摘要： A positively lockable angularly adjustable handle for portable apparatus is substantially U-shaped and includes two parallel arms interconnected at one end thereof by means of a transversely extending bar and having inwardly projecting tubular journal members at the other ends thereof for mounting the handle within apertures provided within the apparatus. Upon the external surface of the journals there is located, in serial fashion, a peripheral flange, arcuate stop members, and a series of splines, a circumferential bearing surface being interposed between the flange and the stop members and a circumferential recess being similarly interposed between the stop members and the splines. The inner peripheral walls of the apparatus defining the apertures include an inwardly projecting flange and mating splines whereby the journal members may be forced axially inwardly within the apertures to a first position wherein the aperture flange is housed within the journal bearing surface so as to prevent further relative axial movement and the splines are disengaged so as to nevertheless permit free angular movement between the handle and the apparatus, and the journal members may be forced axially inwardly within the apertures still further to a second position whereby the splines interengage so as to prevent angular movement between the handle and the apparatus, the apparatus flange being housed within the recess to again prevent further relative axial movement. Axial retraction of the journals to the first position permits the handle to be adjusted to a different angular position whereupon the same may be once again positively locked against angular rotation relative to the apparatus.

摘要： A typical embodiment of the invention discloses a technique for joining structures. For instance, to provide a heat-resistant vacuum seal in a photomultiplier tube, a mechanically deformable material is interposed between tube components. The deformable material is seated in complementary grooves formed in opposing component surfaces. The components then are compressed together with sufficient force to exceed the elastic limit of the interposed material in order to distort the material and enable it to flow plastically into the grooves and thereby lock the components together.

摘要： An apparatus for editing information to be presented to a display to remove unwanted leading zeroes. The apparatus includes logic circuit means for accepting information about the digit and the preceding digit and then deciding whether or not to blank the digit. If the blank decision is made the logic circuit provides an inhibit signal. The information provided to the logic includes a signal indicating that the digit be examined is or is not a zero; a signal indicating whether or not the preceding digit was blanked or that this is the first digit; and a signal indicating whether the digit under examination is immediately preceded by a decimal point. The digits examined in an ordered sequence beginning with the highest ordered digit and proceeding toward the lower, each digit being examined in a well-defined time interval and either blanked or not blanked before the next digit is examined.

摘要： An illustrative embodiment of the invention is directed to method and apparatus for manufacturing microchannel devices. Typically, the individual glass tubes in a hexagonal bundle are sealed on one end to individual hangers from which they are suspended vertically in a furnace. A vacuum is drawn within the furnace so that the inner surfaces of the tubes, exposed to atmospheric pressure, will not collapse during heating and drawing. At temperature, the bundle is drawn and elongates under the controlled forces applied through a modified Atwood''s machine to reduce the bundle cross section by a ratio of about 50 to 1. The elongated bundle is cut into lengths as it is drawn, and these individual lengths are stacked together within a tube of glass that has a higher melting point than the glass in the drawn lengths. The channels are once more sealed and the assemblies are subjected to a secondary fusion process prior to slicing into thin discs. The annular glass rings are removed from the discs and the microstructures are placed in a molten wax bath in order to fill the channels with wax before grinding and polishing. After grinding and polishing, the wax is removed.

摘要： D R A W I N G
AN OPERATIONAL RECITIFER OR CONVERTER INCLUDING A SERIES RC CIRCUIT TO CONDUCT AN AC SIGNAL TO A SUMMING JUNCTION AND A SECOND CIRCUIT PARALLEL TO THE SERIES RC CIRCUIT FOR DEVELOPING A DC COMPONENT AND AN INVERTED AC COMPONENT TO CANCEL THE AC CONDUCTED BY THE SERIES CIRCUIT. THE SECOND CIRCUIT INCLUDES AN OPERATIONAL AMPLIFIER HAVING TWO IDENTICAL DIODE-RESISTANCE FEEDBACK CIRCUITS. THE DC COMPONENT AND ONE HALF OF THE AC COMPONENT IS TAKEN FROM ONE FEEDBACK CIRCUIT THROUGH A RESISTOR, AND THE OTHER HALF OF THE AC COMPONENT IS COUPLED FROM THE OTHER FEEDBACK CIRCUIT THROUGH A CAPACITOR, TO THE OUTPUT TERMINAL. A SECOND EMBODIMENT SHOWS SUPPRESSION AND COMPENSATION CIRCUITS TO REFINE CIRCUIT OPERATION.
