Patent number: 11779969Abstract: An apparatus and process for processing outer surfaces of glass containers (50) for use in pharmaceutical, medical or cosmetic applications, said glass containers (50) having a cylindrical main body (52). The process comprises: providing (S1) a plurality of containers (50); separating individual containers from said plurality of containers (50); and sequentially conveying said individual containers (50) through a processing station (1; 61). In the processing station (1; 61), the individual containers (50) are rotated about a longitudinal axis thereof while outer surfaces of the cylindrical main bodies (52) are in contact with a scrubbing member (27; 30, 35), for reducing an adhesive surface behavior of the outer surfaces of the cylindrical main bodies (52) of the individual containers. In this manner the surface properties of glass containers may be enhanced significantly with a cost-efficient and simple processing to thereby prevent undesired ‘stickiness behavior’ of the glass containers.Type: GrantFiled: November 5, 2019Date of Patent: October 10, 2023Assignee: SCHOTT POONAWALLA PRIVATE LIMITEDInventors: Anil Narayan Narvekar, Pratul Prakash Potdar

Patent number: 5718030Abstract: A dry abrasive delabeling apparatus for both plastic and glass bottles, sometimes called a label stripper, in which the bottles are fed by an in-feed starwheel to a circular starwheel which rotates the bottles slowly. Within the starwheel are wire bristle brushes rotating at a high speed against the bottles to flick off paper, foil, or plastic from the label on the bottle while restraining the bottle in close contact to the ends of the wire bristle by means of a rubber bladder to press against the bottles. The bottles are held against the wire bristles while the bottles are rotated as they are held against the bladder. The debris is vacuumed away from the apparatus.Type: GrantFiled: July 18, 1994Date of Patent: February 17, 1998Assignee: Langmack Company InternationalInventors: Clark B. Langmack, Charles E.

Patent number: 5591069Abstract: An improved ice skate blade sharpening system utilizing a powered rotating grinding wheel. The system has an adjustable guide for preventing canting and twisting of the blade as it is sharpened, and applies a constant cutting pressure to the edge irrespective of the force applied to the skate by the operator. The system also has a dressing mechanism utilizing a diamond-tipped stylus to maintain the proper curvature of the grinding wheel. The grinding wheel has a central plane perpendicular to the rotational axis, and is mounted to a drive shaft of an electric motor attached to a sliding block biased toward a first position by springs. The guide includes two opposing bearing surfaces spaced a distance apart and a mechanism for adjusting the distance between the bearing surfaces. The central plane of the grinding wheel lies between the bearing surfaces.Type: GrantFiled: November 14, 1994Date of Patent: January 7, 1997Inventor: Michael H. Wurthman

Patent number: 5567195Abstract: A method and apparatus for initially taking an individual bar from a supply of bars and placing it on an entry conveyor while preventing movement of the remaining bars. Other mechanisms are provided for adjusting the entry conveyor to accommodate the diameter of the bars to be ground. The individual bars to be ground are initially moved into position between a regulating wheel and a grinding wheel. The regulating wheel maintains the bar against the grinding wheel and the movement of the regulating wheel toward the grinding wheel during the grinding action is sensed by an encoder device. The encoder device in turn signals to a servomotor to move the grinding wheel an amount equal to but in the opposite direction to the regulating wheel to compensate for the wearing of the grinding wheel. The regulating wheel is set at a slight angle relative to the bar to impose a vector force that moves the bar through the grinding station to the exit conveyor from where the bar is subsequently moved to a holding area.Type: GrantFiled: January 10, 1995Date of Patent: October 22, 1996Assignee: Tufts Grinding, Inc.Inventors: Arthur W. Tufts, Mark Jellema, Blair Haddle

Patent number: 5522684Abstract: A portable tool for milling a chamfer edge on a workpiece includes a milling tool mounted on a motorized drive unit. A hood is carried on the drive unit and partially houses the milling tool. The hood has a bottom opening adjacent the path of the milling tool. A V-shaped guide structure is mounted adjacent the hood opening and includes a pair of guide plates spaced to provide an opening for supporting the edge of the workpiece that is to be cut adjacent the cutting path of the milling tool. An internally mounted bracket in the hood supports the guide plates.Type: GrantFiled: October 11, 1994Date of Patent: June 4, 1996Inventor: Philip Heck

Patent number: 5518438Abstract: An apparatus for grinding tapered points on needles is disclosed. The apparatus has a frame and a transport associated with the frame for transporting a plurality of needles. The transport has a predetermined curvature and a feeder is mounted adjacent the frame for feeding needles to the transport. A grinding wheel is disposed adjacent the transport and has a major diameter at a first end and a minor diameter at a second end, the major diameter being greater than the minor diameter and connected by a curved grinding surface the diameter of which increases progressively therebetween. The curvature of the grinding wheel in a first third portion between the major and minor diameters is of greater mean curvature than the mean curvature of the corresponding opposed portion of the transport. A second third portion of the grinding wheel is of greater mean curvature than the mean curvature of the corresponding opposed portion of the transport.Type: GrantFiled: October 8, 1993Date of Patent: May 21, 1996Assignee: United States Surgical CorporationInventors: Marcelino P. Munoz, W. Scott Samsel, Eugene P. Cybart, Jr.

Patent number: 5480345Abstract: This invention relates to a knife sharpener and more particularly to a knife sharpening device wherein the knife is clamped in a fixed position on a table or platform and the knife sharpening or grinding device is moved along the edge of the knife to be sharpened. The knife sharpening or grinding device is clamped into an adjustable arm which is attached to a roller. The roller slides along a track formed in the table or platform which has the identical configuration as the knife blade. Therefore, the edge of the sharpener or grinding device is maintained in constant contact with the edge of the knife during the sharpening. This prevents the problem of knives being sharpened unevenly and inaccurately, as is often seen in conventional knife sharpening methods.Type: GrantFiled: June 6, 1994Date of Patent: January 2, 1996Inventor: Bobby J. Bethea

Patent number: 5468173Abstract: An automatic deburring machine used for the edge deburring of hard components. This automatic deburring machine, utilizing several abrasive flap wheels, causes the wheels to penetrate the internal and external edges by combining the three axis motion of the abrasive flap wheels with the two axis motion of the work piece transporting system. This multi-axis motion will significantly deburr the internal and external edges with three hundred and sixty degrees of symmetry.Type: GrantFiled: September 30, 1993Date of Patent: November 21, 1995Inventor: George R. Winton, III

Patent number: 5397262Abstract: An improved knife grinder is desinged to have a motor transmission axle which transmits one or two units of wheel axle with its angles which are facing one another and entend slightly upward and outward. A base is fixed onto the vertical bottom surface which extends from the wheel shaft in coordination with the bearing positioning wheel axle, onto the upper end of which an axle bush can be housed. One or two units of glaze wheel is fitted onto the outer edge of the axle bush. While a stripe column is housed onto the position which is corresponding to the axle bush at its interior. Extending outward from the glaze wheel, three layers made of such materials as plastic, foam and grinding cloth are formed. A stair face is set on the upper end of the plastic layer, into which a positioning cover can be housed, and its mutli-angled protrusive column will be housed into the axle bush positioning hole; while the multi-angled groove at the other end will allow the wheel axle to be tightly screwed by a scew nut.Type: GrantFiled: July 8, 1993Date of Patent: March 14, 1995Inventor: Chuen-Cherng Lii
