摘要： Method and apparatus for an improved camlock fitting having outer/inner cam lever which are restrained against unintended opening or rotation by a pivoting locking member which is pivotally mounted onto an axle disposed in a corresponding hole on the cam levers so that the pivoting locking member can be easily pivoted in the vertical plane relative to the cam arms. Each of the outer and inner arms has a pivoting locking member mounted on its underside in a protective housing. The camlock fitting may also have an air vent. Together this provides a safety lock assembly for the cam lock fitting so that when the cam lock fitting is pressurized unbeknownst to the operator and the operator attempts to open the cam lock fitting, the safety lock assembly will prevent operation or complete separation of the male and the female portions of the fitting to prevent inadvertent pressurized discharge of hazardous materials.

摘要： A method and apparatus for an improved rotatable safety cam lock fitting with an air vent, the male and female portions of the cam lock fitting only slightly separate from each other allowing the operator to reclose the cam lock fitting if the operator observes that the cam lock fitting still contains pressurized material. Rotation of the female portion is accomplished by placing a connecting collar on the rear of the female end portion so that the female portion rotates about the connecting collar. The safety lock mechanism operates by placing opposing notches in the end of the male portion so that when the cam levers are opened the male and female portions of the cam lock fitting initially only slightly separate allowing the operator to quickly reclose the cam lock fitting if it contains pressurized material. The rotating female portion easily aligns the cam lobes of the cam lever with the notches on the male coupling so that the male and female portions can be separated.

摘要： A method and apparatus for an improved safety cam lock fitting having ergonomically designed double cam levers having outer and inner portions so that when the outer cam levers are opened and the inner cam lever remain closed, the male and female portions of the cam lock fitting only slightly separate from each other allowing the operator to quickly reclose the cam lock fitting if the operator observes that the cam lock fitting still contains pressurized material. This is accomplished by providing a larger cam lobe on the outer cam lever and a smaller cam lobe on the inner cam lever so that when the smaller cam lobe is in a closed position and protrudes into a peripheral groove on the male portion the male and female ends have a small space therein between. Various configurations of the cam portions relative to each other are provided. Various lever locking assemblies may be used to prevent the cam levers from being inadvertently opened.

摘要： Embodiments of a method and apparatus for removing metallic nanotubes without transferring CNTs from one substrate to another substrate provide two methods of transferring a thin layer of crystalline ST-cut quartz wafer to the surface of a carrier silicon wafer for subsequent CNT growth, without resorting to CNT transfer. In other words, embodiments of a method and apparatus allow CNTs to be grown on the same substrate that metallic nanotube removal is performed, therefore eliminating the costly and messy step of transferring CNTs from one substrate to another. This is achieved through a residual thin layer of crystalline ST-cut quartz layer on a silicon wafer. The ST-cut quartz wafer promotes aligned growth of CNTs, while the underlying silicon wafer allows backgate burnout.

摘要： Disclosed is a method and apparatus for a handheld, pistol-grip type rotatable spatula having a pair of reciprocating spatulas on the front end which captures a food item, holding it in place between the pair of spatulas, and then rotating the food item approximately 180 degrees so that it will allow the user to easily turn a food item over, which item might be for example, on a cooking grill. The apparatus allows the user to turn or flip the food item over and gently lay the food item down without having to twist the wrist of the user. The apparatus allows a simple motion of the rear pistol grip type handle to be squeezed and compressed in the hand of a user so that the pair of spatulas holding the food come together holding the food therein which then allows the food to be rotated.
