Abstract: An improved, easily cleanable folding pan with a continuous cooking surface includes a pair of pan sections with generally planar cooking surfaces joined at the perimeter in side-by-side relationship by a pair of upstanding hinges. The hinges permit pivotal movement of the pan sections from a generally flat cooking position into a folded position for cleaning or storage. The fold margin of one of the pan sections slightly overlaps the fold margin of the other cooking surface, so that in the cooking position the pan presents a continuous cooking surface. The fold margin of one of the cooking surfaces may include a dependent lip for overlapping the fold margin of the other cooking surface when the pan is in the cooking position. A pair of opposed, upstanding handles may be coupled with the perimeter margin of the cooking surface. The perimeter margin of the pan section may be surmounted by an upstanding sidewall.
Abstract: A padlock cover assembly for use in latching and locking doors includes a cover with a peripheral wall. The cover is pivotally mounted to a pivot base which is pivotally mounted to a first door member by a pivot pin. The cover is pivotal relative to the pivot base into and out of covering relationship with a padlock supported by its shackle on a padlock mounting bracket secured to the second door member. A pawl is formed on the cover and sized and positioned such that the pawl is advanceable between the shackle and an upper surface of a padlock body when the cover is advanced into covering relationship with the padlock supported on the mounting bracket in an unlocked condition. The cover is then pivotable about the pivot pin such that a portion of the peripheral wall of the cover engages a bottom of the padlock body advancing the padlock body toward the shackle and into a closed condition.
Abstract: A low profile and removable set screw for use in connecting one medical implant to another and for similar uses.
