724 results about "Bolster" patented technology

A bolster is a long narrow pillow or cushion filled with cotton, down or fibre. Bolsters are usually firm for back or arm support or for decorative application. They are not a standard size or shape and commonly have a zipper or hook-and-loop enclosure. A foam insert is sometimes used for additional support. A bolster is also referred to as a cushion, a pillow and a prop.

Hydraulic device for the injection of bone cement in percutaneous vertebroplasty

The present invention relates to the medical field, in particular relates to the practice of percutaneous vertebroplasty where a pair of syringes in the distal extreme of a lengthened hydraulic device, are united by a camera of intermediate connection of larger diameter (pressure exerting body) or modified inverted syringe tube with a bolster, a hydraulic connecting tube of flexible material that transmits the pressure of the smaller diameter manual or impulsion syringe in the proximal extreme of the device toward the intermediate cylindrical larger diameter camera (pressure exerting body), this camera is in an inverted position with regard to the first syringe (fluid control), this intermediate camera has a moving piston longitudinal to the axis of the cylinder that is controlled with the first syringe (manual) and in cooperation with the atmospheric pressure. The injecting syringe loaded with bone cement is coupled with the bolster of the body of pressure, and to the needle that drives the cement toward the interior of the bone. The intermediate camera (pressure exerting body) together with the hydraulic tube and the manual syringe form a hydraulic press system (F/A=f/a) that allows to increase in a potential way the pressure exerted in the first syringe and to make the injection of polymethylmethacrylate (PMMA) at an approximate distance of 1.0 m to 1.5 m.

Adjustable Bolster Swing Legs for Mounting and Aligning and Reorienting Crawlers for Slipform Paving Machines

A paving machine which is configured to move in a paving direction for spreading, leveling and finishing concrete into a form having a generally upwardly exposed, finished concrete surface and terminating in lateral concrete sides. The paving machine has a main frame, including a center module, bolsters laterally movably connected to respective lateral sides of the center module for changing a spacing between the bolsters, and a crawler track associated with respective aft and forward ends of the bolsters. A bolster swing leg for each crawler track supports an upright jacking column secured to the swing leg proximate a free end thereof. A worm gear drive between the jacking column and the crawler track permits rotational movements of the crawler track and the jacking column about an upright axis. A hinge bracket is interposed between each swing leg and an associated surface of the bolsters and includes a fixed, upright pivot shaft that pivotally engages the swing leg to enable pivotal movements of the swing leg about an upright axis in a substantially horizontal plane. The hinge bracket further includes a pivot pin that is laterally spaced from and fixed in relation to the pivot shaft. A length-adjustable holder capable of being held at a fixed length has a first end pivotally engaging the pivot pin on the hinge bracket and a second end that pivotally engages the swing leg. The holder permits pivotal motions of the swing leg about the hinge pin when it is in its length-adjustable configuration and prevents substantially any motion of the swing leg when the holder is in its fixed-length configuration. A feedback loop cooperates with angular position transducers and automatically keeps the crawler tracks oriented in the paving direction of the machine when the swing legs move in a horizontal plane relative to a remainder of the paving machine. The paving machine can be reconfigured between its paving orientation and a road transport orientation by activating the crawlers to move the swing legs and the crawlers into a narrowed transport configuration.
