Title: Method of stamping for aluminum or aluminum alloy sheet
Inventor: OKAMOTO YOSHIO
IPC: C10M105/38
Filed: 1993-03-04
Abstract: ABSTRACT    A method of stamping for an aluminum or aluminum alloy sheet which comprises coating a liquid lubricant which becomes waxy at a cryogenic temperature to the aluminum or aluminum alloy plate, cooling the sheet and applying stamping in a cryogenic temperature region by using a die of a non-cooling structure type, by which formability is improved.  A mineral series or synthetic oil series lubricant is used as the liquid lubricant. Further, a lubricant containing paraffin as the main ingredient and having a viscosity at 40°C of less than 50 cSt or a lubricant containing an ester as the main ingredient, having a pour point from within a range -50°C to -100°C and a viscosity at 40°C of less than 50 cSt is used.  In another forming method, stamping is applied by using a cooling structure type form made of a material not causing transition temperature and in which liquid nitrogen is circulated through the inside of a punch for cooling and is jetted out from upper portion thereof as a forming die, while controlling the die temperature to a range from -50°C to -196°C and controlling the aluminum or aluminum alloy sheet to a range from -50°C to -196°C, by which the formability equal with or superior to that of the steel sheet can be obtained.

Title: A Short Dwell Coater Apparatus
Inventor: CHANCE JAMES L
IPC: D21H23/00
Filed: 1992-01-31
Abstract: A short dwell coater apparatus (10) is disclosed for applying coating material (12) onto a web (W) guided by a backing roll (14). The apparatus (10) includes a coater housing (16) which is disposed in close proximity to the backing roll (14). The arrangement is such that the web (W) guided by the backing roll (14) moves between the backing roll (14) and the housing (16). The housing (16) defines an application chamber (18) which is open towards the web (W) and which extends along the web (W) in a cross-machine direction. The application chamber (18) is connected to a source (20) of coating material (12) such that the coating material (12) is applied to the web (W) during movement of the web (W) past the chamber (18). Thecoater housing (16) has an upstream lip (22) which is disposed upstream relative to the chamber (18) and adjacent to the web (W). The lip (22) defines an upstream coating overflow (24) for permitting excess coating material (26) to flow therethrough. A flexible coater metering blade (28) is disposed downstream relative to the chamber (18). The blade (28) extends from the housing (16) towards the web (W) for metering the coating material (12) applied to the web (W). A perforate conduit (30) is disposed within the chamber (18) and extends in a cross-machine direction. The conduit (30) permits the flow (32) therethrough of a vortex (34) of entrained air generated within the chamber (18) such that in use of the apparatus (10), when the vortex (34) of entrained air is generated within the chamber (18), the air (34) flows through the perforate conduit (30) away from the chamber (18) so thatstreaking of the coating material (12) due to the intermittent escape of the entrained air (34) past the metering blade (28) is inhibited.

Title: Blow-out prevention device for shutting off an annulus between a drill column and a well wall when drilling for oil or gas
Inventor: SANGESLAND SIGBJORN
IPC: E21B21/10
Filed: 1993-10-15
Abstract: Abstract A blow-out prevention device  (4)  for shutting off a annulus  (8)  between a drill column  (7)  and a well wall by means of an expandable sealing device (3) when an unwanted blow-out of fluid and/or gas takes place from a geological unstable well  formation when drilling for oil or gas. When   a   blow-out   takes   place,   a compressive-pulse code is activated in the inlet of the drill column (7) and is transmitted through the drilling fluid to a pressure sensor (25) which trans-mits the compressive-pulse code on to the  microprocessor   (37)   which   is preprogrammed with the pressure code. If the pressure codes coincide, an electric motor (27)  is activated, which, via a set of gears  (30)  and a nut-and-bolt device (32, 33), displaces a valve plate (22)  axially  towards  the  valve  seat (26). The drilling fluid then flows out through the nozzles  (24) and causes a big  pressure  drop  which  is  used  to expand a sealing device (3) so that the annulus (8) is shut.

IPC: A41D13/00
Filed: 1994-02-11
Abstract: A hockey goaltender's pad is described, in which the upper segment of each side roll is sewn with darts which facilitate flexing of the rolls. As the knee is bent, the darts open, thus in effect increasing the length of the outside of the roll in response to the tensile load there, so that the outside of the roll does not restrict the flexing. As the leg is straightened again, the darts close.
