Abstract: The present invention relates to a process for production of aromatic polyimide film comprising (A) casting a dope containing an amide-type polar solvent and 10-45 weight percent of polyamic acid and having more than 0.4 dl/g inherent viscosity on a support, (B) concentrating the polymer content to be at least higher than that of the initial dope with simultaneous raising of the ring closure ratio to more than 30%, (C) removing the solvent from the film by extraction in an aqueous medium so as to lower the solvent content of said film to be below 10% and (D) then heating said film to more than 200°C. 
     The process of the present invention is useful for the production of aromatic polyimide film, with a reduction in the rate of solvent decomposition and improvement in productivity. 
     The aromatic polyimide film produced by the process of the present invention is superior in thermal as well as mechanical properties and is highly useful as an electric insulation material and also as a base for flexible printed circuits, magnetic tape, etc.

Abstract: Engine parameters are detected to set a basic ignition timing, and this basic ignition timing is forcibly changed to effect feedback control in which engine output is detected for finding an optimum combination of ignition timings of the individual cylinders. Engine is operated with a plurality of different ignition timing combinations, where the number of the combination equals the number of the cylinders added by one. The engine is further operated with one of the ignition timing combination so that the engine is operated twice with an identical ignition timing combination. As a result engine output change caused by factors other than ignition timing change is detected. Thus, one of a plurality of ignition timing combinations, which gives the lowest engine speed only because of the change in ignition timing is found and is replaced with a new ignition timing combination with which the engine produces higher output. The replacement is carried out selectively in accordance with the variation in engine output data resulted from various ignition timing combinations. An average value of various ignition timing combinations is used to renew the same. In this way the ignition timing combination is renewed successively for finding the optimum ignition timing combination.

Abstract: In a prophylactic method for cleaning and disinfecting a contact lens, the lens is contacted for an extended period, typically up to 10 hours, for example 5 to 10 hours, with a solution containing hydrogen peroxide. The contacting is effected in the presence of a solid sustained release composition which slowly liberates a peroxide inactivator and which maintains its integrity over the extended period. The solid composition liberates sufficient peroxide inactivator such that substantially no peroxide remains in contact with the lens at the end of the extended period. The lens may then be contacted with a contact lens wetting or comfort solution before insertion into the eye.

Abstract: Coal is gasified in the plant which also includes a treatment for the purification of the high-pressure crude gas. In general, the crude gas is purified by wet scrubbing. However, this type of purification entails a substantial lowering of the crude gas temperature and hence a loss of energy. This is a disadvantage particularly if the crude gas is to be charged to the combustion chamber of a steam generator. By contrast, the invention now proposes that the equipment serving for the purification of the crude gas has at least two parallel-arranged cyclones on the inlet side, which can be connected or disconnected individually. Dry purification of the crude gas thus takes place at an at most small temperature loss, and the gas rate corresponding to the best possible degree of purification can be adjusted by the particular number of cyclones put into operation to the gas rate actually leaving the gas generator or to the gas rate in fact required for charging to the steam generator, without the need for the insertion of buffer capacities.
