Title: Method of manufacturing a cooking utensil
Inventor: GALLE ALFRED
IPC: A47J27/00
Filed: 1992-07-29
Abstract: ABSTRACT OF THE DISCLOSURE           A method of manufacturing a cooking utensil comprising a round container for the food.  The container comprises a container, a plate made of heat-conducting material and a cap enclosing the plate, the cap being made from a sheet-metal disk and having a base provided with a convex curvature towards the container and also having collar which bears against the round container in a curved transition region between the container base and the container jacket.  The container and the cap are made of stainless steel.  The plate is intermetallically bonded to the container base and the cap.    The plate, the sheet-metal disk and the container base are centered and connected by a central spot weld, using electric resistance welding.  Next, the intermetallic bond is produced by single or multiple impulse pressure and permanent deformation and the cap collar is formed on the sheet-metal disk and its rim is placed around the container.  Use is made of a sheet-metal disk having an edge which, during the shaping of the cap collar, is permanently deformed and pressed against the container.  The sheet-metal disk, the plate and the con-tainer base are centered by the resistance welding so as to be resistant to impulse pressure.  The pulse pressure is exerted so as to produce the convex curvature in the cap bottom.    During impulse pressure, the air is first expelled from the region between the sheet-metal disk and the cap collar in process of formation.  During and after this process, a seal is produced in the form of permanent deformation with regard to the plastic deformation of the plate material.

Title: Exiting paper deflector apparatus for an image reproduction machine
Inventor: RUCH MARK H
IPC: B65H29/22
Filed: 1993-04-06
Abstract: EXITING PAPER DEFLECTOR APPARATUS FOR AN IMAGE               REPRODUCTION MACHINE                ABSTRACT OF THE DISCLOSURE     An  image  reproduction machine  has  an  outlet opening through which successive image-imprinted paper sheets are forwardly discharged by a spaced series of exit roller sets.  The discharged sheets are delivered into  an  open-topped  housing  well  area  having  a horizontal bottom surface with a back edge forwardly and downwardly offset from the outlet opening, and a ramped surface extending downwardly and rearwardly from the horizontal surface back edge.   A deflector bar adjacent  the  outlet  opening  has  first  downwardly projecting portions that engage each discharging sheet and temporarily corrugate and stiffen it in a manner assuring that its front end portion will forwardly clear the rear horizontal surface edge before bending down  to  its  level.    These  downwardly  projecting portions are interdigitated with the exit roller sets and positioned to perform their temporary corrugation function without crinkling the discharging sheets. The deflector bar is also provided with second downwardly projecting portions that function, as the stack nears its  maximum  height,  to  cause  each  successive discharging sheet to engage the previously discharged sheet in a manner forwardly advancing and staggering the uppermost sheets. This reduces the effective stack height adjacent the outlet opening to thereby permit a greater number of discharged sheets to be stacked in the well before the stack blocks the external sheet discharge path.  A notch in the deflector bar serves to receive and protect the pivoted paper output sensor portion of the machine as the stack is removed from the well.
