The swinging pillow has a shape which can maintain the proper position of a user's backbone and can facilitate the user's turning over onto his side. The pillow can have a built-in sound source in its interior so that the pillow can be used also for relaxation or for the purpose of treatment sleeping disorders, such as sleeplessness, and has a function equal to or near that of an earphone or headphone, without employing such devices. The swinging pillow comprises a pillow body for accepting a us...

A swinging saw has a saw blade performing a working movement with a superimposed swinging movement, a displacement rod supporting the saw blade and performing a swinging movement, a displacement rod support having an opening opening through which the displacement rod is guided. The displacement rod is guided such that relative movement, or play, is provided between the guide and the displacement rod in the swinging plane while play is prevented in a plane transverse to the swinging plane.

Load-bearing swinging arm which causes an advance movement of a mobile device by means of its pivoting movement is pivotally connected to a supporting structure in a pivotal relationship thereto about an axis of rotation, and a pair of actuators for effecting the pivoting movement is provided between the swinging arm and the supporting structure. The points of action acting on the supporting structure by way of the actuators are provided on both sides of the axis of rotation. The points of actio...

A swinging toy comprises a U-shaped frame having two spaced parallel support rods and a connecting fulcrum rod. A figure comprises a body member simulating a head and shoulders with two arm members rotationally connected to the body member at the simulated shoulders. An outer string line is connected between the parallel support rods near one end of the frame and passes through inner openings of the arm members. An inner string line is connected between the parallel support rods parallel to and ...

Disclosed is a centrifugal cytology swinging bucket for providing multiple dispersions of fixed cells or other particles onto a microscope slide or similar substrate, the bucket comprising a slide holder for receiving a slide and a transparent sample block having a sample chamber with drill holes for fluid communication between fixative cups, such fixative cups having porous frits therein. The bucket further comprises a pair of holddowns each having an eccentric cam and a lever protruding theref...

A swinging device for controlling opening and closing of a shut-off valve or the like includes an oscillating crank which is pivoted with its one end to a nut reciprocating on a spindle driven by an electromotor via a gear transmission. The oscillating crank swings between two end positions and is provided with an elongated slot in which a prolongation of a coupling member projects in shiftable but non-rotational manner. In both end positions of the crank which correspond to the respective openi...

A swinging drawbar and drawbar carriage supported on a bail assembly forming lateral abutments engaging the drawbar and carriage to overcome twisting and distorting moments on the drawbar when lateral movement of the drawbar is arrested at its extreme lateral positions.

An apparatus for converting rectilinear motion to rotational motion about a first axis having two pivotal members fixed about and rotatable with respect to each other and to the first axis, two hydraulic motors interconnected between said pivotal members, a source of fluid power supply connected to each hydraulic motor by conduit means, directional flow control means for selectively delivering fluid power to the hydraulic motors, sequence valve means for sensing the position of the hydraulic mot...

A swinging door comprising a vane supported about an axis, wherein the vane comprises a first portion of predetermined width and a second portion of greater predetermined width. The first portion is attached to the second portion so as to make a predetermined angle therewith of between 90.degree. and 175.degree. and the axis is adjoined within the first portion or is in the region of the plane of the second portion.
