Abstract: The present invention relates to the preparation of aminoalkyl p-hydroxyphenyl ketones. Certain of these ketones are well known as important intermediates in the production of compounds having pharmaceutical activity, for example octopamine or synephrine. The known Houben-Hoesch reaction is a variation of the Friedel-Crafts reaction and involves the condensation of a phenolic substrate with a nitrile in the presence of a Lewis acid catalyst to give a hydroxy-aryl ketone. It is an object of the invention to provide a new or improved process for the manufacture of aminoalkyl p-hydroxyphenyl ketones. According to the invention, there is provided a process for the preparation of an aminoalkyl p-hydroxyphenyl ketone comprising reacting phenol with a nitrile, in the presence of a Lewis acid catalyst, to cause condensation thereof, the process being characterised in that the reaction is carried out in a medium comprising a nitroalkane solvent for the reactants. A preferred but non-limiting feature of the invention is the productiqn of 2'amino-4-hydroxyacetophenones. The present invention is based on the surprising discovery that nitroalkanes are unexpectedly much better solvents for this reaction, being less toxic, giving a better yield and also ensuring a homogeneous reaction medium. The nitroalkanes may also be diluted with a halogenated hydrocarbon solvent, which acts as an inert diluent, thus reducing the amount of nitroalkane used, and making the reaction less hazardous.

Abstract: A mechanical seal assembly is disclosed in which the seal faces of the primary seal members remain essentially perpendicular to the shaft of the equipment being sealed regardless of any misalignment between the shaft and the equipment. The seal assembly has a sleeve (20) for mounting on the shaft (12), the sleeve providing a support structure wherein all primary seal member faces (46, 46 min ) are aligned with respect to this support structure regardless of loading. The primary seals are uniformly and persistently urged toward the support structure, without sliding parts, by the combination of net hydraulic pressure at the mated seal faces plus steady bias from a minimally flexing biasing source, such as compression springs, at one end of the sleeve. In a double balanced double seal embodiment, a piston area (A, B) is defined on the rear of each primary seal member. Each primary seal piston area and the seal face contact area of the associated mated primary seals is determined without regard to location or thickness of secondary seals. Each piston area is a predetermined fixed area equal to a major portion of the associated primary seal face contact area. <IMAGE>

Abstract: A fault tolerant computer system includes at least two central processing units each having a cache memory and a parity error detector adapted to sense parity errors in blocks of information read from and write to cache and to issue a cache parity read or write error flag if a parity error is sensed. A system bus couples the CPU to a System Control Unit having a parity error correction facility, and a memory bus couples the SCU to a main memory. An error recovery control feature distributed across the CPU, a Service Processor and the operating system software is responsive to the sensing of a read parity error flag in a sending CPU and a write parity error flag in a receiving CPU in conjunction with a siphon operation for transferring the faulting block from the sending CPU to main memory via the SCU (in which given faulting block is corrected) and for subsequently transferring the corrected memory block from main memory to the receiving CPU when a retry is instituted. <IMAGE>

Abstract: A method for refining triglyceride oils, preferably of natural origin. The method is particularly suitable for the refining of oils meant for direct consumption such as are sunflower oil, palm oil and olive oil. The method consists of a two-step treatment comprising a heating treatment and a subsequent stripping treatment. The stripping temperature is at 30-200  DEG C and the heating treatment consists of keeping the oil at an elevated but moderate temperature (30-180  DEG C). A stable oil results, which may be characterized further either by a specific flavour profile which may be appraised as natural and attractive or by the absence of any flavour.

Abstract: A portable ground water sampling apparatus has a submersible pump or other water sampling apparatus attached through a hose to a hydraulically driven spool mounted on a boom attached to the bed of a truck or trailer. The hydraulically operated boom enables the operator to place the pump over the well and lower the pump into the well from the spool. A second spool also mounted on the boom operates a cable attached to a discrete liquid sampler or appliance of operator's choice for lowering into the well to take water samples or collect data. A decontamination apparatus is also attached to the boom and washes the hose and cable to remove contaminants therefrom. The contaminated wash fluid is removed to a holding tank for later disposal at a safe site. Hydraulically driven level-wind mechanisms are attached to each spool.

Abstract: This invention relates to delivery of biologically active cargo molecules such as polypeptides and nucleic acids into the cytoplasm and nuclei of cells  in vitro  and  in vivo.  Intracellular delivery of cargo molecules according to this invention is accomplished by the use of novel transport polypeptides which comprise one or more portions of HIV tat protein and which are covalently attached to cargo molecules. The transport polypeptides of this invention are characterized by the presence of the tat basic region (amino acids 49-57), the absence of the tat cysteine-rich region (amino acids 22-36) and the absence of the tat exon 2-encoded carboxy-terminal domain (amino acids 73-86) of the naturally-occurring tat protein. By virtue of the absence of the cysteine-rich region found in conventional tat proteins, transport polypeptides of this invention solve the problems of spurious trans-activation and disulfide aggregation. The reduced size of the transport polypeptides of this invention also minimizes interference with the biological activity of the cargo molecule.

Abstract: A truck platform is elevated at one end and then moved rearwardly by pulsation cylinders which slowly accelerate and then rapidly decelerate the platform and truck. The abrupt deceleration causes the material in the truck to continue to move rearwardly separating from the truck floor and move out of the truck in a stair step fashion through repeating pulsations. The angle in which the platform needs to be raised is minimized by the application of pulsation forces to the system thereby improving the safety and ease of unloading the truck.
