Title: Recording and/or playback apparatus
IPC: G11B15/22
Filed: 1970-01-28
Abstract: 1284998 Feeding magnetic record tapes PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 28 Jan 1970 [31 Jan 1969] 4132/70 Heading G5R When an electric (stop foil), optical or magnetic mark on a tape is reached, the drive is disconnected and after a delay to allow the stop mechanism to respond, the tape is driven in the opposite direction until the mark is again passed. The delay circuitry is reset either immediately or upon reactivation of the tape drive. A forward button 3 closes a contact 6 to energize a forward drive relay 1, and also closes a contact 16 to prepare a switching circuit 12. When the marker signal 9 is produced at a device 8, a relay 10 operates to disconnect the drive relay 1, and actuates a lock 5 which releases button 3. The marker signal 9 also passes via bi-stable 24 through a delaying circuit 25, and thence via bistable 26 through OR-gate 27 to enable the switching circuit 12 to energize the reverse drive relay 2 to drive the tape in the opposite direction. When the marker is reached for the second time, the signal 9 appears again and passes through AND-gate 29, resets the bi-stable 26 and itself provides the drive-activating signal through OR-gate 27 until the marker is passed for the second time when the drive is disconnected. If the stop foil is longer that the "run-out" length, signal 9 is continuously applied to AND gate 29, and the operation has the same effect. The storage circuit 23 may be reset by closing contact 33 on reactivating the drive, after a time delay t<SP>1</SP> at 34. Alternatively, a differentiating circuit (31, Fig. 2, not shown) may detect cessation of the actuating signal 22 and may cause the storage circuit 23 to be reset. In this case the disconnecting relay 10 may be connected to the output of bi-stable 24, thus preventing reactivation of the drive until the storage circuit is reset.

Abstract: 348,573. Loud-speakers ; circuits for electrostatic instruments. RAUSER, A. and STEUER, W., 39, Kottbuser-Ufer, Berlin. Feb. 12, 1930, No. 4694. [Class 40 (iv).] In an electrostatic loud-speaker employing a diaphragm 10 which vibrates between perforated electrodes 4, 5 connected to the secondary 3 of the transformer supplying the speech alternating voltage, in order to avoid the use of an auxiliary source of direct current potential, a diaphragm is employed adapted to receive and hold a static charge. In the arrangement, Figs. 1 and 3, the diaphragm consists of one or more stretched layers of very fine films of resinous products, such as rubber, guttapercha, balata, amber, shellac, colophony, &c., either alone or in combination with an insulating supporting fabric of very fine texture and the diaphragm is charged, e.g. by rubbing, before insertion in the speaker. The films 10, Fig. 3, are either stretched directly on the electrodes or on frames 11, spacing strips 12 being located between the films and electrodes. According to the modification, Fig. 2, the diaphragm consists of two very fine fabric layers 13, 14, such as silk, between which is located a conducting or semi-conducting foil 15 which is connected directly or through a high ohmic resistance to earth or, as shown in dotted lines, to the negative pole of the anode circuit. It is stated that with such an arrangement the diaphragm automatically receives a static charge whenever the speaker is brought into operation, this charge being held during the operation of the speaker. The volume may be increased and the purity improved by connecting a high ohmic resistance 18 and also, if desired, a condenser 19 between the transformer windings 2, 3 as shown. Fig. 5 shows a constructional form of the loud-speaker employed in the arrangement shown in Fig. 2, each fixed electrode consisting cf a fine wire gauze 6 fixed on a coarse grating 7 and each silk layer 13, 14 being stretched on a frame 12, the foil 15 lying loosely between these layers.
