Title: Process relating to ore benefication
Inventor: EVANS ARTHUR WALLACE
IPC: C22B34/12
Filed: 1961-04-14
Abstract: Titanium ores containing iron are treated with sulphur (elemental or combined) at elevated temperatures and the resulting mixture may be leached with mineral acid to remove iron sulphide.  The process is carried out using dispersed preferably fluidized material in an atmosphere of oxygen or oxygen and an inert gas.  The material may be ground before treating in the fluidized bed which may be partially made up of fine inert particulate material and to which a portion of the product may be returned.  The fluidized bed may be heated externally and part of the heat is supplied by burning some of the sulphur in oxygen. Waste sulphuric acid may be used in the leaching process wherein ferrous sulphate is produced and may be recovered. Sulphur and sulphur dioxide are recovered from the heating process which at preferably 600 DEG  C. and above is hot enough to vaporize the sulphur.  Excess sulphur is used and may be obtained from hydrogen sulphide or iron pyrites as well as elemental sulphur.  The sulphur and oxygen containing gases may be preheated before passing into the fluidized bed which may be a batch or continuous process. The acid leaching is preferably carried out using 15-25% acid at 60-85 DEG  C.

Title: Production of regenerated cellulose materials
IPC: D01F2/08
Filed: 1961-04-17
Abstract: Regenerated cellulose filaments are made by spinning viscose of viscosity at least 150 poises at 15 DEG C. of Y-value at least 40 and containing cellulose of degree of polymerization at least 400, in an aqueous acid bath containing 60-120 g./l. sulphuric acid, 100-250 g./l. of anhydrous sodium sulphate, 10-150 g./l. of anhydrous zinc sulphate and 1-40 g./l. of formaldehyde, stretching the spun filaments in the bath, stretching them further in a second dilute aqueous acid bath at high temperature, and then completing the regeneration of the cellulose without allowing the filaments to relax, either by winding them and subjecting the wound filaments to treatment in aqueous acid while in wound condition, or by treating them in a third acid bath and thereafter cutting them to staple fibre.  Preferably the degree of polymerization of the cellulose is between 500 and 800, the Y-value of the viscose is between 50 and 80 and its viscosity at 15 DEG C. between 200 and 400 poises.  The viscosity of the viscose and the degree of polymerization of the cellulose contained therein are determined on the viscose at the time of spinning. The viscose may also contain 1-40 g./kg. of formaldehyde and a modifier which is an amine, polyamine, a polyoxyalkylene compound or a condensation product of an amine and a dithiocarbamate in a proportion of 0,3-10% by weight relative to the alpha cellulose content of the viscose.  The coagulating bath may also contain a modifier which is an amine, a polyamine, a polyoxyalkylene compound or a dithio-carbamate, in a proportion of 0,1 to 10 g./l.  Specified coagulating bath temperatures range from 45 DEG -55 DEG C.  The filaments may be stretched 30-50% in the coagulating bath, and further stretched by 60-120% in the second bath.  In spinning continuous filaments, the spun filaments may be wound on bobbins and allowed to remain thereon in contact with acid until the Y-value is sufficiently reduced.  In making staple fibres, the bundle of filaments emerging from the second bath may be freed of carbon disulphide and fixed under tension in a hot acid bath and cut to staple fibre.  Filaments so made have an elongation less than 10% both in the dry state and in the wet state, and a very high modulus (3,25% elongation in the wet state under a tension of 0,5 g./denier). They have at least 80% skin and show secondary swelling between 50% and 80%.

Title: Improvements in or relating to hydraulic actuator systems
IPC: B23Q5/26
Filed: 1938-05-11
Abstract: 517,064. Hydraulic machines. WAHLMARK, G. A. May 11, 1938, No. 14055. Convention date, May 15, 1937. [Class 69 (ii)] An hydraulic actuating system provides means for driving through a hydraulic motor, a table or support for a machine tool or other driven member, pumping apparatus being employed with h governing mechanism controlling the liquid discharge by the pump to the motor and remote control means including a number of individually operable valves controlling the governing mechanism to determine the cycle of movement of the driven member. A normally open manual switch operates when closed the discharge of liquid. A dog-actuated switch is closed to maintain discharge, and a normally open dogactuated switch is closed to reverse liquid discharge for reversing direction of movement of the machine tool table or other member, As shown a constant delivery gear pump 13 is continuously rotated and draws o:l or the like from a tank 20 through a pipe 21 and ports 22, 23 and discharges through a port 24 and passage 25. The rate and direction of the output from the pump assembly is controlled by a series of valves 61, 70, 85 F2V, 16. The valve 61 is normally opened by pressure from the pump 13 against the action of a spring 63 and allows liquid to pass to the reservoir. The back pressure caused by the valve 61 is so small that liquid cannot open inlet valve of pump 14. The valve SV controls hydraulic blocking of the valve 61 and liquid from pump 13 opens the valve 70 against its spring, allowing some of the liquid to pass to reservoir. The back pressure caused by the valve 70 is sufficiently great to open the inlet valve to the pump 14 but not to open the outlet valve thereof, hence the pump 14 acts to boost pressure and meters flow at a " feed rate." The valve TV controls hydraulic blocking of the valve 70 and liquid from the pump 13 passes wholly through the pump 14, which passes the liquid without metering it at a "traverse rate." The valve 85 normally spring closed and controlled by valve F1V can admit liquid to act on piston 41 to completely decrease the delivery of the pump 14. The valve F2V controls the supply of liquid to act on a piston 49 to partially decrease delivery of the pump 14. The valve 16 controls direction of operation and is controlled by the valve RV. The governing and pumping in a single unitary structure is that disclosed in Specification 516,565 and the unitary generating and control device is also disclosed therein.
