  • Patent number: 4317327
    Abstract: A dethatching unit is mounted for attachment to the front end of a self-propelled lawn mower, for example, so that the dethatching unit is pushed by the lawn mower and thatches the ground prior to mowing thereof. The dethatching unit includes a frame having a caster wheel at its forward end and arms at its rear end for attaching to the mower. The wheel and the arms cooperate so that tines, which are mounted in two rows on the frame, do not carry any of the weight of the unit so that the bottom tip of each of the tines is slightly spaced from the ground in its rest position. Each of the tines in each of the rows is offset from each of the tines in the other row. Forward motion of the dethatching unit causes the bottom tip of each of the tines to deflect rearwardly and downwardly as it comes in contact with grass. In their deflected positions, the bottom tips of the tines contact the thatch layer to tear it loose from the soil and ultimately flip the thatched material to fall on the ground.

The booster is therefore hydraulic pressure suspended so that the hydraulic pump of the system need not be operating to maintain this pressure while the booster is inactive. An accumulator is also charged by this pressure to provide power brake booster operation for several booster actuations without recharging by the pump. When the pump is operating, a pilot valve which is sensitive to a drop in booster operating pressure will control charging or recharging the accumulator and booster from the pressure generated by the pump to maintain a desired charge pressure. A pressure relief valve will also prevent overcharging of the accumulator and booster. A check valve prevents loss of booster operating pressure toward the pump outlet if the pump pressure falls below the charged pressure.

  • Patent number: 4317334
    Abstract: A refrigeration system in which compressors are mounted in one compartment of the housing and condensers and receivers are mounted in an adjacent compartment. Ambient cooling air flows first into the compressor compartment, then into the condenser compartment, and then to the atmosphere. Parallel flow paths from the compressor compartment to the condenser compartment are provided--one flowing the air over the condensers, the other bypassing the condensers, before being expelled. The bypass has a movable flapper valve controlled by the ambient air temperature which causes the ambient air to bypass when its temperature drops below a given point. A shroud encloses the receivers and has a fan-driven heater controlled by the same thermal sensor that controls the flapper valve.

  • Patent number: 4317336
    Abstract: An electron discharge tube evaporation cooling system in which part of a tube to be cooled is immersed in coolant in a boiler (15), the cooling system further comprising a condenser (18) for vapor generated in the boiler (15), and a coolant reservoir (11). The flow of vapor from the boiler (15) to the condenser (18) experiences resistance in the interconnecting pipe (17), producing in the boiler (15) a back pressure dependent on the dimensions of the pipe (17). In order that a desired level (40) of coolant in the boiler (15) can be obtained for a range of back pressures, the coolant is supplied to the boiler via an overflow system (16) having an adjustable overflow level. The overflow system (16) comprises a chamber (31) open to atmosphere at the top (34) and having at the bottom (33) an opening (36) through which an overflow tube (35) passes.

  • Patent number: 4317338
    Abstract: A universal joint for connecting a pair of elongated members is disclosed. The joint provides for transmission of torque between the pair of members when the pair of members are oriented at various angles relative to each other. One of the members terminates in a cavity, or housing, which is substantially cylindrical. The other member extends into the cavity and a pair of sockets cooperate with the other member to secure the latter within the cavity. The pair of sockets include outer surfaces which substantially match with the cylindrical cavity surface to enable the pair of sockets to rotate in a plane relative to the one member. The pair of sockets include projections which are received in an opening on the other member to enable the other member to pivot relative to the pair of sockets and the one member in substantially perpendicular plane.
