Abstract: ABSTRACT OF THE DISCLOSURE            In radiotherapy use is made of apparatus of the type in which a chain of balls comprising radioactive balls and inert spacer balls is moved pneumatically to and from an applicator tube within the patient, the spacer balls are made of a material such as nylon which is softer and less dense than the radioactive balls, and is radiographically transparent.  This reduces wear and tear on the radio-active balls and facilitates control of dosage and moni-toring of the treatment.  The balls are sorted after use by means of a radiation detector.  The ball chain has a larger diameter end ball of ferromagnetic material, which blocks air flow through the applicator when correctly located therein, and whose position can be verified by an induction air coil.  By assembling and storing the chain in a storage tube having two air inlets, respectively above and below the end ball, and choking the lower inlet, air may be selectively applied to the inlets to expel the chain from the storage tube either with its end ball for transport to the applicator tube, or without its end ball for sorting.  Use of the lower inlet alone enables pres-sure retaining the chain in the applicator to be maintained only in the absence of send out air flow through the applicator tube, thus enabling malfunctions to be detec-ted.

Abstract: ABSTRACT OF THE DISCLOSURE A process for recovering the metal values from spent hydroprocessing catalyst particles.  The metal values will include at least one metal of Group VIII of the Periodic Table and at least one metal of Group Vb or Group VIb of the Periodic Table.  The spent catalyst par-ticles are first roasted at between 400°C and 600°C and then contacted with a first aqueous solution of ammonia and an ammonium salt forming a first pregnant liquor.  The once-leached spent hydroprocessing catalysts are contacted with a second aqueous solution of sulfur dioxide forming a second pregnant liquor.  The metal values are precipitated from the second pregnant liquor with hydrogen sulfide and the precipitate is roasted with unroasted spent hydropro-cessing catalysts.  The metal values of Group Vb and Group VIb in the first pregnant liquor are transferred into a first organic solution by liquid ion exchange.  The first organic solution is stripped by an aqueous strip solution and the metal values separated by sequential precipita-tion.  The metals of Group VIII are separated and purified by serial liquid ion exchange.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved  receptor-reradiator, for use in a surveil-lance system employing a carrier frequency of UHF or higher in combination with a low frequency electrostatic field signal to be modulated on the carrier signal by the reradiator, is provided by an antenna frame wherein the metallic foil of which it is made is divided into three parts.  The first part is U-shape of substan-tially one width and joins to a central portion of substantially reduced width which is predominantly inductive at the carrier frequency.  A semiconductor diode, preferably a Schottky barrier diode or PIN switching diode, is connected in said central portion in series therewith.  The opposite end of the central portion joins to an enlarged rectangular portion.  At the low frequency the component has effectively two capacitive arms, one on each side of the diode, of different surface area to ensure bias signal for the diode.  However, at the carrier frequency, the central portion has a high inductive reactance which, in conjunction with the inductive reactance of the U-shape portion, tunes to resonance the total capacitance of the component including that of the diode.  The parts are proportioned such that the diode sees at the carrier frequency an inductance on one side and a capacitance on the other side.
