摘要:
The present disclosure features methods and systems for direct-parametric interoperability in computer-aided design. Two approaches for developing three-dimensional designs are currently widely used: direct and parametric computer-aided design (CAD) modeling. To combine advantages of both approaches, in one aspect of the present invention, a direct modeling user interface is used for editing a model, allowing intuitive and easy manipulation of geometry, and a parametric geometry engine interprets these manipulations as history-based features to create a construction recipe. Thus, the underlying architecture of the model remains parametric, even though the user may not realize that history and associative relationships are being created and modified during every manipulation. Accordingly, the present invention provides the intuitive WYSIWYG editing of direct CAD modeling, while retaining the powerful features and regenerative capabilities of parametric modelers.
摘要:
The present disclosure features methods and systems for enforcing parametric constraints in a direct modeling interface in computer-aided design (CAD). A parametric geometry engine of a CAD application may compare an attempted edit to a feature in a direct modeling user interface of the CAD application to an existing constraint created in a parametric modeling user interface, and, in one embodiment, prevent the user from completing the edit. In other embodiments, the parametric geometry engine may present a dialog box to the user and allow them to reject the edit, override or delete the constraint, modify the constraint, or take other actions as appropriate. In still other embodiments, the parametric geometry engine may allow one user to edit the feature, but not another user. Thus, parametric constraints and permissions-based ownership of entities may be enforced in a direct modeling user interface.

The present invention provides a series of new and improved compounds/materials as vehicles to delivery degradative enzymes to remove/remedy environmental pollutants. The inventive material comprises a series of amide-functionalized ordered mesoporous carbon (AFOMC), which utilizes chemical conjugation techniques for the tethering of enzymes to the surface of the synthesized AFOMC. The delivery mechanism may be utilized to express a wide variety of toxin-degrading enzymes for removal/remediation of organic pollutants.

Disclosed is a composition and process of manufacture of a stir-in form of pigment with increased dispersing and color properties. Pigment is slurried with acetylenic dispersing agents, wet-milled to a particular particle size, and then dried to powder or granulate form. Also disclosed is a process for producing a pigmented paint composition from the stir-in pigment.

Phthalocyanine pigments having 0-4 chlorine atoms have a narrow particle-size range with 90% of particles between about 0.01-0.10 μm, the average particle size of no more than about 0.5 μm, a D99 of no more than about 0.3 μm, and a polydispersity of about 2.0 or less. Pigment compositions contain the phthalocyanine pigment and water-based dispersing resin. The pigments and the compositions are compatible with waterborne coating systems, exhibit an excellent metallic down travel, and are especially useful for the automotive painting applications.

A single ducted valve assembly provides an integrated cryopump valve having a purge valve port connecting the assembly to a cryopump with a coaxial connection having an inner duct and an outer duct. A pressurized gas interface connects a pressurized gas source to the cryopump through the inner duct. A rough valve port can connect the outer duct of the assembly to a rough vacuum pump; and a relief valve port can connect the outer duct of the assembly to an exhaust stack.

The flag caddy of the present invention is useful for safely storing multiple flags and a flag pole and includes a rectangular housing with a door that allows a user to hang multiple flags on horizontal flag rods rotatably positioned within the housing. The flag rods rotate horizontally to allow the safe placement of a flag while several other flags are hanging on similar flag rods. A flag pole storage sleeve is also included and allows the safe storage of a detached flag pole. A hanger or hook attached to the top portion of the housing allows the flag caddy to be stored in a closet or in the garage to protect multiple flags from damage, destruction, dirt and wrinkles.

The present invention contemplates a system for controlling a vibratory conveyor on which a conveyor pan is mounted, the system including a drive coil for driving the vibratory conveyor with a vibrating motion; a sensing subsystem for detecting the vibrating motion of the conveyor pan; a controller coupled to the sensing subsystem for generating at least one control signal to be applied to the drive coil, the controller generating at least one control signal by producing a digitized signal from the detected vibrating motion and computing three intermediate timing positions in each period of the digitized signal; and a switching subsystem for applying at least one control signal generated by the controller to the drive coil. At least one control signal is applied between the first and third intermediate timing positions in each period of the digitized signal to control the vibration amplitude and vibration frequency of the vibratory conveyor.
