Abstract: 1523234 Endless conveyer systems MARDON SON & HALL Ltd 22 March 1977 [23 March 1976] 11576/76 Heading B8A Normally articles placed in compartments 17 of conveyers 14, are conveyed side-by-side in pairs on to respective conveyers 15, 16. They then pass via slide members 20, 21 to a shoot 24 common to the two lanes. Conveyers 35, 36, then feed the articles into a container 11 on a conveyer belt 37. When a sensor 43 or 44 recognizes that a compartment 17 of the respective conveyer 14 is empty, a flap 30 (which is normally in the full-line position shown) is deflected with a suitable time delay, so that the absence of the article in the lane concerned, is made up by deflection by the flap 30, of an article from the other lane. If the compartments 17 continue to be sensed as empty, the flap 30 is alternately oscillated back and forth so as to share the articles from the remaining active lane with the two downstream lanes. If the sensors 43, 44, indicate articles are missing from both lanes, the slide members 20, 21, are lowered by rams 23, 23, and convey the articles to relief shoots 25, 26. Counters 46, 47, monitor the feed of articles into the containers 11. A sensor 48, on reading that a container 11 is empty, causes the members 20, 21, to be retracted to connect with the relief shoots 25, 26.

IPC: H04L27/04
Filed: 1960-04-01
Abstract: 895,359. Transistor gating circuits; keying carrier frequencies. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 10, 1961 [April 1, 1960], No. 11640/60. Classes 40(5) and 40(6). [Also in Group XL(b)] A circuit for keying voice frequency signals under the control of double current signals comprises a network which is such that between input and output terminals of this network there is a high impedance when the signals have one polarity, and a low impedance when the signals have the other polarity. The voice frequency generator S feeds a transformer TRA, the secondary of which is connected to a similar transformer TRB via the emitter/collector electrodes of a first pair of symmetrical transistors VT1, VT2. A second pair of transistors VT3, VT4 is connected in series with resistors R11, R12 and R13, R14 across the transformers. Double current signals are applied at terminal LT. When the signals have positive polarity transistors VT1, VT2 do not conduct but VT3, VT4 do so that the voice frequency signals do not pass to the transformer TRB and the output terminals. If the signals have negative polarity VT1, VT2 are conductive and VT3, VT4 are not, so that the voice frequency signals can pass to the output. The various resistors are so chosen that the impedance presented at the input and the output terminals is unchanged for the two conditions of the circuit. Should there be no signal present all the transistors are biased to their non- conductive condition by means of the 10 volt negative source indicated. If it is required that the voice-frequency signals be blocked when the signal has negative polarity and are passed when the polarity is positive, then links XA and YB must be replaced by links XB and YA.

Title: Magnetic oscillography
IPC: G11B5/02
Filed: 1956-04-17
Abstract: 823,157. Magnetic recording apparatus. CLEVITE CORPORATION. April 17, 1956 [May 16, 1955], No. 11644/56. Class 40 (2). A method and apparatus for magnetically recording a visible oscillatory trace comprises the use of a field-shifting record head having a wide recording gap spanning the width of a premagnetized record band, and producing on said band a magnetic trace capable of attracting the magnetic particles of a magnetic ink. The head comprises a number of alternate laminations 10, 11 of magnetic and non-magnetic material through which a flux from a permanent magnet 14 passes, and a core member 16 forming a magnetic gap 17 and having a signal coil 20 wound thereon. In the absence of a signal, the neutral flux zone existing in gap 17 occupies a mean position, as in Fig. 3, but in the presence of a signal the neutral zone oscillates about the mean position. When longitudinally prepolarized record member is passed over the magnetic gap a trace in accordance with the signal is recorded, such that on one side of the trace the pre-polarization is reversed, while on the other side the original direction of the prepolarization remains. Between the two areas, along the trace corresponding to the neutral zone of the head, the polarity of magnetization is at right angles to the plane of the record, but the polarity alternates according to the direction of the trace across the record. The peaks of the oscillation tend to have no vertical polarity, but this is overcome by feeding a small amount of supersonic frequency into the signal coil. Thus the particles of a magnetic ink adhere only to the path traced out by the neutral zone in the gap. In a second embodiment, vertical pre-polarization is employed, and this has the advantage that supersonic additional frequency is not required. In a third embodiment, transverse pre-polarization is employed, but the addition of a low-amplitude supersonic signal is in this case required. A fourth embodiment employs alternating vertical pre-polarization and offers essentially the same advantages as direct vertical polarization in that no supersonic signal is required.
