Abstract: An on-line material analyzer which utilizes pulsed neutron generation in order to determine the composition of material flowing through the apparatus. The on-line elemental material analyzer is based on a pulsed neutron generator. The elements in the material interact with the fast and thermal neutrons produced from the pulsed generator. Spectra of gamma-rays produced from fast neutrons interacting with elements of the material are analyzed and stored separately from spectra produced from thermal neutron reactions. Measurements of neutron activation takes place separately from the above reactions and at a distance from the neutron generator. A primary passageway allows the material to flow through at a constant rate of speed and operators to provide data corresponding to fast and thermal neutron reactions. A secondary passageway meters the material to allow for neutron activation analysis. The apparatus also has the capability to determine the density of the flowed material.

Abstract: A fluid actuated gripper mechanism with opposed gripper slides received on ways of a housing and actuated by opposed pistons received in a common bore. Each piston is transfixed by a coupling pin secured to one slide. Movement of the pistons and slides is synchronized by a lever pivotally mounted in the housing and having equally radially spaced apart and parallel elongate cam slots in which the coupling pins are received.

Abstract: A fluid actuated linear slide for producing linear movement has a rigid body with a pair of spaced apart parallel bores for slidably receiving a pair of guide rods and a mounting plate fixed to one end of the guide rods. A fluid actuated cylinder is carried by the body between and parallel to the guide rods and has a casing and a rod slidably received in and extending from one end. The rod is connected with the mounting plate for reciprocating the plate and the guide rods with respect to the body. The linear slide is constructed in such a manner that two or more of the slides can be attached in series for producing movement in one or more paths.

Abstract: A plurality of solenoid control valves each mounted on a module of a manifold with a terminal block for each valve removably received in the manifold and having at least three terminals. A printed circuit board with a microprocessor and a coil driver mounted on the board has three spaced apart electric connectors releasably secured to separate terminals of the same terminal block and each having a shank received in a hole through the circuit board and electrically connected to a printed circuit on the board by solder to both mount and support the circuit board on the terminal block and provide output of the coil driver to the coils of two solenoids for controlling the application of electric power to them. An auxiliary circuit board with another coil driver and electric connectors mounted on another terminal block is daisy chained with the microprocessor for controlling the application of electric power to additional solenoid coils.
