Patent number: 6802394Abstract: A self-contained automatic lubricator for automatically dispensing fluent lubricant over a period of time is provided. The lubricator comprises a cylinder having a front wall with a discharge outlet, a rear wall and cylindrical side walls. A piston is movable within the cylinder from a rear position to a forward position. The piston and the side and front walls of the cylinder define a variable volume chamber for containing the lubricant to be dispensed, and a spring for moving the piston from its rear position towards it front position to reduce the volume of the variable volume chamber over a period of time for expelling lubricant through the discharge outlet. The lubricator further comprises a controller including gearing and an escapement mechanism, for controlling the transfer of energy from the spring to the piston and an electrical element controlling operation of the escapement mechanism (12).Type: GrantFiled: September 18, 2002Date of Patent: October 12, 2004Assignee: Wymark LimitedInventors: Denis Arthur John Patterson, Simon Stone

Patent number: 6802395Abstract: A system for controlling the braking of an elevator car during an emergency. When there is a power failure or other emergency, a brake is applied to slow the elevator car to a stop in a controlled fashion. By Controlling the braking, the car is stopped in a short time but without discomfort to the passengers. The controller receives inputs from the rope movement, motor movement, temperature and the braking current to correctly determine the amount of braking which should be applied.Type: GrantFiled: March 28, 2003Date of Patent: October 12, 2004Assignee: Kone CorporationInventors: Brad Helstrom, Don Afman, John Weber

Patent number: 6802396Abstract: A double deck elevator includes a floor height adjusting mechanism that adjusts the distance between the upper and lower decks located within a cage frame. The adjusting mechanism includes a pantograph having an upper portion coupled to the upper deck and lower portion coupled to the lower deck. A central portion of the pantograph is fixed to a portion of the cage frame. A screw is coupled to the upper or lower portion to cause the pantograph to expand and contract to adjust the distance between the upper and lower decks. The screw is driven by a motor located between the upper and lower decks.Type: GrantFiled: July 3, 2002Date of Patent: October 12, 2004Assignee: Otis Elevator CompanyInventor: Yoshiaki Naitoh

Patent number: 6802397Abstract: A parking brake assembly which includes a lever (15) for operation of a brake shoe (11, 12) to provide a parking function. The lever (15) has an automatic latching device (21, 22, 23) for automatically latching to the lever (15) an end fitting (20) on an operating cable (19). The automatic latching device (21, 22, 23) comprises a flap (22) mounted on the lever (15) which is deflected aside by the end fitting (20) as the cable (19) is fed in a first direction towards the lever (15) and which latches behind an abutment (20a) on the end fitting (20) to latch the cable (19) to the lever (15) so that subsequent movement of the cable (19) in a second direction opposite to the first direction moves the lever (15) to opoerate the parking function.Type: GrantFiled: December 8, 1998Date of Patent: October 12, 2004Assignee: Automotive Products Italia (SV) SPAInventors: Davide Matteis, Vincenzo Giardina

Patent number: 6802398Abstract: A manually operated cable release apparatus, suitable for use in an electrically actuated brake, is provided for a locking mechanism having a shaft that is rotatable about an axis of rotation of the shaft, between a first angular position where the locking mechanism is disengaged, and a second angular position where the locking mechanism is engaged. The cable release apparatus includes a lever having one end thereof fixedly attached to the shaft and extending outward from the shaft for applying a force to the lever, for rotating the shaft back and forth through an angular displacement between the first and second angular positions.Type: GrantFiled: July 1, 2002Date of Patent: October 12, 2004Assignee: Delphi Technologies, Inc.Inventors: David B. Drennen, Patrick A. Mescher, Harald Klode

Patent number: 6802399Abstract: A wheel bearing flange with a periphery having axial extensions for the mounting of a flat annular brake disk thereon. An isolating connecting element between the axial extensions and the brake disk. The axial extensions have radially outwardly directed projections which engage in radially inward recesses with the interior of the brake disk. The connecting element elastically pre-loads the brake disk relative to the axial extensions to elastically compensate for displacements of the brake disk while driving.Type: GrantFiled: December 13, 2002Date of Patent: October 12, 2004Assignee: FAG Kugelfischer AGInventors: Peter Niebling, Kay Schumacher, Heinrich Hofmann

Patent number: 6802400Abstract: A braking device for a four-wheel buggy including rear swing arms which are attached to a vehicle body frame such that the rear swing arms can swing vertically, an axle shaft attached to the ends of the rear swing arms, and wheels disposed one at each end of the axle shaft is disposed above the axle shaft. The braking device is constructed as a mechanical braking device including a brake drum and a brake shoe which apply a braking force to the wheels, a brake cam lever which activates the brake, and a rear brake operating cable used for operating the brake cam lever. The brake cam lever is provided with a projecting portion which is formed integrally with the brake cam lever at a position below a connecting portion with the rear brake operating cable, the projecting portion protecting the lower side of the connecting portion.Type: GrantFiled: January 2, 2003Date of Patent: October 12, 2004Assignee: Suzuki Motor CorporationInventor: Kousei Ohura

Patent number: 6802401Abstract: The present invention relates to a device and a method for controlling an electrically actuated parking brake. Especially, a tip switch is provided which is movable to adopt a tensioning position, a release position, and a neutral position. For example, when the tip switch is moved by the driver to adopt the tensioning position, the control unit increases a nominal value of the actuating force of the parking brake. By actuating the tip switch, the driver is thus able to determine which actuating force is used to actuate the parking brake.Type: GrantFiled: November 30, 2001Date of Patent: October 12, 2004Assignee: Continental Teves AG & Co., oHGInventors: Jürgen Böhm, Joachim Nell

Patent number: 6802402Abstract: A braking device that can be released electromagnetically exhibits at least one brake shoe (20), which is pressed against a braking area by the force of a brake spring (14) in order to brake a linear or rotary motion. A magnet system exhibits a coil (1) and an armature (4), while current fed to the coil (1) causes the armature (4) to move against the force exerted by the brake spring (14), with the result that the brake shoes (10) is able to rise from the braking area (13) and thus release the brake. To achieve a high braking force with a magnet system of small structural dimensions the brake force of the brake spring (14) is transmitted from the armature (4) to the brake shoes (10) by at least one pressure element (5) with diagonal wedge areas (7, 8).Type: GrantFiled: June 4, 2002Date of Patent: October 12, 2004Assignee: Kendrion Binder Magnete GmbHInventors: Edmund Bausch, Joachim Hubrich
