Abstract: ABSTRACT     A device for measuring the oil or fluid level in engine sumps or other containers is known to consist of a removable dipstick marked with a scale and equipped with an extraction handle, riding freely longitudinally in a tube leading to the outside, so that the oil or fluid level may be read on the scale when the dipstick is extracted.   In this invention, the dipstick is self-retracting, being the outer end of a coil spring of suitable length and tension, its outer end straightened for a suitable length, marked with a scale, led outside through the tube, and equipped with a handle which may be detachable for disassembly, the inner end of the coil secured to an arbor, such arbor immobilized between guide plates or discs, the spring being free to tighten around the arbor when the straight portion is extracted, but exerting sufficient tension to expand and retract the straight portion when the extractive tension is removed.   Alternatively, the measuring part may be a measuring blade of suitable dimensions linked for flexibility to the outer end of such coil spring, or the straight portion may be reinforced with a metal strip along its length.   The straight portion or measuring blade passes freely through the tube between two wiping pads of felt or other suitable material, one fixed, the other movable by external pressure through an aperture in the tube, pressure being applied to the movable pad when required to compress the straight portion or blade against the fixed pad to clean it of oil or fluid while it is being extracted, a light spring returning the movable pad to its original position when the external pressure is removed, with sufficient clearance so that the straight part or blade will not again be wiped when retracted and re-extracted to show on the scale the oil or fluid level inside the sump or container.

Abstract: ABSTRACT OF THE DISCLOSURE           A heat exchanger for refrigerator evaporators of the type consisting of helically coiled refrigerant-carrying tubing with radially inward extending fins formed along the length of the coiled tubing, with the air to be refrigerated directed across the axis of the coil turns.  The coil turns are skewed from the helix angle to  expose a greater propor-tion of the fins into the air flow path between the coil turns so as to increase the air flow contact with the fins.  The skewing is created by relatively offsetting opposite portions of the coil turns along the air flow path across the helical coil to increase the obliqueness of a portion of each coil turn with respect to the direction of air flow.  The tube coil includes sections folded into a side-by-side relationship, with the skew direction of the coil sections placed in reverse orientations to increase the length of the flow path of the air circulated through the coils and to position gaps between each of the coil turns in either section opposite the areas in the other coil section occupied by radial fins.

Abstract: TO ALL WHOM IT MAY CONCERN:                 Be it known that I, BRONISLAW SEEMAN, have invented an improvement in APPARATUS AND METHOD FOR DETERMINING VELOCITY               OF ACOUSTIC WAVES IN EARTH FORMATIONS     of which the following is a SPECIFICATION     ABSTRACT OF THE DISCLOSURE     The disclosure is directed to an apparatus and method for determining the velocity of acoustic wave energy propagating information surrounding a borehole.  In accordance with one form of the apparatus, a transmitter is positioned in the borehole and periodically establishes acoustic wave energy in the surrounding formations.  The acoustic wave energy is received at a plurality of spaced locations in the borehole and a plurality of signals are derived which are respectively representative of the wave energy received at the plurality of spaced locations in the borehole.          Means are provided, for correlating a first portion of the signal from one of the receiver locations with first portions of signals from the other receiver locations.  The time references of the first portion of the signals from the other locations are determined from an assumed velocity in conjunction with the time reference of the first portion of the signal from the one receiver location and the distance to each of the other receivers.  The correlating is performed for a number of different assumed velocities to obtain a resultant first provisional velocity.  In particular, the assumed velocity which yields substantially the maximum or best correlation is selected as the first provisional velocity.  Means are also provided for correlating a second portion of the signal from said one of the receiver locations with second portions of the signals from the other receiver locations.  Again, the second portions of the signals from the other receiver locations are determined using an assumed velocity, and the correlating of second portions is performed for a number of different assumed velocities to obtain a resultant second provisional velocity.  An output velocity is then generated as a function of the first, second, and other similarly generated velocities.  An output velocity for the compressional component of the acoustic wave energy and/or an output velocity for the shear component of the acoustic wave energy can be obtained using the disclosed technique.
