Granted: 2005-03-29
Abstract: An elastomeric electroluminescent (EL) lamp is provided wherein an electroluminescent system, advantageously monolithic, is provided in an elastomeric structure. As a result the lamp is thin, pliable and membrane like. A first envelope layer (104) is applied advantageously by screen printing to transfer release paper (102). An EL  system (108) is then applied, again advantageously by screen printing to the first envelope layer (104), and then a second envelope layer (114) is applied to seal the EL system (108) within the envelope. Appropriate windows (108) are cut or left open to allow electrical contact with the EL system. An optional adhesive layer (116) then may be applied if the lamp is to be used in transfer form for later affixation to a substrate. Alternatively, the lamp may be used as a self-contained elastomeric component installed in another product.

Abstract: A method of making a heater element has the steps of inserting into a smooth tubular casing a heating wire, filling a space between the wire and the casing with a compressible insulating mass, and closing ends of the space to confine the mass in the casing. Then the casing is radially inwardly compressed to form therein a successive of radially outwardly open annular grooves extending circumferentially fully around the casing and thereby radially compressing the insulating mass. The casing is formed with a succession of such grooves, which can be of V-shape and which are each endless so that the casing is corrugated.  Alternately the grooves are interconnected helically. Either way in accordance with the invention the grooves form axially relatively long and radially relatively thick outer rings and axially relatively short and radially relatively thin inner rings.

Title: Spectrometrie de masse a guide d'ions multipolaire
Inventor: GULCICEK EROL E
IPC: H01J49/04
Filed: 1999-01-22
Granted: 2006-07-11
Abstract: L'invention se rapporte à des guides d'ions multipolaires (6) conçus avec un ou plusieurs segments (1, 2, 3, 4) et positionnés dans une région (72) de vide poussé, qui fonctionnent en modes de sélection masse/charge et de fragmentation d'ions. Ces guides d'ions multipolaires individuels sont montés dans un ensemble linéaire ne comportant pas d'électrode entre chaque paire de guides d'ions multipolaires. Au moins une partie de chaque guide d'ions multipolaire monté dans un ensemble linéaire réside dans une région de vide à pression de fond élevée. Au moins un guide d'ions (4) peut être conçu de façon à se prolonger sans interruption d'un étage de vide (72) à un autre (73). Des ensembles individuels de sources de tension à radiofréquence, à courant continu +/- et à fréquence séculaire délivrent des potentiels aux tiges de chaque guide d'ions multipolaire et permettent ainsi la mise en oeuvre des fonctions d'émission d'ions, de piégeage d'ions, de sélection masse/charge et de fragmentation d'ions, de façon indépendante dans chaque guide d'ions. La présence d'une pression de fond élevée le long de l'ensemble linéaire des guides d'ions multipolaires permet la fragmentation des ions par Dissociation Induite par Collisions (CID) grâce à l'accélération axiale des ions d'un guide d'ions multipolaire vers un guide d'ions adjacent, ce qui est analogue à une fonction quadripolaire triple. Les ions peuvent également être fragmentés dans un ou plusieurs guides d'ions multipolaires au moyen d'une excitation à la fréquence de résonance CID, ce qui équivaut à une fragmentation des ions dans des pièges à ions quadripolaires à trois dimensions.
