Abstract: A system is disclosed for the automation of virtually all clerical functions in an office, such as for example, an insurance agency. Virtually any document generated by the office may be printed without the need for pre-printed forms, as the system prints such forms on a laser printer near the worker requesting the form, using a page description language (PDL) appropriate to the printer. The clerical activity involved in maintaining, updating, retrieving, displaying and printing information relating to the functions of the office is supported.A complete audit history of all activity to a specific database (DB) file record is maintained without saving the entire DB record in a historical file. The system also supports a worker when it is desired to interrupt a particular task and execute a different task, without losing information already entered for the first task, but without allowing the worker to exit the system without completing or accounting for the first task.

Abstract: A open-framed and lightweight inverter power source rack made from aluminum that offers the versatility of providing varying amounts of power sources from a single branch circuit external power supply. A first rack can act as a stand-alone power supply for up to four power sources. A second or slave rack detachably connects with the first rack as the need for power sources increases on a job site. The slave rack is fed from the same external power supply as the first rack. As the need for power sources on the job site decreases, the slave rack may be disconnected from the first rack and connected to another rack where additional power sources are required. Moreover, inverter power racks are adapted to be shipped and transported in knock-down, disassembled state for final partial assembly by the user to reduce shipping and manufacturing costs.

Abstract: An exercise apparatus adapted to provide resistance to an exercising user who attempts to induce an exercise stroke of the apparatus and which is also adapted so that once the exercising user has initiated the exercise stroke along the stroke path the user may: (1) continue to exert a force along the stroke path; (2) exert a force opposite the exercise stroke path, this force will also be resisted by the apparatus; (3) exert no force, in which case the apparatus will continue the exercise stroke path; or (4) the user may initiate some combination of the above actions. The exercise apparatus being further adapted so that gravity and friction do not have a significant effect on the resistance or assistance that the user confronts. Embodiments of the invention encompass exercise stroke paths in up to three dimensions, whereby the user may perform linear, rotational, or a combination of both movements in exercising with the apparatus.

Abstract: A hair tie to fasten locks of hair into pony tails, braids or dred locks. The hair tie comprises a generally planar, elongated material containing corresponding fastening surfaces at each end. The hair tie encircles the lock of hair in a belt-like fashion and fastens upon itself. The hair tie is capable of tying different amounts of hair by varying the positions the ends of the hair tie engage. Additionally, the hair tie incorporates an elastic loop and a friction pad to ensure the hair tie securely attaches and remains in position on the lock of hair. Ornamentation, such as jewelry, beads and ribbon, printing and logos may decorate the hair tie, allowing individuals to decorate their hair as well as fasten it.

Abstract: An enclosed cage adapted to transport and transfer animals, particularly primates, whereby the animals are transferred from the cage without any physical contact between the animal and its handler. The cage comprises a back panel slidably connected to the frame and a floor pivotally connected to the front end of the cage and rotatably connected to the base of the back panel. The floor is generally coextensive with the width and height dimensions of the interior portion of the cage. The sliding motion of the back panel causes the floor to raise from its normal horizontal position and sweep through the interior of the cage until it opposes the front opening of the cage thereby effectively forcing the monkey to exit the transport cage.

Abstract: A religious article that first functions as a canopy or chuppah for a wedding ceremony and then when cut into pieces serves as individual prayer shawls or tallitot for the couple. The religious article has two rows of heavy stitching, each adjacent to a longitudinal or latitudinal axis and perpendicular to the weft or warp of the material. The religious article also contains four reinforced corners and four additional reinforced areas each having holes provided therein. When the religious article is cut along the axis, forming two prayer shawls, each shawl has reinforced corners with holes through which are attached braided religious fringes or tzitziyot.

Abstract: A safety needle and cap combination is disclosed which significantly reduces the chances of a needlestick injury when recapping the needle. The cap is pivotally attached to the needle hub, and has a longitudinal slit to accomodate the needle. In an alternative embodiment of the invention, the cap cannot be pivoted open until the needle cap is slid out along a guide to a detent position. Closure can be done with one hand, well away from the needle point, by pressure against a convenient surface.

Abstract: Polypeptides in the size range 6-11 amino acids from discrete regions of the human immunodeficiency virus p17 protein are immunogenic and form the basis for diagnosis and therapy of HIV-related disease.

Abstract: This device is an automatic faucet with three temperature settings activated by a pressure switch which is mounted on or near the floor by the user's foot. The invention includes a device which will, after a period of time, automatically turn the water off after the switch has been depressed. In the preferred embodiment, the user upon approaching the sink, could, by viewing indicator lights, readily discern whether a hot, cold or warm temperature setting has been selected.

Abstract: A method and apparatus for on-site removal, efficient cleaning, and expeditious restoration to service of the diffuser lenses, i.e. diffusers, lenses, and reflectors, used in fluorescent lighting fixtures. The apparatus employs dual immersion chambers, deep troughs, filled with a liquid medium suited to ultrasonic transducer agitation. It comprises a rectangular cabinet, having longitudinal slots in the top that provide external access to the troughs. The narrower trough, with appropriate liquid contents, serves as the initial scrubbing or washing chamber, while the wider trough, with differing liquid contents, serves as a rinsing and article-recoating trough. An ultrasonic transducer is horizontally disposed within a niche in one of the walls of the wash trough. Diffuser lenses are cleaned by detaching them from their fixtures, placing them one at a time into the washing trough, where they are cleaned by ultrasonic liquid agitation, and then into the rinsing trough.

Abstract: A kit and method have been developed which can be used to simultaneously detect antibodies to two HTLV or HIV antigens. The kit includes a solid carrier material, such as a microtest plate, having immobilized thereon a mixture of first and second viral antigens. The antigens are from any of HTLV-I, HTLV-II, HIV-I and HIV-II provided, however, that HTLV-II antigen is mixed only with HTLV-I antigen. The kit also comprises labeled-antibodies which are reactive with both the first and second antibodies in a test sample. A biological sample, such as a blood sample, is assayed by contacting it with the immobilized antigens to form reaction products between the immobilized antigens and the antibodies in the sample, followed by contact with the labeled antibodies to form labeled reaction products which can be detected in a suitable manner. The kit and method are useful for rapid screening of biological fluids.

Abstract: A method and apparatus are disclosed for measuring the degree or rate of mixing in a turbulent liquid system. The method involves inserting into the liquid system a probe capable of responding to variations in a chemical or physical parameter which can vary in the system, e.g. pressure, velocity, acceleration, pH value, conductivity or temperature. A signal from the probe indicating the parameter is processed by transforming it to a readable electronic output and this output is then compared with a calibrated range so as to enable the mixing process to be monitored or optimized.

Abstract: It is proposed to increase the utility of intracellular fluorescence and absorbance measurements for control of fermentation and cell culture by correcting on-line for background fluorescence of the media, also to be able to measure the fluorescence or absorbance of the fluid media in the presence of suspended cells or particles. The measurements could be extended to measure the optical properties of other fluids which contain suspended particles. This invention uses the characteristics of the evanescent wave at the surface of an optic waveguide. The wave penetrates into the less dense medium only to about the depth of about 1/2 wavelength. The thickness of media swept by the evanescent wave is much less than the size of a cell, thereby essentially separating the fluorescence or absorbance of the media from that of the cells.
