Abstract: Disclosed are mixed alkyl cyanoacrylate compositions which are specifically formulated for topical application onto intact or broken human skin, preferably without the addition of a plasticizing agent to the composition.

Abstract: Invented are stabilized tablet formulations of substituted 3,5-diene steroidal compounds. Also invented are methods of preparing stabilized tablet formulations of substituted 3,5-diene steroidal compounds.

Abstract: Protocol converter device converts between a 4-20 mA analog signal format and a digital Fieldbus signal format. An input circuit is provided, coupled to the transmitters which includes a multiplexer for selecting one of the analog signals from the transmitters of, e.g., three different field devices or from the analog signal converted from a digital signal. After the analog signal is converted to a digital signal, a central processing unit converts the converted digital signal into a digital quantity of a property of interest which may be display and/or transmitted to other devices or a control computer via a Fieldbus. The central processing unit selects which transmitter converted analog signal is to be displayed. The converter circuit can be placed in an environmental hazard resistant housing, to create a protocol conversion unit that can be located in a convenient field or control center location.

Abstract: A process and apparatus are provided to enhance the recovery of petroleum from onshore and offshore reservoirs. The process includes the simultaneous stimulation of the formation by elastic sound waves, created by a sonic source installed at the oil well so that the elastic sonic waves which are superimposed reduce the adherence forces in the layer between oil/water and the rock formation, and by the oscillating electrical stimulation of the same layer, as from the same wells subject to sonic treatment. The electricity heats the formation by using resistive heating, and thus increases the pressure, thus eliminating the surface tensions between the faces of the fluid as a consequence of the oscillatory action of the ions in the surfaces of the fluid and in addition, reducing the viscosity of the fluids.

Abstract: A tractor includes a seat swivelly mounted on a single seat support arm or member that is vertically swingably mounted on the chassis of the tractor for movement about a horizontal transverse axis between a generally horizontal forward position for disposing the seat in a forwardly facing position for tractor operation and a generally vertical rearward position for disposing the seat in a rearwardly facing position for backhoe operation. The axis about which the seat may swivel is related to the angular displacement of the arm from its forward to its rearward position such that when the arm is repositioned the seat may be repositioned by rotating it through 180.degree.. Latch members are provided for releasably retaining the arm and the seat in selected positions and a single control arm is connected to the latch members so as to simultaneously unlock the arm and the seat when it is desired to reposition the arm and the seat.
