C01G045/02
H01M004/50

US Classification:

423605, 429224

Abstract:

Particulate MnO, having simultaneously a micropore surface area greater than 8. 0 m/g, desirably between about 8. 0 and 13 m/g and BET surface area of between about 20 and 31 m/g within the context of an MnOhaving a total intraparticle porosity of between about 0. 035 cm/g and 0. 06 cm/g produces enhanced performance when employed as cathode active material in an electrochemical cell, particularly an alkaline cell. The average pore radius of the meso and macro pores within the MnO(meso-macro pore radius) is desirably greater than 32 Angstrom.

Appl. No.:

11/411713

Inventors:

Thomas C. Richards - Libertyville IL, US

Assignee:

Illinois Tool Works, Inc. - Glenview IL

International Classification:

G08B 13/08

US Classification:

3405453, 340562

Abstract:

An electronic proximity switch employs two oscillators coupled through two electrical paths, one associated with an antenna serving as a proximity switch sensor. Absorption by an object near the antenna changes the coupling between the oscillators producing a dramatic phase shift that may be detected and used for switching purposes.

H01M 4/64

US Classification:

429234, 429162, 429206

Abstract:

A wafer alkaline cell of a laminar structure is disclosed. The cell has a pair of opposing sides comprising at least the majority of the boundary surface of said cell and defining a short cell dimension therebetween. The cell comprises an anode assembly and a cathode assembly bonded together to form a laminate structure. The cell comprises preferably two separate plastic frames housing the anode and cathode material. The anode current collector may be precoated with a sealing metal forming an alkaline resistant metal oxide film to improve bonding to the frame. The anode assembly has an anode material therein typically comprising zinc and the cathode assembly has a cathode material therein typically comprising manganese dioxide. The cell is durable and preferably rigid, has elongated leak block paths, and resists electrolyte leakage.

International Classification:

F16D 6900

US Classification:

188 731

Abstract:

A caliper disk brake for steel mill cranes includes a pair of armatures having an electromagnetic coil and a spring interposed between them to operate in a clamshell fashion. The spring urges the armatures apart, while actuation of the coil urges the armatures together. Each of a pair of caliper arms is pivotally connected to a respective one of the armatures at one end thereof, and has a pressure plate pivotally maintained at an opposite end. The pressure plates are maintained in juxtaposition to wear pads which are axially movable in apertures maintained in a pair of stationary plates. A disk, adapted for interconnection with the shaft of a steel mill crane hoist motor is positioned between the plates and wear pads. Actuation of the electromagnetic coil closes the armature and disengages the wear plates from the disk, while deactivation of the coil allows the spring to urge the armatures apart, causing the caliper arms to pivot such that the pressure plates engage the wear pads and force them into braking frictional engagement with the disk. The pressure plates and wear pads are free floating and self aligning.
