  • Publication number: 20200149622
    Abstract: An electric drive for a transmission having a housing, a pump drive, and a primary sump configured to hold oil and operatively connected to a vehicle engine. The electric drive includes an oil-cooled electric generator electrically connected to an oil-cooled electric motor by an inverter. The electric generator includes a generator oil output operatively connected to and configured to deliver a flow of oil to a secondary sump located in the housing. The electric motor includes a motor oil output operatively connected to and configured to deliver a flow to the secondary sump. The secondary sump is separate from the primary sump, wherein the oil from the secondary sump is pumped back into the lubrication circuit of the transmission. The secondary sump includes a feature to allow overflow to drain to the primary sump.

  • Patent number: 5088615
    Abstract: The present invention provides an apparatus for containing goods. A bail member is connected to a pail in such a manner that the pail and the pail member are able to withstand a centrifugally directed impact upon the bail member. A contact portion of the bail member substantially contacts a cross support member of the pail in response to such an impact. Additonally, the pails are designed to be stacked within one another. The structure is such that the bail members do not catch on the ridges or rims of lower pails in the stack.

  • Patent number: 5062952
    Abstract: Apparatus is disclosed for filtering melted plastic used in an injection molding system. The apparatus consists of a housing having an inlet and outlet with a cylindrical inner chamber disposed in alignment therebetween, and a tubular filter element threadably mounted in the internal housing. To avoid loosening of the filter element, a plurality of spiral surfaces are formed in the filter element that are exposed to the pressurized flow of melted plastic, generating a resultant force that tends to screw the filter element tighter onto its threaded mount. The threaded mount is at the inlet end of the tubular element, causing it to extend in cantilever fashion axially into the internal chamber and toward the outlet. This creates an annular discharge passage around the filter element that is unobstructed, permitting the filtered plastic to converge smoothly into the outlet.

  • Patent number: 4755290
    Abstract: Apparatus for continuously filtering a flow of melted plastic which includes means for purging the filter without interrupting continuous operation. A filter assembly consists of a trap plate and breaker plate between which filters are disposed. The trap and breaker plates each defines triangularly shaped openings diposed in a circular array, each of which is subdivided into smaller passages for filtering larger contaminants. Individual filters also of triangular configuration are sandwiched between registering openings between the trap and breaker plates, each filter consisting of a fine and coarse screen. A collector head is rotatably disposed for selective registration with each of the openings of the trap plate, and an indexing mechanism is included for stepping the collector head for stationary registration with each opening. The collector head communicates with a contaminant discharge passage that is open and closed in timed sequence with movement of the collector head.

  • Patent number: 4486304
    Abstract: Apparatus is disclosed for continuously filtering a flow of melted plastic which includes a mechanism for purging the filter without interrupting continuous operation. A filter screen is disposed in a circular chamber within the filter housing. A collector plate including a plurality of radially oriented, triangularly shaped passages is disposed on the upstream side of the filter screen, defining triangular pockets for collecting contaminants that cannot pass through the filter screen. A collector head is rotatably disposed for selective registration with the collector pockets, and an indexing mechanism is included for sequentially stepping the collector head around the collector plate for momentary registration with each collector pocket. The collector head communicates with a contaminant discharge passage that is opened and closed in timed sequence with movement of the collector head.

  • Patent number: 4362132
    Abstract: A two-cycle engine is disclosed which conventionally includes a piston that reciprocates between a closed combustion chamber and crankcase. The piston reciprocates through a connecting rod that is eccentrically connected to the crank discs of a crankshaft. The crankcase is partially circular in configuration, and the crankdiscs conform in shape to the crankcase. Each crank disc has an annular recess or pocket extending around its periphery for approximately 180.degree. and in opposition to the eccentric point of connection of the connecting rod. The pockets cyclically communicate with a fuel inlet port and carburetor, both of which are positioned below the crankshaft rotational axis on the downstroke side of the crankcase. Fuel transfer passages between the crankcase and combustion chamber are positioned to receive the fuel charge from each recess as it is thrown tangentially upward with rotation of the crank discs.

  • Patent number: 4299707
    Abstract: The disclosure is directed to apparatus for filtering a flow of melted plastic prior to use in an injection molding machine. The apparatus includes a cylindrical filter screen disposed in a cylindrical chamber to define an inner inlet chamber and outer outlet chamber. The incoming plastic enters the interior of the filter screen through an axial passage formed in the screen side wall. The material is thereafter forced radially outward through small filtration openings formed through the screen side wall, leaving filtered material and contaminants at the inner wall. Purging or cleaning of the filter screen is effected by a reciprocating shaft that passes through the cylindrical filter screen and partly defines the inner chamber. The shaft carries an imperforate cylindrical sleeve which slides axially through the inner chamber, wiping the inner cylindrical surface of the filter screen as it goes.

  • Patent number: 4054273
    Abstract: The disclosure is directed to dispersion apparatus for use with injection molding systems for thoroughly mixing hot melted plastic with coloring or other additives before injection into a mold. Dispersion is accomplished by passing the hot melted plastic through a chamber in which a plurality of smooth, spherical bodies are disposed. Each of the spherical bodies is formed with a plurality of peripheral grooves which are orthogonal and generally lie within planes passing through diameters of the body.

  • Patent number: 4021515
    Abstract: Plastic injection molding apparatus consisting of two mold sections which define a mold cavity therebetween and are relatively movable to permit formation and removal of an article through the injection of hot melted plastic under high pressure. A plurality of coring pins are employed in conjunction with the mold sections to create voids of desired configuration in the molded article. Means are included to sense the pressure of the hot melted plastic as it enters the apparatus, and to actuate the coring pins into position within the mold cavity to create the desired voids. The coring pins also sense pressure within the mold cavity to achieve a balanced, self-adjusting operation.

  • Patent number: 3990179
    Abstract: A pot for plants primarily used for a hanging pot including at least two interlocking, stacked sections, the lower of which has a plurality of spaced, upwardly open, downwardly extending slots or notches defined in its upper edge of size so that plant stems and branches in the lower section can be laid through the openings with the upper section of the pot removed. Then the upper section can be placed on the lower section to hold the stems in position extending through the slots in the side wall of the finished pot.
