  • Patent number: 4557400
    Abstract: A carrier unit adapted to be converted into a bulk material carrier including a container having a floor and two parallel substantially vertical walls. The floor has at least one floor panel movable between a storage position and an operative position and at least one floor section movable between a storage position and an operative position. The floor panel when in the operative position and the floor sections when in the operative position cooperate with portions of the walls to define a compartment and to form an opening in the floor, which communicates with hoppers depending from the floor. A flexible liner is mountable in the compartment, when the floor panel and the floor sections are in the operative positions, for holding bulk material. The flexible liner includes an inlet for charging bulk materials into the liner compartment and an outlet cooperable with the opening for communicating the interior of the liner compartment with the exterior of the compartment for discharging the bulk materials.

  • Patent number: 4553778
    Abstract: An implement snubbing device positionable between a boom and an implement including a compressible member positioned generally between, and having a longitudinal axis extending generally between, the boom and the implement. A boom connecting mechanism connects the compressible member to the boom, and an implement connecting mechanism connects the implement to the compressible member. The compressible member has a compressing mechanism which comprises the compressible member along the longitudinal axis and is actuated by the swinging movement of the implement about a lateral axis generally perpendicular to the longitudinal axis. A second compressing mechanism compresses the compressible device along the longitudinal axis and is actuated by the movement of the implement about a second lateral axis generally perpendicular to the first lateral axis.

  • Patent number: 4552855
    Abstract: Zeolite-metal catalysts having a substantial amount of catalytically active metal, e.g. iron, deposited in the cavities of the zeolite in zero-valent, small cluster form, are prepared by vaporizing the metal under low vapor pressure conditions in the vicinity of an organic liquid solvent, e.g. toluene, such that the metal dissolves in the solvent as a labile solvated zero-valent metal complex. This complex is contacted with the zeolite so that the complex diffuses into the cavities of the zeolite. Upon subsequent warming the solvated metal complex decomposes, leaving zero-valent small metal clusters in the zeolite cavities.

  • Patent number: 4548100
    Abstract: A transmission for motor vehicles having a conical-disc band transmission placed in a casing, a reduction gear and, if necessary, a differential. In order to achieve an optimum transmission-ratio range for motor vehicles and good efficiency, the reduction gear contains two forward speeds and is connected to a fixed gear on the power take-off shaft by means of an additional fixed gear. The driving disc pairs of the conical-disc band transmission are located directly on a section of the drive shaft and on the power take-off shaft. The reduction gear and the conical-disc band transmission can be actuated by means of conventional synchronous clutches. The transmission case is longitudinally fitted with a center wall which subdivides the space into two compartments, one of which is closed by a front cover and the other by a rear cover. While one compartment contains the reduction gear and, if necessary, the differential, the other compartment contains the conical-disc band transmission.

  • Patent number: 4545300
    Abstract: A screen printing assembly attachable to a silk screen frame including a support frame positionable adjacent and attachable to the screen frame. A squeegee and flood bar assembly deposits and forces ink on and through the screen and onto a substrate disposed adajcent the screen. The assembly includes a mechanism movable along the support frame and the screen frame and a flexible sheet is attached to and moves with the mechanism. The flexible sheet is sealed to the support frame, and forms in part a sealed chamber in which the squeegee and flood bar assembly deposits the ink on the screen. Solvents can be sprayed into the sealed chamber which contains the solvent so that it does not escape not the atmosphere. An inert gas is injected into the chamber displacing the oxygen in it so that the ink does not dry out as rapidly, and safely maintaining the contained solvent. A method for screen printing using this sealed chamber.

  • Patent number: 4535862
    Abstract: A cooling system for a vehicle's engine including a plenum chamber disposed in the vehicle's body, an exhaust system, and a radiator disposed between an interior portion of the body including the engine and the plenum chamber and operatively connected to the engine. A fan is mounted in the plenum chamber between the radiator and the exhaust system and adjacent the radiator and, when operated, air within the interior portion of the body including the engine is drawn through the radiator and the plenum chamber and expelled through the exhaust system. A cover member is removably mounted on the body generally over the engine for providing access to the engine from outside the body. An air inlet system associated with the cover member provides air from outside the body to the radiator. A plate attached to cover member directs air provided by the inlet system to the radiator in a manner such that the incoming ambient air does not scrub over the heated engine or the transmission.

  • Patent number: 4531936
    Abstract: A device and a method for the selective delivery of drugs or therapeutic agents to the heart. The device consists of a catheter which is introduced into the ascending aorta via the right brachial artery, the femoral artery, or directly. The balloon portion of the catheter is then inflated in the ascending aorta while introducing the drug or therapeutic agent through the distal opening and directly into the coronary arteries. Several doses of the drug or therapeutic agent may be given by delivery in coordination with timed inflation and deflation of the balloon during diastole of the heart. In addition, a two-balloon catheter may be utilized to enhance delivery of the drug or agent to the coronary arteries.

  • Patent number: 4531507
    Abstract: A charcoal lighter device having a tubular housing adapted to rest vertically on a support surface and a handle assembly positioned outside of and attached to the housing. A charcoal support grate fits in the housing and has a first edge pivoted in the housing and a second edge. A grate support finger is connected to the handle assembly and is positionable, by the movement of the handle assembly relative to the housing, between an extended grate support position and a grate release position. The second edge is positionable on the grate support finger such that the grate is in a generally horizontal charcoal support position spaced above the support surface when the grate support finger is in its grate support position, and the second edge pivots downwardly from said generally horizontal position to a charcoal dumping position when the grate support finger is subsequently moved to its grate release position, thereby safely dumping the lit charcoal into a barbecue grill positioned beneath it.

  • Patent number: 4522242
    Abstract: A log debarker of the hollow-head type having a rotor journaled in a stator for rotation about a longitudinal axis of the rotor. A plurality of debarking tools are attached to the rotor for debarking a log being moved axially through the rotating rotor. Three independently and hydraulically-powered infeed spiked rollers are positioned on the infeed end of the stator for feeding logs into the rotor and three independently and hydraulically-powered outfeed spiked rollers are positioned on the outfeed end. The rollers are powered at differing rotational speeds to accommodate logs of uneven surfaces. An air-operated tensioning system including a quick release valve adjusts the position of the infeed and the outfeed rollers urging them towards the longitudinal axis and automatically jogs the rollers open when they are unable to mount a log. A lubricating system having lubricant filtering and flow control capabilities lubricate and flushes the bearings for the rotating rotor.
