    摘要: A process for the continuous and discontinuous production of tetrahydrofuran polymers by homopolymerizing tetrahydrofuran or copolymerizing tetrahydrofuran with 1,2-alkylene oxides in the presence of compounds with reactive hydrogen or carboxylic acid anhydrides on an acid-treated, calcined and granulated aluminium silicate catalyst which may consist of amorphous aluminium silicate, a zeolite or kaolin. By keeping the concentration of carboxylic acid anhydride or alkylene oxide constant below 1 wt. % in the polymerization recipe throughout the polymerization it is possible to largely prevent the formation of cyclic ethers and to obtain a polymer with a very narrow molecular weight distribution. In granular form, the catalysts exhibit a hitherto unknown activity and form polymers with a very narrow molecular weight distribution and low color and acid numbers.

    摘要: A circuit arrangement for the implementation of a fast discrete Fourier transform in real time through the controlled operation of cross-linked butterfly, or kernel, operators. The circuit arrangement will successively transmit the two halves of a sequence of complex input words through a series-parallel input register and an interim data storage to a plurality of butterfly operators which operate in parallel, whose outputs are switchable by a multiplexer for recursive linkage with the interim storage or, in essence, for the delivery of the frequency range-output words to a parallel-series output register.

    摘要: A star-shaped array of channeled rolls in a rolling mill for rolling bar stock has the rolls pressed together with a pressing force exceeding the rolling force by a prestressing force sufficient to cause frustoconical flanks of the rolls to forceably press against one another. This stabilizes the rolls and also permits a fine adjustment of the diameter of the passage defined between them.

    摘要: The shutter mechanism includes an aperture-unblocking member mounted for movement between an unactivated aperture-blocking position and an activated aperture-unblocking position. A cocked drive mechanism is coupled to the aperture-unblocking member and is operative when released for moving the member from the unactivated to the activated position. An inertial braking mechanism is driven by the drive mechanism when the latter moves the aperture-unblocking member to the activated position, and is operative during such movement for applying to the drive mechanism an inertial braking force slowing the movement of the aperture-unblocking member to the activated position. The drive mechanism includes a drive cam, and the inertial braking mechanism includes a driven cam. The surface of the drive cam bears upon the surface of the driven cam and transmits to the driven cam the drive force by means of which the drive mechanism drives the inertial braking mechanism. The cams are so configured that, as the drive mechanism drives the inertial braking mechanism, the surface of the drive cam rolls along the surface of the driven cam.
