Title: Improvements in or relating to the polymerisation of acrylic acid esters
IPC: C08F220/12
Filed: 1934-12-03
Abstract: Acrylic acid esters, e.g. the methyl or ethyl ester, or mixtures thereof with one another or with other polymerizable compounds, e.g. acrylic acid nitrile, methacrylic acid esters, vinyl acetate, styrene or butadiene, are polymerized in the presence of one or more substances wholly or partially consisting of unsaturated cyclic compounds of the terpene series, e.g. ethereal oils such as turpentine oil or melissene oil, or colophony, which may be used in quantities of not more than 20 per cent, preferably about 1 per cent or less, e.g. about 1 per cent of turpentine oil or about 0,1 per cent of colophony.  There may also be added, before or after polymerization, other substances such as softening agents, e.g. phthalic acid esters, acetins, butyl phosphate, butyl stearate or diethylene glycol monomethyl ether.  The polymerization may be effected by the usual methods, e.g. by the action of oxygen or substances evolving it, such as hydrogen peroxide or benzoyl peroxide, or by the application of pressure, heat or light, and may be carried out with the monomeric bodies wholly or partially in solution or emulsion.  The process is applicable to the production of safety glass by applying the monomeric substance to the glass and effecting polymerization between the plates.  Specification 401,653 is referred to.  The Specification as open to inspection under Sect. 91 contains examples describing the polymerization, by heating in the presence of benzoyl peroxide, of: (1) methyl acrylate in the presence of oil of turpentine; (2) methyl methacrylate in the presence of rosin; (3) a mixture of ethyl and n-butyl acrylates in the presence of rosin.  This subject-matter does not appear in the Specification as accepted.

IPC: D01F2/10
Filed: 1959-10-16
Abstract: Viscose containing a regeneration-retardant mixture of polyethylene glycol and dimethylamine in amounts varying from 0,05 to 0,5% each, based on the weight of the viscose, is spun into a coagulating acid spin-bath and the filaments stretched at least 70% while in contact with the spin-bath and withdrawn from the stretching operation at a speed of at least 70 metres/min. Polyethylene glycol having a molecular weight of 1000-2000 may be used, and desirably both the polyethylene glycol and dimethylamine are added in amounts of 0,1% each by weight to the viscose prior to spinning.  Formaldehyde may be added to the viscose in addition to the polyethylene glycol and dimethylamine and the viscose spun into a zincfree acid spin-bath. While in contact with the spin-bath the filaments are preferably stretched in excess of 100%, and then given a secondary stretch in excess of 15% in a more dilute acid bath.  The spin-bath suitably contains 7,0-10% weight sulphuric acid and 1-10% by weight zinc sulphate, expressed as the anhydrous salt, and is suitably at 50 DEG -70 DEG C.  In forming the viscose, cellulose xanthate having a uniform chain length at a degree of polymerization of 300-800 may be used, and the proportions of cellulose and sodium hydroxide in the viscose may range from 4-13% cellulose with from 5-13% sodium hydroxide.  The viscose may be spun at a salt point of 4-20, preferably 10-12 or 14-20.  Filaments so made are of high tenacity and suitable for the manufacture of tyre cord.

Title: New and improved high-frequency electric signal-selecting systems
IPC: H03G5/26
Filed: 1936-12-23
Abstract: 470,450. Wireless receiving-circuits. HAZELTINE CORPORATION. Dec. 23, 1936, No. 35257. Convention date, Jan. 28. [Class 40 (v)] The width of one sideband is automatically adjusted, independently of that of the other sideband, and inversely in accordance with the amplitude of undesired signals on frequencies near the desired frequency and at the same side thereof as the adjusted sideband. The intermediate-frequency band-selector 14 of a superheterodyne receiver comprises a transformer 25, the primary 26 and secondary 27 of which are tuned to the I.F. and are magnetically coupled and capacity coupled by condensers 30, 31 to the junction of which are connected two parallel paths to earth, one over condenser 32, the other over condensers 33, 38 and valve 36 which forms an adjustable shunt impedance to the coupling 30-31. The total sum of the reactances of condensers 30, 31, 32 and 33 should be greater than the minimum apparent resistance of valve 36. The inductive coupling comprises a link circuit 34, 35 which is similarly shunted by a variable impedance constituted by valve 37. The last intermediate frequency coupling preceding the second detector comprises a tuned transformer 17, the primary circuit of which is split to provide input connections to a pair of systems 44, 45, the former being tuned by circuit 47, 48, 49 which has a response characteristic with a peak at about 10 kc. above the I.F., while system 45 has a peak response due to circuit 47a, 48, 49 at a frequency 10 kc. below the I.F. The amplifiers 46 feed diodes 50, the load-resistances 57 of which constitute the biassing sources of valves 36, 37. Thus an interfering carrier, the l.F. of which lies above the desired I.F: increases the conductance of valve 36 and reduces the capacity coupling 30-31, reducing the band width and simultaneously lowering the mean resonant frequency of the selector 14, virtually contracting the upper sideband. Similarly, in the case of an interfering I.F. carrier below the desired I.F., the inductive coupling 34, 35 is reduced by valve 37 and the lower sideband is contracted. Where interference is present on both sides, the bands are contracted unequally in proportion to the amplitudes of the interfering signals.
