Title: A method of and means for measuring bending moments, shearing forces and other stresses in a loaded structure
IPC: G01M5/00
Filed: 1933-10-06
Abstract: 423,452. Testing physical qualities of materials. IBANEZ, J. A. M. V., 55, General del Canto Street, Santiago, Chile. Oct. 6, 1933, No. 27539. [Class 106 (ii)] Comprises a method for the direct measurement of bending moment, shearing force, &c., in which a scale model of the structure is provided with a gap at the place of measurement and a measuring instrument is fixed to the model on opposite sides of the gap and adjusted to annul the deflection by producing an opposite bending moment &c. Fig. 1 shows diagrammatically the measurement of the bending moment of a member X, Y of a rigid frame. The two frames A, B of the instrument are rigidly connected at 1, 2 to the free ends of the member X, Y where the gap occurs. A flexible plate G is joined to A at 9 and to B at 8. A force P acting at the point a produces a bending moment at the middle point of the flexible plate G. A spring C is rigidly connected to A and B at 3, 4 and is deformed under the action of the bending moment. A spring D connected to the spring C at 5 bears against a screw T. Another spring E is fixed to A at 6 and to B at 4 and is connected to an indicating needle F, the free end of which is observed through a microscope H. Under the influence of the force P this free end moves to the right and is restored by moving the screw T an amount which is a measure of the bending moment. If instead of rigidly connecting the points 1, 2 of the instrument A, B to the free ends of X, Y, the points 10, 11 are connected as shown in Fig. 2, the longitudinal stresses in X, Y will produce a moment equal to their value multiplied by the distance between 10, 2 and 11, 1, the sum of which and the bending moment is measured by the instrument. To measure, shearing force, the instrument is connected to the model at the points 10, 14, Fig. 3, in which an angular arm L is joined to the frame B by an elastic plate J rigidly fixed to B at 2 and to L at 13, the arm L being also joined to a plate K rigidly fixed to an extension of B at 16. The instrument measures the sum of a moment comprising the product of the shearing force at 14 and the distance between 13 and the centre of J plus the bending moment. A constructional form of the instrument A, B is described as are suitable forms of structural members for building the model, such members being made of duralumin plate, wood, celluloid, &c. in standard sizes.

Filed: 1971-06-14
Abstract: 1346649 Ironing leather TURNER MACHINERY Ltd 14 June 1971 [15 June 1970] 27702/71 Heading C6C Leather is ironed by being urged against a heated surface by a pressure which is varied cyclically at a frequency of from 5 to 50 c. p. s. As shown, an endless belt 8 passing over rollers 10 and a drive roller 11 conveys a piece of leather 9 between a plate 1 with a tapered lead-in portion 3 and a plate 5 which has a resilient coating 6 of rubber or felt. The plate 1, which has means 4 for heating or cooling it electrically or by steam or water, is adjustably loaded and/or positioned by a hydraulic cylinder 2, and the plate 5 is connected to a vibratory device 7 which may comprise a flexible membrane subjected to a cyclically varying hydraulic pressure. Transport of the leather takes place during those phases of the vibratory motion when the pressure on the leather is not at its maximum, and to facilitate this the roller 11 is driven through a slip clutch, and the plate 1 and coating 6 may be faced with a low friction material. An additional roller 13, which may also be driven, ensures straight-line transport of the leather. A second belt above the leather may be provided, and this belt, preferably of steel for heat transfer from the plate 1, may run at a different speed from the belt 8. In a machine in which the vibratory frequency is 10 c.p. s. and the effective width of the plate 1 is 3cm. the leather transport speed may be 30cm/ sec., but it is preferred to use a wider plate so that successively ironed portions of leather overlap each other. The ironing tools and transport means may be inclined to the horizontal in which case the conveyer belt may be replaced by a stationary foil and the leather transported manually.
