  • Patent number: 9505137
    Abstract: A tip end part of a main arm member of a Scott Russell mechanism is enabled to be brought close to a base end part of a sub arm member. A Scott Russell mechanism device is formed into a boomerang-like shape such that a main arm member coupled to a sub arm member is curved to detour a coupling position. Thus, when the coupling angle is changed so that a base end part of the main arm member and a base end part of the sub arm member are most separated from each other, a tip end part of the main arm member can be moved close to right beside the base end part of the sub arm member. With the Scott Russell mechanism device, a moving range of the tip end side of the main arm member can be enlarged.

  • Patent number: 8528379
    Abstract: An apparatus and method for applying tension to flexible items, including wire, barbed wire, cable, or rope, are described herein. A stationary clamping member is fixedly attached to a first end of a guide bar, extending outwardly therefrom, while a non-stationary clamping member is movably mounted to and extending outward from the guide bar substantially parallel to the stationary clamping member. The free end of a first flexible item is secured in the stationary clamping member, while the free end of a second flexible item is secured in the non-stationary clamping member. A tensioning assembly, such as a ratchet-like assembly engaging notches in the guide bar, is used to move the non-stationary clamping member away from the stationary clamping member, thereby tensioning one or both flexible items. Once the flexible items have been tensioned, they can be twisted together to form a connection without losing tension.

  • Patent number: 8359895
    Abstract: A lower die or nest apparatus is described to create a hemming environment that locates and holds a metal panel to a frame using suction in a manner that substantially resists said loads on the panel without damage or deformation. The vacuum nest includes a frame made of a rigid material with an outer work surface and an interior region with a sealed elongated channel shaped to the contour of the metal panel. A polymeric rope is inlayed within a groove formed in the interior region to form the sealed elongated channel. A support member may be formed within the channel by inlaying additional polymeric ropes into grooves formed within the channel. A vacuum source is fluidly coupled with the sealed elongated channel to create a downward force by evacuating the volume of the channel.

    Abstract: A panel, formed from a perforated face (102), is respectively concavely and convexly curved by seriatim stretching or contracting its flanges (104a, b; 156a, b). Such stretching and contracting is produced by placing the opposed flanges within jaw halves (110a, b; 166a, b) of a jaw mechanism (110, 166), by seriatim positioning of the paired flanges between their respective jaw halves, and by moving the jaw halves away from or towards one another. Jaw movement towards one another effects a stretching function. Jaw movement towards one another effects a shrinking function. Computerization enables the panel curving to be precisely controlled. The curved panel, as it exits from the panel curving machine (126, 148) is supported on rollers (146) or, more precisely, by a scissor apparatus (176). The scissors apparatus includes roller sets (242, 244, 246) which are positionable, relative to one another, to conform the roller sets to the curvature of the exiting panel.

The robot preferably comprises a six axis bending robot, in which the distal end of the moveable arm can move relative to the fixed gripping tool about three translational axes and three rotational axes. The gripping tools preferably incorporate force sensors which are used to determine overbends needed to get the desired final shape of the archwire. The robot may also include a resistive heating system in which current flows through the wire while the wire is held in a bent condition to heat the wire and thereby retain the bent shape of the wire.

    Abstract: The present invention relates to a method and apparatus (1, 31) for forming a three-dimensional object and in particular to a method and apparatus (1, 31) for forming a three-dimensional beam (5). It is desirable to form three-dimensional beams (5) having complex forms by using an efficient forming process for the beams which may be incorporated into existing high volume production techniques. The apparatus (1, 31) for forming three-dimensional beams (5) comprises a support means and an actuation means. Support members (2, 32, 41, 51, 61) spaced about the longitudinal axis of the support means locally define an opening (4, 35, 43, 53, 63) for supporting a section of the beam (5). The position of adjacent openings (4, 35, 43, 53, 63) relative to one another defines the overall form of the beam (5) and the actuation means defines the position of each opening (4, 35, 43, 53, 63).

A pair of end securing devices are attachable to respective ends of the length of flexible spiral metal pipe. A mechanism moves the end securing devices relative to each other through a range of movement to an end position which effects bending of the length of spiral metal pipe to a desired angled configuration. Another disclosed method employs a preformed inflatable bladder which, when inflated, assumes the shape of an elbow. The preformed inflatable bladder is inserted in collapsed form into a length of flexible spiral metal pipe, and thereafter inflated.

  • Patent number: 6301947
    Abstract: A fluid level indicator that compensates for fluid temperature is provided. The indicator includes an elongated shaft that is received by the fill tube of the apparatus. The shaft is adapted to contact the fluid at one end to measure the level of fluid in the apparatus. A reversible liquid crystal display is carried by the shaft and includes a plurality of bands. Each band has a defined height and is capable of being illuminated when the oil is within a certain temperature spectrum. When the band is at a temperature within its spectrum, the band illuminates, or somehow differentiates itself from those bands that are not within their illumination spectrum. At a specific temperature, certain bands, adjacent to one another, are illuminated to create a vertical range on the dipstick. The desired level of fluid in the apparatus is defined by the vertical range created by the illuminated bands of the liquid crystal display.
