Title: tv vertical synchronisation circuit - is controlled by logic circuit comparing inner and outside synchronisation signals
Inventor: HAFENRICHTER REINHARD ING GRAD
IPC: H04N5/12
Filed: 1979-02-15
Abstract: The digital vertical synchronisation circuit provides indirect sync. pulses even when the video signals are not corresp. to standards. The logic circuit ensures that the internal sync. signals are synchronous with the outside signal. The comparison of signals detects synchronism to switch over to indirect vertical synchronisation. The line counter receives pulses of outside vertical synchronisation with clocking frequency derived from the horizontal deflection oscillator and frequency doubler.

Title: Heat shrink sleeving sealing for cables - utilises shaped interlocking forms in longitudinal edges of sleeving
Inventor: MUELLER SIEGFRIED
IPC: H02G15/18
Filed: 1979-03-14
Abstract: The heat shrink sleeve is for cables or tubes and is wrapped around at the ends which are fixed together by C-shaped forms in the sleeve which interlock. An inner support overcomes difficulties of assembly of earlier methods and provides good retention of the longitudinal edges. A heat shrink sleeve (1a) has C-shaped swellings (4a, 5a) towards the exterior and close to both the longitudinal edges (2a, 3a). The thickness of material is constant including the area of the swellings. A reinforcing strip (7a) is inserted into the smaller swelling. This contains a wire (7c) which allows the material to give good resistance to compression. The smaller swelling is inserted into the larger when the sleeving is wrapped around the sleeved object. An inner section (7b) of the reinforcing strip is surrounded in glue (17) to provide sealing when heat is applied. The combined swellings are compressed by a C-shaped rail (6a).

Title: Distributor for liq. manure - has distributor plate to expand manure stream from pipe elbow to spread it on land
Inventor: MARCHNER SIEGFRIED
IPC: A01C23/00
Filed: 1979-03-19
Abstract: The distributor is for broadcasting pressurised liq. manure from a mobile vessel to both sides or backwards. It consists of a pipe elbow which is connected to the vessel outlet and turns about it. The manure stream emerges from the tapered outlet of the elbow transverse to the direction of travel. An adjustable distributor plate, expands the impinging stream. The distributor plate forms a dish shaped channel transverse to its longitudinal expansion and this meets the orifice edge at a point between its front and rear and on the side of the orifice facing the centre of curvature of the elbow. The curvature of the plate reduces from back to front. The distributor plate can be pivoted on the pivot shaft which is normal to its longitudinal middle plane and runs in the plane of the orifice.
