Title: Indirect extrusion process and machinery therefor
Inventor: STEWART CHARLES L
IPC: B21C35/06
Filed: 1987-03-04
Granted: 1995-02-14
Abstract: An indirect extrusion process, and apparatus therefor, for producing an extrusion product from a hot metal billet. A press container is mounted to be substantially axially stationary during extrusion of a billet. A hot billet, a die and a pressure disc are located into the axial throughbore of the container so that the billet is sandwiched between the die and pressure disc, with the pressure disc having a maximum outer diameter between opposite radial faces which is slightly less than the diameter of the axial throughbore to define a diametrical clearance between the pressure disc and the press container. A bolster is located adjacent the pressure disc and is axially fixed to substantially prevent axial movement of the pressure disc in a direction toward the bolster during extrusion. The bolster exerts a relatively insigificant axial force against the container. An elongated stem having an axial passage is moved into the throughbore of the container to press the die toward the bolster, causing the billet to be extruded through the die to create an extrusion product which exits the container through the axial passage in the stem, while extrusion of the billet through the diametrical clearance between the pressure disc and the container is substantially avoided.

Title: Method and circuit concerning the resolution of digital signals
Inventor: HARTNACK WOLFGANG
IPC: H04N19/60
Filed: 1988-08-24
Granted: 1998-04-28
Abstract: In digital signals transformed into a frequency domain, inaccuracies occur in the structure of the reproduced video signals due to rounding errors in the calculation of the coefficients with a shortened number of digits. 
<??>The invention provides a remedy in that the range of numbers of the direct component is transferred into the range of numbers of the alternating components and thus a greater range of numbers is available for the alternating components for the common processing of the direct and alternating components. 
<??>The invention can be used in digital systems with block-by-block processing in which a rounding of the spectral coefficients is carried out due to a limited number of bits in the calculation.

Abstract: The stabilized sodium percarbonate is produced by (a) introducing 4kg/hr sodium carbonate and 40g/hr sodium methane silicate, and 3.2kg/hr hydrogen peroxide containing 25g magnesium sulfate and 10g polyphosphonic acid to the 10L reactor, and then reacting them at 50 deg.C., 3 rpm agitating velocity and 70L/min air velocity, and (b) drying the stabilized sodium percarbonate by the fluidized bed dryer at 130 deg.C. and 30cm fluidized bed height, and then cooling it at 60 deg.C. The stabilized sodium percarbonate is used as a nonpollutive bleaching agent.

Abstract: The method for sensing the appearance of the object as well as its moving direction includes the steps of: a) storing the data converted from the optical signal detected by the receiver in the preset memory region; comparing the data generated on the next period with the stored data to see whether they matches within the preset region; and c) replacing the present stored data with the next one if they matches, but providing the alarm for indicating the object appearance if not.
