Patent GB-468993-A (GB)
Title: Preparation of cellulose xanthate solutions
IPC: D01F2/08
Filed: 1936-07-24
Abstract: Cellulose xanthate solution is made by a single stage process in which cellulose of solution viscosity less than 1 C.G.S. unit, water, caustic soda, and carbon disulphide are interacted at a temperature of 15--20 DEG  C. in such proportions as to yield a viscose containing from 6--10 per cent each of cellulose and caustic soda. The fibre and the caustic soda solution may be mixed before the addition of the carbon disulphide.  The cellulose of low solution viscosity may be obtained by pretreating wood with hot dilute mineral acid solution prior to extraction by means of alkaline liquor, or by after-treating wood pulp by means of a mercerizing liquor containing an oxidant, followed by a bleaching treatment.  Preferably the low viscosity cellulose has an alpha cellulose content of at least 93 per cent.  The xanthation may be carried out with such an amount of caustic soda solution as to yield a mixture containing about 9 per cent of caustic soda based on all the ingredients.  The xanthate obtained is then diluted, preferably while still in the mixer.  A method for determining solution viscosity is described.

Filed: 1928-07-19
Abstract: 320,667. Rose, A. G., and Rose Bros. (Gainsborough), Ltd. July 19, 1928. Packeting by wrapping-up.-In a wrapping or labelling machine of the kind comprising a pocket wheel each pocket in which receives an article with a wrapper &c. partially folded about it, means being provided for applying adhesive to the inner face of a projecting portion of the wrapper and closing it against another projecting portion, the gum bar and associated pressure bar are of corrugated form with the ridges of one registering with the depressions in the other so that in the absence of a wrapper no gum will be transferred to the pressure bar. The pocket wheel 10, Fig. 1, is intermittently rotated, and the pocket or mould box 11 is charged with a wrapper 14 enclosing the material to be wrapped. On arrival at the station shown, the longer projecting portion 18 of the wrapper is folded down by a top-folder 19 operated in a known manner. The leading side 12 of the pocket is moved away and a tucking-finger 22 tucks in the front edge of the portion 18. The tucking-finger is carried on an arm 29 which also carries a pivoted gum bar 31 pressed forward by a spring 32. As the arm 29 is reciprocated the gum bar contacts with a roller 24 mounted in a gum bath 23, the upward stroke of the gum bar being rendered idle by the engagement therewith of cams 33 on the shaft of the gumming roller. The gumming roller is fitted with an adjustable scraper 27 to regulate the gum supply. On its downward stroke the gum bar picks up a supply of gum from the roller and passes behind the projecting portion 17 of the wrapper which is pressed into contact therewith by a pressure bar 37 resiliently and pivotally mounted on a lever 36. As the lever 29, together with the tucking-finger 22 and gum bar 31 move upwards again, the end of the wrapper portion 17 is smeared with gum, the side 12 of the pocket closes, and the end 17 of the wrapper is folded down on top of the previously folded end 18 by the lower edge 42 of the pressure bar. The corresponding faces of the gum bar 31 and pressure bar 37 are serrated with alternate raised bands and depressions which as shown in Fig. 4, are of such dimensions that in the absence of a wrapper &c. gum is not transferred from the gum bar to the pressure bar.

Title: Improvements in the driving mechanism of lace and other machines
IPC: D04C3/00
Filed: 1919-08-28
Abstract: 154,338. Jardine, Sir E., and Watchorn, E. Aug. 28, 1919. Lace machines and apparatus.-Epicyclic reducing-gear applied to a lace or other heavy machine to afford facilities for starting slowly and for turning at. a slow rate when it is desired to stop it in a particular position, consists of a wheel A loosely mounted on the main driving-shaft C and having one tooth less than an adjacent wheel B which is keyed to the shaft C. When fast and loose pulleys are employed, the loose pulley D is mounted so as to enclose the wheels A, B, which both gear with a pinion F carried on a pin E. The wheel A is connected by means of a sleeve to a ratchet disk G which can be prevented from turning in the reverse direction to the shaft C by depressing a pedal K carrying a detent H. The arrangement of the co-acting ratchet and detent surfaces is such that pressure on the pedal K does not prevent movement of the disk G in the same direction as a shaft C. When the pedal K is released the detent H is forced out of engagement by either the forward or reverse movement of the disk G. When the detent H is engaging the disk G and the bell is on the pulley D, the effect of the pinion E carried round thereby is to impart a slow forward movement to the shaft C.

Title: Improvements in and relating to manufacture of sodium carbonate
IPC: C01D7/40
Filed: 1923-08-21
Abstract: Anhydrous sodium carbonate in a bulky condition is obtained by heating the double salt Na2CO3.3NaHCO3, which may be obtained as described in Specification 202,678 by heating the crude bicarbonate produced by the ammonia-soda process.  The production of the double salt and its subsequent decomposition may be carried out in the same apparatus continuously, for example in a closed receptacle having a plurality of temperature zones through which the material is transported by a suitable conveyor. The first zone is kept at a temperature of 90 DEG -100 DEG  C. care being taken to secure the formation of spicular crystals by preventing premature loss of carbon dioxide and water.  The second zone is maintained at 130 DEG -150 DEG C. until the decomposition of the double salt is complete, the ammonia and carbon dioxide evolved being recovered.  Alternatively, the decomposition may be stopped before the normal carbonate is entirely produced.
