Abstract: A musical instrument slide including a body portion and a light source. The light source includes a switch for selective activation, enabling the slide body to emit light when activated. As the musician moves the slide across the strings as the instrument, such as a guitar, is played, a visual effect is created by the movement of the light. The body portion preferably is constructed of a material to pass light therethrough, and can be either wholly or partially clear or translucent, or a combination of both. Alternatively or in addition to the light source, the slide body can include an eccentric motor that causes the slide body to vibrate. This vibration, in turn, causes vibration of the guitar strings, or other string instrument, as the slide is positioned on the strings, or moved along the strings, by the musician.

Abstract: A machine for packaging stacks of articles into containers using selectors for grouping the article stacks. The selectors include arrays of vertically spaced wedge members which engage the articles in each stack. The wedge members are aligned with slots in comb-like guide rails and operate to form groups of predetermined numbers of stacks of articles while keeping the articles in each stack in vertical alignment as they progress through the machine into the containers.

Abstract: A packaging machine (5) for moving a spaced series of groups of containers along a path of travel in a packaging machine line is disclosed. The packaging machine includes a variable pitch lugged conveyor belt assembly (12) having a pair of conveyor chains (61, 62) equally spaced from a longitudinal axis extending along the path of travel, and a pair of generally parallel side guides (17) mounted one each on a pair of accessory rails (14) movably supported on the framework (7) of the packaging machine, and extending along opposite sides of the path of travel. The conveyor chains are constructed to be moved laterally toward and away from each other, and the side guides are constructed to be simultaneously moved laterally toward and away from the conveyors with the accessory rails, respectively, as the conveyor chains are moved.

Abstract: A self fastening plastic guide for attachment to a metal guide rail having openings formed therein has a first guide member and a second guide member. The guide members are provided with protruding locking tangs that lock the members to each other when the locking tangs are snapped together. In use, the first and second guide members are snapped together with their tangs extending through the openings in the guide rail to secure the guide to the rail.
