Granted: 1981-07-28
Abstract: ABSTRACT OF THE DISCLOSURE                    An exposure control for a camera of the type having scanning type shutter blade elements driven by a walking beam to provide a progressive variation in effect-ive exposure and light sensing apertures.  A control is provided so that in an artificial scene lighted mode, during an exposure cycle, the scanning blades cause the effective exposure aperture to progressively increase toward the full open f/stop for the camera.  In addition, the scanning blades cause the effective photocell aperture to increase at a relatively low rate until a time when the effective exposure aperture equals a  predetermined f/stop somewhat below the full open f/stop.  The source of artificial illumination is then fired and the effective photocell aperture increases at a relatively high rate to specifically control the artificially illuminated portion of the exposure cycle.  In a natural or ambient scene lighted mode, the control provides for the scanning shutter blades to cause both the effective exposure aperture and the effective photocell aperture to progressively increase to predetermined aperture sizes less than the maximum aperture sizes of the artificial scene lighted mode.

Abstract: ABSTRACT OF THE DISCLOSURE           Method and apparatus are disclosed for continuously framing and steaming discrete segments of tubular knitted fabric, particularly sweater body segments and the like which are con-structed to include a body section provided with a cuff at one end.  The process and apparatus provides for differential width stabilization of the segment, such that the body portion is set at one width and the cuff portion is set at a slightly narrower width.  Individual segments are advanced over a spreader frame and distended to the desired width for the body portion.  The section is discharged, cuff first, off of the spreader and enters between a pair of conveyor blankets.  The blankets are held in noncontacting relation, initially, to permit the cuff to return to narrower dimensions, but the blankets then close upon the segment, so that the body portion thereof is maintained at an increased width.  While the segment is thus engaged, it is steamed to stabilize its geometry.  Of particular importance, unique provisions are made for effecting lengthwise stretching of the segment without uncontrolled loss of width such that, when the segment is gripped by the conveyor blankets, its geometry has been desirably adjusted both lengthwise and widthwise. The invention enables substantial duplication by automatic machinery of operations which heretofore have been carried out largely manually on a one-at-a-time basis.

Abstract: ABSTRACT         A telephone switching system for a plurality of telephone lines in a telephone network, each line being con-nected to a port.  The ports monitor and control signals on the lines, and transmit and receive voice signals that are coupled through a supervisory store.  A call processor controls the switching network and, by transferring information with the supervisory store, also controls the port event processor.  The port event processor also uses the information stored in the supervisory store to control the ports.  The port event proces-sor also retrieves the sequentially-stored supervisory signals from the storage means, filters them and uses them in its con-trol of the ports, and updates the information in the supervis-ory store.  The port event processor filters the stored super-visory signals by receiving successive time samples of the supervisory signals and generating a signal that reflects the majority of the sampled signals as the filtered supervisory signal.

Abstract: ABSTRACT         An automated analysis process and apparatus for analyzing the amount of dispersed water-immiscible solid organic substances in sewage water whereby a precise sample of sewage is taken from a sewage source, admixed with various reagent solutions, including a K2Cr2O7-solution under heat-time conditions so that a reaction occurs between the sewage and the reagent and all of the organic substance in the sample are oxidized while simultaneously at least some Cr+6-ions are reduced to Cr+3-ions.  During this oxidation-reduction reaction and at a location remote therefrom, a precise amount of Fe+2-ions is generated within an aqueous acidic Fe+3-ion containing solution via a coulometric reduction process.  Thereafter, the reacted sewage-reagent solution is admixed and reacted with the so-generated Fe+2, Fe+3-ion con-taining solution so that any residual Cr+6-ions in the sewage-reagent solu-tion are reduced to Cr+3-ions and at least some Fe+2-ions remain.  By amperometrically titrating the resultant Fe+2-ion containing solution with a standardized Cr+6-ion containing solution, the precise amount of Fe+2-ions within the titrated solution is determined and this provides an indirect indication of the amount of organic substances within the sewage sample. Pneumatic, hydraulic and electrical circuits actuate the various steps and are themselves actuated and controlled by a master control means, such as preprogramed computer means, which also computationally integrates data from the overall process and automatically determines the amount of organic sub-stances in the samples under analysis.

Abstract: IMPROVED PERMANENT CALENDAR                 Abstract of the Disclosure An improved permanent calendar assembly adaptable to display any month of any year.  The construction includes a flat main body with forwardly protruding tracks for removable mating with date columns.  For flexibility of display, blocks or end pieces carrying one of the dates "29", "30" and "31" on one surface and a blank on an opposed surface are rotatably or removably mounted onto the date columns so that either side of any of the blocks may be selected for display.  The calendar also features a construction that allows easy removal and rearrangement of the vertical date columns and yet prevents their disengagement when, for example, when the calendar is tilted forward.  At least one lipped horizontal track extends across the date column area.  Defined in the back wall of each date column are at least two openings or grooves that can mate with the track, as desired.  The lip results in a track with surfaces facing in more than one direction and particularly with an engaging surface which has surface normals with no upwardly directed component.  This engaging surface mates with an opposed surface in each date column groove when the calendar is tipped forward to prevent the date column from falling.  A support stand is pivotally secured within a cut out in the back wall of the calendar frame.  A compressing spring is positioned in the body to bias the stand into frictional engagement with one of the side walls of the cut out so that it will not move from a position in which it is placed..

Abstract: ABSTRACT     A high speed method and machine for imprinting coding indicia on articles travelling in a line along the upper reach of a conveyor at an imprinting zone.  The containers travel to the imprinting zone through a worm feed.  Gripping force is applied to the containers at the imprinting location to immobilize same momentarily during imprinting.  A pivotally mounted inking and printing assembly, including a multiple head printing wheel, is employed and is raised and lowered as a unit without stopping the machine. A single motor drives the machine but each member of the ink/supply and transfer means of the inking and printing assembly may have relatively different circumferen? speeds of rotation.  The ink applicator thereof operates at a variable speed independently controlled selectively to vary the quantity of ink applied upon each rotation of the receptor ath therefor.  The speed of the conveyor is controlled in relation to the number of printing heads on the printing wheel.

Abstract: D-20,721 PROTECTION CIRCUIT FOR CONTROLLING THE EFFECT OF INDUCED          CURRENTS ON LINE SIGNAL REPEATERS              by Edward T. Ball ABSTRACT OF THE DISCLOSURE           Operating power for line signal repeaters is fed over a transmission cable pair (signal line) which is susceptible to lightning strikes and, thus, to longitudinally induced currents in the DC power feed circuit.  A symmetrical non-linear protection circuit is connected between the signal line and the line signal repeater, and includes a high current shunt regulator which by-passes excessive induced currents.  By so doing the adverse effects of these induced currents on the operation of the line signal re-peater is minimized.  A shunt voltage regulator provides the line repeater  with a constant operating voltage when the line current (DC line power feed current plus induced currents) is greater than the minimum required bias current.  When the potential at input terminals of the protection circuit exceeds a predetermined value, a portion of the excess current is conducted through a blocking diode to charge an energy storage device.  But, when the DC line power feed current and the induced current oppose each other the energy stored in the energy storage device is used to supplement the power feed current to just maintain the required repeater voltage, until the potential decreases below the operating voltage.
