Abstract: Abstract of the Disclosure An apparatus for freezing confection material includes a plurality of separate mold strips which are indexed in a closely spaced single file over several longitudinally spaced, transversely extending rows of nozzles.  Coolant is forced upwardly from the nozzles in single vertical jets which impinge perpendicularly against the mold strips midway between adjacent mold cups.  The mold cups are arranged with their wide side faces extending in their direction of travel, and the single jets of coolant impinge upon wall portions of the mold strips which extend transversely between such opposing wide side faces.          The heat exchanger for refrigerating the coolant includes a vertically super-imposed array of heat exchanger tubes that is located directly under the mold cups so that the coolant will drip from the mold cups onto the heat exchanger tubes.  The coolant then cascades from upper to lower heat exchanger tubes and is refrigerated by the time it trickles into a collection housing situated below the heat exchanger.          Mechanical seals are formed between the adjacent mold strips by intermeshing end walls of the mold strips; the seals enable the coblant to be continuously sprayed without concern that the coolant may be injected upwardly between the strips to contaminate the confection material.

Abstract: ABSTRACT OF THE DISCLOSURE:           Method of making a great number of weld beads in the form of independent contours spaced apart by means of an auto-matic welding head comprising a torch and means for displacing the torch in several directions allowing the latter to follow each contour one after the other.  The method is characterized by the fact that after striking of the arc and positioning of the torch on the first contour to be welded and then making of the first weld bead have been effected in a known way, the torch current is decreased to effect a partial fading out of the arc.  A displacement of the torch is then effected as far as a starting position on a second contour to be welded, and a timed stationary preheat is effected at this point by control-ling the return to welding current.  The second weld bead is made by following the second contour to be welded, the torch current is then decreased to obtain a further partial fading out of the arc, and a further displacement of the torch is effected as far as a starting point on a third contour to be welded.  The third contour is then done and so on, transfer from one contour to the other and adjustment of welding para-meters is effected automatically until the last bead is made.       The arc is then switched off.

Abstract: Abstract Cleaning Method and Apparatus for an Electrographic System A method and apparatus are disclosed for varying the pre-clean corona current in an electrographic imaging system of the type employing a toner-coated carrier in the development process.  The pre-clean corona current is adjusted periodically during the lifetime of the carrier as necessary substantially to neutralize the charge on residual toner so that it may readily be removed by a rotating cleaning brush having substantially no charge thereon. Adjustment is in response to a periodically sensed aging characteristic, such as successive preselected operating time intervals representing increments of carrier useful lifetime, or charge density of the toner which decreases as the carrier ages.  In this manner, cleaning efficiency is maintained.

Abstract: brake spring 53 and disengages the brake shoe 42 from the brake band 43.  After the brake shoe and brake band are dis-engaged, frictional contact between the contact surface 31 and 41 causes the housing 36 to be rotated substantially at the speed of rotation of the drive shaft 14.  If the cutter blade or other rotating element 46 strikes a solid object such as a rock or the like, relative sliding movement may oc-cur between the contact surfaces 31 and 41 to reduce or pre-vent damage to either the rotating element or the drive con-nection.  Also, if the cutter blades of a lawnmower should encounter a clump or thick or tall grass which normally would stall an internal combustion power plant, the power plant of the present invention will slow down and immediately the re-turn spring 33 will retract the weights 25 and disengage the contact surfaces 31 and 41.  When this occurs, the brake spring 53 urges the housing upwardly so that the brake shoe 42 engages the brake band and interrupts rotation of the housing.  Since the power plant is thus relieved of its load, it is free to retain its operating speed at which time it will again operate the cutter blade.         When the speed of rotation of the power plant 11 is intentionally reduced, such as for emptying a grass cat-cher bag or the like, rotation of the cutter blade is inter-rupted so that such cutter blade does not present a hazard to the operator if he should inadvertently insert his hand or foot under the deck 12.

Abstract: WOUND CLOSURE TAPE AND APPLICATOR THEREFOR                    ABSTRACT OF THE DISCLOSURE          A wound closure tape applicator has an elongated trapeziform casing partitioned into a front supply chamber for a roll of adhesive tape carried on a backing strip or liner and a trapeziform rear storage chamber for collecting waste backing strip.  Front and bottom walls of the casing form a tape outlet slot in a lower front corner of the supply chamber.  A cylindrical post extending horizontally between the casing sidewalls internally adjacent the slot guides the tape downwardly along the front wall.  A front end portion of the bottom wall projects upwardly close to the underside of the post and guides the liner rearwardly to peel it away from the tape as the latter is pulled downwardly through the opening. A false bottom wall in the casing guides the liner rearwardly along the bottom wall beneath the partition into the rear chamber. The front wall includes a brake flap which is resiliently deflectable to press the tape against the post to separate an applied segment of the tape from the roll along the perforations and to control tension in the tape being applied.     The tape but not the liner is perforated and notched at regular intervals along its length.  The tape is preset or "aged" in roll form so that when the waste liner is fed into the storage chamber it will coil without regard to the shape of the chamber.
