Abstract: An acoustic panel for a gas turbine engine, includes a panel body, a panel-body cover, and a support bracket. The panel body is configured to dampen vibrations caused by the gas turbine engine. The forward support bracket is configured to mount the acoustic panel to portions of the gas turbine engine.

Abstract: This unique and novel invention provides a telescoping level device used to effectively and efficiently measure the slope of objects and surfaces. The device comprises a telescoping arm, a ball joint, a level, and one or more contactors. The device allows the user to easily, accurately, and quickly verify the in-situ slope of pipes as well as a plurality of other objects and surfaces. The length and angle of the telescoping arm, relative to the level, are adjustable to prevent the user from unnecessarily stooping, kneeling, or climbing.

Abstract: A cutting machine includes a gun barrel for receiving a projectile. A compression tube is disposed in flow communication with the barrel and includes a piston therein. A reservoir is disposed in flow communication with the tube and receives a first gas under pressure. A second gas fills the compression tube on a front face of the piston. And, the pressurized first gas is discharged into the tube on a back face of the piston to accelerate the piston through the tube for compressing the second gas, and in turn launching the projectile through the barrel to impact a workpiece.

Abstract: An apparatus for applying polymer to metal pipe during the pipe forming process has a pump for pumping the polymer, a first extruder die receiving polymer from the pump and configured to apply polymer to metal pipe as the metal pipe is being formed from metal stock, and a second extruder die for forming pipe couplers. A valve effects diversion of the polymer from the first extruder die to the second extruder die when a stoppage of the pipe forming process occurs.

Abstract: Improved turbine comprising plural turbine blades supported by a turbine rotor of a flow meter, each turbine blade having a rounded leading edge, a feathered trailing edge, a concave top blade surface and a convex bottom blade surface, the turbine blade tapered from the leading edge to the trailing edge to form a hydrofoil shaped defined by empirical profile data.

Abstract: A resistance heater heats air forced by a fan into a woodstove secondary combustion chamber having an ignitor. The fan, heater and ignitor are controlled by a temperature sensor for gas flowing from a primary combustion chamber to a secondary combustion chamber. Two ignitors, extending through the stove back wall into the secondary combustion chamber, are controlled by the temperature sensor.

Abstract: Improved turbine comprising plural turbine blades supported by a turbine rotor of a flow meter, each turbine blade having a rounded leading edge, a feathered trailing edge, a convave top blade surface and a convex bottom blade surface, the turbine blade tapered from the leading edge to the trailing edge to form a hydrofoil shape defined by empirical profile date.

Abstract: A flow meter mounted in a flow delivery line and having a meter housing with a fluid opening and an electric counter. A turbine rotor supported on a turbine shaft is disposed in the fluid opening, the turbine having plural turbine blades with ferrous slugs embedded therein, the electric counter responding thereto for fluid delivery indication. Each turbine blade is tapered from front to rear into a feathered trailing edge and has a top concave surface along its length and a bottom convex surface. A pair of shaft supports, having fluid ports for washing about the turbine shaft, are provided to support the turbine rotor.

Abstract: A method and apparatus for reducing unnecessary elevator service calls by cycling open and shut a nonresponsive car's door, is disclosed. The doors are cycled in the presence of car demand and indications the car door is shut but the hoistway door is ajar. The doors are cycled only after these conditions persist for a selected period.

Abstract: A plurality of different types of operating systems in buildings organized in geographical groups, each group having a local service office, are monitored at both the local offices and central office for the presence of performance conditions and conditions indicative of an alarm condition.

Abstract: A tramper's pack comprising a sac and hip-belt secured to the sac by a load-transmitting connection comprised of a flexible webbing secured between substantially the mid-point of the width of the back of the sac and substantially the mid-point of the length of the hip-belt, the webbing being dimensioned and arranged to permit relative movement between the hip-belt and the sac in at least three directions; twisting, up and down, and in a curved plane parallel to the plane of the wearer's back. A buckle may be attached to each side of the sac and a stabilizer strap may be provided on each side of the hip-belt, each strap being adjustable in length and releasably securable to the buckle on the adjacent side of the sac. The webbing may comprise a first length secured between the hip-belt and one side of a buckle and a second length secured between the sac and the other side of the buckle, and the second length may be adjustable in length.

Abstract: A box is formed from a unitary, double-sided corrugated cardboard blank having a plurality of scored lines which enable a set up in box form. A bottom panel of the box has cemented thereto a single-sided, fluted corrugated cardboard medium with the fluted side facing upwardly. A moisture-resistant glue is used between the smooth faces of the fluted corrugated medium and the confronting liner of the blank to provide an impenetrable barrier which prevents grease from penetrating through the box. The boxes are manufactured on a conventional production line which is modified by, in effect, running one stage in a reverse direction in order to invert the single-sided medium and to apply the glue in a different manner to establish the moisture barrier.

Abstract: Apparatus in generally unitary machine form for the mechanical, automatic installation of tubes in an assembly of header plates and baffles to produce a tubular heat exchanger core or the like. Tubes are inserted one at a time in perforate parts held in a holding fixture with a mounting table and the holding fixture being capable of movement in different senses. A tube delivery arrangement features a tube support which can be rocked into and out of a support position. A guide rod is compelled to a rotary motion in its entrance into and alignment of the perforate parts.

Abstract: Elongated resilient sealing strips seal the spaces between pairs of adjacent articulated traction shoes of a removable track for tires. Each sealing strip is of chevron-or V-shaped cross-section and is integrally molded of the belt. Each leg of the chevron or V is provided with a surface for engagement with the surface of one of said traction shoes. Biasing means may be incorporated into the sealing strip to further assure sealing engagement. The composition of the strip may differ from that of the outer elastomer layer of the belt.
