Title: Improvements in or relating to pilot signal control systems
IPC: H04B3/10
Filed: 1968-09-18
Abstract: 1,247,173. Automatic volume control. SIEMENS A.G. 18 Sept., 1968 [19 Sept., 1967], No. 44231/68. Heading H4R. In a pilot controlled a.g.c. system in a telecommunications system the pilot signal is detected by a filter 13 at the output of an amplifier 2 and is rectified in rectifiers 8 and 9 to cause a change in potential on the base of transistor 20, variations in pilot level thereby causing charge or discharge of capacitor C and hence varying the source drain impedance of f.e.t. 4 which is connected in the negative feedback path of amplifier 2 so as to regulate the gain. Diode 5 and resistor 6 are connected across the resistor R to reduce the time constant of the storage capacitor circuit when the received pilot signal exceeds a reference level. The pilot rectifier circuit is arranged so that interference pulse, e.g. from dialling pulses, cause switching of the transistor 20 between its conducting and non- conducting states and the time constant of charge and discharge circuits of the capacitor C are so large that the stored voltage changes only slowly toward a value appropriate to the mark space ratio of the pulses. Reduction of pilot signal below a predetermined level causes transistor 10 to cease conduction releasing relay A which over contacts A1 operates an alarm and over contacts A2 modifies the circuit of capacitor C to tend to hold the charge therein at a mean value. In addition a f.e.t. (32, Fig. 3, not shown) can be connected in series with the charging circuit of capacitor C, which transistor is normally conducting but if an A.C. signal appears at the base of transistor 20, due, e.g. to dialling pulses, the transistor is cut off which makes f.e.t. (32) non-conducting, isolating capacitor C from the charge discharge circuit, so that the charge on the capacitor is held at the value which it had immediately before the interference occurred. To reduce leakage the capacitor is returned to a mean potential point on a potentiometer (28, 29) and the capacitor and associated components enclosed in a screening box maintained at the same potential.

Abstract: 1383061 Character recognition systems SIEMENS AG 27 Sept 1972 [27 Sept 1971] 44643/72 Heading G4R A character recognition system which is insensitive to off-centring comprises a preprocessor in which image points in the scanned field are processed in parallel to provide a translationinvariant classification matrix. In one embodiment, illustrated by Fig. 4 which shows a simplified form of such a system using only 3 Î 3 image points, the outputs of the rows of 3 scanning photodetectors PD are connected as indicated to respective groups of 3 units SG. Each unit comprises an operational amplifier arranged to generate a required one of a number of Walsh functions, i.e. each generates an output which is formed by summing some of the 3 inputs and subtracting the others. The outputs represent a first transformation of the image matrix. The output from each unit in each row is connected to a respective second group of 3 units SG as shown, to provide a second 3 Î 3 transformed image matrix. The signals of this matrix pass to a resistor unit KP which feeds an arrangement of diodes DS providing a 2 x 2 matrix which is translationinvariant and is used in known manner to identify the character according to its significance probability. In another embodiment (Fig. 5, not shown), in which the outputs of each row of photodetectors PD are passed in turn to a store, the elements in the store store values representing Walsh functions, the elements being controlled by shift registers generating the appropriate add and subtract signals according to the row selected. The resulting signals undergo a second transformation to provide the 3 x 3 transformed image matrix from which the 2 x 2 matrix is derived as in the first embodiment.

Abstract: 1533553 Analogue to digital conversion NIPPON HOSO KYOKAI 29 Oct 1975 [6 Nov 1974] 44684/75 Heading H3H In an a-to-d converter the reference voltage for a comparator 8 to which an input is supplied is derived from static levels of the input itself, e.g. the synch. signals in a television system. In one embodiment where the static level is the lowest reached by the input a record comparator 9 takes the input and compares it with the voltage 13, on a reference line, if below then comparator ouput makes diode 14 conductive and the voltage on capacitor 16 drops, bringing the voltage at 13 down by feedback through buffer 19. When the comparator 9 output changes the diode is non conductive and capacitor 16 slowly changes through resistance 17. The converter may be a cascade type, or parallel comparator type, or a mixture of both, and the clamped point may be at one end of a reference chain, or in the middle, clamping being performed as a result of a pulse from a central unit.

Abstract: 1372046 Knitting-machines VYZKUMNY A VYVOJOVY USTAV ZAVODU VSEOBECNEHO STROJIRENSTVI 1 Oct 1971 45895/71 Heading D1C [Also in Division H1] In electromagnetic control for e.g. the needles of a knitting machine to produce predetermined patterns, a permanent magnet 2 having polepieces 1 separated by an air gap is assembled with an electromagnet 3 having a yoke surrounded by an exciting coil 4. A ferromagnetic controlled member 6 operative on the machine is located to close the magnet circuits of the permanent magnet and the electromagnet; the latter being positioned so that its flux in the member is normal to that of the permanent magnet. The permanent and electromagnets may be placed on the same side of controlled member (Figs. 1b, 2) or an opposed sides thereof (Figs. 4, 5, not shown). Distance pieces of hard material e.g. sapphire are used to delimit air gaps between the individual magnetic circuits and the controlled member to prevent polepiece wear and to provide a guide which may e.g. engage a slot of such member. In operation the controlled member 6 located in a groove of a needle cylinder of a knitting machine is aligned by relative movement along direction S with the pole pieces 1 of permanent magnet 2 and is attracted thereto by force P m ,which overcomes a restoring force Pdir so that member 6 remains attracted to the polepieces. Application of a current pulse to the coil of electromagnet 3 produces a magnetic field threading member 6 which interacts with the field of permanent magnet 2 to reverse, weaken, or cancel its field. The sum of force Pdir and force Pe due to electromagnet 3 exceeds the force P m  so that member 6 is released from the polepieces of magnet 2 and selects a needle setting e.g. for knitting action. In the absence of a pulse member 6 remains attracted to the polepieces selecting a needle setting e.g. for missing action. In a modification (Figs. 4, 5 not shown) the controlled member is located between the electromagnetic and permanent magnetic circuits which are disposed of opposite sides of it, so that the member is movable relatively to both magnetic circuits or alternatively the member and the PM circuit are moved relative to the EM circuit. Plural such devices may be disposed serially along the periphery of a knitting machine to obtain (Fig. 2, Fig. 5 not shown), successively a first selection of a needle position (knitting action) a second selection of needle position (tucking action) and in absence of these a third selection of position (missing action).
