Title: Process and Apparatus for Producing Crimped Filaments
IPC: D02G1/16
Filed: 1968-08-20
Abstract: 1,198,035. Crimped filaments. ASAHI KASEI KOGYO K.K. 20 Aug., 1968 [23 Aug., 1967], No. 39728/68. Heading B5B. As shown crimped filaments are continuously produced from thermoplastic synthetic filaments crimpable by stretching or by heat treatement after stretching by feeding the extruded unstretched filament from bobbin 1 through rollers 3 and 4 towards a stretching zone provided with a driving roll 5 and associated separate roll 6. Various stretching arrangements can be used such as the combination of a draw pin 7 and draw roll 9 and separate roll 10, or the combination of draw pin 7, hot plate 8 and rolls 9 and 10, or simple cold stretching between rolls moving at different speeds. The stretched filament 21 then passes through ejector 11 and pipe 12 and is blown together with the gaseous fluid supplied to the ejector on to a perforated plate 14 which surrounds a rotatable drum 13, which carries the stretched filament while relaxation, crimping and heat setting are performed. The filament may be heat treated on perforated plate 14 by means 16 and after having travelled through a half circle on drum 13 the filament is wound on to a cone or cheese 19. The crimping and fixing are thus completed while the filament is in a relaxed state on plate 14 which travels at a lower velocity than that at which the stretched filament is introduced into the relaxing zone. The unstretched filament may be a monofilament or a conjugate filament of at least two polymers having different viscosities of different compositions in side by side or eccentric sheathcore arrangements. Examples disclose the crimping of a polypropylene filament, a conjugate filament of nylon 6 and a copolymer of #-caprolactam, nylon 66 and nylon 67 salt, and a conjugate filament of poly(ethylene - diphenoxy ethane 4: 4<SP>1</SP> dicarboxylate) and polyethylene terephthalate.

Abstract: 1,129,517. Voltage measurement. ADVANCE ELECTRONICS Ltd. Dec.2, 1966 [Sept. 17, 1965], No.39761/65. Heading G1U. An arrangement for producing an output representing the true R.M.S. value of an input applied at 10 incorporates an amplifier A 1  to which the input is applied through a variable photo-sensitive resistor R 1 , which enables the gains of the amplifier to be adjusted. The output of the amplifier feeds a heater and thermocouple device T 1  which produces an output which is the R.M.S. of its input, and the output of this is compared with that from a similar, reference, device 72 by a differential amplifier A2. The output from this amplifier operates a lamp which controls the photo-resistor R 1 . R 1  is thereby controlled to vary the amplifier gain so that the same output is always provided from the amplifier The value of R 1  is proportional to the R.M.S. of the input and may be determined by passing a constant D.C. current through the resistor at 12, 10 and measuring the voltage across it using meter M. Capacitors C 1 , C 4 , C 3  &c. isolate the rest of the circuit from the D.C.
