Filed: 1958-07-07
Abstract: 892,422. Statistical apparatus; recording apparatus. NIELSEN CO., A.C. July 7, 1958 [July 8, 1957], No. 21725/58. Classes 106 (1) and 106 (4). Data carried on a number of tapes 22, Fig. 2, each relating to a single domestic receiving set and indicating by longitudinal lines that, during a certain time, the set was switched to one channel or another, or by no line to indicate that it was switched off, is collated with respect to time on a pair of tapes, 16, 17, Fig. 3, one for each channel by an operator using the apparatus shown which has means for simultaneously feeding one of the tapes 22 past a viewing position and the tapes 16, 17 past recording styli 20, 21, buttons 24, 25 being provided which the operator presses when the lines on tape 22 pass a mark 26 to record a similar line on the appropriate tape 16 or 17. The tapes are driven in one direction by motor 18 and in the other by motor 19 and the drive to tape 22 is coupled through a clutch 35 which is released when it is necessary to position the tapes 16 and 17 to the same period of time as that to which of the tape 22 refers. The tape 16 is shown in Fig. 5, the times being indicated in the upper margin and the stylus marks, one for each sample receiver, being arranged across the tape each in a transverse position corresponding to its receiver, the length of this line showing the time for which that receiver was in use on the channel corresponding to the tape 16. After each tape 22 has been examined the styli are moved transversely of the tapes 16 and 17 by a rack 33 and pinion 32 operable by a wheel 31. The motors 18, 19 run at two speeds; a fast speed for running those parts of the tape 22 through the viewing position which have no data-indicating line and a slower speed allowing the operator time to press the buttons 24, 25 when lines are observed. The motor speed is controlled by buttons 27, 30. An interlock prevents both stylus buttons being pressed at the same time. The number of receivers in operation on a particular channel at any time may be counted by eye or by a photo-electric device moved across the tape at the corresponding position. In another form of tape, Fig. 7, dots are made in a track of the tape for each receiver switched to a corresponding station. The tape is divided into lengths representing a minute and each minute portion is divided into the number of receivers in the sample. A magnetic mark or a hole is punched in the appropriate position to indicate that a receiver is switched to one channel or the other at that time. Alternatively, the sample tapes 22 may be used to punch record cards. Specifications 823,361 and 847,596 are referred to.

Abstract: 281,776. Brown, W. J., and Metropolitan-Vickers Electrical Co., Ltd. Sept. 10, 1926. Thermionic valve circuits.-In a wireless receiver in which the source 10 of high tension comprises the D.C. mains or a source of rectified A.C., hum is eliminated by means of two different filter circuits applied respectively to the power valve 8 and the preceding amplifier and detector valves 2, 4, 6, which are all provided with resistance-couplings as indicated at 3, 5, 7. The filter for the power valve comprises a, coil 13 of great current capacity but less inductance than the coil 12 associated with the earlier valves; the coil 13 consists of thick, the coil 12 of thin wire, and each is wound to the same bulk on one of the halves of the laminated core shown in Fig. 3. This arrangement makes use of the fact that the power valve is less sensitive than the earlier valves to humming voltage components, owing to its lower amplification factor. The total bulk of the coils is less than the bulk of a single coil suitable for all the valves. Each coil is shunted by a condenser 14, 16, and a common condenser 18 may be added; the end 20 of the coil 12 may be connected to the source 10 either directly or through a potentiometer 19 as shown. The coil 12 and condenser 14 may be replaced by a group of series coils and shunt condensers. The Specification mentions suitable dimensions for the parts of the apparatus.
