Abstract: Boring Tool with Coarse and Fine Adjustment t Abstract A boring tool includes a central shaft which carries a tool head on a shaft working end and which is mounted in a rotatable bushing for eccentric movement in the tool body.          For work adjustment up to 1.00 inch on diameter, the tool head is radially slidable on the working end of the central shaft by an adjustment screw arrangement while the shaft is held by the bushing. For micro-adjustment, the bushing is rotated to move the shaft working end in an eccentric path with a key on the tool body translating this movement into radial micro-adjustment of the tool head to .0001 inch.

Abstract: ABSTRACT           Monoclonal antibodies specific to CEA A process for producing monoclonal antibodies specific to carcinoembryonic antigen (CEA), comprising immunizing a mammal with a first CEA to produce cells capable of producing antibodies, collecting the cells from the mammal, fusing the collected cells with the cells of a line of a myeloma of another mammal, selecting the thus-obtained hybridoma cells on the basis of their capacity to produce antibodies reactive with said first CEA, subjecting the thus-selected hybridoma cells to cloning, selecting the thus-obtained monoclones on the basis of the reactivities of monoclonal antibodies produced by them with at least one antigen selected from CEAs other than said first CEA and CEA-related antigens of normal adult human origin, culturing the thus-obtained monoclones and recovering the desired monoclonal antibodies from the spent culture.  The selection may preferably be effected by radioimmunoassay using a marker antigen labelled with a radioactive substance.  Monoclonal anti-CEA antibodies thus-produced have specific reactivity with the antigenic determinants of CEA molecules and thus may with advantage be used for various clinical applications and fundamental medical studies such as, for example, for determination of the concentration of CEA and CEA-related antigens.

Abstract: ABSTRACT OF THE DISCLOSURE:         An aggregate and/or integrate comprising of silver and tin oxides and/or tin alloy oxides of 4 - 25 weight % which have been prepared to have the oxides dis-persed in the silver, are subjected to a temperature above the melting point of silver, whereby an electrical contact material made from said aggregate and/or integrate comes to have a continuous silver matrix as if produced by an inter-nal oxidation method and also to have such uniform disper-sion of the metal oxides in said silver matrix which is comparable or superior to that producible by a powder mettallurgical method.  The above-mentioned heat treatment is accompanied with hammer or press forging resulting in dimensional reduction of the aggregate and/or integrate such as their shaping, upsetting, and drawing-down.  The contact material has, in addition to an excellent elongation and high conductivity, much greater resistance to shock.

Abstract: L'invention concerne un procédé de préparation continue d'hypochlorite de sodium à haute concentration consistant à faire réagir en deux stades du chlore pur ou dilué par des gaz inertes avec une solution d'hydroxyde de sodium ayant une concentration comprise entre 20 et 50 % en poids, dans lequel le premier stade de la chloration de la solution d'hydroxyde de sodium est effectué dans une colonne d'absorption dans laquelle les concentrations en NaClO et NaOH dans la solution d'hypochlorite de sodium sont limitées à respectivement 15 % et 4,5 % en poids et dans lequel le deuxième stade de la chloration de la solution d'hypochlorite de sodium sortant de la colonne d'absorption est effectué avec du chlore pur ou dilué par des gaz inertes dans un cristallisoir adapté convenablement agité. Ce procédé de l'invention permet d'atténuer fortement les risques d'encrassement de l'échangeur de chaleur placé extérieurement sur le circuit de recirculation d'eaux-mères du cristallisoir. En outre, ce procédé de l'invention conduit à l'obtention d'un chlorure de sodium de granulométrie d'au moins 400 microns, ce qui facilite l'opération de filtration et diminue la rétention d'eaux-mères dans le sel.

Abstract: A method and apparatus for applying a coating to a conductor in a single pass, to produce magnet wire with a coating having favourable concentricity and continuity characteristics. The apparatus includes an entrance die, an exit die and a die block therebetween, The entrance and exit dies include a throat portion and an entrance opening larger than the throat portion. The die block has an interior passage forming a die chamber which is filled with flowable hardenable material under pressure, from a reservoir. Pay-out and take-up devices are adapted to feed wire through said entrance die, said die passage and hence through said exit die. Upon the wire entering the die apparatus the converging interior wall provides a surface adjacent to which the material creates a support of coating material such that the wire does not contact the die and the wire is centered in the die throats and forms a continuous and concentric layer of coating on the wire.

Abstract: Abstract of the Disclosure undesired intentional interference, i.e. jamming signals in a multiple accessing mobile subscriber system employing a plurality of subscriber communication terminals, selectively transmitting and receiving desired signals from one another via a central node or repeater station, is achieved by intercepting relatively strong jamming signals, also directly received by the various subscriber communication terminals, and transmitting the jamming signals to the central node where they are then retransmitted or relayed to the sub-scriber  terminals in a dedicated orthogonal multiplexed channel. relative to respective signal channels carrying desired communi-cations signals. Each terminal includes means for demultiplexing the orthogonal channel and the signal channel.  The relayed jamming signals are adjusted in amplitude and time position so that they are equal to and coincident in time with the directly received jamming signals,  The two jamming signals are then fed to signal differencing means which operates to cancel the jamming signals while providing an interference free output of the de-sired signal.

The molecular weight distri-butions of polymers formed in the presence of the catalyst compositions are narrowed as the chain length of R is increased.

The inner tube is coupled through a swivel assembly to a cartridge cap.  The cartridge cap is threadedly coupled to the coring tool, and in particular to the  outer  tube.    Thus,  the  cartridge  cap  is  arranged  and configured to be rotated, and thus longitudinally adjusted with respect to the outer tube.  An upper portion of the cartridge cap is provided with a plurality of radially expanding fingers.   A jam nut is disposed within a cylindrical array formed by the fingers, and is threadably engaged with the inside surface of the fingers.  The jam nut has a frustoconical shape, and thus as the jam nut is advanced longitudinally with respect to the fingers, the  fingers  are  urged  outwardly,  ultimately  in  a  tight  and locking contact with an interior surface of the coring tool.  A hollow cylindrical wrench is disposed through the end of the core barrel to engage the cartridge cap and rotate it to the desired longitudinal position.  A jam nut wrench is disposed through the hollow cartridge cap wrench, and when the inner tube has been appropriately adjusted is used to advance the jam nut downwardly in  the  fingers  to  expand  the  fingers  and  thus  lock  the longitudinal position of the cartridge cap.
