Abstract: 1461202 Annealing nickel-titanium alloys TEXAS INSTRUMENTS Inc 10 Dec 1974 [21 Dec 1973] 53344/74 Headings C7A and C7N An alloy containing by 50-58 wt per cent Ni and balance Ti is maintained under a tensile stress of 30,000-100,000 p.s.i. while it is annealed at a temperature above (preferably about 50C above) the temperature at which a first diffusional phase transformation occurs above the martensitic transformation range, that limiting temperature being identified by the incidence of a negative slope in the graph of electrical resistivity v. temperature. The alloy may be in wire form which is passed continuously through a hot zone. The process both increases tensile strength and reduces the tendency to relaxation on cycling through the martensitic transformation. The product may have a tensile strength exceeding 175,000 p.s.i., martensitic elongation activity of at least 2 per cent under a tensile stress greater than 100,000 p.s.i., and is resistant to fatigue failure for #10<SP>6</SP> cycles through the martensitic transformation under a stress such that the activity is 2 per cent. As exemplified a 54.3 per cent Ni alloy showed a first transformation temperature of 375C and was annealed at 425C under 35,000 p.s.i. stress.

Title: Process for removing ammonia from solutions of oxime-metall chelate
IPC: C07F1/00

Abstract: 1453859 Removal of ammonia from solutions of oxide-metal chelates KENNECOTT COPPER CORP 20 Nov 1973 [20 Dec 1972] 53745/73 Heading C1A Ammonia is removed selectively from an organic solution containing ammonia, nickel and/ or copper and a chelating oxime to obtain a solution having less than 50 mg. ammonia per litre by contacting the solution counter-currently with an aqueous solution of ammonium carbonate, ammonium bicarbonate, alkali metal bicarbonate or a mixture of two or more thereof having an ammonia concentration less than that which would be in equilibrium with 50 mg. per litre ammonia in the organic solution, effecting ammonia transfer to the aqueous solution without substantial emulsification of the latter in the organic solution, and separating the effluent organic solution from the aqueous solution. The process is preferably operated with a mole ratio of ammonia in the incoming organic solution to carbonate and/or bicarbonate in the aqueous solution, prior to contact between the two solutions, such that 1-4 scrubbing stages reduce the ammonia in the effluent organic solution to less than 50 mg. per litre. The effluent organic solution may then be contacted with an aqueous sulphuric acid solution, or an ammonium sulphate/sulphuric acid solution, having a pH sufficient to prevent metal being stripped from the organic solution, or with water, to remove substantially all (e.g. to less than 5 mg./litre) of the ammonia. A number of aliphatic saturated and unsaturated hydroxy ketoximes and of alkyl substituted ortho-hydroxy benzophenoximes are listed as suitable oximes; the organic medium is for example kerosine. The process of the invention forms part of a method for recovering nickel and/or copper from aqueous ammoniacal solutions, such a solution being extracted with an organic oxime solution to obtain the chelate solution here used as starting material; the effluent organic solution from which the ammonia has been removed by the present process is stripped with aqueous acid e.g. H 2 SO 4  to recover one or both metals and the latter are obtained by for example electro-winning from the aqueous acid.

Abstract: 1318673 Data processing systems INTERNATIONAL BUSINESS MACHINES CORP 22 Nov 1971 [10 March 1971] 54058/71 Heading G4A A plurality of processors are connected to a common element e.g. a store, through a common channel which includes circuits for timing the transmission of data through the channel by selectively employing timing signals from individual processors. When a processor requires access to the common element it issues a start signal, and if the element is not busy, clock signals from that processor are selected to time the transmission through the channels. A subsequent access request by a different processor before the common element becomes free results in the clock signals from the first processor being used for the data transfer between the second processor and the common element. Should two start signals from different processors coincide when the common element is not busy, a processor clock different to that last used is selected.

Abstract: 1,106,200. Digital engine indicator. H. LIST. 21 Dec., 1965 [25 Jan., 1965], No. 54194/65. Heading G4H. The area of the pressure/travel curve of an internal-combustion engine is measured by apparatus including a pressure transducer 1 applying a proportional signal to a comparator 3 an electromagnetic pick-up 7 actuated at intervals proportional to piston travel to trigger a sawtooth generator 13 giving a second input to the comparator, pulses being gated into a counter 14 for the period before equality is reached. The head 7 senses magnetic marks on a disc 5 rotating with the engine shaft. The duration signal from comparator 3 represents the pressure in that particular strip of the curve. Pulses from an oscillator 16 are gated 15 to counter 14. The engine shaft also carries deadcentre marks 17 sensed by a second head 18 to produce four stroke pulses in each cycle. These pass to a 5- stage shift register 21, the first four stages of which control the counter 14 so that the counts produced during the first and third strokes are added and those produced in the second and fourth strokes are subtracted. The final contents of the counter give the area of the indicator diagram. Instead of using a reversible counter, two counters may be used, the values being subtracted afterwards. The apparatus may be designed to integrate more than one cycle.

Preferably the wave-modifying structures gives a cross-correlation function between object and reference waves approximating #-functions. The mean intensity distribution of the light-scattered by each region 5, 6 is uniform at the hologram record plate. It is also preferred that when illuminated the central axes of the intensity distribution of light from each region intersect in the plane of the hologram record plate. The light-wave modifying structure may be a rotationally-symetrical structure or may be a statistically random light-wave structure having the properties of a ground glass plate. In this latter example laser light is scattered by a surface of uniform roughness; a photographic plate is exposed many times to this distribution with a shift between exposures. The exposed plate may be bleached or copied on to photo-resist. This plate may be located on the front of the plate 4 or, if the areas not having the light structures on the developed photographic plate are made opaque it can be used as the plate 4. The hologram may be used to produce multiple reduced-size images of an object.

Title: Method of and instrument for determination of the size of particles in a turbulently flowing fluid stream
IPC: G01N15/02
Filed: 1974-08-29
Abstract: 1485750 Measuring particle size electrically NATIONAL RESEARCH DEVELOPMENT CORP 29 Aug 1974 [29 May 1973] 55025/72 Heading G1N An indication of particle size or mean particle size in a turbulently flowing fluid stream containing the particles is obtained from a measurement of the instantaneous particle density at a station of the stream. It is shown that the velocity response of a particle in the stream when excited by the instantaneous velocity of the fluid is that of a first order system having a cut-off frequency given by f c  = (2K 1  IID)<SP>-</SP><SP>1</SP> Hz where K 1  is a  constant derived from the viscous drag coefficient and the difference in densities of the particles and fluid and D is the particle diameter. Since it is not practicable to measure the cut-off frequency directly use is made of the fact that the velocity spectrum of particle turbulence also exhibits the cut-off frequency and since in a turbulent flow the fluctuations in particle velocity are directly related to the fluctuations in instantaneous density of particles in a given volume of the stream this density may be used to obtain the cut-off frequency. Density may be measured by capacitive, tribo electric or conductive arrangements. Fig. 4. The resistance changes of the conductivity path between an electrode 1 and conducting pipe 2 due to the variations in the average number of particles near electrode 1 and being related to the velocity fluctuations of the particles is monitored by conductivity transducer 3. The output M (t) of transducer 3, whose amplitude varies with concentration, has a handwidth from f o  to f c  whose area varies with concentration. (See inset of Fig. 4). A.G.C. circuit 4 converts m(t) to a constant mean output amplitude Z(t) which contains all the information about the velocity of the particles but not the undesired information relating to mean concentration. The output Z(t) is then applied to respective high pass and low pass filters 5, 6 with a cross-over frequency f 1 . The mean amplitudes E 1 , E 2  of the filter output signals are measured by integrating A.C. voltmeters 7, 8 so that E 1  is equal to the area under the AGC spectrum between f 1  and f c  and E 2  is equal to the area between f o  and f 1 . Divider 9 then gives an output representative of the particle size. Auto-correlation Fig. 5 (not shown). Since the auto correlation function of a signal conveys the same information as the frequency spectrum of that signal and the cut-off frequency f c  of the frequency spectrum is proportional to the reciprocal of the cut-off point of the characteristic auto-correlation this latter can be determined as a function of particle diameter. In practice this is done by measuring the area under the normalized auto-correlation curve. If the fluid velocity has a significant variation then the fluid velocity is measuring using a crosscorrelation method which is used to compensate the Fig. 4 arrangement, Fig. 6 (not shown).
