Title: Small metal pipe-bending machine - has die in sections curving to lesser radii than finished article
Inventor: KIMURA SADAO
IPC: B21D7/02
Filed: 1990-01-02
Abstract: The machine bends small-diameter thin-walled metal pipe, having a stationary die in a large number of sections, of the shape to which the pipe (2) has to be bent. A first section of the die has curves in the lengthwise direction of radii less than those to which the pipe is to be bent and a surface at right angles to the bending direction. - A second section has a guide face (1") parallel to this direction.

Inventor: DARLING DWIGHT
IPC: G04B19/22
Filed: 1990-09-28
Abstract: A device for determining the time anywhere in the world, in any selected geographical area. A circular map is positioned on a frame and may rotate relative to the frame, the map being a south pole projection of the world. The map rotates about its center point, corresponding to the south pole. An annular band having twenty-four evenly spaced first time zone positions is provided on the frame beyond the outer boundary of the map, outwardly concentric with the map. A circumferential ring zone having twenty-four evenly spaced second time zone positions is provided on and around the perimeter of the map concentric and inbetween the circle defined by the first time zone positions and the map. Each first and second time zone segments corresponds to a distinct hour of a twenty-four hour day. Land areas of the map are visually coded in 24 distinct geographical time areas (for example, colour coded), according to their local time. Each second time zone sector is visually coded to correspond to a distinct geographical time area. The device may be operated manually, or may use a clock mechanism. The hour hand and the map rotate together. For re/setting the zone, a stop mechanism holds the map in place while the hour hand may be rotated counterclockwise. To re/set the time, the map and the hour hand are rotated clockwise and should be positioned for aligning the second time zone sector, associated with the selected geographical area, with the corresponding first time zone segment, according to the local time of the selected geographical area. Further, by associating first and second time zone positions and corresponding land areas by means of the visual coding, an identification is made of the distinct hour, minute and second relative to the selected geographical area (selected land area).
