Title: Novel amides and process for preparing same
Inventor: MILKS JOHN EDWARD
IPC: C08K5/20
Filed: 1966-08-03
Abstract: Synthetic plastics materials contain as an antistatic agent a compound of the formula <FORM:1103157/C3/1> where R is hydrogen, alkyl or alkenyl, n is 0 or 1 and R1 is hydrogen, alkyl or hydroxy-alkyl when n is 1 and hydrogen when n is 0.  In an example, N - (2,3 - dihydroxypropyl) - stearamide is incorporated into high-density polyethylene to form a composition having good antistatic properties.ALSO:Compounds of the general formula <FORM:1103157/C2/1> where R is hydrogen, alkyl or alkenyl, n is 0 or 1, and R1 is hydrogen, alkyl or hydroxy-substituted alkyl when n is 1, and hydrogen when n is 0, are prepared by reacting an appropriate glycidyl ester of an organic acid containing an a -carbon, unbranched chain with a nitrogen compound of the formula R1(CH2)nNH2, preferably using excess amine.  The compounds have antistatic properties.

Title: Recovery of styrene
IPC: C07C7/04
Filed: 1972-07-26
Abstract: 1398855 Distilling hydrocarbons HALCON INTERNATIONAL Inc 26 July 1972 [27 July 1971] 34976/72 Heading C5E Styrene is recovered from a mixture containing it and also alphaphenylethanol, styrene polymers, acetophenone and ethylbenzene by distillation in the presence of elemental sulphur as a polymerization inhibitor, and the amount of acetophenone present in the liquid phase is controlled so that the mole ratio of acetophenone to acetophenone plus alpha-phenylethanol is at least 0À4. The mixture may be that resulting from the oxidation of ethylbenzene to alpha-phenylethanol as principal product by dehydration to styrene. The high proportion of acetophenone suppresses the formation of volatile sulphur compounds by reaction between sulphur and alpha-phenylethanol, and is attained by adding acetophenone as a cutback oil or at any convenient point. In a typical embodiment, ethylbenzene and more volatile materials are removed in a first distillation, and styrene is separated from less volatile materials in a second distillation, in the presence of acetophenone which remains in the bottoms. There may be a third distillation of this residue to recover further styrene, and a fourth distillation to recover acetophenone and alpha-phenylethanol, leaving sulphur, polymers and tarry materials as residue. The acetophenone in the mixture can be hydrogenated and the mixture recycled to dehydrogenation, or the mixture can be separated and the acetophenone either hydrogenated or recycled to the distillation.

Abstract: 650,679. Air vessels for reciprocating pumps. FLUOR CORPORATION, Ltd. Nov. 26, 1946, No. 35053. Convention date, Nov. 27, 1945. [Class 102(i)] [Also in Group XXIX] An arrangement for eliminating pulsations in a liquid stream having a continuous pulsating flow through a conduit comprises a pair of hydraulic accumulators each connected to the conduit at spaced locations therealong, the accumulators ,being closed except for the connections and another valve controlled connection to each chamber supplying gas under pressure the gas compressing and expanding in response to increasing and decreasing pressure in the liquid in the conduit and a tube in the conduit between the connections. Fig. 1 shows a cross-section of an hydraulic accumulator 11 of the type employing a flexible bladder 15a filled with gas under pressure supplied through a pressure regulating valve 20. The valve maintains the pressure at a desired value which can be adjusted. Any suitable known valve may be used to maintain a constant pressure in the accumulator. The liquid may be on the inside of the bladder. Fig. 4 shows two accumulators 11 connected to a conduit 10 a restriction 26 being located between them. There may be an additional restriction in the conduit either upstream or downstream of the accumulators. The restriction may comprise either a very short or a relatively elongated tube. The pressure of the gas in the accumulators can be adjusted to suit the fluctuations of pressure likely to be encountered. Details of pressures, pipe sizes &c. for specific installations are given. The Specification as open to inspection under Sect. 91 comprises also arrangements in which a single restriction is associated with a single accumulator. Restrictions comprising a tube 25 of relatively elongated form, Fig. 6 (Cancelled), may be employed. Arrangements are also shown comprising two accumulators associated with one or two restrictions but not including a restriction between the accumulators. The restriction may be in the form of an orifice plate. A restriction may be located in the connection between the conduit and an accumulator. This subject-matter does not appear in the Specification as accepted.

Title: Process of polymerising butene-1
IPC: C08F110/08
Filed: 1964-08-27
Abstract: Polymers of butene-1, are made by effecting the polymerization of the butene in the presence of a solvent consisting of a mixture of branched chain hydrocarbons comprising from 85 to 95% by weight of iso-octane, the remainder being chiefly isononane and isoheptane, and a catalyst, at a temperature of from 50 DEG  to 90 DEG C. and under a pressure of from 50 p.s.i. to 175 p.s.i., and terminating the polymerization by adding water to the polymerization mixture, while the mixture is at 50 DEG  C. to 90 DEG  C., in an amount sufficient to precipitate the catalyst but insufficient to precipitate a substantial amount of the polymer, separating the resulting catalyst precipitate from the solvent-water mixture containing polybutene-1, cooling the mixture to precipitate the bulk of the polybutene, and recovering it from the liquid. After the removal of catalyst, an aliphatic alcohol may be added to aid the precipitation of the butene-1 polymers. The process may be effected continuously or batchwise.  The catalyst is preferably of the Ziegler-Natta type. The exemplified catalyst is TiCl3 admixed with diethyl aluminium chloride. The process may be effected in the presence of hydrogen.

Abstract: 310,314. Kraft, H. B. April 23, 1928, [Convention date]. Dynamometers; systems for testing motor vehicles.-Comprises a pair of chairs upon which the opposed wheels of a vehicle with the brakes set are supported and which are movable in parallel paths at right angles to the axes of the wheels in order to rotate the wheels against the influence of the brakes, means for moving the chairs, and means for indicating the power to cause movement of the chairs. A braced structure is built up of channel and angle irons so that at one end there are inclined tracks 5 flared at one end to enable the vehicle to be driven on to the support. The tracks 5 have horizontal portions 5<c> aligned with horizontal tracks 2 and end tracks 6 which latter are curved upwards as shown. Aligned with the tracks 2 are chairs 8 also of channel section which slide relatively to the track 2 and are supported on flanged rollers 11 supported in side bars 7 of the structure. Upposite chairs are connected by an equalizer bar 12 slotted longitudinally at each end to engage a king bolt 14 connected to a chair 8 and passing through longitudinal slots 13 in the side bars 7. Each bar 12 is pivotally connected at the centre to the rod 16 of a fluid pressure piston and cylinder device 17. Fingers 21 stand up from a fixed shaft 19 to which they may be adjustably clamped. With the vehicle on the support, the fingers 21 embracing the front axle to prevent movement, and the brakes applied on the front wheels, pressure fluid is admitted to the front cylinder 17 to retract the rod 16 until the four wheels are turned. The pressure is then noted on a gauge 27. If the brakes on both wheels are equally adjusted they move at the same time, but if unequally adjusted one moves before the other and the bar 12 takes up a slanting position. From the test made, the brakes can be equally adjusted to a given pressure. Fluid is then admitted at the other end of the cylinder 17 to return the chairs to the first position. Similar tests are made on the back wheels.
