Title: Check valve
Inventor: YAINDL CHARLES
IPC: F16K47/00
Filed: 1986-07-21
Granted: 1990-09-25
Abstract: IMPROVED CHECK VALVE An improved check valve is disclosed, which prevents the valve disk from slamming against the valve seat when the fluid flow in the line is suddenly reversed. The valve includes a disk and a seat, the disk being movable towards and away from the seat in response to pressure changes in the line. The disk, together with a central member, defines a chamber which becomes filled with fluid when the disk moves away from the seat. When the direction of flow in the line is suddenly reversed, causing the disk to move back towards the seat, the disk is cushioned by the fluid in the chamber, and does not slam against the seat. In one embodiment, an orifice is provided, spaced apart from the central bore of the valve, through which the fluid in the chamber can slowly and steadily leak out. In another embodiment, the orifice is provided in the disk of a pilot valve, which is a small check valve mounted at the inlet end of the main valve. In either embodiment, the orifice causes fluid to leak out of the chamber in a controlled manner. The fluid in the chamber therefore acts as a dashpot to retard the movement of the disk towards the seat. The amount of damping of the dashpot is determined by the size of the orifice.

Abstract: Abstract A system for the collection of solar radiation and the recovery of thermal energy therefrom includes solar radiation receiver means at or near the focus of a solar radiation concentrating means for absorbing the solar radiation, converting it to thermal energy and transferring the thermal energy to ambient air drawn over the receiver means and, thereafter, directed to an energy reclamation unit.  In the energy reclamation unit the heated ambient air deposits a portion of its thermal energy in regenerators, from which it is recovered by a compressed air stream, and transfers a portion of its thermal energy to a power fluid.  The thermal energy of the ambient air is reclaimed from the compressed air stream and the power fluid as shaft work in expansion turbines.  In a preferred embodiment, the solar radiation receiver means comprises a high temperature resistant, porous, convex enclosure having inner and outer porous, convex surfaces arranged in spaced  apart  nested  relationship  for  defining therebetween an annular space which is randomly filled with a plurality of close to ideal black body solar radiation absorbing elements.

The adhesive coated substrate is easily removable from the contact surface by manually lifting it therefrom.  The adhesive permits readherence of the adhesive coated substrate to the same or different free contact surfaces.  An adhesive coated paper substrate will readhere many times to free paper contact surface.  The preferred gelled adhesive product is formed of an aqueous dispersion of components which include a rubber such as natural rubber latex component, a friction reducing agent, a tackifier, an antioxidant, a gelling agent and surfactant. Preferred classes of tackifiers are anionic aqueous dispersion of hydrogenated esters of rosin and anionic aqueous dispersion of esters of hydrogenated rosin.

Abstract: In a circuit arrangement for PCM telecommunication facilities, especially PCM long distance exchange facilities with several synchronous pulse clock controlled transmitters for common transmitting chanel, information from different transmission processes flows over a transmitting channel common to all transmitters. In addition to the transmitting channel, a test channel is provided. For the prevention of simultaneous transmission and a co-mingling together of information, each transmitter transmits its own binary coded address to the transmitting channel always before a message as well as to the test channel and receives back the total information after combining on the test channel for comparison, bit-by-bit with the actual address information transmitted by it. In the event of accidental simultaneous transmission start by a transmitter, in case of character inequality on the test channel between two simultaneously transmitted bits, the binary character of the one type always asserts itself against the binary character of the other type. A transmitter interrupts its transmission in the event of character inequality. The assertion principle is limited to test channels while the transmission of both types of binary characters to the transmitting channel is relatively low ohmicly.
