Abstract: ABSTRACT OF THE DISCLOSURE                The present invention relates to a glass or plastic device used to water potted-plants, continuously and unaided for a period of two or more weeks.  The plant sits in a pre-determined depth of water in the center of this device which consists of two preferably identical semi-cylindrical water reservoirs that when placed together form a upright hollow cylinder that sits into a third embodiment that acts as a catch basin which serves to elevate the water reservoirs to the required water level and hold them into position.  Water flows upward to the plant, which sits in its original pot in the center of the catch basin, through the soil by diffusion via small holes at the bottom of the pot. The depleted water from the catch basin is replenished only when the water level drops, by the cylindrical water reservoirs through a small hole placed at the bottom of these embodiments, which also regulates the water level in the catch basin.  When the water is depleted from the water reservoirs, these are filled, one side at a time and replaced into the catch basin.

Abstract: Abstract of the Disclosure A silicone-based composite coating system for a glass optical fiber, the system comprising a silicone polymer undercoating component and a silicone-polyimide block copolymer overcoating component, is provided.  The coating system can be applied entirely on-line, improves the handling characteristics of the fibers over conventional silicone-coated fibers, offers an excellent combination of optical and elastic properties, and does not compromise the high-temperature operating characteristics of silicone-based coating systems.  Preferably, the silicone polymer undercoating is applied by a rapid on-line coating process wherein the components of the two-package silicone coating system are continuously combined, mixed and applied to the fiber using novel apparatus which continuously delivers the coating to the liquid coater at a rate corresponding to the rate of coating application to the fiber.

Granted: 1989-11-20
Abstract: The disclosure relates to a rotary pump especially for corrosive liquids including an impeller rotating in a working chamber. A spirally wound duct leads from one surface of the working chamber to the outlet pipe of the pump. The upstream end of the duct obliquely enters the working chamber, whereby the end portion of the duct is laterally open towards the chamber and forms a channel in the wall of the chamber. The duct winds helically around the rotation axis of the impeller, having an inside wall at a progressively decreasing radial distance from said rotation axis and a progressively increasing pitch when viewed in the direction of the flow. A feature is the provision of the wound duct in the form of a helix as an open groove formed on the outer surface of a solid stator body and closed by an encompassing casing. A further feature is the provision of a relatively loose, elongated drive shaft from a motor to the pump impeller disposed within a guide tube and a circumferential clearance between the shaft and the tube for leakage flow of liquid being pumped to lubricate the shaft wherein a bypass port is provided in the guide tube for return of the leakage flow upstream of a restriction in the clearance. The restriction increases pressure in the clearance to dampen lateral oscillation of the shaft in the tube. No seals are used for the shaft thereby precluding the tendency of seals to stick during prolonged rest periods.

Abstract: A process for the isomerization of C4-C6 paraffins with good stability and high conversion that uses a highly active catalyst to isomerize the feed (10) in the presence of very little hydrogen (14) which is selected so that the hydrogen to hydrocarbon mole ratio of the effluent (46) is 0.05:1 or less, and hydrogen is not recycled. Continued operation at low hydrogen concentrations in the reaction is made possible by the remarkably low coking tendency of the catalyst, especially during periods of temporary sulfur deactivation. The low hydrogen to hydrocarbon mole ratio feature simplifies the process and makes it cheaper to operate by eliminating facilities for the recovery and recycle of hydrogen. The catalyst comprises alumina having 0.01 to 25 wt.% of platinum, and from 2 to 10 wt.% of a chloride component. The isomerization conditions in isomerization zone (16) include a temperature of 40 to 235<o>C, a pressure of 7 to 70 barsg and a space velocity of 0.1 to 10 hr<-><1>. A chloride concentration of 30 to 300 ppm is maintained in the reaction zone (16).
