Abstract: An improved roller system includes a roller support body having a center longitudinal axis and a base wall and at least one roller unit mounted within the roller support body. Each of the roller units include a ball-retaining cavity which extends upwards within the roller support body and a generally spherical roller ball rotatably mounted there within, and a roller ball retention device rotatably retains the roller ball within the ball-retaining cavity with a lower portion of the roller ball extending below the base wall of the roller support body such that the roller support body is rollably supported on the roller ball. A main book support strut is mounted on and extends from the roller support body. At least two book pages are bound together via a book binding in a book format, and pages are mounted on the main book support strut on the roller support body.

Abstract: An improved vehicle-shaped book includes a lower chassis body, an upright book support strut and at least two book pages, each page including a middle foam plate and front and back semi-rigid paper plates mounted on and sandwiching the middle foam plate, the book pages bound to adjacent pages thereof in a book format, the book pages mounted on the upright book support strut generally perpendicular to the longitudinal axis of the lower chassis body and front and rear wheels rotatably mounted on the lower chassis body whereby the vehicle-shaped book is rollable on the wheels.

Abstract: A foldable foam-based divider device includes a plurality of panels, each panel including a middle foam plate and front and back semi-rigid paper plates mounted on and sandwiching the middle foam plate, the middle foam plate further including at least one outwardly extending connecting tab and at least one tab-receiving recess with adjacent ones of the plurality of panels connected to one another in accordion-like fashion with the connecting tab extending into the tab-receiving recess and being secured therein by connection of the front and back semi-rigid paper plates to the connecting tab. The plurality of panels is movable between a closed position with the plurality of panels forming a folded stack of generally parallel panels and an opened position wherein the plurality of panels forms an extended wall operative to selectively divide an area.

Abstract: A vehicle-shaped book of foam-based pages includes a center chassis page and at least one body page, each page being constructed of a panel of a semi-flexible foam material. The center chassis page and the body pages are bound to adjacent pages thereof in a book format. Front and rear ground-engaging wheels are rotatably mounted on the center chassis page whereby the vehicle-shaped book is rollable on the front and rear ground-engaging wheels.

Abstract: A loosely bound book of foam-based pages includes a plurality of pages, each page including a middle foam plate and front and back semi-rigid paper plates mounted on and sandwiching the middle foam plate and at least one binder slot formed in each of the pages, the binder slot extending entirely through the middle foam plate and the paper plates. At least one binding strap is extendable through the binder slot of each of the pages for binding the plurality of pages in a book and at least one releasable binding strap closure device is mounted on the binding strap, the releasable binding strap closure device operative to open and close the binding strap to permit pages to be added to and removed from the loosely bound book.

Abstract: An interactive game is contemplated having an outer container and a tray engaged within the outer container. The tray including a plurality of compartments adapted to receive and retain articles within. Openings are formed in the outer container aligned with at least a portion of each compartment. A cover is provided for selectively covering the openings and concealing the interior of the compartments. Channels are formed in the tray which extend between the sidewalls of the tray and the interior of the compartments. A book may be provided for the purposes of providing instruction or to further support the overall theme of the game.

Abstract: A kit for creating artwork such as sand painting is provided having a front cover, a back cover, and an interposed spine. The spine spaces the front and back cover when folded into a book form. The back cover extends outwardly beyond the front cover when folded and has a container mounted thereon which retains a series of dispensers therein. A booklet is mounted to the inside of one of the covers and an envelope is mounted to the inside of the other cover. A plurality of drawing sheets are provided having a base and a cover sheet. The base has a layer of pressure sensitive adhesive which is removably covered by the cover sheet. The cover sheet has perforations to define a plurality of removable portions. Each dispenser has a plurality of small color particles of a pre-selected color.

Abstract: The invention concerns a process and an apparatus for performing chemical reactions under pressure in the presence of a solid catalyst in a multi-stage reaction zone, after external intermediary thermal conditioning. This process may be used for the synthesis of ammonia or methanol or for gasoline reforming. It is characterized in that at least one reaction fluid is introduced into at least one compartment, a first reaction effluent is recovered, a heat exchange takes place, outside the reaction zone, between a first effluent and an external heat exchange medium, then the first effluent is introduced into at least one subsequent compartment and a second reaction effluent is recovered from the subsequent compartment.

Abstract: This invention relates to a method for treating residue gases proceeding from units applying the Claus reaction for the removal of sulphur and having been subjected to a conversion of the sulphur compounds into sulphuretted hydrogen.This method consists in that, prior to absorption of the sulphuretted hydrogen by a selective solvent in aqueous solution, the gases to be treated are cooled to a temperature so selected as to condense the water contained in the gases to form an aqueous effluent which is thereafter injected into the circuit of the selective solvent.
