Abstract: An apparatus and method for producing a shifted angle fabric and the product produced thereby. The apparatus includes a supply of fabric and a differential tenter frame. The differential tenter frame includes a frame, a pair of opposed, constant path rails and a differential drive. The differential tenter frame is located downstream from the supply of fabric for receiving the opposing edges of the fabric and advancing the opposing edges at different speeds to shift the weft angle of the fabric as the fabric travels the length of the differential tenter frame. A high velocity, low heat drying range adjacent to the differential tenter frame simultaneously dries the fabric as the fabric travels the length of the differential tenter frame. A take-up roll downstream from the differential tenter frame then takes up the dried fabric.

Abstract: A method and apparatus are described for accurately measuring the weight of a moving stream of particulate material at different flow volumes. The apparatus includes a dynamic measurement device with a deflectable curved pan for measuring the amount of material flowing along a pathway; a supply source for discharging material along the pathway; and a gate valve having an inclined gate member with a leading edge controlling the volume of material discharged from the supply source, the valve reducing the height of discharge of the material above the dynamic measurement device proportional to the increase in the flow volume of material being discharged. A gate valve is also described that includes a gate member with a fully open position and a fully closed position, the valve aperture being open a width determined by the bridging characteristics of the particulate material being discharged when the gate member is in the fully closed position.

Abstract: An improved seating apparatus for an aircraft includes a seat assembly and a quick install track fitting assembly for securing the seat assembly to the aircraft. In a preferred embodiment, the quick install track fitting assembly is made up of a track fitting body for insertion into an aircraft seat track and a manual lever that is pivotably attached to the track fitting body. The manual lever has a lever release position and a lever lock position. A force bearing plunger is movably attached to the manual lever for transferring force to the aircraft seat track. The force bearing plunger has a track release position and a track lock position, wherein both positions correspond to the lever release and lever lock positions of the manual lever. A lock may also be provided for maintaining the plunger in the track lock position when the manual lever is in the lever lock position.

Abstract: A separator for separating F.O.G. from an effluent that contains F.O.G. includes a tank, an inlet to the tank for receiving effluent that contains F.O.G., and an outlet to allow grey water to leave the tank. The tank has a size to enable stratification of a layer of F.O.G. present in the tank on water in the tank, and first and second thermocouples are positioned at differing levels in the tank. Conductors couple the thermocouples to sensors, and differing voltages in the thermocouples can be sensed to determine if the thermocouples are surrounded by F.O.G. or water.

Abstract: A high-speed actuator moves a valve stopper to a selected position to control material flow. The actuator includes a rod carrying first and second axially spaced solenoid armatures attached to the stopper. First and second solenoid coil surround and are spaced from the rod to bias the first solenoid armature along with the rod and valve stopper. A linear variable differential transformer (LVDT) responsive to the position of the second armature determines the instantaneous position of the valve stopper. A valve position control circuit receives a valve position set point from a user's input, and a valve position feedback signal from the LVDT. The valve position control circuit includes first and second solenoid coil drive signals that urge the first armature and stopper to the valve position set point. A signal generator circuit vibrates the valve about a set point to enhance material discharge.
