Abstract: A grit blasting arrangement for cleaning chemical reactor tubes includes means for ensuring the grit blast nozzle is coaxial with the longitudinal axis of the tube to be cleaned. The grit blasting device for cleaning tubes spaced apart by upper and lower tubesheets. The grit blasting device includes a grit blast nozzle mounted on a positioning frame and projecting outwardly with an outlet directed into a tube opening during a cleaning operation. The device includes a plurality of stop pins mounted on the positioning frame designed to abut a tubesheet and to define an imaginary plane coplanar with the tubesheet. The plurality of stop pins when abutting the tubesheet prevent the outlet of the nozzle from extending into the tube causing a venturi effect.

Abstract: An example includes a segment collector to: access impression records indicative of media access segments, the media access segments including start times and end times corresponding to media accessed by a panelist; and determine ones of the impression records that include a watermark corresponding to a first media platform presenting the media; a segment classifier to convert a first one of the impression records including the watermark to a converted impression record; and combine the converted impression record corresponding to the first media platform and a second impression record corresponding to a second media platform; and a media creditor to generate audience measurement metrics based on the combined impression records.

Abstract: An applicator including: a frame with hopper mounted thereon to hold and dispense a granule product, the hopper including an electronically controlled gate(s); a tank to hold a liquid product; a electronically controlled spray tip(s) to dispense the liquid product; a spray pump located between the tank and spray tip(s); an operator control interface for receiving input from an operator; a control coupled to the operator control interface, the electronically controlled gate(s), and the spray tip(s), where the control receives input, dispenses the liquid or granule product based on the input received from the operator control; where when the liquid product is dispensed, the control provides a signal to the spray tip(s) to regulate a flow of the liquid product, and when the granule product is dispensed, the control provides a signal to the electronically controlled gate(s) to regulate a flow of the granule product.

Abstract: An open field game arrangement includes glowing targets and provides responses, such as lights and sounds, when the targets are hit.

Abstract: Methods and apparatus are disclosed to identify users associated with device application usage. A disclosed example method involves obtaining demographics of persons to participate in a panel for an audience research study, identifying a set of applications to be monitored, providing devices associated with the persons in the panel with a meter to record usage of the applications and with a user-to-application associator, the user-to-application associator to define associations between the applications to be monitored and the persons associate with the device before the applications are launched, receiving data from a first one of the devices identifying a first one of the persons as a primary user of a first one of the applications in the set of applications, receiving data from the first device identifying usage of the first application, and associating the demographics of the first person with the usage of the first application.

Abstract: A bracket for securing a bucket. The bracket includes a longitudinal strip comprising a body with an upper end and a lower end. The upper end has a U-shaped hook extending downward toward a middle portion of the body with a length of at least about ? of a length of the body. The hook is spaced apart, biased toward and substantially parallel in relation to the body. The hook is configured to retain at least an upper portion of a bucket with the distal end of the hook projecting outward to form a tab. The lower end has a lip extending upward and away from the body for supporting a bottom of a bucket. The bucket is mounted onto the bracket by securing it to the lip and is retained on the bracket by the hook.

Abstract: A climbing structure includes a support frame and a wall assembly. The wall assembly comprises a chain arranged as a loop with an array of climbing panels attached to the chain so as to maintain a configuration that rotates the climbing panels downward as the user climbs to achieve a continuous climbing experience. A lower shaft assembly includes a shaft that rotates based on an angle of the wall assembly. A sprocket is mounted to the shaft such that the shaft and the sprocket rotate independently to maintain tension on the chain as the climbing panels rotate downward. A cable hub assembly is rigidly attached to the shaft and secures a cable that is attached to the support frame. A disc braking system includes a disc rigidly attached to the shaft and a caliper mounted on bearing bolts such that the disc braking system fixes the angle of the wall assembly without affecting the continuous climbing experience.
