Abstract: The invention refers to an automatic controlled aerating and humidifying device and for a creel with yarns directed to a textile machine. The invention includes an air conditioning unit (12) in coaxial position to a frame (10) carrying yarns and which is equipped with a device (17, 17a) to receive clean and humidified air coming from a centralized generator of fresh and humidified air and to supply it from one end to another end towards or through yarn bobbins or reels, and with a device (18) defining a chimney-like passage to suck used and dirty air from the bottom and move it away towards a filtering device.

Abstract: To cover the energy needs of animals, in particular domestic animals, including ruminants, relatively large quantities of fat can be fed in a completely absorbable form without disturbing the animals' digestive processes. The fats are chosen from readily available sources such as lard, tallow, fish oils, and the like, and preferably have the following spectrum of fatty acids:______________________________________ C.sub.4 -C.sub.12 3-5% C.sub.14 1-2% C.sub.16 20-25% C.sub.16-1 1-3% C.sub.18 20-30% C.sub.18-1 35-50% C.sub.18-2 0-1% C.sub.20 1-2% ______________________________________If a selected fat has a melting point below the body temperature of the animal to be fed, the fat is hydrogenated to raise its melting point above the body temperature of the animal and is converted preferably by means of a cold-air crystallization process, into a structure of fine particles of a maximum size of 50 .mu.m.

Abstract: A thread delivery apparatus for textile machines comprises a pair of nested wheels inclined one relative to the other for accepting multiple turns of yarn. Instead of the axes of the wheels passing each other with a finite minimum spacing as with nested godet wheel frames, the axes (18, 19) are in a common plane and intersect at a point (20) outside the thread control zone in the plane of a centering disc (23.1) fast on one of the wheels. The drive is transmitted from one wheel to the other through the centering disc.
