Appl. No.:

13/492143

Inventors:

Richard M. Larson - Des Plaines IL, US
David C. Rupp - Grayslake IL, US

Gerald A. Greca - Carleton MI, US

International Classification:

F16J 15/32

US Classification:

277549

Abstract:

A shaft seal assembly for establishing a liquid-tight seal between a steering knuckle and an axle shaft is provided. The shaft seal assembly includes an outer case and a first elastomeric member attached to one another. The elastomeric member has a castellated feature including a plurality of projections extending in a radially outward direction and separated from one another by a plurality of grooves. When the shaft seal assembly is installed in the steering knuckle, a cavity is presented between the steering knuckle and the first elastomeric member. Together, the grooves and cavity allow air to flow from a hub on one side of the seal assembly to a vacuum port in the steering knuckle. The cavity extends circumferentially around the seal assembly, and thus, air flow from the hub to the vacuum port is not dependent upon the orientation of the seal assembly relative to the steering knuckle.

International Classification:

A01N 1/02

US Classification:

435 12, 4352841

Abstract:

A temperature sensor for monitoring an organ or tissue is configured to measure a temperature inside of a container configured to contain the organ or tissue. The temperature sensor is disposed exterior to the organ container and the temperature sensor is a non-contact temperature sensor. The temperature sensor may be part of an apparatus for perfusing, transporting, and/or storing an organ or tissue. A coolant container may have an aperture through which the temperature sensor measures a temperature of at least one of the organ or tissue or a perfusate fluid surrounding the organ or tissue. The temperature sensor is preferably an infrared temperature sensor. Multiple temperature sensors may be provided that measure the temperature organ or tissue or perfusate fluid surrounding the organ or tissue, for example in case one of the temperature sensors fails.

International Classification:

G01L 500

US Classification:

73862381

Abstract:

An apparatus and method for testing a switch having an actuating plunger, the switch undergoing a switch event in response to the actuation of the actuating plunger includes a switch nest and clamp assembly for holding the switch at a precise and predetermined location and a motor driven plunger actuator for applying force to the plunger thereby to actuate the switch. The switch test station further includes a pressure sensor coupled to the plunger actuator which measures the force being applied to the plunger during switch actuation. An electrical sensor couples to the switch nest and measures the electrical characteristics of the switch while a microcomputer responsive to the pressure sensor and the electrical sensor determines the mechanical displacement of the actuating plunger at a switch event.

International Classification:

A01N 1/02

Abstract:

A method of perfusing an organ or tissue includes perfusing the organ or tissue with a perfusion apparatus; detecting a condition representing at least one of an attitude of the perfusion apparatus or at least one shock experienced by the perfusion apparatus; and altering perfusion based upon the detected condition and/or recording the detected condition.

International Classification:

B29C 41/52

US Classification:

264 401

Abstract:

Processes for making press-in-place (PIP) gaskets. Representative components with gasket cavities (grooves) are prepared and the cavities are filled with a curable molding material. Once the molded gaskets are hardened, they are removed from the cavities. The molded sample gaskets are then measured, preferably by a laser scanner, and drawings are prepared based on the measurement data. Appropriate tooling is then created and the gaskets are produced.
