Patent number: 5074833Abstract: A method of making an intermediate bulk container having zones (12) for the attachment of lifting loops (20) from a fabric (10) having eight such zones with lifting loops attached to the zones comprises attaching the opposite selvedges (14, 16) of the fabric together and then attaching the base (26) to complete the bag. The zones (12) are arranged in four pairs with a zone (12a) of one of the pairs being adjacent to one of the fabric selvedges (14). The side seam (24) of the bag so made is thus spaced from its adjacent corner. This means that all four lifting loops can be attached to the fabric while it is still in the flat state since no lifting loop has to cross the seam in the finished IBC>. This form of construction lends itself to automatic stitching processes and radically increases speed of production.Type: GrantFiled: February 5, 1991Date of Patent: December 24, 1991Inventor: Charles S. Futerman

Patent number: 5074721Abstract: A hard metal cutting blade comprises a blade body having front and rear faces. The blade body is meant for engagement to a tool head and for rotation about a rotation axis. The blade is moved in a feed direction for the fine machining of bores that extend parallel to the rotation axis. The front face of the blade includes a recessed chip face which defines a cutting edge that has a main blade that is followed by a secondary blade. The main blade is divided into two regions, a first region that is almost flush or slightly inclined with respect to the secondary blade, and a second region which inclines at a greater angle and is spaced further from the secondary blade. An abrasion-resistant hard material coats the blade body. This material is ground away from the chip face, at least in the area of the secondary blade, to provide a radius of no more than 5 .mu.m for the edge of the secondary blade.Type: GrantFiled: April 4, 1990Date of Patent: December 24, 1991Assignee: Mapal Fabrik fur Prazisionswerkzeuge Dr. Kress KGInventors: Dieter Kress, Friedrich Haberle

Patent number: 5064403Abstract: Apparatus for removing meat from the drumsticks of poultry, such as turkeys and chickens, utilizes aligned, tandem cylinders, the first of which urges the second along a guided path, the second carrying a centering cone pusher thereon for receiving the meat end of the drumstick axially thereinto. Transversely moving gates engage the drumstick about the hock knuckle end and the centering cone, upon moving forward under the force exerted by the first cylinder against the second cylinder, pushes the hock knuckle end through and past the closed gates. This places extreme tension on the tendons between the gates and where they are attached to the hock knuckle, causing the tendons to break while the meat is formed into a gatered mass in and adjacent the centering cone. The gates are withdrawn and the second cylinder is activated, causing a rod to project axially through the meat mass and against the meat end of the bone, urging the bone through a guide passageway and normally expelling it from the apparatus.Type: GrantFiled: July 5, 1990Date of Patent: November 12, 1991Assignee: Sterling Manufacturing Company, Inc.Inventor: Stanley E. Elsten

Patent number: 5061141Abstract: A method and apparatus for producing can bodies, wherein blanks are laterally centered after removal from a magazine, are engaged in the center of their rear edge and are transported into a shaping station in which initially the center section of the blank is bent into its final shape. While doing this, a central force and friction lock is produced between a transporting means and the deformed blank to realize reliable guidance of the already partially bent blank. To further transport the blank, it is contacted at its rear edge in the already completely bent region by two lateral transporting devices and is advanced to a seam forming station, while the opposite longitudinal edges of the blank are brought to an adjoining relationship.Type: GrantFiled: March 29, 1989Date of Patent: October 29, 1991Assignee: Fried.

Patent number: 5059164Abstract: In a spiral tube winder, the plies going to the winding mechanism are monitored to make sure that no ply is broken. If any ply breaks, the machine is stopped so that the broken ply does not become entangled in the apparatus, especially in the glue applying portion of the apparatus. The ply break detection system is automatically activated for each ply lane that is in use so that plies can be added while the machine is in operation, with the result that the ply break protection for each such added ply comes on automatically after that ply has been added.Type: GrantFiled: March 15, 1990Date of Patent: October 22, 1991Assignee: Philip Morris IncorporatedInventor: Peter C. Van Davelaar

Patent number: 5056275Abstract: A hydraulic blasting apparatus has an abrasive storage tank disposed operatively between an abrasive recovery tank and a hydraulic pressurized tank. The abrasive storage tank is provided with a first valve openable from the inside of the storage tank to the atmospheric pressure, and also with a second valve to open the connection between the storage tank and the recovery tank and with a third valve to open the connection between the storage tank and the pressurized tank. The pressure in the abrasive storage tank will become the same as the atmospheric pressure by opening the first valve. Next the first and second valve are closed, and after that the third valve is opened so as to drop the abrasive only into the pressurized abrasive tank for a recycle use.Type: GrantFiled: March 23, 1990Date of Patent: October 15, 1991Assignee: Mitsubishi Jukogyo Kabushiki KaishaInventors: Hirokazu Wada, Nagio Minami, Tamotsu Oka
