Abstract: ABSTRACT          A digital processor including both macro and micro instruction generators.  The micro-instruction generator comprises a sequencer for generating instruc-tion addresses, a memory for generating instructions in response to the addresses and a pipeline register adapted to receive the instructions for execution.  The sequencer operates at a constant CLK 1 rate while the pipeline register operates at a variable CLK 2 rate; i.e., the occurrence of a branch instruction in the pipeline register operates to inhibit CLK 2 for one CLK 1 time so as to prevent loading for execution of the aborted sequential instruction during the loading of a new non-sequential instruction address.  CLK 2 resumes upon the next CLK 1 signal to resume sequential opera-tion.  Special branch instructions are utilized to fetch macro-instructions from a pipelined system of macro-instruction registers.  A two-tier synchronous arbitra-tion system for memory requests is also disclosed.

Abstract: A B S T R A C T           The invention relates to a method for the preparation of cyclohexanol and/or cyclohexanone by hydrogenating benzene to cyclohexene, hydrating the cyclohexene to cyclohexanol and/or oxidating it to cyclohexanone, recovering the cyclohexanol and/or cyclohexanone, and returning unconverted benzene and/or cyclohexene to the hydrogenating stop. The method according to the invention is characterized in that the mixture of cyclohexane with benzene and/or cyclohexene, which has also been obtained during the separation of cyclohexanol from the reaction mixture of the hydration step and/or cyclohexanone from the reaction mixture of the oxidation step, is subjected to a dehydrogenation reaction, and the benzene thus obtained is returned to the hydrogenation step.          The method according to the invention has the great advantage that the difficult separation of cyclohexane from mixtures with benzene and/or cyclohexene can be dispensed with .  Losses of expensive extractive distillation agent are avoided.  Neither is any cyclohexane left as by-product for wich a use will have to be found.  In the hydrogenation step a higher degree of benzene conversion can be applied, so that economic process operation has become possible.

Abstract: ABSTRACT:             A method of providing in a self-registering man-ner underpasses in a semiconductor device having insulated gate field effect transistor, in which the underpasses below the field oxide connect together electrode zones of the field effect transistors. The field oxide is obtained by local oxidation by means of an oxidation mask.  After a first oxidation treatment a part of the oxidation mask is removed and the semiconductor body is doped locally with As or Sb atoms for the underpasses.  The apertures in the doping mark coincides substantially with the part of the oxidation mask to be removed, without critical alignment being necessary therefor, in that the masking effect of the already obtained oxide is used. After the doping treatment a second oxidation treatment is carried out to complete the field oxide.

Abstract: ABSTRACT The invention relates to a hydraulically actuated feed roll lift mechanism for feeds utilized to feed strip stock into a machine, such as a mechanical press. Regulated hydraulic pressure acting against a piston that is connected to one of the feed rolls through a yoke forces the feed roll against the stock to grip the stock and cause an increment thereof to be fed into the press when the rolls are rotated.  A roll opening cam, which is connected to the press crankshaft, advances a small piston to displace oil against the other side of the piston while the stock is at rest to thereby separate the rolls during the time that the dies are in contact with the stock in the press. The time at which roll separation is initiated is control-led by adjusting the angular position of the cam on its shaft, as by releasing a frictional lock mechanism, rotating the cam to the desired position, and then again locking it in place.  The invention is particularly related to a double feed roll system wherein opposing feed rolls are located at the indeed and outfeed sides of the press so that the stock is both pushed and pulled therethrough.  Identical cam roll lift mechanisms are utilized for both of the pairs of feed rolls wherein the cams are mounted on the same shaft and can be adjusted independently of each other. This enables the in-feed and outfeed rolls to be separated at different times during the cycle of the press.

The operator means comprises first and second permanent magnets for generating separate magnetic fields of the same polarity proximate the magnetizable deflection end of the actuator element and magnetic core means combined with the permanent magnets to form at least first and second magnetic holding circuits with the deflection end of the actuator element through a common return path.  A winding on the return path of the core means when energized generates flux in opposition to the flux from the permanent magnets to release the actuator element for movement to an operative position.
