Abstract: An apparatus for automatically pivoting a first member relative to a second member comprises a housing connectable to the second member; a shaft connectable to the first member and juxtaposed to rotate about its axis within the housing between a rest position and an open position, the shaft having first and second rates of rotation in a closing direction from the open to the rest position; a torsion spring assembly connected between the housing and the shaft; a dampening assembly connected between the housing and the shaft for exerting a dampening torque upon the shaft during at least one direction of rotation of the shaft relative to the housing; a time delay assembly connected between the housing and the shaft for variably exerting a braking torque on the shaft; a shift assembly connected between the housing and the shaft and operable to enable and disable the time delay assembly; and, a clutch assembly for engaging the shaft with the dampening assembly and the time delay assembly when torque is applied to

Abstract: An apparatus is disclosed for use in assembly and disassembly of the strut assembly having a shock absorber disposed within a coil spring. The apparatus includes a frame and a first spring engagement member secured to the frame for engaging the first end of the spring of a strut. A second spring engagement member is provided connected to the frame for movement with the frame toward and away from the first spring engagement member.

Abstract: An apparatus is disclosed for use in assembling and disassembling a strut assembly of the type having a shock absorber axially disposed within a coil spring. The apparatus includes a frame and attachment members for holding a first portion of the spring with the spring positioned in predetermined alignment within the frame. A compression head is mounted on the frame and movable toward and away from a compression direction. The compression head includes first and second compression elements for imparting a force on a second portion of the spring and urging the spring toward the compression direction. The compression head includes linkage for connecting the first and second compression elements with the elements being movable relative to one another and free to assume unaligned positions as the compression head urges the spring into compression.

Abstract: Working fluid compositions for absorption refrigeration systems comprising alcohol, lithium bromide, zinc bromide and a synergistic mixture of arsenic trioxide and the sodium salt of ethylenediaminetetraacetic acid which are markedly inhibited in corrosion of ferrous metals, and a method for inhibiting the corrosion of ferrous metals by alcohol-lithium bromide-zinc bromide mixture by adding a synergistic combination of arsenic trioxide and ethylenediaminetetraacetic acid.
