Abstract: An improved anchor socket and jig assembly for holding implements in concrete is provided which facilitates assembly of the socket element on the base member of the jig assembly and which affords substantially expanded adaptability of the jig for varied size implements and avoids the need for bolts or other extraneous means to secure the socket member to the rail member.The improved jig assembly comprises a longitudinal base member preferably of substantially rigid plastic composition which is provided with locator openings which fit one of the feet of the socket member and, cooperating therewith, a mating turn slot. Both the openings and the turn slots are formed to accommodate the feet of the socket member. The assembly of the socket in the base member in a secure position is readily effected by positioning the socket member between the rails of the base member and locking the two by a manual quarter turn rotation of the socket member in the base member.
Abstract: A hydraulic control system for a four-wheel drive torque transfer mechanism for a vehicle, including an automatic transmission, a transfer mechanism having a two-wheel drive direct-coupling gear (H.sub.2), a four-wheel drive direct-coupling gear (H.sub.4) and a reduced-speed four-wheel drive gear (L.sub.4) and a hydraulic control circuit for controlling the transmission and the transfer mechanism. The transfer mechanism includes a reduction gear mechanism, a first output shaft, a second output shaft connected to the first output shaft by means of a linkage, a four-wheel drive clutch for rotatably connecting and disconnecting the first and second output shafts, a direct-coupling clutch for connecting and disconnecting the input shaft of the reduction gear mechanism and the first output shaft and a reduction brake for shifting the reduction gear mechanism into the reduced-speed mode.
Abstract: A barrier is constructed from a plurality of cell-like elements interconnected to form a rigid barrier under normal circumstances. The linkages between cells provides a friction-brake force which is exceeded upon application of a traumatic force such as a bomb blast. The linkages includes slots in each cell connecting adjacent cells with prestressed nuts and bolts to permit sliding relative movement between adjacent cells after a predetermined threshold force has been exceeded. A transverse reinforcing rod, having a series of plates along its length, passes through adjacent cells. The plates act as a viscous damper as they move through a filler material within the cells while the rod adds strength. The cells may be coated with a dry lubricant to control the static coefficient of friction. The ability of the cells to move protects the barrier from structural failure by dissipating the blast forces through the frictional work required to displace the cells.
