Title: Adaptive control system for an internal combustion engine
Inventor: HOLMES MICHAEL
IPC: F02P5/15
Filed: 1987-01-27
Abstract: An adaptive control system is provided for an internal combustion engine. The engine has a flywheel (ll) and is connected through resilient shafts (l2, l4), and gear box (l3) to vehicle wheels (l5). The flywheel (ll), shafts (l2, l4) and wheels (l5) form a resonant system which has a particular resonant frequency for each gear ratio. The control system includes two memories (35, 38) containing fixed and correction schedules for the spark advance. The values are stored as a function of engine speed and spark advance. Values are extracted by an interpolation method and added to form command values for a dwell c                          ontrol device (l7). 
<??>A perturbation generator (40) generates a square waveform at a frequency which is at least three quarters of the highest resonant frequency of the resonant system. The spark advance values are perturbed in accordance with the polarity of this waveform. A window generator (43) generates a series of positive and negative windows, each window lagging a respective half period of the square waveform by a fixed phase shift. During each positive or negative window, engine fire periods are accumulated in a respective one of two accumulators (44, 45). In a slope calculation device (46), the slope of engine output with respect to spark advance is calculated from the accumulated fire periods in the two accumulators. An updating device (47) uses the slope to make corrections to the values stored in the correction schedule. Each correction is proportional to the slope and the corrections are made by a method which is symmetrical with the interpolation method used when forming the command values.

Title: Positive displacement pump
Inventor: SIDEY ROGER CHARLES HEY
IPC: F04B49/025
Filed: 1987-02-17
Abstract: A positive displacement pump comprises two chambers adapted for alternate working to supply the pump outlet, a reservoir 11 and a control system. Each chamber incorporates a piston 3,4 in a cylinder 1,2 and is associated with upper 7,8 and lower 9,10 liquid level or piston position detectors to provide signals when the liquid levels or pistons reach the level of the detectors.

The signal from the upper detector terminates priming. The pump is capable of delivering accurate volumes of liquid under conditions of high pressure and temperature and is particularly suitable for use in apparatus for determining the permeability of core samples of rock. <IMAGE>
