Abstract: 643,594. Drag line scrapers; lever load-handling machines. DEVAUX,G. Feb. 24, 1948, No. 5423. Convention date, March 12, 1947. [Classes 78 (iii) and 78 (iv)] [Also in Group XXI] A scoop arm load-handling apparatus is mounted at the rear of a wheeled vehicle and comprises a scoop 3 secured at points 4, 5 to the forked ends of an arm 6 pivotally mounted at 7 on a post 8. A second arm 9 is also pivotally mounted on the post 8 and its end 11 bears against the pivoted rear wall 12 of the scoop 3 which is raised by a winch cable hauling at 15, or a hydraulic jack pushing at 14, on the arm 9. As the arms 6 and 9 rotate there is relative movement of their ends, the end 11 riding upwardly over the rear wall 12 of the scoop until the arm 9 makes contact with a stop 16, after which further rotation of the arms permits the wall 12 to pivot, the contents of the scoop discharging through the space between the bottom and rear wall of the scoop. In a modification the scoop is pivotally mounted on the arm 6 and the rear wall is formed integrally with the scoop. As the arms rotate, the end 11 of the arm 9 rides upwards over the rear wall until a point is reached when the scoop tilts forward due to the weight of its contents and discharges. To prevent overturning of the bucket during the initial lift, a locking device secures the bucket to the arm 6, it being released by the arm 9 at its upper position. To remove a load from deep excavations, the scoop is used as a drag scraper, it being hauled up by cables passing over pulleys on the arm 6 and positioned at the end of the arm where it is locked in position prior to lifting. The scoop may be replaced by a forked implement.

Filed: 1975-02-10
Abstract: 1508831 Bandwidth companders J A ADCOCK 10 Feb 1975 [11 April 1974] 5544/75 Heading H4R An audio bandwidth compander halves the original audio frequencies and reduces the amplitude envelope to the square root, filters and phase equalizes the resultant, then transmits it as a double sideband suppressed carrier modulation, and detects the modulation in a square law detector which restores the audio to its original form. In the halves of Fig. 1 the audio A Sin# and its quadrature component A Cos# are squared, added and square rooted at 102, 103 to extract A which is added at 105 to A Cos# then square-rooted at 106 to extract a D.C. signal F proportional to #A Cos #/2. Alternate half-cycles of F and its inverse are gated by switch 107 at alternate zero crossings of A Sin# to produce the output G which is again proportional to #A Cos #/2 but alternates. At the receiver, this signal is simply squared and the identity A Cos<SP>2</SP>(#/2)=¢(A+A Cos #) considered whereby low pass filtering removes A and a signal proportional to A Cos # results.

Title: Improvements in thread tensioning devices
IPC: B65H59/06
Filed: 1930-02-19
Abstract: 341,314. Yarn-delivery apparatus. DURAND, M. P., 31, Chemin de la Croixde-Fer, St. Germain-en-Laye, France. Feb. 19, 1930, No. 5594. Convention date, Nov. 25, 1929. [Class 120 (ii).] A tension regulator for threads drawn axially from yarn packages comprises a rotating arm serving as a thread guide, which is braked in accordance with the tension in the thread so as to maintain constant tension. The thread 8 is led over the guide 6 and under the pulley 16 which is attached to one end of the bell crank lever 14. Excessive tension in the thread causes the pulley 16 to rise and so move the slide 13 and braking element 7<1> against the spring 11, thus diminishing the braking effect between the brake 7<1> and bobbin support 2. The screw 12 allows the effect of the spring to be readily adjusted. The whole device is detachable and is held in place by a spring catch 18 engaging a slot in the spindle 4. A modification is described wherein the thread is guided downwards through the centre of the bobbin. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a form of tension device consisting of a rotatable conical weight which carries a thread guiding arm and rests on a conical seating in the top of the bobbin, the thread passing through the guide at the end of the arm, towards the centre of the bobbin, through an eye attached to the weight, and then vertically upwards, so that, when the thread tension increases, it tends to lift the weight off its conical seating, and so decrease the frictional resistance offered to the rotation of the weight and guide arm. This subject-matter does not appear in the Specification as accepted.

Title: Method and apparatus for measuring small reactance or impedance

Abstract: 982,837. Measuring impedance. KABUSHIKI KAISHA TSUGAMI SEISAKUJO. Feb.16, 1961 [Feb. 25, 1960; May 13, 1960; May 16, 1960; Oct. 12, 1960], No. 5792/61. Heading G1U. An apparatus for measuring small values of impedance or reactance comprises a high frequency power source OSC, a first resonant circuit L1C1 coupled to the source, a second resonant circuit L2C2 coupled to the first resonant circuit, a detecting arrangement (including microammeter G) coupled to one of the circuits and an arrangement for coupling a small impedance or reactance (e.g. #CX) to one of the resonant circuits, the coupling between the first and second circuits being given by the following relationship where Q 2  = #C 2 R 2 ,# being the angular frequency of the source, C2 the value of the capacitor of the second circuit, R 2  the value of the equivalent parallel circuit representing the total loss of the second circuit, Z 0  the value of capacitor or mutual inductance of elements coupling the circuits and Z 2  the value of capacitor or inductor of the second circuit. To set up the circuits with this coupling a switch S1 in parallel with the second circuit is utilized. With this switch closed the capacitor C1 is adjusted to give a maximum in the detector circuit, and then with it open capacitor C2 is adjusted to give a maximum in the detector circuit. This ensures that variations in physical conditions or operating frequency do not disturb the working point of the circuit. With the detector circuit shown, and with identical components in the first and second resonant circuits, when small capacitance #CX to be measured is connected across the second resonant circuit, the detector output indicates this value. A similar arrangement but using two sets of cascaded resonant circuits with two detector windings coupled in opposition to a transformer is also described (Fig. 3 not shown). The circuits may be adapted for measuring resistive loss. After the initial stages of decoupling the second resonant circuit and tuning C1 for maximum in the detector circuit and then coupling the second circuit and tuning C2 for minimum in the detector circuit, the reactance in the second circuit is detuned by an amount #C given by #.#C.R 2  = 1. Thereafter C1 is again adjusted to give a maximum in the detector circuit. Under those conditions if an impedance is connected to the second resonant circuit the change in the detector output will indicate the resistive component or loss of that impedance (Figs. 6, 8, 10, not shown).

Abstract: 696,919. Resilient containers. LEMOINE, R., and LEMOINE, S. March 9, 1951, No. 5810/51. Class 66 [Also in Group XXIX] A container for a liquid or pasty substance comprises a reservoir of resilient dilatable material such as rubber in which the substance may be stored under pressure due to the dilation of the walls and from which it is expelled by the re-contraction of the walls when the mouth of the reservoir is uncovered together with a control valve which normally maintains the reservoir mouth closed. In one embodiment a rubber reservoir a is loosely held inside a casing f having an enlarged top portion b which comprises one part of the outlet valve. A cap c having a central aperture through which the neck of the reservoir slightly projects is free to rotate on the part b but is urged by two straight parallel springs d (e.g. of piano wire) into a position in which the springs d squash and seal the reservoir neck. Rotation of the cap c as by finger pressure on the portion c<SP>1</SP> containing the ends of the springs allows the substance to exude. In an alternative form of valve (Fig. 6) the reservoir is attached to an outlet tube g having an orifice k which may be' closed from inside by a screw or spring-loaded plunger h covered by a leak-proof rubber cap j. In this arrangement withdrawal of the plunger by means of handle i releases the container contents. The reservoir may be provided with a constriction a<SP>2</SP> to prevent too rapid discharge of the substance and may be refilled by forcing in a fresh charge of substance under pressure with the valve held open.
