Abstract: A self-extinguishing torch for use in theatrical environments includes a supporting basket having a support for torch fuel. The supporting basket includes a screen providing side ventilation for containing torch fuel on the support and admitting air through the side ventilation to burn torch fuel. The supporting basket has fuel, which provides torch lighting. A container having an opening for receiving, surrounding, and containing the supporting basket has a handhold remote from the container for permitting the container to be held by a hand. A normally closed top is provided for moving from an open position to a closed position over the container with the supporting basket therein. The normally closed top is biased to the open position when the supporting basket protrudes from the container at the normally closed top.

Abstract: A high impact resistant rotationally molded door and process for molding the door has the hinge post integrally attached to the rotationally molded skin of the door. A hinge member is provided that has a perforate U-shaped metal sheet bonded to preferably the upper portion of the hinge post. The sides of the U-shaped metal sheet are spaced sufficiently apart so that registration with the subsequently rotationally molded plastic skin of the door occurs. This hinge member at the perforate metal sheet rapidly heats during rotational molding. The perforate metal thus bonds to integrally mold with the skin of the door. This bonding occurs as the hinge post is molded within the hollow door construction along its hinging edge. The hinge member attaches at the perforate U-shaped metal sheet to the skin of the door while all other portions of the hinge post are free to move with respect to the door. The door is thus formed without door warping during curing and shrinking of rotationally molded plastic door body.

Abstract: In combination with a slipform paver, a new chain feeder is disclosed which is contained within the profile of a slipform paver. The chain feeder is used in combination with a plurality of dowel bar inserter stations. A single file dowel bar path is provided immediately above the plurality of dowel bar inserter stations overlying an upper dowel bar shuttle for each inserter station. The feeder includes a plurality of feeding lugs for pushing dowel bars along the single file dowel bar path parallel to openings in the upper dowel bar shuttle. This enables dowel bars to fall into the upper dowel bar shuttle until all inserter stations are loaded with dowel bars. When the dowel bars are inserted, the upper dowel bar shuttle moves relative to the lower dowel bar shuttle. This permits an upper shuttle bar opening in the upper dowel bar shuttle and the lower shuttle bar opening in the lower dowel bar shuttle to move into registration one with another.

Abstract: A dowel bar inserter kit is used, typically in combination with a paver. The dowel bar inserter kit is removably detachable from the paver and includes at least two laterally extending support beams supported from the paver extending away from and behind the paver over the formed plastic concrete slab. A plurality of support carriages move synchronously on each laterally extending support beam towards and away from the supported frame of the paver. A suspended dowel bar inserter pan is attached at distal ends to the support carriages, the suspended dowel bar inserter pan defines apertures for insertion of dowel bars through the suspended dowel bar inserter pan. The dowel bar inserter pan has a medial dowel bar insert pan hinge to enable the suspended dowel bar inserter pan to crown with respect to the freshly placed plastic concrete slab. An inserter beam is supported at distal ends to the support carriages.

Abstract: A belt mounted support and a group of bags for support on the belt mounted support is used in the harvest of produce. The belt mounted support includes a tube and a belt mounting loop connected to the tube. A bag supporting rod is threaded through the tube to freely rotate with two hooked bag supporting ends. A group of bags is supported on the belt mounted support, each bag formed from perforate plastic sheet. Each individual bag has a front rectilinear panel, a rear and larger rectilinear panel, and a folded gusset at a bottom of the bag folded upward between the front rectilinear panel and the rear and larger rectilinear panel. Logo on the bags is formed from an outside of the bag to be read from an inside of the bag whereby the bag is manufactured in an inverted disposition with respect to the logo. The group of bags is registered one to another at a rear panel protrusion.

Abstract: An analysis system, in particular for medical analysis work for carrying out clinical-chemical and immunological analyses, comprises an analysis appliance and at least one system-reagent carrier. The system-reagent carrier has at least one cuvette which is pre-filled with a test-specific, preformulated, wet-chemical system reagent, as well as the measuring cuvette.

Abstract: A self-test system for a nuclear power plant, nuclear reactor protection system is disclosed. Nuclear protection systems are the electronic controls, typically including circuit cards, located intermediate between sensors (as for detecting core overheat) and a control (as for providing rod injection to shut down a reactor). Constant surveillance of the nuclear system protection system is provided by a microprocessor that serially addresses protection system circuit cards and loads them at pre-determined input points with test commands. The addressed cards are thereafter simultaneously activated by a system-wide command. The test command is a pulse which is so short in duration that its affect is transparent to the system and cannot cause overall system operation. The pulse passes through the actuating electrical components to verify, on the real actuating path, the operating integrity of the system.

Abstract: An audio signal is connected to one of two orthogonal deflection means on a kinescope and the audio signal phase shifted by 90 degrees is connected to the other deflection means. The phase shift device shifts the phase by 90.degree. at one or more given frequencies and by different amounts at frequencies other than the given frequencies so that the shape of the pattern produced on the kinescope varies with spectral content of input signal. The phase shift device is adjustable to permit selection of the given frequency at which 90.degree. phase shift occurs. A brightness control circuit responds to the audio signal so that the brightness varies with the magnitude of the audio signal. A cathode beam control circuit for blanking the kinescope trace at a rate determined by the amplitude of the audio signal or at a rate determined by an internal osciallator. A counter circuit for use with a tri-color kinescope which switches the three cathode circuits on and off to afford color variation to the pattern.
