  • Patent number: RE32803
    Abstract: A hydraulic circuit is disclosed for activating a clutch as well as a throttle valve which is used in the circuit. The hydraulic circuit includes a hydraulic actuator which is connected to a source of pressurized fluid to alternatively activate the clutch. Connected between the source of pressurized fluid in the actuator is a control valve and a pressure-responsive throttle valve. The control valve is basically an on/off valve which controls the flow of fluid to the clutch actuator or from the clutch actuator to a reservoir. The throttle valve, on the other hand, is arranged in series with the control valve and is responsive to fluid pressure on its downstream side to cause increased throttling of the fluid as the fluid pressure to the actuator increases. Such a circuit is beneficial in preventing the clutch from snatching as it is being engaged.

  • Patent number: 4791688
    Abstract: A jet pump macerator pump sewage handling system which provides a unique waste control system for use in mobile units such as passenger trains and ships in which multiple toilets are connected to a transfer manifold pipe which communicates with a non-clogging jet pump which is formed with a venturi and through which liquid material is driven by a macerator pump. Waste material from the toilets is drawn by the jet pump through the transfer manifold pipe and discharged into the retention tank. The macerator pump withdraws material from the retention tank, grinds it and discharges it back into the retention tank. The macerator pump has a self-cleaning feature in that it reverses and cleans itself whenever a loss in discharge pressure due to excessive solids loading is sensed. The transfer manifold pipe is virtually free from clogging due to the action of an air induction valve which keeps waste material in the manifold pipe moving without allowing it to accumulate.

  • Patent number: 4791697
    Abstract: A wiper arm for use with a highly curved windshield is designed so that the wiping pressure in the blade is substantially constant in spite of the deflections up and down to which the arm is subjected. The arm consists of two parts, a channel shaped main body cantilevered from the post of the wiper drive mechanism, and a slider bar that is free at its back end. As the arm deflects, the main body bends, creating a resistance force that adds to the wiping pressure in the blade, while the back end of the slider bar moves relative to the main body of the arm. A tension spring hooked between the back end of the slider bar and the vehicle pulls the arm toward the windshield, also adding to the wiping pressure. However, as the arm deflects up, the spring relaxes, so that the contribution of the spring to wiping pressure decreases concurrently with the contribution of the bending main body of the arm increasing. Therefore, the total wiping pressure remains more nearly constant.
