The wheels are mounted on a wheel swiveling mechanism which has a support surface for the bottom end of the uprights. The wheel swiveling mechanism is rotatable relative to the uprights for controllability of the device. Each support surface for an upright is provided on a rocker mounted on the wheel swiveling mechanism for rotation about a substantially horizontal axis.

Abstract: A scissor jack has a leg having a lower end adapted to bear on the ground, a support arm having a lower end pivoted on an opposite upper end of the leg at an intermediate horizontal axis, and a load-bearing member engageable with the vehicle body and formed on an opposite upper end of the intermediate support arm. Upper and lower links are pivoted together at another intermediate horizontal axis with the upper link also pivotal on the support arm between the ends thereof at an upper horizontal link axis and the lower link also pivotal on the leg between the ends thereof at a lower horizontal link axis. A jack screw is connected between the intermediate axes and can draw the intermediate link axes toward one another to raise the load-bearing member or separate the intermediate link axes to lower the load-bearing member. A foot piece can rock on the lower end of the leg relative to the ground about a lower horizontal foot axis as the leg is raised and lowered.

Abstract: In a fiber-gripping device has a gripper head provided with a V-groove for housing an optical fiber and an elastically deformable holding member which is brought to bear on the optical fiber. The gripper head and holding member are provided with V-section channels located respectively in oppositely-facing relation. A cylindrical rod forming a pivot-pin is placed between said oppositely-facing channels. The device is caused to open by a spring which tends to produce a movement of pivotal displacement of the holding member away from the gripper head. A locking lever is adapted to move into a first position in which the holding member is located at a sufficient distance from the gripper head to permit free passage of the optical fiber and a second position in which the holding member fixes the optical fiber within its V-groove and exerts a force which is controlled by its own elastic deformation.

Abstract: This invention is concerned with a cutting surface formed of at least two boards. Each board is rectangular in shape and has opposing, substantially straight edges. There is a notch in one side edge and a projection in the other side edge to permit frictional interlocking and removal of the boards from engagement with one another. A support for guiding the slicing of bread has a base corresponding in shape and size to a projection so that the support can be inserted in an unused recess of one of the boards forming the cutting surface.

Abstract: A device for tightening joints of a wooden type includes a first force transmitting structure and a second force transmitting structure with an assembly for applying force connected therebetween. The force transmitting structure includes a rigid member having a front end portion, a rear end portion and an elongated penetrating portion extending away from the rear end portion.
