Abstract: CASTELLATED SPOOL FOR ELECTROMAGNETIC BAND CLUTCH        ABSTRACT OF THE DISCLOSURE         An electromagnetic clutch for a vehicle engine cooling fan includes a driving member mounted for rotation by the vehicle engine and a driven member rotatably mounted on the driving member.  The driven member carries the engine cooling fan.  One end of a band is connected to the driven member, and wraps circumferentially around the driving member in the direction of the rotation of the latter.  An electro-magnetic coil comprising windings wound circumferentially around the driving member and rotatable therewith exert an electromagnetic force on the band when current is transmitted to the coil, drawing the band into engagement with the outer circumferential surface of the driving member, to thereby engage the clutch and cause the engine cooling fan to be rotated with the driving member.  The radial outer edge of the spool, which is engaged by the band when the clutch is engaged, is provided with alternating castellations or projections which cooperate to define a gap having segments extending obliquely with respect to the edges of the spool.  Accordingly, the contact area is distributed across the band instead of being concentrated along the edges of the band, thereby substantially decreasing wear on the band and thereby increasing its useful life.

Title: Packing laminate provided with crease  lines

Granted: 1983-08-09
Abstract: ABSTRACT            A packing laminate which is intended to be converted into packing containers is often provided with crease lines in order to  facilitate folding and shaping. At the places where crease lines cross each other a multiple folding of the laminate takes place on conversion into packing containers which, among other things, means that small cracks are formed in the different material layers, so that the tightness of the packing container  is put into jeopardy. In accordance with the invention, a packing laminate is proposed in which these difficulties are overcome in that the laminate is provided with specially designed auxiliary crease lines which in the region of the laminate, where the folding lines cross each other or meet, replace the (main) crease line guiding the folding line. The auxiliary crease lines are situated at such a distance from the main crease line that the folding line is not affected, that is to say, the folding line will after folding not coincide in any part with the auxiliary crease lines. The auxiliary crease lines will merely be situated on either side of the folding line in such a manner that the take up and guide the crease formation or "wrinkling" which normally arises in the inner laminate layer in the folding line itself.
