Abstract: Wound Dressing Comprising Silver Sulfadiazine Incorporated in Animal Tissue Abstract of the Invention Animal tissue and the like having silver sulfa-diazine incoprorated therein is useful as a covering for burns and/or wounds.  The silver sulfadiazine is incorporated in the tissue by soaking the tissue in an ammoniacal silver sulfadiazine solution or suspension.          When the silver sulfadiazine is so incorporated in the tissue via an ammonium solution, more silver is found to be present than would normally be expected and the effectiveness of the thus treated tissue as a wound covering increases.     Background of the Invention This invention relates to a process for preparing a dressing or covering for wounds and/or burns.  Animal tissue has long been known to be a useful source of material for wound coverings.  Although not identical to human skin, the composition and usefulness of some ani-mal tissue resembles human skin.  For example, a covering for wounds, ideally, both protects the wound against contact with moisture and external contaminants, while also being permeable to the excretions, in particular, water vapor, which are produced by normal metabolic processes.     Silver sulfadiazine (AgSD) is known as a useful antimicrobial in the treatment of wounds, and of burns in particular, see U. S. patent 3,761,590 (1973), Fox;          Bose, Storing Amniotic Membrane in Silver Sulfadiazine Suspension, The Canadian Medical Assocation Journal, 127, No. 2, p. 112 (July 15, 1982); Fox, Modak and Stanford, Silver Treated Graft Materials for Coverage

Abstract: "PHYSICAL EXERCISER" ABSTRACT OF THE DISCLOSURE A physical exerciser is provided which utilizes a pair of compression springs. The springs are maintained in a spaced apart, parallel, side-by-side , straight state by an assembly comprising an inner guide member and an outer tube circumscribing said member.  The springs extend longitudinally in troughs formed in the peripheral surface of the elongate guide member.  The troughs extend parallel to the longitudinal axis of the tube.  The tube holds the springs in place in the troughs.  The assembly further provides a stop at one end of each spring, to fix that end against displacement.  A pair of tubular handles are mounted on the tube, one at each of the tube's ends.  Each handle includes a pin extending transversely across the free end of one of the springs.  Suitable slots are provided in each end of the guide member and tube, so as to allow the handles to slide inwardly, each such handle acting to compress one of the springs.  There are thus duplicate means at work in the single tube - each means comprises a spring, its stop, the handle and pin which can compress the spring, and the slots which permit the pin to travel.  The spring, pin and slots of each means lie in a common plane.  The two common planes for the two means are disposed at 90° to each other.  The exerciser thus has two handles, each operating independently against its own spring, which may be forced inwardly simultaneously and be brought close together, for better muscle development.

Abstract: Abstract A threaded fastener which can be installed by radial expansion into threaded engagement with a workpiece having an initially unthreaded aperture, for securing an apertured member or members to the workpiece, and which after installation can be removed in the manner of a screw or bolt, has a shank and an enlarged head.  A bore for receiving means for expanding the shank extends entirely through the shank and the head.  Within the head, the bore is enlarged by a counterbore.  At least part of the shank intermediate between its ends has an external screw thread having a sharp crest which on expansion can embed in the workpiece, and an end portrion of the shank remote from the head is unthreaded and has an external diameter smaller than that of the screw-threaded part.  The fastener is installed in an aperture in the workpiece by pulling a tapered mandrel along the bore to expand the shank and cause the screw thread to embed in the workpiece, and the head may then be deformed so as to clamp another member to the workpiece.  The mandrel may have a key-forming head of non-circular cross-section whereby the bore can be adapted to receive in keying engagement a tool of suitable shape for turning the fastener.

Abstract: ABSTRACT OF THE DISCLOSURE      A fast path (comprising control and data busses) directly connects between a storage element in a storage hierarchy and a requestor.  The fast path (FP) is in parallel with the bus path normally provided through the storage hierarchy between the requestor and the storage element controller.  The fast path may bypass intermediate levels in the storage hierarchy.  The fast path is used at least for fetch requests from the requestor, since fetch requests have been found to comprise the majority of all storage access requests. System efficiency is significantly increased by using at least one fast path in a system to decrease the peak loads on the normal path. A requestor using the fast path make each fetch request simultaneously to the fast path and to the normal path in a system controller element (SCE).  The request through the fast path gets to the storage element before the same request through the SCE, but may be ignored by the storage element if it is busy.  If accepted, the storage element can start its accessing controls sooner for a fast path request, than if the request is received from the normal path.  Every request must use SCE controlled cross-interrogate (XI) and storage protect (SP) resources.  Fast path request operation requires unique coordination among the XI and SP controls, the SCE priority controls, and by the storage element priority controls.  When the accessed data is ready to be sent by the storage element, it can be sent to the requestor faster on the fast path data bus than on the SCE data bus.  The fast path data bus may be used to transfer data for requests ignored from the fast path.

Abstract: ABSTRACT OF THE DISCLOSURE      A method and apparatus for measuring the velocity of moving particles such as red blood cells in a tissue sample is disclosed, characterized by digital processing techniques and autocorrelation.          The moving particles are illuminated to produce a spread spectrum optical signal resulting from the Doppler shift occurring when photons are scattered by the moving particles.  A spread spectrum electrical signal corresponding with the optical signal and containing spectral and noise components is generated from the optical signal.  The electrical signal is filtered to produce the bandpass and DC signals which are subsequently converted to digital form.  A first autocorrelation function is calculated from the bandpass signal and a noise autocorrelation function is calculated from the DC signal.  The first and noise autocorrelation functions are compared to produce an autocorrelation function free of a noise component.  From the autocorrelatio function, the mean frequency of the electrical signal is linearly calculated, the mean frequency corresponding with the average velocity of the moving particles.
