  • Patent number: 6484490
    Abstract: A gas booster system in which a variable frequency drive is used to control, by means of a variable speed motor, the compression rate of a pump in a gas turbine combustion engine. The rate of the variable speed motor, and thus the rate of compression, is controlled by monitoring turbine temperature. The gas turbine system responds to the turbine temperature to regulate the rate of compression of the fuel.

  • Patent number: 5076427
    Abstract: A tape (10) for storage of electronic flatpacks (18) has pockets (12) each of which has a floor (12A) inwardly deformed to define a protrusion (14) which is square in outline. The protrusion (14) defines a support surface (14A) disposed at a first clearance (X) from the pocket floor (12A) and a ridge (14B) which extends along the outer peripheral boundary of the support surface (14A), the top of the ridge (14B) being disposed at a second clearance (Y) from the pocket floor (12A) and by a third clearance (Z) from the walls (16) of the pocket (12). An electronic flatpack (18) having a body (19) and protruding cranked connector pins (20) is carried by the support surface (14A), the pins (20) being disposed over the ridge (14B) and in the third clearance (Z). When the flatpack (18) is lifted from the pocket (12), clearances (X) and (Z) prevent the pins (20) from being damaged by coming into contact with the walls (16) or floor of the pocket.
