Title: Low voltage supply in TV receiver - derived from low flyback transformer with resistor for stabilisation
IPC: H04N3/16
Filed: 1974-06-17
Abstract: The cct is of conventional form, with picture tube extra-high tension and an auxiliary low voltage supply derived via rectifiers from secondary and tertiary on the line output transformer.

Title: Mfg. cores for wooden sandwich panels - by slitting and cutting multiple piece sheet, glueing, pressing, cutting
IPC: B27D1/06
Filed: 1974-09-26
Abstract: Apparatus for making the wooden cores of sandwich panels cuts veneering sheet to lengths of between 1 and 2 metres applies adhesive and stacks and overlaps the pieces to form a continuous sheet, with all the grains aligned longitudinally, passed through a press and subjected to heat and pressure. After drying and cooling, the sheet is slit longitudinally and the slit lengths cut transversely. The cut pieces are then deposited in batches on a cross conveyor, so that the joins are transverse to the direction of travel. The pieces then pass horizontally between guides to pass under an adhesive applicator roller, then pass vertically downwards onto a horizontal conveyor, where they pass through another press for forming into another continuous sheet. This sheet is then cut across again, by a saw for stacking on a table.
