  • Patent number: 4431046
    Abstract: A low pressure casting process using a furnace of the channel-type induction for heating, the furnace power being automatically controlled by direct temperature measuring of the molten metal bath according to the desired casting temperature. The feeding chamber of the furnace is of pressure-type and has a protective gas with a slight over-pressure. The furnace is filled via a syphon-shaped feeding chamber whereby metal is inserted below the level of molten metal in the feeding chamber and the protective gas therein is not affected. An operator starts the casting process whereby a casting mold is closed and assumes a casting position over the casting nozzle from the furnace and metal is forced into the mold. The mold, one of several on a carousel is moved to a station wherein the casting is automatically discharged to a conveyor belt. The mold next moves to an immersion bath where it is treated, and then to a preparation station wherein it may be cleaned and cores inserted.

  • Patent number: 4416582
    Abstract: A multi-stage turbine has an inflow disc pack that directs motivating fluid to an outflow disc pack on the same shaft. The packs are fitted to rotate between plates that web a turbine casing interior and fluid entry into the casing to the inflow pack is via nozzles in a ring assembly fixed to the casing. Each disc pack is made up by spaced apart discs with fences that guide the motivating fluid first through the inflow pack and then the outflow pack. A central passageway in the packs and adjacent the shaft communicates fluid inflow to outflow. Fluid exhaust is through exits at the casing bottom. In one version, the disc packs are conical and when seen from the side, the packs with webbed plates are X configured in section. In another version, the inflow pack is flat, the outflow pack conical and the casing of both versions are configured to provide low losses and maximum strength. The nozzles can be convergent-divergent in a plenum located adjacent the inflow pack circumference.

  • Patent number: 4412587
    Abstract: A soil working machine has a working member with element blades and a scraping member that releases clods cut out by the working member so that the clods drop to the ground. Both of the members can be positively driven in the same direction about horizontal axes, but the scraping member can also be rotated by contact with the ground. Preferably, the blades are secured to support discs and extend axially of the working member. Scraping elements on arms of the scraping member project between the blades of adjacent support discs and have vanes which also extend almost axially. During rotation, the vanes are moved to intersect the paths of the blades and to remove the clods. Other forms of scraping members are described. The scraping member ensures that soil is wiped from the blades, to avoiding clogging of the working member and a consequent increased power requirement. Also, the cut clods are preferably replaced upside down by the action of the members.

  • Patent number: 4312537
    Abstract: A vehicle seat includes a subframe arranged to be secured to the vehicle or and an upper frame mounted on the subframe by four pivotal levers to form two pairs of parallelogram linkages and so constrain movement of the upper frame relative to the lower frame along an arcuate path.A pair of mounting plates carrying a back rest are pivotally secured to opposite sides of the upper frame. A pair of control levers couple the mounting plates to respective levers in a manner such that when the mounting plates are pivoted by tilting the back rest forward into a horizontal attitude, the upper frame is caused to move along its arcuate path and so draw the back rest forward to allow greater access to the area behind the back rest.

  • Patent number: 4304313
    Abstract: An agricultural type tractor with lifting devices on the front, rear and both sides for agricultural implements. Each pair of rear drivable wheels which are in tandem pivot about a common axle and each pivotable pair of such wheels is driven by a separate hydraulic motor, with each motor, however, connected to a common control whereby the velocity of the wheels on one side can be increased while the velocity of those on the other is decreased for steering around curves and the like. The arrangement also provides a hydraulically lockable differential to avoid the spinning of one set of the drivable wheels while the other set does not move due to an obstruction or the like. Outboard of each set of drivable wheels is a rotatable supporting element which is mounted from the tractor's frame so as to be displaceable outwardly and upwardly relative to the adjacent 0010 set of drivable wheels. Each supporting element has two wheel members which receive an endless chain tread.

  • Patent number: 4291946
    Abstract: A tractor which is towing two agricultural implements extending transversely relative to the longitudinal axis of the tractor and having a width which is substantially greater than that of the tractor's width, the two implements being coupled to the tractor in tandem. The interior of the tractor's cab has a convex (as seen by the driver) mirror which extends almost completely across the interior of the glassed-in cab of the tractor so as not to block the driver's forward vision, whereby the driver can observe in the mirror both implements across their entire widths as well as the device for coupling both implements to the tractor. In a modification, the convex mirror is of less width (about one-half of the width of the cab) and is flanked by further mirrors on each side which reflect from still further mirrors mounted on the overhead of the cab to provide an increased lateral area which is within the vision of the driver through the mirrors.
