Abstract: A process for the recovery of zirconium from an aqueous acid solution by solvent extraction is disclosed. The process includes contacting the aqueous acid solution, which may also contain titanium and other metallic impurities, with an organic solution of a water-insoluble organic solvent and a suitable dialkyl-organophosphinic acid whereby zirconium and hafnium are selectively extracted from the aqueous solution into the organic solution with only minor amounts of coextracted titanium and other metallic impurities. The zirconium and hafnium may be subsequently stripped from the pregnant organic solution by contacting the solution with an aqueous ammonium carbonate solution whereby the zirconium and hafnium are selectively extracted from the organic solution into the aqueous ammonium carbonate solution with only trace amounts of coextracted titanium and other metallic impurities. A high purity zirconium/hafnium oxide may subsequently be precipitated from the pregnant aqueous ammonium carbonate solution by a controlled heating process.

Abstract: A no-moving parts pulverizer (19) and classifier system (15) reduces materials to one hundred fifty microns to less than ten microns using superheated steam or any gas capable of being compressed and expanded thru machined orifices. The resultant size reduction depends upon the classifier gas rate and pressure, the pulverizer gas rate and its pressure. These combinations control and regulate miximum particle size, average particle size and the mix of gas and solids in process. 
     The feedstock enters the classifier chamber (15) by auger (12) or similar manner as long as the feeder maintains a positive seal. The classifier chamber (15) separates the feedstock by size and particles of a predetermined size exit (32) the system in a specific ratio of gas and solids. The feedstock larger than specified exit the base of the classifier (15), split into two equal streams (20A, 20B) and accelerate thru the pulverizer (19). The reduced feedstock exits (13) the pulverizer (19), mixes with incocming feedstock (10) and again enters the classifier (15). 
     The system is controlled using pressure, temperature, feedrate or any combination of the three. Other control methods can be used if any one of the three are part of the control circuit.

Abstract: There is described a prosthetic alignment device comprising at least two co-operating members (1,2) having opposing spherically curved faces. The faces include means for defining a direction of relative movement of the co- operating members and for calibrating that movement. The means for defining and calibrating comprise a row of teeth (14) on the said curved face (a) of one member (1) and a corresponding row of indentations (5) on the said curved face (b) of the opposing member (2). The rows of engaging teeth and indentations define the direction one member is to move relative to the other. The pitch of the teeth gives a pre-determined angle of adjustment of the two co-operating members, and by counting the number of teeth or indentations visible the adjustment of the two members and consequently the alignment of the prosthesis can be immediately calculated.

Abstract: A semiconductor memory circuit includes therein a bias voltage generator which produces a bias voltage to be supplied to a control gate of a field effect transistor (FET) which forms a part of each memory cell in the semiconductor memory circuit. The bias voltage generator is comprised of a bias voltage generating source which is sandwiched by first and second FET's. The second FET operates to stop a driving current flowing through the bias voltage generating source, in a standby mode, and the first FET operates to produce an output voltage near to the bias voltage. The bias voltage is generated by the bias voltage generating source when both the first and second FET's are turned ON, in an active mode, and the driving current flows therethrough.

Abstract: There is disclosed an encryption apparatus which apparatus functions to raise a large unsigned integer (B) indicative of message data to a large unsigned integer power E, modulo a large unsigned integer M with each of said integers being as large as N bits wherein the resulting large unsigned integer C is adapted for transmission over an insecure communications channel. The apparatus may likewise operate on a received integer C to recover the decrypted message B. The circuitry includes first logic means which is responsive to the large unsigned integer (B) for successively squaring said integer including means for reducing said squared integers successively by a given modulus M to provide at an output a first value indicative of said squared integer as reduced by said given modulus. selectively operated gating means are coupled to said first logic means and operates to receive bits of a given exponent power E. The gating means applies selected bits of the exponent power to second logic means which are controlled by said gating means to provide the product of said first value as further modified by modulus means for providing at its output the large unsigned integer for transmission over the insecure communications channel. The first and second logic means are constructed such that the required circuit size to perform the computation is significantly reduced in complexity resulting in increased speed together with a substantial reduction in cost.

Abstract: On the transmitting side of a facsimile system, a preprocessor (14) obtains a predictive picture signal (x̂ij) of a pel (i, j) taking account of predictive picture signals of pels prior to the pel (i, j) which have been previously obtained. A two-level transposition signal (d ij ) is generated in accordance with the predetermined on the basis of the result of a first comparing step carried out by a first comparing means (145) comparing an actual picture signal (x ij ) with a dither threshold (t ij ) stored in a memory (143) and on the basis of a second comparing step carried out by a second comparing means (147) comparing the predictive picture signal (x  ij ) with the stored dither threshold (t ij ). The thus obtained transposition signal (d ij ) is encoded by means of a MH or MR encoder (16) and transmitted to a receiving side of the facsimile system. 
     Compared with the conventional case in which a dither signal (z ij ) itself is encoded and transmitted, the transposition signal (d ij ) can be considerably compressed when it is encoded for transmission by means of the MH or MR encoder (16).

Abstract: For the powder-metallurgical production of aluminium-based semifinished products, gas-atomised aluminium alloy powders are used. The oxide contents and/or hydroxide contents of such powders lead to blister formation and a porous microstructure in the semifinished product. Especially high-strength alloys containing magnesium and/or lithium, which are heat-treated above 400 DEG C, suffer pronounced embrittlement, if the oxide content on the particle surface exceeds certain limits. These limits cannot be adhered to by conventional vacuum processes and equipment. According to the novel process, and using the corresponding equipment, high-strength aluminium alloys having a blister-free structure and low embrittlement are to be produced by powder-metallurgical means. According to the invention a blanketing gas flows at a minimum velocity of 0.2 m/s around all sides of the gas-atomised alloy powder at temperatures between 400 and 550 DEG C. This produces a dynamic pressure gradient which promotes the transport of the oxides/hydroxides away from the powder. The powder thus treated is hot-formed and rapidly cooled immediately after forming. This gives products of a blister-free structure having low embrittlement and a very low content of hydrogen and oxides. Power-metallurgical production of pressed, forged or rolled products based on high-strength aluminium alloys.

The General Formulas (I) to (VII) are described in the specification.   Disclosed is also a method for processing a light-sensitive material by using the bleach-fixing solution.   
     By use of the bleach-fixing solution of this invention, rapid processing of the light-sensitive material is enabled without a generation of ammonia gas, because the bleach-fixing solution can delay the occurence of the precipitation even during storage with time to attain a stable bleach-fixing performance, and it can improve the bleach stain at a non-image portion of a light-sensitive material when the processing with low replenishment is carried out.
