Granted: 1980-04-08
Abstract: ABSTRACT OF THE DISCLOSURE          Processes for the production of novel 2-deoxystrept-amine aminoglycosides by alkylation of an appropriate amino-glycoside or aminoglycoside derivative are disclosed.  The compounds of the invention have an amino group on the l-position which is substituted with an alkyl group bearing one or more hydroxyl groups on carbon atoms other than those linked to the amino group.  Such compounds are effective in treating bacterial infections and have been found to possess lower toxicity than many known aminoglycosides.

Abstract: ABSTRACT OF THE DISCLOSURE    An inductance-capacitance loop defines a resonant circuit and is arranged in a member subject to stress.  Strains re-sulting from the stress vary the inductance or capacitance of the circuit, and its resonant frequency.  A dip meter is used to detect the resonant frequency and thus provides a reading indicative of the stress in the member.

Abstract: IMPROVED CATHETER OXIMETER APPARATUS AND METHOD     ABSTRACT OF THE DISCLOSURE         An improved catheter oximeter operates on radiation at three or more different wavelengths applied to and scatter-ed back from blood under test to provide an indication of oxygen saturation and is considerably less sensitive to accu-racy degrading variations in the blood and its environment and in the oximeter measuring system.  Typically there is produced a corresponding electrical signal representative of the intensity of the radiation received back from the blood under test at each of the three wavebands.  A first output is produced which is representative of the ratio of one pair of electrical signals.  A second output is produced which is representative of the ratio of another pair of the electrical signals.  Third and fourth outputs representative of the algebraic combination of selectively weighted first and second outputs are produced, and an output manifestation of oxygen saturation is produced as the ratio of the third and fourth outputs.

Abstract: ABSTRACT OF THE DISCLOSURE                 A method and apparatus for detecting and correcting the occurrence of flashover in a direct current electric motor.  The polarity and magnitude of voltage on the field winding of the motor is continuously monitored.  Detection of a sudden reversal of the polarity of the field voltage accompanied by a rapid increase in magnitude results in the generation of a flashover signal.  The flashover signal is coupled to power controlling elements regulating power supplied to the motor and is effective to force removal of power from the motor.  In a preferred embodiment the appartus is disclosed in a two-motor system with two field windings serially connected such that the field voltage monitoring is accomplished on a differential basis.

Abstract: ABSTRACT A make-before-break printed circuit board edge connector comprises a plurality of pairs of terminals arranged in a row with a housing having side walls snapped there over.  The housing has an elongate slot therein for receiving an edge portion of a printed circuit board.  Each of the terminals is staked to a support and has a main bowed portion extending upwardly into the housing with the concave side thereof facing an adjacent side wall of the housing and with the convex side thereof facing the convex side of the main bowed portion of the other terminal of the pair, the printed circuit board edge being insertable between these convex sides.  Short circuiting contact arms, also bowed, are stamped from the main bowed portions.  Each such contact arm is attached at its upper end to the top of the associated main bowed portion, is free at its lower end and extends downwardly with the convex side thereof facing and nearly or actually abutting the inner surface of the housing side wall adjacent to the main bowed portion from which the contact arm is stamped.  The free ends of the contact arms touch each other below the convex surfaces of the main bowed portions of the pair of terminals to form a continuous electrical path through these terminals, which is not broken by the edge portion of the board until after the main contact portions mate with the printed conductors of the board.
