Abstract: A guidance technique for producing a relief sculpture in which clay material is disposed between two parallel elevating tracks and is flattened by a cylindrical member supported by the tracks to form a design blank of a predetermined thickness. A design element template is used to direct the carving of a design element from the design blank. A plurality of design elements are successively formed accordingly. The thickness of each design element is determined by varying the number of flat track members that are stacked to form the parallel elevating tracks. The design elements are mounted on a base member to form a semi-finished intermediate, which is thereafter dried and baked to yield a finished relief sculpture.

Abstract: An apparatus for cleaning a measuring tape, used for measuring the depth of oil in a storage tank and partially immersed in the oil for this purpose, is mounted in the tank beneath a hatch in the top of the tank. The tape is cleaned by drawing it through a cut in a rubber plate which is supported on three sides and partially on a fourth side by a metal plate used to mount the apparatus on the tank. The cut communicates with the fourth side of the rubber plate so that the metal plate positions the sides of the cut while permitting the tape to be inserted into the cut at any position along the length of the tape.

Abstract: An improved print roller for applying dye to a textile material in a predetermined pattern is provided wherein the core of the roller, which is operatively supported in a rotatable position by a shaft, is encapsulated with a cover formed of a substantially impervious elastomeric material. Dye applicators are then bonded to the cover.

Abstract: A socket heat fusion apparatus is provided for simultaneously heating one end portion of a thermoplastic conduit and one end portion of a thermoplastic coupler so that the heated end portion of the thermoplastic conduit can be disposed in the heated end portion of the thermoplastic coupler to provide a substantially fluid-tight union therebetween. The apparatus comprises a body member having a first heat communication opening and a second heat communication opening, the second heat communication opening extending through the body member and openly communicating with the first heat communication opening; a first receptacle disposed on one side of the body member for receiving one end portion of the thermoplastic conduit, the first receptacle communicating with the second heat communication opening; and, a second receptacle disposed on a second side of the body member for receiving one end portion of a thermoplastic coupler, the second receptacle openly communicating with the second heat communication opening.

Abstract: The present invention contemplates an improved material moving apparatus which is particularly useful for blowing insulation material into portions of various structures. The apparatus includes: a hopper, having a chamber; a hopper blade assembly; a blower assembly; and a discharge conduit. The material is discharged into the hopper chamber, contacted by the hopper blade assembly, and moved through the blower assembly into the discharge conduit for discharging the material from the material moving apparatus.

Abstract: An improved ventilator apparatus for venting objectionable odors from a structure, while, at the same time, circulating fresh air through the structure, the ventilator apparatus comprising a vent conduit secured to the structure such that one end portion of the vent conduit is disposed within a lower interior portion of the structure and the opposite end portion extends from the structure and thus establishes fluid communication between the lower interior portion of the structure and the atmosphere, a housing encompassing a portion of the vent conduit, one end portion of the housing being disposed within the structure, the housing having two passageways therein for establishing fluid communication through the housing between an upper interior portion of the structure and the atmosphere, a terminal housing having an inlet and outlet, the terminal housing being rotatably mounted on the vent conduit and the housing such that the inlet of the terminal housing communicates with one of the passageways in the housin

Abstract: A reversible push block-rear bumper assembly for attachment to a motor vehicle is provided in which a support unit having a forwardly inclined downwardly extending surface is secured to the underside of a vehicle in close proximity to the rear end of the vehicle. A block unit having an upper incline surface which can be mated with the forwardly incline downwardly extending surface of the support unit is also provided, such surfaces being adapted so that when the block unit and support unit are secured together, the block unit will either extend downwardly from the support unit in a plane substantially perpendicular to the longitudinal plane of the vehicle and thus function as a bumper or, upon rotating the block unit 180.degree. into a reverse position, the block unit will extend outwardly from the rear end portion of the vehicle for use as a push block.

Abstract: A wheeled roadway planing machine in which the wheels are pivotable by individual hydraulic rams for steering purposes. Each ram is controlled by a rotary, blocked-center valve and the valves are simulataneously actuated by a linkage which establishes a pattern of off-center displacements of their valve members to initiate pivoting of the wheels. The valves are mounted on pivotable wheel representation members which pivot with the wheels, via cables connecting the representation members to support shafts upon which the wheels are mounted, to return the valves to their blocked-center positions as the wheels pivot to a pattern of positions on the chassis of the machine similar to the pattern of displacements of the valve members resulting from operation of the linkage. A cutting drum is mounted on the chassis to form a cut in the roadway, such cut having a shape determined by the position of the chassis on the support shafts.
