Abstract: A gas dispersion nozzle for a gun silencer having a nozzle portion with a front end and a rear end and walls enclosing a hollow interior therein. The rear end of the nozzle portion is attached to the gun silencer and the nozzle portion extends into the interior of the gun silencer. The rear end also attaches to a firearm. The walls have channels which direct flow of propellant gases out of the hollow interior and into the interior of the gun silencer at an angle to a path along which the projectile passes when the firearm is discharged. The channels cause the flow of propellant gases to become turbulent or rotational or both and can cause the flow rate of said propellant gases to decrease. The gas dispersion nozzle reduces the report and/or flash produced by the discharge of a firearm.

Some embodiments are directed to improved fluidic connectors or suction adapters for connecting to a wound site, for example using softer, kink-free conformable suction adapters.

Abstract: A casting method includes coupling a mold to a crucible, the mold having one or more part-defining cavities and one or more feed passageways. A first rotating of the crucible and mold pours molten metal from the crucible through the one or more feed passageways into the one or more part-defining cavities. A second rotating of the crucible and mold returns molten metal from the one or more feed passageways, while leaving the part-defining cavities filled.

Abstract: A needle assembly includes a transparent or translucent housing with a fluid inlet and outlet end, a flashback chamber, and a venting mechanism therebetween. The venting mechanism includes a blocking member to control the fluid flow in the venting mechanism so that it flows along the longest path through the vent. Substantially axially aligned inlet and outlet cannulas extend from the housing and communicate with the chamber. A sealable sleeve covers the external end of the outlet cannula. Relative volumes of the cannulas, the chamber, and the sleeve are selected to provide rapid reliable flashback indicative of venous entry with an internal vent positioned within the housing to divide the interior into first and second chambers, with the second chamber being adapted to maintain a negative pressure therein relative to the external environment so as to inhibit leakage of blood from the needle tip on withdrawal from the patient.

Abstract: An article includes a first portion having a first grain pattern and a second portion having a second grain pattern different from the first grain pattern. The article is a cast article such as a turbine engine blade.

Abstract: A dispensing apparatus for dispensing a controlled amount of powder, the apparatus comprising a hopper defining an exit aperture; an Archimedes screw rotatably supported in the hopper and configured to expel powder from the exit aperture; an actuator configured to rotate the Archimedes screw; a cover configured to selectively close the exit aperture; and a clutch arrangement between the cover and the Archimedes screw. Movement of the cover is controlled by the Archimedes screw through the clutch arrangement.

Abstract: Herein are disclosed methods for liberating one or more packaged devices from a packaging web, and a dispenser for performing such methods. The packaging web is separated into first and second waste webs which are co-wound onto a common collection spool.

Abstract: A customizable sports implement system includes a sports implement having an elongate primary shaft and an elongate grip shaft, and a customizing mechanism including length setting and weight components having a plurality of different assembly combinations, each of which may be installed within a cavity formed in one of the primary shaft and the grip shaft to set a playing length and playing weight of the sports implement. The sports implement system is adjustable among a plurality of different customized configurations by swapping different assembly combinations of the length setting and weight components into the cavity. A method of customizing a sports implement system includes adjusting the sports implement system among different customized configurations by swapping combinations of the length setting and weight components for one another within the cavity, and adjusting a length setting state of the length setting component.

Abstract: A post mounting system includes a post and at least one device for mounting to the post. The post includes a first elongate flange and at least one other elongate flange projecting from a proximal edge of the first flange. A portion of the first flange is deformed to facilitate mounting of the device. The device is located at a given position along the first flange. Upon being located in the given position, the device interacts with the deformed portion to resist lateral movement away from the first flange. The device can include a body and projections that define a recess. Remote ends of the projections are spaced from each other by a distance that is less than a lateral width of the deformed portion. The device can be positioned onto the post and receive the deformed portion in the recess to enable mounting of the device.

Abstract: The protective shield apparatus comprises a partition, a collar, a plurality of protrusions, a plurality of securing members. The partition is provided to fill a surface area between the two volumes to be divided, such as, for example, the front seat area and the back seat area. The perimeter of the surface area is engaged by the collar for completely securing the two volumes. The protrusions are fixedly engaged with the collar. Further, the protrusions in operative association with the abutment secure the protective shield apparatus in place. Particularly, the protrusions and the abutment secure a member on alternate sides for securing the protective shield apparatus. The partition can be comprised of multiple sheets of partitions. The multiple sheets of partition are held together by a plurality of securing members. Thus, the protective shield apparatus can be adapted for varying levels of protection by adding another partition and securing the partitions together with the securing members.

Abstract: An apparatus and method are disclosed for providing a fluid communication path to a wound site through a drape. The apparatus comprises a body portion having a lower surface and an upper surface, at least one connection port, at least one suction port and at least one fluid communication passageway between the connection port and the suction port. A connector at an end of at least one tubular conduit is locatable through the drape into an orifice in the connection port to thereby provide a fluid communication path through the drape between the tubular conduit and the wound site.
