Abstract: New derivatives of d-dehydro-vitamin A obtained by vinylating or ethynylating and subsequently partially hydrogenating 1-¢3-methyl-octa-1-yne-3,5-dien-7-on-1-yl!-2,6- -dimethyl-cyclohex-1-ene or its 5- and/or 6-methyl derivatives, converting the resulting alcohols to the corresponding derivatives of 8-dehydro-vitamin A halides by reacting with thionyl chloride or phosgene, and if required converting the resulting alcohols or halides to the corresponding trialkylphosphonium salts or triarylphosphonium salts, or reacting the 8-dehydro-vitamin A halide derivatives with alkali metal salts or alkaline earth metal salts or anhydrides of lower carboxylic acids. The new compounds can be partially hydrogenated to the corresponding polyene compounds, in which case the cis-trans isomer mixtures first obtained can be rearranged in the conventional manner to the physiologically active all-trans compounds. Accordingly, the process provides a method for the total synthesis of vitamin A, and of other compounds or the carotinoid series, which is independent of the Wittig ylide synthesis.

Abstract: This invention relates to a tape transport mechanism, particularly an improved contact winding tape transport system modified to protect it against tape transport disturbances occasioned by mechanical impacts. A shock-resisting coupling means is provided which is allocated to the reel carriers and which allows slow movements of the carriers toward and away from a drive capstan during normal working of the mechanism but prevents sudden movements of the carriers induced by mechanical shocks for instance. Piston/cylinder assemblies and magnetic rope/drum arrangements are disclosed as such shock -resisting means. The transport mechanism can be used advantageously in portable apparatus, preferably in magnetic tape recorders and especially in video cameras.

Abstract: A process for resolving racemic alpha -hydroxy- beta , beta -dimethyl- gamma -butyrolactone, referred to as D,L-pantolactone, into its optical antipodes, based on the separation of diastereomeric salts of D,L-pantoic acid ( alpha , gamma -dihydroxy- beta , beta -dimethylbutyric acid), produced from D,L-pantolactone, by means of (-)-3-aminomethylpinane, (+)-3-aminomethylpinane or one of their acid addition salts, as a new resolving agent.

Abstract: A transport apparatus for tape-like recording media in which a central capstan having a resilient peripheral portion simultaneously drives two tape reels. According to the invention, this peripheral portion has regions of different resilience produced, for example, by an elastically deformable annular insert which may be helical in shape. The tape transport apparatus of the invention can be advantageously used with all kinds of tape-like recording media, especially magnetic tapes for the recording/playback of high frequency signals, especially color video signals.
