The invention relates to a mammographic apparatus (1) making it possible to produce negatives of breasts of medium to large size and/or medium to high density with the aid of a receiver (86) of the intensifying screen/film pair type, without increasing the dose absorbed by the patient or degrading the quality of the negatives compared to the negatives produced for such breasts with the aid of X- r...

A means and method for applying a stabilizer ply to a tire building drum and more particularly a means and method for cutting and applying the stabilizer ply material and specifically means for cutting the stabilizer ply material between cords disposed therein and correcting for variations of the cord angles during the application process in order to provide an improved splice between the leading ...

A safety ski binding, for retaining the end of a boot to a ski until a threshold bias force is exerted, includes a body for connection to the ski, and a jaw mounted on the front of the body for movement between a closed position at which the jaw is adapted to engage and retain the end of the boot to the ski, and an opened position at which the jaw is adapted to either free the end of the boot or t...

An adhesive composition and a method for its use in bonding rigid PVC elements. The adhesive composition comprises: (1) a first dissolved PVC polymer having a K-value of about 58 +/- and a second dissolved PVC polymer having a K-value of about 45 to about 52; (2) at least one cyclic organic solvent; and (3) at least one non-cyclic organic solvent.

A plural substrate CVD apparatus for diamond crystal production utilizes spaced apart vertical, parallel, planar substrate panels with an electrical (direct current, D.C.) resistance filament heater therebetween. A hydrogen-hydrocarbon gas mixture flows between panels to come into contact with the heater and the panels to cause diamond crystal nucleation and growth on the substrate panels. The app...
