Title: Process for the treatment of synthetic thread
IPC: D02G1/02
Filed: 1953-05-22
Abstract: 737,039. Yarns. BILLION, J. May 22, 1953, No. 14545 /53. Drawings to Specification. Class 120(3). A method of preparing synthetic threads having permanent undulations comprises the steps of highly twisting two separate threads in opposite directions, allowing the threads to contract and produce deformations, heatsetting the threads, de-twisting them to the same low twist and then plying the threads together with a twist of the same value as the low twist but in the opposite direction and greater than 125 turns per metre. In an example, a thread of 45 denier, 13 filament polyhexamethylene adipamide having 20 turns per metre of left twist was twisted with 2,500 turns per metre left and an identical thread was twisted with 2,500 turns per metre right. Both threads were then subjected to a temperature of 110‹C. at 95 per cent relative humidity for 45 minutes and allowed to shrink. After drying, the lefttwisted thread was de-twisted to 700 turns per metre left and the right-twisted thread completely de-twisted and re-twisted to 700 turns per metre left. The threads were then plied with 700 turns per metre right. Specification 660,993 is referred to.

Title: Improvements in or relating to a fluid pressure energy translating device
IPC: F04B1/32
Filed: 1965-04-06
Abstract: 1,088,914. Fluid-pressure servomotor systems. T. BUDZICH. April 6, 1965 [April 6, 1964], No.14650/65. Heading G3P. In a control system for maintaining the discharge pressure of a swashplate pump constant at a selected value, the discharge pressure acts via line 174 on a spool 86 loaded, via spring 116, by discharge pressure acting on a piston 126 and by mechanical means through lever 156. The swashplate (16, Fig. 1 not shown), is biased to a maximum stroke position by a spring 62 (Fig. 2), acting on a rocker 24 connected to the swashplate by a splined shaft 28. A piston 72 acts in the opposite direction on the rocker and its cylinder 74 is connected to a chamber 92 adjacent the spool via line 168. The effective area of piston 126 is less than that of the spool so that when the pressure via line 174 on the latter overcomes the loading the spool moves to the left to admit fluid to cylinder 74 via groove 110, ports 88, 90, chamber 92 and lines 168, 170, thereby decreasing the stroke of the pump. At the same time, the fluid enters a bore 80 via spool passages 112, 114, 124, where it acts on both the piston 126 and the spool. By this arrangement, both the spool and piston 126 are maintained in a state of floating equilibrium with the application of a small external force to the latter, i.e. a balance exists between discharge pressure on one end and spring bias supplemented by the control pressure in bore 80 on the other end. To select a higher controlled discharge pressure the spool is moved to the right by the application of a force or lever 156, thereby connecting cylinder 74 and bore 80 to exhaust in the rocker housing via spool groove 102, ports 100 and line 171.

Title: Improvements in or relating to the production of cellulose
IPC: D21C5/00
Filed: 1945-06-11
Abstract: Raw cotton linters are purified by a process comprising treatment with strong caustic alkali at atmospheric temperatures such that substantially no mercerization occurs, subsequent treatment in an alkali, of lower concentration, at an elevated temperature and under superatmospheric pressure, and treatment with an oxidizing bleach. Raw cotton linters are steeped in solutions of caustic soda of 6-15 per cent concentration at a temperature of 5-50 DEG  C. for 10 mins. to 4 hours.  The steeping liquor is drained off and may be followed by an oxidizing bleach. The cotton linters are then digested in dilute caustic soda at about 400 DEG  F. and under the corresponding saturated steam pressure.  If desired, digestion may be performed in the presence of turkey red oil, FF wood rosin, sodium abietate, tall oil, disodium-sulphoethylphenyl stearate, or isopropyl naphthalene sodium sulphonate.  The bleach treatment may involve the use of alkaline or acid solutions of available chlorine such as free chlorine, hypochlorites, chlorites; peroxides; peroxygen compounds or permanganates and the like.  In one example, raw cotton linters steeped in a 9 per cent solution of sodium hydroxide at 25 DEG  C. for 45 minutes are separated from the steep liquor, washed, treated with a dilute solution containing available chlorine (such as hypochlorite) for 1- 1/2 hour, washed and then digested in a 2.5 per cent sodium hydroxide solution, containing 0.8 per cent by weight turkey red oil, for 3 hours at about 275 DEG  F. and a steam pressure of about 30 lbs. per square inch.  The washed linters are then subjected to a multistage bleaching process.

Abstract: 560,836. Variable-pitch propellers. BOAST, J. E., and BEARD, S. W. G. Oct. 26, 1942, No. 15032. [Class 114] In a variable-pitch propeller with hydraulic pitch-varying means and an auxiliary feathering pump electrically driven, a switch 19 maintains a closed circuit controlling the motor in response to the flow of liquid from the feathering pump 2. The form of switch shown in Fig. 2 comprises a contact member 71 slidably mounted on the valve stem and pressed towards contact position by a spring 81. Flow of liquid from an inlet 66 opens the conical seated valve and causes contact; when the flow ceases on attainment of the totally feathered position, the high pressure of liquid acting on the differential valve area returns the valve and breaks the contact. The valve may be replaced by a plug valve. The controlling system shown in Fig. 1 is similar to that of Specification 560,833.
