Title: Improvements relating to reinforcement for mortar or the like
IPC: E04C5/06
Filed: 1954-08-18
Abstract: 766,277. Reinforced concrete. MARSDEN, A. Aug. 18, 1955 [Aug. 18, 1954], No. 24060/54. Addition to 752,874. Class 20(4) A reinforcement for mortar, or like structures, of the kind described in the parent Specification and built up from a series of steel strips 1 each of which is bent to form half hexagons which have sides 2, 3 and 4, and are separated by a length 5 of strip equal in length to a side 3, the sides 2, 4 being slightly shorter than the sides 3, is characterized in that the lengths 5 abutting the sides 3 are secured together to form a structure of honeycomb shape by means of staples 8 which are secured in a manner to permit the required amount of relative movement between adjacent strips 1. Pairs of holes 6, 7 are made in each length 5 and side 3, the arms 9, 10 of the stainless steel staples 8 being passed through the aligned holes 6, 7 'and then turned over. Holes 12 are made in the sides 2, 4 to permit the filling of mortar to join individual cells. If the surface for the reinforcement is flat the staples 8 should fit fairly tightly in their holes 6, 7, 'but if e.g. the reinforcement is to be part of a lining, or covering, for a pipe, or other curved surface, there must be enough play for the staples in their holes to permit the reinforcement to be bent to the required curvature.

Title: Improvements in methods for producing ultrasonic images
Inventor: TROMMLER HERBERT
IPC: G01H9/00
Filed: 1954-08-18
Abstract: 754,799. Ultrasonic inspection devices. VEB C. ZEISS JENA. Aug. 18, 1954, No. 24076/54. Class 118(2) A method of depicting objects with the aid of ultrasonic vibrations (especially for material testing purposes) wherein a relief-image is formed on the surface of a fluid is characterized by the additional formation upon said relief-image of a system of parallel bands or of concentric rings due to the production of interfering vibrations. This ensures that a flaw in the material, such as a shrinkage cavity through which no waves are transmitted is shown not only by its contour but by a void in the formation of interfering bands, as at 19 in the image of a circular plate 20 shown in Fig. 4. The image may be produced by situating the object 3 to be depicted between a sound transducer 4 and an image-forming lens 5 immersed in a coupling fluid 1 (e.g. water) in a contained 2. By reflection at an inclined glass plate 6 the lens 5 forms a reliefimage in known manner on the fluid surface 7. By means of a point source of light 8 and a window 11 in the bottom of the container 2 a Schlieren-type optical image is projected on to a screen 15. A thin foil 17 fixed in a frame that can be pivoted to make a small angle # to the surface of the liquid is interposed in the path of the ultrasonic waves to produce reflections within the wedge of fluid above the foil, thereby producing interference bands; the frame may be rotatable so that the parallel bands can be orientated to give optimum legibility of the image. Alternatively, the foil may be cone-shaped to produce concentric rings. In either case there will be an absence of the interference phenomenon at points where there are no ultrasonic waves, e.g., where defects occur in the material under examination.

A mixture containing molecules of various sizes, e.g. a polyethylene wax, is analysed using a chromatograph having two separation zones, one zone 14 being packed with material, e.g. a copolymer of divinyl benzene and styrene in the form of a gel, having a permeability limit with high resolution for high molecular size components and the other zone 27 being packed with material having a permeability limit with high resolution for low molecular weight components. The sample to be analysed, dissolved in a solvent, is passed through zone 14 and the effluent therefrom flows through cell 20 in detector 19, while pure solvent is passed through zone 27 and reference cell 30. The valves are then switched so that the sample stream flows through zone 27 and the solvent stream flows through zone 14. Detector 19 may be a differential refractometer, associated with a light .beam and two photo cells, which measures the difference in the refractive indices between the solution passing through cell 20 and the solvent passing through cell 30. The changes in refractive index corresponding to the relative changes in concentration are automatically recorded on a chromatogram, from which the various molecular sizes of the sample can be determined.
