| 20130075204 | LOAD-INDEPENDENT MOTION CONTROL SYSTEM - A motion control system configured to control motion of a load object independent of the load object, includes a main housing having an internal nut secured with respect to a longitudinal axis of the main housing, and a threaded helical gear movably secured within the main housing. The threaded helical gear includes an end configured to be operatively secured to the load object. The helical gear threadably engages the internal nut. One or both of a first frictional force between the helical gear and the nut or a second frictional force between the nut and at least a portion of the main housing provides a resistive force that controls motion of the load object. | 03-28-2013 |
| 20100263968 | Pole mounted brake - A pole mounted brake device has a unitary body with a passage through which the pole extends. The body is connected to the bottom of the planter, bird feeder, light fixture, or other container which is height adjustably mounted on the pole. A control element is biasedly positioned within the body for adjusting the vertical position of the body and the container on the pole. The control element is configured such that when it is pressed and slid downward within the body, the brake device which is connected to the container controls the movement of the container along the pole. When the pressure on the control element is released, the brake device and thus the container become immobilized on the pole. The pole brake also has application for controlling the movement of horizontally positioned, pole supported containers or objects. | 10-21-2010 |

| 20100252373 | FRICTION DEVICE FOR A SPRING CYLINDER - A positionable support device employs a motion restriction device retrofitted to an existing spring cylinder to adjust the amount of force exerted. In one embodiment, split ring is pressed against an actuating shaft of the spring cylinder with adjustable force. The force on the split ring causes frictional resistance to the motion of the shaft thereby reducing the force applied. This is useful in spring-loaded positioners which allow the object to be placed, and remain in a selected position. The spring cylinder may be gas-charged or spring-loaded support. Various types of friction adjustment units may be employed to result in a positionable support device which holds an object in a desired position. | 10-07-2010 |
| 20100243383 | CLAMPING DEVICE - A clamping device with a housing, a spindle which is rotationally mounted in the housing, and an elastic clamping element, the clamping element being movable by application of a force out of a first position in which the spindle can be turned into a second position in which the spindle is clamped by the clamping element. The clamping element has an inner cylinder which surrounds the spindle to be clamped, an outer cylinder which is located coaxially to the inner cylinder, and a membrane which connects the inner cylinder to the outer cylinder. The clamping element is annular and roughly cup-shaped with an opening in the middle of the clamping element so that the inner cylinder surrounds the spindle to be clamped. The clamping element is shaped and arranged such that, by applying a force to the clamping element the curvature of the membrane can be changed. | 09-30-2010 |
| 20100065384 | Hand Controlled Stopping Device for a Camera Dolly - A braking system allows for smooth and accurate stopping of a camera dolly operating on tracks. A pair of caliper brake modules attached to the dolly frame are sized so that they fit over and at least partially surrounds the track. When the caliper brakes are activated, brake pads are moved towards the surrounded track squeezing it and providing a significant braking force. This permits the dolly to be smoothly brought to a stop with no possibility of the dolly wheel locking and skidding. The braking system can be temporarily attached to the dolly by a removable fastener system, or it can be permanently built into the dolly. A master hydraulic cylinder with a conveniently placed actuating lever is connected to the brake caliper modules by hydraulic lines so that slave hydraulic cylinders can apply the brakes in response to the actuating lever. | 03-18-2010 |
| 20090145700 | FAST BRAKING DEVICE FOR GRINDING MACHINE - A fast braking device for a grinding machine installed in a grinding machine with a spindle comprises: an electromagnet element closely neighbors an inner braking disc; the electromagnet element and the inner braking disc are jointly fixed on the grinding machine. An outer braking disc is separated from the electromagnet element by a lining plate and axially slidably installed on the electromagnet element. Elastic elements are arranged in between the inner braking disc and the outer braking disc. The lining plate rotates synchronously with the spindle. When the user intends to stop the operation of the grinding machine, the electromagnet element provides magnetic force to make the inner and the outer braking discs clamp the lining plate to fast brake the spindle of the grinding machine. Then, the elastic elements separate the outer braking disc from the inner braking disc, and the spindle of the grinding machine can rotate again. | 06-11-2009 |
| 20100307872 | Mechanically Dampening Hold Open Road - A hold open rod is provided. The hold open rod includes an outer tube, a lock body connected to the outer tube, an inner tube, slidingly disposed within the outer tube and lock body, the inner tube having an outer surface, and a friction pad captured between the lock body and the outer surface of the inner tube. A method for damping movement of a telescoping rod is also provided. The method includes attaching the locking body to an outer tube, configuring the outer tube and the inner tube to move with respect to each other in a telescoping manner, fitting a damper between an outer diameter of an inner tube and a locking body, and fitting the damper to frictionally engage the outer diameter of the inner tube and the locking body. | 12-09-2010 |
| 20090308699 | BRAKING DEVICE OF MEASURING INSTRUMENT AND MEASURING INSTRUMENT - A braking device of a measuring instrument includes a body case and a spindle that penetrates the body case to be axially and reciprocably displaceable. The braking device includes a cylinder of which a first end is attached to the body case for accommodating a second end of the spindle, a piston provided on the second end of the spindle and accommodated to be reciprocably displaceable within the cylinder, a closing member provided on a second end of the cylinder to form a damper chamber between the closing member and the piston; a shaft connected to a side of the piston opposite to the spindle and penetrates the closing member; and a knob provided on a distal end of the shaft. A clearance is provided between the closing member and the shaft to circulate air. | 12-17-2009 |

| 20120279812 | Methods and apparatus for a reconfigurable surface - In exemplary implementations of this invention, a pin based mechanism creates physical three dimensional contoured surfaces from a CAD input. When the digital design is downloaded into the device a pin array is collectively actuated to the desired geometry. An optional rubber interpolation layer is held onto the tops of steel pins to prevent undesired dimpling of the surface caused by the discrete nature of the pin array. A single mechanically actuated plate moves all of the pins in the pin array. The device works by pulling all of the closely packed steel pins simultaneously in one direction via a moving plate. As the pins move, they are individually braked and held in position by a phase-changing brake array, integrated with input circuitry. When the plate reaches the end of its stroke, all pins are in the proper configuration. | 11-08-2012 |
