Abstract: 1,052,424. Weighing apparatus. SANOS MEASUREMENT CORPORATION. Sept. 26, 1963 [Sept. 27, 1962], No.37860/63. Headings G1N and G1W. Relates to an apparatus for weighing rolling loads comprising a weigh section rail 31 (Fig. 1) supported at each end so as to allow deflection of the rail in the length between the supports and having resistance strain gauges connected to the under planar surface of the rail to sense the deflection due to a load on the weigh section. Rigidly attached to a respective end of the weigh rail 31 are pins 38, 39 which are journalled in roller bearings on stationary brackets 50, 51. Resistance strain gauges 77, 78 are attached under the rail 31 at points equidistant longitudinally from the centre of its span (see Fig. 14), and may be connected in a bridge network together with two fixed resistances Fig. 8 (not shown), the output of the bridge network when unbalanced being fed to a computer or recording device. A switch 85 is provided which is operated by a wheel supporting a load to be measured so as to connect the output of the network to the recording device only when the wheel is at the mid way point of the weigh rail span. In order to compensate for unbalance of the bridge due to the effect of temperature change on the strain gauges 77, 78 additional strain gauges 79, 80 (Fig. 1, 14) are provided. The latter gauges are connected in the bridge network in place of the fixed resistances and the simultaneous increase in resistances of gauges 79, 80 act so as to tend to decrease the bridge output and thus to maintain the output independent of temperature. In addition the gauges 79, 80 are fixed transversely of the weigh rail and in accordance with Poissons Ratio are in compression when the gauges 77, 78 are in tension due to a load on the rail, and thereby decrease in resistance as the load increases. The resulting unbalance voltage of the bridge network, is therefore taken as a measure of the load and is illustrated graphically in Fig. 18 (not shown). There may be two parallel weigh rails to support two wheels joined by an axle, each rail being similarly equipped with strain gauges, and corresponding gauges on the pair of rails connected in series on a respective limb of the bridge network Figs. 20, 21 (not shown).

Abstract: 1,054,242. Correlation techniques. SEISMOGRAPH SERVICE (ENGLAND) Ltd. Nov.8, 1962, No.35266/66. Divided out of 1, 054, 241. Heading G1U. An apparatus for the filtering or transmission of a waveform comprises a first correlator for effecting cross correlation of the waveform against a reference waveform and a second correlator for cross correlating the output of the first correlator with a time inverted version of the same reference waveform. The correlators described in Specification 1, 054, 241 may be used for carrying out the required correlations. The present double correlating arrangement may be employed to improve the filtering technique described therein. To ensure that the output derived by the filtering correlator explained therein from a non periodic filter is directly significant it is fed to a recording head in a second correlator with a correlating head of the same form as that used in the first correlator, but reversed in time. This second head may also have shorting links and resistors so that two frequency selective actions are cascaded, the entire filtering action being achieved with zero phase distortion. Two such correlating heads may be incorporated in a single disc arrangement. Fig. 7 (not shown). The double correlating arrangement may also be used for the transmission and resynthesis of speech by coded phonemes, the derivation of which is discussed in Specification 1, 054, 241. The coded phonemes can be transmitted by signals of narrow bandwidth over submarine cables or satellite communication links and can be restored to normal speech by means of a correlator including reference heads which are the time inverse of the heads which produce the coded phonemes. These heads are used as recording heads to which the coded pulses corresponding to phonemes are applied. The recording heads lay down on the recording drum or disc a pattern which develops in a conventional play back head a voltage whose time variation duplicates the original speech.

Abstract: 1,233,511. Lightning arresters. GENERAL ELECTRIC CO. 15 April, 1969 [13 May, 1968], No. 19121/69. Heading H2H. A spark gap assembly, for use with either A.C. or D.C. systems, comprises a number of series-connected gaps, across some of which a trigger gap is connected. Using grading impedances and non-linear resistors, the assembly is designed to give a high ratio of reseal to sparkover voltage. In the embodiment of Fig. 1, the main sparkgaps 7-11 are arranged in two groups A and B between a transmission line 1 and a grounded non-linear resistor 5. Across the group B, there is connected a trigger gap 20 and a coupling circuit 21. A pre-ionizer gap 25 is arranged close to the trigger gap. In operation, when a highvoltage surge occurs on the line 1, the impedance of a non-linear resistor 26 decreases, and the pre-ionizer gap 25 sparks over, supplying ionization for the gap 20, which subsequently sparks over itself if the surge voltage reaches a level approximately twice the normal line voltage. The sudden breakdown of the gap 20 causes the full surge voltage to be placed across the group A of main gaps which now break down successively. The full voltage now appears on capacitor 21a and is transmitted to the group B, all the gaps of which now spark over allowing the surge to discharge to earth through the resistor 5. At the same time, the trigger gap 20 is restored. When the surge has discharged, a follow current will pass through the assembly, but due to the presence of resistor 5 and to the action of coils 12 lengthening the arcs in the main horn gaps, a voltage builds up and the assembly is resealed. The reverse voltage is graded by impedances 14, 15 so that individual gaps do not restrike.
