Title: Improvements in or relating to braking apparatus for trailer vehicles
IPC: B60T7/20
Filed: 1936-07-14
Abstract: 463,022. Trailer vehicle brakes. PROJECTILE & ENGINEERING CO., Ltd., and BRIDGES, W. July 14, 1936, No. 19571. [Class 103 (i)] In brake mechanism for trailer vehicles of the kind comprising a rocking lever on the trailer and connected to the trailer brake so that when the towing vehicle is retarded relatively to the trailer the draw-bar applies the brake, a hand lever is mounted on a fulcrum which is independent of the rocking lever and of the draw-bar whereby the brake may be applied independently of the draw-bar and rocking lever. The draw-bar D is slidably mounted in a framemember B<2> pivoted at C<1> to the trailer turntable A<1> and engages a lever F pivoted at F<1> on the member B<2>. The lever F is connected by a chain G<1>, slotted link G<2> and cable G to the brakes. A hand-lever H pivoted at H<1> extends through the link G<2> and the brake may thus be applied by the hand lever through the link independently of the draw-bar and lever F. The hand-lever has a locking device J, J<1>. The brake is also applied in the event of the coupling becoming disengaged by a chain H<3> attached to the hook E on the towing vehicle and to the lever H. A cable K extending from the link G<2> permits application of the brake from the driver's seat on the towing vehicle. To prevent application of the brake by the draw-bar when reversing the movement of the trailer, a pin L may as shown be passed through brackets F2 on the frame-member B<2> to engage the lever F. A friction damping device F<4> prevents too sudden application of the brake through the draw-bar and lever F. When the .trailer vehicle is of the type provided with Ackerman steering mechanism the member B<2> may be connected to this.

Abstract: 201,746. Hunt, R. J., and Hunt & Co., Ltd., R. July 17, 1922. Disc mills; roller mills.-Relates to grinding and crushing mills of the type comprising a. pair of crushing rollers and a disc mill associated in a single machine. The spindle of the grinding-disc and the shaft of the non- adjustable roller are connected by spur gearing and one of them i.s driven by means of a pulley, whereby side pressure on the grinding-disc due to the crushing force is eliminated. As shown, the spindle 7 of the runner 8 of the disc mill is connected by spur gearing 13, 14 to the spindle 11 carrying the non-adjustable roller 12 of the crushing-mill. The outside roller 12<a>, which is driven by friction from the roller 12, is mounted in sliding- bearings 27 movable in guides 28 and is pressed against the roller 12 by springs 29 adjustable by means of a screw 32 bearing against a plate 31. The wheels 13, 14 are enclosed in a gear-case 15, and the grinding-plates 8, 8<a> are mounted in a casing 16 having an outlet 17.

Abstract: 708,136. Magnetic structures. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Aug. 27,1951 [April 23,1951], No. 20141/51. Class 38(2) A magnetic structure for use in magnetic filters, measuring instruments and loudspeakers comprises one or more parts 4, 5 of high permeability together with a substantially flat thin permanent magnet 1 magnetized across its thickness 9 and having a coercivity of at least 750 Oersteds and a.low-remanence (e.g. less than 5,000 Gauss), the parts of high permeability having a portion 7 in which the flux is parallel to the flux in the permanent magnet and touching the permanent magnet or spaced from it by a distance 8 which is less than one half, preferably less than one quarter the thickness 9 of the permanent magnet, there being an air gap 10 adjacent an edge of the magnet. Owing to the characteristics of the permanent magnet material, there is little leakage flux at the edge 14, but by turning up the edge of part 4, the space 8 and airgap 10 are arranged circumferentially and leakage is considerably reduced. Many other constructions are described with reference to the other figures, in some the distance 8 being zero, and the airgap being partly bounded by the permanent magnet, e.g., Fig. 10. The airgap may be between a permanent magnet and either a part of high permeability, Fig. 3, when it may be used as a braking magnet for a Ferraris meter, or another permanent magnet, Fig. 12 (not shown).

Title: The preparation of petroleum resins
IPC: D21H17/62
Filed: 1963-05-22
Abstract: Petroleum resins are prepared by polymerizing in the presence of a Friedel-Crafts catalyst (e.g. boron trifluoride or ethyl ether complex thereof) a hydrocarbon mixture of petroleum origin boiling within the range 20 DEG  to 280 DEG  C. and containing aromatic hydrocarbons having a polymerizable double carbon-carbon bond, monoolefins and diolefins, and having an unsaturated aromatic hydrocarbon content (as defined in the Specification) of 15 to 80% by weight, a conjugated diolefin content (as defined) of 20 to 85% by weight and, preferably, a diene value index (as defined) of 15 to 80. The hydrocarbon mixture used can be obtained by thermal or catalytic cracking of light or heavy naphtha fractions, kerosene fractions, gas oil, residual oil or crude oil.  In examples, polymerization is effected by heating the hydrocarbon mixture under pressure to 30-60 DEG  C.  The BF3 or ether complex catalyst is removed after polymerizing by treatment with sodium hydroxide or carbonate and washing.  The resins are readily reacted with acidic compounds, e.g. acrylic acid, methacrylic acid, maleic acid or anhydride, and tetrahydrophthalic acid or anhydride, to form water-soluble products which are useful as paper sizing agents and for coating compositions, floor tiles and printing inks.ALSO:Water-soluble derivatives of petroleum resins prepared by reacting a petroleum resin with a carboxylic acid or anhydride are useful as paper sizing agents.  The petroleum resins are those obtained by polymerizing in the presence of a Friedel-Crafts catalyst a hydrocarbon mixture of petroleum origin boiling within the range 20 to 280 DEG C. and containing polymerizable aromatic hydrocarbons, monoolefins and diolefins.  The acidic reactant may be acrylic acid, methacrylic acid, maleic acid or anhydride, or tetrahydrophthalic acid or anhydride.

Title: Improvement in polymeric materials
IPC: C08G69/44
Filed: 1943-12-07
Abstract: Polyesteramides are made by heating polymerized straight-chain aliphatic monocarboxylic acids containing 17-21 carbon atoms in the chain and having at least two, and preferably two to five, carbon-to-carbon double bonds, with an aminoalcohol of which the amino group is primary or secondary, and the alcohol group is primary, secondary, or tertiary, with or without a dicarboxylic acid. The aminoalcohol may contain more than one amino or alcohol groups. The polymerized acids may be derived from any of the following oils: soya bean, corn, linseed, cottonseed, hempseed, kapok seed, herring, perilla, poppy seed, pilchard, whale, menhaden, mustard, peanut, rapeseed, salmon, sardine, walnut, rubber seed, saffower, sesame, sunflower, tung and oiticaca, and acids specified are linoleic, linolenic, elaeostearic, licanic, arachidonic, clupanodonic.  In examples: (1) polymerized soya bean acids are prepared by heating soya bean oil with methyl alcohol and sodium methoxide to give the methyl esters of the constituent fatty acids, which are polymerized by heating at 300 DEG  C. in presence of anthraquinone, the polymerized portion is separated and then saponified with alcoholic potash, and the soap obtained is acidified with hydrochloric acid. Polymerized soya bean acids so obtained are heated with (2) and (3) ethanolamine; (4) ethanolamine and adipic acid; (5) N - (b  - hydroxyethyl) trimethylene diamine; (6) diethanolamine; (7) N - (b  - hydroxyethyl - b  - cyanoethylamine); (8) b -hydroxyethyl-g -aminopropyl ether, and the products are compounded with carbon, sulphur, zinc oxide, 2-mercaptobenzthiazole with or without phenyl-b -naphthylamine and heated.  Preferably, the proportions of reactants are adjusted so that one carboxylic group is present for each amino and each hydroxyl group.  Polymerized fatty acids generally are obtained from the oils by methanolysis, polymerization, saponification and acidification as illustrated under (1) above.  N - (b  - hydroxyethyl) - b  - cyanoethylamine is prepared by adding acrylonitrile to ethanolamine with cooling.  b  - hydroxyethyl - g  - aminopropyl ether is prepared by reducing b -cyanoethyl-b -hydroxyethyl ether, which is the addition product of ethylene glycol and acrylonitrile.
