Filed: 1975-05-23
Abstract: 1470680 Capacitors; filter assemblies ERIE ELECTRONICS Ltd 23 May 1975 [22 Aug 1974] 36969/74 Headings H1M and H1R In a filter capacitor comprising electrode foil strips and dielectric strips wound into a roll and a lead-through conductor passing through the centre of the roll, one of the electrode strips is electrically connected to the lead-through conductor, and the other to the cylindrical metallic casing of the capacitor, securing means is provided for mechanically and electrically connecting the container to a chassis or bulkhead having an aperture through which the container can pass, and the electrical connection between the other electrode foil and the container, or between the securing means and the container, or both, being based on pressure contact only. In a method of manufacture, the electrode foils are staggered so as to extend from opposite ends of the roll, and two short foil strips are incorporated in the winding, in contact with respective electrode foils, their length substantially corresponding to the circumference of the roll at their location. After drying and impregnation one short foil strip 5 (Fig. 2a) and its associated electrode foil are compressed on to central conductor 7 and soldered to it. The other short foil 6, previously slit has its slit ends splayed outwardly, an insulating member having a tube fixing into the central aperture, then an end cap 12 (Fig. 3a). The roll is slid into aluminium can 13 until the end cap abuts a rill 14 splayed ends 8 being thereby pressed against the can 13 and making secure electrical connection therewith. An end cap is then slid on to the opposite end of the roll, and the two ends of the can are spun over the end caps. To mount the capacitor on bulkhead or chassis 20 (Fig. 5), a circlip 16 is mounted in a groove 14 and a locking washer 17 with a tapering surface engages the circlip whereby by tightening nuts and bolts, the capacitor is securely mounted by pressure contact only. Optionally (Fig. 6, not shown), a second, plain, washer may abut the opposite surface of the chassis 20. Lead-through conductor 7 may have ferrite beads thereon to provide an L-type filter. In a modification (Fig. 8d) a laminated insulating closure disc 32 is held on threaded brass lead 31 by plate 30 and bolt 33. Wound capacitor element 34 constructed as illustrated in Fig. 2a is mounted on the wire with insulating sleeve 35 over the capacitor element 34 and plate 10 which engages projecting foil 5 and the associated electrode. The unit is inserted into aluminium can 36 until end cap 32 abuts a rill 37, a second laminated end cap 38 is inserted from the other end, trapping splayed ends 8 of foil 6 against can 36. The assembly is secured by nut 39 and the can ends are spun over. The capacitor is mounted on a bulkhead or chassis as previously described.

In one form, Fig. 1, a bracket 14 adjustably fixed to the post 10 by pins 24, 38 mounts two pulleys 16 for a chain 33 which anchors the post and passes over a third pulley 28 at the top of the post. The top pulley is raised by hydraulic jacks 19 to tension the chain. A buffer, Fig. 3 (not shown), fits in sockets 51, and the apparatus may be moved on two wheels 41 and an adjustable wheel 42. After removal of either or both sleeves 22, 23, the bracket 14 may be repositioned on the post with the assistance of a winch (27), Fig. 2 (not shown), on the other side of the post. A hook or gripper on the chain engages the part to be straightened, and increased force may be applied by replacing the left-hand pulley 16 by a pair of pulleys and a floating pulley between the pair and the chassis to be straightened. The chain 33 passes around the pair of pulleys and the floating pulley and is attached to a point 45 on a lower bracket 46, an additional chain attaching the floating pulley to the chassis. Instead of anchoring the post by means of the chain 33, it may be anchored by a chain attached to the bracket 46 or a reel 40.

The monofilament yarn used is preferably nylon 6 or nylon 6,6. The yarn produced by the above method is stated to be especially suitable for the manufacture of stretch hosiery, the yarn possessing properties which enhance the setting of hosiery in boarding treatments. Such a property is the Boardability Factor, which is defined in the specification. The yarn is characterised by having a Boardability Factor less than 2, preferably 1-2, and most preferably 1-1.5. Another such property is the twist liveliness defined as the product of torque and denier of the yarn.

Abstract: 339,117. Smith, W. Prince-, and Waterhouse, D. Dec. 7, 1929. Doffing-arrangements; thread-holding arrangements.-In a flyer spinning or analogous machine provided with mechanical doffing apparatus and having means for aligning the flyers prior to the doffing operation and a series of angularly movable prongs adapted to control the threads during the manipulation of the full bobbins, the prongs are adapted to seize and retain the threads and to function in association with thread-severing means and thread-guiding and controlling means to cause the severed threads to become correctly wrapped on the empty bobbins when these are exchanged for the full bobbins. The invention is shown applied to a machine having the doffing apparatus described in Specification 220,835 and the prongs p are mounted in pairs behind each flyer on a rotatable shaft o, each prong having a hooked end p<2> and carrying a slidable, weight p<3>; the shaft o also carries; a horizontal bar s extending the length of the machine, and which bar, with a horizontal rod r supported on the rail C, forms the thread-guiding and controlling means. After the full bobbins c have been lowered over the transfer pegs on the cranked brackets l, Fig. 2, the shaft o is rotated counterclockwise through 360‹ so that the prongs sweep through the legs of the aligned flyers and engage the threads T, the weights p, as the prongs approach the spinning position shown in Fig. 4, sliding down the prongs and nipping the threads in the hooked ends p<2>; the threads are then severed by a cutter bar q and the severed ends are held under tension by the members p<2>, p<3>. The empty bobbins d are then moved below the spindle a and raised by the lifter rail on to the spindles and the rod r is raised to nip the severed threads against the bar s which is now stationary. After the brackets ! l have been moved outwards to the full extent and the fiveraligning means has been withdrawn, the machine is re-started, the threads being drawn from between the members p<2>, p<3> and guided correctly on to the empty bobbins by the members r, s which hold the loose ends under tension until they are correctly wrapped upon the bobbin.

Title: Recording devices, such as oscillographs

Abstract: 1,121,406. Pulse circuits. SIEMENS A.G. 23 Aug., 1966 [23 Aug., 1965], No. 37845/66. Heading H3P. A circuit for processing input signals into trigger pulses suitable for triggering the time base of an oscilloscope comprises a pair of parallel channels A, B, having specified components. As described, each voltage-sensitive gate 2, 3 is responsive to bipolar pulses greater than a minimum threshold in one position of switches U2, U3 and to monopolar pulses in the other setting of U2, U3. Blocks 2, 3 may be formed by differential amplifiers having their thresholds controlled by potentiometers P2, P3 and switch S. Shaping circuits 6, 7 provide a pulse each time the input signal to the appropriate gate 2, 3 reaches an upper or lower threshold level. The circuit has four different modes of operation dependent on the settings of switches S1 ... S4 as shown in Fig. 2. When it is desired to examine only a part of a waveform, switches S1, S4 are closed and an auxiliary output from the circuit fed as intensity modulation to the grid of the cathode-ray tube. A bright marker spot will thus be visible on the tube and may be adjusted by control t v  of delay device 1 so as to coincide with the interesting part of the waveform. Switch S1 is now opened and S3 closed so the time base will then start at the point selected by t v . The time base may alternatively be triggered in a " range-dependent " manner, i.e. only by input signals within upper and lower limits determined by threshold gates 2, 3 by closing switches S2, S. Bi-stable circuit 4 is set by a pulse derived when the input voltage passes a lower threshold, initiating operation of the delay device 1. If the input voltage exceeds an upper threshold, a second pulse from 6 or 7 resets the bi-stable device 4 and inhibits any output from 1.
