Title: Liquid pulsation damper
IPC: F04B11/00
Filed: 1958-10-28
Abstract: 838,592. Liquid pulsation dampers. NATIONAL SUPPLY CO., and OIL WELL ENGINEERING CO. Ltd. Oct. 28, 1958 [April 21, 1958], No. 34451/58. Class 102(1). [Also in Group XXIX] A pulsation damper for reducing the surges in the delivery of a reciprocating pump comprises a hollow body member 1 having an opening 14 in which is fitted a cylinder 20. A piston 19 slides in the lower part of the cylinder and is connected by a stem 28 to an upper piston 21 which is a loose fit in the cylinder and defines a chamber 22. A valve member 23 is secured to the lower end of the piston 19 and is urged away from its valve seat 11, in a second opening 10, by a spring 26. The opening 10 communicates with the liquid flow which passes from inlet 3 through a filter 5 to the outlet 8. In operation the hollow body 1 is charged with air which flows from pipe 18 to the chamber 22 and round the side of piston 21 causing a pressure drop across this piston which moves the piston assembly against the spring 26 to close the valve 23 and air then flows into the hollow body 1 through ducts 27, 27a. As liquid flows through the inlet 3 the valve 23 remains closed until the pressure of the liquid is substantially equal to the pressure of air when the valve opens and liquid is free to flow into the body 1 causing the air to compress. When the liquid delivery stops the liquid is forced from the body 1 by the air pressure, the body being so shaped to assist in this draining, and when the air pressure in chamber 1 falls below the air supply pressure in pipe 18 the valve 23 will close as above and the hollow body be recharged with air.

A leather replacement sheet material comprises a compressed layer which may be from 10 to 70 mls. thick, having a network of interconnecting pores and comprising non-woven matted fibres bound together by an initially thermoplastic extensible polymeric binder, coated on at least one surface with an extensible abrasion resistant polymeric material having perforations therein connecting with the pores of the compressed layer, the sheet material exhibiting water vapour permeability, scuff resistance, and flexibility. The polymeric binder may be plasticized and may be an elastomer (long list given) selected such that the softening point of the binder is at least 50  F. below that of the fibres. The fibres may be about 1.5 inches in length and about 3 denier. The polymeric binder-fibre weight ratio may be within the range 30 : 70 to 70 : 30. The same or substantially the same material may be used for the binder and the polymeric material of the coating. The coating may have a thickness of between 1 and 20 mls. and may have between 300 and 30,000 perforations per square inch. The perforations may be effected by needle punching using needles of between 1 and 10 ml. diameter. The hot pressing may be effected under a pressure of 50 to 1500 pounds per square inch and at a temperature above the softening point of the binder but below the softening point of the fibres. The network of pores may be formed (i) by stretching the sheet material from 10 to 50% in at least one direction thereby causing the fibres to break away from the binder as described in Specification 736,604, [Group IV (b)]; (ii) by soaking the sheet material in a liquid at a temperature sufficient to swell the fibres and deform the binder and shrinking the fibres by cooling; or (iii) by making the base of fibres of which 40 to 70% by volume are soluble (list given) and treating the sheet material with a solvent therefor. Lists of coating and fibre materials are given. Specifications 461,236, 535,262, 542,414, 553,733, [all in Group IV], 711,279, 711,280, 796,041, [all in Group IV (a)], and 811,444 also are referred to.
