Title: New polyamide yarns
IPC: D01D5/22
Filed: 1968-01-10
Abstract: 1,216,883. Filaments for "mixed shrinkage" yarns. E. I. DU PONT DE NEMOURS & CO. 10 Jan., 1968 [10 Jan., 1967; 12 Sept., 1965], No. 1489/68. Heading B5B. [Also in Divisions C3 and D1] A yarn comprises a plurality of continuous oriented polyamide filaments of two types having a difference in filament length of at least 1% when subjected to boiling water under a load of 4 milligrams per denier, the difference increasing by at least 0À5% when the filaments are further subjected to heat setting for two minutes under a similar load, each filament containing at least 50 mole per cent of repeating units of the formula  where each of the R radicals which may be the same or different is H or CH 3 , x is 1 or 2, and y is an integer from 7 to 14 inclusive. In examples the diamine used was bis-(4-aminocyclohexyl)- methane, and the acid was one with y = 7, 10, or 14. In the preferred embodiment one type of filaments consist essentially of a polyamide having units of the formula while the other filaments comprise a copolyamide having 50-95 mole per cent of the units of the formula and the remaining percentage of units having a different diamine-for example m- and p-xylylene diamine 1,4-aminomethylcyclohexane and other aliphatic, aromatic or cycloaliphatic diamines- or a different dicarboxylic acid-for example iso- and tere-phthalic acid, 1,4-cyclohexyl dicarboxylic, and aliphatic dicarboxylic acids containing 6-16 carbon atoms. Alternatively all the filaments may be of this copolyamide but with one type of filament having 5 mole per cent more of the units of the formula than the other type; or all the filaments may be composed essentially of the units of the formula with the two types of filaments having (a) different numbers of trans-trans, cis-trans, and cic-cis diamino units in the polymer, (b) different relative viscosities, (c) different chain length in the diacid constituent, or (d) orientation indices differing by at least 1À0 (as by being drawn at different temperatures or by varying the filament denier or conditions at extrusion or quenching). The two types of filaments may differ in a plurality of the above ways. The filaments may contain antistatic agents-e.g. nonylphenoxy capped polyethylene ether alcohol-heat and light stabilizers, antioxidants, ultraviolet light absorbers, delustrants, pigments, dyes, and additives to improve dyeability, soil repellence, crease resistance, hand, water repellence, wickability, strength, elongation, elastic modulus, static propensity, or melting point. The two types of filaments may be spun from the same or different spinnerets and have a round, multilobal or shield shape. They may be intermingled by an air jet. The filaments may be hot-i.e. 140-180‹ C.-or cold drawn, and be heat relaxed after drawing to achieve the desired shrinkage in boiling water. The yarn is bulked, when woven or knitted, by being shrunk in a hot scouring operation while relaxed, or by being cold and/or high tension scoured and then heat set under low tension.

Title: Improvements relating to slicing machines
IPC: B26D7/01
Filed: 1934-01-23
Abstract: 432,208. Slicing - machines. FITZPATRICK, H. D., 94, Hope Street, Glasgow.- (Maatschappij Van Berkel's Patent Naamlooze Vennootschap; 33, Boezemsingel, Rotterdam, Holland) Jan. 23, 1934, Nos. 2300 and 12286. [Class 28 (ii)] A substance-holder, for a slicing- machine, of the kind having piercing-members or prongs which are projected into the substance,is associated with means which withdraw the prongs after the last slicing operation to free the last slice or end portion. As shown, the invention is applied to a machine having an orbital rotary knife 11, the substance being fed along an angle-sectioned guide 10 through an opening in the knife casing 12, the slices being received on a tray 18. The substance-holder comprises a body 14 secured to a sleeve 16 which is guided on a rod 17 and carries the feed nut. The prongs 15 are mounted on a yoke 20, provided with a handle 20<1>, secured to a turnable shaft 22 over which a coiled torsion spring is arranged. The spring tends to withdraw the prongs from the substance, but is normally prevented from operating by a detent 26 pivoted at 25 to a bracket 14<1> on the body 14. The pivot 25 is fitted with a torsion spring which tends to keep the detent 26 in its locking position. When the last slicing operation has been effected, the arm 27 on the detent engages an adjustable stop 28 on the casing 12, the detent being thereby raised to permit the prongs to snap back into the inoperative position shown. An ejector may be provided to throw the released slice into its proper position on the tray 18. The ejector comprises a plate 31 guided for longitudinal movement in the front face of the body 14, and springs 34 which tend to move the plate forward as far as is permitted by stops. When the substance is to be clamped, it is pressed against the plate 31 which is thus moved back against the body 14. The plate 31 is held by the prongs 15 when they are projected into the substance. In a modification, the spring on the shaft 22 tends to keep the prongs in the substance, the prongs being withdrawn by a horizontal lever pivoted to the body 14 and engaging an adjustable stop on the casing 12. The lever contacts with a downwardly extending arm on the shaft 22.

[Class 40 (v).] To prevent fading in a receiver the degree of amplification preceding detection is controlled by varying the internal resistance of a valve in accordance with the output from a detecting valve. The controlled valve forms part of the coupling impedance between two successive amplifier valves. The Figure shows a control valve 5 in parallel to the coupling resistance 4 between valves 1, 9. The resistance 8 accentuates the control effected by varying the voltage applied to the grid of the valve 5. The control voltage is obtained from the output of the valve 9 and passes through amplifier 13, detector 14 and direct current amplifiers 15 .. 18 and the resistance 6 in the output of the valve 18 is arranged in the grid circuit of the control valve 5. A circuit 19 of large time constant is included in one of the direct-current amplifiers. Instead of employing triode valves two-grid valves, screened anode valves or multiple electrode valves may be employed and the circuit may be made symmetrical by duplication of the elements.
