Abstract: An intramedullary device for use in internal fixation of a fracture transverse to the longitudinal axis of a long bone which includes a substantially rigid center rod having a plurality of longitudinal slots extending along the length thereof. One of a plurality of generally flexible outer rods is received and retained within one of the longitudinal slots and thereby extend outwardly from the center rod. Each outer rod has a retention section angulated from the longitudinal axis of the long bone which penetrates through and is retained by the cancellous bone thereby stabilizing the fracture at the distal and proximal ends of the long bone. In order to install the intramedullary device within the endosteal canal, each end of the generally flexible outer rods are coupled to one of a plurality of extension rods of an installation device. The generally rigid center rod is introduced through the central opening of the installation device and thus extends into the endosteal canal.

Abstract: An improved contact body element, for use in forming the fill of a gas and liquid contact apparatus to produce interaction between a gas and liquid flowing through the apparatus, of the type having formed sheet members with a longitudinally extending edge of the sheet member folded over on a longitudinally extending surface of the corrugated member. This provides a strip of sheet material secured in overlapping relationship to the surface of the formed sheet member forming a full gap therebetween. An adhesive with intumescent qualities, which are triggered by heat, is applied within the fold such that the longitudinal edge and longitudinal surface in cooperation with the adhesive form a substantially rigid ply that is substantially resistant to erosion and can withstand higher compressive forces and which will expand in the event of fire, to block the openings between the sheets. The sheet edge may be slitted along its length to facilitate this blockage.

Abstract: A gas and liquid contact body for use in a gas and liquid contact apparatus in which gas and liquid flow in cross flow relationship to one another is disclosed. The contact body is formed of a plurality of sheets of corrugated material having first and second opposed edges with corrugations formed in the sheets extending at an angle to the edges and abutting each other at points in adjacent sheets to form through-passing channels for gas and liquid. The first and second edges of the sheets define gas inlet and outlet edges in the contact body. Either the gas inlet edge or the gas outlet edge, or both, have a plurality of generally channel shaped notches formed therein so that liquid flowing through the contact body will agglomerate at the notches. The agglomerated liquid will flow downwardly along the gas inlet edge of the contact body to clean the sheet at that gas inlet edge.

Abstract: A sanitary conveyor system is disclosed in which a conveyor bed, with or without curves, is mounted on a frame for movement of food trays between a plurality of work stations or movement of soiled trays from the cafeteria to the ware-washing area.

The conveyor system includes a first set of pulleys being disposed adjacent to the tail end of the conveyor beds which are horizontally aligned and angled upwardly from the box channel to the conveyor beds such that each belt in the lower return flight path of the box channel are moved upwardly to the corresponding upper flight path of the conveyor bed. A second set of pulleys is disposed adjacent to the drive end of the conveyor bed and operatively connected to a belt drive unit such that belts are moved from the upper flight path of the conveyor bed to the lower return flight path of the box channel.

Abstract: A magnetic recording medium such as a magnetic recording tape or disk is demagnetized by applying a saturating magnetic field to the magnetic recording medium, then applying an unsaturating magnetic field to the magnetic recording medium in a direction opposite to the direction of the saturating magnetic field, and finally applying an alternating magnetic field to the magnetic recording medium to remove residual magnetism which has been produced on the magnetic recording medium by the unsaturating magnetic field. The saturating, unsaturating, and alternating magnetic fields are generated respectively by a first DC erasing head, a second DC erasing head, and an AC erasing head, which are arranged at spaced intervals in the order named in the direction in which the magnetic recording medium is continuously moved.

Abstract: A bakery oven of the type employing a continuous conveyor therein for carrying goods to be baked through an oven enclosure includes an air distribution system adapted to direct heated air from near the top wall of the oven enclosure to the bottom and sides thereof.

Abstract: During a normal waste collection service, an automated loading mechanism is used to empty the contents of a bin into a refuse vehicle. The bin has a closable lid which includes a message on its underside such that the message is displayed when the lid is open. The message indicates that recyclable wastes, such as glass, paper or the like are to be collected in a subsequent collection to the normal waste collection. A lid opening device including a lever arm which operates to automatically open the lid of the bin is employed during an emptying operation so as to display the message. This message indicates to the homeowner that the required recyclable waste can be placed into the bin, and by closing the lid, the collection service is signaled to empty the contents of the bin.
