Abstract: ABSTRACT OF THE DISCLOSURE           A flexible surveyor's marker for use in place of the usual rigid surveyor's stake is disclosed which includes an elongated strip of stiff, yet flexible, foldable material such as a suitable plastic.  The strip includes an elongated body portion and a pair of tabs connected to one end of the body portion along a fold line.          The body portion contains a crease disposed lengthwise thereon along a longitudinally extending centerline to enable the tabs to overlap one another.  Holes formed through the center of each of the tabs can be aligned in registry with one another as the tabs are slid into position overlapping one another to allow a nail to be inserted therethrough for insertion into the ground. The tabs may contain sev-eral holes of differing diameter to accommodate nails, spikes or tacks of differing diameters.  The crease also allows the body portion to tilt out of a plane containing the tabs toward a position extending perpendicular to a plane containing or parallel to the tabs as the tabs are moved by hand across one another to a position wherein the tab holes register with one another.  The body portion of the strip may contain suitable longitudinally extending graduations and a slit may be formed in an upper end portion of the body portion to allow a cloth flag to be inserted therein.  A series of graduations extending laterally from either side of the centerline along an upper edge portion of the body portion may be provided to enable a survey instru-ment operator to locate the centerline when, due to his line of sight with respect to the body portion, the centerline is not viewable, and also to aid a surveyor in establishing a precise straight line between successive markers by the double centering technique.  A transverse tear line, which may be in the form of perforations, is provided on a lower end portion of the strip above the fold line to allow an upper portion of the marker to be torn away without dislodging the nail from the ground when the marker is struck by a wheel or tread of a vehicle or a mower blade.                                -1a-

Abstract: ABSTRACT      A constant current battery charging circuit is pro-vided by which the battery receives a full charge until the battery voltage reaches a threshold.  When the battery voltage is above the threshold, the battery receives a trickle charge.  The actual battery voltage is compared with a reference voltage to determine whether the full charge circuit should be in operation.  Hysteresis is pro-vided for preventing a rapid on/off operation around the threshold.  The reference voltage is compensated for temperature variations.  The hysteresis system and temper-ature compensation system are independent of each other. A separate test circuit is provided for testing the battery voltage.  During testing of the battery, the full charge circuit is inoperative.
