Title: Improvements in valves suitable for lubricating systems
IPC: F16N25/02
Filed: 1957-05-03
Abstract: 845,015. Fluid-actuated valves. TRAVIS, R..W. May 5, 1958 [May 3, 1957], No. 14142/57. Class 135. A device for feeding lubricant &c. alternately to a pair of outlets 11, 12 and arranged to change over from one outlet to the other in response to rise of pressure in the said one outlet consequent upon the completion of delivery of lubricant from each of a number of feeders connected to that outlet comprises interlocking main and auxiliary valves 15, 16 respectively. With the parts positioned as shown lubricant entering the housing at 10 passes a central, reduced portion 161 of the valve 16 and has access to a passage 25 communicating with a chamber at the right-hand end of the valve 15 whereby the latter is held in position to allow lubricant, after passing through a chamber 18 containing interlocking balls 19 for the valves 15, 16 to pass to the outlet 11. Rise of pressure in this outlet is communicated through a passage 111 raising a spring-loaded piston 20 to permit flow through a passage 112 to the righthand end of the valve 16, causing the latter to move to the left and place the left-hand end of the valve 15 in communication with the inlet 10 and the right-hand end in communication with a low-pressure passage 13 through a reduced portion 164. The balls 19 prevent movement of the valve 15 until the valve 16 has completed its movement. When the piston 20, or a similar piston 21 connected by a passage 121 to the outlet 12, is in its lowermost position it connects the end of the valve 16 that is not pressurized to a low-pressure passage 14 or 13. The passages 14, 13 connect with the intake of the pump feeding the inlet 10.

Patent GB-561344-A (GB)
Title: Improvements in and relating to synthetic linear polyamide filaments, threads and the like
IPC: D06M23/00
Filed: 1942-10-12
Abstract: Filaments, yarns, threads, cords, ribbons, tubes, or similar articles made of synthetic linear polyamides with oriented micelles are subjected while under tension to treatment with a solution of a phenol in a non-solvent for the polyamide, the solution being of insufficient concentration to dissolve the filaments.  The phenol is then removed by means of a solvent for the phenol, e.g. by means of water, preferably heated, and the materials are dried while still under tension.  The treatment is carried out in order to reduce the thermo-extensibility factor, and to improve the stiffness and impact-resistance.  Treated filaments may be used in making strings for tennis rackets, cords for tyres, parachute shroud lines, and parachute cloth.  The polyamide micelles may be oriented by applying tensile or compressive stress to the filaments or other articles as by the operations of cold drawing or cold rolling.  In an example, a polyhexamethylene adipamide yarn is wound under tension on a bobbin and immersed in a 4 per cent aqueous solution of phenol for 5 minutes.  It is removed from the solution, immersed in boiling water for an hour and then dried at 65 DEG  C.  In another example, the phenol is removed by soaking the yarn in water at room temperature for 24 hours.  The filaments, yarns and other articles may be made from compositions containing polyamides and plasticizers, resins, cellulose derivatives, anti-oxidants, dyes, pigments, or fillers. Resins of the type obtained by treating phenol or its alkyl derivatives, such as p-tert.-butylphenol or o-cyclohexylphenol, with formaldehyde may be added to the polyamide composition.  Such additions increase the water-resistance and stiffness of the filaments.  Preferably, a lowly polymerised phenol-formaldehyde which is non-heat-hardening is used.  Instead of treating the polyamide materials with a solution of phenol itself, solutions of o-cresol resorcinol, chlorophenol, nitrophenol, aminophenol, monoethers of dihydroxy or trihydroxy phenols, salicylic acid, or other phenolic substances may be used.  Instead of using water as the non-solvent diluent, there may be used alcohols or other organic liquids.  The phenol may be removed from the treated materials by treatment with water followed by drying in air or inert gas or in a vacuum, or it may be removed by extraction with alcohol or with dilute caustic alkali.  Preferably, the filaments or other materials are soaked in water prior to treating them with the phenolic solution. Specifications 461,236, 461,237, 501,197 and 521,946 are referred to.
