Abstract: The present invention relates to acousto-optic applications of parametric optical apparatuses that use the mechanical energy of elastic oscillations to convert light over a wide range of wavelengths and amplitudes and to generate coherent light.

Abstract: A pair of nested handbags which can also function as independent units. The inner handbag can be secured to any one of a plurality of outer handbags having different colors and styles. The method of securing the handbags to each other is through a simple mechanism of flexible straps and snaps that can also serve to hold carrying handles.

Abstract: A computing system for effecting scientific and technical calculations comprises at least a group of processor modules (1-1 . . . 1-N), a switch (2), an auxiliary switch (3), a group of associative memory modules (4-1 . . . 4-N), a buffering block (5). The computing system provides information processing without any inter-processor exchange, hence, decreasing the time for program processing.

Abstract: The invention introduces applications of the use of coherent and non-coherent light in the high wavelengths of the visible spectrum and in the near wavelengths of the infrared spectrum. The applications include a system for the identification of objects under varying light conditions, a system to determine the distance to and size of objects under observation, and a movement sensor system to detect a significant change of position of objects under observation.

Abstract: The invention relates to computer science, in particular, to computer systems using data flow control over computations and to the further inclusion of processing means utilizing the von Neumann principle of computation resulting in an improvement of performance and a decrease in the volume (size) of associative memory.

Abstract: A Body Access System for the collection of samples and the administration of fluids comprising means to prevent complete withdrawal of a needle stylet, means to dispose of needles and needle stylets provides for limited exposure to samples collected, needle sticks and stylet sticks.

Abstract: A knife has a locking arm with a laterally displacing spring bias that retains the locking arm in a notch on the blade of the knife when the knife is in the open position. A lateral displacement of the locking arm is required to close the knife.

Abstract: The invention relates to computer science, in particular, to a computer system comprising a processor, an input-output switch, an instruction loading switch, instruction memory, and a data access unit which uses the dataflow principle of computation. Performance is increased by decreasing the volume of associative memory by means of the introduction of the use of a fragment routine processor to process segments of the program which are better processed by von Neumann principles of computation.

Abstract: A variable pitch musical drum comprising at least one drumhead the pitch of which can be varied while the drum is being played by varying the volume of air inside the drum, by varying the rate of air flow into or out of the drum, or by a combination of these two principles.

Abstract: A process for the production of calcium borate from boric acid; boric acid, obtained from any source, is reacted with a calcium compound, preferably calcium hydroxide, in an aqueous medium to obtain a suspension of solid calcium borate which is then separated from the residual liquor. Preferably the boric acid is prepared from minerals containing borate salts, in particular, colemanite and howlite; wherein said minerals are ground, reacted with sulfuric acid in an aqueous medium, at high temperature, to obtain a pulp of solids, including mainly gypsum and clay, in a liquor; said solids are eliminated from the liquor and boric acid is crystallized.

Abstract: A Spinal Fluid Collection System comprising means to prevent complete withdrawal of a needle stylet, means to dispose of needles and needle stylets and means to collect fluid samples provides for limited exposure to spinal fluid samples and to needle sticks from spinal tap needles and stylets during and after the performance of a spinal tap.

Abstract: Contention free switches, networks and global interconnection systems for routing messages from N input sources to M output destinations are disclosed.

Abstract: A system for the remote identification of objects under varying light conditions. Objects are illuminated with a non-coherent light source for viewing by an observer. A low power laser diode and lens system which sends a laser beam out on an inclined plane determines the distance to and size of objects under observation. A significant change of position of objects under observation causes an alarm to be activated.

Abstract: A folding wheelbarrow which is durable and also easy to store. The legs fold up against the frame and the wheel is suspended below the frame. This construction allows the topside of the frame to rest flush against a wall for storage.

Abstract: A common complication of vaginal delivery is the tearing of the muscles of the vagina and perineum. This tearing results in an irregular laceration which the surgeon must then repair. Current obstetrical practice is to prevent this irregular laceration by performing an episiotomy to create a regular laceration which is later sutured. However, both natural tearing of the vaginal and perineal muscles during delivery and surgical episiotomies are subject to further, more grave, complications. The use of medical therapy instead of surgical therapy will reduce the incidence of lacerations of the muscles of the vagina and perineum. The use of medical therapy for the relaxation of the muscles of the vagina and perineum is described.
