Patent GB-2092185-A (GB)
Title: Knitting process and machine
IPC: D04B39/00
Filed: 1982-01-28
Abstract: In a knitting technique in which opposed threaded needles NL, NR reciprocate towards and past one another in a time-varying motion which is at least principally lengthwise of the needle, one needle approaches and picks up a yarn-end from another needle and forms a loop in the yarn and over the one needle while the other needle withdraws. The other needle then approaches in its turn to pick up a yarn-end and form a further loop while the one needle sheds its loop on to the yarn-end now picked up to form the further loop, the cycle continuing to produce a seam of linked loops. Shogging action by needles and/or associated yarn- control elements produces seam interaction to link seams weft-wise as a knitted fabric. More complex interaction produces patterned fabrics and other knits where yarns link across several wales. An apparatus to carry out the technique includes a needle motion drive using linkages to produce a durable and precise drive action. <IMAGE>

Title: Controlling packaging machines in response to the supply of articles
Inventor: HERTRICH WOLFGANG
IPC: B65G47/72
Filed: 1983-05-26
Abstract: In packaging machine equipment, objects to be packaged are fed to one of a number of packaging machines 22, 24 or 26 by way of a rotary distributor 10. The packaging machines 22, 24, 26 each have their own regulable drive motors 28. An angle detector 34 is provided for monitoring the rotary movement of the rotary distributor 10 and further angle detectors 36 are associated with each of the packaging machines 22, 24 and 26. The signals from the angle detectors 34 and 36 are fed to a control means 32, which in turn controls the drive motors 28. Thus, perfect synchronisation can be achieved. No means for storing the objects are required, and in the event of a packaging machine 22, 24 or 26 becoming inoperative, the remaining machines can maintain operations without the need for additional conveying means and the deflecting and transfer devices associated therewith. The objects are therefore handled in the best possible way and do not suffer damage. <IMAGE>
Patent GB-2121969-A (GB)
Title: Tachogenerators
Inventor: DANIELS ARTHUR RICHARDS
IPC: G01P3/486
Filed: 1983-06-15
Abstract: A rotary tachogenerator giving a rippled d.c. voltage output from commutator COM has a sampling arrangement to select samples of the output voltage away from polarity reversals and produce from the samples a voltage output proportional to speed with a reduced ripple component. This is achieved using a rotary optical sensing disc SD mounted in rotary synchronism with the commutator and operating in conjunction with an LED and photo- transistor SDS to control a sampling circuit TSS so that sampling of the output voltage occurs only near the peaks of the rippled output. Further reduction of ripple, particularly at the low-speed end of a measuring range, is achieved by electronically increasing the sampling rate to take several samples between each pair of sequential reversals. <IMAGE>
