Abstract: SABRE SAW WITH ROTATABLE SAW BAR                            ABSTRACT      A sabre saw is provided with a generally tubular saw bar journalled for linear movement in a journal bushing secured in the top portion of the housing and rotatable therein with means provided so that they rotate together.  The journal bushing is provided with a generally annular collar in turn provided with a plurality of generally radial notches and a cantilever leaf spring is mounted to the housing with its distal end adjacent the collar and shaped for selective engage-ment within the notches.  A slide trigger is slidably carried by the housing at a top portion thereof convenient to the operator's thumb control which when slid towards the saw bar depresses the cantilevered leaf spring against the collar and into a selective one of the notches when they are aligned for locking the saw bar against rotation.  Rearward movement of the trigger slide is effective to release the cantilevered leaf spring wherein it will pop up out of the notch and permit free rotation of the saw bar.  Spring biased latching means are also provided for selectively latch-ing the trigger slide in its forward position.

Abstract: ABSTRACT: "Printing head for ink jet printers".          The printing head of an ink jet printer comprises several tubular nozzle ducts (1) which have the same cross-section and on each of which there is arranged a cylindrical drive member (2). Each nozzle duct (1) is constructed to be integral with its ejection nozzle (3) and the damping member (4) at its rear, and opens perpendicularly into the distribution duct (17) via which the is is applied to all nozzle ducts.         At the area between the drive members (2) and the nozzles (3), the nozzle ducts (1) are bent, such that they extend parallel to one another in the other zones, the distances at the area of the nozzles being determined by the distance required between the ink droplets which are mosaic-wise deposited on the record carrier and at the rear area by the dimensions of the drive members.
