Abstract: 597,996. Hydro'- pneumatic shock - absorbers. AUTOMOTIVE PRODUCTS. CO., Ltd., and FOSTER, S. Aug. 27, 1945, No. 22031. [Class 108 (iii)] In a liquid-damped, telescopic, shock-absorber strut of the type comprising a hollow plunger 11 containing a resilient unit; and an associated cylinder 10 from which liquid is transferred on compression to the plunger 11 through a flow-restricting orifice or orifices, radial by-pass ports 26 disposed in a sleeve 21 formed on the inner side of the plunger 11 are controlled by the cylindrical surface of a piston valve 32 which is spring urged to close the ports and is subjected to a pressure differential due to flow through the orifice or orifices. In the construction shown these two orifices are formed, one 37 in a closed conical head portion 35 of the piston valve 32, and the other 42 in a closure plug 41 of the other end of the sleeve 21. The plug 41 forms an abutment for a spring 38 which urges the piston 32 to cover the ports 26 and drive the head portion 35 on to a conical seating 23. In operation, on compression at a low plunger speed, energy is absorbed by liquid-flow through the orifices 37, 42 and air is compressed above a floating piston, not shown, in the plunger 11. At an increased plunger speed due to an increased pressure differential on either side of the orifice 37, the piston 32 rises against the spring 38 and its full diameter is then exposed to the cylinder pressure. The piston then moves quickly upwards and exposes the ports 26 which are interconnected by a channel 27. On rebound, liquid can pass through passages 43 in the plunger which are controlled by a spring loaded flap valve 44. The damping orifice or orifices may alternatively be formed in the plunger.

Title: Improvements relating to process for electrolytically regenerating alkaline wash solutions used for removing hydrogen sulphide
Inventor: NICKLIN THOMAS
IPC: C10K1/12
Filed: 1962-06-08
Abstract: Alkaline wash liquors containing at least one anthraquinone disulphonic acid in alkali metal salt form, which have been used in liquid purification processes for removal of hydrogen sulphide from gases or liquid hydrocarbons and which contain salts of oxy acids of sulphur and/or of thiocyanic acid, are regenerated by passing D.C. through the liquor and between two electrodes separated by a porous material to prevent mixing of the solutions around each electrode. Typically the alkaline wash liquor contains alkali metal, e.g. sodium ammonium, vanadate in addition to the sodium salt of anthraquinone-2:7-disulphonic acid. After use in the purification plant the liquor contains also sulphate, thiosulphate, carbonate, and bicarbonate ions and is fed continuously through the cathode compartment, where its alkali content is raised, back to the purification plant; while the flow of used liquor through the anode compartment is adjusted so that its thiosulphate content approximates that which can be decomposed by electrolysis which is effected at 60-70 DEG C. with a current density of 2 amps/sq. in.  The effluent acid anolyte is then neutralized with lime and filtered and then returned to the wash liquor circulation.

Title: Process for producing polymer latices
Inventor: PATON CUMMING
IPC: C08F2/18
Filed: 1961-06-20
Abstract: A process for the production of a polymer latex of controlled particle size, comprises a first stage in which an aqueous dispersion of a polymer containing initiating groups is produced by polymerizing in an aqueous emulsion an ethylenically unsaturated monomer using an initiator containing two initiating groups, and a second stage in which in the substantial absence of initiator a further quantity of the same monomer is added and polymerized under the influence of the initiating groups of the polymer produced in the first stage. High solids latices may be obtained. Latices containing small and large particles may be obtained by adding a conventional catalyst near the end of the second stage.  In an example styrene is polymerized using p-diisopropylbenzene dihydroperoxide as initiator in media containing soap, sodium pyrophosphate, fructose and ferrous sulphate. The latices find application as coating compositions.
