Title: Shredding machine
Inventor: FREY OSCAR M
IPC: A01F29/00
Filed: 1987-06-18
Granted: 1992-01-28
Abstract: IMPROVED SHREDDING MACHINE                 Abstract of the Disclosure The machine disclosed is for shredding a cylindrical hay-bale. The bale (39) is rotated about its cylindrical axis (36), and is engaged tangentially by a rotary cutter (38) with centrifugal blades (52). The bale is rotated, not by the usual conveyor or drive belt but by discrete rollers.          The machine has three roller (43) on the leading side of the cutter, and one roller (45) on the trailing side. The rollers are provided with bale-engaging teeth (72,76). The leading rollers and the cutter are positioned underneath the bale, for gravity-assisted engagement with the bale. The rotary cutter has shredder-blades (52) presented edge-on to the hay, which keeps the shredding forces low; hence, the rollers can be allowed to jam-feed the bale into the cutter, which keeps the bale moving even if the bale should contain eg. a lump of ice.

Abstract: Abstract Of The Disclosure A press apparatus is disclosed for removing fluid from a fibrous web.  The apparatus includes a press member and a blanket cooperating with the press member for defining therebetween an elongate pressing section such that the web is pressed between the press member and the blanket during passage through the pressing section.  The blanket is urged towards the press member such that when the web passes through the pressing section, fluid is pressed from the web. A heating device is disposed adjacent to the press roll for transferring heat to the web such that when the web passes through the pressing section, the web is subjected for an extended period to increased pressure and temperature so that water vapor generated within the pressing section during the passage of the web through the pressing section forces the fluid in the liquid phase away from the web.

Abstract: ABSTRACT OF THE DISCLOSURE           A process is described for producing unique and novel sulfonate containing terpolymers of water soluble monomers with water insoluble monomers which are efficient viscosifiers of aqueous and brine media.          The process relies on the complete solubilization of the water insoluble monomer by means  of a dilute solution of a suitable water soluble surfactant.  The type and concentration of surfactant are chosen to produce a clear, uniform, homogeneous aqueous disper-sion of the hydrophobic monomers in the presence of both nonionic and anionic water soluble monomers and, in addition,  the reaction medium remains a clear, uniform, homogeneous mixture with no phase separation as the reaction proceeds to completion.  The micelles formed by the surfactant are small aggregates, con-sisting of on the order of 50 to 200 molecules.  They are stable toward phase separation and effectively disperse the water insoluble monomer on a very fine scale so that the terpolymerization is effected without the formation of latexes or fine particulates of water insoluble polymer.

Title: Friction device for the setting process in projectile fuses
Inventor: WINTERHALTER WALTER
IPC: F42C9/00

Granted: 1992-08-04
Abstract: ABSTRACT          In a fuse for projectiles a setting ring is rotatably disposed about the longitudinal axis of the fuse, through which the ignition time or delay time can be set exactly.  To prevent the inadvertent resetting of the setting ring once set, said setting ring is secured by a friction system formed from a fric-tion ring with friction nut impinging on it.  By means of the friction system that can be placed in positive locking fashion on the lower fixed housing part of the fuse the  time adjustment torque usual in time fuses can be set in a simple manner and at the same time a positive connection of the housing parts is achieved.

Abstract: ABSTRACT OF THE DISCLOSURE          A method for the manufacture of film from blends of polyolefins is disclosed.  The blend is comprised of a polyethylene and up to 20% by weight of the blend of a polyethylene grafted with 0.5 to 2.0% by weight of an ethylenically unsaturated carboxylic acid or anhydride, especially maleic anhydride.

Abstract: ABSTRACT OF THE DISCLOSURE      The weight  of least mean square (LMS) adaptive filter are updated with a different set of taps than are used to form the output of the adaptive filter in the adaptive processing device of the present invention.  As a result of performing the multiplications and sums required for the filter operation simultaneously, an integral number of clock cycle delays appear in the narrowband and error feedback channels.  The number of taps of the tapped delay line of the invention are increased, whereby the increased delay through the delay line may be used to compensate for a delay through the filter of an integral number of clock delay cycles.      Instantaneous weight updating in accordance with the signal being utilized, may then be achieved at a clock rate frequency that is ten times or more greater than prior art adaptive filters.

Abstract: ABSTRACT OF THE DISCLOSURE         A process of treating meal containing vegetable proteins is disclosed.  This process includes the step of extracting the meal with a suitable aqueous solvent in which the vegetable proteins are soluble to obtain an extraction solution. The solubility of the dissolved protein in the extraction solution is then adjusted to precipitate at least some of the protein and therefore obtain a precipitated protein fraction and an unprecipitated protein fraction in solution.  The precipitated protein fraction is then separated from the protein fraction in solution, and the unprecipitated protein fraction is separated from the undesirable components in the solution by membrane processing.  Each of the protein fractions is then suitably dried to recover the proteins.

Abstract: ABSTRACT            A  line  build  out  comprises  a  control  voltage  mechanism for applying a control voltage to a tuning diode or varactor.  The control  voltage is generated so as  to be  indicative of  the length of a cable over which  the signal  has  traveled.   The capacitance  of the  tuning  diode  or  varactor  is  changed according to the control voltage.  A resistor is connected to the cathode of the tuning diode or varactor and a capacitor is connected  to the anode of  the  tuning diode or  varactor.   A signal can be measured at the cathode which corresponds to the incoming signal and has been attenuated by frequency roll-off in accordance with  the  length  of  the  cable  over which the signal has traveled.  In this way, attenuation for signals over cables of various length can be equalized in a manner which not only takes into account the length of the cable, but also the frequency of the signal.

Abstract: Abstract of the Disclosure Electroluminescent phosphors, electrolumi-nescent panels and lamps made with such phosphors, and a process and apparatus for treating phosphors are disclosed in which the phosphor particles (50) are coated with a very thin coating (80) of SiO2, to protect the phosphor particles from aging due to moisture intrusion.  The phosphor particles are coated in a cold wall reactor (10) by the pyrolytic decomposition of silane in the presence of heat and oxygen to a coating thickness of approximately between 0.1 and 3.0 microns.  The apparatus and method of coating includes the placement of a quantity of phosphor in a cup-shaped heated reactor bowl (30) and subjecting the particles to a temperature of about 490°C and an atmosphere of silane and oxygen, while continuously mechanically agitating the particles with a blade (44) in which the particles are continuously rotated and turned so as to expose the surfaces of the heated particles to the reaction atmosphere.  Panels and lamps made from such phosphors may be die cut and trimmed, have an increased life as compared to panels and lamps made with untreated phosphors, and exhibit a minimum of color shift during the lifetime of the panel.
