Patent GB-606936-A (GB)
Title: Improvements in and relating to moulding polyvinyl chloride pastes
IPC: C08F259/04
Filed: 1946-01-22
Abstract: Rigid or semi-rigid mouldings are manufactured from a paste of polyvinyl chloride dispersed in a plasticising agent comprising liquids of low volatility which are non-solvents for the polymer at room temperature, but rapidly dissolve it at elevated temperatures. The paste is intimately mixed with one or more easily polymerizable monomeric organic liquids having ethylenic unsaturation which are soluble in the plasticiser used for dispersing the polyvinyl chloride and which polymerize to give rigid products.  The mixture is then moulded under such conditions of temperature, pressure and time as cause complete gelatinisation of the paste and complete polymerization of the monomer.  If desired, a polymerization catalyst, e.g. benzoyl peroxide, may be added prior to moulding. Specified plasticisers are tricresyl phosphate, dicetyl phthalate and di-(ethyl hexyl) phthalate. Methyl methacrylate is the preferred monomeric liquid, and generally the monomer does not exceed 50 per cent of the weight of the paste.  Specification 574,804 is referred to.

Title: Method of production of new artificial silk from seaweed
IPC: D01F9/04
Filed: 1934-01-22
Abstract: Artificial silk is produced from a jelly-like substance containing algin, mannite, proteinous matter and cellulosic matter, prepared from seaweed, by dissolving it in ammoniacal-copper solution containing caustic alkali, and spinning into a bath containing a salt prepared from furfurol and caustic soda, a sulphate, an aliphatic acid, alcohol, and formalin.  The artificial silk is afterwards treated with a mixed solution of a sulphate, aliphatic acid, a sulphite, and alcohol, washed with water, and sized by means of a size prepared by dissolving brown alga in 20 per cent ammonia under 3 atmospheres pressure, filtering through a bed of carbon and diatomite, and adding acetic acid.ALSO:A jelly-like substance containing algin, mannite, proteinous matter and cellulosic matter, prepared from seaweed, is dissolved in an ammoniacal-copper solution containing caustic alkali and spun into a coagulating bath to produce artificial silk.

Title: Improvements in or relating to reflectivity gauges
IPC: G01J1/14
Filed: 1937-01-28
Abstract: 470,230. Measuring reflectivity. GENERAL ELECTRIC CO., Ltd. Jan. 28, 1937, No. 2536. Convention date, Feb. 21, 1936. [Class 97 (i)] A gauge for estimating the reflectivity of a surface comprises a pair of strips 1, 1<1> whose reflectivity varies continuously from one end to the other, located one on each side of a narrow slot 2 so that their parts on opposite sides of any point of the slot are of substantially equal reflectivity. The gauge is placed on the surface 6 to be tested and the whole is illuminated by diffuse light. The uniform surface 6 will appear to have enhanced brightness at the left hand end of the slot, where it is surrounded by a darker surface, and to have diminished brightness at the right-hand end, where it is surrounded by a brighter surface. The slot will thus have the appearance of being graded in brightness from one end to the other, and this appearance facilitates the detection of the point 7 at which the brightness of the slot is the same as that of the gauge strips. A scale 3 is marked on the gauge. If the reflectivities to be measured are those of nearly white bodies, the slot may be covered by a grey filter.

[A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 2, 1938.] [Class 114) In variable-pitch screw propellers in which adjustment is effected by hydraulic motor under the restraint of a spring, the latter is arranged in a chamber containing oil at a pressure higher that that of the surrounding fluid. The propeller 2 has blades 10 with an eccentric pin 14 engaging a guide 13 on a slidable member attached to a piston 6. This slidable member has a control rod 16 which has passages coacting with ports in the slide for supplying pressure to either side of the piston. On the forward side are placed two springs 19, 20 of which the outer spring 20 has an outer diameter such that is in close contact with the wall of the chamber 8. Should the supply of pressure oil fail the piston 6 is forced to the end of the cylinder and the port 40 is closed to retain such oil as surrounds the springs. In this limit position of the piston the nut 22 on the slide rod abuts against a collar 23 on a flange . 21 which forms the front abutment also for the springs. With this arrangement it is possible to unload the springs prior to detaching the cap 8 for dismantling.

[Also in Group XXXIII] A retractable buffer of the type which is maintained in its extended operative position by a toggle D, the toggle being in exactly its fullyopen dead-centre position and having a locking and actuating device E combined therewith, is characterized in that the arresting element 13 of the buffer is one of the cross-members of a frame B connected by links or the like 16, 23 to a fixing stand A in such a manner as to form, when viewed in side elevation, an articulated parallelogram structure, the toggle being connected diagonally between two of the articulation axes. The frame B consists of two tubular elements 10, each containing two slidable threaded rods 11 adjustable longitudinally by nuts 12 and joined by a pair of elements 13, and the toggle comprises a pair of links 27, 28 pivoted together on a pin 29. The toggle is locked and actuated by a lever 32 also pivoted on the pin 29. In the operative position of the buffer (Figs. 1, 5) the toggle is locked between an abutment 31 on the stand A, which engages the link 27, and a pair of fixed abutments 38 carried by members 39, which engage abutments 37 on the lever 32. The lever is urged towards this locking position by a pair of springs 35 connected between lugs 33 on the lever and lugs 36 on the link 27. When it is desired to retract the buffer the lever is rotated about the pin 29 in the direction of arrow f<SP>3</SP>, e.g. by pulling on a cable 42, and as it turns the abutments 37 move out of engagement with the fixed abutments 38 and, after a lost motion, the lugs 33 engage a pair of lugs 34 on the link 27. Thereafter, the lever 32 and link 27 turn together about the pin 24 and the toggle breaks, the buffer then being moved towards its retracted position by a pair of springs 21 which urge the link 16 in the direction of the arrow f<SP>1</SP>. #<SP>1</SP>. The buffer may be employed to retain a load L in an aircraft prior to parachuting, the pull on the cable 42 being caused by an extracting parachute (8ee Group XXXIII).

Preferably at least 80 wt. per cent of the fibres are contained in a spherical shell or annulus space between 0À7R and 1À0R from the centre of the sphere or axis of the cylinder, where R is the radius and is preferably 2À5 to 2À5 mm. In the embodiment of Fig. 6C a continuous filament or continuous multifilament yarn 3 is fed to nozzle 4 and cut as it is effected through outlet 8. The stream of air and fibre passes through tube 9 and the fibres are collected in the hemispherical end of vessel 11 the vessels having perforations through which the air passes thereby compressing the fibres into a body. The gas stream is directed eccentrically of the vessel axis to rotate the fibrous body producing a spere in which the outer layers have been densified by the centrifugal force. To ensure this vessel 11 may be moved horizontally with respect to tube 9 Fig. 6B (not shown). Tube 9 may be removed and air directed on to the fibrous body by a tube (14), Fig. 6D (not shown) aligned at an angle to the axis of vessel 11. In the embodiment of Fig. 8B a cylindrical fibrous body is produced by directing an air stream containing fibres into cone 26 and the fibrous body removed by belts 27, 28. A second pair of belts 29, 30 may be driven at higher speed to draft the body 4 fold. The fibres may be of nylon, polyester, polyacrylate, polyvinyl alcohol, polyvinyl chloride, polymethane or polyvinyl chloride. At least 30 wt. per cent of the fibres may be of a polymer melting at least 30% below the remaining fibres, have a high melting core 1 low melting sheath or comprise low melting staple fibres or powder added to the air stream carrying the long fibres, bonding being produced by heating specified low melting polymers are a copolyester of polybutylene terephthalateisophthalate-odipate, nylon 6, 12, 66 and 6, 10 and copolymers thereof and a copolymer of acrylonitrile and methacrylate. Where the low melting polymer is in the form of fibres it should not shrink more than 10% more than the other fibres at the bonding temperature. Bonding may alternatively be accomplished by spraying the fibrous body with at least 10% of a silicone or an acrylate ester as a liquid emulsion and heating.
