Abstract: Methods and apparatus for evaluating a formation include conveying a formation evaluation tool in a borehole on a tubular carrier extending from a surface location at least to the formation evaluation tool. A cable is conveyed to the formation evaluation tool and communication between the formation evaluation tool and the cable is established after the formation evaluation tool is moved to a selected borehole location.

Abstract: An electronic programmer for the auto-dial functions of a telephone comprises an apparatus which electrically connects the rows and columns lines on the keyboard of a telephone so as to mimic the pressing the buttons on the telephone keypad.

Abstract: A method and apparatus for assembling a multi-panel door. The method includes the steps of fashioning a plurality of rails; fashioning a plurality of panels; fashioning a plurality of mullions; fashioning a plurality of stiles; and preassembling selected rails, selected panels, and selected mullions into sub-assemblies of the door. The sub-assemblies are positioned intermediate a first stile and a second stile in a pre-assembly orientation with the first stile and second stile generally coplanar with the sub-assemblies. The sub-assemblies, the first stile, and the second stile are compressively urged together in two substantially perpendicular axes to create a squared assembly with respect to the two axes. The sub-assemblies are intermediate the first stile and the second stile and are affixed to the first stile along at least a portion of the first stile, and are affixed to the second stile along at least a portion of the second stile.

Abstract: A closure, such as a door or window unit, and a joint for such a closure are provided. The closure has an inside and an outside, and includes a plurality of first frame members alternately joined to a plurality of second frame members to form a planar frame, and a panel member is positioned within the frame. The joint, formed at each location where a first frame member abuts a second frame member, includes an end area of a first frame member, a mating area of a second frame member and a sealing member. The sealing member is disposed at the interface defined between the end area and the mating area to establish a weather-resistant barrier between the inside and the outside of the closure. A method for fabricating a closure is also provided.

Abstract: A frequency agile homodyne full duplex FSK system having a receiver section using an image-cancellation mixer wherein sum and difference signals generated by a pair of double-balanced mixers are added together with proper phase to cancel out the image response normally associated with heterodyne receivers and directly down-convert the carrier frequency to the baseband frequency. The transmitter section of the FSK system consists of an FSK modulator whose peak deviation is controlled by an active derivative of a crystal clock. The FSK modulator functions in the manner of a phasing single sideband (SSB) mixer with upper or lower sideband signals generated by the proper phasing of quadrature components of the carrier frequency and the peak deviation signal derived from a crystal clock.

Abstract: An adaptive power amplifier system for use with VSWR loads includes an adaptive power supply that indirectly monitors the power dissipated by a RF power amplifier and adapts bias conditions of solid state components in the RF power amplifier to protect the components from excessive power dissipation typically experienced with VSWR loads, even while maintaining full forward power output.

Abstract: Molten steel containing an undissolved alloying ingredient denser than molten steel (e.g. Pb and/or Bi) flows from a tundish to a continuous casting mold. Various expedients are employed to prevent large globules of undissolved alloying ingredient from flowing out of the tundish into the mold. Another expedient prevents large quantities of undissolved alloying ingredient from accumulating on the bottom of the tundish.

Abstract: An elongated, vertical conduit has an upper end, communicating with the bottom opening in an upper container or ladle, and an open lower end disposed above the top surface of a bath of molten metal in a lower container or tundish. A descending stream of molten metal is directed from the conduit into the bath. A shroud encloses the conduit and the descending stream. The pressure within the shroud is lower than the outside pressure and is regulated. A mixture of transport gas and solid, particulate alloying ingredient prone to excessive fuming is injected into the descending stream within the shroud.

Abstract: A non-linear phase detector is disclosed which compensates for gains occuring during tuning a frequency generator of a known phase locked loop circuit which incorporates a Varactor tuned resonant circuit as a VCO. The phase detector is of the sample and hold type and incorporates a Varactor rather than a hold capacator to compensate for non-linear gains which occur when tuning the frequency generator across its band spread. Additionally, bias compensation is provided for the resonant circuit Varactor to offset its contact potential.

Abstract: A frequency agile phase detector includes a digital frequency detector section connected to a hold-sample-hold phase detector section. The digital frequency detector develops control signals related to frequency differences between a reference periodic signal and a variable periodic signal. The control signal determines the amplitude of a voltage signal impressed across a first hold circuit. A sample signal acts to sample and transfer the sample voltage signal from the first to a second hold circuit so as to reduce phase differences between the reference and variable periodic signals. The detector is incorporated into a phase locked loop using the VCO output as the variable periodic signal so that acquisition and lockup of the loop is obtained even when the two periodic signals are decades apart. Additionally, the hold-sample-hold section aids in reducing the reference and sampling energy required which results in a spectrally pure output signal.
