Abstract: A paper dispenser is furnished with one or more turnable or tiltable cutting or tearing off device, equipped with serrated or jagged edges. When inactive, the cutting edge is held by a spring or by force of gravity in a safe or innocuous position. As a drawing force is applied to the paper web coming out of the dispenser, the cutting or tearing off device is turned or tilted so that the serrations of the cutting edge come into contact with the paper web. When a portion of the web is torn off, the jagged edge returns to its shielded position. The cutting or tearing off device can be directly actuated by the paper web, or via an intermediate element.

Title: Ac power control
Inventor: PELONIS KOSTA
IPC: G05F1/455
Filed: 1986-07-08
Granted: 1991-09-10
Abstract: ABSTRACT             A device for regulating delivery of power from an AC voltage source to a load such as a lamp, a motor, a heating element or the like is described. Electronic circuitry responsive to the AC voltage generates a periodic signal whose magnitude indicates the instantaneous phase angle of the AC voltage relative to the most recent zero crossover of the AC voltage throughout the entirety of each half cycle of operation. A comparator generates a triggering signal when the phase angle signal corresponds to a threshold signal which may be manually set by adjustment of a voltage divider or which may be generated by a sensor in response to a predetermined condition, such as ambient light level or temperature, which is to be regulated by appropriate delivery of power to the load. The triggering signal is applied to a triac series connected with the load to initiate conduction of load current. The device permits the phase angle at which current conduction is initiated in each half cycle of operation to be controlled over substantially the full range of zero to 180 degrees.

Title: Image orientation and animation using quaternions
Inventor: WITEK F ANDREW
IPC: G06T13/00
Filed: 1987-11-13
Granted: 1992-12-08
Abstract: Abstract of the Disclosure A method for orientating and animating video images using quaternions to provide smooth, predictable rotations in a digital video effect device.  Euler angles for a new orientation are input by an operator and are converted into an appropriate quaternion.  For incremental orientation changes the appropriate quaternion is combined with the current quaternion of the video image in either source or target space to form a new quaternion for the new orientation of the video image. A selected plurality of such new quaternions in a sequence make up the video effect keyframes.  in executing the video effect a Bezier spherical linear algorithm is used to interpolate intermediate quaternions on a video field by field basis between neighboring pairs of keyframe quaternions based upon the source keyframe quaternion, the destination keyframe quaternion, a source outgoing keyframe quaternion, a destination incoming keyframe quaternion and an inbetweening time coefficient.  The intermediate quaternions are fine tuned by referring to tension, continuity and bias parameters.

Title: Apparatus and method for temporarily sealing holes in  printed circuit boards
Inventor: CHOINSKI EDWARD J
IPC: H05K3/00
Filed: 1987-11-25
Granted: 1991-02-19
Abstract: ABSTRACT OF THE DISCLOSURE An apparatus and method for temporarily sealing holes in printed circuit boards are disclosed.  The apparatus comprises two major assemblies:  a heater block assembly and a vacuum table assembly.  The heater block assembly employs a temperature controlled, insulated heater block having a surrounding, movable vacuum collar.  A flexible, thermally conductive vacuum skin is mounted on the movable vacuum collar and forms a vacuum chamber in cooperation with a movable vacuum table having a flat, porous plate whose upper surface is parallel to the vacuum table surface.  A sandwich comprising a porous release sheet, the printed circuit board, a thermodeformable material and a thermally conductive cover sheet is positioned on the vacuum table flat, porous plate.  Thereafter, the vacuum table and sandwich are moved together so that the table forms a sealing relation with the flexible, thermally conductive vacuum skin.  A vacuum is then drawn in the now formed vacuum chamber forcing the flexible, thermally conductive vacuum skin against the sandwich to compress the porous release sheet between the printed circuit board and the flat, porous plate.  At this point, the flexible, thermally conductive vacuum skin, sandwich and vacuum table are moved into a position in which the flexible, thermally conductive vacuum skin is forced into thermally conductive contact with the heater block.  Heat from the heater block softens the thermodeformable material so that it deforms into the holes of the printed circuit board forming protectively sealing plugs therein. After cooling, the vacuum table is moved in the reverse direction to permit removal of the sandwich.

Title: Instrument control system and method
Inventor: SOKOLOW STEPHEN A
IPC: G05B19/042
Filed: 1987-12-02
Granted: 1991-05-14
Abstract: ABSTRACT          Method and apparatus for controlling an instrument which can perform a specified cyclic process.   The instru-ment's process is controlled by a computer which has two concurrently defined tasks: an operator task for running an instrument control program, and a compiler task for compiling new instrument control programs input by the instruments user.   The currently running program is suspended and a new program's execution is begun when (a) a new program has been successfully compiled by the compiler,  and  (b)  the  current  program  is  about  to perform a jump back at the end of an instruction loop. When a main instrument control program finishes execut-ing, a new program is run if a new program has been successfully compiled; otherwise, execution of the most recently suspended  program  resumes.   Thus  a  newly compiled  program  interrupts  the  currently  running program only between instruction loops, and only as long as necessary to execute its instructions.  If the newly compiled program merely resets a parameter, this inter-ruption is generally so short as to be unnoticeable. If, on the other hand, the newly compiled program is designed  to  control  the  instrument's  process  for  a period of time, the new program takes control until it finishes  execution.   Thus  the  instrument's user  is provided not only with the feel of being able to reset parameter values on the fly, but also with a flexible tool for revising an instrument control program on the fly.
