Title: Apparatus and method for displaying aircraft flight path angle on an attitude display indicator
IPC: G01C23/00
Filed: 1989-07-25
Abstract: A flight path angle symbol is positioned on an 
aircraft attitude display indicator as a function of 
either a measured flight path angle or a flight path angle 
commanded by the pilot. When the aircraft is operating 
within a selected airspeed, angle of attack, pitch 
attitude or load factor range, or the difference between 
measured flight path angle and commanded flight path angle 
is within a selected range, the symbol is positioned on 
the display as a function of commanded flight path angle. 
However when the aircraft is operating outside any of 
these ranges, the symbol is positioned on the display as a 
function of the measured flight path angle. To avoid a 
rapid jump in symbol position when transitioning between 
measured and commanded flight path angle displays, a phase 
lag filter is used to attenuate and lag the symbol 
positioning signal.

IPC: B29B9/06
Filed: 1989-06-14
Abstract: Apparatus for use in producing pellets comprises 
a pelletizer comprising an annular chamber 29 
partially defined by a pellet plate 25 against which 
spring loaded knives are urged. Pellets produced by 
moving the knives relative to the plate to repeatedly 
cut plastics extruded through apertures in the plate 
25 are carried by a water stream out of the chamber. 
This stream enters the chamber via an inlet 40 and 
performs one cycle round the chamber before exiting 
the chamber with the pellets via exit 2 which is in the 
same plane as inlet 40. With this arrangement the 
axial extent of the pelletizer is reduced and the 
relatively short travel of the pellets promotes 
effeciency.
