[Also in Division C2]  Polyamines H 2 N(CH 2 -CH 2 -NH) n H, where n is 1 to 10, are condensed with a mono- or dicarboxylic acid or ester and/or a polymerizable lactam at above 100‹ C. in the presence of 0À001 to 1 wt. per cent of an alkali metal borohydride to minimize the discoloration of the product. Specified acids are butyric, capryllic, lauric, stearic, oleic, succinic, adipic, azelaic, terephthalic, aminobutyric and aminocaproic. In examples, diethylene triamine is reacted with (1) adipic acid, (2) stearic acid, (3) dimethyl adipate, (4) ethylene diamine and adipic acid, (5) caprolactam and adipic acid, and (6) succinic acid, and (7) triethylenetetramine is reacted with adipic acid with and without the borohydride. In a comparative example it is demonstrated that a comparable effect is not achieved in the reaction of dipropylene triamine with adipic acid.

Title: Apparatus and method for analyzing hydrocarbons
IPC: G01N21/72
Filed: 1966-07-04
Abstract: 1,084,844. Measuring octane rating of fuels. UNIVERSAL OIL PRODUCTS CO. July 4, 1966 [July 13, 1965], No.29899/66. Headings G1D and G1N. In order to measure a characteristic e.g. octane rating boiling point, vapour pressure of a hydrocarbon, e.g. gasoline, it is partially oxidized to generate a stabilized "cool flame" and any one of the variables of the oxidation process is controlled so as to maintain the flame front at a predetermined distance from the burner. The value of the controlled variable is then later as an indication of the octane rating etc. In one embodiment, Fig. 1, the hydrocarbon is fed through a flow controller 34 to a burner jet 32 to which air is also supplied at above atmospheric pressure via a flow controller 27. The air is pre-heated by passing through a coil 31 surrounding a combustion tube 17 within which the "cool flame" is generated. The burner apparatus is contained within a jacketed housing 10 through which a thermostatically controlled heating fluid is circulated. The position of the flame front of the "cool flame" is detected by a differentially connected pair of thermocouples (or resistance thermometers, or radiation pyrometers, or photo-electric pyrometers, or a flame ionization sensitive capacitor, or a direct current ionization gap) and any deviation is caused to control the back-pressure on the exhaust line 39 to restore the flame front to its correct position. The pressure in the exhaust line is taken as a measure of octane rating etc. In other embodiments, Figs. 5 to 7 (not shown) the flame position is restored by control of the rate of flow of the hydrocarbon, the rate of flow of air or the temperature of the fluid that heats the jacket. The measured valve may be used for automatic process control.

Abstract: 1,272,752. Tractor/trailer hitch. WINGET Ltd. 20 June, 1969 [24 June, 1968], No. 30006/ 68. Heading A1P. A first coupling part on a tractor can be raised and lowered by means of a hydraulic piston 66 and cylinder 68, into and out of engagement with a second coupling part on a trailer. The two parts are locked together by means of an expanding pin 60 sliding in holes 77, which pin is controlled by a double acting pneumatic cylinder 49 and piston 48. The coupling allows movement of the trailer by allowing rotation in a horizontal plane around bearing members 37, 38, and in a vertical plane around bearing sleeves 24. Engagement of the coupling also raises a supporting foot when the lower end of the push rod 78 is raised in a locating box 45. When the coupling is locked together weight on the rear axle of the tractor may be effectively moved foreward by the extension, controlled by a relief valve, of the hydraulic piston and cylinder 66, 68.

Abstract: 1,034,107. Thermionic cathodes. THORNAEI RADIO VALVES & TUBES Ltd. July 9, 1963 [Aug. 3, 1962], No. 30009/62. Heading H1D. In a method of making emissive cathode material suitable for formation into cathode structures, an alkaline earth material is applied to a sintered layer of metal powder on a metal substrate, and thereafter subjected to pressure to consolidate the layer of sintered metal and alkaline earth material and reduce its thickness from an initial value of about 50Á to a value in the range 12-25 Á. In particular, a strip of cathode nickel alloy may be coated with a suspension of carbonyl nickel powder, 2-3 Á particle size, in an organic binder, e.g. nitrocellulose or methyl methacrylate, by spraying, brushing &c., or electrophoresis. After sintering at 800-1000‹ C. in a hydrogen-containing atmosphere, this layer is impregnated with a co-precipitated alkaline earth carbonate mixture comprising, by weight, 55% barium, 41% strontium, and 4% calcium carbonate, suspended in a solution of nitrocellulose. After drying, the impregnated layer is compacted between rollers. A specific example is given. The coated strip is used to form cathodes for thermionic valves, the organic binder being driven off, and the carbonates converted to oxides, during valve processing.

Patent GB-988548-A (GB)
Title: Method for preparing polyester resins
IPC: C08G63/78
Filed: 1962-08-03
Abstract: Low molecular weight linear polyesters are made by adding a free dicarboxylic acid and a glycol to a linear polyester having an average degree of polymerization of 3 to 20 and heating the resulting mixture at a temperature above the melting point of the polyester but below the distillation temperature of the glycol until a polyester having an average degree of polymerization of 3 to 20 is formed.  The starting polyester may be made by polymerizing a glycol ester of a dicarboxylic acid or by depolymerizing a high molecular weight polyester in the presence of a glycol.  The dicarboxylic acid and the glycol may be added to the starting material either alternately or simultaneously. With the latter method, a continuous process may be effected by withdrawing polyester from the reaction mixture at the same rate as the reactants are added.  The reaction may be effected in the absence of a catalyst or in the presence of zinc acetate, manganous acetate or an alkali metal alcoholate.  The low molecular weight polyester product may be polycondensed to a high molecular weight fibre-forming polyester by a batch or continuous process in the presence of a catalyst, e.g. antimony trioxide, zinc borate, litharge, lead acetate or magnesium oxide and, possibly, tritolyl phosphate. The preferred dicarboxylic acid is terephthalic acid, but instead of or in addition to this there may be used oxalic, succinic, adipic, sebacic, 2:6-naphthoic, tetra- or hexahydroterephthalic, p:p1-diphenyl dicarboxylic, orthophthalic or terephthalic acid.  The glycol may be a polymethylene glycol having 2-10 carbon atoms, a cyclohexanediol, cyclohexanedimethanol, di-beta-hydroxyethoxybenzene or 2:2 - bis - [4 - (beta - hydroxyethoxy)phenyl]propane. Examples describe the production of polyesters from ethylene glycol and terephthalic acid or a mixture thereof with isophthalic acid.
