  • Patent number: 5373954
    Abstract: A tamper indicating closure has a tamper indicating band which is retained on a container by a container neck flange without the use of a cooperating bead or flange on the tamper indicating band. The retention is accomplished by providing a flexure at the bottom of the cap skirt which permits the band to move outwardly over and under the container flange. The closure can have a tear strip which provides the flexure on the closure.

  • Patent number: 5369973
    Abstract: The invention relates to a process for bending pipes, which preferably are deformable or bendable when heated. In this process the pipe to be bent is heated, if need be, an inside support is put in, and then the bending operation is carried out. Prior to the bending operation a pipe-like inside sleeve (3) which is expandable up to a certain degree is inserted in the pipe (1) to be Dent, and the inside sleeve (3) is filled with a pressurized medium so that it comes to rest fully against the inside wall of the pipe (1) to be bent, whereupon the bending operation takes place. The apparatus for performing the process comprises an insertable flexible pressure pipe (3) of a material that expands under pressure, the ends of this pipe being fitted with sealing parts (5, 6), the outside diameter of which is not greater than the inside diameter of the pipe (1) to be bent.

  • Patent number: 5367861
    Abstract: A small riding lawn mower having a grass cutting unit suspended from a body frame between a front axle and a rear axle, an engine supported by a body frame in a position forwardly of the rear axle with respect to a longitudinal direction of the body frame, a hydrostatic transmission disposed rearwardly of the rear axle, and a driver's seat disposed forwardly of the engine. The body frame includes profile members disposed at opposite sides and extending longitudinally of the mower, and a cross plate interconnecting the profile members. A belt transmission mechanism connecting the hydrostatic transmission to an engine output shaft is surrounded by a plate frame structure formed below the body frame. The plate frame structure defines a further independent chamber for accommodating a muffler of the engine. This chamber has peripheral walls shaped to guide cooling air from the engine to the muffler and laterally outwardly of the mower.

  • Patent number: 5368340
    Abstract: A quick connect fluid coupling is disclosed for use with a fuel tank having an opening. The coupling includes a coupling body having a tubular retainer housing and a tubular fill tube which is telescopically positioned through the retainer housing. The retainer housing also includes an outwardly extending flange which abuts against the outer surface of the tank around the tank opening. The fill tube is telescopically received within the retainer housing and is movable between a locked position and an unlocked position with respect to the retainer housing. The fill tube is also smaller in cross sectional shape than the tank opening so that the fill tube can be positioned through the tank opening and within the interior of the tank.

  • Patent number: 5364077
    Abstract: The handrail assembly includes at least one tubular metal stanchion, having a base and a hemispherical cap having a threaded receiver and at least a horizontal top rail. The horizontal top rail has an inner metal pipe, an outer plastic pipe, and at least one aperture for receiving the metal stanchion. Prior to assemblage, a threaded fastener is attached to the interior of the inner metal pipe opposite the aperture. In an alternative embodiment, the hemispherical cap on the stanchion is replaced by a threaded fastener and a threaded nut is positioned within the interior of the inner metal pipe opposite the aperture. Prior to insertion of the stanchion into the aperture, at least one tubular plastic sheath, having a first end conforming with the base of the stanchion and a second end conforming with the top horizontal rail, is slipped onto the tubular metal stanchion.

  • Patent number: 5361894
    Abstract: An improved conveyor radii is provided for us with a conveyor system of the type in which two rails are spaced apart and parallel with each other and define a conveyor line therebetween. The rails are adapted to rotatably support a plurality of longitudinally spaced axles which extend between the rails and so that a portion of at least one of the axles protrudes laterally outwardly from one of the rails. The improved rail comprises an elongated one piece body which is preferably an extrusion. The body is generally L-shaped in cross sectional shape and thus has a lower and generally horizontal leg and an inner and generally vertical leg. A shield is removably secured between the upper and outer free ends of the vertical leg and horizontal leg, respectively, which encloses the outwardly protruding portion of the axles. The shield, however, is removable when required in order to provide access to the protruding ends of the axles for maintenance purposes.

  • Patent number: 5359793
    Abstract: A greeting card with removable bookmark combination comprises a sheet forming at least one leaf, an ornamented, preferably rigid sheet and a connector for removably attaching the ornamented sheet to a leaf of the card without substantially increasing the thickness of the card. Preferably, a threaded loop is wound through perforations in the leaf of the folded sheet and receives an elongated tassel tied to the ornamented rigid sheet forming the bookmark. Alternatively, the bookmark may-be retained in a relatively fixed position with respect to the sheet forming the card by slits within the sheet to form a retainer for the bookmark. The slits may be made in pairs, and multiple pairs may form straps that removably connect the bookmark ornamental indicia to the card leaf.

  • Patent number: 5357648
    Abstract: An apparatus is disclosed for washing and then drying industrial parts. The apparatus includes a housing having an inlet for receiving the parts to be washed and an outlet for discharging the parts after drying. A first conveyor has one end positioned adjacent the housing inlet for receiving the incoming parts to be washed, and a second conveyor having one end adjacent the housing outlet. The conveyors are preferably positioned in a side by side relationship and are constructed from an endless chain. A motor drives the first and second conveyors. A liquid sprayer has a plurality of outlet nozzles positioned above the first conveyor so that liquid washing fluid is directed against parts on the first conveyor. A transfer rail transfers the parts from the first conveyor to the second conveyor after washing and an air blower having a plurality of air outlet nozzles are directed towards the parts on the second conveyor to thereby dry the parts prior to their discharge from the housing outlet.

  • Patent number: 5355855
    Abstract: An integrated air/fuel sensor is disclosed for use with a gaseous fuel internal combustion engine. The sensor includes a housing having a mass air flow sensor which provides an output signal representative of the mass of air flow through the mass air flow sensor. Similarly, a mass gas sensor is also contained in the housing which provides an output signal representative of the mass of gas flow through the mass gas flow sensor. The integrated air/fuel sensor is mounted to the air and fuel supply system for the engine upstream from the internal combustion engine. The output signal from both flow sensors are provided as input signals to a circuit which calculates the air/fuel ratio to the engine and provides an output signal representative thereof to the fuel management system for the engine.

  • Patent number: 5353765
    Abstract: A fuel management system is provided for use with an internal combustion engine which utilizes gaseous fuel as the fuel source. A mass gas flow sensor is fluidly connected between the gaseous fuel source and the engine. A mass air flow meter is similarly provided in series with an air intake for the internal combustion engine and the outputs from both flow meters are provided as input signals to a microprocessor based control circuit. The control circuit calculates the air/fuel ratio of the combustible charge provided to the engine and generates appropriate output signals to a valve arrangement in series between the source of gaseous fuel and the internal combustion engine to vary the air/fuel ratio to obtain a desired engine performance as a function of the engine operating condition. An air/fuel ratio sensor is also in fluid communication with the exhaust gas stream from the engine and provides an output signal representative of the actual air/fuel ratio to the control circuit.
