Patent CA-2089278-C (CA)
Title: Gas turbine engine cooling system
Inventor: COFFINBERRY GEORGE ALBERT
IPC: F02C7/18
Filed: 1993-02-11
Granted: 2002-05-28
Abstract: A gas turbine engine cooling system. A first turbocompressor and a heat exchanger are fluidly interconnected and are each in fluid communication to receive air of differing pressures and temperatures.      Typically, such air is received from various regions of the engine low pressure compressor and the engine high pressure compressor. The system delivers air through a duct to a portion of the engine for cooling, such as the engine high pressure turbine region, at lower temperatures and higher pressures than if cooling air were directly dusted from the engine compressor to the engine turbine.

Abstract: Method of determining the stroke volume of the human heart from the pulse-type blood-stream pressure signal derived from the aorta and consisting in each case of a systolic and a diastolic period. Said method comprises calculating the flow q(t) from the pressure p(t) and integrating the flow over the systolic period, the aorta being regarded as a transmission line supple-mented with a windkessel compliance and the pressure/volume relationship in the aorta as an arctangent relationship. The pres-sure represented by the pressure signal - for each stroke prior to the calculation of the flow - is linearised by means of the arctan-gent relationship, for fixed aorta length, of the aorta pressure cross section, the values, associated with the final diastolic pressure, of the characteristic impedance of the transmission line and windkessel compliance being adhered to or is used without modification. The characteristic impedance of the transmission line and the windkessel compliance are continuously adapted to the pressure of the windkessel compliance for each stroke concerned.  Additionally, to calculate the flow, the flow through the pe-ripheral resistance is added.

Abstract: An override device is proposed to permit the manual operation of a closure which is normally driven by an electric motor. The override device comprises a manual closure driving mechanism, such as a chain engaged around a pulley, which when operated first produces the translation of a first gear along its rotation axis until this first gear meshes with a second gear connected to the output shaft of the motor which normally drives the closure. During the translation of the first gear, a switch is tripped to safely interrupt power to the motor and a mechanism is operated to disengage the motor from the output shaft. Thereafter, further operation of the chain, and therefore further rotation of the pulley, is adapted to cause the first gear to rotate instead of translating, whereby the second gear is driven into rotation by the first gear thereby causing the rotation of the output shaft and the manual operation of the closure. More particularly, the first gear is prevented from rotating with a cam mechanism associated with the pulley causing the translation of the first gear and, once the first and second gears become so engaged, the first gear can rotate with the pulley.

Abstract: A vehicle windshield bug and debris deflector mounted on a rearwardly extending flange portion underlying the front portion of a vehicle hood is disclosed. The deflector, extending substantially the full width of the vehicle hood, comprises a shield having a linear portion, a sharply curved portion, and an upstanding bug deflection portion, at least one attachment strip and at least one resiliently deformable stabilizer. The attachment strip, having adhesive on bothtop and bottom surfaces, attaches the upper surface of the linear portion of theshield to the rearwardly extending flange portion underlying the front portion of the vehicle hood. The stabilizer, having adhesive on one surface, attaches to the lower surface of the linear portion of the shield. When the hood is closed, the stabilizer is compressed between the lower surface of the linear portion of the shield and an upper surface of the vehicle grille, thereby reinforcing the attachment of the upper surface of the linear portion of the shield to the attachment strip and the attachment of the attachment strip to the rearwardly extending flange portion underlying the front portion of the vehicle hood.

Title: Hydrogen peroxide-based compositions and their use as fixatives for perms
Inventor: SAMAIN HENRI
IPC: A61K8/00

Abstract: A more rapid charging of an integrating capacitor of a PLL is provided when large frequency changes are desired. In one embodiment, the phase locked loop (PLL) circuit sinks or sources current to charge or discharge the integrating capacitor. A threshold voltage proportional to a current through the capacitor turns on a circuit which sinks or sources more current of the proper polarity to the integrating capacitor from an external source until a PLL lock is achieved. Once the lock is achieved, if a small correction current is required by the PLL, the small correction current is below a threshold required to actuate the augmenting circuit, and the PLL loop behaves in the usual manner as if the augmenting circuit were not present. In another embodiment, the integrating capacitor is reduced in value by switchably connecting a second capacitor in series with the integrating capacitor so that the total reduced capacitance of reduced value can be charged more quickly.

Title: Parachute ground disconnecting devices
Inventor: HOGAN JAMES V
IPC: B64D17/38
Filed: 1995-08-29
Granted: 1999-12-07
Abstract: Reusable  parachute  ground  disconnecting devices provide constant release load percentages within a range of 25 to 70 percent of the load weight for more reliable  delatching  characteristics  on  ground  contact even  in the  presence  of  high ground winds,  and with virtually no risk of premature delatching occurring while airborne.  Non-linear main springs consisting of stacked disk springs provide ever diminishing deflection to the load suspending assembly as the load size increases, in combination with fixed latch geometry produce constant load  release  characteristics  for  the  entire  capacity rating for a given device.   Various time delay means, including  an  hydraulic  dampened  load  release  timer provide added safety and reliability by  isolating the delatching system when fluctuations in load weight occur during  initial  deployment.     Disclosed  concepts  are readily adaptable to high capacity devices for loads of up to 30 tons, and even more.
