Abstract:
A system and method for identifying a key blank from a master key is provided. The system includes a housing, a first source of uniform light fixed relative to the housing, and a second source of uniform light fixed relative to the housing and disposed at an angle relative to the first source of uniform light. A reflecting device is proviced that has a reflective surface and a transparent surface. The reflecting surface is configured to reflect light generated by the second source of uniform light towards the first source of uniform light such that when a master key is disposed in the housing, the first source of uniform light generates a profile image of the master key and the second source of uniform light illuminates a surface of the master key. A receiver is operable to capture an image of the master key through the transparent surface of the reflecting device.
Abstract:
A floating beverage holder for use in water sports. The beverage holder contains a plurality of cavities for holding cans or bottles, and has sufficient volume to provide the required buoyancy and which can support the beverage holder on water when the beverage holder contains combinations of cans and bottles. The design of the beverage holder makes the floating beverage holder virtually un-tipable. A housing is provided in the larger beverage holders for storage of food, ice, or bathing supplies.
Abstract:
A hydraulic pilot valve has a joystick which is normally maintained in a neutral position by coil springs acting on plungers which engage corresponding first cam surfaces of a cam fixed to the joystick. The plungers are each connected to respective valve members which are stroked to open the pilot valve when the plungers are depressed. When the joystick is pivoted to depress one of the plungers by engaging the head of the plunger so as to stroke one of the valve members, that valve member is held stroked by an magnetic detent. The joystick may then be released and the valve member will remain in its stroked position. When the joystick is moved back towards a neutral position, a second cam surface on the joystick engages an outer end portion of the depressed plunger and applies an axial force to the plunger. This disengages an armature component of the magnetic detent from an electromagnetic component. A spring then pushes the plunger to its neutral position where the plunger holds the valve member operated thereby closed. In accordance with one embodiment, one joystick operates four valve members and, in accordance with another embodiment, the pilot valves are stacked. When the joystick operates four valve members, a spring biased sliding cam is mounted on the joystick for engaging the end surfaces of the plunger heads. A cam having four raised, arcuate cam surfaces is fixed to the joystick for engaging frustoconical sides of the plunger heads so that the plunger heads can be trapped between the sliding cam and raised cam surfaces to minimize slop.
Abstract:
Apparatus and method for duplicative notching of the serration edge on a key blank according to the serration edge of an existing key serving as a templet. An axially movable key edge notching punch is controlled by the templet for punching a notch in the serration edge of the key blank corresponding to a notch in the serration edge of the templet when the punch is driven toward the key blank. The key blank and the templet key may be supported in a cassette which is indexible relative to the punch. The cassette and the notching mechanism are especially advantageous for notching the serration edges of key blanks carried by wallet size plastic cards.
Abstract:
A geothermal vault apparatus for use in a geothermal system includes a tank vault to enclose the one or more manifolds of the system. The tank vault includes a tank shell defining an interior volume (e.g., formed of fiber reinforced plastic material), an access opening to permit a person to enter the tank shell, and an arrangement of a plurality of transition fittings located in a cylindrical wall of the tank shell and configured to couple a plurality of energy transfer pipes (e.g., HPDE pipes) to a plurality of ports of the one or more manifolds enclosed within the tank vault.
Abstract:
A method of making a fused silica article having a combined concentration of protium and deuterium in a range from about 1×1016 molecules/cm3 up to about 6×1019 molecules/cm3. In some embodiments, deuterium is present in an amount greater than its natural isotopic abundance. The method includes the steps of providing a fused silica boule, diffusing at least one of protium and deuterium into the boule, and annealing the boule to form the fused silica article. A method of diffusing hydrogen into fused silica and a fused silica article loaded with hydrogen formed by the method are also described.

Abstract:
A system for identifying the key blank corresponding to a master key is provided. The system includes a first luminous surface and a second luminous surface. The second luminous surface is disposed opposite the first luminous surface such that the master key is disposable therebetween. The first and second luminous surfaces are operable to generate an image of the master key. A receiver is provided to capture the image of the master key. The system also includes a control having a memory that stores information on a plurality of key blanks. The control is operable to identify the key blank corresponding to the master key based on the image captured by the receiver.
Abstract:
A feed spring for use in displaying items in a display rack is disclosed. The feed spring comprises a sheet of elastic material configured to be formed into a hollow three-dimensional object. The hollow three-dimensional object is secured to the display rack and is compressible to provides a biasing force to position display items in the display rack. The feed spring is maintained as the hollow three-dimensional object in its uncompressed and compressed configurations by interlocking tabs, adhesives, double sided tapes, or other suitable securement mechanism. The feed spring may be suitably secured to the display rack by attachment to the frames of the display rack or other suitable securement means. Preferably, the hollow three-dimensional object in its uncompressed configuration is a hollow cylinder formed by rolling the sheet of elastic material.
Abstract:
A system for holding or transporting engraveable workpieces of different configurations is provided. The system includes a first workpiece carrier that has an internal relief configured to receive a first workpiece having a first configuration. The system also includes a second workpiece carrier that has an internal relief configured to receive a second workpiece having a second configuration. The outer surface of the second workpiece carrier is substantially the same as the outer shape of the first workpiece carrier, to thereby provide a carrier of uniform outer dimensions regardless of the workpiece configuration. The carrier may hold the workpiece within the internal relief through a snap lock and in such a manner as to avoid contact with and possible damage from an adjacently stored workpiece.
Abstract:
An engraving system for positioning a workpiece to be engraved. The workpiece is held in a workpiece carrier having a positioning structure that engages a complementary positioning structure on an engraving table. The workpiece is centered in the workpiece carrier so that when the workpiece carrier is in position on the engraving table, the center of the workpiece is known to the engraving system. This engraving system allows for an unskilled operator to engrave workpieces of different configurations in a reliable manner.
