Title: Improvements in or relating to cylinders for circular, independent needle knitting machines
IPC: D04B9/10
Filed: 1949-06-17
Abstract: 664,964. Knitting-machines. HEMPHILL CO. June 17, 1949 [June 24, 1948], No. 16225/49. Class 74 (ii). To assist in guiding the needles of the lower cylinder into their slots in the upper cylinder of a superposed-cylinder machine an extension 6 is provided on the lower end of the upper cylinder and has needle slots 7 in alignment with those in the upper cylinder. The depth of the slots 7 in this extension is equivalent to about half the thickness of the needle stems so that any interference with the needle hook engaging the yarn is avoided. The walls 8 between the slots 7 are bevelled as are also their lower ends so that if one needle is out of line the bevelled edges of the walls 8 tend to direct two needles into the same slot. The shallowness of the slots 7, however, ensure that the intruding needle will be forced out of this slot into its correct one. Specification 536,201 is referred to.

Title: Improvements in electric wave filters
IPC: H03H7/01
Filed: 1922-06-14
Abstract: 202,105. Western Electric Co., Ltd., (Western Electric Co., Inc.). June 14, 1922. Filter circuits.-Circuits that will pass certain bands of frequencies whilst suppressing all other frequencies are composed of impedance elements arranged in the form of a Wheatstone bridge, one pair of diagonal terminals serving as input terminals and the other pair as output terminals, Fig. 17 illustrates the general case in which each arm comprises one impedance element, two of the bridge arms being shown crossed in order that the input and output terminals may appear at opposite ends of the Figure. A mathematical analysis in the Specification shows the effect of varying the values of the impedances in the respective arms as regards the passing or elimination of a single or double band of relatively high or low frequency. The conditions determining the cut-off frequency and the attenuation ratio of the iterative impedances are also given, on the assumption that the ohmic resistance of each arm may be ignored. Figs. 1 to 3 show typical circuits in which the impedances are in the form of tuned circuits L<1>C<1>, L<2>C<2>, L<3>C<3> arranged in series or parallel resonance. In general when B=C, Fig. 17, the circuit passes all frequencies for which the value of A/B-A lies between zero and - 1. On the other hand the circuit acts as a filter when B and C are unequal. When the impedances in both arms of a pair of opposite arms are equal, the corresponding inductances can be wound on the same core, as shown in Fig. 9. As many of the circuits are arranged in tandem as may be necessary to obtain the desired filtering effect, sections having the same cut-off frequency and iterative impedance, but having different frequencies of maximum attenuation or suppression, being preferably employed in combination. Specification 142,115 is referred to.

Patent GB-1083102-A (GB)
Title: Method and apparatus for electroplating articles
IPC: G11B5/64
Filed: 1965-04-21
Abstract: A magnetic metal is plated on to one surface of a web of dielectric material by electrolessly depositing a metallic film on all surfaces of the web and then moving the web through a bath containing an electrolyte, an anode and a cathode at least partially submerged in the electrolyte, the web being maintained in tight contact with the cathode so as to exclude electrolyte from one side of the web. Preferably the web, before being electrolessly plated, is provided with holes which give additional current paths during the electroplating to ensure a more uniform deposit.  The holes may be in lines longitudinally of the web, the plated web being cut along the lines to produce plated webs of lesser width.  The cathodic electrode may be a rotatable drum or it may be a continuously moving conductive ribbon which passes through the plating bath in the form of a parabolic loop round a suitably shaped support.  In the latter modification the ribbon, after being separated from the plated web, may be passed through a stripping bath and a rinsing bath to remove any metal plated thereon, before being returned to the electrolysis bath.  In both modifications the anode in the electrolysis bath has a shape conforming to that of the cathode.  In an example an electroless plating bath for depositing nickel on an elongated polyethylene terephthalate web has the composition .nickel sulphate hexahydrate.18.4 grams/litre .sodium hypophosphite monohydrate.24.4 grams/litre .acetic acid.3.6 grams/litre .sodium acetate.4.8 grams/litre .lactic acid (85%).31.0 grams/litre .sodium succinate hexahydrate.16.2 grams/litre .lead ion.5 p.p.m  The bath is operated at a temperature of 180-210 DEG F. and at a pH of 5.2 \sB 0.6 (adjusted with sodium hydroxide).  The web is previously sensitized with a 30 grams/litre stannous chloride solution containing 10 ml/litre of HCl, and then a 0.1 gram/litre of palladium chloride solution containing 10 ml/litre of HCl to give a thin coat of palladium, with water rinses after each immersion.  Electroplating is carried out in a cobalt sulphate-nickel sulphate bath containing sodium hypophosphite and ammonium chloride and, possibly, saccharin to act as a stress removing ingredient.
