Patent GB-1238802-A (GB)
IPC: C08K5/20
Filed: 1969-05-28
Abstract: 1,238,802. Melamine resin moulding powder. STANDARD OIL CO. 28 May, 1969 [13 Aug., 1968], No. 26883/69. Heading C3R. A stain-resistant moulding powder is made by (A) combining a filler with a formaldehydemelamine resinous condensate syrup; (B) drying; (C) adding 0À1-10 wt. per cent of an amide or precursor therefor and homogenizing. The amide is a polyamide or R-CO-NH-R 1 , where R is alkyl or alkylenyl containing # 15 C atoms, and R 1  is H, or hydroxyalkyl or aminoalkyl containing # 3 C atoms. The amide is solid at ambient temperatures. The precursor is a polynitrile. Examples of amides or precursors are oleamide, stearamide, erucamide, palmitamide, behenamide, N - methylol stearamide, N - ethylol behenamide, N - methylamino stearamide, N - ethylamino oleamide, nylon 66, 6 or 4, polyacrylonitrile, or polymethacrylonitrile. (C) May be performed in a ball-mill e.g. at 32-120 F. and at pressure from atmospheric to 25 p.s.i. Moulding may be performed at 250-375 F. and 1400-4000 p.s.i. The filler may be clay, or fibrous, e.g. asbestos, paper, or alpha cellulose; 20-70 parts filler per 100 parts resin may be used. Step (B) may be performed in hot air at 180-210 F. yielding coarse " popcorn " granules. These are reduced in size, and curing catalysts, mould-release agents, pigments and brighteners may be added; exemplified additives are phthalic anhydride, Zn stearate, rutile TiO 2 . Step (C) is now performed. The melamine-formaldehyde resin is made by reacting 37% aqueous HCHO with melamine in 1: 1 to 3: 1 mole ratio, adjusting to pH 8-6, and refluxing. It is believed that the amide reacts with the resin by surface polymerization, thus modifying the resin surface so that it becomes stain-resistant. Contrasting examples describe the use of acetamide, benzamide and acrylamide instead of the above amide.

Wrapped rod-like articles such as cigarettes are tested for leaks in the wrapping by passing the articles 4 successively endwise through a test chamber 1 having an inlet 2 and an outlet 3 for the articles 4 and which communicates with means tending to maintain the air pressure in the chamber 1 different from atmospheric, e.g. via a port 7, and at a moment during its travel when an article 4 obturates in the inlet 2 and outlet 3 simultaneously and at the same moment at least one of the ends of the article 4 communicates with atmosphere, the air pressure in the chamber 1 is detected to indicate air flow through the article wrapping between the interior thereof and the test chamber. Preferably the pressure maintained in the chamber 1 is less than atmospheric pressure.

Abstract: 1,266,254. Turbines. GENERAL MOTORS CORP. March 12, 1970 [July 25, 1969], No. 11951/70. Heading FIT. A variable area stator vane assembly, e.g. for a gas turbine, comprises non-adjustable stator vanes 10 secured between outer and inner annular shroud rings 7, 8 and adjustable throttling members 42 disposed between adjacent vanes 10. Each member 42 has radial extensions 46, the radially inner of which is secured to a crank arm 47 fixed to a shaft 48 which extends through a reinforcing spine 32 within an adjacent vane 10 The radially outer extension 46 is attached to an actuating arm 50 which is also secured to shaft 48. All the arms 50 are coupled to a unison ring 51, rotation of which causes rotation of shafts 48 with consequential movement of extensions 46 and members 42 in a generally upstream or downstream direction so as to vary the effective flow area between vanes 10. Each member 42 may be rotatable relative to extensions 46, e.g. so that it can automatically align itself with the flow therepast. The inner shroud ring 8 includes upstream and downstream flanged rings 18, 19 bolted to a combustion chamber wall 20 and porous facing rings 22, 23 secured to the rings 18, 19 by spring clips 24. Similar porous facing rings 12, 14 form part of the outer shroud ring 7. Cooling air is introduced behind the porous facings through holes 61, 62, some exhausting through the facings into the working fluid and the remainder flowing into the interiors of vanes 10, the walls of which may also be porous. In a modification, Fig. 6 (not shown), shafts 48 and cranks 47 are eliminated and the movement of each throttling member 42 is a swinging movement about a fixed pivot (57) on the inner shroud ring 8.

Abstract: 1295287 Making piston rings SHEEPBRIDGE STOKES Ltd and G E H HALL 1 July 1970 [7 July 1969] 34075/69 Heading B3A A method of producing piston rings comprises heating an uninterrupted annular element and forcing it on to a shaped mandrel 28 to cause the element to assume a required shape and then cutting a gap in the shaped annular element. A centrifugally cast tube is sliced normal to its axis to form a plurality of annular elements which are placed over the end of a leader sleeve 30. A ram 33 is activated to-push a sleeve 35 over the leader sleeve 30 so as to push the rings along the leader sleeve into a furnace maintained at a temperature of about 630‹ C. The sleeve 35 is retracted and the process repeated so that the leading rings pass over a tapered lead-on portion 29 on to the mandrel 28. When the shaped rings are pushed from the mandrel a cutting tool (not shown) broaches a notch across the inner face of the rings after which the rings are pushed along a rod 22. Jaws 18 of an assembly 15 are retracted by rams 17 to allow the rings to pass the assembly whilst leaving the rod 22 supported by a similar assembly 14. When a number of rings have passed the assembly 15, the rams 17 move the clamps 18 into engagement with the rings on the rod 22, thus holding the rod while the jaws 18 of assembly 14 are released. An end spacer tube can then be removed and the shaped notched rings removed from the rod 22 for further processing and for cutting a gap.
