The at least one variable frequency driver is configured to drive at least two of the plurality of carriers along the track.

Abstract: Fiberglass batts are installed between the side-by-side studs in the interior walls of a home or building to insulate the walls and minimize sound transfer. Each fiberglass batt has a paper backing that projects from the side edges of the batt to provide for attachment to the spaced, side-by-side wall studs that comprise the internal frame to which the walls are secured. However, a significant percentage of the backing is produced with a noncompliant, reduced width and thus those batts are discarded. In the present invention a stripper mechanism between an input conveyor that receives the inferior batts and an output conveyor strips the backing therefrom so that the fiberglass may be used in other applications.

Abstract: A roller turn roller for an industrial conveyor comprises a continuous axle tube having opposed ends and a central axis of rotation, a pair of axially spaced, tapered roller bearings on the axle tube spaced inwardly from its ends, a roller shell supported by the bearings for rotation about the axis of the tube, and a pair of axially spaced retainers secured to the tube with the roller bearings disposed therebetween. Each of the retainers engages a corresponding bearing to pre-load the bearings to a desired clearance. A fastener extending across a pair of mounting bars on the conveyor, and through the axle tube mounts the roller turn roller between the bars.

Abstract: The trailing, load supporting component of a product conveyor is connected to a powered, leading component by a shock absorbing tow bar that employs relatively movable friction elements in a sandwich configuration to absorb the shock by sliding engagement at internal wear surfaces. A brake tongue slides between opposed brake pads of the sandwich which are placed under pressure against the tongue. A two-piece, telescoping tubular housing shields the brake assembly from contaminants and enhances the structural integrity of the unit.

Abstract: A concentration measurement apparatus capable of accurately measuring the concentration of suspended matter in a liquid is provided.A transmitter 1 which transmits sound waves, light waves, or the like, and a receiver 2, which is disposed in opposition to this transmitter 1, are provided, small pipes 3 and 4, which enclose the transmitting surface position of the transmitter and the receiving surface position of the receiver, and which are opened in the direction of transmission and the direction of reception, respectively, are provided, and a mechanism for filling these small pipes with a clean liquid or gas is provided.The transmitting surface of the transmitter and the receiving surface of the receiver are not contaminated by means of the deposition or generation of suspended matter, so that it is possible to conduct the accurate measurement of the concentration in a constant manner.

Abstract: A method of modeling a vehicle crash waveform to generate an infinite set of crash waveforms comprises breaking down a predetermined crash waveform into a crash pulse (signal of interest) and multiplicative noise signal. The multiplicative noise signal is then statistically characterized as a function of time. Randomly variable waveforms from a white noise generator are then modified with the statistical characterization and multiplied with the signal of interest to generate the infinite set of model crash waveforms. These model crash waveforms can then be used to evaluate the performance of crash detection system in accordance with a "Monte Carlo" probability determination technique.

Abstract: A traction wheel turn for a power and free conveyor employs a single rotary unit to effect a complete, 180.degree. reversal of the course of the conveyor. A circular track component forms a part of the free track at the inside of the turn and is carried by the traction wheel and rotates therewith. The inside wheels of the free trollies transfer from a standard, straight track section to the circular component at the turn, are carried thereby through the turn, and are delivered to the next stationary track section at the end of the turn. The horizontal space occupied by the turn is therefore, no greater than the diameter of the traction wheel.

Abstract: This invention relates to an apparatus for inserting components into workpieces, particularly for insertion of electrical components into printed circuit boards. Multiple component magazines are provided on a shuttle which places the desired component beneath an inserter. The inserter moves through a limited reciprocation to pick up a component from the shuttle, and the shuttle is withdrawn from the path of the inserter. The inserter then moves downward to insert the component. The inserter includes an ejector which maintains contact with the inserted component during withdrawal of the inserter. The ejector includes a shock absorber which gives way if unusual resistance is met during insertion. The shock absorber is spring-biased, and the degree of stiffness of the spring is adjustable.

Abstract: A rotary displacement capacitive transducer for indicating the angular position of a shaft comprises first and second cylindrical electrodes each electrode having inner and outer conducting members connected together by insulative adhesive and a part cylindrical screen mounted to the shaft is disposed between the electrodes and rotated with the shaft to vary the capacitance between the electrodes. The surfaces of the conducting members define the capacitance of the transducer.

Abstract: A circuit arrangement for measuring the ratio of first and second capacitances of a capacitance displacement transducer. An alternating signal is developed the amplitude of which is proportional to the values of the first and second capacitances during respective first and second timing periods, the alternating signal being synchronously demodulated in one phase in the first period and in the opposite phase in the second period. The demodulated signal is integrated so that the integrator is charged and discharged during the first and second periods respectively, and the ratio of the discharge time to the charge time is equal to the ratio of the two capacitances. A digitized output is provided by means of a clock pulse generator and counter.
