Patent DE-4016398-A1 (DE)
Inventor: CHAUVIN JAQUES DIPL ING
IPC: H04N9/28
Filed: 1990-05-22
Abstract: A focussing device for picture reproduction units is disclosed. In picture reproduction units, such as projection television sets, the electronic beam is not focussed with a uniform quality over the whole surface of the screen. The object of the invention is therefore to ensure a uniform focussing quality over the whole surface of the screen. Voltage values required for optimal focussing are determined for picture points distributed on the screen, then are recorded as digital signals in memories (M) and successively supplied to the focussing electrode of the picture tube (1, 2, 3) during reproduction. The device is particularly useful for focussing in a projection television set.

Title: Bolted joint with elastically deflected flanges - uses elasticity to maintain bolt tension and maintain rigidity of joint
Inventor: BRENDEL HUBERT DR ING
IPC: F16B31/04
Filed: 1991-03-28
Abstract: Two structural elements (18,19) with flanges (13,14) are fastened together with a bolt (15). Small thin strips of metal (11,12,16) are fitted between the joint faces on each side of the bolt. These strips create a gap (17) between the joint faces. When the bolt (15) is tightened, this gap is reduced by the elastic deflection of the flanges (13,14) which causes a corresp. increase in the bolt tension and prevents the bolt from becoming loose so that the rigidity of the joint is maintained in service. USE - Bolted joints.
