  • Patent number: 6148873
    Abstract: A suitable automatically operating apparatus is proposed for producing reinforcing cages for rectangular pipes made of concrete. Longitudinal-wire sections, which are parallel to the pipe axis, are held together in a framework. The latter essentially comprises a perforated frame, which cannot be moved in the longitudinal direction, and a receiving frame, which can be displaced relative to the perforated frame. Rectilinear transverse-wire sections, angles or bent brackets are welded onto the longitudinal-wire configuration, to be precise onto the respective side surfaces of the longitudinal-bar configuration in a freely selectable manner. Fitting apparatuses which can be displaced perpendicularly with respect to the longitudinal-wire sections are used for this purpose. In addition to the wire thickness, it is also possible to select the spacings between the transverse-wire sections provided in each case.

  • Patent number: 4880217
    Abstract: This invention is an annular or garter spring having a welded overlapping region. In this invention, the end tips of a straight spring fit within the spaces between coils at the opposite end of the spring. This result is reached by first hooking an end tip of the spring through the first whole coil at the opposite end of the spring, then placing the opposing end tip between the first and second full coils of the first side of the spring. The coils at the ends of the spring are then clamped to so that each end tip aligns alongside the first full coil of the opposite end of the spring. When that position is reached, the spring will form a virtually perfect ring, and the intertwined coils may be welded together to maintain the garter spring shape.

  • Patent number: 4840204
    Abstract: An apparatus for bending leads axially protruding from a component includes a pair of spaced apart discs mounted on a shaft. Each disc has a plurality of generally V-shaped cutouts that are axially in registry with the cutouts on the other disc such that the component is retained in a registered pair of cutouts. The span between opposing leading and lagging surfaces defining each cutout, is related to the radius of curvature of a partially conically shaped lagging outboard edge of the cutout by a predetermined function. In other words, due to the V-shape of the cutout, the head is held at a certain radial position in the cutout between the leading and lagging surfaces of the cutout. At this radially coincidental point, the span of the cutout of course equals the diameter of the lead. The radius of curvature of the lagging outboard edge of the cutout at that radially coincidental point is made a predetermined function of the diameter of the lead, for example equal thereto.

  • Patent number: 4495973
    Abstract: An apparatus retapes axially taped electrical components into quasi-radially taped component. The apparatus feeds the axially taped electrical components to a work station one-by-one, at which one pigtail or lead wire of each component is bent around a bending mandrel by means of a bending element protruding beyond a rotatably or swingably mounted carrier, so that, after bending, the component with U-shaped leads is held suspended from the bending mandrel on its bent lead wire. An inserter device transfers the component with the bent lead wire onto a receiver of a transport element by sliding the component held suspended on the bending mandrel onto the receiver of the transport element, which then stepwise transports each bent component away from the work station.

  • Patent number: 4380192
    Abstract: A device for broiling elongate food articles, such as hot dogs, sausages, etc., comprises a rod having a handle at one end, and food retaining baskets connected with the other end of the rod. The baskets are detachably connected with the rod by support wires which extend laterally from both the open and closed ends of the baskets, and have bent over free ends which form eyelets through which the rod is closely received. The rod end opposite the handle is threaded. The support wires at the open ends of the baskets are threaded over the threaded area of the rod, onto a lower portion thereof, to non-fixedly mount the upper ends of the baskets. The support wires at the closed ends of the baskets are disposed on the threaded area of the rod, and a pair of threaded nuts are positioned on opposite sides of the support ends, and are tightened against each other to fixedly, yet detachably, mount the lower ends of the baskets on the rod in a predetermined configuration.

  • Patent number: 4373558
    Abstract: An illustrative embodiment of the invention produces comb-like bookbinding wire stock in a manner that significantly reduces wire breakage during manufacture as well as unequally stressing or stretching or marring the surface finish of the wire from which the stock is formed. An indexing unit drives a pair of forming arm members that pivot under the control of a cam surface. These members align and wind a wire strand onto pins that protrude radially from a pair of parallel, axially spaced rings. Operation of a reciprocating side pusher and center pusher shaft press the wire strand onto the adjacent pins and a wire flattening roller presses one side of the partially formed stock against the adjacent pin surfaces to produce the "back" for the comb-like stock. A rotating pinch roll "sets" the fingertip portions of the tines on the stock.

  • Patent number: 4372351
    Abstract: A frusto-conical shaped wire basket is formed of a plurality of upright wire loops welded in substantially perpendicular relationship to a plurality of wire rings. The baskets are formed by first welding wire connecting members to a plurality of arcuately shaped lengths of wire. Each of the arcuate lengths is of a different length and radius, and they are arranged concentrically in order of decreasing radius. The relative lengths of the arcuate segments are determined by the desired size of the finished basket. When the wire connecting members are welded to the arcuate segments in the first stage of basket production, there is formed a basket flat. The flat is then subjected to a conventional pinch roller mechanism which bends the flat into a conical shape. At that point the ends of each arcuate length are in face-to-face relationship and form a circle. The ends are then butt welded to close each circular ring to complete the wire basket.

  • Patent number: 4343466
    Abstract: An exercising device has a body made from one solid continuous piece of contoured rod using the variable friction resistance rope principle. The body is formed having two spaced rod sections, one end of each of the rod sections bends inwardly and extends towards a center line with the two rod sections then bending to extend substantially parallel to a point where they then bend towards each other and join to form a curved end; this arrangement forms a neck and shoulder portion. The two spaced rod sections taper towards each other where they form short parallel rod sections at the opposite end of the body with the ends of the rods joining to form a second curved end. Resistance is varied by passing the rope around the rod a selected number of turns. The number of loops around the rod directly affect the friction resistance developed.

  • Patent number: 4313474
    Abstract: The present invention relates to a method for the manufacture of a hyperfrequency delay line. The method comprises using a single metal wire shaped by the coiling thereof, said operation comprising bringing the wire into the form of contiguous coils. Coiling is followed by a wire cambering operation during which the coils are deformed at regular intervals in the axis of the line by using wedges, in such a way that the line is formed by a succession of identical groups of three coils in which the first and third coils have identical but oppositely directed inclinations with respect to the axis and in which half of the second coil remains contiguous with the first coil and half remains contiguous with the third coil. Application to the manufacture of double helix delay lines, of ring and bar and ring and loop lines, used in travelling wave tubes functioning as amplifiers.

  • Patent number: 4283119
    Abstract: Fiber-shaped metal-containing spacing elements having a well-defined diameter of less than 100 .mu.m for spacing two plates in an indicia display device, such as a liquid crystal cell, are produced by providing a wire composed of a metal selected from the fourth to sixth adjacent groups of the Periodic Chart of the Atoms, converting the peripheral surface layer of such wire into a brittle metallic compound and breaking-up the so-treated wire into desired size individual spacing elements. By utilizing metal wires, an exact diameter dimension can be attained and by chemical conversion of the wire surface, the produced metal wire loses its ductility and can be easily broken-up into desired size elements. Spacing elements of the invention are useful in all types of indicia display devices particularly in multiplex liquid crystal display devices.
