Abstract: A fixation element and a method for producing such fixation elements for a vibration-insulating assembly of a first component 20 upon a second component 19 is disclosed. The fixation element comprises bearing plates 10, 11 which are positioned at a distance axially spaced from each other and which have projecting snap-in members 13, 18 which are intended to engage corresponding openings defined within each component 19, 20, so that the two components are made to bear in a stable manner against the bearing plates 10, 11. In this respect the snap-in members 13, 18 form an integral part of each bearing plate 10, 11. Moreover, the plates are mutually connected by means of a bridging part 12 of elastomeric plastic material. According to the method, the bearing plates are cast as a single piece 21 within a first casting mold, such that they are connected by at least one breakable bridge 22. The single piece 21 is placed within a second casting mold consisting of two halves 23, 24.

Abstract: There is described a substantially cylindrical screw grommet capable of accepting a threaded fastener driven obliquely with respect to the axis of the grommet, the exterior surface of the grommet being formed with axial rows of spaced barbs, the rows being separated by flutes, and the grommet being further formed with a bore which has a first cylindrical portion intermediate the length of the grommet, a first tapered portion connecting the first cylindrical portion to a second cylindrical portion of smaller diameter, and a second tapered portion of the bore diverging from the second cylindrical portion and terminating at one end of the grommet.

Abstract: A valve for regulating the flow of fluid in a motor vehicle heater system, the valve having a housing with coaxial inlet and outlet ports and a quadrantal closure member pivotally mounted in the housing for movement between open and closed positions, the closure member having an aperture coinciding with the outlet port when the closure member is in the open position and a thin flexible portion covering the outlet port when the valve member is in the closed position.

Abstract: The invention concerns a child-proof door catch device which requires a sequence of unconnected manipulations to operate the mechanism opening a door. The mechanism includes a housing and operating and latching elements, the operating and latching elements being normally held apart by a biasing means. When the correct sequence of manipulations is performed on the operating element, the latching element is caused to disengage from a striker plate to allow the door to be opened.

Abstract: Polythene bags are used to group together articles of clothing for transit. The invention relates to a security seal for use with such bags to prevent undetected transit theft. The seal according to the invention has two strip-like portions, which are formed with latching portions at points along the lengths of the strip-like portions. The seal is applied to the neck of the polythene bag, and during application the latching portions pierce the bag and pass through to engage in pairs with latching portions on the other strip-like portion. The latching portions have a weakened section, which breaks if the latching portions are urged out of engagement, thus a bag once sealed cannot be opened undamaged, as the seal will have broken latching portions indicating to a checker at the destination that the bag has been interfered with.
