Filed: 1975-05-13
Abstract: 1515123 Tape recorder circuits LICENTIA PATENT VERWALTUNGS GmbH 13 May 1975 [17 July 1974] 20132/75 Heading G5R The amplitude of the high frequency bias current through a magnetic recording head 1 is reduced by selectively connecting an inpedance 8, 9 across the head 1. The circuit may be operative to effect changeover for different tape speeds, or different tape types, such as Fe 2 O 3 , CrO 2 , cobalt or multilayer tapes. In an Fe 2 O 3 / CrO 2  changeover circuit a high-frequency generator 3 supplies base head 4 with a constant base level irrespective of tape type. The head 1 is fed with an audio signal to be recorded via impedance 2 and with high frequency bias from generator 3 via capacitor 5 and resistor 6. In the Fe 2 O 3  position of switch 7 the bias to head 1 is reduced by shunting the head with a series circuit of capacitor 8 and resistor 9, this circuit having little shunting effect on the audio signal. In the CrO 2  position of switch 7, circuit 8, 9 is disconnected and a branch 10, 11 of an equalizing circuit of a playback amplifier 12 for head 1 is earthed. In a cassette tape recorder, switch 7 may be operated by a cassette on insertion thereof, the cassette having a mechanical coding according to the type of tape therein.

Title: Delivery Device for Folded Signatures
IPC: B65H29/60
Filed: 1968-04-29
Abstract: 1,198,926. Delivering folded sheets. PUBLICATION CORP. 29 April, 1968 [1 May, 1967], No. 20206/68. Heading B8R. Folded sets of associated signatures travelling along a pre-determined path are alternately delivered to two separate receiving points by apparatus including two spaced-apart fan units, each fan unit having means defining a plurality of signature-receiving spaces. The invention is particularly applicable to a webprinting press, wherein the web is longitudinally cut, after printing, into a number of ribbons which are placed over each other, cut transversely and folded to form the sets of associated signatures. The sets of signatures B are fed in turn between feed rollers 12, 13, Fig. 1, and against a guide 8; they are then fed alternately to either a first fan unit 16 or a smaller-diameter second fan unit 30. Each fan unit or S-fly is formed of a number of discs, such as 18, spaced at intervals along a rotatable shaft 19, and curved fingers 20, which together with the underlying segments of the discs, define signature-receiving spaces such as S 1 -S 6 . The paths of motion of sets of signatures on the two fan units are non-overlapping and stop members 24, 40 cause the sets of signatures to drop on to conveyers 26, 42 so that they are delivered in overlapped fashion to, e.g. bookbinding machinery. The second fan unit 30 may be equipped with cam-operated grippers 38. Switching delivery.-Alternate signature-receiving spaces on the fan unit 16 are blocked by assemblies 44 whose outer surfaces guide sets of signatures towards the spaces of the second fan unit 30. (Also Figs. 2A and 2B, not shown.) Alternatively there may only be three receiving spaces on fan unit 16 separated by portions of the peripheries of the discs 18, with the upper surfaces of the curved fingers 20 acting as guides for diverting delivery to the second fan unit (Fig. 3, not shown). The finger elements of the second fan can be resiliently mounted so as to deflect and by-pass any obstructions, e.g. paper wads resulting from incorrect feed, or they can be pivotally mounted for similar reasons.
