Abstract: A high frequency noise suppressor for engagement around a cable comprises a pair of case halves made of nylon  or  other  rugged  synthetic material  which  can  be snapped around  a  cable in clam shell  like fashion.   A ferrite core half  is positioned in  each case half for defining a ferrite core member  around  the cable.   Each case  half  has  opposite  end  walls  with semicircular recesses.  A plurality of triangular fingers extend into each recess and are positioned at a slight angle outwardly with  respect  to  an  interior  of  each  case  half.

Title: Hinge with spring coupling member
Inventor: BRUESTLE KLAUS
IPC: E05D5/02
Filed: 1991-05-07
Abstract: A hinge includes a hinge arm mounted on a base plate by an intermediate member having a U-shaped cross-section.      The hinge arm is retained on the intermediate member by depth and joint adjustment devices, e.g. clamping and adjusting screws. Retaining elements of the intermediate member engage corresponding retaining elements of the base plate at two points staggered over the length of the base plate. The retaining elements are rigid at one such point, and at the other point one retaining element is resilient.      The hinge arm and the intermediate member engage the base plate with the rigid retaining elements, and snaps in at only the base plate due to the resilient retaining element, which is in the form of a leaf spring. At the rear end the intermediate member is provided with a bridge which defines a gap into which is inserted the leaf spring. A flap is punched from the leaf spring and engages in a recess of the intermediate member arranged underneath the bridge, thus locking the leaf spring to the intermediate member.

Title: Method for manufacturing of organic fertilizers and device thereof
Inventor: INOUE SATOSHI
IPC: B01F7/00
Filed: 1990-06-26
Abstract: The present invention relates to a method for manufacturing of organic fertilizers by composting within a short time ,treating mixture of livestock excrements, such as chicken-, cattle- manures with cellulose-containing organic materials such as grasses, hulls, straws, wood chips, etc, into organic fertilizers, and a device for performing said method.      The method is characterized by adjusting moisture content, to a range of 25% - 75 wt%, of said mixture, cutting and kneading of the mixture under an elevated pressure until the temperature thereof goes up to 40°C - 90°C by the elevated pressure and friction, releasing them from the state of elvated pressure, followed by contacting them with air homogeneously by pulverizing the thus-treated mixture while contacting with air.        By practicing said steps, microorganisms in the treated materials are activated because of physical and thermal stimulations, by which fermentation is highly enhanced, therefore, composting is accomplished within very short time, and homogeneous fertilizers of good quality are obtained.        In the present invention, fermentatio is accelerated by adjusting pH of said mixture with a pH adjusting agent in order that pH value thereof during fermentation stays in a range of pH 6 - 9.        Such organic fertilizers can be produced by using a device for manufacturing of organic fertilizers characterized by connecting the front end of a cylindrical primary treatment tank which is equipped with a hopper for feeding of raw materials on the rear end, to the rear end of a cylindrical secondary treatment tank which is equipped with an opening for taking out of products, through an open/close gate, wherein said primary treatment tank is equipped with a screw conveying system and a cutting/ kneading system inside, and said secondary treatment tank is equipped with rotary blades for fine cutting inside.
