Abstract: An indicator plate is provided which is embedded in the ground adjacent an inlet to a storage tank. The indicator plate is formed from materials which can support vehicular traffic directly thereupon without degradation of indicia located upon a top surface of the indicator plate. The indicator plate is formed from two separate molds. A first mold forms indicators. These indicators are then placed within a second mold which is then filled with fluid material in a manner which allows the indicators to be exposed through a top surface of the plate after the material hardens. A bolt is also placed within the material before hardening for anchoring the plate to the ground adjacent the inlet to the storage tank.

Abstract: A pointer for measuring instruments includes a fixing portion mounted on a drive shaft of a drive and an indicating portion supported on the fixing portion and extending therefrom in a direction perpendicular to an axis of the drive shaft. The indicating portion includes an EL element having a light-emitting surface extending over a substantially entire length of the indicating portion in the direction perpendicular to the drive shaft axis, at the light-emitting surface light being substantially uniformly distributed at least in the direction perpendicular to the drive shaft axis; a light-transmitting protective body covering at least the light-emitting surface; and an indicating tube. The surface of the portion of the indicating tube confronting at least the above light-emitting surface is arcuated in a circumferential direction of the direction perpendicular to the drive shaft axis.

Abstract: A level controller including a base plate having an upright support, a platform supported on and turned about the upright support, a status detector mounted on the bottom side of the platform to detect the position of the platform through an X-axis detector unit and a Y-axis detector unit and to provide an output signal corresponding to the result of the detection, a X-axis motor and a Y-axis motor arranged on the base plate at right angles, and a microprocessor controlled by the X-axis detector unit and Y-axis detector unit of the status detector to turn the X-axis motor and the Y-axis motor in keeping the platform on an even horizontal plane.

Abstract: A storable diver's flag which is visible in substantially all directions. The flag includes three flexible rectangular panels connected to one another along a common central pocket formed between the panels. The panels are thus vertically automatically radially extendible to an in-use position generally radially equal angles between adjacent panels whereby diver down indicia on both surfaces of the panels allow the upright in-use flag and indicia to be seen from any direction. A support member having an elongated mast and three support arms radially extending from near each end of the mast extend along each radial margin of each panel to maintain the panels in an extended and upstanding in use position. The support member is preferably embedded and adhered in place between each pair of sheet material portions themselves adhered together to form each flag panel.

Abstract: A preferred embodiment of the invention includes a passive type marker device (10) with a stem (11) placed in contact with or adjacent to a hidden object (14) or other particular point, providing for visual and/or electronic identification of such. Measurements (20) and directional markings (24) imprinted along the stem face indicate distance to the object. An alignment saddle (12) astride the object self aligns an arrow opening (18) through the stem defines the object's orientation relative to its surroundings. The device's color indicates object type such as red for electric, blue for water, etc. A marker dial (46) for optional placement in a finished surface also defines the object depth. The dial is indexedly installed atop an alignment indicating adapter (44) which is self aligned by insertion into the arrow opening of the stem. An arrow and indicia atop the adapter indicates the orientation and size of the object.

Abstract: An identification device for mounting on the antenna of a transport vehicle. The device is tubular and resilient, and has a central cavity for receiving the antenna. A series of spaced apart external grooves selectively accept a tie constricting the tubular device about the antenna. The device has hook and loop material attached thereto, and a corresponding patch of hook and loop material. The corresponding patch is mounted to the vehicle, for temporary stowage of the identification device when not in use. The identification device has one or more distinctive bright colors, for being conspicuous at a distance. The device is preferably employed when parking a vehicle amidst many similar vehicles, thereby enabling an owner or operator to identify the vehicle.

Abstract: A fixture for elevated utility lines, deployable from a hoverable vehicle having a load attachment point, each fixture having a body with a slot formed therein for receiving the line; a trap having one or a pair of movable arms for holding the line within the slot; a cocking mechanism for holding the trap in an open condition; and a trigger mechanism activated by contact with the line for releasing the cocking mechanism, and a trap releaser including a supportive hook receiver for releasing the trap during removal of the body from the line. A system for deploying fixtures also includes a base, an attachment for releasably suspending the base from the load attachment point and having a stabilizer bar supportively connected relative to the attachment point and resiliently oriented relative to the vehicle, a yoke releasably supported relative to the load attachment point, the base being suspended from the yoke.
