A self-pulling corkscrew is provided. The corkscrew includes a body comprised of a first arm extending downwardly from a central portion and a second arm extending downwardly from the central portion. The first and second arms each having an inner surface and an outer surface wherein the inner surfaces of the first arm and the second arm cooperatively define a bottle receiving cavity. The corkscrew further includes a first groove traversing at least a portion of the outer surface of the first arm and a second groove traversing at least a portion of the outer surface of the second arm. One of either the first and second grooves has a first depth at a proximate end of the groove and a second depth at a distal end of the groove. The corkscrew is further comprised of a sleeve, a handgrip and a screw. The sleeve is slidably engaged with the first and second arms and has a first inwardly projecting protrusion and a second inwardly projecting protrusion. The first protrusion cooperatively engages the first groove and the second protrusion cooperatively engages the second groove. The handgrip is attached to the body proximate the central portion, and the screw is coupled to the handgrip. The screw extends into the bottle receiving cavity between the inner surfaces of the first and second arms.

A system for generating photomask orders in a specified format includes at least one template or order for entry and storage of photomask order data, wherein the at least one template or order is created based upon requirements of a specified photomask order format. The system includes at least one set of rules corresponding to the at least one template or order, wherein the set of rules includes instructions which insure that a user enter complete information into the at least one template or order as required by the specified order format. The templates or order may be further comprised of components and/or subcomponents which can be stored separately. The data fields in the orders, templates, components, subcomponents, etc. may reference specification grades which can in turn be easily modified to update one or more orders, templates, components, subcomponents, etc. simultaneously.

A microinjection pump for administration of fluid pharmacological compounds to unrestrained and freely behaving animals is provided. The micro-pump employs a screw drive mechanism that is actuated by a small stepper motor. The pump moves fluids by direct mechanical displacement from two micro-syringes arranged in parallel. The drive mechanism incorporates a threaded central drive screw that is attached to the stepper motor drive shaft, The threads of the central drive screw engage the threads of two parallel, but oppositely turned (left hand turned and right hand turned) threaded rods. By the frictional action of the helical threads of the threaded drive screw with the threads of the threaded rods the threaded rods are moved linearly and depress the plungers of the attached micro-liter syringes. Medications are administered to animals through flexible tubing. An attached electrical swivel allows power to be delivered to the pump motor while allowing the micro-injector to pivot and move with the animal without binding or twisting the flexible tubing.

A food mincer assembly comprises a handle assembly, a retractable blade cover, and a plurality of blades. The handle assembly has a first side and a second side. The first side has a first through hole and the second side has a second through hole. The retractable blade cover has a cover portion, a lock, and a connecting arm. The connecting arm attaches the blade cover to the handle assembly. The lock secures the blade cover in a first position or a second position. The plurality of blades attach to the handle assembly. The first position of the retractable blade cover covers the plurality of blades. The second position of the retractable blade cover exposes the plurality of blades.

The present invention makes available methods and reagents for modulating proliferation or differentiation in a cell or tissue comprising contacting the cell with a hedgehog agonist, such as the compounds depicted in FIGS. 32 and 33. In certain embodiments, the methods and reagents may be employed to correct or inhibit an aberrant or unwanted growth state, e.g., by antagonizing a normal ptc pathway or agonizing smoothened or hedgehog activity.

A system for generating photomask orders in a specified format includes at least one template or order for entry and storage of photomask order data, wherein the at least one template or order is created based upon requirements of a specified photomask order format. The system includes at least one set of rules corresponding to the at least one template or order, wherein the set of rules includes instructions which insure that a user enter complete information into the at least one template or order as required by the specified order format. The templates or order may be further comprised of components and/or subcomponents which can be stored separately. The data fields in the orders, templates, components, subcomponents, etc. may reference specification grades which can in turn be easily modified to update one or more orders, templates, components, subcomponents, etc. simultaneously. A graphical user interface may be associated with the at least one template or order, wherein the user can access the at least one template or order to enter photomask order data and create an order in a specified format. Alternatively, a command line generator may be used to allow a user to enter commands to generated and/or modify templates and orders. In one embodiment, preexisting data or information may be imported in the form of electronic information and be converted to populate data fields in an order, template, components and subcomponents, etc. A data processing mechanism may also be used to import electronic information from external media into the at least one template or order.
