Abstract: A machine that receives freshly printed matter, and moves the printed matter on a belt along the machine so that the printed matter passes through an irradiation chamber where it is irradiated with ultraviolet light. The printed matter continues to move along the belt and is thereby removed from the irradiation chamber and delivered to the output end of the machine. The irradiation chamber is so constructed so as to control the intensity of the ultraviolet radiation that is delivered to the printed matter. Air moving means are also provided by which to control the maximum temperatures induced in the printed matter as it passes through the irradiation chamber. Another air moving means is employed to control the temperature of a radiator assembly employed within the irradiation chamber. A third air moving means is provided to evacuate the irradiation chamber and associated components of hot and contaminated air and to exhaust this air to the outside.

Abstract: A resilient synthetic resin toilet seat which includes a preformed stiffening portion having an internal foamed core. The core is enveloped in an infoamed self-skin. A cushioning portion is molded thereon and has an internal foamed core enveloped in a tough but resilient self-skin unitarily extending from the top and sides of said stiffening portion. A resilient synthetic resin toilet seat lid having an internal foamed core enveloped in an unfoamed skin, a method of making the seat and lid by molding, as well as molds for use in such molding, are also disclosed.

Abstract: A shaker molding assembly. The assembly includes mold halves which are urged together as they are pushed into a holder. A measuring cup can be held against the mold halves to urge them into the holder. Ribs on the mold halves cooperate with a frusto-conic wall of the holder to urge the mold halves together. A mixture of water and a molding powder are shaken together in the assembly to form a smooth mixture. The molding powder includes an alkali metal alginate, calcium sulfate, tetrasodium pyrophosphate, and a filler. The mixture sets to form a jelly-like object which dries to form a rigid object of smaller size which is a substantially exact miniature of the jelly-like object.

Abstract: A radiofrequency electrosurgical device which includes an active electrode and a passive electrode coupled to a chassis ground of a radiofrequency generator of the device. If the passive electrode is disconnected from the chassis ground, a potential develops between the chassis ground and a system ground. This potential is used to actuate a relay to disable the radiofrequency generator if the passive electrode becomes disconnected. The relay is reset when a main power off-on switch is turned to off position.

Abstract: A bushing removing tool which includes an elongated handle portion and an operative head extending transversely of the handle portion and to one side thereof. A hook projection at an end of the operative head faces away from the handle portion and is engageable with the interior of a tubular bushing while a portion of the operative head remote from the hook projection acts as a fulcrum so that the tool can be swung to cause the hook projection to free the bushing from a bushing support.

Abstract: A machine for stacking and bundling flat articles. The articles are collected in a stack on an elevator arm. The stack is compressed and advanced into a generally U-shaped basket having parallel spaced sides. The basket can swing about an upright axis and about a horizontal axis. The basket swings about the horizontal axis to a lay-over position in which the sides of the basket are upright. The stack is pushed from the basket when in lay-over position. A tray portion of the basket can be adjusted crosswise of the basket to accommodate stacks of articles of various sizes. The horizontal axis can be advanced along a 45.degree. angle to the horizontal so that the tray position at the lay-over basket position can be at the same height for various positions of the tray member in the basket.

Abstract: A machine that receives four rows of completely separated but closely spaced cartons from a customer printing and cutting press, and spaces each carton laterally and longitudinally from its neighbors for non-interference therewith. The machine aligns each independent stream of cartons with the longitudinal dimension of the overall machine and directs the streams of cartons to a switching device intended to control carton traffic to a primary automated stacking process or to an essentially secondary manual stacking process. The primary automated process passes the streams of cartons through an underlapping process, over an inspection table, through an inverting process, into a rate controlling hopper. From the rate controlling hopper, the cartons of each stream pass over a set of laterally disposed conveyors and into a discrete stack of cartons formed within a vertical hopper system that is the output receiver of this machine.

Abstract: A device for delivering pads to a machine for bundling flat articles. The device includes a first pad hopper, a first conveyor which draws pads from the first pad hopper, a second pad hopper receiving pads from the first conveyor, and a second conveyor which withdraws pads from the second pad hopper. The first conveyor is driven when the level of the pads in the second hopper falls below a predetermined level to maintain the level of pads in the second hopper. A switch operator extends into the path of pads being advanced from the second hopper by the second conveyor and actuates a switch to stop the second conveyor when a pad has been advanced to a predetermined pad delivery position. The pad is withdrawn from the pad delivery position when a pad is required by the bundling machine and is delivered to the bundling machine. A frame on which the first conveyor operates can be adjusted to swing a discharge end thereof toward and away from the second hopper to insure proper delivery of pads to the second hopper.
