  • Modular shutter assembly
    Patent number: 5152116
    Abstract: A shutter assembly of modular members molded or extruded from a polymeric material. Each of two side rails has a front wall and an inner wall defining a channel portion. Each of upper, and lower frame members and two louvered panel members has runners or mounting flanges extending along the sides thereof. The channel portion of each side rail has a base leg projecting from the side rail, a second leg projecting from the base leg, and a third leg projecting from the second leg toward the side rail. The third leg is spaced from the side rail by a distance approximating the mounting flange thickness when the channel portion is unstressed. The base leg flange has a groove defining a hinge. The channel portion defines a flexible mounting channel accommodating the mounting flanges despite minor dimensional variations.

  • Automatically lowering toilet seat
    Patent number: 5150483
    Abstract: An attachment for a toilet seat is provided which ensures that a toilet seat may not be left in the upright position. An arm attaches to one side of the toilet seat and projects downwardly outside the toilet bowl. The toilet seat is arranged so that it will always fall forward from any position due to the force of gravity on the seat and the leverage caused by the weight of the arm. An optional stop mechanism is provided to limit the rearward travel of the toilet seat to ensure that the seat will always fall forward. In use, the toilet seat is held in the upright position by resting the arm against the user's leg.

  • Precision thick film elements
    Patent number: 5148143
    Abstract: A precision thick film resistor has a deposited thick film conducting layer which is adjacent to and in contact with a deposited thick film resistive layer. A laser scribed line, having a width on the order of 2 mils, separates the conductive region into two parts and then extends into the resistive layer. The value of the resistor is set based on the extent that the line extends into the resistive layer. A plurality of thick film conducting elements can be formed by depositing a continuously extending thick film conducting layer on a substrate. Laser scribed lines can be used to isolate various conducting elements in the deposited film from one another. Elements are separated from one another by 2 mil wide laser scribed lines.

  • Disposable container for dispensing of photographic developing liquids
    Patent number: 5148208
    Abstract: A disposable container in the shape of a bottle made of molded polyethylene plastic serves as a reservoir for a photographic development liquid, that is circulated between the container's reservoir and a machine. The container has large planar sides to which good thermal contact is made by electrical heating pads for the purpose of heating the liquid within the container's reservoir. A substantially planar top surface of the container defines a central outlet aperture. This aperture connects to a feed tube which extends into the container's reservoir. The container is mounted upright to the machine's bottom surface by a screw collar. The machine's bottom surface is complementary to, and mates with, the container's top surface. A fluid-tight compressive seal is made in a first annular region about the container's central aperture by means of an O ring or gasket.

  • Infeed assembly for an axial-flow combine
    Patent number: 5145462
    Abstract: An infeed assembly for an axial-flow combine arranged at a forward end of a rotor which is mounted within a casing defining a transition section at a forward end thereof. The transition section has a series of spiral transport vanes on an inner surface thereof. The infeed assembly is comprised of a series of equally spaced blades. Each blade has a leading edge, an outer edge, and a material engaging surface. The leading edge of the blade, which is peripherally rounded, is swept back relative to the given direction of rotor rotation. The outer blade edge extends from the leading edge and angles relative to the transport vanes in varying degrees as the blade extends rearwardly from the leading edge. The material engaging surface of the blade has a generally concave shaped section extending axially rearward from the leading edge of the blade and which extends into a relatively flat shape section.

  • Idler sprocket mount for a crawler tractor
    Patent number: 5145241
    Abstract: An idler sprocket mount including a pair of modular block assemblies for mounting an idler sprocket for endwise sliding movement generally parallel to a track frame of a crawler tractor. Each block assembly defines a horizontally elongated channel allowing for endwise sliding movement of the frame therethrough to permit the idler sprocket to recoil parallel to the track frame. The elongated channel includes at least one bearing surface along which a wear surface of the track frame slides. A spring biased assembly provides a substantially constant vertically directed force against the frame to resiliently urge the wear surface against the bearing surface of the channel thereby automatically compensating for wear between the interfacing surface and inhibiting vertical bounce of the idler sprocket relative to the track frame.

    Abstract: A package is provided in the form of a container and closure assembly which incorporates a system for providing a positive orientation of the container closure so as to align external features of the closure and container. The container has a neck defining an opening to the container interior, an external screw thread, and a protuberance. The protuberance has generally oppositely facing abutment surfaces and at least one cam surface extending between the abutment surfaces. The closure has a skirt defining an internal screw thread for engaging the container external screw thread. The skirt defines a recess for receiving a protuberance. The recess is defined at opposite ends by spaced-apart engaging surfaces for confronting the protuberance abutment surfaces.

    Abstract: A door assembly for an axial-flow combine having a crop receiving and generally tubular rotor casting defining an elongated axis, a rotor coaxially disposed within the casing, and a vaned impeller arranged at a forward end of the rotor. The door assembly extends across and at least partially closes a forward open end of the casing. At least a portion of the door assembly has a surface configuration extending circumferentially about its outermost edge for positively moving crop material axially rearward through the rotor casing to reduce crop material repeat on the downward rotational direction side and improving endwind efficiency.

  • Carrier stock with tear-open tabs
    Patent number: 5139137
    Abstract: Carrier stock formed from a single sheet of resilient polymeric material, such as low density polyethylene, for machine application to substantially identical containers. The stock is severable to form individual carriers with three longitudinal rows of container-receiving apertures, as defined by band segments, which include cross segments formed with tear-open tabs. The cross segments formed with such tabs are slitted so as to define a series of frangible bridges, which are staggered transversely, and which can be easily torn by a user pulling on such tabs. Also, a distal portion of each tab is connected to another band segment by a frangible web, which is slitted.
