| 20100034587 | Vibratory Percussion Rammers and Methods of Making Vibratory Percussion Rammers - Vibratory percussion rammers and methods of making vibratory percussion rammers are provided. In one example, a vibratory percussion rammer includes a gear box, a percussion delivery unit extending downwardly from the gear box, and one or more slide bearings disposed in the percussion delivery unit between adjacent surfaces of reciprocating metal components. The slide bearings include a sheet of non-metal material that is curved into the shape of a tube having a C-shape in cross section. Slide bearings according to this design can be disposed in the percussion delivery unit to eliminate some or all of the metal-on-metal contact between reciprocating components, including between the ram and shaft assembly, spring box and the guide cylinder, the spring separator and the spring box, and the shaft of a ram and shaft assembly and an upper end of the spring box. | 02-11-2010 |
| 20110116867 | Vibratory Percussion Rammers and Methods of Making Vibratory Percussion Rammers - A vibratory percussion rammer includes a gear box, a percussion delivery unit extending downwardly from the gear box, and one or more slide bearings disposed in the percussion delivery unit between adjacent surfaces of reciprocating metal components. The slide bearings are made from a sheet of plastic material that is curved into the shape of a tube having a C-shape in cross section and define an open seam extending the entire length of the slide bearing. Slide bearings according to this design can be disposed in the percussion delivery unit to eliminate some or all of the metal-on-metal contact between reciprocating components, including between the ram and shaft assembly and spring box and the guide cylinder, the spring separator and the spring box, and the shaft of a ram and shaft assembly and an upper end of the spring box. The seam width of any slide bearing is wider than the anticipated width-wise thermal expansion of the slide bearing during normal operation. When a plurality of slide bearings are used, the slide bearing that is the easiest to replace has a seam selected to close and fail at a temperature in excess of normal operating temperature that is lower than the excess temperature leading to failure of other slide bearings. | 05-19-2011 |

| 20100059401 | Blister package having a securement mechanism and a method of forming and filing said blister package - A blister package and a method of forming and filling the blister package are disclosed. The blister package includes a first member having a 3-dimensional bubble and a peripheral flange. A major portion of the peripheral flange is folded to create at least one channel and a minor portion of the peripheral flange has a hook hole formed therethrough. A securement mechanism is formed with the minor portion of the peripheral flange which permits the blister package to be opened and closed. The securement mechanism includes a hinged tab and first and second cooperating attachment members. The blister package further includes a second member sized and configured to be slideably received within the at least one channel when the securement mechanism is in an open position. The second member is retained within the at least one channel when the securement mechanism is in a closed position. | 03-11-2010 |
| 20100155285 | Blister package having a securement mechanism and a method of forming and filling said blister package - A blister package and a method of forming and filling the blister package are disclosed. The blister package includes a first member having a three-dimensional bubble, a peripheral flange having a major portion and a minor portion, and at least one area bounded by a perforation line which is capable of being broken. The major portion is folded to create at least one channel and the minor portion has a hook hole formed therethrough. A securement mechanism is formed with the minor portion. The securement mechanism includes a hinged tab and first and second cooperating attachment members. The blister package further includes a second member sized and configured to be slideably received within the at least one channel when the securement mechanism is in an open position. The second member is retained within the at least one channel when the securement mechanism is in a closed position. | 06-24-2010 |
| 20100258464 | Magnetic storage device and a method of assembling the device - A magnetic storage device and a method of assembling the device are disclosed. The magnetic storage device includes a tray, a base and a magnetic member. The tray has a lower surface with a hollow area, and an upper surface. The upper surface has an upwardly extending member with a plurality of cavities formed therein. Each cavity is configured to enable one of a plurality of products to be at least partially retained therein. The base is designed to engage with the tray to completely enclose the hollow area. The magnetic member is sized and configured to be positioned within the hollow area. The magnetic member is capable of exerting a magnetic attraction to temporarily retain the plurality of products in the cavities and exerts a magnetic attraction through the base to releasably attach the magnetic storage device to a magnetically attractive surface. | 10-14-2010 |
| 20120037537 | Magnetic storage device and a method of assembling the device - A magnetic storage device is disclosed which is capable of retaining a plurality of articles, each having a thickness and a magnetic affinity. The storage device includes a base having a cavity which houses a magnetic member and a tray which mates with the base to enclose the magnetic member. The tray has a plurality of cavities formed in an upper surface and each of the cavities is designed to retain one of the articles. Each of the cavities has an elongated, semi-circular configuration with opposite ends located adjacent to a pair of raised abutments. The pair of raised abutments extends to a height less than the thickness of each article. The storage device also includes a cover which can be secured to the tray to enclose the plurality of articles therein. A method of assembling the magnetic storage device is also disclosed. | 02-16-2012 |
