Patent GB-2155887-A (GB)
Title: Invalid hoists
Inventor: JAMES DAVID RICHARD
IPC: A61G7/10
Filed: 1984-03-16
Abstract: An invalid hoist comprises a base structure 1 in the form of a mobile chassis, an upstanding column structure 2 supported on the chassis 1 and a lifting arm 8 which projects from the column 2. The arm 8 is fixed to a traveller 10 movable along the column 2 under the control of a lifting mechanism 12 incorporating a winch drum 18 on which is wound a flexible tape connected to the traveller 10. An operating handle 27 is mounted on a spindle 15 disposed coaxially of the drum 18. Turning the handle 27 in the raising direction turns the drum 18 to wind on the tape and thus raise the traveller 10, and on release of the handle 27 the drum is braked to retain the traveller in the raised position. Turning the handle 27 in the opposite lowering direction releases the braking action to allow the traveller to fall under gravity in a controlled manner. <IMAGE>

Title: Artificial knee with improved stable link-type knee joint
Inventor: MARLOW RICHARD ZBIGNIEW
IPC: A61F2/50
Filed: 1987-01-14
Abstract: In a four bar knee mechanism for an artificial leg, resilient means such as a leaf spring (70) acts on an anterior link (10) that moves rearwardly in the latter part of travel of the mechanism from a flexed to an extended state to bias the link (10) rearwardly and assist extension of the mechanism.

Title: Adaptive control system for an internal combustion engine
Inventor: HOLMES MICHAEL
IPC: F02P5/04
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 control 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.
