Abstract: A formation fracturing method with which to mitigate risk to hydrocarbon productivity includes pumping fracturing fluid, during at least part of a fracturing job time period, into a well to fracture a formation; generating signals, within the fracturing job time period, in response to at least one dimension of the fracture; and further pumping fracturing fluid, within the fracturing job time period, into the well in response to the generated signals. Further pumping includes controlling at least one of a pump rate of the further pumping and a viscosity (either fluid viscosity or particulate concentration) of the further pumped fracturing fluid. Control can include comparing a measured magnitude of at least one dimension of the fracture represented by the generated signals with a predetermined modeled magnitude of the same dimension. Tiltmeters can be used to sense fracture height and width, for example.

Abstract: A device and method for use in preventing laminitis in the foot of a horse includes a boot which is formed and adapted to fit over the horse's hoof. A bladder is positioned inside of the boot and beneath the frog of the horse's hoof. A pump is connected to the bladder and pulsates the bladder to provide pulsating pressure to the frog of the horse's foot to simulate the pressure applied to the frog when the horse is walking. Pulsation of the frog has the effect of removing fluid which may tend to cause a softening of the area where the coffin bone of the horse's foot attaches to the hoof.

Abstract: A device for applying cryogenic compression for use in diminishing hemorrhage and edema in acute trauma of body extremities is formed by a sleeve having a plurality of adjacent non-communicating cryogenic chambers and a plurality of coextensive pressure chambers, there being a pressure chamber for each cryogenic chamber. There are fill openings for each cryogenic chamber and inlets for each pressure chamber. A pump is connected to all of the pressure chamber inlets to apply intermittent pressure to one or more of the pressure chambers to thereby apply intermittent cryogenic pressure to an area of a body extremity coextensive with one or more of the cryogenic chambers.
