Abstract: An integrated medical bite block is engaged by a user's teeth and installed into the user's mouth. The bite block includes a through passageway, an upper grove, and a lower grove. The through passageway is penetrating through the bite block. One end of the through passageway comprises an inlet opening, the other end comprises an oral opening. The oral opening is connected with the user's mouth. An upper surface of the bite block provides the upper grove configured for receiving one or more upper teeth (maxillary teeth) of the user, and a lower surface of the bite block provides a lower grove configured for receiving one or more lower teeth (mandibular teeth) of the user. One distance between the lower grove and the oral opening is greater than the other distance between the upper grove and the oral opening, thereby the invention serves to extend forward the mandible and reposition a malposition between the mandible and the maxilla of the user.

Abstract: A method for rendering color imitation on a baking tray comprises steps of: cleaning an inner object-supporting surface and an outer surface of the baking tray and forming a crystalline protective film thereon; oven-drying the cleaned baking tray; spray-coating said surfaces of the oven-dried baking tray with a primer and baking the primer; spray-coating said surfaces of the baking tray with a color paint which imitates a copper or a stainless-steel color and baking the color paint; and spray-coating said surfaces of the baking tray with a transparent non-stick coating and baking the transparent non-stick coating. With the method, surfaces of a baking tray made of a low-priced, carbon-steel or cast-iron substrate can be provided with a color imitating an expensive, fine-textured material such as copper or stainless steel and a non-stick effect.

Abstract: A method for conducting a water transfer printing process on a baking tray comprises steps of: cleaning an inner object-supporting and an outer surface of the baking tray and forming a crystalline protective film thereon; oven-drying the cleaned baking tray; spray-coating the inner object-supporting surface with a silicone and baking the silicone; spray-coating the outter surface with a primer and baking the primer; transferring a pattern onto the outer surface by water transfer printing, wherein a water flow is used to flatten a transfer paper attached to the baking tray; over-drying residual water left from the water transfer printing process; spray-coating the outer surface with a silicone-based transparent varnish and baking the transparent varnish. The present invention allows a baking tray having an irregular shape to be provided with a pattern thereon and thus beutifies the baking tray.

Abstract: A method for manufacturing a patterned baking tray comprises steps of: removing dirt and grease from a first surface and a second surface of an unpainted flat plate; sandblasting said surfaces; spray-coating the first surface with a first primer and baking the first primer; spray-coating the first surface which has been spray-coated with the first primer with a fluorine-containing resin and baking the fluorine-containing resin; spray-coating the second surface of the flat plate with a second primer and baking the second primer; screen-printing the pattern onto the second surface which has been spray-coated with the second primer and baking the printed pattern; and stretch-forming the flat plate into the baking tray having the printed pattern on an outer surface thereof. The method allows a baking tray having an irregular shape to be formed with a pattern thereon and thus beautifies the baking tray.

Abstract: A brush having a brush head of changeable angles includes a handle which has a first connection end on one end with an inclined first end surface and a gripping end on other end, and a brush head which has a second connection end and a bristle end on other end. The second connection end has an inclined second end surface mating the first end surface. The brush head and the handle can be coupled together and swiveled about the axis of the coupling portion. Thus the handle and the brush head can be coupled on a straight line or to form an angle between them. When in use the bending brush head and the handle can be remote from grilling flame to dispense sauce on grilling goods without scorching user's hands.

Abstract: A handle includes a metal frame with a first end and a second end connecting by a pair of opposing upper and lower bridge plates that form a carved out space between them, a wooden base wedged in the carved out space and a pair of wooden side plates formed in a symmetrical shape on the left side and right side that have a selected height and at least one planar surface to be bonded to one side of the wooden base that is exposed outside the metal frame after being wedged. Thereby the handle is formed and consists of the metal frame and wooden base and side plates in an integrated manner.

Abstract: A cooling rack for foods to hold and cool baking foods includes a first holding rack and a second holding rack that are movably coupled with at least two U-shaped legs. The first and second holding racks are grid racks consisting of a plurality of wire rods to form respectively a first platform and a second platform. The first platform of the first holding rack has a plurality of coupling portions on selected locations to engage with the legs. The first platform has one end bent to form a bucking portion. The second platform of the second holding rack has two or more latch lugs on selected locations on a lower side that have respectively an aperture to be coupled with the distal ends of two poles of each leg. The first and second holding racks may be stacked over each other or spaced from each other at a selected distance through the legs.

Abstract: A barbecue basting brush with a changeable brush head consists of an elastic brush head and a handle that are fastenable and detachable with each other. The brush head has a coupling section which has one end forming a notch on one side and another side forming an elastic latch tongue. The handle has one end forming an annular hub to couple with the coupling section of the brush head. The annular hub and the stem of the handle form a juncture which has a retaining block formed on the inner side of the annular hub. The brush head may be inserted into the annular hub from the end where the notch is located. The plane of the notch is in contact with the plane of the handle where the retaining block is located to form a latched bucking to allow the brush head to be inserted into the annular hub for a selected depth and anchored.

Abstract: A lock clamp apparatus is a kind of clamp. It includes a first clip, a second clip and a space between the first, second clips, and a stander to hold objects.
