Abstract: 521,882. Wireless receiving systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Nov. 30, 1938, No. 34918. Convention date, Nov. 30, 1937. [Class 40 (v)] Interference in a receiver due to signals above a certain amplitude value is prevented by a detector circuit comprising a pair of diodes or like unidirectionally conducting devices provided with a balanced output impedance network to one arm of which biassing potentials in accordance with the carrier level of the received signals are applied so that the biassed arm will only respond to undesired signals having an amplitude in excess of those corresponding to a predetermined degree of modulation in the received signals. A bias potential equal to twice the signal carrier voltage is preferably used. The secondary 7 of an I.F. transformer 6, 7 is connected to the anodes 8 of a pair of diodes the cathodes 10, 11 of which are connected respectively to arms of a bridge comprising pairs of resistances 15, 16 and 19, 20 having intermediary points 31, 32 connected to the grid 27 and cathode 28 of an amplifying valve 14. Variable capacitators 38, 39 are adjusted to balance the phase relation and wave form in the two arms. The contact point 31 in the resistance 16 is made variable so that for strong signals the network may be balanced and the output to the valve 14 is zero. Bias is applied to the arm 15, 16 by feeding part of the signal through a lead 42 to plate 45 of a pair of rectifying diodes included in a valve 46 which may be used as an amplifier in,another part of the circuit. The rectified potentials are applied from the cathode 44 to over a resistance 40 connected at opposite ends to the arms 15, 16 and 19, 20. In Fig. 2 the bridge arms are placed in the anode circuits of the diodes and the cathodes are connected -together and to the secondary 7. In this case the resistor 16 is made variable and is connected through earth points 50, 51 to the end of the bias resistance 33 of the amplifier 14, while the intermediary point 32 is connected through capacity 29 to the grid 27. Biassing potentials are obtained from a rectifier 52 coupled through coil 53 to transformer 6, 7 and are applied over a resistance 54 to the resistance 15 along leads 56, 57 provided with an intermediate and audio frequency filter comprising a resistance 58 and byepass condensers 59.

Abstract: 1,153,922. Printing and applying labels, feeding webs. HOBART MFG. CO. 4 Aug., 1966 [11 Aug., 1965], No. 35070/66. Headings B8F and B8R. General arrangement.-Labels (25) (Fig. 1, not shown) are printed at (41) before they are detached at (46) from the tape, for attachment to an article, the tape (24) being drawn off by a drive (75). Detaching the label.-The label-carrier tape 24 (Fig. 9) is fed under a sharp corner 56 to detach the label 25, and the trailing end of the label is prevented from being carried away with the band by a guard 59 which is serrated at its lower end. The guard 59 is either pivoted, as illustrated, to facilitate threading the label tape, or may be mounted for complete removal, together with a roller 51, after a biasing spring (232) (Fig. 15, not shown) has been removed. The portion of the label-detaching mechanism may be adjusted according to the size of label. Applying the label.-When the article to be labelled depresses a plate (150) (Fig. 5, not shown), a shaft 142 (Fig. 9) is moved rearwardly to position a lip 145 over the forward end of the label. An arm 190 then presses the label into adhesive engagement with the lip 145, and the shaft 142 is moved forwardly (to the left in Fig. 9), so that simultaneous rotation of the lip 145 anti-clockwise as viewed in Fig. 9, applies the label to the article (A) (Fig. 10, not shown). A foot 144 (Fig. 9) which normally serves to hold the lip 145 above the labelsupporting surface 52 also serves (Fig. 10, not shown) to wipe the end of the label on to the particle. The movements of the shaft 142 and lip 145 are derived from a linkage (153) (Fig. 5, not shown) operating conjointly either with a cam device (130) or a second linkage (284) (Fig. 14, not shown). The switch (291) (Fig. 14, not shown) prevents a further label being printed when the previous label has not been delivered. Feeding the web.-Where the web is unperfbrated it may be fed by a friction one-way pawl 91 (Fig. 3), acting on the surface of the web 24 where it passes over a drum 77 mounted on the same shaft 94 as the arm 84 carrying the feed pawl 91. An eccentric 82 permits adjustment of the pawl. Oscillation of the pawl is effected from a cam (115) (Fig. 1, not shown) through a linkage which includes a solenoid (108) which is de-energized, to stop the feed, when a star wheel (32) (Fig. 7, not shown) mounted loosely on a shaft 38 detects the gap (29) between two adjacent labels. Where the tape is perforated it may be fed by pin drum (235) (Fig. 14, not shown) moved in steps by a ratchet mechanism of adjustable stroke. Printing the labels.-The print wheels 41 may be set automatically by a weighing device to print the weight and price of each article. A further printing device (216) (Fig. 14, not shown) may previously apply an indication which is common to all the articles.
