A pressure transmitting device is disclosed having a member which defines a passage for the transmission of fluid pressure and a diaphragm associated with the passage defining member. There is also provided an annular securing member for securing said passage-defining member directly or indirectly to an apparatus containing fluid whose pressure is to be measured in such manner that the pressure of said fluid is applied to said diaphragm. The diaphragm is sealingly secured directly to the passage-defining member, and the securing member is detachably engageable over the said passage-defining member to secure the latter to fluid-containing apparatus.

Pressure coupling mechanism in a pressure monitoring assembly |

Rene G. Lamadrid |
The pressure monitoring assembly monitors changes in pressure of a fluid passing through the assembly. This is accomplished by passing a liquid through a pressure transfer device having first and second chambers therein separated by a flexible diaphragm. The first chamber has air therein and pressure changes are transmitted across the diaphragm from the second chamber through which the liquid flows. The assembly further includes a pressure transducer and a pressure coupling mechanism for coupling the pressure transfer device to the pressure transducer. The pressure coupling mechanism includes a body having a cylindrical chamber and a piston positioned for movement therein with a piston shaft protruding from a coupling end of the body. The shaft is biased outward from the coupling end of the body by a spring. The coupling end has an O ring seal which forms a seal with the pressure transfer device around an orifice in a wall of the second chamber when the pressure coupling mechanism is mounted to the pressure transfer device. The piston shaft has a through-bore to the cylindrical chamber so that air is trapped in an air passageway comprising the first chamber, the through-bore and the cylindrical chamber. As the pressure transfer device is latched to the pressure coupling mechanism, the shaft and piston are pushed against the spring toward the pressure transducer which is mounted to the body at one end of the cylindrical chamber thereby compressing the trapped air in the air passageway. |

In accordance with the present invention, a pressure indicator is mounted upon a railway car and is in communication with an opening into the pressure chamber of the car. The car may be, for example, a pressurized hopper car or a pressurized tank car. The indicator comprises a fixed assembly having a resilient member so engaging said fixed assembly that the resilient member may react against the fixed assembly. A movable assembly is provided, at least a portion of which is used to indicate the pressure in the chamber. A flexible diaphragm is provided in the indicator, preferably a rolling diaphragm, which is affixed to the fixed assembly and the movable assembly and enables the pressure applied to the indicator to be applied to the movable assembly against the bias of the resilient member and permit at least a portion of the movable assembly to indicate the pressure range in the tank. Preferably the indicating portion is color coded. |

A manometer is provided for metering samples of fluid flowing in devices wherein particle concentration in the fluid is being counted or measured. Such devices include particle counters for determining blood cell concentration in body fluid. The device includes low permeable stretchable diaphragms in the device connections for containing the mercury therein, and a slide valve in the vent connection to restrict the movement of the mercury during storage or shipment. The arrangement herein includes, also, a one-way valve downstream of the "stop" point to stop flow substantially immediately upon the cessation of the measurement interval to reduce unwanted airflow to the counting aperture. A start and stop arrangement in the mercury flow path for causing the leading edge of the mercury meniscus at the axis thereof to engage the electrode contacts includes simple wire tips extending into the mercury flow path to the axis thereof for engaging the axis of the mercury meniscus. A preset fixed sample volume metering chamber is provided which eliminates the need for calibration. |

SCHIJF J |
A pressure gauge for extrusion and injection moulding machines, in which a push rod connects a membrane at one end and a displacement meter at the other end of the casing. The usual thermal sensitivity of this kind of pressure gauges has been suppressed by the use of a hollow, thin-walled push rod that fits in the casing with a narrow clearance.

GARCEA G |
Device for measuring absolute pressures, of the pliable diaphragm type which cooperates with a capsule having rigid walls and containing the diaphragm. In the initial assembly stage, the diaphragm completely mates with the surface of either rigid wall of the capsule, so that virtually no air is sealed therebetween. On completion of the assembly, a preload is imparted to the diaphragm by means of an externally mounted spring, so that a vacuum is created between the diaphragm and the rigid wall confronting the diaphragm with the device being adapted not only to measure absolute pressures, but also to control servo devices in response thereto.
