Title: Video recording and reproducing
IPC: G11B/
Filed: 1973-12-20
Abstract: 1448380 Video recording and playback SONY CORP 20 Dec 1973 [23 Dec 1972] 59138/73 Heading G5R Video signals phase modulated on to a carrier signal are recorded on a medium I, Fig. I, in successive parallel record tracks, T n-1 , T n , T n+1  which abut along their longitudinal edges, line and field sync. signals H, V in adjacent tracks being aligned with each other in a direction at right angles to the track length, and the recorded signals are reproduced by scanning over a width d greater than the track width so as to simultaneously scan and reproduce signals from the full width of one track T n  and a portion of the width of the two immediately adjacent tracks T n-1 , T n+1 . Corresponding components of the modulated carrier are phase aligned with one another in successive tracks so as to have the same relative phase as one another at corresponding portions of each track. Such recording and reproducing allows the usual head tracking servo to be omitted in the playback apparatus. The modulated carrier has a modulation index of less than 2À405 radians, preferably less than 1À0 radians. The tracks may be recorded as successive spiral turns on a magnetic disc 1 by a head having a transducing gap of width P and played back by a head having a gap width d. Alternatively the same head, having a gap width d, may be used for both recording and playback, the successive areas scanned by the head being in overlapping relation so that when recording track T n  for example, the signal previously recorded in the overlapped part of track T n-1  is erased and replaced by the T n  track signal, the degree of overlap being chosen so that the non-erased sections have the desired width P. The video signals may alternatively be recorded as oblique tracks on magnetic tape or as tracks extending substantially parallel to the length of a rectangular magnetic sheet 11, Fig. 8, which is inserted in the gap 15 between a guide 13 and a rotating drum 14 carrying heads 12a, 12b, one end of sheet 11 abutting a stop 16 and the sheet being moved parallel to the axis of drum 14 during recording and playback. The video signals may alternatively be recorded electro-optically to give variations in light reflectivity or transmission of the record medium or as variations in capacitance of a medium comprising a dielectric coating, e.g. polystyrene, on a copper or aluminium layer on a vinyl base, or as depth variations along the tracks on a plastics foil medium, a diamond stylus of a piezo-electric or ceramic transducer tracking the grooves for playback.

Title: Electrical circuit for providing temperature compensated current
IPC: G05F1/56
Filed: 1971-12-29
Abstract: 1375998 Automatic current and voltage regulation R C A CORPORATION 29 Dec 1971 [7 Jan 1971] 60354/71 Heading G3X A temperature-compensated current source comprises a transistor with an emitter resistance. The output from a regulated voltage divider is  supplied across the base-emitter junction of the transistor and the resistance. The temperature coefficients of the resistance and the voltage applied to it by the voltage divider are chosen to be equal. In the circuit shown, an unregulated supply voltage is applied across terminals 14, 16 so that an avalanche or Zener diode 12 produces a regulated voltage for application to a voltage divider 22 comprising resistors 28, 30 and a transistor 24 with an emitter resistance 26. In operation, the zero temperature coefficient diode 12 and the temperature independent divider 22 are so chosen that the voltage applied across emitter resistance 18 has a temperature dependence equal to the temperature dependence of the value of resistance 18. A regulated current is now produced at the collector of transistor 32, which is an NPN transistor fabricated in integrated circuit form. The value of the current is determined by the value of resistance 18. Further transistors 36 may be connected with their baseemitter junctions across diode 20 to provide multiples of the current from transistor 32.

Title: Localising faults in a.c. lines
IPC: H02H3/40
Filed: 1968-12-24
Abstract: 1, 248, 476. Locating faults in electric power lines. COMPAGNIE DES COMPTEURS. Dec. 24, 1968 [Feb. 27, 1968], No. 61424/ 68. Heading G1U. The distance to a fault in an A. C. power line is determined from the ratio of the instantaneous values Uo, Vo of signals U V which are functions of, respectively, the voltage across and current in the faulty loop, measured at an instant when the fault current is presumed to be zero. In a preferred embodiment the signal U is proportional to the voltage across the faulty loop and the signal V is proportional to the voltage drop that would exist in the corresponding loop of a fault free replica line carrying the same currents, at the instant of measurement, as the actual line under observation. The signal V is thus given by the equation: # = r i + l di## where r, l are constants of the line and i is the current in the faulty loop. The instant at which the fault current is zero is presumed to coincide with the difference in the line currents of the relevant two phases becoming zero if the fault is between two phases, or with the zero-sequence currents becoming zero if the fault is between one phase and earth. The system shown continuously monitors three-phase line A, B, C so as to provide an indication of the location of any fault that occurs between two phases or between a phase and earth. Unit I supplies the interphase and phase-toneutral voltages U for all the phases. Unit 2 comprises transformers Fig. 3, (not shown) connected to the line current transformers and arranged to derive the corresponding voltages V. Unit 3 supplies voltages W proportional to the differences between each pair of line currents and to the zero sequence current. Unit 4 is a phase selector which on detecting a fault in any loop selects the corresponding U, V and W voltages and applies them to locking samplers 5, 6 and zero detector 7 respectively. When a zero in the signal W applied to detector 7 occurs a locking signal is applied to samplers 5, 6 so that the instantaneous values Uo Vo of their inputs at that instant are held indefinitely. The ratio Uo/Vo may be evaluated automatically and indicated in digital or analogue form.

Title: A heat reflecting pane and a method of manufacturing the same
IPC: C03C17/27
Filed: 1978-12-13
Abstract: A heat reflecting pane is formed by vacuum deposition of a first Ti film on a glass substrate relatively slowly at a vacuum of the order of 10<-4> Torr, and subsequent deposition of a second Ti film on the first Ti film relatively quickly at a vacuum of the order of 10<-5> Torr. The pane is then heated in air in a conventional thermal toughen- ing furnace to oxidize the first Ti film to an intermediate TiO2 film in the anatase form and said second Ti film to an outer TiO2 film in the rutile form, the pane then being chilled to toughen the glass. The invention overcomes the problem of the dulling of the TiO2 film which occurs in reflective TiO2 coated glass panels prepared conventionally.
