Publication number: 20160236296Abstract: The present invention provides a nanoparticle manufacturing system differing from conventional nanoparticle fabricating equipment. In this nanoparticle manufacturing system, a laser beam emitted from a laser source is directly guided to the surface of a target disposed in an ablation chamber through a light guide tube, such that the laser beam is prevented from being influenced by reflection and/or refraction effects occurring from the cooling liquid filled in the ablation chamber.

Publication number: 20160236323Abstract: The disclosure concerns a blasting method achieving antistatic effect and increasing processing amount. In the method, 0.06 cc/min to 150 cc/min, that is, a relatively small amount of liquid is introduced into the blast nozzle and atomized by causing it to strike with the compressed gas flowing through the blast nozzle or the compressed gas ejected from the blast nozzle, and the atomized liquid is ejected together with the compressed gas and the abrasive onto the workpiece. Since the relatively small amount of the atomized liquid is quickly evaporated into water vapor, humidity in a working space is increased, thereby generation of static electricity is prevented. A vaporization heat is absorbed during evaporation then the workpiece is cooled, accordingly, absorption of strike energy from the abrasive due to softening of the surface of the workpiece is prevented, as a result, the processing amount is improved.Type: ApplicationFiled: September 17, 2014Publication date: August 18, 2016Inventors: Keiji Mase, Katsuyuki Sakuma

Publication number: 20160236330Abstract: A wrench adapted for use with bonnet nuts of shower valves. The present invention includes a substantially closed end wrench having a pair of disconnected distal ends separated by a gap. The distal ends each include a threaded aperture, each of which are aligned to allow a fastener to be inserted therethrough. As the fastener placed through the pair of complementary threaded apertures is tightened, it draws the distal ends together, thereby closing the head of the wrench. The present invention is used by placing the end of the wrench over the bonnet nut and then tightening the fastener in order to close the end of the wrench around the bonnet nut. The frictional engagement between the interior surface of the wrench end and the bonnet nut around which the closed end is tightened allows the user to apply torque to the wrench to tighten or loosen the bonnet nut.Type: ApplicationFiled: May 7, 2015Publication date: August 18, 2016Inventor: Dustin Popejoy

Publication number: 20160236333Abstract: Methods and systems for increasing the efficiency of a remote wrench. The remote wrench can include a flexible plate within the tool housing or as part of the housing that is more flexible than the rigid housing in conventional remote wrenches that has been shown to limit efficiency. Additionally, a fixed support and a base can be provided that are collectively capable of being coupled to the remote wrench, preferably at the flexible plate, to increase efficiency. The remote wrench operation is therefore improved by reducing inefficiencies and providing a maximum torque output.Type: ApplicationFiled: January 25, 2016Publication date: August 18, 2016Applicant: Snap-on IncorporatedInventors: Anup A. Gupte, Daniel M. Eggert

Publication number: 20160236334Abstract: A method comprises the steps of providing a tool over a collar secured to a stud on a gas turbine engine system. The collet is driven to rotate and remove the collar from the stud. A tool for removing collars from studs has a driver with a housing receiving a piston. A spring drives the piston, and the housing also has a hydraulic fluid supply opening for selectively receiving a hydraulic fluid to move the piston in opposition to a force from the spring. Collet fingers are movable between a released position and a secured position when a supply of hydraulic fluid is supplied into the housing.Type: ApplicationFiled: October 17, 2014Publication date: August 18, 2016Inventors: David J. Eigner, Steven E. Eichner
