Abstract: An oil pan assembly for an automotive vehicle is formed with an oil pan which is divided by a partition wall into a first and a second chamber. Oil is pumped by an oil pump from the first chamber into the engine of the vehicle through a pipe including an oil strainer. The partition wall is provided with a temperature responsive valve which closes when temperature of the oil is below a predetermined level to cut off flow communication between the second chamber and the first chamber. Thus, with the valve closed, all the oil going to the vehicle engine is drawn from the first chamber. When the temperature of the oil rises above a predetermined level, the temperature responsive valve opens thereby permitting oil circulation from the second chamber into the first chamber.

Abstract: A reliable efficient rotary valve apparatus for internal combustion engines, configured for ease of installation and maintenance. Rotating valve apparatus controls transfer of intake and exhaust gases between intake and exhaust manifolds respectively of an internal combustion engine and the respective combustion cylinders thereof. Intake and exhaust portions of the rotary valve assembly are isolated by simple seal members. Activating means, responsive to rotation of the rotatable valve member, create positive fluid-flow transfer of gaseous currents through the rotating valve member. Spring biased, pressure equalizing plunger seal apparatus increases reliability and longevity of use of the rotary valve apparatus and maintains proper seals for fluid-flow passage between the rotating valve member and individual compression cylinders of the engine.

Abstract: Normal steady venous return flow in a limb is rendered intermittent by means to occlude the venous system in the limb for a first period of time while permitting pulsatile arterial inflow to the limb. Means to release the venous system for a second period of time allows a rapid exponentially decreasing outflow of the blood that was pooled in the venous system during the first period. The exponentially decreasing outflow may be detected by a flowmeter responsive only to pulsatile flow. The flowmeter may also detect unwanted heart-synchronized signals. The latter may be cancelled from the venous blood flow signal by detecting and storing heart-synchronized signals during at least a part of the first period (of zero venous flow) and subtracting the stored signals from signals detected during the second period.

Calibration of the balloon monitor provides means for accurately observing both the volume and pressure of air in the system. Therefore, visual inspection of the balloon monitor indicates by reason of the calibration the prevailing level of pressure in the patient's endotracheal cuff.

Abstract: A system for extending the lifetime of an implantable cardiac pacer of the type having an internal primary battery power source includes an external energy transmitting source for selectively externally powering the pacer in order to reduce consumption of the internal battery power.

Abstract: A manual fluid pressure controller has a handle with integral cam which mates with a non-rotating cam follower. Rotation of the handle causes displacement of the cam follower which transmits a force through a metering spring to a metering piston. The metering piston actuates a combined inlet-exhaust valve to admit or exhaust fluid pressure to its one face until the spring force on its other side is balanced. The fluid pressure at the face of the metering piston is connected to the load whose pressure it is desired to control. A cam stop, integral with the cam follower cooperates with a matching stop on the handle to limit handle travel.

A vented airspace is also provided between the drinking water pipe and the housing.

Abstract: A faucet valve for kitchen sinks, bathroom washbasins and like applications, said faucet valve being adapted to be made of molded plastics, having relatively few operative parts, and designed to minimize the stresses of assembly and use. The invention has two principal features: the first is the use of a ratchet interlock between the bonnet of the valve and the cover plate of the sink or washbasin, said interlock being oriented to allow the bonnet to be rotated in one direction relative to the valve body in order to thread the bonnet into engagement with the valve body, and to prevent the bonnet from rotating in the opposite direction relative to the valve body when the valve is in use; and the second is the use of a self-centering valve closure member in the form of a spherical ball mounted within a spherical socket with sufficient clearance between them to enable the ball to float relative to the valve seat.

Abstract: A slam-shut valve provides overpressure protection in a pipeline in the event of regulator failure. The slam-shut valve is normally held latched in the open position. Overpressure or failure of the regulator will automatically trigger operation of the slam-shut valve to close the same and prevent further passage of the gas through the pipeline. The slam-shut valve is manually reset to the open position once it has been triggered closed.The invention includes mounting the closing spring upon the lever in loaded position. The latch lever forms a subassembly, which in turn, is installed in the housing of the slam-shut valve to operatively interconnect the latch and release mechanisms and the reset mechanism. Subsequent to installing the lever, on end of the loaded closing spring is released from the lever to snap into position against the adjacent housing wall to bias the lever to the closed position. However, closing is normally prevented by the latch which releasably holds the lever in the open position.

The engine also drives wheels of a cart-like carriage of the line mover through reversible one-way clutches.

Abstract: In order to obtain very close control of the flowrate of a fluid through a conduit against a predetermined desired flowrate, a pulse generator is employed to produce pulses at a frequency representing the desired flowrate, and a flowmeter issues similar pulses representing the actual flowrate. First and second difference pulse streams are digitally derived to represent the difference by which the actual flowrate either exceeds or falls short of the desired flowrate, and these difference pulse streams are applied, respectively, to count down and count up inputs to an up/down counter. The instantaneous count held within the up/down counter is translated to an analog signal by a digital-to-analog converter, and the analog signal is applied to the input of a two-wire transmitter. The two-wire transmitter drives a valve-actuating motor, such as a d-c torquemotor, to correct the valve position as necessary to obtain and maintain the desired flowrate.

Abstract: A bi-directional fluid flow control valve is provided with a spool-like valve body with a circumferential relief in its periphery bounded by a seal disk and by a reduced-diameter portion of the valve body, with a substantially tubular, elastic membrane stretched over the aforementioned portion and the seal disk, spanning the relieved portion. A flow channel penetrates the valve body centrally from the end closest to the reduced-diameter portion, and communicates with said relief via radial passages. Pressure differentials in either sense across the tubular membrane distort the membrane in such a manner that a flow passage is opened across the valve. When the pressure in the relieved groove is greater than on the outside of the membrane, the latter lifts from the seal disk. When the external pressure is greater, the membrane collapses into the relief groove, allowing flow through channels milled in the inner face of the seal disk.

The device can be arranged advantageously, at the input of a reaction chamber with a catalytic charge, in order to distribute the reactants over the cross section of the catalytic chamber.

Abstract: The present invention relates to a device for accurately controlling the splitting and/or proportionalizing of a flowing liquid into two preset flows. The device is capable of maintaining the desired preset quantitative relationship between incoming and outgoing flows regardless of the flow characteristics of the incoming liquid.

The collector is divided into two collector chambers by partitions located on opposite sides of a central column with the flow distributor connected to a shaft rotatably mounted within the central column so as to place one of the partitions in the flow path of the liquid emerging from the distributor, thereby splitting that flow.
