Title: Thermal cutting
Inventor: PAULEY JOHN THOMAS
IPC: B23K26/14
Filed: 1984-11-19
Abstract: When a sheet (10), e.g. of steel, is cut by a relatively moving, localised energy source such as the laser (3) beads of dross tend to accumulate on opposite sides of the cut on the side of the sheet (10) remote from the energy source (3). This dross subsequently has to be removed in a separate operation, e.g. by milling or grinding. To prevent the accumulation of dross the present invention provides a source (12) of gas under pressure which flows from a nozzle (13) across the underside of the sheet (10). The nozzle (13) remains stationary relative to the cutter (3) whether the sheet (10) moves in the direction of the arrow or whether, in a modification, the sheet (10) is clamped to remain stationary and the cutter (3) and nozzle (13) move in synchronism. <IMAGE>

Title: Hand-held labeler having improved web position sensing and print head control
Inventor: VANDERPOOL JAMES LACY
IPC: B41J2/32
Filed: 1985-03-08
Abstract: A hand-held labeler, e.g. with a thermographic print head, senses the position of the web to control the position of the imprints on the web. A circular indexing member having a plurality of position defining indices provides indications representative of the position of the web. Relative rotation between the circular member and the shaft is prevented by a plurality of key slots or the like disposed on said circular member and engaging a key on the shaft. The angular spacing between the key slots is unequal and is substantially greater than the spacing between the position-defining indices; but the position of the position defining indices relative to the shaft may be adjusted by a distance less than the distance between the position defining indices by bringing a different one of the key slots into engagement with the shaft. The speed of the web-advancing motor is controlled by providing it with an energising pulse, then sampling the amplitude of the back EMF after a predetermined delay following the end of the pulse and, if the sampled amplitude is below a threshold, providing another energising pulse. <IMAGE>
