Patent GB-1000386-A (GB)
Title: Improvements in or relating to magnetic tape handling apparatus
Inventor: LEMEN HUGH SPENCE
IPC: G11B27/36
Filed: 1964-03-12
Abstract: 1,000,386. Editing apparatus. STANDARD TELEPHONES & CABLES Ltd. March 12, 1964, No. 10469/64. Heading G5R. Magnetic tape record editing apparatus includes means for repetitively scanning a selected length of tape including a portion to be edited and means for deriving signals indicative of the start and finish of this portion. The length of tape 1 containing the portion to be edited is partly wrapped around a rotating disc 2 which has a record/playback head 5 and a diametrically opposed erase head 6. On the disc are two magnetic markers 7, 8 which co-operate with a stationary coil 9 to generate a pulse for every 180 degrees rotation of the disc. With the tape held stationary, the portion around the disc is repetitively scanned by the head 5 on the disc 2 and the recording listened to by headphones 10 connected via an electronic change-over switch 11, having two paths, one being on when the other is off. Each reference pulse activates a first delay circuit in unit 13 to produce a pulse which opens the path between head 5 and phones 10 and closes that between head 6 and generator 12. A second delay circuit either actuated by the reference pulse or by the output from the first delay circuit closes the first path again and opens the second. These two delay circuits are adjusted until the unwanted portion is no longer heard, and the erase generator 12 then energized so that on the next actuation of the switch 11 the erase head removes the unwanted portion. The erased portion may be replaced with a correct recording, Figs. 2, 3 (not shown), by providing a second disc similar to first coupled to the switch 11 and carrying the required tape. Thus by using the delay settings determined by the erasure, the second tape is adjusted on the disc until the required passage is substituted during the change-over of switch 11. Once this has been achieved, the correct section of the second tape is fed to head 5.

Patent GB-105589-A (GB)
IPC: G11B7/00
Abstract: 105,589. Bullis, H. C. April 13, 1916. Kinematograph apparatus. - Talking-picture apparatus is arranged to record sounds and picture simultaneously on independent film strips, and means are provided for marking each film with a series of identification marks so as to facilitate assembly for simultaneous reproduction. The recording-apparatus shown in Figs. 1 and 2 comprises pairs of reels 2, 4 for winding and unwinding the sound and picture films 11, 10 which are arranged side by side. A third opaque strip 13, wound on drums 3, 5 and overlapping the nearer edges of the films 10, 11, is provided on its edge with perforated characters, such as numerals. The three films are driven by toothed rollers 7, 8 one rotating continuously and the other intermittently, a loop 9 being interposed in the usual way. Each roller 7, 8 has four rings of teeth, the two inner rings engaging both the marking-strip 13 and the perforated edge of one of the records. Sounds are recorded on the film 11 by an incandescent electric lamp 23 having a single horizontal filament, the lamp circuit being connected inductively to a microphone circuit 28. The steady currents in the microphone and lamp circuits may flow in the same or opposite direction in the transformer coils. The light is focussed through the slot 20 to produce a transverse line on the sound film by a cylindrical lens 22 of double-convex section and with curved ends. Immediately over the soundrecording aperture is arranged a lamp 35 adapted to print the identification marks through the edge of the marking strip 13 on to the edge of the sound-recording film 11. A similar lamp 17 is arranged above the picture aperture 14 to print corresponding marks on the edge of the picture film 10. The identification marks on one edge of the marking strip 13 are set forward relatively to those on the other edge, to allow for the film in the loop 9. When numerals are used, this gap is preferably arranged to correspond to ten picture spaces so that the numerals opposite each other differ by ten. After separate development, the negative sound and picture films are used to] obtain positives by contact printing or otherwise, and the positives are assembled by means of the identification marks, and, if desired, cemented together. The reproducing-apparatus, shown in Fig. 8, comprises drums 37, 38 for the films, and two toothed driving-rollers 39, 40 one rotating continuously, the other intermittently. Each roller has three rings of teeth, the central ring engaging perforations in the overlapping edges of the sound and picture films, the marking-strip not being required in reproducing. The sound-reproducing device comprises a lamp 43 focussed by lenses through a slit 42 on to the sound-film, the varying transparency of which allows light of variable intensity to fall on a selenium cell 43<1> connected to a telephone receiver 45.

Title: Improvements in or relating to circuits for the transmission of ultra-high-frequency oscillations
IPC: H03F1/08
Filed: 1947-04-24
Abstract: 633,728. Valve amplifying circuits. PHILIPS LAMPS, Ltd. April 24, 1947, No. 10978. Convention date, Nov. 3, 1944. [Class 40 (v)] In a circuit for the amplification of ultra-highfrequency oscillations by means of two pushpull connected discharge systems, the centres of the input and output impedances are connected through an inductance of such magnitude that reaction upon the input circuit uf co-phasal voltages on the output electrodes is substantially neutralized. As shown, the discharge tube 1 which contains two amplifying systems has the cathodes internally connected to each other, the suppressor grids being connected to the cathodes in the usual manner. The screen grids are also connected together inside the tube. The control grids are connected to an oscillatory input circuit 7 and the anodes to an oscillatory output circuit 10, the cathodes being connected to earth via a resistance 13 and condenser 14 in parallel and also via a condenser 15 to the centre 16 of the circuit 7. Automatic volume control may be applied through a resistance 17. The screen grids are connected via condensers 18 and 19 to the centre 20 of circuit 10. The reaction caused by co-phasal voltages set up at the anodes upon the input circuit is neutralized by a suitably chosen inductance 23 between the centres 16 and 20 of circuits 7 and 10. Under certain conditions the inductance present between point 24 and earth may be excessive and in this case neutralization may be effected by inserting an inductance between the cathodes and point 24 or between the screen grids and point 25. The Specification gives the equivalent circuit from which an expression for the value of inductance 23 is derived.
