Abstract: Wires (D.4 to D.9) or objects similar to wires are fixed in predetermined positions by a device with pairs of clamping jaws (3.4/4.4 to 3.9/4.9). The device comprises at least two flat jaw elements (3, 4) lying against each other and being at least restrictedly slewable against each other around a center (M) and it further comprises holding means (20). Each of the jaw elements (3, 4) comprises one clamping jaw (3.4 to 3.9, 4.4 to 4.9) for each one of a plurality of fixing points arranged on a circle (K.3) around the center (M) which clamping jaws are designed for exerting tangential clamping forces directed tangentially to the circle (K.3) on wires (D.4 to D.9) fixed in the fixing points. Hereby, clockwise clamping forces are exertable with the one jaw element and counter-clockwise clamping forces are exertable with the other jaw element. By slewing the jaw elements (3, 4) against each other the pairs of jaws are opened and closed. With arrangements of fixing points which comprise a symmetry-plane (S) the jaw elements represent mirrored images of each other, i.e. they are identical and are arranged relative to each other withone of them turned by 180°.

Title: Providing timing to an external system
Inventor: MIMMI STEFANO
IPC: H04Q3/00
Filed: 1998-07-16
Abstract: Synchronizing a local timing unit to a central timing unit in a first switching system to determine the difference in timing between a connected external link and the local timing unit. This timing difference is then transmitted to the central timing unit which utilizes this information to adjust a frequency synthesizer that outputs the frequency of the external link to a second switching system. The local timing units are synchronized to the central timing unit via multiple timing paths set up through switching units within a switching network of the first switching system. The timing difference transmitted from the local timing unit is transmitted over a plurality of control paths through the switching units. Each switching unit switches one bit of data for each group of data being received on each of the external links connected to the first switching system. Any of the external links connected to the first switching system can be utilized to provide timing information for the second switching system.

Inventor: OLSON DARWIN
IPC: F16L37/098
Filed: 1998-10-29
Abstract: A quick-connect coupling for articulating hose lines includes a coupling body having a bore therein which receives a stem attached to a hose to be coupled to the body. A spline is positioned within the bore which receives a spline on the stem so that the stem does not rotate with respect to the bore and coupling body. A collet is provided which has inwardly and outwardly projecting detents that simultaneouslyengage both a shoulder within the bore and a groove in the stem to prevent axialmovement of the stem with respect to the bore. While the stem is thus retained within the bore, an O-ring seals with the surface of the stem. In order to disconnect the stem from the bore, a collet is pressed inwardly to disengage the detents and then the stem is pulled axially away from the coupling member. By providing a quick-connect coupling in which a stem does not rotate with respect to a coupling member, the collet which is used to lock or latch the stem and coupling member axially to one another is not worn and stressed by relative rotation between the stem and coupling member so as to threaten the integrity of the coupling.
