Abstract: A process for coiling warp beams of looms involves winding new warp threads on warp beams with free ends of predetermined length double wound on the beams at the beginning of the winding process. A warp beam with a securing system for warp threads arranged to leave free ends of the warp threads is described. For changing a warp beam, the free ends of the double coiled warp threads are released from the warp beam before the beam is completely unwound and the free ends are tied to the leading ends of warp threads on the next succeeding warp beam without stopping the weaving process.

Abstract: An improved manufacturing technique for producing a certain class of Surf Acoustic Wave (SAW) devices, namely those having input and output transducers in close proximity. A much higher manufacturing yield results from eliminating the cutting of a slot in the substrate between input and output transducers as formerly done. This frequently destructive step is replaced by ion-milling of a deep groove between the ports and backfilling with a metal of proper configuration to provide elecromagnetic shielding. The technique produces a new device that is at least equal to the prior art in rejection of unwanted couplings between input and output.

Abstract: Different size holders and a press for installing constant velocity axle seals and metal retainer rings. The holders have internal walls which are angled 11/2 degrees to allow the axle, joint seal and metal retainer ring to be seated firmly and perpendicular on the holders internal shoulder, the holders can be moved in the press base to position it on the center line of the axle compression screw. The press base has an opening just large enough to allow the holders to be located under the screw if needed. The axle is then pressed into the joint seal and metal retainer ring. The press is portable and can be mounted on a horizontal surface. The axle can be pressed into the joint seal and metal retainer ring manually or by a powered air or hydraulic cylinder. Pressing the constant velocity axle into the joint seal and metal retainer ring eliminates clamping the constant velocity axle in a vise and hammering the seal and ring onto the axle.
