Abstract: This invention discloses the phenomenon of physically sequestering organic soluble material by lamellar envelopment. It is to be distinguished from microdroplets of water insoluble drugs coated with a phospholipid prepared by sonication. Actual reduction to practice in a commercial effort has been with insect repellent. Hence, the disclosure will refer essentially to the dispersing of DEET.

Abstract: This invention relates to a method of prophylaxis with respect to Toxic Shock Syndrome in warm blooded animals, comprising the placing of a propylactically effective dosage of ascorbic acid in the vagina or in the area of the vagina.
Abstract: A catamenial device which is a tampon having a hollow or loosely packed central area and a forward end which flares open to a funnel configuration upon insertion into the vaginal tract of the user to cap the cervix and thereby direct menstrual fluid into the interior thereof. The tampon is removed by pulling a drawstring which is also a pursing string. The string first closes the forward end before exerting removal force on the tampon. Also, the body of the tampon is encased in a fluid barrier so that fluid is captured and retained within the tampon and absorption by the tampon from the vaginal wall is prevented.
Abstract: The disclosure teaches a new method of dental plaque removal and the structure of a brush bristle which enables the method most efficiently. A filament loop of contractable material such as polypropylene is caused to shrink as it is being attached to a base. The loop exhibits an extraordinary contraction wherein the loop is not merely reduced as expected, but by the process of this invention it contracts into tightly adjacent filaments with a tight return loop. The resulting bristle not only solves the vexing problem of proper bristle polishing, but as an unexpected additional value, exhibits a greatly improved capability to actually scoop away tooth deposits such as plaque.
Abstract: A keyboard entry device with video display for multiple language use. A language selector establishes the language mode of the machine, and the entire keyboard font is displayed on the video screen in the relationship of the keys on the keyboard. Display is either at operator request or machine controlled intervals and may be displayed on only part of the screen or the text being composed may be temporarily removed from the screen and the entire screen used to display the characters in a key related position. Thus, the operator has the capability of locating keys while learning the new keyboard relationship, or refreshing memory for reassurance.
Abstract: Apparatus for printing images on paper or other print medium by transferring toner on a magnetic tape onto the paper, using a voltage pulse applied between electrodes located respectively behind the tape and behind the paper. The electrode behind the tape is narrower than the tape, so that the opposite edge portions of the tape serve as insulators that prevent the formation of electric arcs between the electrodes. The voltage is applied in the form of a high voltage pulse on the order of 1500 volts lasting on the order of one millisecond, to transfer toner, and is followed by a sustained voltage on the order of 150 volts for preventing the toner particles from shifting position on the paper.
Abstract: The disclosure is a two-solution tray, each a substantial duplicate of the other, and each illustrating the principle of a chicken feeder supply, an overflow control that doubles as a drain cock and a sealed system drain container for ecologically safe disposal of spent chemicals.
Abstract: The device shown is a dual purpose unloader for the sheet holder bins of a paper distribution system, such as a collator. The bins of a collator are sometimes sloped to allow gravitational settling of the sheets as they are fed into the pockets. The illustrated unloader is an elongated open channel with an internal slidable rod. One set of grippers is mounted on the open channel and another set of grippers on the rod. A spring urges the two sets to move into a gripper closed position, and manual handles provide a means for opening the set of grippers. A mounting frame is available for guiding the unloader into proper registration with the collator pockets if manual placement is not convenient or desired.
Abstract: Apparatus for printing images on paper or other print medium, including a recording head which records magnetic images on a record tape, means for applying magnetically-attracted toner to the images, transports which hold the record tape and paper a small distance apart to leave an air gap of about 4 thousandths inch between them, a pair of electrodes located so that the toner on the record tape and the paper are sandwiched between the electrodes, and a high voltage source which applies a brief pulse of high voltage of a duration on the order of one millisecond between the electrodes, to form an electric field that propels the toner particles across the air gap from the record tape to the paper.
Abstract: The drawings illustrate a cassette only, to fit into any machine that uses a paper roll supply and requires accurate alignment of that roll supply with the processing machine. The cassette is bodily urged against one wall of the host machine in order to establish that wall as a reference. In the housing is a roll support core which is compound in that it has two members which are telescoped and spring-urged to expand. This will gauge the core against the wall of the housing that's engaged with the wall of the host machine. Then, the spring-urged slidable component of the core carries a positionable slide plate which, if the roll were not inserted, would come to rest at a position short of the roll length, and therefore constantly urges the roll against the cassette wall as a gauge of the roll by mesne gauge means with the host machine.
Abstract: A device for unloading a plurality of individual stacks of paper from individual compartments of a collator simultaneously. The device consists of a multiple set of grippers operated manually by a piston grip ratchet device. The grippers are registered with the stacks of the collator, the ratchet device operated to grip the several stacks, and the device with the stacks of paper gripped thereby removed to a convenient unloading station.
Abstract: An improved photocomposition machine is provided including a keyboard and a cathode ray tube (CRT) which displays various function commands, such as font, point size, and line length and their selected values, in a function field area on the CRT screen. Changes in point size and font values made by the operator within a line appear on the screen with the type line characters in a sequence which they were entered. Upon completion of a type line, the last selected point size and font values appear in the function field area as the completed line is shifted to a predetermined location on the CRT screen, whereby the operator is provided with a visual record of the point size and font values for both current and previous lines.

Abstract: A printing system of the type wherein magnetic images are recorded on a tape, the images are toned, the tape is positioned to extend adjacent to a web of paper, and the toner is then transferred from the tape to the paper. In the present system, the tape portion which passes by the image recording head and toner is moved continuously, while the tape portion which passes adjacent to the paper is moved intermittently by frictional engagement with a transport belt, a pair of vacuum column buffers being provided between the continuously and intermittently driven tape portions and supplying tape tension that holds the tape to the transport belt.
Abstract: A shaft encoder of negligible moment of inertia. A grating provides a grid pattern of transmitted light. A mirror on the shaft sweeps the pattern. A lens focuses the sweep over a mask of like grid pattern. A photocell is activated by light transmitted through the mask whenever there is a register of the grating image with the mask. By using a mask of N grid lines per unit of measure, and a mask of N plus 1, two cells will be able to detect direction of shaft rotation.
Abstract: A combination sheet-feed and utilization machine wherein the sheet feeder comprises an endless belt, or series of belts. The belt is driven in a path which is normally out of contact with a paper sheet stack and when a sheet is to be fed, the run of the belt between end supports is distended toward the sheet stack until contact is made and frictional engagement picks up the top sheet and begins it on its feed path. A retard mechanism prevents double feeding. The feed cycle is initiated by whatever means is convenient for the particular use, such as manual feed button or a machine cycle controller requesting another master, for example. The sheet travels to the utilization device, whatever type is being supplied, and when the sheet arrives at the utilization device in-feed, it triggers a sensor to initiate a circuit which ends the paper feed cycle and begins the utilization device cycle to pick up the paper from the feeder.
Abstract: The sheet diverting mechanism of a roller conveyor and belt combination sheet distributor operates in a sequential belt depressing mode by a three-roller deflector in a triangular configuration. The diverting mechanism can move in the direction of paper flow or counter thereto. The mechanism revolves about the roller centers, rather than to rotate about the center of the configuration. It follows a cyclic curved series of paths, producing a deflection of a subsequent belt area at a rate equal to a withdrawl of a prior belt area. The structure holding the roller deflector has great angular tolerance once the roller is in deflecting position. The two rollers, not in operation, can stop within several angular degrees.
Abstract: Apparatus for effecting a continuous remixing of magnetic toner material for development of an electrostatic latent image wherein a plurality of magnetic developing rollers are positioned with intersecting magnetic force fields for effecting a blanket of development material extending about and between the developing rollers adjacent an electrostatic latent image bearing surface. The apparatus differs from prior practice in that two mixer rollers are positioned on obtuse angular relationship with respect to the bottom one of the development rollers, with magnetic orientation and hand of rotation such that an orbital magnetic field is created above the mixer rollers in space, lifting all magnetic toner material out of the normal sump area and causing a mixing action and metering action of the development material.
Abstract: The drawings and specification set forth a structure in which one sheet at a time is dispensed to a utilization device, which is a table top and a belt drag conveyor. As the sheet is dispensed from the feeder, it trips a switch which starts the utilization device and turns off the feeder. The utilization device may be a photocopier table, for example, and the drag conveyor brings the document to be copied to a specific register line without the use of stops which might damage the forward edge of a document. The system is coordinated by a controller which will supply the documents to be copied at a maximum rate one after the other for collating, or on command, according to operator preference.
Abstract: A turret mounted series of photocomposing disc fonts wherein the turret has a series of disc hubs all having a different elevation in order that the disc members may be bunched together in overlapped relationship and hence occupy a minimum area within the photocomposing machine. The advance in the art is primarily in the placement of the discs in overlap relationship and then advancing or retracting the turret in order to accomplish proper positioning of the disc as opposed to the concept of the prior art in keeping all discs on one plane and then rotating the turret to bring each disc in turn into the optical system.
Abstract: In a photocomposition machine environment the apparatus and method show the concept of advancing the photosensitive material into position normally occupied for composition of text. The known apparatus and method are then modified by providing reverse leading for the paper and re-advance to the starting point followed by composition of a second column lateral to and aligned with the first column. A particular advance in the art is the ability to compose a complex mathematical formula with greatly simplified software using the improved hardware.The point of reference is established by a sensor which is activated upon advance of the paper to the sensor and therefore reversal and re-advancement of the paper will cause an exact repositioning of the paper for each column.
