Title: Bituminous compositions
IPC: C08K5/20
Filed: 1948-08-06
Abstract: Polyamines obtained by condensing an a ,b -unsaturated aldehyde with ammonia or amines, are subsequently catalytically hydrogenated under pressure.  Specified aldehydes are acrolein, methacrolein, a -ethyl-, a -propyl-, a -isopropyl- and the a -butyl-acroleins.  Liquid ammonia or aliphatic primary amines having 1-20 carbon atoms are preferred as the other reactant, and reaction temperature varies between -70 DEG and +150 DEG  C.  If the hydrogenated product is water-soluble it is insolubilized by treatment with an organic acid-preferably having more than 6 carbon atoms in the molecule-at 100-300 DEG  C. for 5-180 minutes. Acids specified are oleic, linoleic, stearic, naphthenic and tall oil.  Specification 619,219, [Group V], is referred to.ALSO:A minor proportion of one or more water-insoluble materials of the group consisting of polyamines obtained by hydrogenating the condensation product of an a ,b  unsaturated aldehyde and ammonia or an amine, and the organic acid salts and amides of such polyamines is added to bituminous substances.  Aldehydes specified are acrolein, methacrolein, a -ethylacrolein, a -propylacrolein, a -isopropyl acrolein, the a -butylacroleins and their homologues which correspond to the formula <FORM:0658424/V/1> wherein R1 is hydrogen or an alkyl group.  Primary amines preferred are aliphatic in which the alkyl group has from 1-20 carbon atoms, and the reaction temperature is between -70 DEG  C. and +150 DEG  C., but liquid ammonia is particularly effective.  The hydrogenated polyamines which are water soluble are rendered insoluble by treatment with an organic acid-preferably having more than 6 carbon atoms in its molecule-at 100 DEG  to 300 DEG  C. for 5-180 minutes.  Oleic, linoleic and stearic acids are specified, but saturated cyclic acids, e.g. naphthenic, and crude natural products, e.g. tall oil, may also be used.  Acidic, e.g. granite, quartz and felspar, aggregates, basic aggregates, e.g. limestone type, and metals, glass and cement may be coated with the bituminous compositions.  The percentage, by weight, of the materials added to the bitumens is between 0.25 and 5.0.  In an example, the condensation product between acrolein and liquid ammonia is hydrogenated under pressure, and insolubilized with oleic acid at 240 DEG  C. for 15 minutes.  In other examples, naphthenic acids and tall oil are used for insolubilizing. Specification 619,219 is referred to.

Abstract: 1,102,136. Colour television tubes. COMPAGNIE FRANCAISE DE TELEVISION. 12 May, 1966 [20 May, 1965], No. 21234/66. Heading .H1D. A colour television cathode-ray tube incorporates a screen with red, green and blue luminescent phosphor strips or dots and three adjacent electron guns of substantially equal length, adapted to emit high-intensity electron beams (e.g. 100 ÁA.) toward the different phosphors, respectively, wherein the diameter of the gun (defined as the largest diameter among the cylindrically shaped control, acceleration or focussing electrodes), associated with the blue phosphors is smaller (4 to 5 mm. diameter, for example) than that of the other two guns, 8 to 9 mm. diameter, for example. To promote compactness the blue gun diameter can be reduced below, and spot size proportionately increased above, the normally acceptable values since the brightness of the picture is provided essentially by the red and green components except in large areas of sea, sky and the like where good definition is not important. The axes of the three guns may be substantially aligned with the blue gun in the central position, or the blue gun may be displaced to allow the red and green guns to be mutually closer for instance. Reference is made to oblique phosphor strips horizontally swept by the three beams.

Abstract: 151,574. Adams, A. J. June 21, 1919. Turning-gear.-In a starting-device having means for turning the engine shaft intermittently and for holding it in any angular position to which it is moved, the engine shaft is turned by means of a handle or lever acting through a radially-expanding clutch comprising pivoted spring-pressed pawls which transmit motion in one direction only and are disengaged if the engine starts backwards. In the form shown, the pawls y, Fig. 3, are pivoted upon a sleeve v and urged by springs 11 into engagement with the inner periphery of a fly-wheel or drum x on the engine shaft. The pawls y lock with and rotate the drum in the counterclockwise direction only, and if the engine starts backwards they are disengaged by lugs 14 on a stationary plate 13 carried by an adjustable arm 15. The drum x is held after each counter-clockwise turn of the sleeve v by a pivoted detent 22 on a frame 24 pivoted on a fixed base 26 and held by a stop 29, the detent 22 being held in engagement with ratchet teeth 21 on the drum by a spring 27 and a weighted arm 31 which abuts at 33 against the frame 24. Owing to the shape of the teeth 21, the detent is disengaged if the engine starts backwards. The sleeve v carrying the pawls y is actuated by means of the change-speed lever a, Figs. 1 and 2, which is moved into a special slot f in the quadrant d and rocked to and fro. An arm c on the shaft b of the lever a engages a selector bar g connected through links j, m, q with an arm t on the pawl-carrying sleeve v. To prevent noise when the engine is running, the detent 22 is disengaged from the drum x, when the lever a is moved out of the slot f, by means of a spring- controlled tappet 34 on the arm t which engages an arm 32 rigid with the detent. Ignition at starting may be effected by driving the ordinary magneto or a separate magneto at a relatively high speed, as described in Specifications 151,357, 151,564, and 151,565, [all in Class 35, Dynamoelectric generators &c.]. Specification 151,099 is also referred to.
