Title: Improvements in or relating to the preparation or treatment of liquids for use in the manufacture of artificial silk
IPC: D01F2/04
Filed: 1928-07-04
Abstract: 319,841. Brysilka, Ltd., and Schubert, F. W. July 4, 1928. Ammoniacal-copper cellulose solutions.-The liquid used as coagulant in the stretch spinning process for the manufacture of artificial silk is flashed at ordinary temperature through a vacuum in order to remove the free oxygen contained in the liquid and then a definite amount of oxygen depending on the size and number of the filaments being spun is reintroduced just before the liquid enters the spining vessel. In the apparatus shown, the liquid, after being de-aerated by flashing through a vacuum, flows from a supply pipe 3 by way of a dropping funnel 4 into a sight glass 5 connected at its lower end to a pipe 6 leading to the spinning vessel. The sight glass 5 serves as an air chamber to which air can be admitted by a screw inlet valve 7 having a port 8. Thus by suitable adjustment of this valve 7 and valve 2 which controls the flow of coagulent liquid, the amount of oxygen picked up by the liquid in passing to the spinning vessel can be regulated as desired. The sight glass 5 is mounted in a stirrup 9. which is pivotally secured to the valve casing 1, and is held in position. therein so as to make a tight joint with a packing 10 by means of a supporting shoe 11 adapted to be adjusted by a setscrew 12. In an example of the process, the oxygen content of the coagulant is reduced to a minimum, for example 1.0 c.c. per litre and then the coagulant is allowed to take up a definite amount of oxygen, for example 1.5 c.c. per litre when 150 denier filaments are to be spun. When smaller filaments are to be spun the coagulant is allowed to absorb more oxygen in order to prevent too rapid coagulation of the filaments.

Abstract: 1,037,233. Automatic temperature control. NATIONAL PLASTICS Ltd. May 21,1963 [May 22, 1962], No.19609/62. Heading G3R. [Also in Division F4] The temperature of circulating water, e.g. for heat transfer in a plastics mould, is rapidly brought to an operating range by steam passed through or around it and then kept within the range by a thermostatically controlled electric heater. Should its temperature rise above an upper limit the thermostat operates a valve to replace some of the water from a cool supply. As shown, the water in a tank 1 is initially heated by steam in a jacket 8 and is circulated by a motor driven pump 4. The tank is connected either to cold water mains or a cooler by an inlet 6 and has an outlet 7 in which is a solenoid operated valve 14 controlled by a regulator 12, which also controls the electric heater 11, in response to a temperature sensitive element 13 in the return flow pipe.

Abstract: 1,093,385. Crop-sprayers. W. H. STOUT. May 10, 1965, No. 19654/65. Heading B2F. [Also in Division B7] A mobile irrigation system comprises a conduit 12 provided with a plurality of spaced nozzles 20, said conduit being supported above the ground by means of walking supports 14. Each support includes a pair of substantially vertical legs 30, 32 which are provided with feet 34, 35 and are interconnected by a crank member 58. The upper portions of the legs are mounted on the conduit 12 by a mechanism 36 which is actuated on rotation of the conduit by a chain drive, Fig. 1 (not shown) to produce up-and-down movement of first one and then the other of the legs, coupled with a relative movement of the lower ends of the legs in a direction laterally of the conduit. Each leg 32 is connected to an eccentric portion of the mechanism 36 by a bearing 48 and the eccentric portions of alternate supports are mounted in alignment, Fig. 7 (not shown). Sprinkling may be continued during forward movement of the conduit. In the embodiment of Figs. 8 and 9 (not shown) the legs are interconnected by a pivoted sleeve, and in the embodiment of Fig. 10 (not shown) the feet are connected by crank members. Figs. 11-18 (not shown) depict aluminium supports (110), (112) in the form of a frame having pads (117) beneath their feet. The crank mechanism (130), Figs. 17 and 18, comprises a pair of spaced crank arms (132) joined by cross bars (134). Rotation of a drive shaft (146) and gears (148) results in the rotation of pinions (140) which engage racks (137) in the arms (132). Stop bars (156) connecting the legs of each support prevent the pinions from climbing the curved portions of the racks so that the crank (150) is tilted up and cover, thus moving the supports relative to each other.

Abstract: Polymeric organo-silicon compounds are obtained by hydrolysing compounds of the general formula (RO)3Si(CH2)2SCH2COOR1, wherein R and R1 are the same and are methyl, ethyl or n-propyl radicals, in alkali or acidic solutions e.g. an alcoholic solution of potassium hydroxide forms a potassium salt of the carboxylic and siliconic acid groups which is an oil and yields a water-soluble solid on heating. The addition of a strong acid, e.g. hydrochloric or sulphuric acid, to this water solution yields a gel which may be dried to a hard solid soluble in aqueous alkali.  The addition of carbon dioxide to an aqueous alkaline solution of the potassium salt referred to above causes a gel to form.ALSO:The invention comprises organo-silicon compounds of the formula (RO)3Si(CH2)3SCH2COOR1 wherein R and R1 are the same and are methyl, ethyl or n-propyl radicals, and a process for the preparation of the above compounds by reacting methyl, ethyl or n-propyl thioglycollate with an allyltrialkoxysilane having the same alkyl group, and fractionally distilling the reaction product. In the example, ethyl 3-thia-7 - sila - 7,7,7 - triethoxyheptanoate is prepared. The corresponding methyl and n-propyl compounds are also mentioned.  Alcoholic potassium hydroxide forms a potassium salt of the carboxylic and siliconic acid groups when reacted with compounds of the above general formula.
