Abstract: 888,576. Testing tensile strength of threads. COURTAULDS Ltd. March 19, 1959 [March 20, 1958; June 6, 1958], Nos. 8915/58 and 18094/58. Class 106 (2).  Apparatus for testing the tensile properties of threads comprises two clamps 1, 2, one fixed, the other movable, each clamp containing a continuous closed passage 3, these passages cooperating to form a single closed passage when the clamps are closest together, and means 21, 22 for producing a current of fluid in the passage. The clamps shown are stated to be of use in the testing apparatus described in U.S.A. Specification 2,442,150. Each clamp comprises a metal body provided with a U-shaped passage 3 around a bollard 5. Movable members 7 connected by stirrups 9 to pneumatic cylinders 11 act to clamp the thread against the bollards 5 when air is introduced into the cylinders. The clamp 1 carries a sleeve 15 and the clamp 2 has a corresponding tube 18 of smaller diameter. When the clamps 1, 2 are at their nearest positions, the sleeve 15 abuts a resilient buffer 17 provided on the clamp 2 and thus the passages 3, the sleeve 15 and the tube 18 form a continuous closed passage. Thread to be tested is fed into an inlet 19 and is drawn, by air passing through a Venturi 22 in a tube 21, through the closed passage, a measuring-device situated near the inlet 19 measuring off a suitable length. Air is then supplied to the cylinders 11 and the thread clamped as described, a test then taking place by tilting the track on which the clamp 2 is mounted, until the thread breaks. The whole test sequence is then repeated automatically. Specification 872,475 also is referred to.

Abstract: 772,010. Electric analogue calculating systems. COMMUNICATIONS PATENTS, Ltd. May 13, 1955 [March 29, 1954], No. 9055/54. Class 37. An integrating device comprises an electrolytic cell in circuit with a direct current representing in magnitude and sense the variable to be integrated, comprising an electrode to which metal is added or from which it is subtracted by electrolytic action in accordance with the value of the direct current; such electrode being included in a circuit independent of the electrolytic cell wherein an electric signal is established which is a function of the varying conductance of the electrode and thus of the integrated value of the input current, which is stored indefinitely as the electrode cross-section. A direct current analogous to the input variable is connected over terminals 1 to electrolytic cells 2, 3 containing a mixture of copper sulphate and sulphuric acid, with copper wire electrodes. Opposite ends of electrodes 5, 6 of the two cells are respectively shunted by fixed resistor 8 and variable resistor 9 and connected as adjacent arms of a bridge completed by the centre-tapped secondary of A.C. energization transformer 7. Initially, resistor 9 is adjusted for zero unbalance voltage across terminals 10, after which the variable input current is connected; copper then being deposited on electrode 5 and removed from electrode 6 or vice versa in proportion to the magnitude and sense of the time integral of the current and of the input variable and it is shown that this is also proportional to the unbalance voltage at terminal 10 in amplitude and phase sense. The transformer 7 is replaceable by a centre-tapped resistance connected across an alternating current source, and the electrodes and electrolyte may be respectively of gold or iron and a salt thereof. Unduly thin electrodes may be restored after protracted operation by adjusting resistor 9 to equality with resistor 8 and connecting the unbalance voltage through a phase-sensitive detector and subsequent amplifier to retroactively energize the circuit over terminals 1 when metal is removed from the thicker and deposited on the thinner electrode until the bridge is rebalanced at equal thickness.
