Abstract: The present invention is directed to methods for enhancing immune responses. Such methods serve to enhance dendritic cell activation, which, in turn, promotes a more robust immune response to foreign antigens. As such, the methods and compositions of the invention are for useful in the context of a variety of prophylactic and therapeutic regimens.

Abstract: Enclosed is a removable fastening assembly (80, 82, 84, 86) that can be secured to and removed from the same side of an opening in an article such as a plate (10) or the like into which an externally threaded member such as a screw ("S") is to be received by compressing opposed spaced-apart contracting means (18, 18', 58, 72) towards each other exposed on the side of the fastener facing away from the article opening (38) to cause a compressible member (16, 16', 56, 68) disposed on the side of the fastener facing towards the opening to contract sufficiently to be received into the opening with at least a portion thereof pressing against opposite sides of the wall of the fastener surrounding the opening with sufficient force to secure the fastener to the article upon release of the compressive force.

Abstract: Disclosed are two embodiments (40, 50) of a self-locking prevailing torque fastener featuring a common base portion (2) having an aperture (4) therethrough for receiving a threaded member that is at least partially surrounded by means such as a warped helical edge (6) for engaging the threads of the threaded member. Fasteners (40, 50) are provided with a pair of spaced-apart resilient torque arms having respective sections (8) that respectively extend downwardly from opposite edge of base portion (2) to sections (10) that extend upwardly to sections (12) that extend through respective openings (14) in each to respective free-ends (16) that are adapted to press against opposite sides of the threaded member.

Abstract: Disclosed is a bolt fastener adapted to rotatably or non-rotatably secure a bolt to a frame through an aperture therethrough. The fastener is provided with a base member having a slot therethrough and a resilient arm that extends upwardly from an edge of the base member and, in spaced relationship, across the side thereof that is to face away from the side of the frame against which the base member is to be laid and then downwardly past an opposite edge of the base member and then inwardly towards a plane generally transverse to the plane of the base member to a free-end thereof disposed in the side of the base member facing towards the frame against which the base member is to be laid to provide an open-ended clip.

Abstract: An apparatus for the removal of particulates from a flowing gas stream and a process for its use are provided. A perforated screen separator formed as a plate having parallel rows of perforations formed by pushing alternating strips of the plate material forward and backward from the plane of the plate is used. The perforated screen separator may be used alone or with a fiber bed mist eliminator for increased particulate removal.

Abstract: A molded, one-piece, self-locking, strain-relief bushing for mounting an electrical conductor to a panel having an aperture through which the conductor passes. The bushing is designed to mount the conductor substantially parallel to the panel on one side thereof and substantially perpendicular to the panel on the other side thereof. The bushing comprises two generally concave complementary portions adapted to be folded together in axially offset position over the conductor. One of the complementary portions is frangibly attached to the other and is adapted to be sheared therefrom for self-locking mounting of the conductor to the panel. The busing may be preassembled by hand and self-lockingly installed by a simple hammer blow.

Abstract: A unitary, permanently-locked, strain-relief bushing and a tool for applying same in an aperture in a support panel. The bushing comprises two generally concave, complementary portions interconnected by a flexible web. Each complementary portion comprises a shank segment having an especially configured shouldered end and a grip segment frangibly secured thereto axially extending from the shouldered end.The tool for applying the bushing into the aperture comprises an open-sided barrel, a plunger within the barrel and an especially configured mounting recess at the front end of the barrel. The mounting recess firmly receives the shank shouldered ends when the complementary portions are folded, concave portion to concave portion permitting an electric conductor or the like to be received in the bore thus defined by the complementary portions.

Abstract: An improved one-piece connector clip for securing a helically grooved flexible electrical conduit within generally round apertures in a junction box is disclosed. The body of the clip comprises a plurality of generally flat sides and is provided with tabs which engage the helical groove in the conduit to prevent the conduit from being pulled out of the clip and to electrically interconnect the clip and the conduit. A collar on the inner end of the clip encloses the end of the conduit to protect the wires contained therein against any burrs which may be present on the end of the conduit. Resiliently deflectable retaining arms and flanges clampingly engage a wall of the junction box to hold the clip and conduit in place and to electrically interconnect the clip and the junction box.
