| 21 | SYRINGE BARREL WIPER FOR LIQUID DISPENSING | US12048916 | 2008-03-14 | US20080223209A1 | 2008-09-18 | Harry F. Slater |
| A syringe for syringe pumps or like instruments is disclosed, having a modified plunger disposed with a barrel wiper for enhancing seal life of the syringe. The syringe comprises a cylindrical barrel that is slideably engaged to a plunger via a seal. The syringe barrel wiper provides for enhanced seal life by extended controlled lubrication to inhibit debris adherence and reduced seal friction by wiping the inside of the barrel to remove debris buildup and egress of debris. The wiper comprises a lubricant-permeated porous polymer material shaped as a cylindrical tubular member. | ||||||
| 22 | Gas meter counter unit with improved shaft lubrication | US36601 | 1993-03-24 | US5307902A | 1994-05-03 | Richard T. Herrmann; Albert B. Atkinson |
| In a meter counter assembly of a gas meter, a rotatable shaft of a gear train is journaled in a bore that extends through a support plate mounted in the housing of the counter. The plate is of a porus material, forming capillary passages for the transmission of lubricant therethroughout. A portion of the support plate extends into a lubricant reservoir in the housing. In use, lubricant migrates through the capillary passages to the bore from the reservoir for lubrication of the shaft. | ||||||

| A gear train in a counter unit of a rotary positive displacement gas meter includes loosely fitting tubular sleeves telescoped around rotatable shafts in the train. The sleeves are located between gears that are partially immersed in a lubricant reservoir contained within the counter unit and adjacent bearings and gears that are out of direct contact with the lubricant in the reservoir. During operation of the meter, oil from the reservoir flows through passages formed between the inside of each sleeve and the outside of the shaft upon which the sleeve is mounted so that the gears and the bearings in the counter unit are lubricated. | ||||||

| A meter is mounted inside a housing where the meter is designed for low pressure gas flow measurement and the housing is designed to withstand high pressure differentials. The meter itself includes a plurality of divided chambers and one chamber includes moving elements to measure the flow of gas between the inlet and the outlet. The moving elements inside the gas transmission chamber are supported in place in bearings mounted in dividing walls. Chambers on each side of the dividing walls which define the gas transmission chamber include oil slingers which dip into puddles of oil in the bottom of the chambers and fling a fan of oil upward to lubricate the bearings and other moving parts. | ||||||

| A turbine flowmeter comprises an impeller which has a rotary shaft rotatable together with the impeller and is provided within a flow passage through which a fluid to be measured flows, a pair of bearing members for axially supporting the rotary shaft, an oil accumulating part for holding a lubricating oil therein, and an oil supplying part for supplying the lubricating oil in the oil accomulating part in small quantities to at least one of the bearing members. The oil supplying part comprises a capilary member. | ||||||
| 26 | Procedure for lubricating the bearings in equipment comprising a plurality of oil-lubricated bearings | US515035 | 1983-07-18 | US4519247A | 1985-05-28 | Kalevi Horttonen |
| A procedure and means for lubricating the bearings in equipment comprising a plurality of oil-lubricated bearings (7). The oil is conducted to each bearing separately through a volumetric meter (4) which meters the oil quantity going to the bearing. The oil is conducted to a unit (14) comprising a plurality of volumetric meters (4), where it is distributed through a branching tube (2-3) comprised in the unit to each meter. A signal proportional to the flow passing through each meter can be conducted electrically further to a monitoring point. | ||||||
| 27 | Flow meter having a rotary body | US273146 | 1981-06-12 | US4393724A | 1983-07-19 | Karl-Heinz Werkmann; Wolfgang Sauerschell |
| The present invention relates to a flow meter, particularly for liquids, having an impeller wheel arranged in a vertical tubular measurement bore and acted on by a flow stream. The impeller wheel has a bearing shaft, the ends of which are rotatably mounted in axially and radially guiding bearings respectively. The impeller wheel has one or more vanes, the flow-on attack surfaces of which are inclined to the direction of oncoming flow of the stream. A sensor detects the rotary frequency of the impeller wheel. A movable wall subdivides a chamber into two chamber halves, one of which communicates with an inlet connection and the measurement bore upstream of the impeller and the other one of which communicates with an outlet connection and the measurement bore downstream of the impeller. In order, with such a flow meter, to make possible in simple manner and at low cost of manufacture a high precision of measurement over the entire measurement range, the bearing shaft is arranged with axial play between the bearings and the impeller wheel is acted on from below by the flow. In this connection, the attack surfaces are so inclined with respect to the direction of flow that the force component, directed in the approach direction, of the force exerted by the flow stream on the impeller wheel is equal to or greater than the weight of the impeller wheel. | ||||||

| The density of the fluid flowing through a tubular member may be measured by a device comprising a rotor assembly suspended within the tubular member, a fluid bearing medium for the rotor assembly shaft, independent fluid flow lines to each bearing chamber, and a scheme for detection of any difference between the upstream and downstream bearing fluid pressures. The rotor assembly reacts to fluid flow both by rotation and axial displacement; therefore concurrent measurements may be made of the velocity of blade rotation and also bearing pressure changes, where the pressure changes may be equated to the fluid momentum flux imparted to the rotor blades. From these parameters the flow velocity and density of the fluid may be deduced. | ||||||
