Abstract: PURIFICATION PROCESS FOR PHOTOGRAPHIC  IMAGE-FORMING SULFONAMIDO COMPOUNDS              ABSTRACT OF THE DISCLOSURE       A process for purifying a photographic image-forming sulfonamido compound comprises the steps of:    a.   preparing a first solution by dissolving an unpurified image-forming sulfonamido compound in an aprotic solvent; b.   removing impurities from said first solution by, at least once: i.   mixing said first solution with an immiscible nonpolar, low-boiling organic solvent to form a mixture of said first solution and a second solution comprising said immiscible nonpolar, low-boiling organic solvent and at least a portion of said impurities, and ii.  separating said first solution from said second solution; and c.   recovering purified image-forming sulfonamido compound from said first solution. The process is useful in the purification of a nondiffusible sulfonamdio compound which is alkali-cleavable upon oxidation to release a diffusible sulfonamido color-providing moiety.

Abstract: TOOL FOR MANUAL RELOCATION OF ELECTRICAL. CABLES            Abstract of the Disclosure A tool for safe, manual shifting and manipulation of energized lines is provided which finds special utility in mines or other close areas where conditions of moisture and the like make it mandatory that electrical equipment be handled with great care.  The tool includes an elongated, insulative rod having, adjacent one end thereof, a pair of spaced, opposed, fixed, hook-like, spiral, cable-engaging fingers.  In use, the fingers are placed astride an electric cable or the like and the rod is rotated axially so that the fingers pass under and cooperatively engage and capture the cable therebetween, thus permit-ting easy shifting and movement of the cable. Particular features of the tool include the com-plete elimination of any mechanical moving parts, and the special configuration of the cable-en-gaging fingers permitting easy lateral shifting of a cable without fear that the cable will become disengaged and fall free of the tool.

Abstract: Abstract of the disclosure There is disclosed a security type hinge construction comprised of a pair of hinge leaves each having at least one adjacent knuckle and adapted for attachment to a door or door frame, or the like for accommodating pivotal movement there-between.  An electrical circuit component such as a switch is carried by one of the knuckles in a fixed orientation and operating means for the component is carried by the other of the knuckles, such that the relative pivotal movement of the hinge leaves can be employed to actuate or operate the com-ponent.  As such, the component can be wired in circuit to provide an indication of a change in the relative orientation of the hinge leaves, which correspondingly indicates a change in the position of the associated door with respect to its door frame.  The electrical circuit component or switch is further sealed within its associated knuckle, so as to sub-stantially preclude intrusion of moisture or the like, without regard for the orientation or mounting position of the hinge construction, which moisture if entering the hinge bore could result in short circuiting of the circuit component, thus negating the monitoring effect of the assembly.

Abstract: AUTOMATIC WASHER TRANSMISSION SHIFT MECHANISM            ABSTRACT OF THE DISCLOSURE A transmission shift mechanism for use in a vertical axis automatic washing machine having reversible rotary drive means has a drive gear on which is mounted an eccentric for translating rotary motion into oscillatory motion in a plane perpendicular to the washing machine axis.  The oscillatory motion is transmitted to the agitator shaft of a washing machine by a rack and pinion.  The pinion is rotatably mounted on the agitator shaft and has teeth on a lower surface thereof which engage teeth on an upper surface of a sleeve co-rotatable with the agitator shaft to form a jaw clutch for driving the agitator shaft from the rack and pinion.  A shifter fork also connected to the eccentric operates cams to raise the pinion out of engagement with the sleeve to disengage the jaw clutch when the eccentric is rotating in a first direction, and returns the clutch teeth to engagement when the eccentric rotates in an opposite direction.

The nozzle inlet is dimensioned to effectively cover one or more two cell filter modules formed by the filter media separators.  A vacuum or induced draft is applied to the nozzle to provide a cleaning air flow counter to the flow of particulate air through the filter. The nozzle temporarily blocks or retards the flow of particulate air through the module or modules being cleaned while the flow and filtering of particulate air continues through the remaining major portion of the filter.  Means and their corresponding method of opera-tion for maintaining the nozzle in contact with the filter inlet face and for moving the same across the filter face for sequential cleaning of the filter modules are also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE        A digital pad switch is inserted in each highway of a time-division speech network in which there are disposed on the backward side of the speech network time switches, each reading out speech information from a speech memory in the order of address, assigning the memory address by the output from a channel counter.  The digital pad switch is arranged so that it may send out, under the control of a common control unit, a selected one of the same signal as an input signal from each path to the digital pad switch, signals respectively having attenuated the input signal by predetermined amounts and a zero level signal regardless of the magnitude of the input signal.      In the case of cutting off a speech path set up in the time-division speech network, the digital pad switch is con-trolled by the common control unit to send out the zero level signal as a signal of the speech path passing through the digital pad switch, and after writing the zero level signal in the speech memory of the time switch on the backward side, the speech path is cut off.    A continuous tone signal passing through the time-divi-sion speech network is inputted to the digital time pad, which is controlled by the common control unit to selectively send out the zero level signal for a desired period of time, thereby turning ON and OFF the tone signal.  In the case of sending out a howler tone, the amount of attenuation of the tone signal is decreased by the control of the common control unit in a stair-step manner.  In the case of testing a multi-frequency signal receiver, a multi-frequency signal transmitter and the multi-frequency signal receiver under test are connected to the backward and the forward side of the time-division speech network, respectively, and a path is set up between them and then a signal on the path is attenuated variously by the digital pad switch to vary the level of the input signal to the multi-frequency signal receiver.      Thus, the present invention permits efficient use of the digital pad switch.

Abstract: Abstract of the Disclosure An optical fiber is produced with a graded index core, the core forming material being formed, or deposited, at high rates with a small number of layers, relative to conventional methods.  The profile of the refractive index has very "coarse" or stepped form.  While the modal dispersion can be larger than a conventional fiber, the overall modal dispersion of a transmission line composed of a plurality of lengths joined together does not increase at such a rate as with a conventional fiber.  Also the fiber can be less sensitive to wavelength.  As a result fiber, preforms, and transmission lines and cables, can be produced cheaper and yet still meet specification standards.
