Patent GB-900343-A (GB)
Title: Improvements in or relating to straight bar knitting machines
Inventor: WOODCOCK HERBERT EDWARD
IPC: D04B11/00
Filed: 1958-09-26
Abstract: 900,343. Knitting-machines. WOODCOCK & SONS Ltd., GEORGE. Sept. 24, 1959 [Sept. 26, 1958], No. 30846/58. Drawings to Specification. Class 74 (2). The inner points of each group of looptransfer points for narrowing and widening on a straight-bar machine are half points and during widening the relationship between these inner points and the needles is such as to effect spreading of the associated loops. During narrowing, however, the relationship is modified so that the half points effectively close the beards of the needles and ensure a complete transfer of the associated loops to adjacent needles in the same way as the normal points. With back racking, therefore, narrowing can be effected down to a particularly narrow width of fabric. The relationship between narrowing and widening can be modified by providing two needle cams one of which serves to maintain a low needle height during widening so that the beards of the needles associated with the half points stay open and the other of which serves to maintain a normal needle height during narrowing whereby the half points effectively close the beards. Alternatively the motion of the narrowing machine can be modified or the position of the half points can be adjusted between a high position for widening and a low position for narrowing.

Title: Method for controlling the advancement of linear elements
IPC: D02H1/00
Filed: 1975-07-24
Abstract: 1516356 Strand break detector; stop motion OWENS CORNING FIBREGLAS CORP 24 July 1975 [29 July 1974] 31008/75 Headings DID and D1F A beam of light is directed onto a continuous linear element advancing along a path such that the light reflected from the element is affected by the speed of the element, the reflected light is detected and converted into a signal which is used to stop the means for advancing the element when the variation in the signal falls below a preset minimum. As disclosed there are a plurality of elements each comprising a glass strand 110, Fig. 1, (not shown) being unwound from the inside of a package 12 and combined to form a roving (30) which is wound to form a package (38). The movement of each strand is monitored by a beam of light and the winding mechanism is shut down, either automatically or by alerting an operator, whenever a preselected number e.g. 2 of the strands are halted through breakage. Alternatively the detectors could be set to register a reduction in speed below a non-zero value. Each strand is withdrawn from its package 12 by passing through the aperture of an annular guide 62 mounted inside the package. The aperture is much larger than the strand diameter and so the strand twists and oscillates during its withdrawal. Light from a bulb (72, Fig. 4) mounted on guide 62 is directed by first optical fibres at the strand. Reflected light is directed by second optical fibres to a light sensitive photo resistor detector 66. If detector 66 never received light it would not conduct, hence capacitor Cl would be charged, transistor 90 caused to conduct and the voltage across capacitor C2 reduced to a fraction of that applied at L@. If detector 66 was permanently lit (e.g. if the strand was stationary) capacitor C1 would be charged transistor 90 switched off and capacitor C2 fully charged. Very rapid intermittent illumination of the detector 66 would charge capacitor C2 to an intermediate voltage. Schmidt trigger 92 is set to fire at a somewhat higher voltage across C2 and will thus provide a signal if the frequency of intermittent illumination (determined) by the speed of advancement of the strand) falls sufficiently. The trigger 92 of each strand detector is periodically tested by the circuit of Fig. 6 and the number of signals counted at counter 110. If the number exceeds the number (e.g. 2) set in decoder 112 a signal is emitted to operate switch 142 to cut the current to roving winding motor M. Circuit 119 prevents switch 142 being operated during start-up.

Abstract: 1,040,327. Copying by scanning. GRETAG A.G. Aug. 8, 1963 [Aug. 23, 1962], No. 31410/63. Heading H4F. An apparatus in which an original 3 is scanned by a cathode-ray tube flying-spot scanner 1 so as to effect photographic reproduction at 6 and in which part of the image light is branched to a photo-multiplier 7 which applies a feed-back signal through an amplifier 8 to modulate the cathode-ray tube grid is characterized by the use of positive feed-back and a total gain around the loop formed of amplifier 8, cathode-ray tube 1, the optical system 2, 4, 5 and original 3 which has a value greater than one for a predetermined transmission value in the transmission range of original 3. As a consequence the apparatus exhibits a bi-stable characteristic, all points in the original which have a transmission greater than the predetermined value driving tube 1 to saturation and producing white and all points which have a transmission less than the predetermined value effectively producing black. According to a feature of the invention the gain of amplifier 8 is varied cyclically as shown in Fig. 2 between the limits A 1  and A 2 . If the cycle period T A  is large in comparison with the scanning time of the total picture a succession of pictures is produced in which the transmission level of the picture elements which produce white progressively varies. If the cycle period is made equal to the time of scanning a picture element each picture element will brighten the tube to white for a part of the element scanning time which depends on the transmission of the element. Thus white, grey and black elements may produce white for the whole, a part and no part respectively of the scanning time. The image is therefore recorded by variable length picture points. The cycle period may also be shorter or longer than the scan period of an element. Reference is also made (without giving specific details) to the use of the invention in apparatus for microscopy, densitometry, radiography, photogrammetry, colour correction and television.
