Title: Improved processes for treating seaweed for manufacturing purposes
IPC: C08B37/12
Filed: 1935-03-04
Abstract: Plastic compositions, coating compositions and moulding powders are prepared from treated seaweed and a binder such as latex, glue, gum, resin or oil.  The seaweed is prepared by washing in fresh water, boiling, with stirring, in a solution of sodium carbonate and borax for about three hours and then while continuing the boiling and stirring, adding at intervals of about an hour, colouring matter, sulphide of soda and formaldehyde together with a tanning agent, e.g. wattle bark.  After the last addition the boiling is continued for about an hour and the mass may be dried.  In a modification, the seaweed after being washed, is mashed or pulped to a jelly before being boiled.  To form a plastic composition, latex, liquid glue, gum or resin is added to the treated pulp, the mixture being dried to a plastic state and rolled or moulded.  When latex is used the articles may be vulcanized.  Sheets of the composition may be ornamented by applying preserved seaweed in any desired pattern to the surface previously coated with an adhesive.  Moulding powders are produced by drying and powdering the mix of treated seaweed and binder.  A paint may be prepared by drying the prepared seaweed, grinding to a fine powder, adding latex, vulcanizing ingredients and colour to form a mix of paint-like consistency, rolling out to sheets as thin as paper, soaking in a solvent, e.g. coal tar, naphtha, &c., placing in a paint or solution machine, and thinning with further solvent.  Thin sheets of the material may be cemented together to form ply sheets. Blocks or tiles for floors may be made in two layers, the under one only partly vulcanized.  Diatomaceous earth or other earths or clays may be added in the proportion of about 40 parts of diatomaceous earth to 60 parts of treated seaweed. Specification 371,811 is referred to.

Abstract: 949, 980. Yarns and threads; spinning yarns. NOVIVLAS N. V. Feb.24, 1961 [Feb. 26, 1960], No. 6798/61. Headings D1D,D1F and D1W. A bast fibre yarn is twisted using a twist factor which is on the average along the yarn smaller than 1. 4 and the individual fibres of which are bound together by the natural adhesives which remain in the bast fibres during the manufacture of the yarn. A wet roving of bast fibres is passed through a drafting frame and the yarn obtained is dried and collected. Preferably it is dried when in a package. The yarn may be produced from netted bast fibres. The wet roving may be obtained by chemically decomposing bast fibre stalks as described in Specification 763, 716. A roving 1 passes through drafting rollers 2, 3, passes to a false-twisting device 5 to condense the fibres and the yarn is collected by a spinning pot 7 driven by a belt 8. In one form the device 5 comprises a ring 10, Fig. 2, the inner surface of which has the form of a hyperboloid of revolution. The ring 10 is mounted on a stationary ring 11 and is driven by a band 13. In a modification the device 5 comprises a vortex chamber 14, Fig. 3, placed on the spinning funnel 6 of the pot 7. The funnel 6 has two diametrically opposed recesses 15. Compressed air passes through an inlet 18 into a chamber 19, through oblique channels 20 into a tube 17 in which a vigorous whirl is produced.

Abstract: 697,285. Centrifugal compressors; gas turbine plant DE HAVILLAND ENGINE CO., Ltd., HALFORD, F. B., and COCKBURN, D. M., June 18, 1951 [March 20, 1950], No. 6827/50. Classes 110(i) and 110(iii). In a centrifugal compressor, pre-whirl ahead of the centrifugal impeller is imparted by an axialflow rotor arranged coaxially with and appreciably displaced from the impeller eye and driven in the same direction as but at a lower speed than the impeller, the ring of rotor blades having a mean diameter appreciably greater than that of the eye and extending across an annular entry passage of which the diameter progressively diminishes towards the eye. In the compressor shown in Fig. 1, forming part of a gas turbine plant, the pre-whirl rotor F is carried by a shaft K which is driven through epicyclic gearing L by shaft J connected to the centrifugal impeller C, so as to rotate at about half the speed of the impeller. A part G<SP>4</SP> of the inner wall of the annular entry passage is attached to the rotor F so as to rotate therewith, but may instead be free to rotate under the rotational drag of the air, which preferably flows in a substantially free vortex in this region. The distance between the point D<SP>1</SP> and the entry to the eye of the impeller may be equal to ¢ to ¥ of the diameter of the eye. The entry edges C<SP>5</SP> of the impeller blades may be rearwardly inclined as shown and/or curved forwardly in the direction of rotation. In an alternative construction, the impeller C is driven by the first stage rotor of the gas turbine, while the rotor F is driven by the second stage rotor. The driving shaft of the rotor F passes through the hollow driving shaft of the impeller C. Specification 628,052 is referred to.

Title: An improved process for obtaining the flesh of crustaceans, particularly shrimps
IPC: A23J1/04
Filed: 1940-04-16
Abstract: 538,468. Dressing fish; food preparations. HENNING, W. April 16, 1940, Nos. 6830 and 6831. Convention dates, Nov. 12, 1938 and March 4, 1939. [Class 28 (ii) and 49] Shrimps or other crustaceans are boiled in salt water, deprived of part of their water content so that the flesh shrinks away from the shell &c. and triturated. The shell &c. is then separated from the flesh by screening. The deprivation of water may be effected by heating, storing in salt or other waterabsorbing dry substance, or boiling in a concentrated salt solution. Before trituration the crustaceans may be centrifuged to remove adherent water, and frozen to facilitate trituration. The flesh product may be swelled in water to restore its fresh appearance; to the water may be added flavouring matter. The Specification as open to inspection under Sect. 91 states that the trituration may be performed in a revolving screen of the type used for cleaning berries, that the deprivation of water may be effected by centifuging alone or freezing alone, and that the flavouring matter may be meat juices, meat extracts or spices. This subject-matter does not appear in the Specification as accepted.

Abstract: 374,448. Protective cut-out systems : voltage measuring arrangements. JOHNSON & PHILLIPS, Ltd., Victoria Works, Charlton, and STIGANT, S. A., 41, Crantock Road, Catford, both in London. March 9, 1931, No. 7306. [Class 38 (v).] A three-phase system is protected, in the event of fault, by segregating the negative phase-sequence voltage component by means of a transformer consisting of one three-phase primary and three-phase secondaries, the six phase windings of two of the three-phase secondaries being isolated from one another and having polarities opposite to those of the first secondary winding. As shown in the Figure, the secondaries are A B C, A<1>, B<1> C<1>, and A<11> B<11> C<11> of which the number of turns of the last two is twice that of the first, and their polarities are reversed in relation to the first. The primary is not shown. Phases A<1> B<1> C<1> are shunted by a resistance r<1> and a capacity c<1> in series, the junctions being t<1>, t<3>, t<5>; phases A<11> B<11> C<11> are shunted by a resistance r<2> and inductance l<2>, the junctions being t<2>, t<4>, t<6>. The junctions t<2>, t<4>, t<6> are connected through the protective overvoltage relays RA, RB, RC to earth ; t<1>, t<3>, t<5> are connected to C<11>, A<11>, B" respectively. The ends of the secondary windings A, B, C are connected to B<1>, A<1>, C<1>. The arrangement described isolates the negative phase-sequence component which alone affects the relays. The arrangement may also be used for measuring the negative phase-sequence component of voltages-by replacing the relays by voltmeters. Instead of using a special fourwinding potential transformer three standard two-winding three-phase transformers may be used.

Abstract: 609,263. Snap fasteners. FERNBERG, E. B., and FERNTOL PATENTS, Ltd. March 9, 1946, No. 7420. [Class 44] A snap fastener comprises a stud member 10 (Fig. 1) of flat spring steel bent at 11, 12 and 13 to diamond form, the ends of the limbs 14 and 15 being bent inwards to form feet 16 and 17 which pass through slots 19, 20 in a washer 18 (Fig. 4) and almost touch underneath the central portion 25 of the washer, their abutment constituting a stop member when the fastener is forced into an aperture smaller in diameter than the distance between the points 12 and 13. A button-shaped head 22 is clinched around the frusto-conical rim 21 of the washer. The feet 16, 17 may be shortened so that when the stud is pinched, the lower ends of the limbs 14, 15 abut against the edges 23, 24 of the washer, which in this case constitutes the stop member. In an alternative construction the centre 25 of the washer may be formed as concave depression beneath which the feet of the stud are correspondingly curved, so that provided the width of the material of the stud 10 is less than that of the slots 19 and 20, the stud can move in a solid angle with respect to its head. The fastener may be used to secure a board to a panel, the board being secured around the stud close to its head. The angular play of the stud enables the fastener to accommodate any lack of registration between the fastener and the hole in the panel to which it is applied. As shown in Fig. 5, the stud is formed with out-turned feet 30, 31 engaged in a circular or rectangular aperture 32 in the washer 33, a separate spring stop-member 37 being provided. An upright U-shaped spring member may be used in place of any of the stop-members described above, the arms being bent to increase or decrease the tension of the stud 10. According to the Provisional Specification the stop member may be formed integrally with the washer by turning up the material from the radial slots to form a V. Alternatively, the washer may have two segments cut away in place of slots.
