Abstract: A hose clamp machine includes a frame carrying a reciprocating air motor, the piston shaft of which is coupled to one end of a lever which is pivoted approximately midway between the ends thereof on the frame, the other end of the lever being coupled by linkage to a band puller housing for slidably reciprocating it along a slide rod. A hose with a hose clamp band looped thereabout is mounted beneath the distal end of the slide rod with the free end of the band fed through a ratchet-type holding dog to a pulling dog in the puller housing. Pivotal movement of the lever during a driving stroke of the motor pulls the puller housing to tension the band, after which a punch head is driven into the band collar to lock the clamp in the tensioned condition about the hose. Cushioning means is provided on the piston shaft to cushion the driving stroke when the band is severed while under tension.

Abstract: Disclosed herein is a portable frictional welding device whereby union of a metallic part with a given structure is accomplished by fastening said metallic part to the rotary shaft of the device supported slidably in the axial direction thereof, operating the rotary shaft so as to rotate the metallic part and at the same time pressing it against the structure and, when the point therebetween has assumed a state of fusion, stopping the rotation of the rotary shaft and simultaneously increasing the thrust being applied to said structure.

Abstract: In an automatic gas pressure welding system wherein a couple of steel members are butted, the butted section is subjected to heating in a pressed state, to thus cause the steel members to be subjected to pressure welding. The pressing and heating periods are controlled in conformity with the amount of contraction of the heated section of the steel members.

Abstract: A guard member is mounted on the chain saw for swinging movement between an actuate position and a reset position. The guard member occupies a normal position between the actuate and reset positions. A brake band is integral with a bowed column spring which applies the braking force to arrest movement of the cutting chain. A latching mechanism includes an arm with a latch pin engaged by a yieldable latch finger; this latch finger is integral with the bowed column spring. The guard member deflects the latch finger in response to movement of the guard to its actuate position; this action allows the column spring to apply the brake. The guard member is moved to its actuate position in response to a sudden movement of the chain saw, as in the case of "kickback"; this movement of the guard member is brought about by inertia or the engagement of the guard with the operator's body (most likely the wrist or the back of his hand) during this abrupt movement of the chain saw.

Abstract: Small articles, such as miniature ceramics having integrated circuits bonded thereon, are adjacently positioned with an initial row orientation in parallel first rows in guide tracks having a first row spacing. The first articles in each track are lifted from the tracks by a transfer arm, having rotatable vacuum pickups, along a line angular to the tracks such that the articles have a predetermined second row spacing measured along the transfer arm. The lifted articles are transferred to second rows of vacuum supports therefor by pivoting movement of the arm. The supports have pedestals in columns transverse to the second rows which are indexed into position for repeated transfer of articles thereto to form an array (or matrix) of articles having the second spacing between the second rows of the articles on the supports. A link mechanism is provided to rotate the vacuum pickups and re-establish the initial row orientation of the articles with respect to the second rows.

Abstract: This invention relates to methods for soldering metals to superhard man-made materials such as diamond, boron nitride and hexanite and to soldering agents therefore. A method is proposed which comprises applying a metallizing coating to the soldering surface of the materials based on diamond and/or boron nitride, the materials to be joined by soldering being exposed to a temperature sufficient to bring about adequate adhesion of the metallizing coating to the materials to be soldered, and subsequently soldering the metal with the material bearing the metallized coating by use of soldering agents featuring ductile properties and melting points in the range up to 1,000.degree. C, whereby, in accordance with the invention, the metallizing coating is constituted by metals showing high adhesive activity toward materials based on diamond and boron nitride and accounting for from 3.0 to 65 percent by weight of the coating and by metals showing poor oxidizability which account for the balance.

Abstract: An insulation stripper is described which is especially useful for shielded wire, the stripper including a first pair of jaws with blades extending substantially perpendicular to the axis of the wire, and a second pair of jaws with blades extending substantially parallel to the axis of the wire. The first pair of jaws is pressed against the wire so the blades thereof cut into the insulation, and the device is turned to form circumferential cuts in the insulation. Then the second pair of jaws is pressed against the wire so the blades thereof cut into the insulation, and the wire is moved through the device to form longitudinal cuts that permit easy removal of the insulation. Each of the blades is located within the concave face of a V-block, to center the blades on the wire and to limit the depth of blade penetration.

Abstract: A cartridge containing an explosive charge is placed within a tube assembled within a tube sheet. The charge is detonated through use of a detonator cord containing a minimum but effective amount of explosive material. The cord is contained inside a tubular shield throughout most of its length within the cartridge. A small length of the cord extends beyond the tubular shield to contact and detonate the explosive charge in its rear portion near the cartridge base. The cartridge base is provided of substantial mass and thickness in respect to side and front walls of the cartridge to minimize bulging beyond the rear face of the tube sheet. For remote activation an electrically activated detonator of higher charge density than the cord is attached to the cord at a location spaced from the tube sheet, cartridge and tube.
