Patent EP-0077944-A3 (EP)
Title: Apparatus for paying off wire from a bobbin
IPC: D07B7/06
Filed: 1982-10-07
Abstract: Wire payoff devices are described which are used in conjunction with bobbin supporting cradles typically found in wire stranding and cabling machines such as high speed tubular stranders, bow or skip stranders and planetary stranders. The payoff devices include dancer arrangements each having a pair of pulley wires mounted on a common support member which is itself mounted for independent movements along two substantially orthogonal directions. One of the pulley wheels is effectively fixed and continuously releases the wire along the axis of the cradle. The other or receiving pulley repeatedly traverses the axial width of the bobbin to follow the take-off points of the wire to provide uniform take-off and prevent scraping or chafing of the wire. Movements of the receiving pulley towards and away from the bobbin as a function of the tension of the wire is translated, by means of pivoted lever arms, to a variable frictional force applied to the bobbin which substantially maintains the tension in the wire to a pre-established value.

ide resin or a mixture thereof with a polyvinyl chloride resin, 
a foam conditioning resin, e.g. an acrylic resin or a styrene-­
based resin, and a cell uniformnizing agent, e.g. a heat-­
decomposable blowing agent or an inorganic fine powder; 
supplying the resin composition to the cylinder of an 
extruder machine; uniformly impregnating the at leat partly 
molten resin composition in the cylinder with a volatilizable 
blowing agent by pressurization; and shaping the resin 
composition by extruding out of the extruder with simul­
taneous expansion by foaming.

Abstract: The present invention relates to a structure and a control 
of the playback system grinding robot having a dual 
degree-of-freedom of the polar coordinate which is 
characterized by such a contrivance that No. 2 arm is 
attached in a freely turnable condition to a head of freely 
turnable No. 1 arm and an arm for driving said No. 2 arm is 
arranged adjacent to the said No. 1 arm and an abrasive tool 
is arranged to be freely turnable to different direction and to 
be pressed perpendicularly downward by a hydraulic cylin­
der attached to a head of said No. 2 arm and to be closely 
contacted always to a curved surface of the die notwithstand­
ing that the aforesaid arm driving system takes a plane 
movement.  
     Further, the grinding robot according to the present 
invention is so designed that a direction sensor is arranged 
at a head of No. 2 arm and said sensor acts to store 
directional data together with positional data in a memory 
device at the time of "teaching", especially to input turnback 
point data on the tool traveling locus exactly into the 
memory device in accordance with a change of the direction­
al data and also acts on the control device to cause the 
abrasive tool motion to forcedly decelerate when the direc­
tional data changes at the time of playback work and to 
decide a proper speed of the playback work by using the 
directional data jointly with a variation volume of the 
positional data.  
     Furthermore, the grinding robot according to the present 
invention is provided with a random correction flag device 
which makes it possible to indicate a corrective direction of 
the abrasive tool travelling route at the time of playback work 
in order of (plus "+" correction), (zero "0"), (minus "-" 
correction), (zero "0"), instead of the fiducial locus of the 
abrasive tool taught at the time of ″teaching″ and to correct 
the moving volume in such a way as "0" → "α" → "0" for the 
inputted positional data and to travel the abrasive tool zigzag 
and randomly on its route, thereby ensuring a manufacture 
of the finished products entriely free from facial difference.

IPC: G01N23/18
Filed: 1984-12-20
Abstract: A nondestructive examination method and apparatus for 
high resolution detection of cracks, defects or anomalies in 
radioactivity contaminated materials. The method relies 
upon radioactivity being carried by the normal reactor 
environment, or by an added radioactive penetrant fluid, to 
the cracks, defects or anomalies. Detection of this radioactiv­
ity by a narrow well defined beam gives an improved 
measurement of the location and size of the cracks, defects 
or anomalies. The apparatus includes a sensor mounted on a 
remotely controlled framework. The sensor includes shield­
ing to direct a very narrow beam of gamma radiation to a 
scintillation crystal and photomultiplier tube which converts 
the radiation into electrical signals. The signals are counted 
by count rate means and converted to digital form and 
stored. Survey procedures are provided both for detecting 
cracks and for characterizing cracks once discovered. Com­
puter aided imaging techniques are provided to construct 
graphical representations from the recorded data.
