  • Patent number: 4832354
    Abstract: A convertible carrier for infants and small children is adjustable to alternative stroller and car seat configurations. The rear wheels of the carrier are mounted on levers which pivot relative to a frame supporting a contoured shell of the carrier. A telescoping handle, mounted pivotally to the levers at points spaced apart from the rear wheels, can be pushed or pulled to pivot the levers, to position the rear wheels in respective operative and storage (car seat) positions. The forward wheels of the carrier can be rotatably mounted directly to the frame. Alternatively, the front wheels can be mounted to the frame through forward levers which pivot on the frame, and are associated with the rearward levers through linking rods, whereby pivoting of the rearward levers causes a corresponding pivoting of the forward levers between operative and storage positions.

  • Patent number: 4832322
    Abstract: An apparatus is disclosed for automatically welding sheet metal panels to form part of a revolving drum for concrete transit mixers. The apparatus includes a fixture having an annular central core, linear and generally longitudinal ribs extended away from the core, and circumferential ribs extended radially outwardly of the core. The ribs intersect to define compartments in the fixture which are closed when the sheet metal panels are placed on the fixture. The compartments are then evacuated, creating a pressure differential to fix the panels on the fixture. A welding carriage is slidably supported on a rail above the fixture. The fixture can be tilted to selectively align panels along the rail for welding linear seams. Circumferential seams are welded by rotation of the fixture while the carriage is held stationary. To more positively maintain the panels in place during welding, compartments along the interfacing edges of adjacent panels are subjected to a higher vacuum.

  • Patent number: 4831933
    Abstract: An explosive detonator consisting of an integrated circuit chip having a silicon substrate on which is formed an amorphous or polysilicon bridge, the bridge extending between two metal wire-bonding pads also on the substrate. The integrated circuit chip is disposed in close proximity to a primary charge such that when the bridge is energized by an electric current, it heats to the point where the charge is ignited. By back-etching the silicon substrate under the bridge, parasitic heat conduction is avoided. Further, by bonding a pyrex tube to the chip with the tube's bore surrounding the bridge, it is possible to pack the bore with an explosive train in fabricating the detonator assembly.

  • Patent number: 4829250
    Abstract: A system for determining the relative orientation in three dimensions between a fixed frame of reference and an unconstrained object. Mutual coupling between three orthogonally disposed transmitting coils driven by a multifrequency source and three orthogonal receiving coils produce sets of analog voltages which are sampled; digitized and processed using a fast fourier transform device to yield directional components for determining the pitch and yaw angles about a line-of-sight axis. By using a multi-frequency source to drive the transmitting coils and by deriving coordinate component measurements to at least two discrete frequencies, errors in the results due to eddy currents in surrounding conductive structures can be compensated for.
