Patent EP-0337342-A1 (EP)
Inventor: BURK HERMANN DIPL-ING FH
IPC: G03F7/42
Filed: 1989-04-10
Abstract: A photoresist stressed by etching with fluorine-containing etching gas, in particular, can only be stripped wet-chemically in common strippers with extreme difficulty and by no means completely. A process is proposed in which an electrolysis is performed to assist an alkaline stripper bath, the substrate (1) carrying the stressed photoresist structure (5) being connected as cathode. The gases produced during the electrolytic decomposition of water in the immediate vicinity of the substrate surface or at the exposed metallic surfaces (3, 4) bring about a complete stripping of the photoresist structure (5) already incipiently dissolved by the alkaline bath. In particularly difficult cases, the process can be combined with an additional stripping process, for example a "cleaning process" in oxygen plasma. The new process is simple and, in addition, can be carried out more inexpensively and more quickly than known processes. …<IMAGE>…

Abstract: A continuous cycle peritoneal dialysis system and process is disclosed which includes a source (14) of sterilized dialysis fluid, and an inflow line (34) and outflow line (35) connected to a catheter (26) implanted in the peritoneal cavity (28) of a patient. A fill pump (B) pumps sterilized dialysis fluid from the source to the catheter through the inflow line during a fill cycle. A drain pump C pumps fluid from the catheter to a drain through the outflow line during a drain cycle. A function of a volume of the dialysis fluid in the peritoneal cavity is detected by a manometer (D). A process controller (A) controls the fill and drain pumps in response to signals from a high fluid level detector (50) and a low fluid level detector (52) on a fluid column tube (48) to pump a calibrated fill volume of fluid into the cavity and a calibrated drain volume of fluid out of the cavity continuously in alternating fill and drain cycles in a manner that the fluid flows through the cavity generally with zero dwell time. In the process, an inflow volume of dialysis fluid pumped into the cavity is metered (36b) and an outflow volume of fluid pumped out of the cavity is metered (44b) to determine the amount of fluid removed from the patient by comparing the inflow and outflow volumes. A glucose pump (E) is connected to a source (70) of glucose and to the inflow line for delivering a regulated amount of   glucose in response to a comparison of the metered inflow and outflow volumes.

Abstract: A sliding annular seal having a counter-ring (15), which rotates with the shaft, in the end face (14) of which counter-ring containing the sliding sealing surface (17) a plurality of grooves (20) is constructed which, starting from their open groove ends connected to the space (7) having the lower pressure (p2), extend at acute angles to radial lines passing through the shaft axis (1), their closed groove ends (32), located at the rear in relation to the direction of rotation of the shaft, being arranged adjacent to the space (6) containing the fluid to be sealed off and having the greater pressure (p1), but being in connection with this space only via the groove-free sealing gap. Starting from the closed groove end (32), the base line of each groove (20) increases its distance (A) from the sliding sealing surface (17). At a transition point (36), the gradient  DELTA A/ DELTA s increases abruptly. The groove parts of minimum depth located between the closed groove ends (32) and the transition points (36) effect the setting up of fluid pressure cushions separating the sliding sealing surface (17). The groove parts of greater depth located between the transition points (36) and the open groove ends return the fluid and prevent it from departing from the sealing gap region. <IMAGE>

Abstract: The invention provides a novel copolymer comprising 25-75 mol% of a fluoroolefin such as CTFE or TFE, 10-70 mol% of an alkene such as ethylene or propylene, 3-40 mol% of a hydroxyl-containing allyl ether such as ethylene glycol monolallyl ether and 0-20 mol% of a carboxyl-containing monomer such as vinylacetic acid. This copolymer possesses favorable properties character­istic of fluororesins, is soluble in organic solvents including aromatic solvents low in polarity, such as xylene, and is curable at relatively low temperatures. The copolymer is useful particularly as a paint vehicle. The water repellency of the copolymer in cured state can be enhanced by incorporating a fluorine-containing surface modifier in the copolymer.

Abstract: This invention relates to a disposable syringe for once-only use. The syringe comprises a hollow cylinder which carries a needle at one end and houses a plunger connected to one end of a shaft, the other end of which is provided with a manually operable shaped head. The diameter of this head is a maximum in proximity to that portion adjacent to the shaft and reduces gradually towards the free end of the head. The shaft length is such that when the plunger has been pushed to the bottom of the cylinder, the maximum diameter portion of the head is housed within the cavity of the cylinder, from which the decreasing diameter portion of the head projects, so that the shaft head can no longer be gripped by the fingers in order to move the shaft backwards and reuse the syringe.

Abstract: Plural sensor prisms and associated optical-­fiber circuits are arrayed as a single vertical stem by which the individual prisms serve for response to each of a plurality of different liquid levels. Each prism is formed of light-transmitting plastic material which can be injection-molded to precision dimensions. The body configuration is such as to adapt to arrayed interconnection with tubular members, also of plastic, and bonded at telescoping fit of each prism to the tubular member or members to which it is connected. The prism configuration relied upon for sensed response to the presence of immersing liquid (as compared to air) is a solid region having an exterior profile which includes a downwardly convergent conical surface portion at least at spaced locales which are at equal but opposite offset from the cylindrical body axis, wherein the geo­metric apex angle of downward convergence is 90 degrees. As long as a given prism is exposed to air, a large amount of light is transmitted (by reflection within the prism) from a transmission optical fiber to a receiving optical fiber. But when immersed in a liquid, a portion of the light from the transmitting fiber is refracted into the liquid, resulting in a clearly detectable decrease in the amount of light coupled to the receiving fiber.
