摘要:
The device is for grinding a pipe from an inside. The device has a spindle arranged to be rotated. The device further has protrusions fastened to the spindle. The protrusions have a strip causing an elastic force when being bent. The protrusions are arranged to position the device or a part of the device inside the pipe. The protrusions have blades arranged to grind the inner surface of the pipe, while the spindle is being rotated.

A pipe cleaner assembly is provided for facilitating removal of burrs and debris from an interior surface of a pipe. The pipe cleaner assembly includes an elongated core having a first end and a second end. The first end is configured for attachment to a power tool to selectively rotate the core. A plurality of bristles is provided. Each bristle has a base coupled to the core between the first and second ends. The base of each bristle is coupled to the core so that a free end of the bristle extends from the core. The bristles are aligned along a length of the core.

A method and apparatus is provided for cleaning and shaping a probe tip using a multi-layer adhesive and abrasive pad. The multi-layer adhesive and abrasive pad is constructed on the surface of a support structure, such as a silicon wafer, and is made of an adhesive in contact with abrasive particles. Adhesive is applied in layers with abrasive particles in-between each layer of adhesive. Abrasive particles may vary in size and material from layer to layer to achieve cleaning, shaping and polishing objectives.

An apparatus (46) for reconditioning a protective surface (30) of an optically-read digital recording disc (20) includes a turntable (48) configured to receive the disc (20) and a first motor (52) for rotating the turntable (48) and the disc (20). The apparatus further includes a buffing element (122) and a second motor (54) for rotating the buffing element (122). A timing element (56) synchronizes the first and second motors (52, 54) to substantially simultaneously cease rotation of the turntable (48) and the buffing element (122) following removal of an amount of material from the disc (20). The buffing element (122) includes a foam pad (124) having a discoid portion (126) and an annular portion (128) encircling a perimeter (132) of the discoid portion (126). The annular portion (128) is more resistant to compression than the discoid portion (126). A buffing pad (82) is in fixed relation with the foam pad (124). The discoid portion (126) and the annular portion (128) are configured to cause the buffing pad (82) to impart a substantially uniform buffing force against the protective surface (30) of the disc (20) to uniformly recondition the protective surface (30).
摘要:
An illumination device for use in surgery on the human body has a optical fiber which terminates distally in a bullet-shaped tip. The tip has an exterior surface which is a surface of revolution of a predetermined curve about the longitudinal axis of the tip, the predetermined curve having a first proximal segment, a second intermediate segment, and a third distal segment. The first segment has tangents substantially all of which make less than a first predetermined angle with the longitudinal axis. The second segment has tangents substantially all of which make angles with the longitudinal axis which are greater than the first predetermined angle and less than a second predetermined angle. The third segment has tangents substantially all of which make angles with the longitudinal axis which are greater than the second predetermined angle. A method of manufacturing the tip is disclosed as well.
摘要:
Surface anomalies on pipe are removed preparatory to corrosion coating. The removal is conducted by brushing with wire brush elements or COMAX brush elements which may rotate about axes parallel to the pipe axis or substantially radially off the pipe. Both kinds of brush elements may be used in combination. Before subjecting the pipe to brushing, the surface is particulate blasted to remove ferric oxide and better expose surface anomolies. After wire brushing, the surface is again particulate blasted to provide an anchor pattern of indentations promoting adhesion of the coating.
摘要:
A honing machine for rods of stepwise varying diameters having sensors for sensing the diameter and controlling magnetic valves for hydraulically moving the honing members into and out of engagement with a workpiece. The sensors are contact-free magnetic circuits, the reluctance of which depends on the degree of proximity of a workpiece so as to variably couple a current source to circuits for actuating the valves.

A polishing brush (1) includes a rod-shaped member (2) and a grinding element bundle (4) formed of a plurality of wire-shaped grinding elements (3). The rod-shaped member (2) has a holding hole (6) at a front portion (2a) to hold the grinding element bundle (4). The holding hole (6) has a bottom face (7) and a sleeve-shaped peripheral wall (8) extending from the bottom face (7) in an inclination direction (S). The grinding element bundle (4) has a seated portion (4a) seated in the holding hole (6) and a protruding portion (4b) protruding from an opening (6a) of the holding hole (6) in the inclination direction (S). The tip end of the protruding portion (4b) is located on the outside of the rod-shaped member (2) when viewed from the axis (L0) direction.
摘要:
A device used for cutting a pipe from an inside. The device has a spindle arranged to be rotated. The device further has protrusions fastened to the spindle and arranged to position the device or a part of the device inside the pipe. The protrusions have at least one blade arranged to machine material off the inner surface of the pipe to cut the pipe while the spindle is being rotated.
摘要:
A tip of a capillary used for microinjection is polished on a plurality of sides by using a polishing plate having a surface roughened by dry etching. A first side of the tip is placed on the polishing plate at a predetermined angle and with a predetermined amount of pressing. The polishing plate is repeatedly moved at a predetermined speed by a predetermined distance such that the first side is polished. The capillary is then rotated around an axis thereof to obtain a second side of the tip, and the process of polishing is repeated for the second side.
