Patent EP-0046876-A1 (EP)
Inventor: PREUSSER GERHARD DR DIPL-CHEM
IPC: C07C7/08
Filed: 1981-07-23
Abstract: A method for working up residues of an extractive distilling process for obtaining pure hydrocarbons. The residue from an extractive distilling column is fed to the about middle part of a distilling column. The hydrocarbons are distilled and removed at the head of the distilling column and the solvent is removed at the bottom of the distilling column. A sidestream is removed from the distilling column at a position above the feed plate for the residue from the extractive distilling column via a so-called reflux evaporator plate having an elevated level of liquid. The sidestream is heated by indirect heat exchange with the solvent flowing from the distilling column. The heated-up sidestream is fed back into the distilling column at a level at or above the reflux evaporator plate. The concentration of the solvent at the reflux evaporator plate is controlled by the amount of reflux at the head of the distilling column. The heating of the side stream reduces the heat requirement of the bottom boiler of the distilling column by about 35 percent.

Abstract: A medicated intrauterine device includes a preexisting contraceptive intrauterine platform (11) and an attachment (15) formed as a cylindrical sleeve (16) of base polymer containing a drug such as an antifertility agent. Local controlled release administration of the drug is added to the contraceptive effect of the preexisting platform. The attachment (15) can be made by centrifuging a medical grade of room temperature vulcanizing silicone rubber to remove reinforcing fillers therefrom. A selected quantity of the drug is mixed into the fillerless silicone rubber, and the drug and silicone mixture is injected into a multicavity mold. After the mixture sets and the sleeves (16) are removed from the mold, the sleeves are trimmed, then swollen by immersion in a solvent, and slipped onto the stem (12). An outer covering (17) over the sleeve (16) can control the drug release rate and impart greater strength to the fillerless silicone rubber of the attachment (15). The outer covering (17) can be a tube likewise swollen and slipped onto the sleeve (16) to tightly shrink thereon.

Abstract: In an illumination arrangement which includes a linear light transmitting array (16) the effects of gray borders on an imaging surface (24) are compensated for by locating a light-directing member (26) at at least one end of the linear transmitter entrance. In a first embodiment, reflective elements (26) are placed at the array ends so as to intrude (26a) a slight distance into the optical path. A portion of light from an illumination source (18) is reflected from these elements to eliminate unwanted edge borders on an underlying imaging surface. In a second embodiment, a portion of light from the illumination source is directed by total internal reflection along one of the prism surfaces into one end of the linear transmitter. This light is transmitted through the transmitter and dissipates the gray borders created by edge illumination of the document being copied.

Abstract: In the case of a hollow stick of shirred tubular casing wrapped in an expandable tubular net, as envisaged in particular for subsequent processing on an automatic sausage-filling machine, the tubular net (10) is made up of interlinked mesh threads (14, 16), running in axial direction and in circumferential direction, of which the mesh threads (16) running in circumferential direction consist of elastically stretchable material, whereas the axially running mesh threads (14) are resistant to stretching. This design makes possible in addition to the simple packing effect of the tubular net a controlled drawing-off of the casing material from the tubular caterpillar fold by fold during processing on the automatic sausage-filling machine, and there is no need for the special tying-off of the ends of the tubular net when enclosing the shirred tubular casing in the tubular net. <IMAGE>

Dans une seconde version, l'electrode de commande consiste en un conducteur a fente (94), le conducteur allonge revetu du dielectrique (11) etant noye dans la fente (96). Un potentiel variable de haute tension (25) entre le conducteur allonge (11) et l'electrode de commande induit une decharge a lueur dans une region d'air a proximite des deux conducteurs. L'electrode de commande peut jouer le role d'un organe de terre pour former un dispositif de decharge de la couronne par rapport a une surface voisine (20). En variante, l'electrode de commande peut etre maintenue a un potentiel desire (27) pour obtenir un dispositif de charge avec une tension limitee automatiquement. Les dispositifs de charge a effet de couronne de l'invention sont caracterises par une relation lineaire entre les courants d'ions de sortie et un potentiel d'extraction de courant continu. Dans d'autres versions du second dispositif de couronne, le conducteur a fente et le conducteur revetu d'un dielectrique peuvent etre remplaces par d'autres structures qui donnent une enceinte equivalente.
