Abstract: A double-hinged food press for extruding foodstuff through a grate and operational by hand while held aloft or placed on a work surface. An upward-curved plunger handle, combined with a receiver handle designed to rest on the surface, positions the press for the operation. Rollers enable the grate to be snapped smoothly over risers into and out of recesses in the receiver without undue wear and resulting loss of integrity. A raised lip of resilient material surrounding a plunger face further ensures a tight fit between the plunger and receiver cup. Resilient material between the plunger face and the hinge barrel of the grate ensures a tight fit between the two. Hinge pins may be removed by the user for replacement of the grate. Bosses can extend from the receiver unit for support on the surface to assist in operation of the press. An attachable paddle can be used to collect extruded material and to scrape it from the grate.

Abstract: A rotary grater and/or slicer includes a grater body, the grater body including a cutter housing portion and a vertical hopper portion connected to the cutter housing portion, the vertical hopper portion of the grater body being configured to hold a workpiece for grating; a rotatable cutting device, the rotatable cutting device configured to be rotatably disposed inside the cutter housing portion of the grater body, the rotatable cutting device comprising a plurality of blade members for grating the workpiece; and a rotary input device coupled to the rotatable cutting device, the rotary input device configured to rotate the rotatable cutting device. The vertical hopper portion is configured to serve as a handle for the rotary grater and/or slicer, and the vertical hopper portion is used for feeding the workpiece to the rotatable cutting device.

Abstract: A rotary grater includes a grater body with a body arm portion; a rotatable cutting device; a grater plunger with plunger arm portion connected to a plunger head portion; and a lever member pivotably coupled to the plunger arm portion or the body arm portion, the lever member having a first lever end portion and a second lever end portion, the second lever end portion of the lever member being oppositely disposed relative to the first lever end portion, the first lever end portion of the lever member configured to receive an input force applied by a user, and the second lever end portion of the lever member configured to apply an output force against a bearing wall of the grater body or the grater plunger so as to facilitate a compressing of the workpiece between the plunger head portion and the rotatable cutting device while grating the workpiece.

Abstract: A hinge clamp adapted to clamp a hinge assembly with an eyelet to position and protect a retraction spring, a counter-bore in the V-plate to accommodate the spring, and a finger loop to position the user's finger during operation. In some aspects the clamp may have a removable bolt tightening handle, the release of which enables the handle to be removed to avoid damage and to prevent theft. The handle may be removable over the head of the bolt in a first rotary configuration, and be constrained under the head of the bolt in a second rotary configuration. The hole in the clamp plate is counter-bored on the “V” side to accommodate a spring, which surrounds the bolt.

Abstract: A container is provided for shipping and storing a pre-wetted and pre-conditioned microfluidic “sipper” chip. The container contains both dry compartments and wet compartments. A base contains a fluid-filled reservoir configured to house the capillaries. The opening of the reservoir is sealed with an O-ring. The plastic mount of the chip rests on the base in a dry compartment. The upper surface of the chip contains several wells containing fluid. A gasket is provided with plugs configured to be disposed within and seal the wells. Alternatively, the wells are first sealed with a foil film adhered to the well openings with an adhesive and a gasket is disposed between the foil and a cover, which is removably attached to the base. When the cover is closed, the gasket and O-ring seal the wet compartments to prevent leakage and to slow evaporation.
