Title: Improvements in or relating to the manufacture of cellulose
IPC: D21C3/02
Filed: 1938-01-29
Abstract: 509,938. Refining cellulosic materials. DREYFUS, H. Jan. 29, 1938, No. 2902. [Class 2 (ii)] Cellulose suitable for conversion into cellulose esters and,ethers and into viscose is produced by treating wood for not more than 5 hours with a 7-10 per cent. aqueous solution of a caustic alkali such as caustic soda at a temperature which, substantially throughout the treatment, lies between 150‹ and 165‹C., the amount of the caustic alkali present during the treatment being between 35 and 50 per cent. of the weight of the wood. Thorough impregnation of the wood by the alkaline liquor may be effected by evacuating the-vessel containing the wood before the alkaline liquor is admitted thereto, or by agitating the wood with the liquor. The wood may be pretreated with an agent, such as water or dilute alkali, adapted to remove resins and the like. The cellulose produced according to the process of the invention may be bleached, for example, with chlorine or hypochlorites, and preferably the bleach, or the last stage of the bleach if more than one stage is employed, is carried out in an alkaline medium. If desired, between the end of the alkaline disintegration and the beginning of the bleach, or between the stages of the bleach if more than one stage is employed, the cellulose may be treated with a cold relatively concentrated alkali, for example, with 12-20 per cent. caustic soda solution. Where the cellulose is to be used in the manufacture of cellulose esters it may be activated by treatment with lower aliphatic acids as described in French Specification 565,654, or with vapours of such acids as described in Specification 263,938, [Class 2 (ii)]. In an example, spruce chips are heated at 155‹C. for about 3 hours with 8 per cent. aqueous caustic soda, the amount of alkali present being 45 per cent. based on the air-dry weight of the wood. The cellulose produced is washed with hot water and bleached first with chlorine in an acid medium and then with hypochlorite in an alkaline medium. Specification 459,790 also is referred to. According to the Provisional Specification, lignocellulosic materials other than wood may be treated and the temperature reed not be kept as high as 150-165‹C. throughout the whole of the alkaline disintegration provided the concluding stages are effected at this temperature.

Title: A device for filleting fish
IPC: A22C25/16
Filed: 1932-02-01
Abstract: 392,668. Filleting fish. BAADER, R., 33, Wakenitzmauer, L³beck, Germany. Feb. 1, 1932, No. 2992. [Class 28 (ii).] The backbones are cut out of decapitated fishes to form fillets by disc knives 1 .. 4 arranged out of the path of movement of the fish, and the fish is pressed yieldingly against the knives so that it accommodates itself, as regards its position, according to the crosssectional size of the backbone at the point of cutting. The fishes are arranged on their sides on a table 10 and the tails are gripped by jaws 9 on an endless chain 7. The pair of knives 1, 2 is arranged in front of the table 10 so that the backbone of the fish rests on the knives at the region of cutting, the accommodating movement of the fish being thus permitted. The fish then rests on fixed tables 11 spaced laterally to permit the passage of the jaws 9. Pivoted extensions 11<1> of the tables 11 are influenced by springs 15 or weights, normally to press the fish upwardly against the undersides of the pair of knives 3, 4 which cut above the backbone similarly to the underneath cut effected by the knives 1, 2. The fish is then opened by spreading members 12 and obliquely arranged knives 5, 6 effect an angular cut beside the prismatic backbone portion adjacent to the belly cavity, the fish being resiliently pressed towards the knives by a member 13. The two filleted pieces are thus cut free from the prismatic portion of the backbone which extends from the head of the fish to the rear of the belly cavity, whereas they remain adhering to the vertebrae of the oval portion of the backbone which extends from the rear end of the belly cavity to the tail fin.

Title: Improvements in or relating to optical couplers
Inventor: TIEN PING KING
IPC: H04B10/43
Filed: 1970-01-22
Abstract: 1287035 Optical couplers WESTERN ELECTRIC CO Inc 22 Jan 1970 [24 Jan 1969 21 April 1969] 3078/70 Heading G2J [Also in Division H3] An optical coupler comprises a thin film 12, 13 of optical material the major surfaces of which are plane parallel and the index of refraction n 2 , and a prism 16 having an index of refraction n 3 , the prism being adapted for internal reflection of light at a first surface 18 disposed parallel to the major surfaces of the thin film 13 and separated therefrom by a gap of refractive index n 1  to partially frustrate the internal reflection, the major surface remote from the gap being in contact with an environment 14 (e.g. a substrate) having a refractive index n 4 , n 3  being larger than the largest of n 4 , and n 1 , and the coupler, when suitably orientated to receive a coherent light beam, providing phase-matched coupling of said beam to a wave propagating in the thin film transverse to the direction of the beam. The prism and the thin film 12 are optically decoupled beyond the region of frustrated internal reflection. The decoupling may be effected by providing the prism with a second surface 21 cut at an obtuse angle to surface 18. The gap of refractive index n 1  may be air or it may be a dielectric material. Where such a material is used the decoupling may be effected by increasing the thickness of the dielectric material. Light propagating in the thin film may be coupled out of the film using either another portion of the said input prism 16 surface, or using a second prism. In one embodiment Fig. 4 (not shown) the coupler also includes a reflector to intercept light which has passed through the prism 16. This forms an optical resonator and causes light to propagate in two directions along the thin film. Two output prisms are used in that embodiment. In another embodiment Fig. 6 the prism 86 receives a plurality of signal coherent light beams 91, 92, 93, at different angles, and phase-match couples them to different waves propagating in thin film 83. These different waves are coupled out by a prism 97. Prisms 86, 97 have multiple faces through different ones of which different beams and waves are coupled. The light propagating in the thin film may be modulated during passage therethrough; the thin film could then be gallium arsenide having its crystalline axis normal to the planes of modulating electrodes and the substrate could be sapphire. Alternatively the thin film may be a semi-conductive junction region, semiconductive material of different types being located on opposite sides of the junction region. The dielectric gap in the coupling or uncoupling region is less than one wavelength of the light waves being propagated. In an amplifier a frequency shifter Fig. 10 signal energy 211 and pump energy 225 are fed to prism 216 and hence waveguide 212. A desired abstracted beam is coupled out by prism 222.
