Filed: 1978-07-17
Granted: 1985-11-11
Abstract: 1. A process for the isolation and working up of undesired by-products consisting of aromatic aldehydes and nitrous gases, which are obtained during the nitration in excess nitric acid of optionally substituted aromatic compounds containing aliphatic side-chains by partial oxidation of the side-chains, characterized in that at the same time as the rectification of the nitro-aromatic compound, the optionally substituted aromatic aldehyde is distilled off over the head of the column as an azeotrope with water by maintaining an aqueous phase within the rectification column in addition to the organic phase, and after oxidation to the corresponding carboxylic acid is discharged and the nitrous gases contained in the off-gas are reconverted into nitric acid in an adsorption column in an aqueous phase obtained in the nitration process, which can optionally contain nitric acid, in counter-current in the presence of oxygen.

Abstract: The functions of two virtual operating systems (e.g. S/370 VM, VSE or IX370 and S/88 OS) are merged into one physical system. Partner pairs of S/88 processors run the S/88 OS and handle the fault tolerant and single system image aspects of the system. One or more partner pairs of S/370 processors are coupled to corresponding S/88 processors directly and through the S/88 bus. Each S/370 processor is allocated form 1 to 16 megabytes of contiguous storage from the S/88 main storage. Each S/370 virtual operating system thinks its memory allocation starts at address 0, and it manages its memory through normal S/370 dynamic memory allocation and paging techniques. The S/370 is limit checked to prevent the S/370 from accessing S/88 memory space. The S/88 Operating System is the master over all system hardware and I/O devices. The S/88 processors across the S/370 address space in direct response to a S/88 application program so that the S/88 may move I/O data into the S/370 I/O buffers and process the S/370 I/O operations. The S/88 and S/370 peer processor pairs to execute their respective Operating Systems in a single system environment without significant rewriting of either operating system. Neither operating system is aware of the other operating system nor the other processor pairs.

Step (d) is carried out by treating the membrane with a quaternizing agent dissolved in a solvent capable of penetrating the membrane. This reaction is preferably carried out in two stages, the second at a higher temperature than the first, and may also involve treatment first with a polyfunetional quaternizing agent and then with a monofunctional one. In examples membranes derived from 2- or 4-vinylpyridine and vinylidene chloride or chloroacrylonitrile are quaternized with diiodoethane and/or methyl iodide.

Abstract: Adenosine analogues of formule (I) which act selectively at adenosine receptors and which act in general as adenosine antagonists are disclosed. From in vitro studies it is known that specific physiological effects can be distinguished as a result of this selectivity and that adenosine receptor activity in vitro correlates with adenosine receptor activity in vivo. Pharmaceutical preparations of the subject compounds can be prepared on the basis of the selective binding activity of the compounds disclosed herein which can be expected to enhance certain physiological effects while minimizing others, such as decreasing blood pressure without decreasing heart rate.
