Abstract: The disclosure relates to natural oil-based petrolatum compositions and a method of making the same. The natural oil-based petrolatum composition includes the esterification product of: about 0.1 wt % to about 35 wt % a fatty acid dimer, about 5 wt % to about 30 wt % a C8 to C22 fatty acid, and about 65 wt % to about 95 wt % hydrogenated natural oil, wherein the natural based petrolatum product has an acid value of less than 25. Natural oil-based petrolatum compositions can be used in personal care products.

Abstract: The disclosure relates to natural oil-based petrolatum compositions and a method of making the same. The natural oil-based petrolatum composition includes the esterification product of: about 0.1 wt % to about 40 wt % a fatty acid dimer, about 99.9 wt % to about 60 wt % of one or more components selected from the group consisting of C1-C6 polyols, natural oils, fatty acids, and acyls glycerols, wherein the natural based petrolatum product has a cone penetration value of greater than 10 and a polydispersity index greater than 1.3. Natural oil-based petrolatum compositions can be used in personal care products.

Abstract: The disclosure relates to natural oil-based petrolatum compositions and a method of making the same. The natural oil-based petrolatum composition includes the esterification product of a pre-esterification mixture of: about 15 wt % to about 25 wt % a fatty acid dimer, about 15 wt % to about 25 wt % glycerin, and about 55 wt % to about 70 wt % hydrogenated natural oil, wherein the natural oil-based petrolatum product has an acid value of less than 5.0. Natural oil-based petrolatum compositions can be used in personal care products.

Abstract: The Dual Clappet Mask is to protect people from inhaling harmful air around them. They inhale and exhale by the same mouth nipple connected to a dual clappet, and the two clappets are open/close automatically to fulfill the respiring. Unlike filtering the inside air, the Dual Clappet Mask uses outside clean air via a soft tube, and in this way it would protect people very well from a small toxic, dusty and anoxic environment.

Abstract: This Hand Peel Pencil does not need any knife to cut during using. When the writing head is used out, to acquire more writing head people can just use their fingers getting a short cone tube off from the Hand Peel Pencil. In this way people can save time from finding a suitable knife and cutting their pencil from time to time during writing. Also using Hand Peel Pencil can protect environment from the garbage of cutting of pencil.

Abstract: In an ultrasonic tool-guidance system, an imaging module in a housing includes modules for image and beam processing and beamforming. A transmitter and a receiver connect via a switch to a multi-transducer probe. The housing includes a display for providing real-time ultrasound images. The probe includes a tool-guiding channel through which a tool can be inserted into the body of a patient. The transducers are arranged at an angle laterally around the tool-guiding channel. The angled transducers provide overlapping beams that result in a better quality enhanced image of the center area. The probe is rotatably attached to the housing to allow for easy viewing of the ultrasound images during a procedure. The tool-guiding channel is maintained at a fixed angle with respect to the transducers and the probe to assure that the tool remains in the illuminated area throughout the procedure.
