Abstract: To diagnose diseases in patients, a protein complex, RhC. is prepared from horse serum by precipitating a white bowder from the serum at a pH of 5.5 and processing to remove lipids at a pH of 8.2 using Tris-HCI as the buffer. It in- bludes two components bound together to provide a molecular weight of 280,000 and having characteristics of a rheumatoid factor and a Clq-like subcomponent of the complement. The protein complex is incubated with human serum or plasma and then precipitated by dialysis against a high pH buffer (0.5 M Tris-HCI pH 8.2). When precipitated, it co-precipitates the immune complexes from the human blood serum without substantial monomeric immunoglobulin to quantitatively isolate immune complexes from serum Immunological assays then determine how much immune complex and what kind were in the serum.

Abstract: The gate (6) of a double heterojunction FET is formed of heavily doped semiconductor material of the same conductivity type as that of the source and drain regions (3, 4). An ohmic contact (7) can be made to the gate. The gate (6) and channel regions of the FET have the same barrier height relative to an intervening semiconductor layer (5). If the intervening semiconductor layer (5) is undoped, the device has a threshold voltage of near zero volts. The threshold voltage can be increased or decreased by adding an n or p type dopant to the intervening semiconductor layer (5).

Abstract: A valve body includes a chamber for the flow of fluid between an inlet and an outlet thereto. The chamber includes an upper portion with an opening therethrough and a lower portion including a valve seat between the inlet and outlet openings. A valve seat insert is positioned in the valve seat and includes a pair of oppositely positioned ports communicating with the inlet and outlet openings. The valve seat insert is compressed to prevent leak paths between the valve body and the valve seat. A bonnet is positioned in the chamber upper portion and is connected to the valve body and extends upwardly therefrom. A stem is positioned for longitudinal movement in the bonnet and includes a lower portion for sealingly engaging the valve seat insert. An upper portion of the stem is connected to an actuator which extends upwardly and out of the bonnet. The stem upper portion is threadedly connected to the actuator, and the actuator is threadedly connected to the bonnet. The lead of the threaded connection between the stem and the actuator is in a direction opposite to the lead of the threaded connection between the actuator and the stem such that rotation of the actuator generates rapid nonrotational, longitudinal movement of the stem between the open and closed positions of the valve. A bellows surrounds the stem below the actuator to provide a seal around the stem between the valve body and the actuator. A stem restraining washer is clamped on the valve body in surrounding relation with the stem. Flats on the stem engage flats of the washer to prevent rotation of the stem upon rotation of the actuator to open and close the valve.

Abstract: Water-displacing compositions based on fluorocarbon solvent FC-113 (1,1,2-trifluoro-1,2,2-trichloroethane) and certain surfactants are provided. These solutions serve to displace water from a broad range of substrates, including metals such as stainless-steel, aluminium alloys and brass, as well as from glass and ceramic surfaces such as lime glasses, borosilicate glass, unglazed alumina and fired alumina. In addition, these compositions do not form emulsions with the displaced water. This latter property is important to efficient water removal by decantation when the drying solvent is used in commercial drying processes and apparatus. 
     The surfactants are chosen from a combination of: (a) the isopropyl amine salt of a dodecylbenzene sulfonic acid; (b) 2,4,7,9-tetramethyl-5-decyn-4,7-diol combined with an aliphatic primary alcohol in the range of hexanol to dodecanol; and (c) certain aliphatic esters of polyphosphoric acid, in the free-acid form. This combination of ingredients, in appropriate weight relationships to each other, is present in the dewatering solution at a total weight of about 0.5 percent based on the fluorocarbon solvent.

Title: Sputtered semiconducting films of catenated phosphorus material

IPC: C30B23/08
Filed: 1984-06-28
Abstract: A process for the production of a semiconducting catenated phosphorus film characterised in that it comprises sputtering a thin film thereof onto a substrate is disclosed. 
<??>The present process may be applied to the production of semiconductor devices. Referring to the accompanying illustrative drawing, a sputtered film 22 may be used in a sandwich configuration on a glass substrate 24 with a metallic lock contact 26 and metal dot top contacts 28. 
<??>For example, amorphous and polycrystalline films of KP15 may be formed by RF diode sputtering targets of KP15 and excess phosphorus in an argon phase. Substrate temperatures up to 280-300 DEG C provide amorphous films. Higher temperatures provide microcrystalline or polycristalline films. These films have high resistance and may be used as the insulator in MIS devices employing III-V semiconductors. Co-sputtering with nickel increases the conductivity of the films from approximately 10<-><1><0> (ohm-cm)<-><1> to 10<-><2> (ohm-cm)<-><1>; only reduces the optical gap by 0.2 eV; and reduces the activation energy from 0.8 eV to 0.2 eV; the nickel content varying from 5-15%. Substrates include glass, silicon, tantalum, stainless steel, gallium phosphide and gallium arsenide, and glass metallized with metals, such as titanium, nickel and aluminium. Double diode electrical characteristics have been observed in devices formed on metallized glass substrates having co-sputterred thereon thin film polyphosphides and nickel with nickel and titanium top contacts. 
<??>The present invention represents an advance over the prior art.

Abstract: A rotating disk electrode system operates at constant speed in a solution whose metal ion concentration is held constant at multiple concentrations within a range of concentration. The current at the working electrode (16) is recorded, while the potential at the working electrode is swept by potential source (20) at a predetermined rate for each of the concentration values. The diffusion limiting current is determined by recorder (24) for each of the concentration values. Then the rotating disk electrode system is operated continuously in a metal plating bath (12) whose metal ion concentration can vary. A voltage applied to the working electrode produces a current at the electrode whose magnitude is compared to the values of the previous calibration to determine the current metal ion concentration. Alternatively, a rotating disk electrode system is operated over a range of speeds in a solution whose ion concentration is held constant over a range of concentration. Current at the working electrode is measured for a given electric potential applied to the working electrode. In this way, a calibration relationship between the current at the electrode and the range of metal ion concentrations is established which can be used with current measured in the plating bath under the same conditions as those that established the calibration curve to predict the concentration of the bath. ;
