Title: Method and apparatus for inferring barometric pressure surrounding an internal combustion engine
Inventor: CULLEN MICHAEL J
IPC: F02D41/04
Filed: 1991-07-29
Abstract: Abstract of the Disclosure A mass airflow based control system for an internal combustion engine is provided which is capable of inferring barometric pressure surrounding the engine.  The control system determines the air charge going into the engine from a measured value of mass airflow, and compares this value with a predicted value of air charge going into the engine, which the control system infers.  Differences between the two values are first attributed to inlet air temperature, which is measured, and then to a change in barometric pressure, which is the inferred barometric pressure.

IPC: C08F265/06
Filed: 1991-06-24
Abstract: A monomer-rich acrylic syrup is cast including about 10% to about 20% ground acrylic particles. During curing, the particles absorb over half their weight in monomer, and a cured sheet is formed in which the matrix monomer and uncrosslinked polymer form a phase which extends through the particles, while the particles appear to be fused together. Including a crosslinker in the syrup further insures the interpenetration of the matrix phase into the swollen particles. A textured surface is formed, which is useful as an anti-slip surface in bathtubs and shower stalls, after thermoforming.

The outer end of the outer boom section swings rearwardly about the pivot axis upon contact with a foreign object.  After passing the object, the outer boom section automatically returns to  its  original position.  The outer boom section is capable of being folded to a position parallel to the inner boom section. A stop lug is located on one part of the hinge opposite a slot on the other part of the hinge.  A movable plate is located on the same part of the hinge as the slot and is attached at a point above the slot such that the force of gravity causes the plate to cover the slot to cause the folding of the boom to be stopped at an intermediate position by contact between the stop lug and the plate.  The plate can be moved to expose the slot and permit the lug to pass through the slot so the outer boom section can be moved to a position parallel to the inner boom section.
