| 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 |

| 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 |

| 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 |
| 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 |

| 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 |

| 20130248303 | WET BRAKE DEVICE - A plurality of rotating side brake disks and a plurality of non-rotating side brake disks are arranged outside in the radial direction from a motor shaft in a brake case while alternately overlapping with each other. A frictional material is provided on the non-rotating side brake disk, and an oil groove is provided in a frictional engaging surface of this frictional material. It is configured such that, when a braking force is applied by a brake piston to the motor shaft, lubricant oil flowing into the brake case from a lubricant oil inlet port flows from the outer diameter side to the inner diameter side between the rotating side brake disk and the non-rotating side brake disk only through the oil groove. As a result, the lubricant oil having flowed into the brake case efficiently cools the frictional engaging surface. | 09-26-2013 |

A release rod is coupled to an end of the pivot link remote from the release lever, and a compression spring extends between the end of said pivot link and the release rod, such that the spring will compress in the event the force to move the release rod exceeds the spring constant. This compresses the spring and prevents the release rod from moving to release the clamping brake. The compression spring, in one embodiment, comprises a plurality of stacked Belleville washers. | 11-21-2013 |

| 20140116813 | CENTRIFUGAL BACKSPIN BRAKE - A centrifugal brake system for retarding shaft backspin includes a brake drum, a brake hub attachable to the shaft and two or more brake shoes mounted on the hub for braking engagement with the drum. A mechanical linkage transfers the generated braking force from the brake shoes to the hub and permits radial displacement of the brake shoes relative to the hub, upon rotational shifting of the hub relative to the brake shoes between deactivated and activated positions. In the deactivated position of the hub, the brake shoes are maintained in a radially inward, disengaged position. In the activated position, the brake shoes are radially displaceable by centrifugal force from the disengaged position to a radially outward, engaged position, wherein the brake shoes are in braking engagement.

A one-way stopper mechanism restricts the relative movement of the stopper body with respect to the guide member toward a side at which the gap in the wedge-like space is large, but allows the relative movement toward a side at which the gap in the wedge-like space is small. | 05-15-2014 |
