Abstract: A shower system comprising a header having a fluid inlet port, a plurality of substantially vertically aligned spray nozzles attached consecutively to said header and arranged in a substantially arcuate formation, and a drive system for laterally reciprocating said header.

Abstract: A link (10) exchanges data between a master (MC) and slave (SC) computer. Each computer has control lines (26A, 42) and incompatible information lines (26B, 26C, CA1-15, CX1-21). The master computer (MC) includes a master interface (28) connected to the information and control lines (26) of the master computer (MC). The master interface (28) has separate intercommunication lines (LA/B) and intermediate (34) lines. This master interface (28) is able to provide an intermediate signal on its intermediate lines (34) in response to signals provided by the master computer (MC) on its control lines (26A). The link (10) includes a computing subsystem (30) and a slave interface (38). The computing subsystem (30) is connected to the intercommunication (LA/B) and intermediate (34) lines of the master interface (28). The computing subsystem (30) has command lines (36) for providing thereon a command signal in response to the intermediate signal.

Abstract: A buffer can exchange data between a computer having a plurality of lines and a device. One of these lines, a halt line, can transmit a halt signal when the computer has halted. The buffer includes a plurality of transmitters and a plurality of controlled receivers. A halt transmitter is included among the plurality of transmitters. The transmitters are separately connected to predetermined respective ones of the plurality of lines for transmitting their signals to the device. The halt transmitter is connected to the halt line for transmitting the halt signal to the device. The receivers are connected between the device and given respective ones of the plurality of lines for coupling to them signals from the device. Each one of a predetermined set from the plurality of receivers has a receive terminal commonly connected to the halt line for enabling operation of this predetermined set in response to the halt signal.
