Patent IT-1250174-B (IT)
Title: Elimination of the stuffing box, stuffing box fixing bolts, and impregnated cord or tow with the aim of reducing the number and slowness of assembly of the components of a gate valve for fluid control by simultaneously replacing the seal with a ceramic/graphite system inserted in the cover
Inventor: FONTANA LUDOVICO
IPC: F16L/
Filed: 1991-06-07
Granted: 1995-04-03
Abstract: TECHNOLOGICAL FIELD: Mechanical/Hydraulic. TECHNICAL PROBLEM: To reduce the number of components and slowness of assembly of a typical gate valve, eliminates a coupling surface which over time can become a source of leakage of the liquid, and simultaneously achieve complete fluidtightness using ceramic graphite seals. CHARACTER OF THE INVENTION: It is well known that a gate valve for use in fluid pipes traditionally consists of a body, and a stuffing box that compresses an impregnated cord or tow in the seat and around the control shaft, thus preventing leakage of the fluid but only for a short while. The invention consists in a particular configuration of the colour which does away with the stuffing box, the stuffing box fixing bolts and the impregnated cord or tow. Fluidtightness inside the cover is provided by a set of ceramic/graphite seals which prevent all leaks for a long period of time. USE: Industrial manufacture of gate valves without stuffing boxes while achieving complete fluidtightness. <IMAGE>

Granted: 1995-03-30
Abstract: A disposable absorbent article such as a diaper provided with a continuous upper layer (5), an absorbent element (6), an impermeable plastics sheet (9), elastic parts (10) positioned along the lateral edges to either side of the absorbent element (6) and two elasticated flaps (11) positioned inwardly of the elastic parts (10). Each flap (11) is formed out of the continuous upper layer (5) by use of an elastic element (14) fixed along its entire length to the inner surface of the continuous layer (5). The continuous upper layer (5) is liquid-permeable in the zone between the two elastic elements (14) of the flaps (11) and impermeable in the two adjacent zones located between the elastic elements (14) and the lateral edges of the absorbent article. In use, the elastic elements (14) contract, lifting the continuous upper layer (5) off the underlying surface, at least at the crotch area, forming two longitudinal barriers which are impermeable on the side facing the lateral edges of the absorbent article, thus ensuring a more efficient containment of lateral leakage of liquids and solids in an absorbent article of simplified structure.

Title: Establishing telecommunications call paths between clustered switching entities
Inventor: HILLER THOMAS LLOYD
IPC: H04L12/56
Filed: 1992-12-16
Granted: 1993-12-11
Abstract: In accordance with the principles of this invention, Pulse Code Modulation (PCM) signal streams are converted into Asynchronous Transfer Mode (ATM) cells for switching and transmission across a telecommunications network. Each cell carries one PCM sample of up to 48 different voice connections, the voice connections selected from the PCM data streams because they have a common destination. The cells are transmitted over ATM virtual circuits, each circuit transmitting one cell every 125fs. Advantageously, ATM transmission systems interface with PCM systems without adding appreciable delay and without requiring additional buffering. Advantageously, new voice paths can be established most of the time by using availabled slots in the cells of existing virtual paths. This application relates to the use of the principles of this invention for implementing a large switching system or a cluster of highly interconnected smaller systems.
