Abstract: ABSTRACT OF THE DISCLOSURE          This application depicts a rectangular color cathode ray tube having a faceplate and a mating funnel, on the face-plate of which is a system of four suspension devices, one at each corner of the faceplate, for detachably supporting a non-self-rigid shadow mask adjacent a screen-bearing inner surface of the faceplate.  At least three of the mask suspension devices each comprise mask-mounted and envelope-associated components, the device being characterized by one of the components including an axially extending, non-folded leaf spring which is cantilevered such that it deflects with an arc of motion in a plane perpen-dicular to the mask and preferably passing through the mask axis, and which has at its distal end provision for detachably engaging a mating provision on the other of the components.  The leaf spring is arranged such that the force exerted by it on the mask is preferably through the mask along a diagonal thereof so as to preclude the imposition of any substantial moment on the mask.  The leaf spring has a relatively low spring rate, (stiffness), i.e., in the flexure out of its plane, yet is very stiff in its own plane such that the three devices acting in concert precisely fix and hold the mask in a predetermined spatial position relative to the faceplate against translational or rotational displacement, in spite of any thermal expansion or contraction of the mask, demounting and remounting of the mask, or mechanical shocks and do so without deforming the mask.

Abstract: CONVERSION OF STRIPE-GEOMETRY JUNCTION LASER EMISSION TO A SPHERICAL WAVEFRONT            Abstract of the Disclosure In a micrographics system of the type in which holes are machined in a thin film by means of a laser (see, for example, reissue patent No. 28,375 of D. Maydan, M.I. Cohen and R.E. Kerwin, granted March 25, 1975), it is advantageous that the laser be a solid-state unit of the stripe-geometry double-heterostructure type.  But the optical output beam of such a laser typically exhibits astigmatism and an elliptical cross-section.  To assure high-quality machining of the film, it is important that the astigmatic nature of the beam be corrected and, in addition, that the beam be converted to one having a circular cross-section.  As described herein, this is ac-complished by means of an inexpensive and easily adjustable compact array of optical components that are relatively insensitive to beam-steering and to certain filamentation effects that may occur in the laser.

Abstract: ABSTRACT OF THE DISCLOSURE      A crimping machine for radially inwardly crimping an end fitting onto a hose by means of a contractible die assembly includes a reciprocable ram.  A pusher assembly is mounted on the ram for transmitting ram force to the die assembly. The pusher assembly includes first and second semicircular pusher memebers, and the pusher members are mounted for axial movement with the ram and for lateral movement relative to the ram.  The die assembly includes two disjuncted die sections, one of which is carried on the end of each pusher member by connecting means which permits relative radial movement between the die section and the pusher member.  A cam follower on each pusher member follows a cam surface on the machine for moving the pushers laterally outwardly when the die sections are pulled from the socket by the pushers during retraction of the ram.  During advancing movement of the ram, the cam surfaces close the pusher halves and the die sections carried on the pusher halves to form a die cavity in which the workpiece is located.  Further advancing movement of the ram after the pushers and die sections come together forces the die sections into a conical socket to radially inwardly deform the workpiece.
