摘要： This invention relates to a process for the preparation of polyurethane foams by the reaction of a foamable reaction mixture. A liquid blowing agent is added to either the isocyanate or the polyol prior to mixing of the components. An inert gas is dispersed in the component which contains the blowing agent and the gas charged component is immediately and continuously mixed with the other component, at the same time keeping it at least under the pressure required for charging it with gas until mixing has been completed, and leaving the resulting reaction mixture to foam up. The key to the present invention is in the small amount of gas charging.

摘要： A shifting mechanism for reverse drive that slows the input shaft of a manual transmission in which a reverse gear wheel is shifted into engagement with reverse drive gearwheels disposed on a constant mesh gear and an output shaft. In order to slow the input shaft with the clutch disconnected, a shift fork is located on a rotatable and displaceable gear selector shaft that carries a shift finger and shift forks displaceably thereon. The shift fork is axially displaceable against the force of a spring relative to a bracket arm connecting the fork to the shift finger. An axial cam cooperates with an inclined portion of the shift fork and two radial arms contact stop surfaces on the housing cover and on an arm of the shift fork.

摘要： The present invention relates to a method for controlling the temperature of a system in accordance with a desired temperature curve which is divided into predetermined time intervals. It is the object of the present invention to control the temperature of the system in such a manner that the predetermined and desired temperature curve is observed as exactly as possible. The temperature control method is characterized in that the heating power to be applied to the heating device during one time interval is determined in response to the desired temperature and the heating-up rate of the respective time interval by using empirically determined dynamic heating-up and cooling characteristics typical of the system, that the heating power determined for each time interval is converted according to a calibration curve into a set value for a voltage control device, that the heating power actually applied to the heating device is determined within each time interval, said heating power having assigned thereto a set comparative value by means of the calibration curve, and that, when the set value deviates from the set comparative value by more than a predetermined and set tolerance value within the respective time interval, the set value of the respectively successive time interval is changed in response to said deviation.

摘要： This invention relates to a process and a laminator for the continuous production of laminates of foam with facings. An upper facing and a lower facing and a web of meshwork are introduced into the foaming space of a laminator and a fluid reaction mixture is spread over the lower facing before it runs into the foaming space. The reaction mixture penetrates the web of meshwork as it foams up on its journey through the foaming space and becomes bonded to the facings.

摘要： The invention relates to equipment for the continuous production of foam boards, which may be laminated between facings, from a liquid foamable reaction mixture. The apparatus broadly comprises(i) a conveyor,(ii) an inclined table at one end of said conveyor, the incline of said table sloping downwardly toward said conveyor,(iii) a foam mixture application device located above said downwardly sloping surface, and(iv) a transverse foam mixture distribution device located downstream of said application device and located above said downwardly sloping surface thereby forming a space therewith. When sheets or relatively thin foam boards or sandwich boards are produced, the device used is generally additionally equipped with an upper conveyor. This invention primarily relates to such double conveyors. The liquid reaction mixture must be applied over the entire width in a particularly uniform layer in order to obtain a perfect final product. The device of the invention can also be used for the continuous foaming of buns.
