Title: Joining polyolefin pipe to connector - by cold expanding end of pipe with inner dia., smaller than outer dia. of connector fitting over connector, etc.
Inventor: IMGRAM FRIEDEL
IPC: F16L47/20
Filed: 1990-08-16
Abstract: Pipes are joined in a process in which one end of a polyolefin pipe is expanded and fitted over a connecting piece. The end, whose i.d. is smaller than the o.d. of the connector, is reversibly expanded at room temp. by means of a spreader mandrel to an i.d. greater than the o.d. of the connector; the spreader is removed and the pipe and connector are fitted together, after which the connector is attached formly to the pipe by reversing the expansion. Medium density and crosslinked polyolefins in partic. are cold formed and they tend to revert to their original shape. The expanded pipe therefore shrinks back again. It does so relatively quickly. Moreover the shrinkage causes the polymer to adapt itself to such features as beads, dimples, grooves etc..  Clamping ring of such reversibly formed polymer can also be fitted over the end of the pipe in the same way. Equally an e.g. metal clamping ring is used conventionally. ADVANTAGE - Produces tight joints at room temp..

Title: Polyurethane foam mouldings for painting - produce surfaces free from defects if coated with resin which cures in presence of hoisting and only then given paint coating
Inventor: LINK GUENTHER DR
IPC: B05D7/02
Filed: 1990-11-22
Abstract: A plastic moulding made of high density foam, and RRIM polyurethane in particular, is suitable for painting; before being painted however the moulding is coated with a material which cures in the presence of moisture.       A coating which cures in the presence of moisture normally sets hard in 3-4 hrs. at room temp.; it forms a sealed coat which allows the product to be handled normally and even to be repainted and oven-cured. Consequently any air entrapped in the basic moulding is enclosed by the impervious coating. It is not necessary to wait 8-10 days before coating. The coating need not be applied to the whole surface but merely to the areas where the surface has impressions, recesses, etc.. If the final prod. is damaged in its surface it can be abraded and coated again with the same moisture-curing material.       ADVANTAGE - The mouldings can be painted without showing the surface defects which normally arise such as pores, pits, blisters etc.. (Dwg.0/0)

Title: Adhering twin data disk - using adhesive ring on inner side of one disc spread out by centrifugal force after second disc is placed on it
Inventor: KALLIS JUERGEN
IPC: G11B7/26
Filed: 1990-12-21
Abstract: To bond together two data disks, to form a twin disk, adhesive is applied in a ring pattern to the inner side of one disk (1). The inner side (9) of the second disk (8) is applied to the adhesive-coated inner side (5) of the first disk (1) to make up the twin disk. Both disks (1,8) are rotated at a sufficiently high speed to disperse the adhesive between them in a radial direction to the outer edges (2) of the twin disk. The ring of adhesive applied to the inner side (5) of the first disk (1) is spread out into a ring band (7) by disk (1) rotation, to about half way across the disk to give a ring (7) width of 1.5-3.5cm, through adhesive application while the disk (1) is rotated at about 20-40rpm. When the disks (1,8) are brought together as the twin disk, they are both rotated at 4000-6000 rpm to spread out the adhesive between them. ADVANTAGE - The bonding adhesive is distributed evenly between the two disks making up the twin disk and, through the centrifugal dispersion of the adhesive between them, the twin disk is automatically balanced.
