Abstract: A convenient, safe and economical packaging system has an open receptacle that collapses to a reduced closed receptacle for storing debris. An outer sleeve and a container are connected through at least one accordion section. An accordion section folds by pushing the container into the outer sleeve collapsing the open ashtray receptacle to the closed receptacle. A removable lining may optionally cover the walls of the closed receptacle. With the container pulled out the open ashtray receptacle is easily assessable through an access hole in the sleeve. A folded cutout attached to a panel of the sleeve and a bottom of the container covers the access hole in the closed position. The packaging system is particularly useful for packaging cigarettes and can be used several time before emptying the closed receptacle.

Abstract: A process is disclosed for removing particulate product from a fluidized bed reactor to optimize, within the constraints of the product removal cycle, conservation of gas in which the product is entrained. Data are compiled on the time required for equalizing pressure between product discharge tanks, and these data are used to determine the optimum times for various valves to be open. Product movement steps and equalization steps can be performed simultaneously.

Abstract: A new Wheelbarrow Rear Wheel System for improving the ease of use of a wheelbarrow. The inventive device includes a frame assembly secured to the underside of the tray of a wheelbarrow adjacent the rear end of the tray and a wheel assembly coupled to the frame assembly. The wheel assembly includes a pair of spaced wheels and is adjustable relative to the frame assembly so as to enable a user thereof to raise and lower the rearward portion of the wheelbarrow.

Abstract: A portable scaffold adapted to be utilized with a building having a vertical wall. Also included is a plurality of supports each with a generally L-shaped configuration. Each support comprises a first vertically oriented elongated side with a plurality of linearly aligned mounting holes formed therein for allowing removable coupling with a plurality of linearly aligned mounting pegs situated on the wall. A second horizontally oriented side is integrally coupled at an inboard end thereof to an upper end of the first side of the support. In use, the second sides of the supports are situated at an equivalent height. Finally, a plurality of elongated planks are adapted to be removably positioned lengthwise across the second side of each support for supporting weight thereon.
