Appl. No.:

6/159871

Inventors:

Richard E. Wells - La Habra CA

International Classification:

D0606

US Classification:

D 6 85

US Patent:

40170535, Apr 12, 1977

Filed:

Feb 6, 1974

Appl. No.:

5/440165

Inventors:

Richard E. Wells - Westminster CA
Victor E. Derval - Seal Beach CA
John D. Muchow - Cerritos CA

Assignee:

Willis Oil Tool Co. - Long Beach CA

International Classification:

F16K 31143

US Classification:

251 58

Abstract:

A shut-off valve in a fluid line closes by spring pressure and/or line pressure and incorporates a control chamber wherein pressurized control fluid acting on a piston opens the valve in opposition to the spring pressure and/or line pressure. A 3-way actuator pilot normally places the control fluid in communication with the control cylinder but when vented cuts off the control supply fluid and releases the pressurized control fluid from the control chamber to cause the shut-off valve to close by spring pressure and/or line pressure. A monitor pilot responsive to pressure changes in the fluid line incorporates a relief valve and opens the relief valve by cam action to vent the actuator pilot whenever the pressure in the fluid line makes a predetermined departure from a normal pressure range.

International Classification:

A47F 501

US Classification:

211184

Abstract:

A wire divider for installation on a shelf, between the front and rear rows of holes therein, which can be installed on a variety of shelves with slightly different spacings between their front and rear holes, utilizing a divider construction which enables low cost production and reliable installation. The divider includes a plurality of wires forming a gate, including a heavy outer wire extending in a closed path with overlapping ends extending parallel to one another, and a foot which slides along the parallel wire portions and has hooks for reception in the shelf holes.

International Classification:

F16K 31122
F16K 4104
F16K 4114

US Classification:

137315

Abstract:

Pressurized fluid is controlled by a reverse valve gate on a valve stem that extends through annular packing in a bore of a bonnet to a piston in an outer control chamber. Control fluid pressure moves the piston inward to open the valve against line pressure on the valve and/or spring pressure on the valve. In the absence of both line pressure and control pressure, the valve is closed by spring pressure. The control chamber construction permits quick replacement of control chamber seals. In the event of a fire, the control chamber seals disintegrate to release the control pressure and thus cause line pressure and/or spring pressure to close the valve. The valve stem packing may be conveniently expelled hydraulically for replacement. Various different control assemblies may be mounted interchangeably on the valve bonnet without disturbing the structure of the valve. An auxiliary control may be quickly mounted on the outer end of the control chamber to convert the shut-off valve to manual operation.

Inventors:

Richard E. Wells - Anaheim CA

Assignee:

Felbro, Inc. - Los Angeles CA

International Classification:

A47B 9618
A47F 500

US Classification:

186 57

Abstract:

The check-out counter has a front end merchandiser which has a fixed display rack forming part of the merchandiser. The fixed display rack has merchandise display devices thereon. A movable display rack is movably mounted with respect to the display rack. The movable display rack also has merchandise display devices thereon. The movable display rack and fixed display rack are preferably engaged by a track system which permits the movable display rack to move from a first position where it covers the fixed display rack to a second position where it uncovers the fixed display rack and blocks the check-out lane adjacent the merchandiser.

Willis Oil Tool Co. - Long Beach CA

International Classification:

F16K 1700
F15B 1301

US Classification:

13762566

Abstract:

A shut-off valve in a fluid line closes by spring pressure and incorporates a control chamber wherein pressurized control fluid acting on a piston opens the valve in opposition to the spring pressure. A control system for the shut-off valve comprises a 3-way actuator pilot of the present invention in cooperation with a monitor pilot. The actuator pilot has a valve spool and four ports, namely, a supply port connected to a source of pressurized control fluid, a pilot port connected to the monitor pilot, a control port connected to the control cylinder of the shut-off valve, and an exhaust port for venting the control chamber of the shut-off valve. When the control system is in service and the monitor pilot senses an undue change in the pressure in the fluid line, the monitor pilot vents the actuator pilot to shift the valve spool therein to cut off the control fluid from the control port and simultaneously to place the control port in communication with the exhaust port to cause the shut-off valve to close.
