Filed:

May 16, 2003

Appl. No.:

10/439727

Inventors:

Wayne Davis - Barrington IL, US
Paul Ribich - Lake Villa IL, US
Dan Harvey - Lake Geneva WA, US
Nawaz Kasam - Hanover Park IL, US

Assignee:

Watlow Electric Manufacturing Company - St Louis MO

International Classification:

H05B 3/06

US Classification:

219536, 219548, 219552, 374208, 338 25, 338 26

Abstract:

An end seal for a temperature sensing probe. Electrical interface wiring is passed through a restraining element and is operatively coupled to a temperature sensing element or heater element mounted in the sheath. The sheath is formed around the restraining element in a shape that provides a net force inward as temperature variations expand and contract the restraining element.

International Classification:

F15B 1522

US Classification:

91395

Abstract:

An expandable cushion plunger for use with a fluid pressure driven piston and cylinder device includes a cushion sleeve mounted on a piston rod in floating relation thereto, and having a skirt, the interior of which is exposed to the cushioning fluid within the cylinder. As the piston nears the end of its stroke, the sleeve begins to enter a fluid exit port, trapping fluid between the piston and the cylinder head, which will slow and cushion the piston travel as it approaches the cylinder head. As the sleeve continues to enter the fluid exit port, the pressure of the trapped fluid increases due to the smaller size of the annular orifice between the sleeve and the port as compared with the port size. The cushion sleeve may expand under influence of increased pressure, further restricting the flow of pressurized fluid through the annular orifice to provide smooth deceleration of the piston as it reaches the end of its stroke and comes to rest against the cylinder head without undesirable impact.

International Classification:

US Classification:

Abstract:

A retaining ring locking device for preventing longitudinal relative movement of a shaft within a bore utilizes a flat or wire retaining ring. A groove is machined on the shaft as well as the bore and an access window is provided on either the shaft or the device containing the bore. The access window extends longitudinally from and beside the ring receiving groove formed by the alignment of the shaft and bore grooves to the exterior of the device and serves as the access point for threadable insertion of the retaining ring. The encapsulated design provides greater strength and eliminates the need for two separate retaining rings to prevent relative movement in two directions.
