F and 500.degree. F, and(c) relatively removing the sleeve from said position.

Abstract: Closely spaced windings of wire are laid down on a revolving drum and retained in place by an adhesive substrate previously mounted on the drum. The cylinder of wire with an adhesive substrate which is formed is cut and removed from the drum and spread into a flat sheet. The wire side of the sheet is placed in contact with the epoxied surface of an elongated plate. The plate traverses the wire sheet in a strip proximate one terminal edge thereof dividing the sheet into a major portion which will ultimately form the lead wires to the head and a minor portion which is trimmed off in later step. After the epoxy has dried, the adhesive substrate is removed and the newly exposed side of the wire is placed in contact with the epoxied surface of a second elongated plate. The two plates form an elongated sandwich containing the wire embedded in epoxy. The ends of the wire forming the minor portion are trimmed and the end surface of the sandwich is polished to form the finished recording head.

Abstract: An operator's console is used to produce, and control the storage of, bend data including: bend number, linear position, rotational position, bend angle and final bend number. The bend data is inserted either manually via a keyboard or by a reader reading a suitable data source (e.g., an optical reader reading punched cards). After all of the bend data is produced, checked and stored, the operator's console displays the first set of bend data. The operator then manually moves the tube, both linearly and rotationally, until the tube is suitably positioned. Encoders mounted so as to detect the rotational and linear position of the tube create related linear and rotational position displays during manual positioning. When the tube reaches the appropriate linear and rotational positions, linear and rotational brakes are actuated and lock the tube in position. When the tube is appropriately positioned (brakes locked), the encoder (actual tube position) displays correspond to the related memory displays.

Abstract: A can end includes a pushdown gate formed in a panel portion below a narrow, underfolded rim at the opening in the end. The outline of the gate is a frangible discontinuity in the panel portion underneath the rim and the same may be ruptured by pushing the gate downwardly and into the can. A method of drawing and folding the end material permits the frangible discontinuity to be formed before the rim is folded over the discontinuity.

Abstract: The invention relates to a process of making small diameter non-skid metallic studs, for tires, composed of a hard material small rod and of a metallic sheath having an elongated longitudinal axis. The sheath includes a fitting or mounting socket for the small rod, at least one small anchoring collar, and a narrowed intermediate section of smaller diameter than the lower and upper adjacent sections. The process comprises forming a sintered rough shaped sheath of at least 85% of theoretical or maximum density which sheath includes the rod's fitting; introducing the small rod in its fitting, leaving an empty space less than 0.6 mm between the rod and the fitting's base; and bringing the sheath to its final shape through trimming or rolling, in particular, in the narrowed section, while holding tightly the sheath's section surrounding the small rod.

Abstract: The invention provides a method of, and apparatus for, producing a layer of antifriction metal on a metallic surface. The method involves using a die having a recess surrounded by a thin rim; the recess is filled with molten antifriction metal which is allowed to solidify, and thereafter the structure obtained is machined to remove unwanted parts of the die.

Abstract: A miniature electrical connector comprising an insulative body having spaced, parallel connector pins extending therethrough and held in place by a combination of abutment surfaces on the pins and block, and "C" rings on the pins. In assembling the connector, the "C" rings are formed as part of a metal stamping, and are urged as a unit onto corresponding ones of the pins extending through the body. The "C" rings are released from the stamping by bending the latter along suitably formed fracture lines.

Abstract: A gripping arrangement for longitudinally advancing elongated workpieces, particularly for use in a drawing bench, a stripping machine and the like, comprises a pair of supports which are mounted on guide rails for movement in paths which are parallel to one another and to the direction of advancement of the workpiece, and co-extensive. Jaw elements are mounted on the supports for movement therewith and for displacement between closed positions in which they engage, and open positions in which they are disengaged from, the workpiece. The gripping arrangement is located downstream of a die and operates in such a manner that always at least one pair of the jaw elements associated with one of the supports engages the workpiece and advances the same in a given direction, thus drawing the workpiece through the die.

Abstract: A method and apparatus for fully automatic fabrication of wiring harnesses is disclosed which is particularly suitable for twisted pairs of telephone wires. Such harnesses are fabricated using slotted-beam connector blocks for all terminations of the harness. Mass-termination to the slotted-beam connectors is accomplished with a pair-indexing head, a comb, and a presser head selectively terminating individual pairs of a bundle of pairs.An automatic connector block insertion station, harness lashing station, and a pair-cutting station, distributed along a moving connector block holding belt, permit continuous automatic harness production.

Abstract: The two bars that form the tubing gripper have tapered sides which mate with corresponding tapered faces on the two legs of the yoke. The direction of the tapering is such that as the flaring cone is forced against the end of a tube in the gripper, the tapered sides of the yoke legs cam the two bars of the gripper together to securely hold the tube in the gripper. A threaded bolt having a wing nut thereon is employed to initially press the bars of the gripper together with a sufficient force to hold the tube in the gripper while the yoke is put in place and the flaring cone initially pressed against the end of the tube.

Abstract: A method for mounting a closed torous tire on a rim by withdrawing a volume of air from the tire, thereafter positioning the tire on the rim, and passing a volume of fluid into the tire.

Abstract: An apparatus has a die with a U-shaped slit for wire passage. The die is connected to an acoustic concentrator of ultrasonic oscillations. The central portion of the slit is parallel to the end face of the concentrator. The wall of the slit central portion that is nearer the concentrator is arranged to be within the zone of the antinode of a standing ultrasonic wave; the area of the wall is not greater than that of the concentrator end face. The length of each lateral portion of the slit is greater than the distance therebetween.

Abstract: A punch for working material, such as an extrusion punch, wherein a hard wear resistant material is joined on one end to a rigid body, preferably a steel punch. The hard wear resistant material is joined on at the tip of the rigid body so as to prevent wear due to abrasion on the punch caused by the material being worked. The hard wear resistant end cap on the tip of the steel body is joined so that it may easily and quickly be replaced when the punch is in position on the machine thereby providing less down time for maintenance on the extrusion press. The method of joining the hard wear resistant end cap to the steel body minimizes the conditions which tend to fracture hard wear resistant material.

Abstract: A system for forming and mounting end closures for peel-top containers, each closure including a peelable sealing membrane, with a folded pull tab, and a separate plastic overcap. The individual sealing membranes are cut from a continuous web and deposited directly on the open ends of cans or containers being fed in a continuing line. Each membrane is retained in properly oriented association with the corresponding container, by adhesive tacking or through a partial vacuum generated within the container, until such time as the container supported membrane is engaged by a chuck to effect a positive sealing of the membrane to the container. After a sealing of the membrane to the container, the container proceeds through a cycle wherein the tab on the membrane is laterally bent, the overcap is applied, and the container with completed end closure is discharged.
