Title: Process for producing synthetic resin article having mar-resistant surface
IPC: C08F18/08
Filed: 1965-09-21
Abstract: 1,117,191. Mar-resistant surfaced articles. MITSUBISHI RAYON CO. Ltd. 21 Sept., 1965 [13 Oct., 1964; 18 March, 1965; 15 July, 1965; 16 July, 1965], No. 40174/65. Heading B5A. Synthetic resin articles, at least part of the surface of which is a mar-resistant layer of polydiethylene glycol bisallylcarbonate (GAC) are produced by polymerizing a monomer containing at least 50% by wt. of methyl methacrylate in intimate contact with the GAC layer. The GAC layer is preferably first polymerized on the inner mould surface in the absence of oxygen, e.g. by covering the polymerizable layer with an air-impermeable film which may be removed (when the film may be a polyester, polyvinyl alcohol which may be removed by dissolution in water, aluminium foil, P.T.F.E. or polypropylene which contains a proportion of stabilizer which does not disturb the polymerization) or retained in position (when the film may be regenerated cellulose, cellulose acetate, nylon or tracing paper). When the film is removed, the GAC layer is preferably treated with an alkaline substance (e.g. caustic soda, caustic potash, calcium hydroxide, barium hydroxide in dilute aqueous solution, or an alcoholic solution of caustic soda or caustic potash, or a mixture of an alcohol of 1-6 carbon atoms per molecule and acetone, benzene, toluene, diethyl ether, dipropyl ether or ethyl acetate) before contact with the methacrylate. A decorative sheet may also be interposed between the two layers.

Abstract: 1,099,230. Transistor amplifier circuits. FERNSEH G.m.b.H. Sept. 9, 1966 [Sept. 10, 1965], No. 40334/66. Heading H3T. In a variable gain amplifier for a video signal an input 8 is fed to the commoned emitters of a pair of PNP transistors 4, 5 and to the commoned emitters of a pair of NPN transistors 2, 3. One of each pair of transistors 2, 4 has its base and collector connected to reference potentials, and the other two 3, 5 have their bases connected to a variable gain control 27 and their collectors connected in parallel to an output terminal 14. The input signal is fed to the commoned emitter circuits via further transistors 1, 6 which have their bases biased by network 17, 18, 19 so as to add equal and opposite D.C. components to the signals fed to the two emitter coupled pairs. Variation of resistor 27 varies the division of currents II, 16 between the pairs 4, 5 and 2, 3 respectively thus varying the gain without changing the means D.C. in the output circuit. Diodes may be included in the coupling of transistors 1 and 6 to their respective emitter coupled pairs.

Filed: 1966-09-14
Abstract: 1,104,307. Universal joints. DANA CORPORATION. 14 Sept., 1966 [24 Sept., 1965], No. 41150/66. Heading F2U. Relates to a constant velocity universal joint of the type in which drive transmitting balls 38, engaging paired axially extending grooves 34, 36 in outer and inner members 10, 24, are retained uniplanar by a cage 40 spherically seated on the inner member. In such a joint, to permit assembly of said inner member 10 into the cage without weakening the cage structure, the axial length of at least one, 37A, of the lobes circumferentially intermediate the grooves 36 of the inner member is less than the axial length of the remaining lobes 37 and less than the circumferential length of at least one, 50A, of the ball receiving and engaging openings in the cage, the circumferential length of the opening 50A being less than the axial length of the remaining lobes 37, so that, when the inner member is presented to the cage, at 90 degrees, the lobe 37A is insertable into the opening 50A. The circumferential length of the cage opening 50A, together with that of the diametrically opposite opening 50B, is greater than that of the remaining openings 50 but is not sufficient for the accommodation of the remaining lobes 37. For balance, the lobe 37B diametrically opposite the lobe 37A may also be shortened. As shown, the outer member is spherically seated on the cage and the balls 38 engage arcuate grooves 34, 36 having respective generating centres C<SP>1</SP>, C<SP>11</SP> equally axially displaced on opposite sides of the common centre C of the spherical seatings of the outer and inner members on the cage. When the inner member has been inserted into the cage and rotated so as to be coaxial therewith, this subassembly is inserted, at 90 degrees, into the outer member. During this insertion, diametrically opposite lobes 35 circumferentially intermediate the grooves 34 of the outer member enter the elongated cage openings 50A, 50B. Finally, the inner member and cage subassembly is rotated so as to be coaxial with the outer member. The outer member may, alternatively, have a cylindrical bore, in which case the inner member and cage sub-assembly may be directly inserted.

Fig. 1 illustrates four embodiments 1, 2, 3, 4. Embodiments 1, 2 show the spring 31, 32 connected to the inner periphery of the brake disc by welding 33 or by bolt joints 34. Embodi; ments 3, 4 show a part of a closed ring which comprises portions provided with holes 41 and the ring is connected to the brake disc at points situated between the holes 41, by means of bolts 42 or by welding 43. The portions of the ring 40 situated between the holes 41 and the connecting points 42, 43 act as resilient elements, whereby each portion 40 between two connecting points may be considered as a bending spring. It is possible to provide a heat insulating layer between the friction surfaces of the disc and the spring elements. In the embodiment of Fig. 2 (not shown) a number of leaf springs (21) are provided around the inner periphery of the disc. The spring(s) may also be situated around the outer periphery of the disc and in this ease a caliper housing surrounds the inner rim of the disc.
