Abstract: ABSTRACT: "Recording and/or reproducing apparatus."     In a recording and/or reproducing apparatus com-prising at least one magnetic head (29, 30), which is ro-tatable in a given direction of rotation (31), and at least one tape guide (16) for a magnetic tape (3), which guide is arranged near said head, said tape passes round at least a part of the circumferential surface of the tape guide and past the magnetic head, which rotates at a given level oblique tracks being scanned by means of said magnetic head in a given direction of movement (36) of the magnetic tape, which tracks are each time situated within a longitudinal half of the magnetic tape. In this apparatus means are provided whereby the magnetic tape can also be driven in a direction of movement (37) opposite to the given direction of movement, and by means of a mag-netic head (39, 40) which rotates in a direction of rotation (38) opposite to the given direction of rotation and at a further level which is spaced from the given level by a distance substantially equal to half the width of the mag-netic tape, tracks are scanned which are situated within the second longitudinal half of the magnetic tape (Fig. 1).

Abstract: GALVANIC PRIMARY ELEMENT                 ABSTRACT OF THE DISCLOSURE     A galvanic primary element of the system Li/H2O2 comprises a gas diffusion electrode which separates the lithium electrode from the cathode space which is filled with aqeuous H2O2 solution.          In the working layer which is flanked by capillary active cover layers of the gas diffusion electrode, automatically drawn-in H2O2 is decomposed into H2O2  and O2 catalytically until the gas pressure is in equilibrium with capillary forces and thereby interrupts the access of additional H2O2 solution to the working layer.  Short circuiting of the cell or connection of a load causes a reduction of the gas pressure due to electrochemical reaction of the O2 with the lithium so that fresh reactant solution can flow in.   A reaction regime matching the current draw becomes possible because of the property or polyurethane to gel in aqueous H2O2 by virtue of the fact that the H2O2  is slowly pressed out of the gel as out of a sponge by means of a ram toward the gas diffusion electrode.

Abstract: HEART VALVE PROSTHESIS     ABSTRACT OF THE DISCLOSURE         Single or double-leaflet heart valves having improved flow through the orifice defined by an annular valve body include a pair of leaflets which may be arcuate or flat in cross section.  Guides protrude oppositely from the leaflets and are received in complementary depressions in the interior wall surface preferably of a pair of standards which extend downstream from the annular valve body at generally diametrically opposite locations.  The depressions are preferably elongated so that, as the leaflets pivot between the open and closed positions, the guides move from one end of the elongated depressions to the other. Eccentric pivot axes provide for quick response of the leaflets, and the location of the depressions in the standards moves the leaflets out of the annular valve body, reducing resistance to the free flow of blood therethrough.  The leaflet valve members are preferably arcuate in cross section and may be essentially a portion of the wall of a circular tube.

Abstract: ABSTRACT OF THE DISCLOSURE           A rock picker of the floating rotating reel type has the following features:  (1)  An intermediate pinion is provided for the drive of the reel at the pivot point for the reel assembly.  This enables the reel to pivot to clear obstacles without per se changing the relative driving relationships; centre-to-centre distances can remain constant regardless of the pivoting of the reel.  (2)  Loosely-attached grille teeth permit rocks to wiggle out from between grille teeth.  Each grille tooth is provided with a receptacle and shoulder which bears against an angle-iron transversely located on the frame.          Clearance between the receptacle and the angle iron permits wiggling of the teeth to occur.  A bolt passing through a spacer flange attached to each tooth prevents the tooth from sliding off the angle iron.  (3)  The draw bar is vertically pivotally attached to the transverse frame member, and the angle of the frame member to the draw bar is adjustable to permit the rock picker to swing relative to the tractor or other vehicle pulling it.  (4)  The paddles, generally radially mounted on the reel, are interconnected by coil springs under tension which permit some paddle deflection when large rocks or other obstacles are encountered but which also tend to maintain the paddles in preferred radial orientation.  (5)  The canopy over the reel, which offers protection to the driver of the tractor from flying stones or the like, is also used to support the reel mounting -no separate mounting arm is needed.  (6)  The entire grille assembly is capable of pivotal movement about a transverse axis to adjust to surface level variations, and the reel is transversely pivotally mounted on the grille supporting frame, thus permitting double pivotal movement for good response to ground surface obstacles.

A particular use of the agglomerated rubbery polymer latexes is in the production of ABS resins.

Abstract: ABSTRACT OF THE DISCLOSURE      A continuous casting installation has a dummy bar which is designed such that its connection with a strand can be broken by moving the dummy bar and the strand relative to one another in a direction transverse to the longitudinal axis of the strand.  A straightening roll for the strand is movable in this direction between a raised position and a lowered position.  A support roll is mounted in the region of the straightening roll and is pivot-able between an upright position and an inclined position clear of the casting path.  In operation, the connection between the dummy bar and the strand is positioned between the straightening roll and the support roll.  The straightening roll is in its raised position and is located above the strand while the support roll is in its upright position and supports the dummy bar.  The straightening roll is now lowered to straighten the strand thereby simultaneously breaking the connection between the dummy bar and the strand.  The straightened strand continues travelling along the casting path and the leading end of the strand moves into the support roll and pivots the latter to its inclined position.  The proximity of the straightening roll and the support roll results in the exertion of only a small moment on the dummy bar during disconnection from the strand.  The ability of the support roll to be pivoted to a position clear of the casting path virtually eliminates any danger of this roll stopping the strand and inter-rupting the casting operation.

Abstract: MONOCLONAL ANTIBODIES SPECIFIC FOR THE HUMAN TRANSFERRIN RECEPTOR GLYCOPROTEIN                         ABSTRACT Monoclonal antibodies are produced specific for the cell surface transferrin receptor of human cells. Animals are inoculated with purified human transferrin receptor glycoprotein, human hematopoietic cells or fragments thereof, and spleen cells obtained from the animals are fused with myeloma cells to produce hybridomas.  The hybridomas are cultured as clones, and antibodies obtained from the individual clones are tested for their specificty for human transferrin receptor.  Clones which produce antibodies specific for the receptor and that interfere with or block transferrin binding are selected for further culturing to produce the antibody, and the antibody is obtained from the culture growth medium or from ascitic fluid of an animal bearing a tumor of the hybridoma.  Monoclonal antibodies which block transferrin binding are useful in regulating cell growth and for other therapeutic uses.
