Abstract: The present invention comprises a cart having a base and three sidewalls extending there around and upward therefrom. Four wheels are secured at bottom corners of the sidewalls to provide for easy mobility of the cart. A pair of partial doors are hingedly secured to and extend along end edges of two opposing sidewalls for permitting partial coverage of a fourth side of the cart. Each partial door includes a spring biased manually operable pin for cooperating with a plurality of slots in the cart base. In this manner the doors can be positioned from an orientation substantially coextensive with a front edge of the cart base, to positions wherein the doors are oriented inwardly of the cart loading interior space. Each door is secured to its respective sidewall in a manner wherein it can be lifted a distance sufficient to lift the pin thereof free from and above the base slots.

Abstract: A shelf slide and shelf using a plurality of such slides is shown. The slides are releasably securable to wire supports used to form a display shelf. The slides are made of an extruded material having a lower coefficient of friction than the shelf wires and facilitate the movement of product on the shelf from the rear of the shelf to the front of the shelf under the force of gravity. A universal mounting device for permitting the use of a particularly sized shelf with existing shelf support framework where the existing framework is not sized to support the particularly sized shelf. An air baffle mountable on each shelf is also shown for reducing air flow around the shelves for preventing frost formation on refrigerated products.

Abstract: A compact fuel fired steam generating type humidifier. The apparatus uses a gaseous fuel as the prime source of heat to generate steam used to humidify air in the heating, ventilation and air conditioning of buildings. The humidifier may be a stand alone unit that disperses the steam into the space or the steam generated by the apparatus may be dispersed in forced air flow of the building heating system. The steam generating unit includes a water tank in which there is located a combustion chamber and a heat exchanger chamber for transferring the heat from the products of combustion to the water.

Abstract: An apparatus and method for automatically loading successive layers of similarly shaped objects, such as newspaper bundles and the like, into wheeled carts. The bundles are first delivered at a controlled rate from a source thereof to a device that arranges and delivers the objects in organized groups to an initial loading position. The organized group is then moved onto a carrier from the loading position. The carrier then moves from its loading position to a position within the wheeled cart. A blocking plate serves to prevent the objects from moving with the carrier as it move back to its initial loading position wherein the objects are deposited in the cart. The cart is held on a lift and is first moved to a top loading position for receiving the first layer of bundles and subsequently lowered the needed amount for receiving successive layers of bundles.

Abstract: A newspaper bundle handling system is shown and includes a bundle arranging and loading apparatus for arranging and loading successive layers of newspaper bundles on a wheeled cart. The present invention also includes a conveying mechanism for conveying empty carts to the loading apparatus and for subsequently conveying loaded carts away from the loading apparatus.

Abstract: A direct vent gas fireplace has a firebox surrounded by an enclosure. The enclosure has an inclined surface between the top, rear and sides. The surface is inclined at approximately 45 degrees and has an exhaust opening. The firebox has an inclined surface parallel to the inclined panel and has an aperture in each side of the firebox. A duct connects each of the apertures to the exhaust opening. A heat exchanger lies between the inclined surfaces in line with the duct. The surface has a gap in it which connects through an air combustion conduit to the bottom of the firebox. The conduit may be pre-formed. An angle adaptor has an inner cap over the exhaust opening and an outer cap over the inner cap and the gap. The adaptor may be mounted vertically or horizontally. Alternatively, an inclined plate may be placed over the inclined surface with a hole concentric with the opening and of greater area. A first wall of a double walled vent duct may enclose the opening, while the second wall encloses the hole.

Abstract: A wheel lock mechanism for use in carts and the like for releasably locking an opposed pair of swivel caster wheels of such carts. The present invention includes a lever arm extending outwardly from the cart operable by the foot of an operator for moving a locking mechanism between a wheel locking position and a free wheeling position.
