A copying apparatus includes device for reciprocally driving an original scanning device having a drive source movable in a predetermined direction, a movement converting device for converting the movement of the drive source into a reciprocal movement in which the time required for backward movement is shorter than the time required for forward movement, output device connected to the movement converting device to put out a reciprocal movement for driving the scanning device, and speed control device for controlling the speed of the forward movement of the movable member so as not to exceed a predetermined speed.
摘要:
Input torque, at a comparatively low energy level and preferably delivered constantly, is converted to comparatively high energy output torque pulses by storing the applied torque in a leaf spring which, in its unstressed state, is elastically deformed. Energy is accumulated in the spring by twisting it about its longitudinal axis through rotating a first end thereof. Stored energy is released by periodically allowing the second end of the spring to rotate.

A body (1) serving for accommodating material to be processed is movable in gimbal suspensions (35-40) around two mutually spaced axes (39,40) extending in different directions. The body (1) carries out a rotary and tumbling movement by oppositely rotating two parallel shafts (21,22) of which each is connected with one of the gimbal suspensions. For balancing torque fluctuations, a pair of discs (26,27) is arranged on each shaft (21,22) of which the driving-side disc (26) is rotatable relative to the shaft and is connected with a drive wheel (23) while the driven-side disc (27) is fixedly connected with a shaft. In an annular channel (262,272) between the discs (26,27) energy stores in the form of coil compression springs (53) and balls (52) are alternatingly and successively arranged. These elements bear against respective abutments of both discs projecting into the channel. When the discs (26,27) rotate relative to each other, the springs (53) store forces arising at torque excesses which are then subsequently released.

A mechanical torque converter of kinetic-inertial operation, comprising: an input shaft to which a torque is applied; at least one idly rotating mass; means driven by the inlet shaft and adapted to impress on said mass a special periodic rotary motion, means to which said mass transmits the reactions consequent on its motion; and an output shaft on which said means generate a torque, the intensity of which varies in inverse proportion to the instantaneous angular acceleration of the mass, and to the speed of rotation of said outlet shaft.

A machine tool comprising a rotatable spindle, at least one fly-wheel, at least one first roller carried by the spindle and at least one further roller for driving the fly-wheel, wherein the at least one further roller can be engaged with and disengaged from the at least one first roller, so that the fly-wheel can be optionally rotated with the spindle without any play.

Small increments of low force energy are applied to an hydraulic pump which drives an hydraulic motor which energy is converted to a torsional force in a spring. The potential energy in the form of a torsional force in the spring is suddenly and automatically released upon reaching a predetermined torsional force and used to increase the velocity and kinetic energy of a flywheel. A clutch is used to engage the flywheel to permit the kinetic energy stored in the flywheel to perform useful work.

The invention is in inertial energy storage device wherein a central hub holds a multiplicity of anisotropic filaments, the filaments extending from the hub in fixed relation thereto and in parallel planes perpendicular to an axis of rotation taken through the hub. The majority of the filaments in each of the parallel planes are disposed in fixed, arcuately fanned positions, the radius of curvature of the filaments being dependent on the location of said filaments within the hub. A particular feature of the present invention is that each parallel plane of filaments is disposed at angles to adjacent planes of filaments to reduce aerodynamic drag and increase the dynamic stability of the structure.
摘要:
A rotary actuator particularly suited for use aboard operative spacecraft for deploying pivotally supported structures such as, for example, solar panels and the like. The actuator is characterized by a torsion bar coupled with a pivotally supported crank arm through a gear cluster in a manner such that the torsion bar continuously applies a constant deployment force to said solar panel, when the solar panel is in a retracted configuration; serves to deploy the panel at a controlled, sinusoidal rate of acceleration; and subsequently supports the panel in its deployed configuration with minimal supporting forces being applied to the panel through a maximum moment arm whereby structural rigidity for the deployed panel is achieved.
摘要:
In an energy conserving intermittent motion device, energy is alternately stored and released by twisting and untwisting a torsion rod to intermittently rotate a driven member, e.g., a feed platen. The torsion rod is twisted and untwisted by selectively restraining and releasing opposite ends thereof through pairs of clutch devices. Frictional losses in the system are compensated for by a servo-controlled variable torque motor which is controlled so as to supply just enough torque to compensate for the frictional losses.
