Title: Improvements in or relating to pigmented compositions comprising low molecular weight polyamides
Inventor: CARTER JOHN ANTHONY
IPC: C08J3/20
Filed: 1960-03-29
Abstract: A pigmented composition, suitable for use in pigmenting high molecular weight linear polyamides, is prepared by forming an aqueous solution of a partially polymerized polymethylene diammonium salt of an aliphatic a -o dicarboxylic acid (see Group IV(a)), mixing the so-formed prepolymer with a pigment and milling, e.g. in a colloid or ball mill.  The salts employed have 8 to 24 carbon atoms and hexamethylene diammonium adipate, octamethylene diammonium adipate, decamethylene diammonium adipate, dodecamethylene diammonium adipate, hexamethylene diammonium sebacate and pentamethylene diammonium sebacate are referred to.  Specified pigments are anatase, carbon black, ferric oxide, lead carbonate and barium sulphate.ALSO:A prepolymer solution of a partially polymerized polymethylene diammonium salt of an aliphatic a -o -dicarboxylic acid is prepared by passing the salt at polymerizing temperature and sufficient pressure to prevent steam evolution through a pressure tube until a degree of polymerization of 1,15-1,37 is reached, cooling if desired, allowing the steam to flash off adiabatically by passing the product through a jet or valve, and if necessary removing further water, to produce a prepolymer solution having a Redwood viscosity of at least 90 secs. at 20 DEG C. Thereafter a pigment is mixed with the prepolymer and milled to provide a composition for pigmenting high molecular weight linear polyamides.  Specified salts have 8-24 carbon atoms and are hexamethylene diammonium adipate, octamethylene diammonium adipate, decamethylene diammonium adipate, dodecamethylene diammonium adipate, hexamethylene diammonium sebacate and pentamethylene diammonium sebacate.  Specified pigments are anatase, carbon black, ferric oxide, lead carbonate and barium sulphate.  In examples a 60% aq. solution of hexamethylene diammonium adipamide was passed at 260 DEG C. and 950 p.s.i.g. through a stainless steel tube with a retention time of 0,9 mins. to form a prepolymer solution containing 38% water and having a Redwood viscosity of 1000 secs. Approximately equal parts of this solution and of water were then mixed with 1/10 th the combined weight of pigment and ball-milled to form a stable pigmented dispersion.  Example 1 describes the admission of the dispersion to an autoclave in which the same salt is being fully polymerized to polyhexamethylene adipamide.

Abstract: 558,401. Protractors &c. HUGHES & SON, Ltd., EVERITT, P. F., and HUGHES, A. J.. Aug. 17, 1942, No. 11527. [Class 97 (iii)] [Also in Group XXIV] A parallel motion linkwork coupling a chart rule with the driving spindle of trigonometrical computing devices such as apparatus for solving triangles, consists in means for accurately transmitting rotatory movement of the chart rule as angular movement to the spindle. The spindle is indicated at a and the chart rule, which is moved over the surface c, at b. The rule is mounted on a free carrier d in the form of a disc somewhat similar to the flange e on the spindle a. The carrier d is connected by three pivots h to three links g, and the flange e by pivots l to three links k, the pivots h, l being equiangularly spaced and at the same distance from the centre of motion of d and e. The other ends of the links are connected to a junction element m by pivots n, o which are also equiangularly spaced and located at a distance from the centre of element m equal to the distance of the pivots h, l from the centres of d and e. Thus there are two sets of at least three angularly related closed kinematic chains, but the number in a set need not be limited to three which is the minimum possible, nor need the number of chains in one set be equal to the number in the other, provided that three or more are provided in each set. The kinematic chains need not be equiangularly related provided that the angular arrangement of the link pivots say h on the carrier d is the same as that on the junction element m. To permit greater freedom of movement, the links g, k may be staggered as in Fig. 2; a carriage may support the element m. The chart rule b is frictionally pivoted about the centre of the carrier d so that it can be turned without rotating the spindle a.

Abstract: 898,358. Aircraft. AVRO AIRCRAFT Ltd. April 19, 1955 [April 20, 1954], No. 11581/54. Class 4. An aircraft comprises a structure similar to that described in Specification 892,491 and of lenticular form sheathed by aerofoil surfaces 10, 11, a radial-flow gas turbine engine within the structure, and means to alter selectively the direction of flow from the engine to provide a propulsive thrust. The engine comprises an intake 19, a compressor 21, an annularly disposed combustion system 22, fuel tanks 23 and a turbine 24. The outlet 25 from the turbine passes to an annular orifice between the periphery of the upper skin 10 and a hollow bead 28, the major thrust being downwards over the bead by employing the Coanda effect. Part of the gases can be emitted at 57 under the control of rudder pedals 61 when the craft is airborne, to produce forward motions but the craft is controlled mainly by upsetting the Coanda effect on selected sectors of the bead 28 with compressed air tapped from the compressor and fed to four selected groups of holes 33 in this bead by movement of a control handle 47, actuating valves 39, 40, 41, 42. A small by-pass 54, around valve 39, can be opened to produce initial forward motion. The aircraft takes off vertically by creating a " ground cushion " which supports the aircraft up to a distance of half its diameter from the ground although its total weight is much in excess of the static thrust developed. Specification 456,063 also is referred to.
