Title: Determination of yield elongation during tensile testing
IPC: G01N3/06
Filed: 1971-04-19
Abstract: 1309204 Measuring yield elongation electrically CENTRE DE RECHERCHES METALLURGIQUESCENTRUM VOOR RESEARCH IN DE METALLURGIE 19 April 1971 [5 March 1970] 23197/71 Heading G1N [Also in Division G4] A method of determining the yield elongation of a metal test-piece in a tensile-test comprises comparing a signal representing # log # with a further signal representing P. # log # where #, # are true stress, strain respectively and P is a given value predetermined in accordance with the metal and equal to the value of the angular coefficient # log #/# log # at which the end of the yield elongation range is reached, and recording the value of elongation at which equality is reached between the signals. The apparatus for determining the yield elongation of a mild steel test piece when connected to a tensile-test machine with means for measuring elongation,width, and load comprises a circuit in which elongation signals A are combined with a unity-representing signal, from a potentiometer 2, in a summator 3 connected to a function generator 4 producing a signal representing true strain # { = ln(1+A) of which the logarithm is derived in a function generator 5. Simultaneously a load transducer 12 produces a signal representing load, F, which is divided successively at 13, 15 by signals representing pre-test width and thickness of the testpiece to produce a signal representing the resistance to deformation <SP>F</SP>/ So , where So is crosssection area, which signal is multiplied by that from summator 3 representing (1+A) to derive true stress # of which the logarithm is derived in a junction generator 18. The value log e is fed via memory 7 and reversing module 8 to a summator 9 where it is combined with a reference value (log e), from a blocked memory 6 to produce a difference signal # log #. Similarly the log # signal is fed via memory 19, 20 and summator 21 to produce # log #. The difference # log # is compared in comparator 23 with a value P. # log # from potentiometer 22, where P is a number between 0À15 and 0À3 for mild steels. When the difference # log # equals P. # log e the output signal from the comparator 23 is fed to a memory 24 linked to the elongation transducer 1, so as to block the memory. The elongation memorized at the moment of blocking is the required yield elongation.

Filed: 1933-08-22
Abstract: 424,773. Television. NAKASHIMA, T., 4326, Nishiiba-cho, and TAKAYANAGI, K., 177, Hirosawa-cho, both in Hamamatsu, Japan. Aug. 22, 1933, No. 23386. [Class 40 (iii)] For synchronizing a television system employing a cathode-ray receiver 21 in which the vertical and horizontal scanning movements are controlled by devices 32, 33 for producing saw-toothed wave-form, both line and frame deflections are synchronized at the receiver by means of a single series of synchronizing impulses whose frequency is a submultiple of the line frequency and a multiple of the frame frequency. These are derived from apertures 4 or slots 4<1>, Fig. 2, (not shown) in the scanning disc, which influence a photocell 12, and modulate a carrier which also conveys speech signals from a microphone 10. A separate carrier is used for the picturecurrent signals from cell 5. At the receiver the synchronizing signals are applied to an independent local oscillator 29 whose frequency is equal to or a multiple of that derived from the cell 12. This frequency is a multiple of the frame frequency to which the oscillator 31 is tuned, and is a submultiple of the line frequency to which oscillator 30 is tuned; preferably it is the geometric mean of these frequencies. The outputs of the oscillators 30, 31 are applied to the generators 32, 33 of saw-toothed waves, which operate at linescanning and frame-scanning frequencies respectively. The switches 36, 37 are closed by hand at the moments when the phase relations are seen to be correct. In a modification Fig. 2, (not shown) the synchronizing frequency may be stepped up to a supersonic value by means of a frequency-multiplier. The frequency is at the receiver applied directly to the line-frequency scanning device, and the frame-frequency scanning device may be locked to the latter by a conductive connection or merely by juxtaposition.

Title: Radioactive polymers
Inventor: BRINDELL GORDON DWIGHT
IPC: C08F36/04
Filed: 1961-06-28
Abstract: A radio-active polymer comprises a polymerized ethylenically unsaturated hydrocarbon monomer and tritium.  The polymer is formed by subjecting the monomer to polymerization conditions in the presence of a polymerization catalyst and tritium.  The monomer may be ethylene, propylene, butene, styrene, methyl styrene, or a conjugated diolefin.  Preferred catalysts are mixtures of titanium or zirconium tetrachloride with amyl sodium, octyl sodium, parasodic tertiary butyl benzene, triethyl aluminium, tetraethyl lead, or diethyl zinc.  Polymerization may take place at room temperature to 200 DEG C. in the presence of a paraffin or cycloparaffin inert diluent.  In examples, a mixture of ethylene, hydrogen, and tritium is polymerized under pressure in the presence of n-hexane and either n-amyl sodium and titanium tetrachloride or triethyl aluminium and titanium tetrachloride. The polymers are useful as a constant source of beta radio-activity, for example as counting standards or tracers. To form a self-luminous material, a phosphor is incorporated in the polymer.
