Abstract: A connector for providing semi-permanent connection between a bus bar and a connector contact is formed by ovelapping a bus bar tab with at least one contact tail of the connector contact and gripping the overlapped bus bar tab and the contact tail with a spring clip. In this manner, the spring clip produces the pressure required to establish adequate contact between the bus bar tab and contact tail. According to another feature, the junction including the bus bar tab, the contact tail and the spring clip are isolated by covering them with an electrically insulating sleeve, this sleeve also serving to retain the spring clip in position.

Abstract: A press-fit bus-bar for distributing power along a backplane or a printed circuit board comprises a number of flat bus bar conductors fabricated from an electrically conductive material. Each bus bar conductor is separated from adjacent bus bar conductors by layers of an insulating material. A number of electrically conductive press-fit tails protrude from one edge of each bus bar conductor. When the laminated bus bar conductors and insulating material layers are placed in a housing which is then filled with a hardened epoxy resin, the press-fit tails protrude from the surface of that epoxy resin. These protruding tails can be press-fit in a backplane(s) or printed circuit board(s) for the purpose of supplying these backplane(s) or printed circuit board(s) with electric power.

Abstract: A device for connecting an electrical contact to a flat bus bar conductor formed with a tab comprises a spring sleeve and a tubular shroud. The sleeve receives both the tab and the electrical contact in order to interconnect these tab and contact. The shroud has a first section in which the sleeve fits and a second section through which the tab is inserted in the sleeve, this second section being slotted to define a seat for the bus bar conductor. The electrical contact comprises a first pair of mutually spaced apart flat contact members, and a second pair of flat contact tails connected to the contact members and spaced apart from each other for insertion in the sleeve with the tab between them. An electrical connector comprises an electrically insulating housing formed with a cavity with front and rear openings, and the electrical contact having its contact members inserted in the cavity through the rear opening to form a conductor-receiving receptacle accessible through the front opening.

Abstract: A means and method of controlling the muzzle velocity of a gun launched projectile to ensure that the muzzle velocities of several rounds of the same type tend towards the same value or that of an individual round approaches some nominal value. A sensor means measures a parameter related to the muzzle velocity of a projectile and a control means instructs an electrothermal energy unit to discharge a fixed amount of energy into the gun barrel after a certain time delay, the time delay being derived from the measured parameter and being such to ensure that discharge causes the projectile to achieve a controlled muzzle velocity.

Abstract: Disclosed is an improved apparatus and method for performing downhole operations to a subterranean formation while isolating the formation from the remainder of the well bore. The invention utilizes a tool assembly which initially sets a packer above the formation while allowing a downhole tool to extend through a passageway in the packer to perform operations such as perforating the formation. The assembly permits retrieval of the tools through the passageway in the packer while sealing off the formation from the remainder of the well.

Abstract: A canopy for truck and trailer loads in which a cover of a sheet of flexible water resistant material is supported by a plurality of inverted U-shaped members pivoted on opposite sides of the load by support members attached to the bed of the truck, trailer or pallet. The U-shaped members and the flexible sheet fold downwardly at one end of the load, thus fully exposing the load, and unfold over the load with the two end U-shaped members in substantially horizontal position extending oppositely from one another and the other U-shaped members being spaced from the end members and from each other throughout the distance between the two end members. A flexible strap interconnects most of the U-shaped members to assist in obtaining the desired spacing of the members in the unfolded position. The lower edges of the cover are secured to the bed or pallet when the canopy is in its unfolded position to hold the cover firmly over the load while it is being hauled by the truck or trailer.

Abstract: A swaging apparatus in which a pusher member pushes a hose coupling sleeve having a hose end portion therewithin downwardly into a die cavity of a closed die defined by mating segmental die members in a retainer to radially deform said sleeve into gripping engagement with said hose characterized in that upward retraction of the pusher member automatically opens the die by effecting upward and lateral separating movement of said die members thus to release the swaged hose-coupling assembly for downward discharge from between the separated die members and through said retainer. The swaging apparatus is further characterized in that before the pusher member commences its downward swaging stroke on the next unswaged hose-coupling assembly inserted upwardly through the retainer and between the separated die members, the latter are released for movement by gravity into mating engagement within said retainer.

Abstract: This invention relates to chemical conjugates of acid polysaccharides and biochemically active complex organic molecules and particularly to such conjugates which are capable of forming soluble sodium salts and insoluble calcium salts.
