Abstract: 1,258,452. Non-woven fabrics; knitting. WIRKMASCHINENBAU KARL-MARX-STADT VEB. 24 March, 1969, No. 15322/69. Headings D1C, D1K and D1R. A textile fabric comprises a fibrous material 5 enclosed in a plurality of parallel longitudinally extending rows of chain stitches or in a warp knitting wherein beneath each warp thread loop 3 on the surface of the fabric there is a loop or loop like formation 4 of fibres with the legs of each loop 4 extending through the head of a prior warp thread loop 3. Laddering is limited because the fibre loops bunch up in the warp thread loops if the latter are pulled out. The fabric may be made in a sewing-knitting machine in which horizontal needles 13 having hooks 25 closable by slides 12 cooperate with thread guide 14 to form the warp thread loops 3 and also engage fibres of the material 5 to form the loops 4. During needling the material 5 is supported by a retaining bar 15 having pins 16 and a stripping comb 17. The fibres are congested at 5' by means of an abutment member 18 which is adjustable transversely, between bar 15 and comb 17 and heightwise a support 19 provides an abutment for pins 16.

Abstract: 1289747 Capacitors INTERNATIONAL STANDARD ELECTRIC CORP 2 Sept 1970 [8 Sept 1969] 41993/70 Heading H1M Prior to hermetically sealing the housing enclosing a vacuum capacitor, the assembly is heated to a temperature at which gases adsorbed on the electrodes and internal surfaces are released, the housing is evacuated, the temperature is reduced to below the outgassing temperature, a gas inert to the electrodes is introduced until the pressure is about 10<SP>-3</SP> Torr, and an alternating voltage is applied between the electrodes. The amount of inert gas introduced is such that it is substantially completely adsorbed on the electrodes any free gas being insignificant. The housing may be evacuated again before sealing, but below the outgassing temperature. Preferably the voltage, which may be A.C. or D.C. with reversing polarity, is such as to cause arcing not more than once in five seconds and is raised to a maximum of 1000 to 1500 volts per mil. of electrode spacing. The adsorbed gas is released locally and ionized where a breakdown occurs in use and provides the means for self-repair of the defect. As shown a fixed vacuum capacitor comprises insulating sleeve 14 with end plates 12, 13 each supporting sets of concentric cylindrical electrodes 17, 18, but it may also be variable and the electrodes may be flat, groove or spiral.

The carrier 21 now moves toward the guiding frame 13 until it abuts the second microswitch 38 whereupon the tube is cut and folded and secured e.g. by staples, by the device 26, 27. The carrier 21 then moves towards the frame 13 until the open end of the tube is located around the outer ends of plates 15 carried by the frame 13. The ram 12 then commences the second stage of its movement to push the roll into the packing tube, the open end of which is then removed from the clamps 23, 23 and sealed e.g. by a hand stapler. A table top 19 is finally tilted sideways to tip the packaged roll on to a conveyer not shown. The guillotine device 26 may be replaced by a rotary cutting device or, if the packing tube is of plastics, by a heatsealing device. Also, in the case of plastics tubing the photo-electric cells 41 may be replaced by sonic cells. The mechanical ram 21 may be replaced by a pneumatic ram, and the plates 15 may be of arcuate shape.
