Title: A method of hollow rolling
Inventor: STAAT KARLHANS
IPC: B21B19/04
Filed: 1986-08-22
Abstract: In a method of piercing a solid round billet 6 by rolling it over the plug or piercer 4 of a mandrel 2, the position of the piercer 4 of an adjustably supported mandrel 2 in the roll sizing gap is measured and is kept constant with the aid of regulating means by adjusting the mandrel 2 in dependence on changes in the rolling mill and mandrel geometry. On the assumption that the stress in the mandrel depends upon its strain and therefore upon changes in its geometry, the load on the mandrel 2 can be measured by measuring the pressure in a cylinder 10 acting on the rear end of the mandrel. <IMAGE>

Title: Increasing horizontal bandwidth of weston pal chrominance signals
Inventor: DREWERY JOHN OLIVER
IPC: H04N11/16
Filed: 1991-11-21
Abstract: To increase the horizontal bandwith of the Weston PAL chrominance signal spectrum folding techniques are used. Spectral components with high horizontal frequency and low vertical and/or temporal frequency are carried as components with low horizontal frequency and high vertical and/or temporal frequency. A matrix (120) forms U+V(P) and U-V(M) chrominance signals which are then prefiltered using either rhombic spatial filters or rhombic vertical-temporal filters (122, 124). The two signals are then sampled by sampler (126, 128) which together with switch (136) form U+V samples on alternate lines to the U-V samples. The sampling patterns for the P and M signals are identical but shifted.
