| 439029000 | Including resiliently biased contact | 8 |
| 20100003836 | Rotary Terminal Mechanism - A rotary terminal mechanism ( | 01-07-2010 |
| 20130244451 | BRUSH HOLDER MARKING SYSTEM AND ASSOCIATED MAINTENANCE - A marking system for knowing precisely at which location on an electrical device a used brush and associated brush holder assembly were positioned to evaluate whether abnormal brush wear, abnormal operation or other anomaly is occurring and performing maintenance and/or replacement of components as needed. | 09-19-2013 |
| 20140038434 | Low Cost Gold Wire Brushes - A slipring brush includes a body of a metal wire or metal band having a contact area for contacting a slipring module. The contact area is selectively coated by a contact material like gold or silver or an alloy thereof. The body preferably includes Copper, Nickel, Iron, or an alloy thereof. Coating may be done by electroplating, physical vapor deposition (PVD) or chemical vapor deposition (CVD). | 02-06-2014 |
| 20140045349 | BRUSH HOLDER APPARATUS - Various embodiments include a brush holder apparatus. In one embodiment, a brush holder apparatus for receiving a brush includes: a first support member; a box member affixed to the first support member; and a cam member operably connected to the first support member, the cam member configured to retain the brush against an inner surface of the box member. | 02-13-2014 |
| 20140120744 | RETRACTABLE CONTACT ASSEMBLY - A retractable contact assembly includes an outer casing having a first opening and a piston located in the first opening of the outer casing and moveable axially within the opening. The piston has a second opening. The assembly further includes an inelastic force generating device configured to control an axial movement of the piston and a contact located in the second opening of the piston and movable axially in the second opening of the piston. The assembly further includes an elastic force biasing device configured to provide an elastic force to the contact in an axial direction outward from the second opening. | 05-01-2014 |
| 20150303634 | BRUSH HOLDER ASSEMBLIES AND METHODS FOR MOUNTING AND REPLACING BRUSHES - An assembly has a handle, a brush holder, and a support that connect and disconnect to each other using a locking mechanism. The handle reversibly connects and disconnects from the brush holder. The locking mechanism includes a connecting member on the brush holder that attaches to the handle by interaction of a locking flange on the connecting member with a pair of teeth inside of the handle. Insertion of the support within the brush holder extends a post on the support through the connecting member to interact with the handle and enable disconnection of the handle from the brush holder when the support is fully engaged by the brush holder. The locking mechanism prevents the handle from releasing from the brush holder before the brush holder is completely seated on the support. | 10-22-2015 |
| 20160036183 | PROPELLER DEICING BRUSH BLOCK - A brush block assembly and a method of assembling the same are described. The brush block assembly includes two or more brushes arranged in one or more rows, each of the two or more brushes comprised of a pressed electrically conductive material with an integral lead wire and a terminal, and one or more terminal studs, each of the two or more brush blocks within a same one of the one or more rows being separated by one of the one or more terminal studs, a helical spring coupled respectively to each of the two or more brushes, and insulated wires from a power supply and the respective terminal of each of the two or more brushes within the same one of the one or more rows being retained by the one of the one or more terminal studs in the one of the one or more rows. | 02-04-2016 |
| 439030000 | Contact having resilient shank | 1 |
| 20150349477 | SLIDING CONTACT ARRANGEMENT FOR TRANSMITTING ELECTRICAL SIGNALS AND ALSO A METHOD FOR PRODUCING THE SLIDING CONTACT ARRANGEMENT - The invention is a sliding contact and also a method for the production thereof. The sliding contact arrangement has two parts mounted to rotate relatively to one another. The first part has a metallic carrier ring with radial inner and outer sides, which is monolithically connected to at least one spring arm, which ends freely on one side on the inner side or outer side. The spring arm extends longitudinally relative to the inner or outer side at least in certain sections. The spring arm ends at a spring arm head having a contact surface facing away from the carrier ring, which is in sliding contact with a contact surface of the second part. | 12-03-2015 |
