Abstract: First adapter (10) and second adapter (40) are each separately securable to a respective automotive light bar (200, 201) at mutually facing lateral light bar end caps (206). The adapters (10, 40) interfit, such as first adapter (10) having one or more tenons (14; 18) received in shape-conforming recess or mortise (44) of second adapter (40). The coupling assembly formed from interfit first and second adapters (10, 40) sufficiently supports a midspan region of conjoined light bars (200, 201) to permit omission of mounting L-brackets (208) conventionally required at the mutually facing light bar ends (206), thus allowing fewer holes to be drilled in vehicle roof or bumper (212) and resulting in an aesthetically cleaner presentation of the overall lengthened light bar assembly.

Abstract: A ceramic deep-frying device capable of withstanding high temperatures and releasing far-infrared energy is made by grinding and mixing mullite, spodumene, energy ceramic material, ball clay, and kaolin clay into clay blank; molding the blank into ceramic green body; and sintering the green body at 1250-1320° C. for 18-24 hours. The device is completely immersed in the oil in a deep-frying vessel while leaving a gap between the device and heating pipe in the vessel or the inner bottom wall of the vessel, for enabling the oil to circulate through the through holes in the device due to temperature difference in the oil, causing the energy ceramic material to release anions and far-infrared rays that decrease van der Waals forces between oil molecules, and hence split, the oil molecules, thereby extending the service life of the oil, shortening the deep-frying time required, and lowering the oil content of deep-fried food.

Abstract: A formable structure comprises a first material having a first level of viscosity and a second material having a second level of viscosity, wherein the second material is formed to hold at least a portion of the first material in a particular position or a particular shape. The first material can be configured to function as a thermal interface between two or more hardware components. The second material can be configured to have a higher viscosity than the first material. In one illustrative example, the second material can include a light-activated resin that is configured to harden when exposed to one or more treatments. By the use of the first material and second material, the techniques disclosed herein are adaptable to gaps having a wide range of sizes, which is difficult to do with traditional thermal interface materials.

Abstract: A radial compression mechanism utilizes a string wrapped around a plurality of compression dies to move the dies inward and close a central cylindrical cavity defined by the working surfaces of the dies. The string may be coupled to a string tension mechanism that enables a user to applied a desired tension to the string and thereby compress an article within the central cylindrical cavity. The compression dies may be coupled to a base and move along die-guiding slots from an open position to a closed position. A spring may be configured to force the compression dies open and provide some back-tension to the string. The string may extend around a pully on an opposing side of the compression mechanism and both ends of the string may be coupled to the string tension mechanism.
