Title: Method and apparatus for packaging filamentary material
IPC: B65H54/02
Filed: 1963-04-04
Abstract: 977,048. Winding yarns. OWENS-CORNING FIBERGLAS CORPORATION. April 4, 1963 [April 4, 1962], No. 13471/63. Headings DID and D1J. [Also in Division H2] In the winding of a strand on a rotatable collector to form a wound package the strand is held initially by a first guide member adjacent a non-packaging surface of the collector and is wound thereon until the collector reaches its normal speed, is then released from the first guide member and engaged by a traversing thread guide to be distributed over the length of the main packaging surface of the collector. The invention has particular application to the winding of multifilament glass strand since the strand wound in the initial period of acceleration of the packaging surface is not properly attenuated and is, therefore, waste. A multifilament glass strand 28 which is to be wound on a sleeve 26 mounted on a rotatable collet 24 is held initially and for a predetermined period in the position shown by a pin 94 which projects transversely from the end of a rotatable and reciprocable shaft 30. The strand is, therefore, wound on an end portion 24<SP>1</SP> of the collet or alternatively on an end portion of the sleeve 26 while the collet 24 accelerates to its normal speed at which time rotation of the shaft 30 commences, releasing the strand from the pin 94 and causing it to engage with a traversing thread guide 34. In addition to the relatively rapid crossing of the strand convolutions caused by the rotary movement of thread guide 34 the strand is distributed over the length of the sleeve 26 by reciprocatory movement of the shaft 30 under the action of a grooved cam 44. When winding of the package is completed operation of a foot pedal 88 disconnects the drive by slackening the belt 21 and applies a braking action to the collet 24 but (by means of suitable electrical contacts) the reciprocal movement of the shaft is arranged to continue till the shaft 30 reaches the fully extended position shown, i.e. with the thread guide 34 at the end of the sleeve 26 adjacent the non packaging surface. Manual rotation of the shaft 30 may be required to ensure that the pin 94 is in the horizontal position required to guide the strand initially. Motors M 1 , M 2 , M 3  serve respectively to rotate the collet, to rotate the shaft 30 and to reciprocate the shaft 30, and suitable electrical contacts serve to energize motors M 2  and M 3  after predetermined periods from the energizing of motor M 1 .

Filed: 1974-03-27
Abstract: 1436652 Lasers TOKYO SHIBAURA ELECTRIC CO Ltd 27 March 1974 [27 March 1973] 13550/74 Heading H1C In an optical pulse transmission system in which a semi-conductor laser output is determined by pulse code modulated (PCM) signals controlling the excitation current, the inherent delay in laser oscillation build up which occurs when a " 1 " PCM signal follows one or more zero level " 0 " signals is overcome by applying an adjustable compensating pulse to augment the laser output due to this particular " 1 ". In this manner the laser " 1 " response following an " 0 " is boosted and so equalized with that of any " 1 " outputs which may immediately follow. A modulating circuit for a semiconductor laser 7, e.g. a GaAlAs heterostructure, is shown in Fig. 1; the laser producing an output pulse whenever a " 1 " PCM pulse switches on an excitation transistor 6 over a line A and delay 5. The PCM signals are also applied directly and via a delay 1 to respective inputs CP and D of a D-type flip-flop 2. This flip-flop produces an output at Q when the leading edge of a pulse is present at input CP while an input D is zero, this output ceasing when input D is present. The Q output is combined with the PCM signal currently received in an AND gate 3, and if this signal is a " 1 " and the previous signal " 0 " a compensating pulse is applied to the laser through transistor 4 to augment the excitation current through transistor 6. In a modification, Fig. 3, a compensating pulse may be obtained selectively when two or more " 0 "s precede a " 1 " signal. In this arrangement D-type flipflops 10-1 to 10-n form a counter driven by a clock pulse source 11, the order of the flip-flops 10-1, 10-2 etc. corresponding to the number of " 0 "s required to precede a " 1 ". The outputs Q 1  to Q n  control through a NOR gate 14 a transistor 15 which injects a compensating pulse in the excitation circuit of laser 20, the output of Q 2  being applied to the gate through an inverter 12, while the outputs Q 3  to Q n  are applied through NOR gates 13 1  to 13 n-2  individually operative when associated switches S 1  to S n-2  are turned off.

Abstract: 599,928. Soldering; soldered joints. WURZBURGER,P. D. May 30, 1945, No. 13599. [Class 83 (iv)] [Also in Group XXVIII] A fitting for a capillary joint, Figs. 1, 2, having a socket 2 for receiving telescopically a tube 3 with a capillary space C therebetween, has a thickened rib portion 4 formed on the said socket wall to provide a zone of greater heat capacity than the unribbed wall to assist in the melting and running into the capillary space of the bonding material. The ribs which terminate at the open end of the socket may, alternatively, be of semicircular or V-form. In a further modification, Figs. 10, 11, a slot 92 is provided, which terminates in the rib 91, so that a greater area of contact is obtained between the solder rod or other bonding material and the heat reservoir 91. The end of the socket is chamfered at 93 to accelerate local cooling and hence prevent the flow of bonding material beyond the end of the socket. In another modification, the heat reservoir is of annular form and is spaced back from the open end of the socket and the aforesaid slot terminates in the said annular rib. In a further modification, the outer end of the socket is counter-bored to prevent the flow of bonding material beyond the said outer end. In another form, Figs. 22, 23, a slot 160A is made in the rib 170 to accommodate a solder rod. An internal chamfer mav also be included on the end of the socket for this purpose. In a modification, the longitudinal rib terminates in an annular rib at a small distance from the open end of the socket. In a further modifica - tion, a lateral hole may be drilled through the longitudinal or circumferential ribs to accommodate the solder rod, or a circular boss on the socket, acting as a heat reservoir, may be drilled for this purpose,

[Also in Group XL (c)] A stud switch comprises two separable portions one of which has a rotatable shaft to which a knob may be secured and means enabling it to be secured to a mounting panel and the other of which houses the electrically-adjustable elements of the switch and a rotatable shaft whereby they may be adjusted, means being provided whereby the two portions may be releasably secured together with their shafts in engagement so that rotation of the shaft of the first-mentioned portion effects adjustment of the unit. The front portion 1 of the switch is secured to a panel 6 by means of a threaded portion 4 and a nut 7 and is provided with a shaft 8 and a detent mechanism comprising a toothed wheel 9 and a spring-loaded ball 10 so that the shaft may be made to assume any one of a number of angular settings. The rear portion 2 comprises a housing having studs 19 mounted on the front and back surfaces thereof. Spring-metal brushes 20 attached to rotatable shaft 22 make contact with the studs 19; a further pair of brushes 34 make contact with annular metal rings mounted on the same surfaces as the studs 19. The rear portion 2 is provided with an annular flange 29 which fits within an annular recess 28 in the front portion 1; the two portions are then held together by an internally-threaded ring 30 which screws on to an external screw-thread on the front portion 1. The ends of the shafts 8 and 22 are so shaped that they engage when the portions 1 and 2 are secured together so that rotation of the shaft 8 causes the brushes 20 to rotate over the studs 19. The studs and brushes at the rear surface of the portion 2 are covered by a detachable dust cap 25. Thus the portion 2 containing the electrically-operative components of the unit may be readily detached from the apparatus in which it is used, even when it is in service, for cleaning. Long flexible leads are used so that there is no need to break the electrical connections.

Filed: 1970-03-23
Abstract: 1,249,274. Electromagnetic testing. FORD MOTOR CO. Ltd. March 23, 1970 [April 3, 1969], No. 13915/70. Heading GIN. To determine electromagnetically the mechanical properties of a moving strip of sheet steel it passes through a magnetic field that magnetizes it to effective saturation first in one direction and then in the other. Sensing coils measure the flux change produced by passing from one remanent magnetization to the other and this flux change is halved to give the flux change necessary to reach a computed zero value of magnetization. The applied field necessary to return the magnetization in the sheet to the computed zero value represents the coercive force of the sheet, which is proportional to various mechanical properties of the steel such as the tensile strength. Alternatively instead of using remanent magnetization to compute the zero value, the sensing coils can be located within the applied magnetic field and the flux change produced by passing between the magnetization at saturation can be used. D. C. magnetization may be used but preferably low frequency A. C. magnetization is employed, with digital monitoring. As shown Fig. 7 the strip passes through a detector coil 22a below a series bucking coil 20a to cancel direct induction from the surrounding magnetizing coil 18a The instantaneous magnetizing current detected by series resistor is gated at the "zero" of the cycle by a Sample + Hold circuit 68. The zero point is computed by converting the detector-coil voltage to a frequency which is fed (i) to an UP-DOWN counter 76 and (ii) through a divide-by-two flip-flop to store 78 or 80. Digital comparator 82 determines when the count-down equals that in the store (i. e. the mid or zero point of the cycle) to trigger the Sample + Hold circuit. Voltage reversal in the bucking-coil 20o when the strip saturates operates the reset and counterstore-switch.
