Abstract: Chemical reactor (10) and method for cracking are disclosed. A process fluid is accelerated with axial impulse impellers (40A, 40B) to a velocity greater than Mach 1 and, in turn, generating a shock wave (90) in the process fluid by decelerating it in a static diffuser (70) having diverging diffuser passages (72). Temperature increase of the process fluid downstream of the shockwave cracks or splits molecules, such as hydrocarbons entrained in the process fluid, in a single pass, through a unidirectional flow path (F), within a single stage, without recirculating the process fluid for another pass through the same stage. In some embodiments, a system involving at least two turbomachine chemical reactors (110) may provide multiple successive stages of one or more axial impulse impellers (40A, 40B), paired with a diverging passage, static diffuser (70).

Abstract: The invention provides a fire-stopping product, an insulated building façade comprising a fire-stopping product, and a method of making a fire-stopping product. The fire-stopping product comprises a resilient, porous material at least partially impregnated with an intumescent agent and held in compression by a releasable restraint. When exposed to hot gases from a fire, the restraint yields to release the resilient, porous material in an initial expansion, thereby exposing the intumescent agent to the hot gases and allowing rapid intumescence to occur. When implemented in a ventilated building façade, the fire-stopping product is able to close an air gap in a short amount of time.

Abstract: Systems and methods are provided for measuring and identifying real-world tremors in order to calculate and display an anti-tremor in a virtual reality world. A system may identify a tremor in a body part, such as hands, and measure the tremor movement from, e.g., body sensors, to calculate an opposite movement and animate virtual hands performing the reverse tremor motion. Depicting inverse motions, such as an anti-tremor, may be used in a few ways to therapeutically train and exercise patients to better control their tremors. Providing a visual cue may help a patient interrupt the movement, as well as provide possibilities for therapy or training muscle memory and stimulating nerve and neuron recovery. By displaying an anti-tremor with virtual hands, a VR system may be used to help train or exercise body parts experiencing tremors.

Abstract: An installation tool configured to install a machine of an elevator system, including a base section including two legs, each leg including a laterally extending gusset attached thereto. A clamp assembly is supported by the base section and includes a first bracket attached to and positioned over the two legs and a second bracket attached to and positioned over the gussets. A first tube is movably carried by the first bracket and a second tube is movably carried by the second bracket. The first and second tubes are movable in the brackets between a retracted position that positions the machine over the base section and an extended position that positions the machine in a cantilevered position adjacent the retracted position.

Abstract: Virtual Reality systems may be used in healthcare and therapy, e.g., focusing on physical and neurorehabilitation. For instance, victims of brain injury may seek treatment to improve, e.g., range of motion, balance, coordination, joint mobility, flexibility, posture, endurance, and strength. VR systems can be used to entertain and instruct patients in their movements while recreating practical exercises to further therapeutic goals. Patient movement data during physical therapy sessions may be valuable to patients and healthcare practitioners. The system may comprise a plurality of body sensors, a VR headset, and a supervisor tablet. The disclosed system may facilitate translation between real world coordinates and virtual world coordinates, assigning sensors to body parts, measuring range of motion of joints and limbs, correcting sensor orientation, recording and presenting therapy data, and generating and animating a 3-D virtual reality avatar in a virtual world to perform activities, among other benefits.

Abstract: A range of alloys of Mg and at least one of Cu, Si, Ni and Na alloys that is particularly suitable for hydrogen storage applications. The alloys of the invention are formed into binary and ternary systems. The alloys are essentially hypoeutectic with respect to their Cu and Ni contents, where one or both of these elements are present, but range from hypoeutectic through to hypereutectic with respect to their Si content when that element is also present. The terms hypoeutectic and hypereutectic do not apply to Na if it is added to the alloy. The alloy compositions disclosed provide high performance alloys with regard to their hydrogen storage and kinetic characteristics. They are also able to be formed using conventional casting techniques which are far cheaper and more amenable to commercial use than the alternative ball-milling and rapid solidification techniques which are much more expensive and complex.

The system further includes a first zone busbar located at the leading edge of the heater mat and electrically coupled to the first zone element.

In some embodiments, the turbomachine chemical reactor (110) has multiple successive stages of one or more axial impulse impellers (40A, 40B), paired with a diverging passage, static diffuser (70). Successive stages crack additional hydrocarbons by successively raising temperature of the flowing process fluid.
