    Abstract: A method is provided for manufacturing a heat shield for an exhaust system component. The exhaust system component preferably is of tubular nonlinear configuration. The heat shield is formed from a larger pipe having an internal diameter greater than the outer diameter of the exhaust system component. Appropriately dimensioned inwardly directed supports are formed in the larger pipe. The larger pipe then is bent into a nonlinear configuration substantially identical to the configuration of the exhaust system component. The outer pipe then is cut longitudinally in half along its entire length to define a unitary nonlinear heat shield which can be mounted to the exhaust system component. A portion of the remaining half of the larger pipe can be reattached to the heat shield to provide an air gap pipe along a portion of the length of the exhaust system component.

    Abstract: A strip of fasteners such as pierce nuts is formed from a metal blank with no scrap resulting from the provision of a spacing between adjacent nut bodies, and without the difficulty and expense incident to attaching nut bodies to connecting elements. The body portion of a laterally flanged blank is severed in the transverse direction to separate nut bodies from the blank without fracturing the flanges. The flanges are severed in the longitudinal direction to form severed longitudinally extending flange segments integral at both ends with unsevered flange segments. When the flanges are straightened, the stretching of the severed flange segments resulting from shearing provides a spacing between adjacent nut bodies in the strip. The strip includes spaced apart nut bodies interconnected by continuous lateral flanges.

Registration holes are punched about the planar element, so that these may be readily stacked relative to each other, as required to form the surface to be constructed. Sprocket holes are also punched in the sheet material to advance the material along a processing path at which the various processing stations are located.

The head is particularly useful for extruding sidewall strips in the manufacture of pneumatic tires. The head design has features common to both conventional strip extruding heads and to heads for extruding tubular shapes, commonly called tuber heads. However, the head is quite different from both the conventional strip extrusion heads and the conventional tuber heads, and has the advantage that it permits two strips to be extruded simultaneously through passages that are relatively short in length and are no wider than the width of a single sidewall strip. The design of the head and the method of making it are such that the extrusion passage surfaces can be easily machined to provide excellent flow characteristics, and the entire head is easily fabricated and cleaned.

  • Patent number: 4264998
    Abstract: In a wiper assembly (10) for a windshield, a window, a headlight, or the like, including a flexor (20) for a resilient wiping element (21) having laterally extending tabs (45,46) and lateral indents (55,56) defined on the flexor by the lateral edges (33,34) thereof. A plurality of such flexors are cut from a sheet of material without substantial waste by orienting the flexors to be cut in abutting side-by-side relationship such that the tabs of one flexor are cut from laterally aligned indents of an adjacent flexor on the sheet. The pair of tabs (45,46) have axially spaced external shoulders (49,52) located near one end (30) of the flexor with one shoulder on each lateral side of the flexor and the pair of indents (55,56) have axially spaced internal shoulders (59,62) located near the other end (31) one on each lateral side of the flexor such that adjacent flexors are oriented 180.degree. relative to each other when they are to be cut apart from the sheet.

  • Patent number: 4216523
    Abstract: A printed circuit board substrate is subdivided into sections, the boundary of each section being defined by notches which weaken the substrate and thereby permit the substrate to be fractured at the boundaries of the sections to permit the removal of a defective section. Printed conductors which electrically connect one section to another pass over the weakened substrate regions and when a section is removed, these conductors fracture at the boundary of the removed section. A replacement section may then be substituted for the removed defective section and its conductors connected to corresponding fractured conductors on the substrate.

  • Patent number: 4194280
    Abstract: Machines and process for making in a continuous operation a prestressed glass reinforced, thermally insulating panel, structurally stiff, and totally impervious, of indefinite length and with a cross-section shaped as an elongated parallelogram.Steps for manufacture include making the surface of the panel out of a tubular envelope of knitted or woven glass fabric, stretched over a special holding frame, to give it the desired parallelogram shape. Fastened by a continuous knitting process to the opposite faces of the glass fabric envelope, other glass fibers are stretched inside the envelope and arranged according to three principal directions, all of them oblique with respect to the panel faces. The glass fabric envelope is then coated with a plastic resin to make it impervious to gas and covered on one face at least with a metal liner. This liner, made of cryogenic alloy, has its edges upturned and folded, so as to be fastened to the glass reinforced plastic envelope.

  • Patent number: 4184719
    Abstract: A rail for a machine carriage has an elongate base plate and a pair of spaced supporting walls extending along and rising obliquely from the base plate and converging toward each other in a direction away from the base plate. A first lateral carriage track is located on top of and extends along one of the supporting walls, while a second lateral carriage track is located on top of and extends along the other of the supporting walls and in parallel to the first track. An elongate top plate extends between the first and second lateral carriage tracks and is spaced from the base plate. The base plate, pair of supporting walls, first and second tracks and top plate are integral with each other and encompass an elongate hollow space extending through the rail. Apparatus for supporting and guiding a cutting machine, a machine carriage, and a method of making a machine carriage are also disclosed.

  • Patent number: 4139933
    Abstract: A microscopic length scale typically about 50 .mu.m long and graduated in several intervals ranging from 1 .mu.m to 20 .mu.m. The scale is useful in calibrating the magnification of scanning electron microscopes (SEMs) and other electron imaging instruments. The scale comprises alternating layers of two metals deposited on a substrate. The two metals have substantially different electron emission coefficients to provide contrasting emission signals when scanned by an electron beam. One of the metals, preferably gold, is deposited in uniform layers about 40-80 nm thick. The other metal, preferably nickel, is deposited in several layers ranging from 1 .mu.m or so thick near the substrate to 20 .mu.m thick in the outermost layer. The resultant multilayer composite is cut into one or more samples and each sample is mounted on edge. The exposed edge is ground and metallographically polished and a microscopic indentation is made in the substrate near the first gold layer.
