  • Patent number: 4712494
    Abstract: Automatic exchange of the size in an automatic sewing unit which comprises a sewing machine displaceable along two axes and a workpiece clamp group formed by at least two half-clamps, one of which is fixed and the other of which is mobile. In order to obtain different desired sizes, the machine, positioned at a basic size .phi. corresponding to the position .phi. of the axis, is automatically displaced in a positive way for reading the displacement made by the mobile half-clamp. The size is obtained as the difference between the trigger coordinate of a proximity fixed to the sewing machine and a memorized fixed coordinate corresponding to the basic size .phi..

  • Patent number: 4582468
    Abstract: A muffler for motor compressors comprising a body closed at the lower side by a cover and provided on its frontal wall with a hole through which the refrigerating gas is sucked. The gas introduced into the interior of the body strikes against the rear wall of the body and is diverted toward two narrow passages formed by the lateral internal walls of the body and by vertical walls of an M-shaped element located internally of the body. The inclined walls of the element favor the collection of the oil which has separated from the refrigerating gas and directs it toward an inclined plane which facilitates the discharge of the oil, by gravity, through a groove made in the body of the muffler.
