Title: Continuous winding of filaments
Inventor: SCHULLER WOLFGANG
IPC: B65H67/048
Filed: 1960-11-25
Abstract: 1,012,166. Winding. W. H. W. SCHULLER. Nov 20, 1961 [Nov 25, 1960], No. 40666/60. Heading D1D. A method of continuously winding filament or strands of glass fibres comprises moving a full bobbin rotating at normal winding speed away from its winding position and into an unloading position, moving an empty bobbin rotating at normal winding speed away from an unloading position and towards the winding position, halting the empty bobbin after it has passed the winding position so that the emempty bobbin crosses the path of the filament being wound, decreasing the rotational speed of the full bobbin so that the length of filament between the full and empty bobbins is broken, and moving the empty bobbin into the winding position. As shown, bobbin 10 in the winding position and bobbin 12 in the bobbin exchanging position, are mounted in a drum 20 rotatable about its axis by a motor 22 and the bobbins are drivable by motors 13, 14. Before a wind begins the filament 1 passes over a traverse 9, about the bobbin 10 and on toapre-winding drum 11 until the desired thickness of filament is obtained; the wind on bobbin 10 is then begun. When the bobbin 10 is full the drum 20 is rotated in direction A through approximately ¥ of a revolution so that the yarn becomes partially wrapped about empty bobbin 12 rotation of which begins simultaneously with the rotation of durm 20; at the same time bobbin 10 is slowed and subsequently the filament between the bobbins breaks so that winding continues on bobbin 12. Drum 20 is then rotated through “ revolution in direction B to bring bobbin 12 into the position of bobbin 10 shown in Fig 3. Full bobbin 10 is then replaces by an empty one. To ensure that filament of varying thickness is not wound on to the package the traverse 9 is displaced at the beginning of winding and at changover of bobbins so that the filament then delivered is would on to a special end portion of the bobbin from which it may be removed when the bobbin is doffed. Each bobbin may be provided with its own guide which may be cleared when the associated bobbin is in the doffing position. In another embodiment the pair of bobbins is moved along straight paths which intersect at right angles to achieve the same effects as above. In this case the movement of the bobbins may be controlled by hand or mechanically or it may be time-controlled or controlled by movement of the filament.

Filed: 1976-09-30
Abstract: 1529269 Distinguishing between data and noise INTERNATIONAL BUSINESS MACHINES CORP 30 Sept 1976 [28 Nov 1975] 40693/76 Heading H4P To discriminate between data and noise in a carrier frequency transmission system, the data signalling period being T, narrow band signals at the extremes f 1  ,f 2  of the passband are filtered out, added together, the sum being sampled at the rate 1/T, at N different phases {corresponding to delays O, T/N . . . C - DT/N}, the energies {i.e. integrated squared values} of the sampled signals being compared. In the presence of noise only, all the results are equal, but, should data be present, a maximum energy significantly greater than a minimum energy occurs in the set of results. Logic 41 gives an output if the greatest energy is greater than y (γ = 4) times the least energy, to indicate the presence of data. Incoming data on line 1 is sampled at a rate m/T (m = 6) and passed to known digital filters 4, 5 after a/d conversion at 3, the filter outputs being summed at 6 and passed to shift register delay line 7, whose tappings 8-13 provide the N different phase signals, sampling at the rate 1/T taking place either at 14-19, or at the input to delay line 7. The sampled signals are squared by multipliers 20-25 and digitally integrated at 26-31. The decision logic 41 comprises two cascades (42-46; 47-51), Fig. 3A (not shown) of "greatest", and "least" comparators, respectively, the extracted least signal (Emin) being multiplied by y at (52), comparator (53) giving an output whenever Emax > yEmin, to indicate the presence of data. The digital filters, and "greatest" and "least" comparators are detailed in Figs. 4,3B, 3C (not shown).

Abstract: 1,240,684. Multipliers. HONEYWELL Inc. 28 Aug., 1968 [19 Sept., 1967], No. 41071/68. Heading G4G. [Also in Divisions H3A and H3T] A multiplying arrangement comprises first and second differential amplifiers, i.e. transistors 102, 118 and 132, 134 respectively with their outputs paralleled; a signal input is applied from terminal 100 and is applied to the inverting input of the first amplifier, i.e. to transistor 102 and also to the non-inverting input of the second amplifier, i.e. via resistor 130 to transistor 132. Negative feedback is applied from the output terminal 110 to the inverting input of the first amplifier, i.e. to transistor 118 and also to the non-inverting input of the second amplifier, i.e. via resistor 144 to transistor 132. In a first embodiment (Fig. 1, not shown), transistors 102, 118 are coupled by a resistor (24), diode 120 of Fig. 3 being replaced by a short-circuit and diodes 128, 140 omitted, while transistors 132, 134 are coupled by a resistor 138, diode 136 being replaced by a short circuit. This embodiment gives an output the sign of which is independent of the sign of the input, since if a positive input is applied to terminal 100, transistors 102, 132 become conductive, conduction in transistor 132 biasing transistor 134 non-conductive, so that an inverted signal is applied to transistor 106 from transistor 102. If, however, a negative input is applied to terminal 100, transistor 102 is biased non-conductive and a non-inverted signal is applied to transistor 106 from transistor 134. In a second embodiment, squarewave switching signals are applied in opposite phase to terminals 126, 142; these switch the two differential amplifiers alternately into circuit. The output then comprises a square wave, the phase of which changes 180 degrees when the input at terminal 100 changes sign. The arrangement may be used as a fourquadrant multiplier.
