Abstract: SEISMIC TRANSDUCER BASEPLATE      AND USING ASSEMBLY                    Abstract A lightweight rigid housing and baseplate structure for a seismic transducer.  The baseplate (12) includes a central hub (26) for receiving a lower piston rod (76). Upper and lower skin plates (32 and 36) extend radially outward from the central hub (26).  A plurality of equally angularly spaced reinforcing plates (40) also extend ra-dially outward from the hub (26) and have their upper and lower edges rigidly connected to the upper and lower skin plates.  A housing assembly (78) rigidly connects an upper piston rod (74) to the baseplate (12), and includes a frusto-conical section (82).  The lightweight rigid housing (78) and baseplate (12) structure provides a seismic trans-ducer having in-phase force distribution over substantially the entire area of the baseplate as it is engaged with the earth.

Abstract: "SYNTHESIS OF 2-AMINO-2-DEOXYGLYCOSES AND  2-AMINO-2-DEOXYGLYCOSIDES FROM GLYCALS"                        ABSTRACT OF THE DISCLOSURE 0-acylated-2-azido-2-deoxy glycosyl nitrates are used to prepare 0-acylated-2-azido-2-deoxy glycosyl halides.  The halides are useful in the preparation of 0-acetylated-2-azido-2-deoxy glycosides, which in turn can be reduced to 2-amino-2-deoxy glycosides.  Of particular interest are the syntheses of 2-amino-2-deoxy glycosides which correspond to the terminal units of the antigenic determinant for the human A blood group.  Attachment of these glycosides to a solid support provides immunoabsorbents which effectively and preferentially absorb anti-A-antibodies from blood plasma.

Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed is a stepping motor control utilizing a microprocessor.  The control is suitable for driving one or more stepping motors one at a time or in unison.  In the illustrated embodiment when plural motors are driven together they are driven at the same rate although several of the fea-tures of the invention are suitable for use in circuits pro-viding contouring control;  i.e., where separate motors are driven at separate stepping rates proportional to the relative distances each is to traverse for a single movement.  An acceleration/deceleration circuit is utilized which provides simple yet highly accurate and efficient control of the step-ping motors.  Feed rate compensation fox simultaneous drive of two motors is provided. Also a circuit is provided to allow stepping rates in excess of the counting rate capability of the microprocessor.

Abstract: ABSTRACT OF THE DISCLOSURE     An electronic depth finder apparatus is shown for use in fishing and/or navigation, and it includes a combined impulse control means and read-out, as well as a remote cooperating transducer immersed in the water.  The inven-tion relates to a means of adjustably mounting the trans-ducer on a boat so that the transducer may be capable of as many as three planes of movement; namely, swinging movement in a vertical plane, unlimited rotational movement in a horizontal plane about a vertical axis, and up and down vertical movement between a lower "searching" position and an upper "running" position.  The upper "running" position allows operation of the apparatus when the boat is moving at high speeds.

Abstract: TITLE OF THE INVENTION         PRETREATMENT PROCESS FOR GALVANIZED METAL PRIOR TO ITS COATING WITH ORGANIC POWDER            ABSTRACT OF THE INVENTION         This invention relates to a pretreatment process for galvanized metal which, unlike existing processes, was specifically developed for galvanized metal.  Because of the natural corrosion protection properties of the zinc cladding of galvanized metal, no additional passivation is necessary as is required with existing processes.  Also, the invention relates to the galvanized metal which has been pretreated by the process of this invention prior to application of an organic powder coating.  Galvanized metal treated by this pretreatment process prior to coating leads to a uniform coating which is impervious to acid, base and salt solutions, and which will not scratch or flake off on impact.

Abstract: ABSTRACT OF THE DISCLOSURE      A power metal-forming press of the underdrive type having a pair of laterally spaced rocker shafts journaled in the base.  A set of vertical pull rods are connected to arms at the ends of the shafts for reciprocating the press slide.  Driving subassemblies are provided at the near side and far side of the press each including a main drive gear carrying an eccentric.  A pitman pivotally engaging the eccentric has a short arm which is coupled via a connecting link to a rocker arm on one of the shafts. The pitman also has a long arm extending generally in the opposite direction, the end of the long arm being guided with respect to the frame along a generally longitudinal path.  The long arm is so angled with respect to the connecting link under conditions of bottoming of the slide that upon rotation of the main drive gear the short arm traces a generally elliptical path having a major axis which bears an acute angle to the bottoming orientation of the connecting link.  As a result the slide moves relatively slower as it approaches its bottoming position and relatively faster as it leaves its bottoming position.

Abstract: ABSTRACT OF THE DISCLOSURE            A swimming pool wall, for placement in an excavation, is made up of a series of bendable plates having only vertical flanges for stiffening while permitting shaping the wall to a selected outline.  A resilient coping strip embranes the upper edge of the wall and houses a rigid metal bar to retain the upper edge of the wall in the desired configuration while other braces, at the lower edge of the wall extend from the plates to the outer edge portions of the flanges to securely maintain the lower edge of the wall in the desired configuration.  Vertical Z-shaped bars are secured to certain of the plates to further stiffen them and further braces, secured to the flanges, ex-tend diagonally upward into a concrete apron, selected ones of the diagonal braces carrying a form plate for defining the outer edge of the apron.  Rigid bars are used to hold corner plates to a desired curvature during assembly of the pool wall and its placement in the excavation.  After back-filling and forming the apron, those bars are removed.

Abstract: A process of pneumatic stirring of a bath of molten metal according to which a stirring fluid is injected through permeable refractory elements arranged at the bottom of a crucible containing the bath, in which the used stirring fluid is, at least temporarily, an organic liquid such as hydrocarbon. The process is advantageously used on a bath of molten pig iron during refining of the same by oxygen, and in which the organic liquid is replaced immediately after decarburization of the bath by an inert gas such as argon or nitrogen. The process thus permits an efficient stirring of the bath of molten metal without the risk of polluting the metal either by hydrogen or nitrogen.
