Magnetic Pressure Indicator With Sampling Ports
View pageUS Patent:
40261530, May 31, 1977
Filed:
Aug 8, 1975
Appl. No.:
5/602937
Inventors:
Bernard F. Silverwater - Plainview NY
Assignee:
Pall Corporation - Glen Cove NY
International Classification:
F17D 300
G01N 122
G01L 1912
G01N 122
G01L 1912
US Classification:
734215R
Abstract:
A magnetic differential pressure indicator is provided for detecting and indicating a pressure differential thereacross that is greater than a predetermined value in a fluid system. The sampling port permits withdrawal of fluid for examination without interference with operation of the indicator.
Temperature Responsive Bypass Filter Assembly
View pageUS Patent:
47832711, Nov 8, 1988
Filed:
Jun 27, 1986
Appl. No.:
6/879308
Inventors:
Bernard F. Silverwater - Plainview NY
Assignee:
Pall Corporation - Glen Cove NY
International Classification:
B01D 2710
US Classification:
210742
Abstract:
A filter assembly for removing particles from a fluid which comprises first and second filters, each having a porous filter medium. The mean pore diameter of the porous filter medium of the second filter is greater than the mean pore diameter of the porous filter medium of the first filter. The filter assembly further comprises structure for directing the fluid serially through the first filter and then through the second filter, a mechanism for sensing the temperature of the fluid, and a valve arranged in parallel with the first filter and serially with the second filter. The valve is coupled to the temperature-sensing mechanism so that at least a portion of the fluid is directed around the first filter in response to a predetermined fluid temperature. For example, in the illustrated embodiment, the fluid is directed around the first filter when the fluid temperature is below a predetermined value.
Automatic Pressurized Reservoir Bleed Valve
View pageUS Patent:
48134465, Mar 21, 1989
Filed:
Jan 29, 1988
Appl. No.:
7/150307
Inventors:
Bernard F. Silverwater - Plainview NY
Arkady Flikop - Brooklyn NY
Arkady Flikop - Brooklyn NY
Assignee:
Pall Corporation - Glen Cove NY
International Classification:
F16K 2400
US Classification:
137198
Abstract:
An automatic bleed valve for bleeding air from a pressurized liquid reservoir or, with reversal of principal elements, bleeding liquid from a compressed gas reservoir comprises a piston in a piston chamber located in a flow passage leading from the reservoir. A capillary passage is provided through the piston, and the piston is urged upstream by a resilient spring. An orifice is located in the fluid channel. A sealing element is provided at the downstream end of the piston chamber. Upon activation of the hydraulic system while air is being expelled from the reservoir, the resilient spring will retain the piston in the upstream position, allowing gas to be bled from the reservoir through the fluid passage in the piston. When liquid begins to flow from the reservoir, the pressure differential over the piston increases, causing the piston to move against the downstream end of the piston chamber and seal off the fluid channel and the hydraulic reservoir.
Pressure Indicating Device
View pageUS Patent:
46516700, Mar 24, 1987
Filed:
Sep 27, 1985
Appl. No.:
6/781222
Inventors:
Bernard Silverwater - Plainview NY
Assignee:
Pall Corporation - Glen Cove NY
International Classification:
G01L 1912
US Classification:
116268
Abstract:
A device for indicating differential pressures between first and second pressure sources comprising a housing with a bore and a piston member slidably disposed within the bore and dividing the bore into first and second chambers. The piston member includes a permanent magnet and the housing includes ducts for connecting the first pressure source to the first chamber and the second pressure source to the second chamber whereby the piston member is displaceably responsive to differences in pressure between the first and second pressure sources. The device further comprises indicators in cooperative arrangement with the piston member for indicating at least first and second predetermined differential pressure levels respectively corresponding to respective displacements of the piston member within the bore. The indicators are magnetically coupled to the piston permanent magnet such that they move from non-signalling to signalling positions in response to the respective displacements of the piston member.
Magnetic Pressure Indicator With Thermal Lockout
View pageUS Patent:
41729714, Oct 30, 1979
Filed:
Oct 30, 1978
Appl. No.:
5/956291
Inventors:
Bernard F. Silverwater - Plainview NY
Charles Grimm - Palm Harbor FL
Charles Grimm - Palm Harbor FL
Assignee:
Pall Corporation - Glen Cove NY
International Classification:
G01L 914
US Classification:
200 82E
Abstract:
A magnetic differential pressure indicator is provided for detecting and indicating a pressure differential thereacross that is greater than a predetermined value in a fluid system. A thermal lockout effective even at high internal fluid pressures prevents false actuation of the magnetic indicating means at low temperatures due to increased viscosity of the system fluid.
Device For Determining The Concentration Of Suspended Solid Contaminants In A Fluid
View pageUS Patent:
44689543, Sep 4, 1984
Filed:
Nov 22, 1982
Appl. No.:
6/443360
Inventors:
Robert Lanctot - St. Petersburg FL
Bernard F. Silverwater - Plainview NY
Bernard F. Silverwater - Plainview NY
Assignee:
Pall Corporation - Glen Cove NY
International Classification:
G01N 1506
US Classification:
73 61R
Abstract:
A device is provided for determining the density or concentration of solid contaminants suspended in a fluid, having an orifice or narrow passage through which the fluid carrying suspended solid contaminants is passed, and monitoring the rate of build-up of the contaminants at the orifice or narrow passage as a function of the density or concentration of the contaminants in the fluid.
Magnetic Pressure Indicator With Deactuator For Bimetallic Temperature-Sensitive Elements
View pageUS Patent:
42033845, May 20, 1980
Filed:
Aug 28, 1978
Appl. No.:
5/937669
Inventors:
Bernard F. Silverwater - Plainview NY
Assignee:
Pall Corporation - Glen Cove NY
International Classification:
G01L 716
US Classification:
116267
Abstract:
A magnetic differential pressure indicator is provided for detecting and indicating a pressure differential thereacross that is greater than a predetermined value in a fluid system, having a port that permits introduction or withdrawal of fluid for testing of operability under the predetermined pressure differential, and having a bimetallic element that prevents false actuation of the element at abnormal temperature, and a deactuator for the bimetallic element that permits such testing of the indicator via the port for operability even at such abnormal temperature.
