Patent GB-877225-A (GB)
Title: Vulcanisable rubber-like compositions
Inventor: CLARKSON DEREK LIONEL
IPC: C08L9/02
Filed: 1959-07-17
Abstract: Vulcanizable compositions of 40-65 parts (weight) butadiene-1, 3/acrylonitrile copolymer, correspondingly 60-35 parts polyvinyl chloride, and 5-40 parts ester plasticizer are prepared by mixing the polyvinyl chloride and plasticizer at room temperature to obtain a powdery mixture; fluxing the copolymer on a mill at 70 DEG -100 DEG C.; and blending the powdery mixture into the fluxed copolymer on the mill whilst maintaining the temperature of 70 DEG -100 DEG C. Plasticizers specified are dibutyl phthalate, dioctyl phthalate or sebacate and tritolyl phosphate.  The copolymer preferably contains 20-40 wt. per cent acrylonitrile and may be obtained by an aqueous emulsion process using a polymerization modifier, e.g. lauryl mercaptan.  A heat stabilizer, e.g. calcium stearate, is preferably added to the polyvinyl chloride before milling.  Fillers, vulcanization ingredients and other additives, e.g. pigments, may be added at any time after the polyvinyl chloride has been blended in and the composition shaped and vulcanized, e.g. at 141 DEG C. for 30 minutes.  The vulcanized compositions are particularly useful where ozone and oil resistance is required, e.g. electric cable sheathings, hoses, car window sealing strips and printers' rollers.  In Example (1), a blend of 65 parts butadiene/acrylonitrile (37% nitrile, Mooney viscosity 45), 35 parts emulsion P.V.C. (K value 55), 15 parts dioctyl phthalate and 1,5 parts calcium stearate prepared according to the invention at 80 DEG C. is compared with similar blends wherein (1) the plasticizer is added separately and (2) the mill is maintained at 140 DEG C. after adding 50 parts aluminium silicate and vulcanization in the presence of zinc oxide, stearic acid, dibenzthiazyl disulphide, tetramethyl thiuran monosulphide, sulphur and titanium dioxide.  Example 2 illustrates the vulcanization of a similar composition wherein the plasticizer is tritolyl phosphate and wherein additional plasticizer is included with the vulcanization ingredients.

Title: Permanent magnets for electrical machines
IPC: H01F7/02
Filed: 1976-06-18
Abstract: 1535604 Permanent magnets ROBERT BOSCH GmbH 18 June 1976 [20 June 1975] 25263/76 Heading H1P A segmental permanent magnet for an electrical machine comprises (Fig. 1) a first ferrite material 1 at the ends and a second ferrite material 2 intermediately wherein material 1 has coercive forces I<SP>H</SP>c1 exceeding that of material 2 while its remanence Br 1  is in defect of that of material 2, Br 2 . Consequently a greater resistance to demagnetization occurs at the ends and a greater flux density occurs in the intermediate segment with minimized magnet volume. It is shown by mathematics (Fig. 2, not shown) that where V R  = volume of the high remanence ferrite V Ges  = total volume of the ferrites I<SP>H</SP>c (R) = coercive force of high remanence ferrite H<SP>H</SP>c (K) = coercive force of high coercive ferrite  where only the trailing edge of the magnet relative to a machine rotor is of high coercive magnetic material and V R <SP>1</SP> is the volume of high remanence ferrite it is shown that For example using sintered strontium ferrites of which 1 has I<SP>H</SP>c = 320 k A/m B r  = 350 m T and 2 has I<SP>H</SP>c = 256 k A/m B r  = 380 m T the materials are worked up into pastes with water, pressure moulded with high coercive material at the ends and high remanence material at the segmental arc with a proportion of the high remanence material calculated from equation (1), compressed and drained, magnetically aligned and further pressed. Thereafter they are demagnetized, sintered at 1200-1250‹ C., surface ground to shape, with no visible junction between the elements, and subsequently magnetized. Alternatively the individual elements may be manufactured separately, surface ground, and conjoined. Magnets may be similarly fabricated from plural different ferrite materials aligned in order. The segmental magnets are particularly applicable to permanent magnet D.C. motors, starters, magnetos and exciters.
