Title: Improvements in or relating to the manufacture of artificial filaments, films, sheets and like shaped products
IPC: D01F2/08
Filed: 1935-11-05
Abstract: Artificial filaments, fibres, films, and like shaped products are obtained from aqueous cellulose solutions to which are added in a form soluble therein synthetic resin components, excluding sulphur derivatives and colloids, and after the filaments or other materials have been formed by extrusion or other shaping process, they are treated to convert the added substances into insoluble or difficultly soluble form by condensation, interaction, polymerization, or like procedure.  The cellulose solution may be viscose or a cuprammonium cellulose solution.  If desired, the synthetic resin components may be added in a partially condensed or polymerized state. Phenol-formaldehyde, and urea-formaldehyde mixtures or partial reaction compounds are specified.  The synthetic resin components may be added at any stage in the preparation of the spinning solution and before the latter is extruded through spinning nozzles.  The subsequent process of hardening may be carried out continuously with the production of the filaments, staple fibre, or films, by intercalation with the other treatments to which the material is subjected.  In an example, about 1--6 per cent of a soluble polymerization product of phenol and formaldehyde obtained in presence of aqueous ammonia is mixed with an aqueous cellulose spinning solution such as viscose.  The filaments or other products obtained are subjected to known hardening treatment such as heating for several hours to 130 DEG  C.  In another example, an alkaline solution of a pre-condensed urea-formaldehyde mixture is added to cellulose xanthate at the dissolving stage.  The viscose is filtered, deaerated, and spun in ripened or unripened condition into a sulphuric acid and sodium sulphate bath.  The urea - formaldehyde gradually hardens in the acid solution, and a separate treatment is unnecessary.

Filed: 1937-11-12
Abstract: 505,580. Vacuum distillation; utilizing vapours for further evaporation. PHIPPS, J. W. and BRITISH DRUG HOUSES, Ltd. Nov. 12, 1937, No. 31161. [Class 32] In vacuum distillation the vapours are condensed in contact with the wall of a condenser filled with a liquid refrigerant maintained at its boiling point, the vapours and the refrigerant flowing over the surfaces so as to prevent freezing of the condensed vapour. 'The cooling liquid may be ammonia, methyl chloride, ethyl chloride, sulphur dioxide, dichloro-difluoromethane, or water. As shown, liquid is evaporated in a vessel 11 under a vacuum maintained by a pump 19. The vapours pass through a liquid trap 16 to a condenser 12 cooled by a refrigerant boiling in the tubes 21, the condensed vapours being removed through the chambers 20, 23, without destroying the vacuum. The vaporized refrigerant passes through a separator 17 to a compressor 13 and condenser 14 and thence as liquid through a trap 15 and the separator 17 back to the tubes 21 of the condenser 12. A spring-loaded valve 22 returns liquid refrigerant to the condenser 14 if the pressure in the tube 21 becomes too high. In modifications, some of the tubes of the condenser 12 are placed underneath a baffle in the lower part of the condenser chamber near the exit for uncondensed gases, to ensure that these latter are cooled substantially to the temperature of the entering refrigerant ; baffles are provided to ensure flow of the vapours over the tubes ; the condenser 12 is constructed of vertical thimble tubes dipping into the condensed liquid. The temperature of the ovaporated refrigerant may be controlled by a thermostat, or the speed of the compressor 13 may be controlled by variations of pressure in the evaporator.

Abstract: 830,739. Washing-machines. MASCHINENFABRIK P. PFENNINGSBERG G.m.b.H. Oct. 1, 1958 [Oct. 11, 1957], No. 31369/58. Class 138 (2). In a two-stage process for an automatic washing-machine comprising a perforated drum 3 rotating about a horizontal axis 2 in a container 1, a continuous supply and discharge of water takes place via inlet 5 and overflow outlet 7 during the first washing stage when heating is effected by heaters 9, while in the second stage the water supply and discharge is discontinued and the heating input is either maintained constant until the end of the process so that the temperature of the washing liquid increases, or it is reduced to maintain the temperature constant. The volume of water supplied is between 0.08 and 0.15 litres per minute per kgm. of dry material washed and the water may be preheated before entering the container. The change over from the first stage to the second stage is automatically effected by regulating valve 10 through control means which respond either to the fixed time interval necessary to attain the required temperature in the first stage, or to the total amount of water supplied. In one embodiment, the first stage is completed when the temperature of the liquid reaches 60- 65 C., the temperature rising to 90-95 C. with a constant heat input during the second stage. In a second embodiment for articles heavily soiled with oil the heating input for the first stage is increased so that a temperature of 90-95 C. is reached, the heating being reduced during the second stage to maintain a constant temperature. The washing-machine may operate with a normal washing process and with either of these two-stage processes.

Abstract: 520,890. Projectiles; air-mines. BICKEL, E. Oct. 31, 1938, No. 31416. [Classes 9 (i) and 9 (ii)]  Projectiles designed to lay a system of airmines in the path of hostile aircraft comprise a number of such mines adapted to be released, in one construction, simultaneously, or in a second construction, serially. An air-mine comprises a bomb connected by a long wire to a parachute. In the first form, Fig. 1, the mines c are packed around a central stem p, the bombs e being conical bodies on which the wire k is coiled. The parachutes o are packed in expansible capsules f tied to the end of the wire coil by windings of fuze-cord v. The time fuze a fires an ignition train n in the stem b, which ignites a charge i and causes the projectile base and jacket d to be rejected rearwardly, thus releasing the air-mines, which are thrown off laterally by centrifugal force. The fuze-train n also ignites the fuze-cords v through ports q. The cords burn out and so release the capsules f, which expand and fall away, so freeing the parachutes. In the second form, Fig. 3, four air-mines are arranged in superposed order on the central stem v of the projectile. The mines comprise bombs s<SP>1</SP> - s<SP>4</SP>, wire coils t<SP>1</SP> - t<SP>4</SP>, and parachutes u<SP>1</SP> - u<SP>4</SP>. The bomb s<SP>4</SP> comprises the projectile head b and the stem v. The parachutes are folded into pans w<SP>1</SP> - w<SP>4</SP>.
