Abstract: 1,270,495. Separating dirt from fibres. SCHUBERT & SALZER MASCHINENFABRIK A.G. 17 March, 1970 [20 March, 1969; 30 April, 1969], No. 12834/70. Heading B2H. [Also in Division D1] Dirt - laden fibres are fed to a spinning device 7 along a path having two portions set at an angle to each other so as to produce a change in the direction of movement of the fibres and to throw out dirt particles through a separating opening 6 at adjacent ends of the two portions of the path. As shown, dirt-laden fibre supply 5 is separated into individual fibres by toothed roller 2. These fibres are transported past the separating opening along a curved path and the dirt particles are thrown into collecting space 5 from where they are removed. An air current via duct 4 flows in the opposite direction to the separated dirt particles to keep the fibres flowing behind the separating edge 3. The angle between the adjustable separating edge 3 and a radius of roller 2 is preferably at least 30‹. The fibres are normally spun in device 7 but when spinning is to be discontinued the fibres can be fed through the separating opening instead of to the spinning device 7. In alternative embodiments: An additional air stream can be introduced immediately upstream of the separating opening (Fig. 4, 5, 6, 12, 13). The separating edge 3 can be curved or flattened (Figs. 2 and 3). The fibres can be passed along straight or curved duct portions at an angle to each other (Figs. 5, 6, 12, 13). The separating opening can be closed by a closure part when clean fibres are being spun (Figs. 7-13, parts 8, 83, 86 and 54). A plurality of spinning units may have ganged control for adjustment and dirt removal.

Title: Improvements in or relating to band-pass filters
IPC: H03H7/01
Filed: 1954-05-04
Abstract: 782,676. Band-pass filters. SABA SCHWARZWAELDER APPARATE-BAU-ANSTALT A. SCHWER SOEHNE GES. May 4, 1954 [May 4, 1953], No. 12892/54. Class 40 (8). A band-pass coupling comprises at least two coupled resonant circuits and is characterized in that at least two compensation voltages are added to its output voltage in order to obtain two symmetrical zero-response positions. In the circuit of Fig. 2 the inductively coupled circuits 1, 2 are further coupled by means of coupling coils 4, 5 in series with a variable resistance 6 to provide a first compensating voltage. A further compensation voltage is derived from a coupling coil 7 and variable resistance 8. The zero response positions can be adjusted by means of the variable resistances 6, 8. In the arrangement of Fig. 3 three resonant circuits 1, 2, 3 are coupled inductively and the output applied to a diode 10. A first compensation voltage is derived from coupling coil 14 and is applied to the cathode of the diode. The second compensation voltage is derived from coupling coil 15, undergoes a 90 degree phaseshift in the circuit 16, 17, 18 and is applied to the anode of the diode. The centre-tapped output circuit 3 is neutralized with respect to the phase-shift circuit 16, 17, 18 by means of the equalizing capacitance 11. The zero response positions are balanced by adjustment of the couplings k1, k2 or the coupling coils 14, 15.

Title: Optical card reader
Filed: 1962-04-04
Abstract: 973,118. Sensing record cards. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 4, 1962 [April 14, 1961], No. 12897/62. Heading G4M. A perforated record card is sensed columnby-column by energizing neon lamps L1-L80 in sequence, photoconductive strips PC1-PC12, one for each row of the card, providing output signals representing the recorded data and also controlling the energization of lamps L1-L80 in such a way that if any column of the card is not perforated, the next lamp in the sequence is energized after a shorter time interval than the normal decay period of strips PC1-PC12 or the normal extinction period of lamps L1-L80. Each lamp L1-L80 is provided with a lucite light guide 46 and is pulsed on by the corresponding monostable circuit D1-D80 triggered by the associated stage of a ring counter 9. A start pulse at terminal 42 pulses lamp L1, and if one or more holes are present in the first column of the card an output is obtained from OR gate 35 to trigger commutator 16 which then scans the strips PC1-PC12 to produce a differentially-timed pulse (or pulses) on lead 18. The output of OR gate 35 also inhibits gate 38 to prevent the start pulse, which has been delayed by network 32, from stepping on the ring counter 9 through OR gate 31. At the completion of a scan, commutator 16 pulses lead 17, and after a suitable delay introduced by network 34, the next lamp L2 is pulsed on. If there are no holes in a column, no output is obtained from OR gate 35, commutator 16 is not triggered and gate 38 is not inhibited, so that the pulse which initiated energization of the corresponding lamp, after passing through network 32, is recirculated and causes the next lamp to be energized. The output of strips PC1-PC12 may be taken directly from amplifiers 14, in which case commutator 16 is omitted, line 15 is connected to line 17 and delay 34 suitably adjusted to account for the decay time of the strips of the extinction time of the lamps.
