Abstract: A subsea system including a frame including an intensifier, the intensifier providing structural support to the frame and capable of providing pressurized delivery fluid. The intensifier includes an intensifier chamber and a delivery fluid chamber separated by a piston, the intensifier chamber capable of receiving ambient pressure to provide a pressure on the delivery fluid through the piston. Also, a regulation system regulates the amount of ambient pressure communicated to the intensifier chamber to maintain the delivery fluid pressure substantially constant as the delivery fluid is depleted.

Abstract: A process of preparing a high bromide tabular grain emulsion comprising a dispersion medium and silver halide grains including tabular grains having {111} major faces and an aspect ratio of at least 2, which contain greater than 50 mole percent bromide, based on silver, and which account for greater than 50 percent of total grain projected area, where such tabular grains have an average aspect ratio of at least 5, the process comprising (i) in a grain nucleation step creating in a dispersing medium tabular silver halide grain nuclei containing parallel twin planes and (ii) in a grain growth step subsequently growing the tabular grain nuclei into tabular grains in a silver halide reaction vessel by adding a silver ion source and a halide ion source to the reaction vessel and precipitating silver halide onto the tabular grain nuclei, wherein thiocyanate ion is introduced into the silver halide reaction vessel prior to the addition of at least the final 10 mole percent of the total silver added to the

Abstract: A radiographic phosphor panel having oxosulfur functionalized polymer reducing agents. The phosphor panel has a support and a luminescent layer overlaying the support. The luminescent layer includes phosphor crystals, and binder. The oxosulfur functionalized polymer reducing agent is present in a concentration sufficient to substantially increase the photostimulated luminescence of the panel.

Abstract: A stabilized storage phosphor is disclosed intended to be exposed to X-radiation and subsequently stimulated to emit light is disclosed. The storage phosphor is the product of firing a combination of species characterized by the relationship:MFX.sub.1-z I.sub.z.uM.sup.a X.sup.a :yA:eQ:tDwherein M is an alkaline earth; X is selected from the group consisting of Cl and Br; M.sup.a is an alkali; X.sup.a is a halide; A is selected from the rare earths Eu, Ce, Sm and Tb; Q is selected from among metal oxides; D is selected from elements 23 to 28 of the periodic table; z is from 1.times.10.sup.-4 to 1; u is from 0 to 1; y is from 1.times.10.sup.-4 to 0.1; e is from 0 to 1; and t is from 0 to 10.sup.-2. The storage phosphor is stabilized against decline of photostimulated luminescence intensities by the inclusion of a monocyclic compound having a molecular weight of less than 350, exhibiting both acid and base dissociation constants of less than 10.sup.-5 at 25.degree. C.

Abstract: A radiographic phosphor panel having metal hydride stabilizer compound. The phosphor panel has a support and a luminescent layer overlaying the support. The luminescent layer includes phosphor crystals, and binder. The oxosulfur reducing agent can be added to the luminescent layer. The oxosulfur reducing agent has a concentration sufficient to substantially increase the photostimulated luminescence of the panel.

Abstract: A radiographic phosphor panel having binder compatible oxosulfur stabilizer and a preparation method. The phosphor panel has a support and a luminescent layer overlaying the support. The luminescent layer includes phosphor crystals, binder and an oxosulfur reducing agent. The oxosulfur reducing agent is dispersed within the luminescent layer on a substantially molecular basis. The oxosulfur reducing agent is a reducing agent for iodine. The oxosulfur reducing agent has a concentration sufficient to substantially increase the photostimulated luminescence of the panel.

Abstract: A phosphor composition which comprises oxygen and a combination of elements satisfying the relationship:[(Hf.sub.1-z Zr.sub.z).sub.1+x Sn.sub.1-x ].sub.1-y Ti.sub.2ywherein:x is in the range of from about -0.4 to 0.952y is in the range of from 0 to 0.5 andz is in the range of from 0 to 0.5These phosphors exhibit an orthorhombic crystal structure, and are useful in intensifying screens for producing a latent image in a silver halide radiographic element when imagewise exposed to X-radiation.

Abstract: A high reliability, low power fuse programmable DC level generator is implemented by providing at least one fuse in each branch of a resistive bridge such that programming of the level generator results in providing a blown fuse in the current path and as a consequence results in low current and low power under all operating conditions.

Abstract: A programmable logic circuit of the type known as a PAL (programmable array logic) incorporates a J-K register for each of the circuit outputs. The PAL includes a programmable array for generating products of selected input terms. The product terms available at the array outputs can be programmably allocated to either or both of the J and K inputs. The provision of isolating circuitry allows for simultaneous sharing of each product term by both the J and K inputs.

Abstract: A programmable logic circuit comprises a Programmable Array Logic (PAL) circuit in which individual product terms may be shared simultaneously by one or more of the circuit outputs. The product terms are selectively connected to the circuit outputs by programmable elements (such as a fusible link) to increase design flexibility. Isolating devices are provided in series with the programmable elements to allow for the simultaneous product term sharing.

Abstract: A test for the input and output circuitry of a logic array including means to disable the AND matrix and means selectively connecting the true and complement output of the input buffers directly to the output circuitry. Means are provided for activating and testing the exclusive OR in the output circuitry and selectively disable one of a combined input/output buffer pair.
