Filed: 1978-12-22
Granted: 1981-06-02
Abstract: ABSTRACT OF THE DISCLOSURE                  This device is of the type comprising a frame (1) and two rollers (4a,4b), which are mounted to rotate on this frame, about parallel axes.  The band (5) is fixed at both ends to these rollers. Means (6-7) for driving in rotation at least one of the rollers and means (12-20-19) for regulating the tension of the band between the roller are provided.  The means for driving in rotation are means which are constantly engaged with the corresponding roller and the means for regulating the tension of the band are means for relaxing the tension of the active  part (8a-8b) of the driving means and means for simultaneously increasing the tension of the passive part (8c) of the driving means.

Abstract: ABSTRACT OF THE DISCLOSURE           A nib retaining assembly for a writing instrument to hold a capillary writing element or nib of small cross-sectional dimension in position against writing pressure, the nib retaining assembly including a nib receiving main longitudinal passageway formed by offset portions through which the capillary element extends.  The capillary element is held by light staking within an axial bore of a nib holder which, in turn, is inserted into a seat at one end of the passageway.  Because of the passageway offset portions and an intermediate camming surface, a capillary element inserted into the passageway is deflected around an internal shoulder so as to be forced into frictional engagement with the passageway walls to hold the small nib in writing position without disturbing the capillary action.  In one embodiment of the invention, the passageway is defined by a nib retaining adapter inserted into a seat in the barrel; while in another embodiment the passageway is defined by the tubular barrel of the instrument. A single nib retaining assembly will accommodate nibs of many different diameters.

Abstract: 13,9.78                     1                      PHN 9112 ABSTRACT: "Transmission system for the transmission of data pulses."     Transmission system for the transmission of data pulses from a transmitter to a receiver, which utilizes the principle of quantized feedback for reducing the intersymbol interference. The forward filter and the feedback filter in the receiver are recursive filters compared to non-recursive filters in applications in accordance with the prior art, and use three or more poles which are the same for both filters in the transfer functions as dompared to prior art simple first or second order networks. A relation has been developed between the numerator polynomials of the transfer functions of the two filters together with a synthesis of the forward filter for reducing the intersymbol interference and the noise for a given stability of a bandwidth-limited system.

Abstract: ABSTRACT OF THE DISCLOSURE           A sleeve member formed from a pipe length by expansion is placed over a mandrel onto which are wound the spaced turns of an electric resistance heating wire. By heating the sleeve member the latter is shrunk onto the turns.  By electrically producing heat in the wire, material flows around the expanding turns and embed the latter completely in a sleeve member projecting material portions being formed in the vicinity of turns.  Thus, protection against electric shock hazards is obtained for turns and subse-quent working is made unnecessary for the recessed edge portions of inner wall which deform inwards during manufacture.

Abstract: BOUNCE-RESISTANT CONTACTS FOR A SWITCH           ABSTRACT:  a bounce- and weld- resistant contact assembly includes a pair of spaced contact plates with facing contacts on their ends.  A switch blade is rapidly movable into and out of engagement with the contacts.  The contacts are convexities coined into the plates which add no mass to the plates.  Thus, the natural frequency of the plates is maximized and the magnitude of oscillation of the plates, when the con-tacts are rapidly engaged by the blade, is minimized.  Legs on leaf springs act against concavities formed in the plates opposite the convexities.  The legs conformally nestle in the convexities so that their frictional engagement therewith and the spring force co-act to quickly damp the high frequency, low magnitude oscillations of the plates.  The low mass coined contacts also permit close spacing of the plates to maximize magnetic forces thereon due to current flow therethrough. These forces aid the spring and the leg-concavity friction in quickly damping oscillations of the plates.

Abstract: Abstract of the Disclosure Stabilized enzymes useful in the diagnostic assay of total cholesterol are prepared by dissolving a salt of cholic acid in a buffer solution providing a pH within the range of a?out 4 to about 9, to the solution is added a cholesterol esterase.  The solution is then mixed with a polyhydroxy organic compound and TRITON-X-100.  A cholesterol oxidase and a peroxidase are each dissolved in separate portions of buffer solution and introduced into the buffered solution containing the cholesterol esterase.  4-aminoanti-pyrine is then added to the solution.  The resultant solution is a stabilized enzyme solution which can be used in the total cholesterol assay of a serum sample.  The stabilized solution can be used in combination with a chromogen diluent solution which is made by dissolving pnenol and TRITON-X-100 in water or a buffer solution.   The combination of the stabilized enzyme solution and the chromogen diluent solu-tion provides a solution which has utility in the spectro-photometric assay of total cholesterol.

Abstract: Abstract of the Disclosure An automatic typefont loader is sequenced to change the printwheel typefont of a printer.  An elongated rack supports plural picker holders along its length and is normally located beneath the platen of the printer.  Typefonts to be exchanged are held by the picker holders.  During an exchanging sequence, the typefont carrier which is positioned along the platen to effect printing at discrete printing positions is positioned to a discrete printing position adjacent an empty picker holder for a typefont unloading operation.  The elongated rack is then elevated so that the empty picker ??lder contacts the typefont.  The typefont is removed from its carrier by moving the typefont carrier perpendicular to its normal motion.  The picker holder rack is then withdrawn and the now empty typefont carrier is positioned to a second discrete printing position adjacent a selected typefont located on a picker holder. The picker holder rack is elevated and the typefont carrier moves toward the selected picker holder to retrieve a typefont.  The operation is completed with the withdrawal of the rack to its normal position beneath the platen.
