Patent EP-0363800-A1 (EP)
Inventor: MAY MARVIN M
IPC: B66D3/04
Filed: 1989-10-04
Abstract: An improved cable hoist apparatus (10) has a sheave (22) movably connected relative to a frame (50) to bias the cable (12) in a circumferential groove (58) in the sheave (22). A biasing means on the frame compresses the cable (12) in the sheave groove (58) with the amount of force depending upon the tension in the cable (12). In this regard, the sheave (22) is positioned relative to the frame (50) as a function of the cable tension such that the greater the cable tension, the greater the biasing force on the cable. However, the biasing means can include a plurality of rollers (62, 94) to regulate the biasing force. A reeving spring (142) can be used in conjunction with the biasing means to allow reeving of the hoist (10) when the cable is unloaded. The hoist apparatus optimally incorporates certain advantageous safety features (124, 162....). These include a cable brake activated and released depending upon the position of the sheave and a motor shutoff as a function of overload and/or underload.

Abstract: Dans l'application préférée pour la préionisation de lasers TE, en particulier les lasers excimers, le tube à rayons X plasmique (ER), que l'on peut également désigner sous le nom de tube à ions à chambre unique, comprend un boîtier longiligne en forme de caisse (G) à l'intérieur duquel est agencé une cathode évidée (K) également longiligne et de section transversale approximativement en U, dont le côté ouvert est tourné vers la cible de rayons X sous forme de feuille imperméable aux gaz. Entre la cible des rayons X (1) et la cathode évidée (K) se trouve une électrode d'amorçage longiligne en forme de fil de fer (11). En appliquant une tension ou impulsion de tension positive à l'électrode d'amorçage (11), on crée autour de cette dernière un champ électrique sous l'influence duquel les électrons présents à cause du rayonnement ambiant sont forcés de suivre des trajectoires longues et hélicoïdales et ionisent ainsi des atomes de gaz. Des avalanches d'électrons se forment et amorcent la décharge du fil. En appliquant à la cathode évidée (K) un tension d'accélération typique d'entre 60 kV et 120 kV au maximum, on extrait des ions (i+) du plasma à basse pression (3) et on les accélère contre la cathode évidée (K). Au moment de l'impact des ions de la cathode évidée (K), des électrons secondaires sont émis et accélérés dans le sens opposé, formant le faisceau d'électrons (E), qui, en venant heurter la cible de rayons X (1), produit le rayonnement de freinage de rayons X (X). Ledit tube de rayons X plasmique convient aussi comme base pour un canon électronique: il suffit pour cela que la feuille qui recouvre l'ouverture dans la paroi de support de la cible et qui sert de fenêtre à électrons soit conçue de manière à laisser passer les faisceaux d'électrons.

Abstract: 1. Zirconium dioxide powder which has optionally been stabilised, and process for its preparation. 2.1 The use of aqueous solutions and the isolation of precipitates are substantial disadvantages in the processes, practised to date, for the preparation of zirconium dioxide powders. In addition, the products often do not have the desired flow, compression and sinter properties owing to an inhomogeneous distribution of the stabiliser and the presence of large crystallites and agglomerates. 2.2 By melting zirconyl chloride, optionally with a stabiliser, and reacting the chloride with gaseous ammonia, evaporating off water and any hydrogen chloride, calcining the reaction product and removing ammonium chloride by sublimation at elevated temperature and optionally milling the calcined product, an optionally stabilised zirconium dioxide powder having good properties can be prepared without the use of the disadvantageous process measures. 2.3 The optionally stabilised zirconium dioxide powder is suitable for the production of sintered articles which can be exposed to high mechanical and/or thermal loads.
