Abstract: An interlock system includes first and second connectors for connecting a boom section to a boom. A first cover is provided for covering an actuator for actuating a first connector when a second connector is withdrawn from a position for connecting the boom section to the boom. A first block may also be provided for blocking a first receiver in an operative condition to prevent the first connector from entering the first receiver. The connector may be adapted for movement along an insertion axis corresponding to a first receiver on the boom section and a second receiver on the boom, and an actuator may be provided for advancing or retracting the connector, the actuator extending generally parallel to, but offset from, the connection axis. Related methods are also disclosed, as is an axially offset actuator for actuating one or more of the connectors for connecting the boom section to the boom.

Abstract: A beverage cooling device for the rapid cooling of the content of canned or bottle beverages is provided. The beverage cooling device is a handheld device that easily engages the top of a can or beverage. The beverage cooling device includes a housing with side walls for mounting a motor. A container engagement member is attached to the motor along the bottom side of the housing such that it is able to freely rotate within the side walls of the housing. The container engagement member is attached to the drive shaft of the motor such that it is able to rotate when the motor is actuated. The container engagement member includes, at its center, a central gripping member for gripping the top of containers with long narrow necks. The container engagement member further includes peripheral gripping members for engaging containers having tops of larger circumferences, such aluminum beverage containers of varying sizes. The motor is actuated by an on/off switch.
