Title: A method for controlling an embroidery or sewing machine
Inventor: CONRADS HANS
IPC: D05B21/00
Filed: 1982-07-21
Abstract: A method is for controlling an embroidery or sewing machine having a needle shank and a jump stitch device, which interrupts the movement of the needle shank while its drive continues and the material to be worked is simultaneously conveyed. To shorten the time for an embroidery programme while maintaining low system cost, the machine is driven at constant rotational speed for the needle shank drive and for the material conveying. This speed is referenced to the respective maximum speed of the material for a given limiting stitch length which embraces the major proportion of the stitches concerned. To make stitches of a length exceeding the limiting stitch length, these stitches, are subdivided automatically by inserting a jump stitch having a length corresponding to the limiting stitch length. The constant rotational speed of the machine can be adjusted for each complete machining operation, and is determined for the respective embroidery pattern by analysing the stitch lengths contained in this programme relative to the resultant limiting stitch length. <IMAGE>

Title: Scaffolding
Inventor: FERNANDEZ ANTONIO CAMPOS
IPC: E04G5/06
Filed: 1982-10-22
Abstract: A method of erecting a support bracket (24) and a scaffold structure (10) adjacent an upright member (12) such as a building structure, comprises rigidly attaching the support bracket to the upright member, placing a scaffold structure onto the bracket for support, and fixedly but releasably securing the scaffold structure relative to the upright member by securing means (64) on the bracket. This means that whilst the scaffold structure is being secured to the upright member and when it is removed from the bracket the scaffold is safely supported by the bracket. This prevents the dangerous and unsatisfactory situation of the scaffold structure being supported during attachment and removal from the upright member by a loose anchor bolt. <IMAGE>
