Abstract: A modular gas cleaner can consist of an elongated box having an inlet opening and an outlet opening. The interior of the elongated box is divided into a plurality of elongated passageways by partitioning means within the box. The internal partitions of the box define a plurality of openings so that gas introduced into the inlet opening of the box must travel the length of each passageway prior to passage out of the outlet opening. Electrodes are located within each passageway and electrically isolated from the box to permit the electrodes to be charged to high voltage. The plurality of electrodes are connected with a high voltage supply to create an electrostatic charging and depositing field within the passageways of the box. The gascleaner drain openings provided in the internal partitions which lead to a collecting tank at the low point of the elongated box.

Abstract: A security door system includes an actuator mechanism housed in a box-like, closed housing to minimize the possibility of tampering with the actuator mechanism such as would permit unlawful entry through the door. The actuator mechanism drives one or more, and illustratively two, bolts which extend horizontally across the door. One of the bolts enters a receiver in the jamb along the edge of the door opposite the hinged edge. The other bolt enters a receiver provided in the jamb along the hinged door edge. The security door system further includes a jamb and frame construction in which the jamb and surrounding frame cooperate to provide the bolt receivers. A metal reinforcing plate which is fixed to the frame by long wood screws, or the like, forms a wall of the receiver. This metal walled, deep receiver is less susceptible to damage by tampering, such as by springing the jamb or ramming against the door, than prior art security door systems.

Abstract: An oven for curing coatings on articles removes the volatile components of the coating by a heated circulated atmosphere directed at high velocity at the coated articles and increasing in temperature between the entrance and the exit of the articles from the oven. Prior to their exit from the oven, the coated articles are exposed to infrared radiation in relatively still air to effect the final curing of the coating. The oven enclosure includes an open portion and a ducted portion. The ducted and open portions of the oven enclosure and the heating means are arranged to contribute to the effective use of energy. Within the ducted portion is a removable fan means supported and driven from outside of the oven enclosure. The ducted portion of the oven communicates with an exhaust opening in the oven enclosure having a damper valve that can be automatically controlled to permit exhaust when the level of the volatile coating material components in the oven atmosphere exceeds a preset amount.

Abstract: A plural component dispensing system includes supplies which furnish first and second components, such as a resin and catalyst, under pressure to a hand-held dispensing device having first and second valves, respectively. First and second passageways lead from the first and second valves to a mixing chamber in which the components are mixed, and from which the components are ejected. Upon mixing, the components are subject to increasing viscosity and hardening. A third valve controls flow of a purging medium from a supply of such a medium to the mixing chamber. A sensing device, such as a pressure sensor, senses the orientation of either/or both of the first and second valves. When the first and second valves are moved to positions to halt the flow of the two components, the sensing device generates a signal to start a first timing device.

Abstract: A combined engine flywheel and centrifugal clutch driver for a rotary lawn mower blade. Two heavy circular plates, as a quarter-inch steel plate, of large diameter, e.g., six inches, are riveted together against three peripherally spaced pairs of spacer slugs stamped from the same material, and against a central shouldered hub. This forms a rotor of sufficient rotational inertia when mounted on the depending shaft of a mower engine to provide the principal flywheel effect for an engine having a relatively lightweight magneto and fan rotor at its top end.

Abstract: A system for allocating energy adapted to be coupled to a plurality of conditioning equipment systems utilized to alter a plurality of corresponding first conditions. Thermal sensors for monitoring the conditions in each of a plurality of environments are coupled to allocation circuitry which provides for activation of control channels of the allocation circuitry in an order determined by the relative demand for conditioning of the plurality of environments. When two or more environments are determined to have the same demand for conditioning, the control channels of the allocation circuitry are activated in a controlled order. When a predetermined number of control channels have been activated, the process of allocation is terminated by the allocation circuitry. When more than the predetermined number of control channels is activated in case of a failure of the system, an alarm is activated and all previously activated control channels are deactivated.

Abstract: Implantates are packaged in means capable of aseptic treatment and forming a closed cell having a portion adapted for engagement, rupture, and entry by a tool that permits removal of the implantate for use without handling of the implantate by the user. In such a package, the closed cell is formed by a film which includes portions shaped to assist rupture and entry of the cell by the tool and to assist in encompassing the implantate within the tool for its removal from the cell. The tool used in this system can be the means used to implant the implantate subcutaneously in the body of an animal. Thus, using the system of this invention, an implantate can be provided within a closed cell which is capable of aseptic treatment and transported to a remote site for use. At such a site, the closed cell can be ruptured with an implanter and the implantate can be encompassed within the implanter and removed from the cell for implantation.

Abstract: An imbalance-determining system for a dynamic balancing machine for two-plane balancing of rotary elements such as vehicle wheel-and-tire assemblies includes a chuck and spindle mounted in a spindle housing in vibration-isolation orientation on a machine base. A drive mechanism includes main and auxiliary motors mounted on the machine base. The rotary element is brought to speed by a drive wheel mounted on the main motor to move between a driving orientation in contact with the rotary element and a storage orientation out of contact with the rotary element. A lightweight belt coupling the spindle to the auxiliary motor transmits power from the auxiliary motor to the rotary element. Once the rotary element is accelerated to the desired rotation frequency, the drive wheel is moved out of contact with the rotary element and the auxiliary motor is energized to maintain the rotary element rotation rate at about the desired frequency of rotation with little effort.
