Title: Clam shell die cutter
Inventor: TREVISO JOE
IPC: B26D7/26
Filed: 1990-01-24
Abstract: AN IMPROVED CLAM SHELL DIE CUTTER     Abstract of the Disclosure An improvement  is made  to a  die cutting press and to the method  of die  cutting in  a  press  by  providing  two opposing and  oppositely driven  clamping  bars  which  move together to  clamp the  die board and to accurately position the clamped die board at a predetermined location within the press.   The press  is operated to determine the adequacy of the cut  produced by  the die in sheet material fed into the press.   If the  cut is  unsatisfactory, the  opposing clamp bars are  quickly driven  apart thereby  releasing  the  die board.  The die board can be removed from the press and then manipulated or modified to cure any imperfection in the cut.          The modified die board is then reinserted into the press and accurately repositioned at the predetermined location within the press by driving the opposing clamping bars towards each other against  the die  board.   The drive  mechanism of the clamping bars  insures that  when the  die board is securely clamped,  the   die  board   will   always   be   accurately repositioned in  the same  press  at  exactly  the  location assumed by the die board when it was inserted.  The opposing moving clamps  automatically  move  the  die  board  to  the predetermined position  without the  need for  measurement, registration or  concern for variations in tolerances within a jig.

Patent CA-2015623-A1 (CA)
Inventor: LEPAGE JEAN-PAUL
IPC: E05B65/00
Filed: 1990-04-27
Abstract: ABSTRACT OF THE DISCLOSURE           The device comprises a housing attachable to the handle bar of a nestable cart, such as a shopping cart.  The housing has a  front  and  a  back  key  slot, each for receiving a key.  Key locking members are mounted in the housing, each  associated with a  key  slot.    These  locking  members  are interconnected by a position-inverting mechanism, so that when one  locking member is in a key-locking and retaining position, the other locking member is in a  key-releasing  position,  and  vice versa.    A  key is attached to  each housing  by means of a flexible link, such as a chain, long enough to be inserted into the  back key  slot of the housing of  the next  nested cart.  However the flexible link can be longer than this requirement.  The keys are retained  in their back key  slots and  thus the  carts are  interlocked in a nested position.   The key of the frontmost cart is  used to  unlock the latter.   The front  key slot is associated with a coin-receiving slot and  a  coin-actuated  locking  member  release  retains the locking member  of the  front key slot in key releasing position. Upon insertion of a coin in the coin slot and also of  the key of the frontmost cart within its front key slot, said last-named key is retained in the housing of the frontmost  cart and  the key of the  next  cart  is  released  from the same housing, whereby the frontmost cart is released for use;  it must  be returned  to the row  of  shopping  carts  and  the  key  of  the  next cart again reinserted into the back key slot of the returned cart  to obtain release of  the key  of the returned cart and of the coin trapped in its housing.

Patent CA-2019054-A1 (CA)
Title: Stamping tool
Inventor: HILL RONALD C
IPC: B21D28/12
Filed: 1990-06-15
Abstract: ABSTRACT      A stamping tool for use in an auto-indexable tool station having a number of character inserts that can be rotatably moved below a striker area so that a thin metal plate or sheet of metal may be marked.  The stamping tool allows for automatic adjustment of tool length for any variation in material thickness.  A pneumatic cylinder actuates a mechanism that engages the key way in the head nut.  The tool length is changed by the rotary motion of the auto-indexable tool station.  The character housing is rotated by the indexable tool station through the punch key which moves the selected character insert to the striker area within the tool.  The striker area causes the character insert which is spring biased to protrude lower than the character inserts that are not in the striker area.  When the stamping tool is struck by the ram, only the character insert in the striker area will contact the material to be marked.  Further, an overload protection mechanism is included to prevent any tool damage if the tool length is adjusted incorrectly.  A control system provides an automatic sequence cycling of the indexing system to position each required stamping tool in an accurate stamping position.  The tool has capacity for a full alphanumeric set which can be selected automatically through commands in a control program.  These characters can be selected in any order to create a specific identification.

Abstract: ABSTRACT OF THE DISCLOSURE        A method and apparatus is disclosed for direct reduction of metal oxides, using a rotary kiln, fed with greenball pellets, the kiln having a feed-end and a discharge end.  A first chamber within the kiln, and adjacent to the feed-end, is used for drying, preheating and indurating the greenball pellets.  Greenball pellets are fed into the first chamber using a conventional mechanism.  The feed-end is sealed to prevent egress of process gas from the kiln into the atmosphere and ingress of the atmosphere into the kiln.          A first burner is used for drying, preheating and indurating the greenball pellets within the first chamber.   A second chamber within the kiln, adjacent to and connected with the first chamber, having a diameter greater than the first chamber,  is used for reducing the pellets,  the second chamber being adjacent to the discharge end.   A second burner may be used for reducing the pellets within the second chamber.  Reduced pellets are discharged from the discharge end.  The axial angle of the kiln is varied to regulate the flow rare of the greenball pellets from the first chamber to the second chamber.

Title: Leakage control device
Inventor: BLAIR JOHN
IPC: F04D29/10
Filed: 1991-07-09
Abstract: ABSTRACT OF THE DISCLOSURE       A seal enhancement assembly according to the present invention cooperates with the traditional static seals to reduce leakage.  Leakage often occurs along the drive shaft which passes through the static seal.  This is a particular problem in screw pump lift systems used in oil wells.  This leakage problem is reduced by means of a pumping member secured on the drive shaft before the static seal which urges the fluid away from the seal.  Rotation of the drive shaft produces this pumping action and protection of the static seal.
