Patent IT-1107739-B (IT)
Title: Urea synthesis from ammonia and carbon di:oxide - with two=stage thermal treatment of synthesis prod. and recycle of two separate streams
Inventor: PAGANI GIORGIO
IPC: C07C/
Filed: 1977-05-18
Granted: 1985-11-25
Abstract: Prodn. of urea by the double isobaric recycle method comprises reacting NH3 and CO2 at high mole ratio and thermal treatment of the synthesis product formed at about synthesis pressure in presence of an entraining gas. Improvement is that (a) thermal treatment is in two consecutive isobaric steps with virtually all residual carbamate decomposed in the first step and displacement of decompsn. products with a part of the excess NH3; and in the second the remaining NH3 is displaced by additional heat and injection of a current of CO2; and (b) gases from the first stage are recycled directly while those from the second subjected to condensation and purging with residual gas before recycling as liq. The urea prd. soln. is virtually free of CO2 and NH3 yet excessively large heat inputs are not necessary. Temp. fluctuations in the process can be avoided by controlling the two recycle streams.

Abstract: The axially movable seal face (9) of a rotary mechanical face seal e.g. for a ship's stern shaft, is sealed to its associated structure (3) and at the same time loaded axially, by the wedging action of a ring (11). This is urged radially between two oppositely inclined annular surfaces on bodies forming part of or associated with the member and the structure, either the ring or the surfaces or both being of resilient material. The ring could be a rubber O-ring (11) and the surfaces could be two further O-rings (7, 8). Alternatively the ring could be rigid, or the ring could be resilient but the other two surfaces rigid. In a modification one of the surfaces extends at 90 deg. to the axis of the sealing assembly.

Abstract: PCT No. PCT/US82/01608 Sec. 371 Date Jun. 19, 1984 Sec. 102(e) Date Jun. 19, 1984 PCT Filed Nov. 12, 1982 PCT Pub. No. WO84/02005 PCT Pub. Date May 24, 1984.A single mode optical fiber switch having a base (70) and a laterally slidable top (91). The base is composed of a quartz block (70) with a slight radius of curvature along its length supporting a silicon substrate (66) having a plurality of parallel v-grooves (68). The grooves are fitted with single mode optical fiber segments (64) and lapped to create a flat coupling surface (82) extending laterally across the base. The top (91) is composed of a quartz block with a single v-groove (93) holding a segment of single-mode fiber (95). This fiber (95) is lapped to create a flat coupling surface matable with the coupling surface on the base. The base (70) and top (91) are placed together such that the top fiber (95) may be selectively slid into and out of coupling alignment with any of the fibers (64) in the base (70) to form a discretely variable delay line. A single length of fiber (121) is wrapped around the base ( 70) in helical fashion with each loop being secured in one of the v-grooves (68). By coupling the top fiber (95) with different loops of the base fibers (121), different amounts of delay can be obtained. The delay line can be used to provide variable frequency response for notch and transversal filters.

Title: Fluid absorbing article with absorbent gel stripes - sepd. by capillary crepe areas for better spreadability
IPC: B32B5/24
Filed: 1976-08-18
Granted: 1985-03-25
Abstract: A body fluid absorbing article for use as sanitary towel, tampon or bayhs napkin has the absorbing material distributed in a certain pattern (stripes). The area between have capillary properties to direct the fluid flow from satd to non-satd. areas of the absorbing material. The absorbent is a polymer which swells in water and forms a gel such as a crosslinked carboxy alkylated starch deriv. The extremely good absorbent qualities of gel are thereby utilized more efficiently by spreading the effect from central to outlying areas. The strips which are free of absorbent act as temporary storage for fluid.
