Abstract: A natural waterfall is simulated by introducing water into an inlet box that includes a spreader for dividing the incoming stream into two laterally flowing streams that are reflected off the sidewalls of the inlet box and which collide against each other to suppress the turbulence of the incoming stream in the absence of baffle walls. The inlet box has an outlet in open communication with an outlet box through which the water flows to create the waterfall. In a second embodiment, an open-faced structure includes a back wall, side walls, and a bottom wall, and the waterfall apparatus is positioned against the back wall so that its outlet faces the open front end of the structure. Rocks are then added to fill the structure. The walls of the structure constrain the water to flow down the face of the rocks. This enables a rock waterfall to be built by inexperienced personnel.

Abstract: A display apparatus for an electronic musical instrument according to the first invention has a display section including multiple indicators provided in association with multiple tone parts, each indicator having multiple LEDs, a register section for reading out lighting time information from a memory which has lighting time information of the LEDs stored, and a counter section for performing a countdown operation in a predetermined time interval with the lighting time information in the register section as an initial value. When generation of a musical tone is instructed, the LEDs of the indicators which are associated with tone parts of the musical tone and whose quantity corresponds to volume information of the musical tone, are lit. When a count value of the counter section reaches zero, one of the LEDs is turned off or on, and the lighting time information in the register section is reset in the counter section to re-start a countdown operation.

Abstract: A rope clamp has a base and a pair of caps hingedly connected to opposite sides of the base. A longitudinally extending, rope-receiving groove is formed in each side of the base, and a similar groove is formed in each cap so that a pair of longitudinally extending, rope-receiving cylindrical bores are formed between the base and caps when the caps are closed. Upstanding spikes are positioned in each groove so that a rope in a bore is engaged by the spikes in the groove formed in the base when the caps are opened, and is further engaged by the spikes in the caps when the caps are closed. Each cap is independently hingedly mounted to the base so that one cap may be open when the other cap is closed. A catch member is secured to the base, and has teeth formed in free ends that extend in opposite directions relative to the base. Complementally formed teeth are formed in an outer surface of each cap, and these teeth engage one another when the caps are closed.

Abstract: An arthroscopic method for debulking tissue and a kit of arthroscopic tools for performing the steps of the method. A protruding piece of tissue that is bearing against a nerve is undermined by the formation of a cavity beneath it, and the cavity is collapsed by heat generated by a laser. When the cavity collapses, the protruding tissue falls into it and separates from the nerve. The kit includes plural dilator tubes that are used to progressively dilate the arthroscopic incision and plural cutter tubes that are used in sequence to cut larger and larger pieces of tissue. Plural forceps are employed to remove the cut tissue to form the cavity, and impactor members in the kit are used to compact the bone that surrounds the cavity just before the laser is introduced into the cavity to collapse it.

Abstract: A tongue and groove construction maintains the catch and latch part of a tube clamp in full registration with one another across its entire range of positions from fully open to fully closed. A groove bisects the teeth of the latch member and a complementally formed tongue bisects the catch member of the clamp. Thus, when the tongue is slidably received within the groove, the parts of the catch member that flank the tongue releasably engage the parts of the latch member that flank the groove. This maintains the tube pinching elements in full alignment with one another so that when the pinching elements are fully displaced toward one another, no liquid fluid may flow through a cannula disposed therebetween. The teeth are not provided in a second embodiment, but the tongue and groove arrangement is employed in that embodiment. The tongue engages the underside of a lip, and the clamp is either fully open or fully closed.

Abstract: The character string of a Chinese sentence is input into the memory of a personal computer, and the first six characters of the sentence are taken from that memory and placed in a main buffer. A segment processor fetches the first three of those six characters from the main buffer and puts them into a trio buffer. The segment processor then fetches the first character from the trio buffer to match with the number dictionary. This process is continued until consecutive number characters are identified. If the first character is not a number word, the segment processor uses the three characters in the trio buffer and the segmentation program and logic to search for matched name words and regular words stored in dictionaries within the hard disk memory of the computer. The identified words are treated as candidate words and are successively sent from the computer to the word buffer for further study.

Abstract: An apparatus for separating solids and liquids includes a pair of compaction chambers into each of which is inserted a fifty five gallon drum that receives the liquids and solids before they are separated. A compaction platen has a liquid-retaining wall mounted about its periphery in trailing relation to the platen, and separation of the solids and liquids is accomplished by lowering the platen into a container that has been filled with flotsam including liquids and solids. The platen has a breadth slightly less than the breadth of the container so that liquids may escape around the peripheral border of the platen as it descends into the container. The escaping liquids are collected on the trailing end of the platen by the retention wall and are carried under a vacuum or pumped to a liquid storage facility for further treatment. The platen is telescopically mounted in a housing that reciprocates between the compaction chambers so that the separation process is continuous.
