Abstract: Improvements in the production of polyesters of dicarboxylic acid moieties and 1,4-butanediol moieties, where at least some of the acid moieties are aromatic, by catalytic direct or transesterification of the acids or esters thereof with a molar excess of 1,4- butanediol, whereby reducing the amount of excess 1,4-butanediol required to produce commercially acceptible polyesters, which comprises reacting the 1,4-butanediol with the dicarboxylic acid or an ester thereof in a mole ratio of 1.05 to 1.25:1 respectively at temperatures of less than 200*C while distilling off the volatile cleavage products including the 1,4butanediol until the flow of butanediol has been reduced to less than about 10 percent of its initial removal rate, and then polycondensing this product at temperatures above 200*C in the usual manner.

Abstract: Warhead for bombs, projectiles, rockets and the like having a casing with several projectiles accommodated therein. The projectiles are disposed in launcher tubes which are connected with each other by a common central connecting component to form an independent unit in a symmetrical arrangement with respect to the axis of the component. The independent unit is equipped with a descent-retarding device on one side thereof positioned toward one direction of the axis, while the other side is provided with a stabilizing device toward the other direction of the axis to vertically position the axis during descent. Preferred embodiments use parachutes as descent-retarding devices and rigid stabilizer rods or flexible members to interconnect a stabilizing weight with the respective independent units. Accommodations are made to telescope the stabilizer rods into one another to limit the total space utilized in the stored position. In the embodiments utilizing flexible members, the weights are provided with a recess at the undersides thereof to accommodate the next adjacent parachute and independent unit when in the stored position in the warhead.

Abstract: Cross-linked vinyl chloride polymers are produced by employing as the linear vinyl chloride polymer a copolymer of vinyl chloride and a silane and effecting the cross-linking by contacting the linear polymer with hydrochloric or nitric acid. Premature cross-linking, i.e. cross-linking before final shaping of the desired article such as filament or sheet, can be avoided by use of the process of the invention.
