to the manifold and mold parts, and returning coolant from the manifold and mold parts. Dynamic floating seals between the coolant manifold and the mold parts, and between the coolant manifold and the rotary union mechanism, accommodate relative motion between these components as the mold parts are opened and closed.

Granted: 2007-12-18
Abstract: L'invention concerne un clapet à bille (10) possédant un mécanisme de retenue qui, quand il est soumis à un déplacement très léger, permet à une bille (20) de se séparer du siège de clapet (48) pendant la rotation, mais reste en contact avec le siège de clapet (48), de manière à empêcher l'introduction de débris entre la bille et le siège de clapet et à se replacer instantanément sur le siège de clapet dans le cas d'une fermeture. Ce changement instantané et automatique du trajet de positionnement sur le siège de clapet sous l'effet d'une réaction au moment de la fermeture permet d'obtenir une étanchéité efficace contre des liquides agressifs sous pression élevée, ce qui empêche la fuite de ces liquides au-delà des éléments du clapet, tout en permettant simultanément au clapet d'effectuer une rotation sans que celle-ci soit absolument assurée. Ceci apporte une solution à la contradiction entre les trajets de charge à travers le clapet, notamment à travers le croisillon pendant la rotation et à travers le siège de clapet pendant la période d'étanchéité.

Abstract: La présente invention concerne un ensemble oscillant destiné à faire pivoter une matrice de découpage construite et agencée pour découper des ébauches de matériau en tôle. L'ensemble oscillant comprend une structure de support de matrice pivotant autour d'un axe de pivotement. La structure de support de la matrice reçoit et porte la matrice de manière que le matériau en tôle puisse être acheminé dans la matrice dans un sens d'acheminement et de manière que le pivotement de la structure de support de la matrice fasse pivoter la matrice par rapport au matériau en tôle. Un ensemble d'entraînement rotatif réversible fait tourner un arbre de sortie rotatif dans un premier et un second sens de rotation opposés. Une unité d'entraînement mobile linéairement de la matrice est reliée fonctionnellement à l'arbre de sortie de manière que (a) la rotation de l'arbre dans son premier sens de rotation déplace l'unité d'entraînement de la matrice, d'une manière générale linéairement, dans un premier sens d'entraînement de la matrice, et (b) la rotation de l'arbre dans son second sens de rotation déplace l'unité d'entraînement de la matrice, d'une manière générale linéairement, dans un second sens d'entraînement de la matrice opposé au premier sens. L'unité d'entraînement de la matrice est reliée fonctionnellement à la structure de support de la matrice de manière que (a) le mouvement de l'unité d'entraînement de la matrice dans son premier sens d'entraînement, tel que ci-dessus, fait pivoter la structure de support de la matrice dans une première position de découpage dans laquelle la matrice de découpage peut découper une première ébauche dans le matériau en tôle acheminé dans celle-ci et (b) après découpage de la première ébauche et avance du matériau en tôle par rapport à la matrice dans le sens d'alimentation, le mouvement de l'unité d'entraînement de la matrice dans son second sens d'entraînement, tel que précité, fait pivoter la structure de support de la matrice dans une seconde position de découpage dans laquelle la matrice de découpage peut découper une seconde ébauche dans le matériau en tôle.

Title: Method and system for facilitating telecommunications service provisioning and service assurance
Inventor: DOHERTY ALAN G
IPC: H04L12/26
Filed: 2001-06-05
Granted: 2006-05-30
Abstract: An automated system coordinates, controls and polices installation of customer premise equipment (CPE) for telecommunications services and provides continuing service assurance. The system verifies equipment availability on service request, schedules a qualified technician to install the CPE, and assigns distribution equipment resources to the CPE. The system notifies the technician of the installation date. The equipment resources are auto-assigned to the CPE to facilitate installation procedures. The system also auto-detects installation of the CPE and auto-enables service when the CPE is installed. Customer record creation and maintenance is automatic, and installation or operation of unauthorized equipment is inhibited. Post-installation monitoring and automatic scheduling of repair for system or equipment faults ensures continuing service assurance. The advantage is reduced service delivery time, reduced operations costs and increased customer satisfaction.
