Title: Mixed organic-inorganic esters, the manufacture thereof and the conversion thereof into unsaturated esters and alcohols
Filed: 1955-01-28
Abstract: The invention comprises halogenated esters of 1 : (3) : 6-di- or trimethyl octane 1 : 3-diol, and dihalophosphato esters of the same compound, or containing in 3-position, the residue of a mono-valent non -OH- containing halogenated inorganic acid, and a process for preparing the products by treating the corresponding di-or tri-methyl octane diol with an acylating agent to give the ester, followed by an inorganic non-hydroxylic-halogen-containing esterifying agent to esterify the 3-group.  The products may be further treated to convert them into unsaturated derivatives by heating in presence of an acid acceptor, hydrolysing to the alcohol and re-esterifying.  In examples, the 3 : 7-dimethyl octane diol 1 : 3, obtainable from 6-methylheptanone-2 by the Darzens reaction via the 3 : 7-dimethyl 2 : 3-epoxy-ethyloctanoate by reduction with LiACH4, is esterified with acetylchloride, or benzoylchloride, followed by POCl3, or HCl, or HBr, to give the 1-acyl-3-halo- or halophosphato-3 : 7-dimethyl-octane; the 1-acetyl-3-halo or halophosphato derivatives on heating in pyridine are converted to mixtures of unsaturated 1-esters, which are hydrolysed to unsaturated 1-alcohols and re-esterified with formic acid, isobutyric anhydride, and benzoyl chloride, to give mixtures of unsaturated esters; a similar series of reactions is performed with 3 : 6 : 7-trimethyl octane-diol-1 : 3, to give mixed halo- or halo-phosphato-organic esters, convertible into the corresponding unsaturated esters, alcohols and new mono esters.

Abstract: 584,923. Valve amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd., and JACOBSEN, B. B. Feb. 11, 1944, No. 2607. [Class 40 (v)] In an impulse receiving system wherein a selective amplifier is arranged to .amplify only those frequencies necessary for defining the pulse, means are provided for limiting the amplitude of the signals applied to the amplifier. This is shown mathamatically to reduce the effect of noise interference. The amplifier Al, of the type described in Specification 581,683 is fed with signals through limiter L1, which limits the instantaneous peak amplitude, and may consist of a biassed diode shunting the signal path. A further linear amplifier A2 feeds a high pass amplitude limiter L2 which cuts off all signals below a predetermined level and may comprise a biassed diode in series with the signal path. Variations of signal input level may be reduced by the use of an A.G.C. circuit fed from the output of amplifier A2 and controlling the signals applied to limiter L1.

Abstract: 563,391. Alloys; annealing. THOMPSON PRODUCTS, Inc. Feb. 17, 1943, No. 2634. Convention date, Jan. 24, 1942. [Classes 72 and 82 (i)] [Also in Group XXII] The hollow bead of a poppet valve for an aircraft engine or like metal article is strengthened by first forming it with a domed hollow head 12a, confining this around its periphery and flattening the dome, to cold-work it. The blank 12 may be formed by piercing a billet of steel containing 14 per cent of nickel, 14 of chromium, 2.5 of tungsten and 0.35 of carbon to form a dome-ended thimble and then reaming its bore 11c, Fig. 3, to form an enlarged end 11d. This thimble may be necked at' 11 by rotating between hammer dies and forced between reducing dies to close and extend the shank 11b as at 12c, Fig. 5, but leave a slightly enlarged end on it. A groove 13 may be machined in the head 12a and filled with a deposited alloy, such as that known under the Registered Trade Mark " Stellite." The hot blank 12 is then placed in a split die 15, formed to fit the periphery of the head and part of the shank, and the dome 12a is flattened and thereby thickened by a die 16, when the temperature has fallen below the recrystallization point of the steel from which the blank is made. The blank 12 is then removed from the die 15, the shank 12c is drilled, sodium or other coolant is introduced, and the enlarged end of the shank is collapsed and plugged. The valve may then be heated to 300-500‹ F. to restore its elastic limit without destroying the benefits of the coldworking. The Specification as open to inspection under Sect. 91 includes a reference to U.S.A. Specification 1,984,751. This does not appear in the Specification as accepted.
