    摘要： A method of manufacturing chlorine-free cyclopropanecarboxylic acid methyl ester is described wherein a first portion of alkali methoxide is added to a high-boiling solvent, followed by a second portion of methoxide with an equimolar portion of 4-chlorobutyric acid. The ester product can be readily hydrogenated catalytically to the corresponding carbinol.

    摘要： In the preparation of alkyl halides from cycloaliphatic olefins and hydrohalic acids, the reaction is carried out at a temperature below the boiling point of the olefin without the addition of catalyst and without a solvent. At a high olefin conversion rate, alkyl halides are obtained with high selectivity and with very good color quality.

    摘要： A gun includes a barrel arranged to execute a recoil and a counterrecoil after a shot is fired; a trunnion about which the barrel is pivotal in a vertical plane to assume an index position and firing positions situated at an angle to the index position; a case ejector for ejecting a case from the barrel during counterrecoil; and a counterrecoil blocking device for interrupting the counterrecoil as long as the barrel is in a firing position other than the index position and for allowing the counterrecoil to resume when the barrel assumes the index position, whereby case ejection by the case ejector is effected in the index position.

    摘要： A recoil brake for controlling recoil and counterrecoil movements of a gun includes a brake cylinder; a piston slidably received therein; a hollow piston rod affixed to the piston and arranged for connection to a breechblock of the gun; a throttle passage for braking the motion of the piston; a buffer spear affixed to an end of the brake cylinder and extending within the hollow piston coaxially therewith; and a buffer spear chamber within the piston rod; a throttle sleeve affixed to the piston and extending therewithin, surrounding the buffer spear. The throttle sleeve and the piston rod define an annular inlet channel, while the throttle sleeve and the buffer spear define an annular outlet channel. A check valve is located between the inlet and outlet channels, and it opens solely in response to pressure in the inlet channel when the piston moves in a direction outwardly of the brake cylinder (recoil movement). An axially extending throttle groove is provided in the outer surface of the buffer spear. Further, there is provided an annular guide which is formed on the throttle sleeve and which surrounds and slidingly contacts the buffer spear. The annular guide cooperates with the throttle groove for forming a constricted passage for the hydraulic fluid as it flows from the buffer spear chamber through the outlet channel to one side of the piston as the piston moves into the brake cylinder (counterrecoil movement). Cross-sectional passage areas of the throttle groove along a length thereof determine the extent and the path length of the braking effect for the counterrecoil movement of the gun.

    摘要： A pneumatic recuperator mechanism has a sealable valve which communicates a storage chamber with a displacement chamber; the mechanism includes a recoil piston which is connected to the gun barrel and is slidable jointly with a piston rod; the mechanism is improved in such a way, that with a predetermined built-in cross section a simple and light recuperator mechanism with a high heat-free operative readiness is formed.This object is achieved in that the displacement chamber 1 and the storage chamber 2 have the same inner diameter d and are arranged within only one cylinder 3, whereby the recoil piston 5 and the valve 6 are slidably received by the inner wall 4 of the cylinder 3. The valve 6 is advantageously in the shape of a disc and the recoil piston 5 is offset relative thereto. The valve 6 as well as the recoil piston 5 are provided with wear-resistant and delay-free seals 18, 24, 36 and guide bands 7, 23. The arrangement of the recoil piston 5 and the valve 6 permit a lower operative pressure level of the pneumatic working medium with a higher delay-free operative readiness.
