Title: Bonded knitting furnishing fabric of separate webs - from textured yarns shrinking when finished with bulky form stable weft
Inventor: FRIEDRICH EBERHARD
IPC: D04B1/14
Filed: 1980-06-21
Abstract: A furnishing fabric is produced by bonding together two separately running knitted lengths of material. The bonding is effected by means of stitches according to pattern. Between the points at which they are connected cavities are present into which a weft end is laid which does not form a stitch. At least two courses of stitches are present for the two separate layers in which a bulky, relatively formstable yarn such as union of cotton and wool, or of cellulose yarn, etc. is laid. Pref. the two separate lengths are knitted from textured, synthetic yarn which when the bonded fabric goes through the finishing process, shrinks. The number of courses for the upper layer is greater than the number of courses for the lower layer. To increase the quality of furnishing fabrics produced on knitting machines as compared with traditional goods. At the same time the price is reduced by the use of simple methods and cheaper yarns. The invention increases the cavities of the separate layers in size so that thicker yarn can be laid in, and the wave structure accentuated.

Title: Rotational distributor for oil mist
Inventor: WEHRFRITZ HEINZ DIPL ING
IPC: F16N7/32
Filed: 1981-08-11
Abstract: It has hitherto been difficult, when supplying a number of spindle systems of a machine with a lubricating oil mist, to supply all the bearings with the same quantity of oil per unit time. With a rotational distributor, the flow of oil mist is divided up in such a way that all the systems connected to it are connected cyclically to the oil mist appliance, while, for the remainder of the time, filtered air is used to convey the oil and seal off the bearings from the ingress of dirt originating from the air flowing out of the gap seals. The appliance consists of a housing (1) in which there is a rotating disc (2). The disc divides the housing into two chambers. One chamber (3) is supplied with oil mist and the other chamber (4) is supplied with filtered air. A distributor (5) with a hole allows the oil mist to flow from one chamber into the consumer line connected at any one particular time and simultaneously seals this line off from the chambers containing filtered air, from which the other consumer lines are supplied. <IMAGE>
