Abstract: ABSTRACT OF THE DISCLOSURE           Phenol ethers such as 1-[4-[2-(cyclopropylmethoxy)-ethyl]phenoxy]-3-((1-methylethyl)amino]-2-propanol, otherwise known as betaxolol, of formula:       are prepared from p-hydroxyphenethyl alcohol by first reacting at the phenolic group, with epichlorohydrin followed by isopropylamine, to prepare the required secondary amine-hydroxy side chain.  Protection of the alcoholic group is not required during these steps.  Then the secondary amine-alcohol group is protected by reaction with a suitable aldehyde such as benzaldehyde to form an oxazolidine ring protectant whilst the alcohol chain is elaborated.  The oxazolidine ring protectant is removed by simple acid hydrolysis.  The phenol ether products have pharmaceutical utility, e.g. as B-adrenergic blocking agents.

Abstract: ABSTRACT A heat exchanger  (38)   is provided which may be used in a mass transfer device (20), such as an oxygen-ator or a dialyzer. The heat exchanger comprises a core (40) formed of a corrugated metal having a high thermal conductivity. Each of the corrugations of the core com-prises substantially parallel side walls (70, 72).   A first fluid, such as blood, is introduced onto the out-side of the core.   A second fluid, such as water,  is introduced into the inside of the core.  The first and second  fluids will  be in heat  exchange relationship with each other and the flow of the fluids is substan-tially uniform resulting from the substantially paral-lel side walls of the corrugations.     The core is formed by providing a flexible metal hose,  annealing the flexible metal hose,  compressing the annealed hose and expanding the compressed hose to a length that is substantially less than its original length but greater than its length during compression.

Abstract: ABSTRACT:           In the method a number of slices of semiconduc-tor material are heated in a reactor tube arranged inside a furnace tube and having a tube wall which is provided with openings, through which a reaction gas is passed for depositing a semiconductor material.  This is effected by producing in the furnace tube a flow of the reaction gas along the outer side of the wall of the reactor tube and by passing only a part of this flow through the openings into the reactor tube.  By the use of this method, it is prevented that particles of different size and composition-which may be formed in the reaction gas - are deposited on the slices.

Abstract: TITLE:  METHOD AND APPARATUS FOR PROTECTING         COMPUTER SOFTWARE UTILIZING AN ACTIVE CODED HARDWARE DEVICE         INVENTORS:  WAYNE W. CHOU and RICHARD E. ERETT     ABSTRACT            A method and apparatus are provided for protecting computer software using an active coded hardware apparatus which is adapted to be connected by an interface connector to a communications port of a computer.  The computer is directed by a coded software program in which a small section of the code of the computer software interrogates the com-munications port periodically to determine if the active coded hardware device is present and connected.  The active coded hardware device has a permanently established preset code on an active presettable counter circuit which code is transmitted when interrogated.  If the active coded hardware device is present when interrogated and the correct code re-turned though the communications port of the computer, the program is permitted to continue insuring that the software is properly protected at all times.  The active coded hardware device with its particular code and circuitry are sealed in epoxy as a deterrent against tampering.  In order to violate the hardware it would be necessary to construct a duplicate of the hardware device in order to run a second copy of the software. Since the device is active containing electrical logical elements the degree in duplicating the device and its function without the benefit of circuit diagrams will be greater than the software itself.  The particular hardware may be used alone or will permit daisy-chaining allowing 2, 3 or even an entire family of other elements with their own individual codes to operate simultaneously and at the same time permit computer peripherals to remain connected to the same port.  A variety of time and logic elements may be added to the basic configuration in order to increase the difficulty of duplicating or violating the system.

Abstract: ABSTRACT OF THE DISCLOSURE     Simple and inexpensive hollow reactors in the form of spirals of corrugated plastic tubes, which are coiled in  the  same  direction  and  clamped  in  large  numbers adjacent to each other in a drum-like cage for use in biological waste water  purification.   This  drum-like cage  is  mounted  so  that  it  can  rotate  in  a waste-water-filled tank,  in such a way that only the outer  spiral  turns  project  above  the  water  level.          During rotation in the opposite direction, each emerging tube  end  admits  air,  which  on  further  rotation  is trapped as a bubble in the spiral and is transported because of its inertia to the underwater spiral end.  In this process the liquid contained in front of it in the tube is displaced and an equal volume is admitted at the inlet opening from the surrounding waste water.  The air emerging from the inner spiral end rises upwards in individual bubbles between the spiral reactors.  While part of the emerging waste water is entrained by the suction effect of the bubbles, the other part can flow away out of the laterally open inside space.

Abstract: Abstract of the Disclosure In a device for casting lead grids for electric battery pla-tes, a highly porous ceramic mold lining, preferably of zirconium oxide, is prepared by flame-spraying.  Such a lining can include a thin surface coating on a profiled, basic metallic mold or a separately prepared insert plate which is retained to a metallic mold holder.  The ceramic surface coating may be accurately formed in place, or may be formed as an over-spray which is then reduced in thickness.    Formation of the surface coating may be accomplished by placing masks on the basic metallic mold during the flame-spraying, for those areas of the grid which tend to accumulate material, or by adjusting an initially coarse profile of the ceramic layer to the exact profile of the casting by a material-removing treatment.  Alternatively, the insert plate may be manu-factured on a matrix with a surface contour which corresponds to the half-profile of the lead grid, as a positive mold to which the ceramic material is applied by flame-spraying after an inter-mediate coating with a removable adhesive layer.  The resulting ceramic coating is then subjected to surface grinding, and is removed from the matrix.

Abstract: ABSTRACT OF THE DISCLOSURE         A method for installing a pipeline for transporting a warm fluid, such as newly-produced oil, across arctic seafloor underlain by a permafrost zone without danger of rupture of the pipeline caused by thawing in the supporting permafrost zone comprises (1) drilling a series of boreholes along the seafloor through a thawed zone of subsea soil so as to penetrate a distance into a zone of permafrost lying thereunder, (2) circulating a warm fluid through each borehole so as to cause a zone of prethawing in the permafrost zone and thereby create a slump trough on the surface of the seafloor along a path marked by the series of boreholes; and (3) installing a warm fluid bearing pipeline along the bottom of the slump trough.  Usually a temperature differential between the warm fluid and the bottom of the borehole of at least 2 degrees Fahrenheit is required to assure economical prethawing of the permafrost zone.
