Abstract: 1,171,713. Vehicle suspensions. FORD MOTOR CO. Ltd. 27 Feb., 1967, No. 9120/67. Addition to 1,145,346. Heading B7D. In a vehicle suspension in which the longitudinal torsion bar springs 32, 47 of the front and rear suspensions on each side of the vehicle are coupled to, and aot in opposition to one another on, an intermediate member 53 which is resiliently mounted on the sprung mass of the vehicle, each torsion bar is supported by and extends beyond the intermediate member and has an integral arm 58 which abuts the other torsion bar. The intermediate member 53 is of boxsection with slots 57 at its ends for the torsion bars and is mounted to the sprung mass by rubber springs 55, 56. The stiffness of the springs 55, 56 determines the degree of interaction between the torsion bars.

The pivot axes of the arms 21 may be inclined to the horizontal. The rear axle 41 is located by two trailing arms 42 and a torque tube extension 45 which is connected to the sprung mass by an offset resilient mounting 46. Lateral compliance of the rear axle is permitted by resilient mountings 49 for the rear torsion bar springs 47 on a subframe 12 which is resiliently mounted on the sprung mass.

Title: Graft copolymers of alkyl ª -substituted acroleins and reaction products thereof
IPC: C08F8/44
Filed: 1960-03-15
Abstract: The swelling of bentonite particles is retarded by coating them with the product obtained by treating with sodium hydroxide a graft copolymer of an alkyl substituted acrolein and an organic polymeric material (in the form of an aqueous dispersion) of at least one monomer having one or two ethylenically unsaturated bonds and being free of reactive hydroxyl groups, e.g. polyvinyl chloride and butadienestyrene copolymers.ALSO:Graft copolymers are made by mixing and graft copolymerizing (A) at least one alkyl alpha-substituted acrolein monomer with (B) an aqueous dispersion of an organic polymeric material of at least one monomer having one or two ethylenic bonds and being free of reactive hydroxyl groups, in admixture with (C) a free radical initiator.  Monomers (A) specified are methacrolein and ethacrolein, which may be used in admixture with other monomers, e.g. butadiene, isoprene, chloroprene, cyanoprene, dimethyl butadiene, styrene, acrylonitrile and methyl isopropenyl ketone. Polymers (B) specified are polyvinyl chloride, copolymers of vinyl chloride and vinyl acetate, polydiolefines and copolymers of butadiene or dimethyl butadiene with styrene, substituted styrenes or an ester or nitrile of acrylic or methacrylic acid.  Initiators (C) specified are potassium persulphate, hydrogen peroxide, benzoyl peroxide and air.  The resulting graft copolymer latices may be reacted with a strong base, e.g. an alkali metal hydroxide, diisopropylamine, diisobutylamine or piperidine, whereby the aldehyde groups of the grafted monomer are converted to methylol and carboxyl salt groups.  The said carboxyl salt groups may be converted to the free acid form by treatment with acetic acid, and the ammonium salt of the copolymer may then be obtained by treatment with ammonium hydroxide.  Films made from the graft copolymer in the free acid or ammonium salt form are rendered hydrophobic by heating.

IPC: H03D3/00

Abstract: 351,420. Wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.- (Assignees of Ranger, R. H. ; 574, Parker Street, Newark, New Jersey, U.S.A.) March 24, 1930, No. 9426. Convention date. March 22, 1929. [Class 40 (v).] A carrier frequency is wobbled between predetermined limits at a plurality of predetermined rates to effect multiplex communication. The following example is illustrated in the Specification. A ten thousand kilocycle oscillator 1, Fig. 1, has its frequency wobbled over a band of nine hundred cycles by a forty kilocycle wobbler 3. At the receiver a tuner and radiofrequency amplifier 9, tuned to the ten thousand kilocycle wave, is coupled to a detector 15, which is supplied also with a nine thousand eight hundred kilocycle frequency from an oscillator 11, which in turn is wobbled over a nine hundred cycle band bv a thirty-five kilocycle wobbler 13. The intermediate frequency amplifier 17 is tuned to two hundred kilocycles, the difference between the carrier wave from 1, and the local oscillator 11, and the detector passes on a five thousand cycle oscillation to a further tuned amplifier for utilizattion, this frequency being produced by the beat note o:' the thirty-five kilocycle and forty kilocycle wobblers at the receiver and transmitter respectively. For multiplexing the system the carrier frequency may be wobbled at a plurality of different frequencies, each of which will give a different output frequency from the detector 19, which may be separated by appropriate filters. As a means of frequency wobbling a magnetic device may be used consisting of a core 37, Fig. 2, with a winding 33 in series with the oscillatory inductance of a Hartley oscillator 23, a control winding 39 capable of saturating the core 37 and differentially wound relative to the winding 33, being arranged inside the latter winding. Alternatively the plate potential or, in the case of a screen-grid valve, the screen potential may be wobbled to cause a frequency shift. For the prevention of fading the signals may be sent out on two or more independent transmission systems, with different carrier frequencies, controlled by the same wobbler, exactly in phase. Separate receivers are arranged to be controlled by a single wobbler, as above, and their outputs, which are in phase, are combined. Specifications 296,678 and 308,663, [both in Class 40 (v), Wireless signalling &c.], are referred to.

Title: Methods of and apparatus for manufacturing matching sheets of glass
Inventor: MURPHY NORMAN
IPC: C03B33/09
Filed: 1959-03-18
Abstract: In the manufacture of matching glass sheets by cleavage of a parent sheet, the sheet is heated and a continuous score line formed around the perimeter, the sheet then being progressively chilled simultaneously on both faces to give a thermal down shock such that the shock at the margin is 5-10 DEG  C. less than the shock in the middle area, the chilling being effected by relative movement between the parent glass and chilling streams.  The heating of the parent sheet may be such that the margin of the sheet is at a temperature, 5-10 DEG  C., less than that of the middle area which is effected for example by disposing the sheet between electric blankets with less heating capacity at the sides. Alternatively, cooling by flowing flames may have jets over a less width than the parent sheet so that the margins are cooled less. The score line is produced by a diamond or like means and the sheet heated to about 90 DEG  C., as by a furnace or by steam from a blowing frame.  Specification 810,579 is referred to.
