Patent GB-783506-A (GB)
Title: Alkali cellulose ageing
IPC: C08B1/08
Filed: 1955-01-13
Abstract: Aged alkali cellulose is made by subjecting a slurry of cellulose in an aqueous alkaline solution containing an emulsifying agent to the action of gaseous oxygen uniformly and stably dispersed as bubbles which, for the most part, may have diameters of less than 120 microns.  Suitably, shredded cellulose is added to 7-30 per cent, preferably 16-20 per cent, sodium hydroxide solution which is at or above a temperature of 50 DEG  C., and stirred for 5-15 minutes so that the final uniform slurry contains 2-6 per cent of cellulose and preferably 3-4 per cent. To this mixture is added 0.1-2.0 per cent, generally 0.5 per cent, of such emulsifying agents as those sold under the Trade names "Prestabit Oil V-New," "Nopco-1179M," "Soromine BSA Paste," "Brij-30," or "Triton-X-100".  Oxygen is dispersed in the mixture by passing an oxygen-containing gas together with the mixture through an agitating or disintegrating device, a number of which are specified, for a duration of passage of less than one second, the temperature being in the range 45-75 DEG  C., and preferably 60-65 DEG  C.  The mixture is then allowed to stand at this temperature, with or without gentle agitation, for a period of 80 minutes or more. The process may be adapted for continuous operation, the slurry which flows through the system being split into batches to ensure that successive batches are aged under substantially the same conditions. After the ageing process the slurry is degassed at low pressure.  The low pressure also causes the liquid to boil, and this boiling is continued until the temperature has fallen to 45 DEG  C.  The slurry is then dewatered in a press, and the resulting alkali cellulose may then be xanthated and dissolved in sodium hydroxide solution to produce viscose. Specifications 783,503, 783,504 and 783,505 are referred to.

Title: Improvements in or relating to liquid damped resilient suspension devices for vehicles
IPC: B60G15/06
Filed: 1942-02-02
Abstract: 554,386. Shock-absorbers. AUTOMOTIVE PRODUCTS CO., Ltd., RIBBESFORD CO., Ltd., ONIONS, J. H., and THORNHILL, P. W. Feb. 2, 1942, No. 1391. [Classes 108 (ii) and 108 (iii)] A liquid damped resilient suspension device for vehicles comprises main and auxiliary resilient members which act in unison on the impact stroke whereas on the recoil stroke the recoil of the auxiliary member is damped out, the recoil of the main member only being effective until return to normal static position is reached. The suspension device is attached by a bracket 18 to the vehicle and the wheel 25 is supported at the end of a cranked arm 23 pivoted about a fixed point 24 and attached at its end to the cylinder 10 of the main resilient member and by an extension 63 to the dashpot piston rod 38 of the auxiliary resilient member 30. The ends of the cylinders 10 and 30 are attached to the bracket 18. The piston rod of the auxiliary device is hollow and receives a hollow upstanding member 44 attached to a perforated fixed obstruction 33 in the cylinder, the apertures in which are adapted to be closed by a spring valve 52. A leak valve 36 is disposed between the head 37 of the piston rod and a projection 40 on the piston rod to have limited longitudinal movement thereon and an auxiliary spring 65 surrounds the piston rod but normally does not press upon the leak valve. A loose pressure piston 47 is also disposed in the cylinder. On impact to the wheel 25, the main spring is compressed and the hollow piston 38 is drawn out to compress the auxiliary resilient member 65 so that liquid from the space 34 passes through apertures in the hollow piston rod through the upstanding member 44 to chamber 46 and thence through the valve 52 to space 35 beneath the piston head, the valve 36 being closed by the auxiliary spring 65. On recoil the valve 52 closes and the liquid in space 35 is trapped so that recoil of the auxiliary resilient member is prevented until the pressure in the chamber 35 is raised by the main spring recoil sufficiently to raise the valve 36 against the action of the auxiliary resilient member 65, thus retarding the recoil of the main suspension spring during return to normal static position. Liquid eventually flows from the space 35 to the space 34 through the leak valve and allows the auxiliary resilient member to resume its uncompressed condition.
