Abstract: A mixing device comprises a first cylinder (10) containing a particulate or powdered component (11) and having a closed first end (13, 14) and an opposite second end which is closed by a piston-like venting and filtering assembly (12, 15). The device also comprises a second cylinder (18) containing the liquid component (19) and having a closed end (20, 22) and an opposite open end sealingly receiving the closed end of the first cylinder (10) therein in a piston-like manner. Means (14) are provided for communicating the inner space of the first and second cylinders (10, 18) through the closed end (13, 14) of the first cylinder (10), when the first cylinder is forced into the second cylinder, whereby liquid from the first cylinder is injected into interstices defined between the particulate component contained in the first cylinder for providing a paste-like material. The communicating means is preferably formed by a breakable membrane (14). The venting and filtering assembly (12, 15) may be used as a piston for discharging the paste-like mixture made from the first cylinder (10). The mixing device is preferably used for mixing components so as to form a bone cement.

Abstract: Apparatus for generating of a comb having a large number optical teeth and comprises an optical loop (3) including an optical amplifier (5) a frequency shifter (4) and an optical filter (6). A signal from a laser (9) is partially coupled into the loop by a coupler (7) such that a part of it is output at output port (10). The signal in the loop (the feedback signal) is amplified by the amplifier (5) and frequency shifted by the frequency shifter (4) and is then partially coupled out of the loop by coupler (7). The part coupled out of the loop (the output signal) exits via output port 10. This process is repeated to produce the desired number of output signals exiting via output port 10. The signal from the laser (9) may be continuous or pulsed.

Abstract: A device for controlling beams of particles, X-rays and gamma rays including a plurality of channels with total external reflection inner surfaces, input butt-ends facing a radiation source and output butt-ends aimed at a radiation receiver is taught. Channel-forming elements are in the form of surfaces, tubes, and structures with multiple channels and are rigidly positioned one relative to another with a spacing between suports such that the sagging of the channel-forming elements does not interfere with beam propagation. The device can be used to capture radiation from sources which produce parallel or divergent radiation. The resulting beam or beams can be of a variety of shapes or angular orientations including quasi-parallel, convergent, and split beams. Energy filtering is accomplished by selective absortion of radiation by the channel-forming elements and by selective reflection, by geometrics which cause some energies to be discriminated against because of the angle of total external reflection associated with that energy. Also provided are embodiments which use these devices for improved medical imaging, medical therapy, X-ray lithography, and analytic instruments.

Abstract: The invention relates to a process of storing data on, or retrieving data from, a plurality of disks (15). In one embodiment the process uses up to four commercial disks (15) in parallel to increase bandwidth and capacity. To store data onto the disks (15), the data in the main memory is divided into segments numbered modulo 4, and each disk (15) then accesses and stores the same numbered segments. There is no master disk, and each disk (15) stores data asynchronously at its own speed. The system is transparent to the user in that it appears to be one disk. For retrieval from the disks (15), each disk (15) supplies its segments, which are then assembled in memory. <IMAGE>

Abstract: This invention covers a composition for forming an applique for cleaning or treating skin comprising a lower alcohol or alcohol/water solvent in which is dissolved between 0.1 to 20 % by weight/volume of a polymer consisting essentially of a non-acrylate pre-polymerized high molecular weight, dermatologically acceptable, adhesive polymer. The cleansing is accomplished by applying the formulation to skin as an applique, drying the applique, contacting the dried applique with an adhesive tape type material which bonds with the applique, and then pulling the applique/tape away from the skin. These skin cleansers are based on certain naturally occurring and synthetic polymers which are soluble in simple alcohols, or simple alcohol and water mixtures. It has been found that the selected polymers remove surface and follicular debris when formulated and applied without additives which modify their native configuration. Adding polymerizing agents or cross-linkers to the selected polymers reduces the capacity of these appliques to effectively remove soil. Thus polymers are pre-formed, that is they are not presented as monomers and cross-linked when applied to the skin.
