Abstract: An apparatus for ultrasonically measuring concentrations of stress in objects of interest. The apparatus includes an ultrasonic transducer array for propagating acoustic waves in an object of interest along a plurality of determinable directions and from a plurality of determinable positions. A time interval counter measures the time of flight of the acoustic waves along the determinable directions and from the determinable positions. The time of flight measurements are reconstructed into a map of the variations in acoustic velocity within the object. The changes in acoustic velocity are then mathematically converted into a map of stress concentration areas in the object of interest.

Abstract: A loading pendulum is arranged at the rear of one side of a firearm suspended in an elevating mass. The loading pendulum has two arms which can be swung in the traversing direction of the firearm, the first ends of which are supported for co-ordinated driving by means of drive shafts (13, 14) which are parallel to each other and, when the pendulum adjusts itself to the angle of elevation or depression of the firearm extend at right angles to said traversing plane, and second ends support a loading tray (10) in supporting shafts (15, 16) also at right angles to the traversing plane when the pendulum adjusts itself to the angle of elevation or depression of the firearm. The arms (11, 12) are arranged to achieve a position swung to the side and a swung-in position of the loading tray which moreover in a feeding position, which can differ as regards the angle of elevation or depression from said position when swung to the side, is arranged to receive an ammunition unit (30) from a loading table or the like and which is arranged to make it possible to swing in the ammunition unit to the extension of the axis of the bore of the firearm, with which the loading tray coincides at the swung-in position. Said arms have different lengths, and are arranged so that in the feeding position they will hold the loading tray obliquely. An ammunition unit which with its front ends extends at the front of the loading tray will then extend with said front parts at the side of the elevating mass.

Abstract: In a method for joining two pre-insulated pipes (1, 2) by bridging the gap between their insulating jackets with a jointing sleeve (6) and injecting insulating material (4a), such as foam plastic, in the space between the protruding ends (not shown) of the inner, medium-carrying pipes, a jointing sleeve (6) of transparent material is used. This makes it possible, without the use of special sensing equipment, such as ultrasonic sensing apparatus, to detect visually any faults (13) in the form of bubbles or voids that may occur in the insulating material (4a), and to repair such faults by drilling holes (14) through the jointing sleeve (6) into the faults (13) and filling the latter with insulating material through the holes. Seals may be provided between the ends of the jointing sleeve (6) and the outside of the two pre-insulated pipes (1, 2) by using narrow sleeves or rings (7, 8) of shrinkable material, that are inserted over one or both pipes (1, 2) before welding them together, and shrunk in place extending beyond the ends of the jointing sleeve (6).

Abstract: An atomic absorption spectrophotometer uses hollow cathode lamp assemblies (HCL1-HCL4) encoded by means of recesses and/or projections. The code represents one or more atomic elements corresponding to their resonant line(s). The presence or absence of the projections and/or recesses is read by corresponding code readers (CCR1-CCR4) feeding a microcomputer (MCP), which includes a microprocessor ( mu P) a read-only memory (ROM) and a read-write memory (RAM) to identify the elements. The read only memory (ROM) contains wavelength information at a location associated with each element, by means of which the microprocessor causes the correct operating current to be supplied by the lamp power supply (LPS) and causes the monochromator (MN) to be driven to the appropriate wavelength by the monochromator wavelength control (MWC). The projections and/or recesses may be formed in the lamp base or in a separate card attached to the lamp and inserted into a card reader.   <IMAGE>

Abstract: The invention relates to hot-rolled, thermally work-hardened reinforcing steel having a minimum yield strength of 500 MPa and universal suitability for welding in the dimensional range of 6 to 32 mm nominal diameter. The aim of the invention is the processing of scrap contaminated with Cr, Cu, Mo and Ni to give high-quality reinforcing steel. The object is to indicate an alloy composition which allows the alloy contaminations to be utilised for improving the use value in place of the addition of Si and Mn, hitherto provided in industry. The object is achieved by deviating from the standard prescription of an alloy tolerance for Si and Mn and lower permissible limits for Cr, Cu, Mo and Ni and, instead, weighting and limiting the total alloy influence of Si, Mn, Cr, Cu, Mo and Ni and allowing large tolerances for the individual elements, it being permissible for individual elements to be present in any desired quantity and combination within the new limits, while adhering to the value for the alloy equivalent and hence also for the total alloy influence on the yield strength, in accordance with the claim.
