Abstract: A method indexed indirect addressing is provided with matched pairs of prefix bytes (PR) and suffix values (IM1, IM2) which can surround any instruction. The method consists in fetching a prefix code (PR) in the instruction stream, fetching a word in main memory at an address specified by the contents of an index register modified in accordance with a suffix value (IM0), and interpreting this word as an address to be modified by a suffix value (IM1) if a prefix code (PR) has been detected. These steps are repeated for each prefix code (PR) detected in the instruction stream.

Abstract: A processor (20) for processing undeveloped photographic film discs (30) mounted on a spindle assebly (31) has a conveyor (52, 54, 62, 64) to intermittently convey the spindle assembly (31) along a generally horizontal conveyor path. The spindle assembly (31) is conveyed to a plurality of processing stations (60a-60h, 61a-61h) on the conveyor path, with each processing station having a processing tank (100-114). During processing, the processing tanks (100-114) pivot between an upward process position and a downward dump/transport position. In their upward process position, selected processing tanks are filled with processing fluids. When the spindle assembly (31) is positioned at one of the selected processing tanks (100-114) and that tank is in its upward process position and filled with processing fluid, portions of the film discs (30) on the spindle assembly (31) are contacted by the processing fluid. The spindle (31) and discs (30) are then rotated to uniformly contact the photographic images on the film discs (30) with the processing solution. While the conveyor (52, 54, 62, 64) advances the spindle assembly (31) to a next processing station, the processing tanks (100-114) are pivoted to their downward dump/transport position and the processing fluid is dumped from the selected processing tanks.

IPC: A61B5/028
Filed: 1984-04-12
Abstract: Flow, and in particular nonuniform flow, as in a vascular system, is measured by applying a stochastic excitation signal to a system inlet which results in a measurable output signal at a downstream system outlet. Flow rate may be extracted by cross-correlating the excitation signal and the output signal. Calibration may be effected by conservation of mass principles whereby quantity type parameters are related to concentration type parameters. The stochastic signal has the characteristics of white noise, such that simplified spread spectral detection and signal extraction techniques may be employed to recover the desired intelligence.

Abstract: A slot machine has a game number counter which cumulatively counts the number of games played. That the number of games counted by the game number counter reaches a preset number or not is compared by a comparator, and if both numbers coincide, a coincidence signal is output from the comparator. The slot machine has also a winning number counter which cumulatively counts the number of winnings generated during the period until the number of games reaches the preset number. At the time the coincidence signal is obtained, the number of winnings cumulatively counted in the winning number counter is compared with a standard number of winnings. As a result of the comparison, if the number of winnings in the winning number counter is larger than the standard number of winnings, the following game is set difficult to get a winning, and in the contrary case to the above, control means is actuated for controlling a shift of symbols onto a winning line.
