Title: Patient lift device
Inventor: ZAMOTIN RODVINON I
IPC: A61G7/10
Filed: 1977-03-15
Granted: 1980-09-09
Abstract: ABSTRACT OF THE DISCLOSURE     A movable patient lift device that comprises  a lower base assembly, an upstanding post assembly mounted on one end of the base assembly, a cantilever boom assembly, which includes a track, mounted on the upper end of the post assembly and extending longitudinally at the distal end beyond the base assembly, and a movable trolley assembly in movable engagement with and supported by the track.  The trolley assembly contains a rotatable drum onto which a flexible cable is wound.  A patient chair or sling is attached to the other end of the cable and linkage and gearing is pro-vided to enable an operator to rotate the drum thereby raising or lowering the patient, and to longitudinally position the trolley assembly and hence the patient along the track.          A cantilever platform is pivotally mounted to the base assembly and extends Gutwardly therefrom, preferably in the direction opposite that of the boom assembly.  When an operator mounts the platform, the operator counterbalances the moment exerted by a patient who is suspended beyond the base assembly.

Abstract: FORCE ADJUSTMENT IN IMPACT PRINTERS                ABSTRACT OF THE DISCLOSURE     A plurality of self-restoring equally spaced apart print hammers selectively are driven lineally toward a printing position by continuously rotating impellers having equiangularly spaced radial impelling elements.  Each impeller is effective through the agency of a rockable interponent, which is selectively elevated into the path of associated impelling elements upon latch-ing of the armature of an electromagnet, for transmitting impeller force to a corresponding print hammer.  An elastomeric bumper, disposed in the path of the print hammers, dampens printing force on dies, which are conveyed past said hammers for printing, in equally spaced relationship different from the spacing of said hammers.  Each die, when at a printing station, is aligned with a print hammer but spaced therefrom a distance inversely propor-tional to its printing area for producing copy of uniform intensity.

Granted: 1981-06-16
Abstract: METHOD AND APPARATUS FOR FIBERIZING ATTENUABLE MATERIALS                ABSTRACT OF THE DISCLOSURE    Method and apparatus are disclosed for converting a stream of attenuable material into a fiber by employment of a gaseous jet penetrating a gaseous blast, thereby producing a zone of interaction in which the stream is attenuated to form a single long fiber.  It is contemplated to employ a gaseous jet having lower velocity than the blast and at the same time lower temperature than the blast, thereby providing a jet of higher kinetic energy than the blast so that the jet will penetrate the blast.          It is also contemplated that the glass stream may be initially delivered to the jet to be carried thereby into the zone of interaction with the blast, thereby providing for preliminary attenuation in the jet before the stream reaches the blast.

Abstract: ABSTRACT OF THE DISCLOSURE       The present method involves the detection of local variations of the direction of gravity from the vertical with a degree of accuracy not heretofore obtainable.  In accordance with the present method an inertial system is mounted in a mobile vehicle which moves along a survey route from a first control point to a second control point, with the locations and the deflection from the vertical being known at the two control points.  The vehicle is stopped periodically between the two control points.  At selected stopping points (error removal points), accumulated errors in the inertial system are removed.  At additional selected stopping points (survey points), the accumulated inertial system errors are removed and, in addition, the indicated position of the stopping points and vertical deflection are recorded.  To avoid complex intermingling of errors, the inertial platform is not releveled at each of the stopping points.  When the vehicle reaches the second control point, the position indicated by the inertial guidance system is compared with the actual position of the second control point, errors determined, and the position of the various intermediate stopping points are recalculated using the overall error and the time at which each point was surveyed.  Similarly, the separate errors in the deflection of the vertical and position are determined corrected.  The position and deflection from the vertical of each of the intermediate survey points are then determined, which may then be plotted on a map.

In this photosen-sitive material, the dark decay speed is controlled in a range suitable for application to the repeated copying operation and the residual potential left on the exposure area can be reduced to a negligible level. Accordingly, occurrence of fogging is prevented and the toner transfer efficiency is improved.  Further, this photosensitive material has improved mechanical, chemical and electric durabilities, and therefore, the life of the photosensitive material is remarkably prolonged.                             - 1' -
