Abstract: A multipurpose construction gauge to ensure installation of pre hung windows and doors within their mounting frame openings in a plumb, square and level manner with the inner sill gapped flush with later installed sheet rock. Other applications include masonry.

Abstract: The first stage buckets have airfoil profiles substantially in accordance with Cartesian coordinate values of X, Y and Z set forth Table I wherein X and Y values are in inches and the Z value is non-dimensional along the bucket centerline coincident with a turbine radius and convertible to a Z distance in inches from the turbine axis by multiplying the Z value by the height of the airfoil and adding the root radius to the result. The X and Y distances may be scalable as a function of the same constant or number to provide a scaled up or scaled down airfoil section for the bucket. The nominal airfoil given by the X, Y and Z distances lies within an envelop of ±0.160 inches.

Abstract: An inter-axle differential assembly having a lubrication pump is provided. The pump is disposed between the input and output shafts of the differential within a bore defined by a side gear coupled to or integral with the output shaft. The pump includes a housing that defines first and second ports and includes an arcuate groove in a radially outer surface. A pin extends radially inwardly from the side gear and is received within the groove. The groove and pin cooperate to enable rotation of the entire pump relative to the side gear and to thereby exchange the positions of the two ports. In this manner, the assembly provides a reversible pump that provides lubricant only during relative rotation between the input and output shafts of the differential.

Abstract: Rigid cover panels of the cover for grain storage tubes on combines, harvesting machine, are preferably fabricated of double-wall plastic to limit weight of the cover while providing desired strength and rigidity. The rigid cover panels can be pivoted about top edges of an underlying grain tank whereby the cover panels function as a height extension of the underlying tank, thus to increase the grain-carrying capacity of the tank. Flexible transition panels are preferably mounted to the rigid cover panels to bridge spaces between edge regions of the rigid cover panels when the rigid cover panels are raised to their upright, tank-extending orientations. A preferably single underlying actuator in the tank, in combination with mechanical linkages, can simultaneously raise all the rigid cover panels, all the flexible transition panels, and the discharge end of a clean grain elevator which discharges grain into the tank.

Abstract: A turbine includes a row of blades each having an integral airfoil, platform, and dovetail. Each platform has opposite first and second side edges corresponding with the opposite pressure and suction sides of the airfoil. The platform first side edge is radially higher than the platform second side edge continuously between opposite forward and aft edges of the platform. In this way, adjacent platforms define a down step therebetween for preventing obstruction of combustion gases flowable downstream thereover.

Abstract: A hollow cooled turbine airfoil is provided having pressure and suction side walls and a plurality of trailing edge cooling passages that feed cooling air bleed slots at the trailing edge. The airfoil trailing edge is selectively thickened in the root portion so as to allow shortened trailing edge slots, thereby improving trailing edge cooling and reducing mechanical and thermal stresses.

Abstract: A door and housing assembly for controlling air flow through the housing. The housing is adapted to be mounted in a ventilating system for controlling the direction and flow of air passing through the system. The door is actuated to move between two end positions where the respective air pathways are each sealed. The door can be positioned at any location between the end positions to control air flowing to the respective air pathways. The door includes guide pins on edges thereof that move along slots located in the inner sidewalls of the housing and guide the door between its end positions to locate the door in selected intermediate positions thereof. The slots for guiding the door may be steeply angled with respect to the seals so as to create minimal wiping of the respective seals upon engagement and dis-engagement between the door and seals at end positions of door travel.

Abstract: An apparatus for delivering a gaseous product includes a horizontal container having inlet and outlet ports, an elongated hollow tube inside the container, a purifying medium inside the tube, inlet and outlet control means adapted to control delivery of the fluid to the inlet port and to control delivery of a gaseous product from the outlet port. The tube has a first opening, a second opening spaced apart from the first opening, and an internal axis between the first and second openings. The first opening is in fluid communication with the outlet port and the second opening is in fluid communication with a vapor space in the container. A portion of the internal axis adjacent the second opening is at an angle greater than zero degrees relative to the horizontal longitudinal axis of the container. Each of the inlet and outlet control means preferably are single ported valves.

Abstract: A remote inventory system employs unique serial numbers ‘burned’ into each board/software routine desired to be tracked. These boards/routines find their way into machines at various remote sites each connected to a base by a remote link. A monitor program is run by a microprocessor resident at each remote site. It periodically collects the serial numbers and other information regarding the boards/routines, and transmits the information to a base running a base program. The base program interacting with a database, determines the hardware/software configuration, performance history, tracks the lifecycle of a board/routine. It may also be possible to determine remote sites running unauthorized ‘protected property’.

Abstract: Waste tires are disposed of in a cement-manufacturing or other mineral-burning process by introducing the tires into the hot gas stream at at least one point between the mineral-inlet end of a rotary kiln and the lowermost cyclone of an associated preheater system, e.g. into the gas stream within a precalciner vessel or riser duct, the tires being maintained in contact with the hot gas for a sufficient period to effect at least partial combustion of the tires. As an alternative, the tires may be introduced into a Lepol grate preheater.

Abstract: Emission of nitrogen oxides from a mineral-burning process, for example a cement-manufacturing process, is reduced by passing the exhaust gas from the rotary kiln in which the mineral raw materials are burnt to a combustion zone in which solid fuel elements, for example waste tyres, are maintained for a sufficient period and at a sufficient temperature for at least 30% by weight of the volatile combustible content of the solid fuel elements to be combusted, the combustion zone comprising at least one region in which the combustion of the solid fuel elements occurs under sub-stoichiometric conditions. The solid fuel elements may be introduced into the hot gas stream at at least one point between the mineral-inlet end of the rotary kiln and the lowermost cyclone of an associated preheater system, e.g. into the gas stream within a precalciner vessel or riser duct. Preferably, tertiary air from a clinker cooling apparatus is supplied downstream of the combustion zone (relative to the flow of kiln exhaust gas).

Abstract: An asphalt release agent for preventing hot road asphalt, especially polymer-modified asphalt, from sticking to surfaces of delivery truck beds is provided. The release agent includes a water-based mixture of polycycloaliphatic amines and polyalkylene glycols. The release agent is applied onto the truck beds to create a slippery non-stick surface so that the road asphalt which comes in contact with such truck bed surfaces will not adhere.

Abstract: A method is provided for increasing the release temperature from the fuser in copying and printing processes comprising the steps of forming a toner layer on a receiver with an imagewise overlay toner on top and fixing the layers of toner by contact with a fuser.
