Abstract: ABSTRACT A  single  handle-actuated  lid  opening,  closing, and locking mechanism for a large capacity pressure cooker   having   an  open-top  cooking  vat  and  a counter-balanced lid shiftable vertically between  a vat open and a vat closed position.  The mechanism comprises  a  pair  of  slotted  hook  arms  mounted  to either  side  of  the  vat.   A  cam  bar  extends transversely of the vat lid and is provided with a forwardly extending arm near each of its ends.  The forward  ends  of  the  arms  are  joined  by  a  bar constituting a handle in parallel spaced relationship to the cam bar.   The  ends  of  the cam bar  support rollers  receivable  within  the  slots  of  the hook arms.   The  cam  bar  is  manually  shiftable  by  the handle between a forward lid locking position and a rearward unlocking and lid engaging position. In its forward lid-locking position, the cam bar assumes an over-center  orientation  with  its  rollers  bearing upwardly against the upper surfaces of the hook arm slots and the cam bar body bearing downwardly against the lid.   In its rearward unlocked and lid engaging position, the cam bar is rigidly coupled to the lid so  that  upward  and downward  forces  applied to the handle  result  in vertical  upward  and  downward movement of the lid between its vat open and its vat closed positions.  A cam bar lock precludes unlocking and opening of the lid when the vat is pressurized.

Granted: 2000-10-03
Abstract: A catheter assembly is provided with a needle guard that slides slang the needle to shield the distal tip of the needle after the needle is withdrawn from a patient.      The needle passes through an aperture at the distal end of the needle guard, To prevent the backflow of blood through the aperture and onto the needle guard, a gasket is formed in the aperture about the needle. The gasket is formed with the needle in place by filling the aperture around the needle with adhesive. After the adhesive has substantially cured but before the adhesive has tightly bonded to the needle the needle guard is moved along the needle to prevent bonding of the adhesive to the needle.      The needle guard will thereafter slide along the needle with the needle passing through the formed-in-place gasket,

Title: Drink through container lid
Inventor: BOLLER PETER K
IPC: B65D17/40
Filed: 1992-03-19
Granted: 1996-11-12
Abstract: A drink through container lid of the type formed from thin thermoplastic material and which is used as a closure cap on open mouthed beverage cups is disclosed.          Conventional lids of the foregoing description include one or more lines of weakness in the main body portion of the lid and which in part define the drink through segment of the lid.  Normal breakage of this segment is initiated by hand at a location on the bottom of the skirt, which may or may not also include a lift tab projecting outwardly from the  bottom  of  the skirt.    In  accordance  with  this invention, the lift tab is positioned above the bottom of the remainder of the skirt, and proximate to that portion of the outer wall of the groove of the lid which is in frictional engagement with the beverage cup to which it is attached.  By locating the lift tab close to the area of frictional engagement of the lid to the cup, less force is required  to  initiate  fracturing  of  the  thermoplastic material in this area, and reduces the likelihood of the entire lid becoming separated from the container to which it  is  attached when  only separation  of  the  removable segment  is  desired. Means  for  further promoting the fracturing of the material can also be located at opposite ends of the lift tab.
