Title: A method of treating polyamide yarn
Inventor: WILLIAMS EBENEZER DAVID
IPC: D02G1/00
Filed: 1966-05-25
Abstract: The extensibility of a bulky yarn composed of crimped continuous filaments of a polyamide, is reduced by applying liquid water to a running length of the yarn at room temperature - e.g. 5-40 DEG C - while the yarn is under a tension of at least 0.02 grams per denier and winding the water-treated yarn under tension into a package, the quantity of water applied to the yarn being at least 50% of the equilibrium content of the filaments at 100% relative humidity as measured at 20 DEG C.  The yarn may be crimped by a plastisizing fluid stream as in Specification 861,108, by false-twisting, or by means of a stuffer-box.  The water, which may contain finishing agents, and anti-static agents may be applied by a spray, felt, dip tank, or grooved applicator. The yarn may be composed of filaments of round trilobal, cruciform, delta-shape, ribbon, or dumb-bell cross-section.  In one embodiment filaments from a spinneret are cooled by an air stream, drawn, passed into a fluid jet in which the filaments are plasticised and which passes the filaments onto a revolving screen-surfaced drum on which the filaments are crimped-set and then sprayed by a lubricant, passed around a pair of rollers several times and then through a groove block applicator to which water is fed at a controlled rate, and then wound up.

Title: Electrical transformer with tap changer system
IPC: H01F27/40
Filed: 1971-04-19
Abstract: 1340356 Transformer tap changing; protection WESTINGHOUSE ELECTRIC CORP 19 April 1971 [16 April 1970] 24192/71 Heading HIT  In a tap changer system a current transformer 72 determines whether current is still flowing through the branch which includes the contact arm to be moved (e.g. arm 22) and if so a protection device stops the drive 90. To change the arm 22 of the tap selector switch 20 from contact C5 to contact C4, the contact 56 of bypass switch 52 is first opened so that the current from arm 22 flows through the vacuum switch 50, which is then opened. A shorting contact 78 is opened next so that if current is still flowing in conductor 57, e.g. due to a fault, a solenoid 80 closes the contacts 86 to stop the drive. If no current is flowing arm 22 is moved to contact C4, then contacts 78, the vacuum switch, and the by-pass switch are closed in turn. The reactor 40 is so wound that when the two arms 22, 24 contact adjacent taps the output voltage will be half way between the two tap values by presenting a high impedance to circulating currents and a low impedance to power current flow. Protective current transformers may also monitor the current flowing to the by-pass switch (Fig. 3A). The protective device (Fig. 2) consists of levers biased by a spring 110 to close contacts 86, but held back by a latch 117 until the solenoid 80 releases it when it is energized. The transformer may be single or polyphase, and either the autotransformer or isolated winding type.

Abstract: 227,082. Western Electric Co., Ltd., (Assignees of Ten Eyck, W. B.). Dec. 31, 1923, [Convention date]. Addition to 203,297. Cores, covering by winding.-A taping machine, particularly designed to wrap magnetic material about a conductor, comprises a serving- head 10, Fig. 1, through which the conductor 12 passes from a guiding-wheel 48 to a capstan 49, and which is rotated in brackets 13 by a chain 15 driven in conjunction with the capstan. The tape 18 is supplied from a spool 17, which is free to rotate about a spindle 19 on the head 10 but retarded by a leather friction band 21, and passes over a guiding wheel 29, Fig. 4, which is angularly adjustable in a housing 25 secured to the head 10, and is wrapped on the conductor by rollers 27, 31. The rollers 27 rotate on pins 26 secured to the housing and the roller 31 rotates on a pin 32 secured to a plate 33 which is pivoted at 34 to the housing. The roller 31 is pressed against the conductor by a spring 36 anchored at 35 to the plate 33 and to a pin 37 which is adjustable in a bracket 42 pivoted at 38 to the housing; a stop 41 limits the turning movement of the bracket. The rollers maintain the conductor straight at the point of application of the tape, and ensure that adjacent convolutions thereof do not overlap. By adjusting the tension of the spring 36 the spacing between the conductor and the tape can be regulated to prevent deleterious strains being set up during subsequent heat treatment of the conductor, which when completed comprises a central wire 45, Fig. 7, strands 46, tape 18, a filling of bitumen 50 and a rubber &c. insulating coating 51. Specification 219,443 is referred to.
