Title: Improvements in and relating to the production of lace, net and the like
IPC: D06M15/333
Filed: 1941-08-29
Abstract: 552,190. Making lace from nylon yarn. BRITISH NYLON SPINNERS, Ltd., and LOASBY, G. Aug. 29, 1941, No. 11041. [Class 15 (ii)] [Also in Group V] In the manufacture of lace from nylon yarn in lace-making machines wherein the bobbins carrying the yarn are lubricated by graphite, a coating of size, gum, or resin is applied to the yarn prior to its use and subsequently removed by scouring together with any graphite which may have adhered to the yarn. The coating may either be a water soluble size or an emulsion of an insoluble size, and a small quantity of a softening agent such as an oil may be added. Sizes mentioned include starches, gelatine, naturally occurring gums, watersoluble resins of the methyl methacrylate or polyvinyl types, or resins of those types which are insoluble in water. The quantity of size may amount to 15 per cent. of the weight of the yarn. In an example, nylon yarn is treated with a water solution of polyvinyl alcohol or partially saponified polyvinyl acetate and such that 4 to 5 per cent. of the polyvinyl compound is incorporated with the yarn after drying. It is then treated with sulphonated tea-seed oil to put a further 2 to 3 per cent. on the weight of the yarn. After passing through the lacemaking machine, a simple scouring is sufficient to remove the coating together with any graphite which may have adhered to the yarn. Specifications 461,236 and 461,237 are referred to.

Title: Improvements in or relating to signal mixing arrangements
Inventor: FENTON ROGER WAKEFIELD
IPC: H04N5/275
Filed: 1967-03-09
Abstract: 1,142,408. Television. MARCONI CO. Ltd. 1 Dec., 1967 [9 March, 1967], No. 11108/67. Heading H4F. A video signal mixer arrangement for supplying, in desired controllable proportions, input signals from a plurality of sources, e.g. A and B, Fig. 2, to a common output terminal O, comprises signal sampling switches TA, TB and switch operating means, e.g. bi-stable device BS, for sequentially operating the sampling switches at a frequency which is at least twice the highest input signal frequency, only one switch being closed at any one time and the proportion of the total time during which each switch is closed being adjustable. The arrangement also includes a low-pass filter F for excluding the switching frequency from output terminal O. A D.C. component may be added to the video signals to be mixed so that switches TA and TB may be of the unilateral type instead of the bilateral type, Figs. 4 and 5 (not shown). The ratio of the mixture of the input signals contributing to the output is controllable by controlling the mark-space ratio of the bi-stable BS. When switch T12 is moved into its other position, the sampling switches TA and TB are operated by a pattern generator W controlled by television synchronizing signals at terminal TVS and a " wiping " operation is produced by feeding the input signals alternately to the output at a desired frequency so that for a desired proportion of a scanning line or field period one signal is connected to the output and for another portion of the time the other signal is so connected, e.g. a corner of one picture may be replaced by another picture. " Cutting ", i.e. replacing one signal which is fed to the output by another, is effected by means of a further switch (T3, Fig. 6, not shown) which applies a suitable D.C. bias potential to a selected sampling switch. In the embodiment described with reference to Fig. 6 (not shown), a plurality of signals are " mixed," " wiped " or " cut " as required, the arrangement including a corresponding number of sampling switches. Signals from more than two sources may be mixed by providing the same number of sampling switches and closing them in succession one at a time, the driving means having the same number of stable states as there are switches and being controllable to permit the relative periods of closures of the individual switches to be adjusted.
