Abstract: Surgical instruments and devices for creating surgical working spaces and related methods are disclosed. An example surgical spacemaking device may include surgical spacemaking device an elongated connecting portion and an expandable spacemaking portion disposed distally on the connecting portion. The spacemaking portion may include an expandable lateral base portion. an expandable first vertical lateral portion configured to extend generally orthogonally from the lateral base portion, and an expandable second vertical lateral portion configured to extend generally orthogonally from the lateral base portion.

Abstract: Systems, devices and methods for a surgical training tool that drives movement of an organ in order to reproduce a movement of that organ to mimic the conditions of a live surgical procedure.

Abstract: A safety label for use with chafing fuel cans capable of providing the user with information about the current physical characteristics of the can, including as they relate to temperature, employing the use of thermochromic materials dispersed within a media such as ink or paint. The thermochromic materials are capable of undergoing a sharp, reversible visible metachromism between the temperatures of −40° C. and 80° C. The method of manufacturing safety labels according to the invention include the steps of applying informational indicia on the safety label, and then covering such indicia with the media containing the thermochromic materials dispersed therein. When the chafing fuel can is ignited, the media with the thermochromic materials visually undergoes a metachromism, rendering the media invisible, thereby revealing the informational indicia applied with the non-thermochromic ink.

Abstract: A method of initiating an operation in dependence on the combined mass of an element and matter which is in or on the element can be used to remove matter which has accumulated on the rotor of a centrifuge. A substantial change is effected in the speed of rotation of the rotor and the rate of change is then measured. The operation is initiated when the rate of change is above or below a predetermined value.

Abstract: An improved fluid jet bulking device is disclosed in which a yarn feed needle is eccentrically positioned with respect to a venturi and is further provided with a staged means for generation of turbulence in the yarn bulking fluid. The needle may include a flanged end portion which develops a first stage of turbulence generation in the fluid within the venturi inlet, an accelerated flow passage. A second stage of turbulence generation at the distal end of the yarn feed needle augments the level and intensity of turbulence generated in the compressible fluid passing through the device. Fluid flow in the venturi inlet is non-axisymmetric due to the eccentricity so that the successive stages of turbulence generation interact with one another to develop a highly complex turbulent flow regime.
