In an example acrolein (purity 98%) methyl vinyl ether and zinc chloride were placed in an autoclave, and the resultant mixture was heated up to 90 degrees C in 15 mins with stirring, kept at 90 degrees C for 30 mins and cooled. The resulting colourless transparent liquid was analyzed by gas chromatography, to indicate no unreacted acrolein present. The reaction product was washed with water and distilled to give at first unreacted methyl vinyl ether and then 2-methoxy-3,4-dihydro-2H-pyran as a distillate boiling at 127 degrees C. The yield from acrolein was 95%.

Patent DE-2336212-A1 (DE)
Title: Varnish coat adhesion strength testing method - involves hard cutter which is applied to varnish at specified angle
Inventor: SOMMER BERND
IPC: G01N19/04
Filed: 1973-07-17
Abstract: The varnish is pref. a top coat varnish, and the cutter is pressed to the varnish by a spring; then the cutter is moved relative to the coat of varnish, and the spring pressure is varied. The spring pressure is varied synchronously with the cutter forward movement from an initial to a maximum value; the criterion for the varnish adhesion strength is the distance between the cutter initial position and the point at which a reproducible damage to the varnish coat is done; the initial spring pressure exists only at the moment when the cutter is placed on the varnish; complete removal of the varnish coat is taken as the reproducible damage; the cutter is placed on the varnish at a certain distance from a reference edge of the substrate.

Title: Colour difference generation system - is designed for use at receiving end of electro-optical transmission system
Inventor: DILLENBURGER WOLFGANG DR
IPC: H04N11/14
Filed: 1973-10-08
Abstract: Input chrominance signal is so converted at the sender side, that the colour carrier frequency is a multiple of the horizontal frequency. A reference signal is added to it, whose frequency is twice the colour carrier frequency. A colour carrier frequency signal is obtained from the above by frequency division. Its phase is determined by added horizontal frequency white pulses. The above chrominance signal is separated at the receiving end by a low-pass filter, and the reference signal by a bandpass or a high-pass filter. The chrominance signal with the superposed white pulses is applied to first inputs of two demodulators. The reference signal is converted to a rectangular pulse signal and differentiated.

IPC: D01H4/48
Filed: 1974-03-21
Abstract: The system to prepare a broken yarn end for reinsertion into an open-end spinning chamber, to be spliced into the end of newly-spun yarn, uses a roughened roller which is brought into contact with the yarn to untwist the threads. The mechanical end loosening ensures that yarns of all gauges are opened up to give the same character as the end of the newly-spun yarn for a firm and unobtrusive splice.
Patent DE-2416318-A1 (DE)
Title: Failure monitor for vacuum switch housing
Inventor: MUELLER KURT DR ING
IPC: H01H33/66
Filed: 1974-04-02
Abstract: The failure monitor, for a vacuum switch housing detects leaks in the housing by monitoring the temperature increase of one of the contacts when the switch opens as in 2349019. The variations in temperature are used to alter the physical properties of material attached to the contact and thereby to trigger protection devices. A Heusler alloy may be used: it is connected to a permanent magnet and to the contact and loses its ferromagnetism as temperature increases. The permanent magnet is then released and the protective device to which it was linked by a thread, operates, thermoplastic material may also be used

Title: Vibratory conveyor with superimposed elements - driven from common eccentric shaft via step-wise adjustable rotatable eccentric bushes
IPC: B65G27/32
Filed: 1975-03-08
Abstract: The conveyor is of the type comprising two vibrating elements (2, 3) arranged one above the other, which are supported independently and drives in opposite directions from a common shaft via eccentrics (22, 23) and connecting rods (12, 13). The connecting rods are rotatably connected to eccentric bushes which in turn are secured on eccentric shaft portions of a common drive shaft. The arrangement is such that, by rotational adjustment of the eccentric bushes relative to the common shaft, the effective eccentricities of the connecting rod motions can be varied in steps. The upper element may be a vibratory conveyor sheet with the lower element active as counterweight.
