A Static Compression Device (SC device) for active, measurable compression of a fusion graft by the surgeon at the time of surgery is disclosed. The SC device is attachable to adjacent vertebral bodies or other pieces of bone and has a device that applies compressive force to the adjacent vertebral bodies or pieces of bone to assist fusion according to Wolffs law. The SC device has a locking mechanism that maintains the compression applied at surgery, but prevents further compression (settling) from occurring after surgery. The SC device allows the surgeon the ability to compress a segment, measure the applied compression, and lock the segment in the compressed position. In one embodiment of the invention, the pressure is applied to the SC device through a compression device that applies a desired and measurable amount of force. In this embodiment, the combination of the SC device with a pressure applying and measuring device allows the surgeon more control over the force applied to a cervical, thoracic or lumbar implant than has previously been available. In the preferred embodiment, the SC device compresses two or more adjacent vertebrae across an adjacent bone graft to facilitate fusion of these vertebrae to treat pain produced by pressure from the disks between such vertebrae bulging and resulting in contact with and pressure on the spinal cord and adjacent nerve roots. In other embodiments, the SC device may be used to apply measurable compression across any type of bony interface (e.g. fractures) to facilitate union.

The lower punch is connected to a system for uncoupling the members that provide the movement thereof, the system having a brake for limiting the downward travel of the lower punch to keep it in contact with the powder material contained in the die when producing the solid product to avoid the generation of additional compression during the receipt of powder material in the die during the intermediate filling phases for each layer of the product.

When a program of a certain duration is converted into compressed data (encoded), it is desirable for the total number of data to fit in an available data space, for example, when recorded on an information carrier. More particularly in variable bit rate compression such as a video signal via MPEG-2, this is hard to forecast. For this purpose, a recording device according to the invention comprises a compression unit (22) whose bit rate is influenced by a system controller (45) via a control input (26) during the encoding process in dependence on the remaining part of the vacant data space on the information carrier (1) and the remaining duration of the program. When parameters influencing the bit rate are set in the compression unit (22), the system controller will take the complexity of the program derived during a previously encoded part of the program into account.

Floating hose is normally comprised of a carcass that is covered with a layer of foam to provide buoyancy. The foam can be deformed and compressed by being repeatedly reeled onto a drum under conditions of high axial forces (reeling forces plus hose weight). The propensity for the foam layer to become compressed is aggravated in typical conditions where the hose is stored on a reel for extended periods and is on the reel more than it is in the water. In any case, compression damage causes the hose to lose buoyancy which can ultimately result in the hose sinking under conditions of normal use. It would accordingly be desirable to develop a floating hose that minimized the permanent damage caused by the foam layer being compressed to high levels over and over again. The floating hose of this invention is resistant to damage that can be caused by axial forces, such as those encountered while being collected on a reel. More specifically, the floating hose of this invention is not as susceptible to being damaged by compression as conventional floating hoses. This is by virtue of the floating hoses of this invention including anti-compression collars that protect the floatation medium therein from damage that can occur during routine usage. This extends the service life of the floating hoses of this invention and reduces their propensity to lose buoyancy over time. The present invention more specifically discloses a floating hose comprising: a carcass having an inside and an outside; a plurality of anti-compression collars interspaced around the carcass; a floatation medium surrounding said hose carcass and said anti-compression collars, and an outer cover, wherein said outer cover covers said floating medium and said anti-compression collars.

A biological fluid testing and collection device includes a container, a cartridge, and a collection stick. The cartridge is configured to rest within the container and seat itself just above a reservoir at the bottom of the container. The collection stick acquires a liquid sample on a pad and is inserted within the container inside the internal cartridge. The pad is compressed against a screen on the cartridge to release the liquid sample. The liquid sample falls through apertures in the cartridge and collects centrally within the reservoir. The testing strips are located externally around the cartridge and contact the reservoir surface. The testing strips are routed to point centrally in the reservoir and extend beneath the pad. A port in communication with the reservoir may be used to permit the removal of liquid sample within the reservoir without removal of the collection stick.

A device absorbs shock in a pneumatic tool containing a body, a cylinder, a valve unit, a piston member, plural buffer springs, and multiple fitting sleeves.
