The bed frame of a sofa-bed is resiliently supported within the sofa frame by spring suspension assemblies on each side of the frame. Each spring suspension assembly includes a first mounting bracket attached to the sofa frame, a second mounting bracket attached to the bed frame, and a resilient support between the first and second mounting brackets.

An electrically releasable safety ski binding in which a measuring system determines the load applied to a skier's leg during skiing and a release mechanism incorporating an electromechanical converter such as a solenoid acts on a clamp device securing the ski boot to the binding to release the ski boot when the aforementioned load reaches a dangerous level. To prevent the binding becoming inopera...

A mold for forming elastomeric articles and the like, has vent plugs inserted in bores through the body of the mold. The vent plugs may be manufactured of sintered metal. Each vent plug has a bore therethrough that is significantly smaller than the bore through the mold body, so that very little, if any, of the elastomeric substance being formed in the mold flows into the bore of the vent plug.

A method and apparatus for separating cells according to differences in sedimentation velocity comprises a vessel preferably constructed from a cylindrical body of ring formation, the height of which is substantially less than its diameter, and from top and bottom plates sealingly and removably attached to the ring. The vessel is preferably mounted on a tiltable platform for controlled movement be...
