This invention relates generally to the field of devices designed to prevent the use of electrical equipment or appliances by securing the electrical plug. More specifically this invention relates to a device which will captivately surround the blades of the electrical plug in such a manner that young children, elderly persons, or mentally retarded persons cannnot gain access to their use, and which incorporates a clamping mechanism which can be actuated without the use of any external apparatus, such as a key or a tool.

Self contained child resistant electrical plug safety lock

An apparatus for securing the prongs of an electrical appliance plug into a block of strong, flexible plastic. The block has a pair of grooves spaced at the appropriate distances to accommodate the parallel prongs of a standard electrical plug. Additionally, the block has an aperture to receive the third, or grounding prong of the electrical plug. A hole, receptive of a bolt, exists at right angles to the direction of insertion of the plug. The hole has a clearance region through the middle and the section of the block adjacent to the bolt head, but is threaded at the section which is opposite the bolt head. The bolt is of the appropriate length to traverse the width of the block when fully tightened into the block. Additionally, the hole may be recessed to form a depression around the bolt head to discourage tampering or probing. Similarly, a recessed region may be formed on the face of the block into which the plug is inserted to likewise discourage tampering or probing. In operation, once the plug prongs are inserted into the block, the bolt is tightened, and retentive force is applied to the prongs of the plug to prevent removal. Optionally, a groove may be positioned on the side of the block, and a hole may be located in the end of the bolt. This combination allows the shackle of a padlock to be inserted into the shank of the bolt, to retain the bolt in the block. Once the bolt is tightened into the appropriate position, the padlock shackle is inserted into hole in the shank. The groove cooperates with the shackle and prevents the loosening of the bolt thereby preventing the release of the plug until the padlock shackle is removed.

The low flow monitor provides a means for determining if a fluid flow meets a minimum threshold level of flow. The low flow monitor operates with a minimum of intrusion by the flow detection device into the flow. The electrical portion of the monitor is externally located with respect to the fluid stream which allows for repairs to the monitor without disrupting the flow. The electronics provide for the adjustment of the threshold level to meet the required conditions. The apparatus can be modified to provide an upper limit to the flow monitor by providing for a parallel electronic circuit which provides for a bracketing of the desired flow rate.

Low volume flow meter

A microscope consisting of an x-ray contact microscope and an optical microscope. The optical, phase contrast, microscope is used to align a target with respect to a source of soft x-rays. The source of soft x-rays preferably comprises an x-ray laser but could comprise a synchrotron or other pulse source of x-rays. Transparent resist material is used to support the target. The optical microscope is located on the opposite side of the transparent resist material from the target and is employed to align the target with respect to the anticipated soft x-ray laser beam. After alignment with the use of the optical microscope, the target is exposed to the soft x-ray laser beam. The x-ray sensitive transparent resist material whose chemical bonds are altered by the x-ray beam passing through the target mater
