Filed: 2023-02-20
Granted: 2023-11-23
Abstract: Weed seeds are destroyed in the chaff from a combine harvester by 
repeated high speed impacts caused by a rotor mounted in one of a pair of side by 
side housings which accelerate the discarded seeds into contact with stator bars 
5 at angularly spaced positions around the axis of the rotor. The stator bars are 
formed from bent sheet metal which are L-shaped or U-shaped in cross-section to 
define a first leg lying in a cylindrical surface surrounding the axis of the rotor and 
a second leg extending outwardly from the cylindrical surface connected to the first 
leg at an apex at a leading end of the first leg relative to the direction of rotation of 
10 the rotor. When U-shaped, the bars are symmetrical and can be reversed when 
the second leg is worn for extended life.

Abstract: The invention relates to a method for the recovery of carbon and combinations of hydrocarbons from discarded tyres or similar polymeric material by pyrolysis, using a reactor (3) in which the material is placed in a preferably largely fragmented condition, whereby the material is heated to pyrolysis temperature by the recirculation of previously formed and heated pyrolysis gas which is led through the material and where the pyrolysis gas obtained in this way is brought to condense to condensable products in a condenser (8) connected to the reactor. In order to improve the possibilities of control of the process of pyrolysis, a reactor is used with an inlet (6) and an outlet (7) so that a gas can be led through the reactor (3) passing over the polymeric material which is placed in it, whereby at least a part of the pyrolysis gas which does not condense in the condenser (8) is heated to a predetermined temperature and is led by recirculation in a circuit through the reactor for heating the polymeric material placed in it.

Abstract: An apparatus and method generate a linearly modulated signal in a polar modulation system. A signal for transmission is separated into a phase component and an amplitude component, and a carrier signal is modulated with the phase component in a phase modulator, creating a phase distortion. A compensator compensates for the phase distortion created by the phase modulator by modifying the amplitude component. The phase modulated carrier signal is amplitude modulated by the compensated amplitude component to produce a linearly modulated signal.

Abstract: A small footprint device can securely run multiple programs from unrelated vendors by the inclusion of a context barrier isolating the execution of the programs. The context barrier performs security checks to see that principal and object are within the same namespace or memory space or to see that a requested action is authorized for an object to be operated upon. Each program or set of programs runs in a separate context. Access from one program to another program across the context barrier can be achieved under controlled circumstances by using a global data structure.

Abstract: The invention relates to a method for the disposal and the utilization of waste products of any kind. According to the inventive method, industrial, household and/or hazardous wastes that contain unsorted, untreated, harmful substances of any kind in solid and/or liquid form, as well as wracks of industrial commodities are subjected to a step-wise thermal treatment and thermal separation or physical transformation. The solid residues obtained by this method are liquefied at high temperatures. The inventive method is further characterized in that the discharged synthesis gas, once it has left the high-temperature reactor, is subjected to a shock treatment with water to cool off to 150  DEG C to 200  DEG C and then to a second shock treatment with water until it is cooled off to less than 90  DEG C. After the first step, the batch contained in the synthesis gas is transformed to hydrogen sulfide in the presence of water vapor and the hydrogen sulfide is then removed by means of iron chelate in a gas purification step.
