Abstract: A basket-style carrier having a top panel for enclosing the carrier. The top panel comprises flaps (46, 48) foldably connected to the side panels (12, 14) which contain openings (56) through which a top portion of the articles (B) packaged in the carrier extend. The flaps also include at least one fold line (50, 52) extending parallel to the side panels, allowing the flaps to be folded over so that their free ends (54) extend to and contact the center partition (30) of the carrier. This biases the top panel flap edges against the center partition and an edge of the opening against the underside of flanges or other transversely extending projections (F) of the articles packaged in the carrier. The handle in a center partition (30) may be designed as a three-ply reinforced handle (30, 80, 122).

Title: Surgical instrument for impact insertion of an intraosseous trocar-needle
Inventor: WAISMAN MARC
IPC: A61M25/06
Filed: 1994-11-04
Granted: 2003-04-15
Abstract: A surgical instrument serves to insert a trocar needle into the bone marrow of a patient for connection of a syringe, an infusion set or the like. The instrument includes a cylindrical housing containing a sliding bolt and the trocar needle configured to bra forcefully shot through the bone material into the marrow by release of a compressed helical spring. The bolt holds the rear end of the needle in a releasable grip permitting the needle to be released and to remain in the bone. The helical spring is positioned in the rear of the housing and of the bolt and is held in com-pressed state by a catch which is releasable by pressure on a trigger. This shoots the bolt and the needle forwards, a collar in the housing stopping the bolt sharply and allowing to needle to be released from the device after its, penetr-ation and to be connected to a syringe or an infusion set for intraosseous injection, infusion or other treatment.

Abstract: A concrete wallform section is made up of at least two connected panels which cooperate to form a concrete engaging face. The panels are joined adjacent the concrete engaging face by a continuous mechanical hook and slot arrangement, which itself is maintained by cooperating connected flanges of the panels. The flanges and the hook and slot arrangement form a box-like cell at a junction of the two panels. A concrete wallform system according to the invention utilizes individual extended panels which are interconnected to form wallform sections. The width of the wallform sections can be increased by adding an intermediate panel or panels. This simplifies manufacture and allows convenient repair, replacement or salvaging in the field.

Title: Roofing washer magazine for barbed roofing washers
Inventor: LARSON PAUL M
IPC: B25B23/06
Filed: 1996-02-13
Granted: 2000-01-04
Abstract: Abstract In a washer-dispensing machine, a chute open at a lower end receives a stack of roofing washers of a type having a central aperture to receive a fastener shank and possibly having downwardly extending barbs.  A shuttle engages a single washer from the stack, displaces the single washer to a separated position as the shuttle is moved from a displaced position to a normal position, and releases the single washer in the separated position as the shuttle next moves from the normal position to the displaced position.  A known mechanism is employed for moving the shuttle between the displaced position and the normal position.  A novel mechanism is mounted operatively to the chute for supporting the stack so as to prevent any of the washers in the stack from dropping through the lower end of the chute and for releasing the stack so as to permit a lowermost washer in the stack to drop through the lower end of the chute.  A preferred embodiment includes two stack-supporting fingers and two finger-moving plates, each finger-moving plate coacting with one of the stack-supporting fingers and coacting with a shuttle-moving mechanism so as to support and release the stack appropriately as the machine is operated.  An alternative embodiment includes two pivotably mounted, stack-supporting fingers coacting with a shuttle-moving mechanism so as to function similarly.

Abstract: A method for causing adherence of a web to a drying wire so as to prevent the effects of centrifugal forces and of other air-flow phenomena,  which effects attempt to separate the web from the drying wire in dryer groups having a single-wire draw and arranged in a multi-cylinder dryer of a paper machine.  The dryer groups include heated drying cylinders, a drying wire for pressing the web against outer cylinder faces of the drying cylinders, and guide cylinders or rolls on which the web runs on the outside face of the drying wire.   The guide cylinders have perforations which pass through the cylinder mantle and open into an inside space in the interior of the guide cylinders which is subjected to a vacuum.          The vacuum in the guide cylinders is transferred to the outside face through the perforations.  The guide cylinders have shafts on which the guide cylinders are mounted revolving.  The vacuum level in the guide cylinders is regulated by means of the air quantity in compliance with the threading/running stage and/or running speed and/or with any other process or running parameter of the dryer section of the paper machine so that the effect of the vacuum is sufficient to keep the web in reliable contact with the drying wire.
