Abstract: The process consists in producing construction structural elements (7) whose internal volume is partially occupied by an elastomer material reduced in volume by compression. It is particularly suitable for using, for this purpose, casings (3) of tires that are no longer usable. The casings are reduced to pieces (3') and conveyed into a press (4) that performs their compression to reduce the volume 87%. Packages (3'') thus compressed are blocked in this situation by ties (6') or vulcanization and then inserted in a form (9) for concrete provided with the necessary reinforcement (7''). When the filling of the form with concrete (7') is performed and the setting has occurred, a lightened element (7) is obtained provided with a relative elasticity. The process also achieves the important result of obtaining the elimination, without pollution, of tires no longer recyclable. <IMAGE>   <IMAGE>

Abstract: A dewatering device for the web-forming or wet section of a papermaking machine comprises foils arranged transverse to a forming wire, that is to say, extend in the cross-machine direction. Force or powering elements act upon the foils so as to exert a force or pressure upon the forming wire, and thus, bring about dewatering and sheet formation of a layer of fiber stock suspension reposing upon the forming wire. The force elements are constructed and positioned such that additional moments are generated which counteract tilting moments produced by the frictional force present between the foils and the forming wire. In certain arrangements, the force elements also can be interconnected with one another.

Abstract: A method of manufacturing high-strength, cold-rolled steel sheet excellent in formability. When increasing the strength of extra low-carbon steel as a base material including Nb or a combination of Ti and Nb by adding solid-solution strengthening element thereto, quantities of P and Si to be added which have been used in quantities are decreased whereas Mn and Cr are liberally added. Thus, the yield strength is prevented from increasing and the strength can be increased, whereby a high strength cold rolled steel sheet excellent in surface formability and in resistance to denting can be manufactured.

Date Jan. 7, 1993.A system for measuring the "time of flight" or transfer time of a sound wave in a gas by using the relation between the gas temperature and the velocity of the sound wave in the gas, and calculating therefrom the temperature of the gas. The system comprises an emitter, which generates a sound which is coherent in phase, at one frequency or a group of frequencies; a self-correlating decoder and a receiver, which is associated with the emitter, and which sends the sound to a filter system and to an assembly controlled by a microprocessor, which processes the signal coming out of the filter system in a shape similar to a Hamming wave shape in order to determine the absolute maximum value and therefrom determine the transfer time. With this knowledge, it is easy to relate the transfer time to the distance traveled between the emitter and receiver and the known properties of the gas, in order to arrive at the temperature of the gas through which the sound has been sent.

Abstract: A Doppler control circuit for a CW or pulse Doppler radar system for monitoring not only the phase shift between echo signals from several targets but also the amplitude difference between the several targets and to further tune the radar to a particular target among one or more targets from which echo signals return. The control circuit can be used in state of the art CW or pulse Doppler type radar systems. In a further system, a continuously generated radar signal is repeatedly transmitted at different frequencies in time division fashion to define a succession of transmit and receive frames. The receive frames are divided into a plurality of time interval windows with selected windows being used to detect received signals at the different frequencies. The remaining windows can be used for subsystems of the radar system. The rate of phase shift of received signals at a reference frequency is used to determine closing rate (positive or negative) while the phase shift difference between received signals at two frequencies is used to determine range and target direction. In yet a further system, a special circuit is provided for conditioning selected portions of the Doppler frequency spectrum to attenuate or de-emphasize portions of the echo signal corresponding to selected targets in the radar system environment, such as rain or stationary wayside objects, in order to give such echo signals less weight in determining roadway hazards.
