Title: Testing device
IPC: H04B3/466
Filed: 1972-10-13
Abstract: 1413805 Measuring distortion in four terminal networks and frequency modulators WANDEL U GOLTERMANN 13 Oct 1972 [19 Oct 1971] 47407/72 Heading G1U The peak amplitude UA of a first voltage U A = A  sin wt is controlled automatically in accordance with the frequency of a second voltage U M =U M  sin #t in such a way that when the two voltages are applied simultaneously to a frequency modulator its (unshifted) carrier frequency F o  and the first pair of sidebands, F o f M , resulting from the second voltage UM are periodically swept by the first voltage UA, at a relatively low frequency f A , cyclically over the range F o -#F s  to F o +#F s , where #F s  is a pre-set bandwidth. Fig. 2, first line, shows the carrier F o  and the first pair of sidebands from the second voltage UM in three different positions, resulting from sweeping by the first voltage UA. As the frequency fM is raised, in order that two sidebands do not go outside the range F o -#F s  to F s +#F s , the peak amplitude of the first voltage must be reduced. This is achieved automatically, and the successive lines of Fig. 2 show successively larger values of fM, and consequently smaller sweeps, of width #F, by the voltage UA. In the circuit described, Fig. 3, two controls have to be pre-set: firstly a control 20a has to be set to represent the desired range #F s , and secondly a control 15a has to be set to represent the voltage U s , which if applied by itself to the frequency modulator, would produce a frequency shift in the carrier of amount #F s . A reference signal U o = o  sin wt (i.e. of the same frequency as UA) is then applied to the circuit, together with the second voltage UM, which may come either from an unspecified source 30 or from a local oscillator 7 and as a result voltages U A  and U M , together with their sum UT, are produced by the circuit, the peak amplitude UA of the voltage UA bearing the desired relationship to the frequency fM. This is achieved as follows. The peak valve U o  of the voltage U o  is extracted, 24, and multiplied by a factor #F s /#F s   max , 22, 23, (#F s   max  being a constant of the circuit) and applied to a unity-gain amplifier 25 where an amount  o f M /#F s   max  from a frequency discriminator 27 is subtracted from it. The resulting difference voltage, after multiplication by a factor U s /U o , 18, 19 is applied to a high-gain amplifier 17, which so controls the tapping of a potentiometer 14, that the peak value UA of the voltage UA tapped from it, multiplied by #F s /#F s   max , 20, 21 has the same value as the scaled difference voltage. This is expressed by the following equationwhich is the desired relationship to ensure that the sweep produced by UA always just covers the range F o -#F s  to F o +#F s . The voltages produced are intended either for use in testing a frequency modulator, or for application to a frequency modulator in order to produce signals for testing a four pole network over a desired bandwidth.

To reduce the risk of separation of the cord ends of tread bracing layers 7, 8 of a pneumatic tyre with a radial cord carcass 6, separate reinforcements 9 are provided in the tyre shoulders each extending from within the width of the layers 7, 8 to a line in the near sidewall a distance d from the edge of the layers 7, 8, d being between # and # of the width l of the reinforcements. The stiffness of the sidewalls where braced by the reinforcements 9 is less than that of the tread, e.g. by having the cords of layers 7, 8 of steel and those of reinforcements 9 of textile material, or by different numbers of layers. The cords of the reinforcements 9 make an angle between 40 and 80 degrees with the carcass cords and are disposed close to the carcass cords in the sidewalls. They may lie radially inside, outside, or between the layers 7, 8.

Abstract: 1,026,959. Pulse transmission system. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 30, 1964 [Dec. 23, 1963], No. 48521/64. Headings H3T and H4R. A pulse transmission system comprises a switch, e.g. transistor 10, and a pair of complementary emitter followers 17 and 18, feeding a transmission line 24 terminated by its characteristic impedance 32. An output transistor circuit 33 and 34, is connected across the line where an output is required. The arrangement is such that, in the absence of a pulse input at 11, the transistor switch 10 operates in saturation causing transistor 17 to be cut-off and 18 to conduct to apply a slight negative potential to line 23 to cut-off the transistors, e.g. 40, in the output circuits. On the arrival of a pulse on the input 11 transistor 10 is cut-off to cut-off 18 and cause 17 to conduct in saturation so that a potential approaching - 12 volts is applied to line 23, which causes the transistor output circuits to conduct and cause conduction of the output transistors, e.g. 47. The current limiting resistors 43 are chosen to ensure the desired minimum emitter collector current in transistor 14, the valve of the resistor decreasing as the distance from the driver circuit increases.

Punched tapes bearing minute-by-minute records of the use of television sets are converted into a set of punched tapes, one for each day of the week, in a suitable form for computer input. After entering control marks, the appropriate starting time and the sample number, corresponding to a first record tape to be read, on the first day computer tape, the first record tape is sensed. A counter is concurrently advanced as the record tape is sensed, and each time a change in tuning channel or in the on/off condition of the sample TV set is detected on the record tape a corresponding recording, e.g. channel, on/off is made on the computer tape together with the time of the change derived from the counter. At the end of the first day's data on the record tape, data is entered on the second computer tape in a like manner, and so on for successive computer tapes until the end of the sample record tape is reached-corresponding to one week's use. The process is repeated for the other sample record tapes.

Furnace black is made by incomplete combustion of liquid hydrocarbons, optionally in the presence of a fuel gas, where the combustion flame is supported by air containing more than its natural 21% by volume, of oxygen. The percentage range specified is from 22 to 100%. By arrangement of the air/oxygen mixture with the amount of starting material, blacks of different specific surfaces can be made. The criterion specified, in order to work at a predetermined temperature to produce such blacks, is that the oxygen must be reduced in proportion to the amount of starting material for the black, although simultaneously being present to greater than 21% by volume in the air used. Two methods are specified, one involving reduction of the amount of oxygen itself, and the other involving increasing the amount of starting material.
