  • Patent number: 3988979
    Abstract: A refuse compactor includes a refuse storage body, a compaction panel movable within the storage body to give refuse within said body an initial pack and a stuffer panel movable within said body to provide the refuse with a secondary pack.The stuffer panel may apply a higher packing pressure to the refuse than the compaction panel.The secondary pack applied to refuse by the stuffer panel has an upward component of movement with a greater upward inclination than the packing force applied to the refuse through movement of the compaction panel thereby offsets the gravitational effect of increased densification of refuse in the lower portion of the refuse storage body.First and second hydraulic motor means are respectively connected to the compaction panel and the stuffer panel.

  • Patent number: 3973744
    Abstract: A system for the emergency debarkation of personnel from an aircraft includes a first container member mounted to the door of the aircraft and a second container member hingeably mounted on the first container member to form a container for an inflatable raft or slide. A first latch assembly attached to the first container member and a second latch assembly attached to the second container member cooperate to secure the container when the container is closed. The second latch assembly includes first and second latch arms pivotal on the second container member between a first position in engaging relationship with the first latch assembly and a second position in disengaging relationship with the first latch assembly. Locking members cooperate with the latch arms for positively locking the second latch assembly in the first position to inhibit opening of the container.

  • Patent number: 3969232
    Abstract: A bearing liner for attachment to a substrate comprising a first wear resistant layer and a second wear resistant layer joined to the first wear resistant layer. The second wear resistant layer serves to increase the useful life of the bearing liner. In addition, the second wear resistant layer serves as a compliant layer for receiving any projections in the substrate so that the tendency of any such projections to cause local protrusions of the wear surface of the first wear resistant layer is reduced.

  • Patent number: 3950047
    Abstract: A bearing material comprising a plurality of frangible capsules, oil or grease in the capsules, and a body. The capsules are distributed in the body and the body at least partially defines a wear surface for the bearing material.

  • Patent number: 3942601
    Abstract: A vehicle having a particular area in proximity thereto which is dangerous to personnel when the vehicle is performing a particular function is combined with a personnel detection means mounted on the vehicle and having characteristics for providing an electrical output signal in response to the presence of a person in the particular area. Apparatus associated with the particular function is mounted on the vehicle and responsive to the output signal of the personnel detection means to inhibit the particular function and reduce the danger to the person in the particular area.

  • Patent number: 3940006
    Abstract: A refuse collection apparatus in which a packing panel having a curved packing surface is moved through a hopper. The hopper may include a vertically inclined forward packing surface so that refuse is packed between the curved packing surface and the vertically inclined forward packing surface of the hopper. The hopper may include a straight rearward wall portion with the packing panel having a narrowed lower edge. During its movement into the hopper, the packing panel may be moved so that its narrowed lower edge is in contiguous relation to the straight rearward wall portion of the hopper. The packing panel may include one or more upstanding ribs on its curved packing surface which provide a reduced area for application of high localized pressures to refuse contacted by a rib.

  • Patent number: 3934958
    Abstract: To provide support for a rotatable shaft, a bearing ball is fixed to the shaft and rotatably mounted within a bearing race. A low friction liner which is disposed between the wearing surfaces of the ball and the race includes a backing, which can be adhered to the wearing surface of the bearing race, and a layer of low friction material, which can be disposed to contact the bearing and thereby provide permanent lubrication between the bearing and the race. The backing can be paper impregnated with chopped, compressed fibers such as wood or rice to provide the liner with a substantially linear stress-strain characteristic similar to that of metals. The paper backing reduces the deflection of the liner in response to compressive stresses so that the accuracy of movement of the bearing within the race is increased significantly. The layer of low friction material may be formed from an intimate mixture of an adhesive and small particles of a low friction material.

  • Patent number: RE28717
    Abstract: An apparatus and method for operating an auxiliary hydraulic load at low noise levels. A pump having a capacity which is sufficiently large to supply the load with the necessary volume of hydraulic fluid at relatively low pump speeds is driven by an engine operating at a speed near its idling speed. Throttle control means control the fuel supply to the engine at a level sufficient to drive the pump while maintaining the engine speed near its idling speed. When the engine speed is increased to a predetermined level in excess of its idling speed, means are provided to maintain the output from the pump at or below a predetermined flow rate to not overload the pump means or the auxiliary load. The pump may include a variable displacement pump or a plurality of fixed displacement pumps with means to vary the pump output in response to the pressure demand from the auxiliary load to maintain the torque input requirements for the pump below a predetermined level.
