    摘要: A pad retention device for a brake calliper for a disc brake for a vehicle comprises four spaced elongate cylindrical abutment pins (11) to (14) dispersed at spaced intervals around the periphery of the pad (10). The pins comprise two leading edge pins (11) and (12) and two trailing edge pins (13) and (14). Pin (13) is disposed adjacent the upper leading edge and a further pin (15) provides a centre locating and retaining pin which extends through an aperture (16) in the back plate of the pad. A cantilever spring (17) is mounted on pin (15) and pin (13). In use the spring (17) bears down on the pad (10), using pin (13) as a reaction point and centre locating and retaining pin (15) as a pivot, on the trailing edge side of the pin (15). This in turn tends to rotate the pad in an anticlockwise direction reducing or eliminating pad to abutment pin air gaps and therefore pad rattle and pad knock. This arrangement also provides improved squeal noise resistance.

    摘要: A method for preventing bacterial biofilm formation in a blood product, the method comprising modifying a blood product with a polymer selected from the group consisting of polyethylene glycol (PEG), PEG derivatives and mixtures thereof. Preventing bacterial biofilm formation in this way increases the planktonic to adherent ratio of any contaminating bacteria, and thereby facilitates detection of bacterial contamination.

    摘要: A rotor hub fairing system includes an upper hub fairing, a lower hub fairing and a shaft fairing therebetween. The rotor hub fairing system is sized and configured to reduce the overall drag on a dual, counter-rotating, coaxial rotor system. Preferably, the rotor hub fairing is fully integrated. The shaft fairing preferably includes a minimal thickness at the midsection to reduce drag with an increasing thickness adjacent the upper and lower hub fairings to reduce the flow separation on the hub fairing surfaces without overly excessive drag. Other aerodynamic structures, such as a horizontal splitter and/or a plurality of turning vanes may be mounted to the shaft fairing to facilitate flow around the upper and lower hub fairings to reduce flow separation and drag.

    摘要: A particle size distribution monitor, comprising: a transducer adapted to be a source of ultrasonic energy and positioned in contact with a suspension containing a percent by volume of particles in a liquid, the transducer transmitting ultrasonic energy through the suspension wherein the energy comprises a wideband pulse containing a range of frequency components; a transducer adapted to be a receiver of ultrasonic energy and positioned in contact with said suspension to receive said wideband range of ultrasonic energy which has passed through the suspension; a first means adapted to accept a signal from said receiver and make an instantaneous determination of the attenuation of the wideband ultrasonic energy in passing through the suspension. A method of monitoring the particle size distribution of particles in a suspension under dynamic conditions, comprising the steps of: transmitting a first pulse of ultrasonic energy containing a wideband range of frequency components through the suspension which attenuates the pulse; receiving the attenuated pulse after it has passed through the suspension; developing a first signal representative of the attenuated first pulse; digitizing the first signal with a high speed analog-to-digital converter to form a time domain signal; applying a Fourier transform to convert the time domain signal to an equivalent frequency domain signal, or spectrum, for each signal; converting the spectrum into dB to express the attenuation as a function of frequency.
