Title: Improvements in or relating to the production of cellulose ethers
Inventor: JUNGE EWALD
IPC: C08B11/02
Filed: 1959-04-06
Abstract: Cellulose ethers are made by comminuting cellulose to an average fibre length of less than 1 mm., converting the cellulose into soda cellulose in a reaction vessel by spraying it with a concentrated aqueous solution of sodium hydroxide while it is being stirred, and alkylating the soda cellulose with a gaseous or liquid alkylating agent in the same reaction vessel.  In the example, 1 kg. of cellulose ground to a fibre length of 130 microns is sprayed (while being stirred) with a 50% by weight aqueous solution of caustic soda at 50 DEG C. in an autoclave, the free space in which is occupied by nitrogen.  The soda cellulose thus formed is then heated to 80 DEG C. and subjected to a constant methyl chloride pressure of 3-5 atm. gauge for 1 hour.  The methanol formed is distilled off, the sodium chloride is removed from the crude product and the methyl cellulose is centrifuged and dried.  The process reduces the consumption of caustic soda and alkylating agent.

Filed: 1942-08-19
Abstract: 560,033. Lifting - dogs. ENGLISH STEEL CORPORATION, Ltd., and BROCKLEHURST, R. W. Aug. 19, 1942, No. 11638. [Class 78 (iv)] A lifting dog, grab, &c., of the type comprising relatively moving jaws tending to assume a closed position on being lifted is provided with means whereby the operator can either lock the jaws in an open position and lift and lower them in that position, or can release such lock, solely by manipulation of the lifting tackle. The device consists of two telescoping members 16, 34 pivoted respectively at 18 and 30 to the grab arms 10 which are each fulcrumed at 11 to the side plates 12 of a framework 15. To lugs 19 extending upward from the member 16 is pivoted a pawl 21 biassed downward by a spring 23 acting through a rocker arm 24 bearing on a pin 25 extending forward from the pawl, all these parts being carried by the member 16. The member 34 is of reduced diameter at 32 to form two spaced apart shoulders at 33 and 35, and between these shoulders is located a loose sleeve 36 slidable with friction inside the member 16. The sleeve is shorter than the spacing between the shoulders 33, 35 and a slot 38 is provided in the member 16 to permit the nose of the pawl 21 to enter and abut against the shoulder 33. A flag mounted on an arm fixed on the pivot spindle 26 of therocker 24 comes into view at a window 39 in each plate 12 when the pawl 21 is up, In operation, the grab is lowered till the frame base 15 rests on the load, when, on further forward feeding of the suspension cable, the weight of the arms 10 allows their lower gripping jaws to open and the pawl 21 eventually to fall into engagement with the shoulder 33, this condition being indicated to the operator by the disappearance of the flag. The grab can then be raised in open-jaw configuration, and when it is desired to lift a load it is lowered thereon and the cables slackened till the jaws, in opening still further, cause the sleeve 36 to be dragged along and to raise the pawl nose, this condition being indicated by the reappearance of the flag. On now commencing hauling the sleeve 36 remains stationary, holding up the pawl 21, till the shoulder 33 abuts against it and slides it inward, the pawl nose passing smoothly on to the enlarged main body of the member 34 and allowing the jaws to grip the load. The inner end of the sleeve 36 is bevelled or rounded to prevent its acting as an abutment to the pawl 21. In a modification a second abutment is provided, permitting the actuation of the grab in two stages.

Filed: 1931-12-15
Abstract: 395,414. Spray carburetters. GRACE, C. J., Cleveland House, City Road, London. Dec. 15, 1931, No. 11732/32. Divided application. [Class 7 (iii).] In a carburetter wherein the air valve serves as the throttle valve, the area of the fuel orifice is controlled in accordance with throttle movement, and the proportion of air to fuel is varied by independent means actuated by suction and adapted to control the supply of air through an auxiliary passage. A nozzle tube 8 is surrounded by a shroud 11, fuel flowing between the tube and shroud past filtering grooves 9 and through larger grooves 10 which correspond with air channels 11b, 11d formed respectively in the shroud and in a cap 11c screwed therein. Around the shroud is a sleeve 12 carrying at its lower end a piston 12a the under side of which is in communication through a controlled duct with the mixing chamber in the neighbourhood of the Venturi tube 30. The sleeve 12 is lifted by suction and by the air stream acting upon a flange PVR at the upper end of the sleeve which is ported at 12b, Fig. 7, to expose more or less of the fuel discharge ports. The closed upper end of sleeve 12 is splined at 14a to receive a splined portion of an axial rod 16, the lower end of which is also splined to engage a boss 18a of an arm 18 connected by a link 19, arm 20 and spring 23 to the actuating arm 22 of the air throttle 21. As the throttle is opened, the spring actuates the members 20, 19, 18 so as to rotate the sleeve 12 and open the fuel orifices for about the first third of throttle opening. After that, the sleeve remains stationary and, when the throttle is closed, is returned by engagement of stops 25, 26, Fig. 3, assisted by the spring. The sleeve 12, when raised by suction, serves firstly to uncover, by the port 14, the air channels 11d to admit air, which enters tube 8 at its lower end, over the fuel orifices and secondly, to cut off by its upper edge 12d the fuel outlets 11b. The extent to which the sleeve can be raised by suction is limited by a spring clip 17 on the rod 16 which can be moved by rod 27 and lever 28. The duct leading to the under side of the piston 12a has the effect of producing a time lag before pressure on both sides of the piston becomes equal and, in consequence, a sudden increase of throttle opening is accompanied by a fall of the sleeve 12, and an enrichment of the mixture.

Abstract: 1465586 Time delay FET switch SQUARE D CO 19 March 1974 [26 March 1973] 12105/74 Heading H3T In a timing circuit having a first D.C. source 14, 24, Fig. 1, for charging a capacitor 49 to a predetermined level in a first direction prior to the initiation of a timing period, a circuit 54, 55, 56 connects the capacitor to a second D.C. source 28, 24 for charging the capacitor in an opposite direction and causes the charge on the capacitor to decrease from the predetermined level when the timing period is initiated and a FET 52 is controlled by the charge on the capacitor 49 so as to switch on when the charge on the capacitor is decreased to a second level. As shown an A.C. supply 10, 11 is rectified by a diode 12 to provide a positive voltage supply on line 14 and a negative voltage supply on line 28 with respect to a common line 24. With a switch 16 open transistor 42 is on to charge the capacitor 49 from positive supply 14, 28 and the other transistors 35, 52, 57, 59 and 64 are off so that magnetic coils 31, 32, 71, 72 of reed relays are de-energized. When the switch 16 is closed the A.C. supply is rectified at 18, relay coils 31, 32 are energized, transistor 35 turns on, transistor 42 turns off to stop charging of the capacitor from the positive supply and transistor 59 turns on to energize a LED 60. After a delay time determined by discharge of the capacitor to the negative supply line 28 adjustable by an RC discharge circuit 54, 55, 56 the P channel FET 52 turns on. This turns transistor 57 on and transistor 59 off to de-energize the LED 60 and turn the transistor 64 on so as to energize the relay coils 71, 72 a delay time after closing the button 16. Opening of the switch 16 causes the relay coils 31, 32, 71, 72 to be deenergized and the circuit returns to its initial state. A suppressor 77 protects the circuit from transient voltages of the A.C. supply. In a modification (Fig. 2, not shown) closing the switch (116) causes the capacitor (149) to be charged in its first direction, the FET (152) turns off and the output transistor (164) turns on and the relay coils (131, 132, 171, 172) are energized. On opening the switch the relay coils (131, 132) are de-energized and the LED (160) is energized for the timing period. After the timing period the FET (152) turns on and the output switching transistor (164) turns off to de-energize the relay coils (171, 172).
