Abstract: ABSTRACT OF THE DISCLOSURE            A method and apparatus are disclosed for use in forming words on tape, useful e.g. as labels, from sheets bearing printed, transferable characters, e.g a set of printed alphabets.      A tape dispenser containing a roll of a transparent adhesive tape includes a frame defining a rectangular window which can be positioned horizontally and vertically at any place over the character sheet. When it is desired to transfer a selected letter to the tape, the user presses the selected area of the tape against the letter   Because of the tacky adhesive on the tape, when pressure is removed, the selected letter is lifted from the indicia sheet and transferred to the tape.  The process is repeated as often as necessary to form the desired word.  The strip on which the word has been formed is then severed from the roll and adhered to any desired receiving surface by means of the tacky adhesive on the tape.      Accurate base-line adjustment of the characters forming the word is provided by means of an indexing mechanism which enables the tape dispensing to move vertically within a slide to fixed positions exactly correlating to the rows of printed characters on the sheet.                                    .

Abstract: ABSTRACT The invention relates to a mechanical press and in particular to a means fox achieving thermal  stability, particularly shutheight stability, by utilizing the waste heat from lubricant circulated through the drive assembly (46) to heat the uprights (18). The oil is circulated through the crankshaft and connection arm assembly in the crown (20) and then caused to flow through a thermal transfer device (296) mounted to each of the uprights wherein the heated oil stransfers a portion of its heat to the uprights so that they elongate due to thermal expansion at the same rate as the connection arms (142).  The thermal transfer devices comprise a plurality of baffles (298) over and through which the oil flows under gravity or pres-sure, wherein the baffles cause the oil to form a plural-ity of vertically spaced pools in good thermal contact with the uprights.   By adjusting the baffle structure so that the oil flows downwardly at a higher or lower rate, the amount of thermal transfer can be adjusted to ensure that equal thermal growth of the uprights and connections occurs.

Abstract: ABSTRACT OF THE DISCLOSURE         A method for controlling the flow of drilling fluid through a subaqueous wellbore is disclosed.  The method comprises the steps of continuously measuring the output flow rate (A) of the drilling fluid from the wellbore, the input flow rate (B) of the drilling fluid to the wellbore, and at least a component of the pitch and roll (P/R) of the vessel, computating a floating alarm limit (C) dependent upon the pitch and roll (P/R) signal and the roughness of the sea, filtering the periodic fluctuation of the output flow rate (A) due to the motion of the vessel, and computating the delta flow signal (D) by subtracting the input flow rate (B) from the filtered output flow rate (A).  The method further comprises the step of generating a signal whenever the absolute value of the delta flow rate (D) exceeds the floating alarm limit (C) to provide a visible warning that the flow of drilling fluid is out of control and to either close off the wellbore in case of a kick or to stop the flow of fluid and stop drilling in case of lost returns.       Apparatus for controlling the flow of drilling fluid through a subaqueous wellbore is disclosed while drilling from a floating vessel.         The wellbore is connected to the lower end of the drill string and the lower end of an annulus by a valve through which the drilling fluid flows.  The upper end of the annulus is connected to a conduit from which the drilling flows to the suction side of a pump which circulates the drilling fluid therefrom into the upper end of the drill string, through the wellbore, and back up the annulus into the conduit.  The apparation comprises an output flow meter connected to the exit of the conduit, an input flow meter connected between the pump and the upper end of the drill string, means mounted on the vessel for sensing the pitch and roll of the vessel, and computer means for receiving the output flow rate (A) signal from the output flow meter, the input flow rate (B) from the input flow meter, and the pitch and roll (P/R) signal from the pitch and roll sensing means.  The computer means calculates an alarm limit (C) based on the pitch and roll (P/R) signal and the roughness of the sea continuously filters the periodic fluctuation of the output flow rate (A) due to the motion of the vessel, computes the delta flow signal (D) by subtracting the input flow rate (B) from the filtered output flow rate (A), and generates a signal whenever the delta flow rate (D) exceeds the floating alarm limit (C) to provide a warning of a possible blowout or lost circulation condition and to either close off the wellbore in case of a kick or to stop the flow of fluid and stop drilling in case of lost returns.

Abstract: ABSTRACT An apparatus and method for verifying the accuracy of watt-hour meters at their operational site includes applying a phantom load to the meter and to a watt transducer.  The relative watt hour readings of the meter are compared to the watt hours computed from the power to the watt transducer and represented as a percentage error of the meter.  The phantom load is constituted by a loading transformer with optional load adjustments to take into account different loads to the meter and there are also adjustment means to take into consideration different meter characteristics.  The meter watt hour reading is determined from an articulated light generating and receiving means mounted in alignment with the revolving disc so that light passes through the aperture in the disc to the receiving means and then signals the verifying apparatus to give an indication of the watt hour reading of the meter.  Alternatively the reading is obtained manually.
