Abstract: A push-in easy opening closure for a can end (1) or similar container member formed with a resealable pressure releasing tab (4) closing an opening (5) in the can end (1) and integrally connected to the can end (1) at integral connection (6). The tab (4) is adapted to be bent about the integral connection (6) during the opening operation, and to avoid sheet metal fracture at the integral connection (6), the radius about which the tab (4) will bend in the region of the connection (6) is artificially increased by some convenient means. In a first embodiment (FIGS. 1 to 3), a raised dimple (7) is formed centrally of the integral connection (6). In another embodiment (FIG. 4), an elongate raised bead (8) is formed longitudinally of the anticipated line of bending of the connection (6). In a still further embodiment (FIGS. 5 to 7), an elongate raised bead (9) extends transversely of the anticipated line of bending of the connection (6) and to either side of said line. In a still further embodiment (FIG. 9), an abutment (11) is secured or formed on the inner face of the can end (1) adjacent to the anticipated line of bending about the connection (6). In each of the embodiments, the bending radius of the tab (4) about the connection (6) is substantially increased to effectively prevent fracture of the tab (4) occurring.

Abstract: New oil components for cosmetic and pharmaceutical applications consist of reaction products of epoxidized triglyceride oils with monohydric alcohols containing from 1 to 4 carbon atoms. The oil components are produced by reacting an epoxidized triglyceride oil containing from about 4 to about 8% by weight of epoxide oxygen, preferably an epoxidized soya bean oil containing from about 6 to about 7% by weight of epoxide oxygen, in the presence of an acidic catalyst with a monohydric C1-C4-alcohol, preferably methanol, in excess at the boiling temperature of the alcohol until the oxirane rings have been completely opened, followed by neutralizing the catalyst and distilling off the excess alcohol. The new oil components are eminently suitable, inter alia, for the production of cosmetic stick preparations.

Abstract: An open-end spinning machine is disclosed having a piecing ability employing both a yarn reserve-forming member as well as reverse rotation of the yarn withdrawal rollers and of the package drive roll to pay out yarn from the package during formation of the yarn reserve, during the start-up cycle. This permits rapid dispensing of the yarn reserve on piecing, while allowing the reserve to be formed at a controlled rate before start-up and thereby minimizing the load on any auxiliary power source taking over in the event of shut-down of a multi-station spinning machine on power failure.

Abstract: A process for the continuous preparation of 3-(methylthio) propanal. A liquid reaction medium is contacted with a gaseous acrolein feed stream in a gas/liquid contact zone. The reaction medium contains 3-(methylthio) propanal, methyl mercaptan and a catalyst for the reaction between methyl mercaptan and acrolein. The gaseous acrolein feed stream comprises acrolein vapor and non-condensible gas. Acrolein is transferred from the acrolein feed stream to the reaction medium and reacts with methyl mercaptan in that medium to produce a liquid reaction product containing 3-(methylthio) propanal. The non-condensible gas is separated from the liquid reaction product. The reaction product is divided into a product fraction and a circulating fraction, and the circulating fraction is recycled to the gas/liquid contact zone. <IMAGE>
