Abstract: Device and method for treating mammalian bone deficiencies, defects, voids and conformational discontinuities produced by congenital deformities, osseous and/or soft tissue pathology, traumatic injuries and functional atrophy is described. The device is a one piece molded body member composed of four substances, each of which contributes to the device, a specific requirement (or requirements) for osteogenesis and/or osteoneogenesis. Taken as a whole, the functions of these device constituents are integrated into a single body member which, when implanted into a bone defect, has the capacity to restore functional architecture and mechanical integrity, initiate osteoinduction and osteogenesis, and maintain the biological process of bone formation and remodeling while the host organism is simultaneously biodegrading the body member.

Abstract: An apparatus (10) is disclosed including a friction clutch (12) and an overload apparatus (14) connected in parallel between an input (16) and an output (18). Encoders (20, 22) are provided for separately detecting the rotational positions of the input (16) and the output (18). A microcomputer controller (580) controls actuation of the friction clutch (12) and the overload apparatus (14) in response to the rotational positions detected by the encoders (20, 22) allowing the clutch (12) to bring the output (18) to be generally aligned with a select rotational position of the input (16) at which time the overload apparatus (14) can be actuated to rotatably relate the input (16) and the output (18) at the select rotational position and actuation of the clutch (12) can be removed. The microcomputer controller (580) also removes actuation of the overload apparatus (14) when the encoders (20, 22) detect rotation of the input (16) relative to the output (18) from the select rotational position.

Abstract: An apparatus (10) for erecting collapsed, tubular cartons (12) is disclosed including a device (32) for removing the top carton (12) of a vertical stack of cartons (12) in a hopper (26) and moving it in a horizontal orientation to an operative position. In the operative position, the second side panel (16) of the collapsed carton (12) underlies at least the first end panel (18) which is in a linear arrangement with the first side panel (14). Suction cups (76) carried by a frame (74) are secured to the second side panel (16) in an attachment position and moved by a parallelogram linkage to an open position located vertically below and coinciding with the first side panel (14). In a first preferred form, the folded closure flaps (22-25) are held by a tape piece (116) applied by a taping machine (114) carried by the last tucking arm (106).

Abstract: A large umbrella includes a plurality of ribs and stretchers and a connecting piece mounted to a mediate section of each rib for connecting the rib and associated stretcher. The connecting piece is substantially U-shaped and has a base section with two ends and a lateral wall extending from each end of the base section. A protrusion projects from an inner side of each lateral wall to form a pair of aligned protrusions adjacent to the base section for securely engaging with the rib. A pair of aligned holes are formed in the lateral walls adjacent to the distal ends of the lateral walls for allowing riveting of the stretcher.

Abstract: An apparatus (10) for preventing theft of riding saddles (12) includes a one-piece, rigid lock device (34) and a padlock (36). The lock device (34) is formed by a finished steel rod having one end bent into a circular shape to form a ring (40) having an extension (42) integrally secured and extending therefrom. The ring (40) is of a size for placement around the saddle horn (16) and for abutment with the saddle body (14). The extension (42) extends through the opening (20) in the saddle body (14) when the ring (40) is received on the saddle horn (16) and adjacent to a bar (28) of a saddle rack (22). A series of apertures (44) are formed in the extension (42) for slideable receipt of the legs of the clasp (38) of the padlock (36). Additionally, the clasp (38) of the padlock (36) extends around the bar (28) of the saddle rack (22) to anchor the lock device (34) to the saddle rack (22).

Abstract: A relief grinding device (100) is disclosed including a flange assembly (106) slideably mounted on and rotatable with a grinding shaft (18) which is mounted on the free ends of pivot arms (14) pivotally mounted to a table (12). A grinding wheel (108) is mounted to and rotatable with the flange assembly (106). A back relief housing (114) is rotatably mounted to the flange assembly (106) and held at an adjustable angle on the grinding shaft (18) by a back relief restraint (124) adjustably secured thereto and slideable on a support shaft (102). A stop (134) for abutting with the first face of the blade is mounted to a holder (128) slideably mounted to a mount (122) of the back relief housing (114). A guide finger (138) for abutting with the opposite face of the blade is slideably mounted to the holder (128) and a holding block (136) secured to the stop (134).
