Abstract: An improved adjustable assembly for supporting a monitor or the like under a transparent window portion of a desk top member or like structure. The assembly incorporates a shelf member which is supported at each lateral end thereof by a side support. The shelf member is preferably so supported by a locking block arrangement for each of a total of four supporting shaft members that outwardly extend from the shelf member. The position of the shelf member in relation to the side support is adjustable for height and tilting purposes. The shelf member and the side supports are formed of wire.

Abstract: A controlled release device for the administration of biologically active growth hormone proteins or peptide fragments, and method of preparation thereof, wherein biologically active growth hormone is stabilized and release rate modulated by incorporation of a stabilizing compound. The controlled release devices are prepared by mixing a stabilizer, such as sucrose, with a biologically active growth hormone, such as bovine somatotropic hormone, in solution, lyophilizing, then incorporating the dried powder into a surface erodible, biocompatible polymeric matrix, such as a poly(anhydride) or poly(orthoester) matrix.

Abstract: An insulating support for a helical wire heating coil for an electric resistance heating element includes a coil supporting notch into which a single helical coil turn is inserted and locked into position without twisting the coil and without unduly stretching the coil in an axial direction. The supporting notch includes lead-in ramp surfaces to spread the two halves of the coil turn until the coil is centrally positioned in the notch, whereupon the coil turn snaps into locking engagement with four separate abutments to prevent dislodgement. A central portion in the notch includes a separate coil supporting surface that limits further movement of the coil into the notch and the notch also includes interior lateral abutment surfaces to engage the outside of the coil turn and prevent lateral movement in the notch. The faces of the support body adjacent the notch are engaged by opposite half portions of the coil turn to preclude axial movement of the coil once it is locked in position.

Abstract: An apparatus for correcting an initial measurement of the concentration of a first water soluble species dissolved in a water-based component of a biological fluid that also includes a second water soluble species and a volume occupying component, the initial measurement having been taken using an original sample of the fluid that had been diluted by an amount of additional aqueous solution to form a diluted sample is disclosed; the concentration of the second water soluble species is measured in an undiluted sample of the biological fluid to obtain a direct concentration and is measured using a diluted sample of the fluid to obtain an indirect concentration, and the initial measurement of concentration of the first species is adjusted based on a combination of the direct and indirect concentration determination of the second species.

Abstract: A rotary electrical machine comprises a rotor assembly and a stator assembly separated by an air gap. The stator is formed from discrete generally pie-shaped pole pieces having a progressively increasing radial slot to accommodate winding of the coil. The pole pieces are preferably wound from a grain oriented ferromagnetic tape to improve the permeability of the pole and its saturation level. Groups of poles may be separated into sectors. In an alternative embodiment, at least some of the pole pieces are formed from both a permanent magnet and ferromagnetic tape to provide a constant bias between the rotor and stator assemblies.

Abstract: The present invention relates to an apparatus and process for estimating the pour point of a hydrocarbon oil. The pour point of hydrocarbon oil gives an indication of its low temperature properties, and is determined according to the time-consuming procedures set out in the American Society of Testing and Materials (ASTM) test D-97. The present invention generally provides a convenient means to estimate the pour point of a hydrocarbon oil, by directing a flow of pressurized gas towards a sample of the oil, and determining the warmest temperature at which the gas flow does not cause a substantial surface wave on the oil surface.

Abstract: Apparatus for monitoring the cloud point of a liquid, or the temperature at which any light scattering phase occurs therein, comprising a light-proof and light-absorbing chamber, and a liquid sample-receiving receptacle within the chamber having a bottom formed by a non-light-scattering surface; this surface being in thermal contact with a heating or cooling device, such as a thermoelectric cooler, and with a temperature measurement device. The chamber can be opened to allow access to the receptacle so that sample liquid can be placed therein. A light beam source is located to direct a beam of light onto the surface at an incident angle so that light from the beam is reflected or absorbed by the surface. A light detector including a lens and an array of detection cells is arranged so as to detect scattered light which is produced when solid material forms in the liquid as it is cooled or disappears on heating.

Abstract: An axial magnetic bearing includes a rotor overlying a coil in a stator. A second coil is disposed at a location where it does not exert a significant force on the rotor. The second coil generates a magnetic field to oppose and substantially cancel the stray magnetic field generated by the first coil.

Abstract: A piston for an internal combustion engine is described, the piston having a lower crown portion and an upper crown portion, the upper crown portion including a combustion bowl and a piston ring-groove belt of generally annular form depending from the outer periphery of the crown surface, the lower crown portion comprising a generally circular plate member having an upstanding ring on the upper surface thereof, the upper crown portion and the lower crown portion being joined together by retention means between the combustion bowl and the upstanding ring, and between co-operating spigot and socket means formed on the base of the combustion bowl and on the plate member, to prevent withdrawal by axial forces, and there being an oil cooling gallery defined between the upper crown portion and the lower crown portion.

Abstract: A switch for an inductive load includes a first leg having a first field effect transistor connected between one terminal of the load to the high potential terminal of a power supply and a second leg having a second field effect transistor connected between the other terminal of the load and the low potential terminal of the power supply. A plurality of current paths located on opposite sides of the load terminals connected in parallel and extend from one of the load terminals to one of the power supply terminals. Each current path includes an inductor connected in series with a diode. A choke energy path is associated with each current path and includes a diode connected in series with a resistors. The inductors in the current paths operate to inhibit reverse recovery current through the diodes while the choke energy paths dissipate oscillation energy in the switch upon operation of the transistors to connect the inductive load across the terminals of the power supply.

Abstract: A bearing bushing incorporating a sleeve (1) of magnetizable material forming the sliding surface of the bearing, a shaft (2) mounted in said sleeve (1) and a lubricant in the form of a magnetic fluid (3) between the sliding surface of the sleeve (1) and the shaft (2), whereby the sleeve (1) is magnetized in axial direction. For causing a hydrodynamic lubrication and an increased cooling effect the sleeve (1) on the inner side has axial channels (7) and axial recesses (9) on the outer side thus that the magnetic fluid (3) by the axial magnetic field around the sleeve (1), can be given a circulating motion along the inner and outer side of the sleeve.

Abstract: In a screw and nut driving device with low internal friction, e.g. a ball nut mechanism, irreversibility is effected in a simple and efficient manner when the nut is rotatably driven and enclosed by an annular space in which a helical spring is arranged in such a manner that its ends are acted upon by the driving force from the external driving source, thus that the spring can rotate freely in the space. When the external driving source is disconnected and the nut, due to axial load is subjected to a torque, the ends of the spring are acted upon thus that the spring is deformed to friction locking against a non-rotating surface, whereby the nut is prevented from rotation.
