摘要： A circuit (42) for differential calorimetry includes a pair of resistance elements (36,38) in a bridge circuit (4,4). These resistance elements (36,38) are used for both heating and temperature sensing. Separate DC heating currents are effected in each element by high impedance current sources (118,120). An AC voltage is applied to the bridge for effecting the sensing function. In measuring AC differental voltage between the elements, the DC is filtered out. The filtered AC differential voltage is fed back to effect a current differential between the heating currents to null the differential temperature causing the differential voltage. A similarly filtered average AC voltage on the elements is compared with a reference voltage, and the resulting error voltage is fed back to control the average of the heating currents. A very high impedance current source includes a voltage-current transducer with an output of a heating current passed through a monitor resistor, with matched resistances from both sides of the monitor connected back to positive and negative inputs to the transducer, and a control voltage applied across the inputs.

摘要： On programme un appareil automatisé (11) de sorte qu'il effectue un procédé, en disposant une séquence de premiers pictogrammes (69) sur un écran (15) dans l'ordre du procédé. Les premiers pictogrammes (69) représentent les fonctions de l'appareil (11) et au moins un parmi eux est une représentation visuelle d'une fonction de l'appareil (11). Au moins un de ces premiers pictogrammes peut être agrandi afin qu'il présente des deuxièmes pictogrammes (81) qui constituent la fonction d'au moins l'un desdits premiers pictogrammes (69), et au moins un des deuxièmes pictogrammes (81) est une représentation visuelle d'une sous-fonction de l'appareil (11). Dans un mode de réalisation préféré, lorsqu'au moins un des premiers pictogrammes (69) est agrandi, il garde, par rapport à l'autre des premiers pictogrammes (69) de la séquence, la même position séquentielle qu'il avait à l'écran (15) avant d'être agrandi.

摘要： A gas cap (16) for a thermal spray gun (10) has a passage therethrough including an entrance channel (128), an exit channel (132), and an intermediate channel (130) connecting between the entrance and exit channels (128,132). The entrance channel (128) is cylindrical on an entrance axis, and the exit channel (132) is convergingly conical on an exit axis oriented at 45 o to the entrance axis. The intermediate channel (130) is symmetrical to the plane of the entrance and exit axes and has a near portion and a far portion. The near portion is semicylindrical about the entrance axis, and the far portion is semicylindrical about a far axis segment lying in the plane. That segment is offset from the entrance axis away from the exit end of the gas cap, and is oriented at 14 o to the entrance axis, the three axes intersecting at a common point.

摘要： Liquid chromatography column coupling assembly having a column enclosed in a housing member to form a column cartridge and including coupling assemblies at respective ends of the cartridge, each comprising a coupler member and a collar member. The coupler member and collar member are tubular in configuration and disposed in coaxial telescoping relation with one end of the coupler member abutting the respective end of the column with an annular seal interposed therebetween. The collar member has one end threaded onto the end of the column housing and at its opposite end an inwardly extending radial flange coacting with an outwardly extending radial flange on said one end of the coupling member. Rotation of the collar member when threading it onto the column housing causes relative axial displacement of the member to compress the seal between the abutting ends of the column and coupler member.

摘要： A thermal spray gun includes a first burner (40) for producing a first fan-shaped flame, a second burner (40') for producing a second fa-shaped flame parallel to the first in sufficient proximity to commingle into a combined fan-shaped flame. Powder is dispersed into a fan-shaped powder spray entrained between the first and second flames. The gun body has a fan-shaped powder chamber with an open side opening forwardly from the gun body between the first flame and the second flame and with an apex lcoation opposite the open side. First and second powder ducts each terminate at the apex location with a common axis perpendicular to the fan-shaped chamber such as to mutually impinge the first and second powder streams into a combined powder stream dispersing through the fan-shaped powder chamber into the fan-shaped powder spray. A first fan-shaped air flow is introduced between the first flame and the fan-shaped air flow is introduced between the first flame and the fan-shaped powder spray, and a second fan-shaped air flow is introduced between the second flame and the fan-shaped powder spray.

摘要： A method and system for polynucleotide synthesis and purification are provided which employ solid phase synthesis on a nonswellable porous polystyrene support by phosphoramidite or hydrogen phosphonate chemistries. The polystyrene support gives rise to fewer tritylated failure sequences caused by chain growth from extraneous support sites. Consequently, crrently used rapid purification techniques depending on trityl hydrophobicity give a more highly purified product. The method and system also employ nucleoside intermediates whose exocyclic amines are protected by base-labile groups which permit simultaneous cleavage and deprotection of the completed polynucleotide chain in the presence of the solid phase support. This latter feature allows practical automation of both the synthesis and purification of polynucleotides.
