Title: Method and apparatus for controlling the segregation of faulty articles such as cigarettes or the like
Inventor: ESENWEIN ALBERT
IPC: A24C5/34
Filed: 1964-02-11
Abstract: 1,083,111. Cigarette making machines. K. KÍRBER. March 12, 1965 [Feb. 11, 1964], No. 5640/64. Heading A2C. In an apparatus for testing the wrapping of cigarettes or the like and rejecting those which are faulty, a cigarette is subjected to a checking air current during each cycle of the apparatus and variations of the air current which lie outside predetermined limits indicate a faulty cigarette. Such a variation is converted into an electrical signal pulse which is then shaped to form a further control pulse of the duration of a full cycle and with a delay of one cycle. The control pulse is fed to a rejector device for rejecting the faulty cigarette. Changes in the flow of air through a cigarette may be converted to electrical signals by a diaphragm which is fixed in an air chamber having an inlet connected to the air flow through the cigarette and an outlet of predetermined size so that the diaphragm moves in accordance with the air flow through the cigarette. The diaphragm may form part of a variable capacitor or inductance connected in an oscillatory circuit having an output 124 in which pulses 124a-124e occur when the pressure in the chamber varies from the predtermined limits. Pulses 124b, d and e indicate that a faulty cigarette has been tested in the cycle periods A-C, C-E and F-H. Spurious pulses 124a and 124c may occur at the beginning of each cycle. To cancel these, a synchronizing signal pulse source having an output 122 is provided. The waves 122 and 124 are fed to pulseshapers to provide outputs 126 and 128 respectively which are fed to an "and" gate circuit, the output 130 of which consists of square pulses 130b, d, and e corresponding to the fault signals in output 124. The output 130 is applied to a first pulse shift register stage, the output pulses 132b, d and e of which are initiated by the leading edges of the pulses 130b, d and e and last until the end of the respective cycles in which they occur. The pulses 132b, d and e are then fed to a second pulse shift register stage the output pulses 134 of which are initiated by the trailing edges of the pulses 132b, d and e and last for a complete cycle. The original fault signals 124b, d and e thus give rise to pulses having a delay and duration of a complete cycle which are fed to rejector mechanism for rejecting the cigarette which gave rise to the original fault signal.

Filed: 1948-02-27
Abstract: 642,197. Non-linear valve circuits. DEPARTMENT OF COMMERCE, DIRECTOR OF THE OFFICE OF TECHNICAL SERVICES OF. Feb. 27, 1948, No. 5949. Convention date, July 9, 1945. [Class 40 (vi)] A circuit for producing an output proportional to the logarithm of an input signal comprises means for producing from the signal a plurality of signals whose values are proportional to a geometric progression each of such signals being fed to separate networks, the outputs of which feed a common load. A potentiometer 10, 12, 14 divides the input signal applied through condenser 16 approximately into portions having amplitude ratios of 1, <SP>1</SP>/ 10 , 1/ 100  and these are applied respectively to the control grids of three similarly biassed valves 18, 20, 22 having their outputs connected in parallel. As the input voltage rises the output from valve 18 rises until the valve saturates when the more slowly rising output from the second valve becomes significant. This valve in turn saturates leaving valve 22 to supply the output. The combined output is of logarithmic form having a base equal to the ratio of the portions of the signal (in this case 10). In an alternative cicuit (Fig. 2, not shown), part of the output from each of three successive stages of the I.F. amplifier of a superheterodyne receiver is applied respectively to three similar detectors which successively saturate and the outputs are separately amplified and combined.

Abstract: 1,018,921. Signalling by light. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 1, 1963 [Feb. 19, 1962 (2)], No. 6353/62 and 6354/62. Heading G1A. [Also in Divisions F4, G2 and H1] A signalling system embodies a sodium vapour discharge lamp as a light source and to increase the signalling distance a filter is utilized at the receiving end, the filter transmitting the monochromatic radiation of the lamp but blocking the other wavelengths of the atmosphere. The signalling is performed by varying the power input to the lamp to produce flashes and in order to maintain the vapour pressure when the lamp input is interrupted or at a low value the lamp is provided with heating means, these means being controlled such that the vapour pressure remains substantially constant irrespective of the value of the signalling input. As shown, Fig. 1, a sodium vapour discharge lamp 13 having electrodes 11, 12 is supplied from a D.A. source 14 modulated for signalling by a modulating transformer 18, the circuit including a stabilizing resistor 15, a current limiting resistor 16 and a start switch 17. The receiver includes a filter 25, photo-electric cell 21 and a resistor 23 applying voltage variations to an A.C. amplifier 26 energizing an earphone or loudspeaker 27. In another system, Fig. 2 which is a modification of Fig. 1, three lamps 28 are connected in parallel across an A.C. source 29 through normally-open contacts 30 of a contactor 31, the contactor operating coil being connected across terminals 29 through a signalling key 32. Each lamp has a stabilizing inductance 33 and connected in parallel with the lamp and part of the inductance is a capacitor 34 to produce surge voltages when the key 32 is operated. In order to maintain the vapour pressure in the lamps when the contacts 30 are open each lamp has a heating resistor 35 connected across the terminals 29 through back contacts 37 of the contactor 31. When the key 32 is closed contacts 30 close and contacts 37 open whereby the resistors 35 are connected to terminals 29 through a resistor 36. Further to facilitate discharge through the lamps the lamp electrodes are kept heated by secondary windings 40 of transformers 38 having primary windings 39 connected directly to supply terminals 29. A lantern, Fig. 4, for the lamp 50 has a parabolic trough shaped reflector 52 in a housing 51 having a window 53, the housing being carried by brackets 55 secured to a vertical support 57 through vibration absorbing pads 59. The lamp is particularly intended for marine signalling where the light source is to be visible through a wide azimuthal angle, e.g. 360 degrees and to this end a number of lamps 61 may be mounted in a common plane on a ship mast 60, Fig. 5. Instead of the single lamps 61 as shown in Fig. 5 each lamp may be replaced by a number of lamps mounted one above the other in ladder-like formation.

[Class 40 (iii)] To derive framing and line synchronizing signals from mixed synchronizing signals, a condenser 5, in parallel with a resistance 4, is charged under the control of a valve 1, and the time constant of the resistance and condenser is greater than the intervals between the synchronizing signals but is made effectively short by a diode 6 or other unilateral conductor which maintains a predetermined voltage across the condenser in the intervals between the signals. The mixed signals are applied to the input circuit 2, 3 of the valve. The resistance and condenser are in the anode circuit of the valve and the diode is so connected between a potentiometer 9, 10, 11 and the anode that the diode only conducts when the charge on the condenser reaches the predetermined value. The cathode of a diode 7 is connected to the anode of the valve 1 and the anode if the diode is connected to a point 14 on the potentiometer such that the diode conducts only on the occurrence of a framing signal. The diode is connected to the potentiometer through a coil 13 which is coupled to a blocking oscillator producing a saw-tooth wave. When the valve 1 is of the screened-grid type, the line-frequency signals are taken from the screening grid.
