Abstract: Abstract:         In a rotary magnetic head helical scan type of video tape recorder using a segment recording system, a video signal of one vertical scanning period is divided into n video signal blocks, where n is an integer equal to or larger than 2.          A redundant period having a predetermined period is inserted into the video signal blocks in the recording mode.  Each of the video signal blocks  has a number of horizontal scanning lines equal to or smaller than N/n, where N is the number of horizontal scanning lines in a field of the video signal.  In the reproducing mode, a time axis error of reproduced series of the video signal blocks is corrected, at least during the redundant periods.  The corrected blocks are then converted into the original video signal.  The system has the advantage of correcting for the skew that arises in prior art systems.

Abstract: ABSTRACT A temperature-compensated low noise oscillator device includes a temperature sensing section, a control section and an oscillating section.  The temperature sensing section includes a temperature sensor for sensing an ambient temperature to provide a temperature data signal representative of the sensed temperature and an analog-to-digital converter for converting the temperature data signal to a first digital signal having a first digital value.  The con-trol section converts the first digital signal to a second digital signal having a second digital value.  More particularly, the control section converts a variation in the first digital value to  time-divided fractional variations in the second digital value.  The oscillating section includes a converter for converting the second digital signal to a frequency control signal and a voltage-controlled oscillator responsive to the frequency control signal for changing the oscillation signal frequency thereof.

Abstract: ABSTRACT            A jug for pouring liquids such as milk packaged in flexible rectangular pouches has a cross section and height such as to enclose the bag for its full height, the base of the jug being inclined so as to tilt the bag against a flattened front wall of the jug with a top corner projecting through a spout opening where it can be cut to form a pouring spout. The jug has a removable lid which is arched and has in-turned side flanges which are pressed apart by out-turned side flanges at the top edges of the sides of the jug as the lid is pushed forward onto the jug so that the lid fric-tionally grips the jug.  Rearward and downward pressure on the arch of the lid tends to force the inturned flanges apart and release the lid.

Abstract: A loud speaker system comprises one sub-enclosure which is closed or almost closed and a second sub-enclosure which is open placed in juxtaposition to the first. Both enclosures contain loudspeakers. This enables reproduction of low pitched sounds without resonance peaks. Two loudspeakers have a resonance frequency at almost the same frequency. The two resonance peaks interfere, cancellation is obtained by suitably mounting the speaker enclosures to give a phase reversal of 180 deg. several positional arrangements of the sub-enclosures are possible giving the listener the most suitable sound effects and sound diffusion.

IPC: C07C219/20

Abstract: For the analytical and preparative separation of the optical isomers of optically active alkanolamines into their optically pure antipodes a new resolution method is presented which involves an ester formation of the alkanolamines with optically pure and symmetrically O,O disubstituted (R,R)- or (S,S)-tartaric acids. The derivitization reactions are carried out in aprotic solvents and the primary and secondary functions are blocked via ion-pair formations with strong acids, e.g. dichloroacetic acid. The tartaric acid anhydrides are predominantly used as reagents but other ester formation methods are also practicable. The mixture of the diastereomeric alkanolamine tartaric acid monoesters are separable into their optically active and pure isomers by various chromotographic separation techniques, e.g. straight or reverse phase LC, but also by extraction methods e.g. Soxhlet extraction. The optically pure parent alkanolamine isomers can be obtained by ester hydrolysis, with high yield, from the optically pure fractions of the alkanolamine tartaric acid monoesters.
