摘要： A cleaning apparatus for microsurgical instruments has a flush chamber closed off at one end by a first plug adapted to liquid-tightly grip one end of the instrument, allowing a portion of the instrument to extend past the first plug and out of the flush chamber. The other end of the flush chamber is closed off by a second plug having an inlet port. Liquid injected through the inlet port on the second plug passes through an internal passageway formed in the instrument and exits the instrument through the portion that extends past the first plug. In another embodiment the instrument has an internal passageway and an end cap through which flushing ports are formed which communicate with the passageway. A first plug having an inlet port is liquid-tightly attached to the end cap and liquid injected into the first plug passes through the plug, through the flushing ports and through the passageway to clean detritus from the instrument.

摘要： There are proposed wireless headphones which have at least one electroacoustic transducer for the reproduction of audio signals, a receiver for receiving wirelessly transmitted audio data, an intermediate memory for putting the received audio data into intermediate storage, an audio decoding unit and a control unit. The audio data wirelessly received by the receiver are firstly buffered or put into intermediate storage in the intermediate memory. The control unit controls reading of the compressed audio data stored in the intermediate memory so that said data are passed to the audio decoding unit where the compressed audio data are decoded and then outputted by means of the electroacoustic transducers. Wireless transmission is effected at a higher speed than the reproduction of the stored audio signals.

摘要： An intelligent vending system such as a pay telephone provides local/remote diagnostics, fraud prevention, capability of facilitating local coin overtime operation, complete cash box accounting, and detailed reporting. Information regarding each transaction is recorded and is useful in verification, by way of example. The system includes a delta-sigma driver for reducing circuit complexity and improving circuit reliability, and a one-wire, high speed communication controller which facilitates high speed downloading and uploading of data, records, and operating program code. Battery management techniques, memory management, and coin detection circuits add to the system's capabilities and reliability. Firmware security techniques and operating system formats also promote product firmware security and configuration control.

摘要： An automatically operating apparatus is disclosed for applying webs of rubber or similar lining material of predetermined width and length to expanded surfaces of walls of steel in vessels, reactors of apparatuses and for pressing said webs thereagainst, with said apparatus comprising a guide frame for a drivable carriage and with said guide frame being easily mountable to follow surfaces of different lengths. Mounted on said carriage is an unwinding means for the web material as well as drivable position and pressing head adapted to be moved in the longitudinal direction of said carriage. The assembly is such that during operation, said pressing head is caused to steadily move along a zig-zag path and, in the course of unrolling said web material from the supply reel, said head positions said web portion against the surface to be lined progressively from left to right and from right to left and presses said web portion thereagainst at a constant predetermined pressure. By means of devices mounted on said carriage, application of the webs is accomplished simultaneously with the formation of a seam overlapping with the previously applied web and finishing treatment of this overlap seam and the preparation of the next overlap seam, which means obliquely cutting the open longitudinal edge of the web.

摘要： A cleaning apparatus for microsurgical instruments of the type having screw-type mechanisms used to advance or retract a plunger has a hollow sleeve into which the injector is liquid-tightly inserted, the sleeve being configured to hold the plunger in a fixed position when the plunger is disengaged from the injector body. A cap having an inlet port is liquid-tightly attached to the sleeve and cleaning liquid is forced from a syringe into and through the inlet port, flushing detritus from the injector. Various sizes and shapes of sleeves are used to accommodate different injectors.
