Abstract: 880,502. Winding and reeling wire. VAUGHN MACHINERY CO. April 26, 1960 [July 27, 1959], No. 14632/60. Class 83 (4). A machine for winding wire includes a take-up block arranged to have wire coiled thereabout with the convolutions descending by gravity therefrom, a support for accumulating such convolutions in the form of an upwardly growing package, and means to rotate said support about an upwardly-extending axis that is offset with respect to the axis of the descending convolutions whereby the convolutions are laid in circular progression on said support to form an annular package of outside diameter larger than the diameter of the individual convolutions. Wire W is laid around a fixed take-up block 5 by a flyer assembly 6 rotated therearound and is held against the block 5 by a roller 15 on the flyer 6. The top turns on the block 5 are guided therefrom by a fixed funnel 16 to a fall on to a turn-table 21. Swingable accumulator fingers 19 support the wire coils above the turntable 18 to permit removal of completed coil or package from the turn-table. The turntable 18 is provided with a roller conveyer 20 to facilitate removal of a completed coil supported on a platform 21. In operation the axis of rotation of the turn-table, which is offset from the axis of the take-up block 5, is inclined to the vertical. Three guide rolls 24 parallel to the inclined axis of the turn-table 18 engage the wire convolutions as they are laid on the turn-table 18 which is slowly rotated so that the convolutions form the appropriate form of package or stack, Fig. 2. A wirereceiving drum may be mounted on the turntable. The turn-table 18 may be swung by a pneumatic cylinder 31 to a horizontal position. The turn-table may be in the form of a basket 45, Fig. 4. In a modification, Fig. 5, a turntable 50 has an upstanding core 51 along which convolutions of the wire W descend from a curved horn 52 receiving convolutions from a take-up block having a horizontal axis. A counterweighted finger 24 on the horn allows the wire to drop in hanks of several convolutions at a time on to the turn-table 50 so that said hanks are laid in circular progression thereon. Specification 880,500 is referred to.

Abstract: 1427679 Charge transfer delay circuits ITT INDUSTRIES Inc 5 April 1974 [6 April 1973 14 July 1973] 15235/74 Heading H3U In a bucket brigade circuit, D.C. level drifts are compensated for by feeding to a differential amplifier DV1, the D.C. components of the signals at two spaced apart stages T m , T n  which are controlled by the same clock phase and coupling the amplifier output, or a current proportional to it, to a stage T n-1  preceding the stage T n . Ideally, the two inputs to the amplifier DV1 would be the same, and each stage of the delay would be at a reference potential Um 0 . The output from the amplifier DV1 is accordingly subtracted from a potential of this value derived from a further amplifier DV2 and the difference is applied to the stage T n-1  via capacitor Ck and a switch T d  which is conductive when stage T n-1  is clocked on. The input coupling to the amplifier DV1, transistor T RM , may leave its gate A.C. coupled to the clock line as shown, or Fig. 2, not shown, a D.C. coupling may be used and the transistor connected to the gate of TRM omitted, Fig. 2 (not shown). In an alternative form using p-channel FETs, Fig. 4 (not shown), the output from the amplifier DV1 is used to control a current generator which D.C. couples, to stage T n-1 , a current proportional to the amplifier output. Alternatively n-channel FETs may be used, Fig. 5 (not shown). A further output from the amplifier may also control a second stage further down the line, Fig. 6 (not shown).

Title: Improvements in or relating to telephone systems
IPC: H04Q3/62
Filed: 1925-06-15
Abstract: 236,536. Pollak, J. E., (Siemens & Halske Akt.-Ges.). June 15, 1925. Automatic exchange systems.- In a system in which private branch exchange subscribers themselves set up calls to the main office a switch BW at the P.B.X. responds to the dialled impulses, and in the case of certain combinations of three digits lights particular signal lamps and transfers release-control to the P.B.X. operator. The operator can identify the line that is using a particular trunk, and if the kind of call being made is not permitted to that line, breaks down the connection by means of a key Trt. In the system described, local calls are made over switches (not shown), and the apparatus shown operates in response to the depression of an " exchange " key. Detailed operation. Line relay AR energizes starting relay AN and marks over relays NL, T the terminals of the calling line in the finder banks. When the finder W reaches the line, relays P, T pull up in series with relay NL which is unable to pull up at this stage. Relay T cuts off the line relay and lights the identifying lamp NBL. Belay P lights the lamp BL to mark the trunk busy and extends the calling loop to the impulse relay S which bridges the trunk through the impedance DR and energizes sluggish relay V. Relay P is now locked up over its low-resistance upper winding and contact 12<1>. Dialled impulses are repeated by relav S over the trunk and to the stepping magnet D1 of switch BW. The first impulse of each digit energizes the sluggish relay Z to complete the stepping circuit. As shown, the combinations 231, 232. 233 are allotted to special calls, e.g. calls for a toll operator and telegraph and broadcasting stations. If one of those combinations is received the relapse of relay L at the end of each digit causes the successive energization of relays R1 R2 and one of the relays R3 - - R5. The latter pick out a lamp AL1 - - AL3 to indicate the kind of call in progress and lock up the release relay V over its winding II. On seeing the signal the operator depresses key Flt and thus increases the current through the relay NL sufficiently to operate it and extinguish the lamp NBL, thus identifying the calling line. In the case of a toll call the subscriber hangs up, the operator noting his number so as to know which line to ring when it is ready. If the class of call is not permitted to the particular subscriber the operator breaks it down by means of the key Trt. To release the P.B.X. apparatus, the operator presses key Trt<1> after the subscriber has hung up, whereupon relay V releases relay R1 - - R5, energizes relay B over the off-normal segment to cause the restoration of the switch BW and unlocks relays P, T. The call-finder driving circuit is, however, held open by relay B until the switch BW reaches normal.
