Abstract: ABSTRACT                 JET PRINTING APPARATUS AND METHOD A jet printing apparatus is shown having a reservoir (13) for storing printing medium.  A perforate member (37) having at least one surface (39) which is exposed to the printing medium in the reservoir with the ink entering the perforations (41).  A drive motor (29) effects relative movement of the perforate member (37) past a printing station (45) having a fluid jet (47) with a plurality of nozzles (49).  Electrically controlled valves (53) selectively supply air to the nozzles (49) to eject printing medium from the perforate member (37) onto a printing substrate.  In one embodiment, the perforate member (37) is a cylindrical mask having spaced columns of perforations (41) which are successively aligned with the fluid jet nozzles (49) at the printing station (45).  In another embodiment, a mesh belt (71) having perforations (73) is moved between the fluid jet nozzles (91) and an orifice plate (103) which has orifices (105) aligned with the nozzles (91) of the fluid jet (87).  Air from selected nozzles (91) ejects ink from the perforations (73) through an aligned orifice (105) opening onto the printing substrate.

Abstract: ABSTRACT OF THE DISCLOSURE       The rod-breaking device comprises a deflecting guide (10) movable alternately across the normal straight path of a cigarette rod (B) issuing from a rod-forming mechanism and entering the inlet (8) of a rod-processing unit (9). The movement of the deflecting guide into active position serves to break the rod by cooperating with a fixed abutment (14), whereafter the deflecting guide stops in said active position to deflect the following rod out of the normal path. The movement of the deflecting guide into the opposite inactive position serves to break the rod and to bring the said deflecting guide to an inactive position out of the normal path of the rod. A transverse blade (15) is secured on the deflecting guide (10) in such a manner as to move, across the normal path of the cigarette rod, close to the inlet (8) of the processing unit. Upon stopping of the cigarette-making machine the deflecting guide and blade are moved into active position, thus leading to the elimination of a segment of rod delimited downstream by the clean cut effected by the blade (15) and upstream by the break effected by the cooperation of the deflecting guide (10) with the fixed abutment (14) (Figure 3).

Abstract: ABSTRACT Monoclonal antibodies are produced for a family of glycoproteins which are selectively expressed on the surface of nucleated human hemotopoietic cells but which are absent from other normal human cells.  Mice are inoculated with human hematopoietic cells or fragments thereof, and spleen cells obtained from the mice are fused with mice myeloma cells to produce hybridomas. The hybridomas are cultured as clones, and antibodies obtained from the individual clones are tested for their specificity for hematopoietic cells.  Clones which produce antibodies specific for surface glycoproteins of nucleated human hematopoietic cells are selected for further culturing to produce the antibody, and the antibody is obtained from the culture growth medium or from ascitic fluid of mice bearing the hybridoma tumor.

Abstract: METHODS AND APPARATUS FOR HEATING METAL PARTS WITH MAGNETICALLY DRIVEN TRAVELLING ELECTRIC ARC            ABSTRACT OF THE DISCLOSURE:  Methods and apparatus for the welding and heat treating of metal parts in which an electric arc extends between a pair of adjacent metal parts or between an electrode and one or more metal parts with the arc tra-versing the metal part or parts a plurality of times during the heating cycle.  For finite length metal parts, i.e. when-the surface or surfaces to be heated do not provide closed paths to be followed by the arc, the arc is initiated, caused to follow the surface, extinguished and then reinitiated, ox is caused to traverse the surfaces in alternately opposite directions after initiation.  With finite length metal parts, run-off tabs are provided at the ends of the surfaces to prevent overheating at such ends.  A magnetic field causes the arc to traverse the surfaces and may be modified in strength or distribution to vary traverse rate.  Also, by varying the magnetic field path, by superimposing another magnetic field or by gas pressure, the arc may be caused to follow paths which traverse entire surfaces even though arc cross-section is less than the width of surfaces.  The arc may be direct or alternating current and the magnetic field may be constant or variable in both magnitude and polarity. Sensors responsive to arc position may be used to control reversal of direction of arc movement, arc speed, magnetic field, etc.

Abstract: METHOD OF BONDING ELECTRONIC COMPONENTS            Abstract Disclosed is a method of bonding electronic components to metallized substrates by soldering.  The solder is first deposited on an unmetallized substrate in a pattern of discrete pads corresponding to the leads of the components to be bonded.  The component leads are then placed on the pads and the solder is reflowed.  The solder thereby adheres to the leads so that a controlled amount of solder will remain on each lead when the component is lifted from the substrate.  The components can then be soldered to an appropriate metallized substrate.
