Abstract: A security device can be secured to a pedal vehicle to prevent the vehicle being pedalled. The security device includes a receiving means and a securing means. The receiving means may include a through-hole means for receiving part of a frame and a pedal crank arm of the vehicle and may have an open configuration in which the frame part and a part of the crank can be placed in the through-hole means, and a closed configuration in which a frame part and crank arm are held in the through-hole means against relative movement therebetween.

Abstract: Polymer composite films were prepared by solvent casting suspensions of quantum dots (QDs) in cellulose triacetate (CTA) solution. The films were robust and possessed the optical properties characteristic of QDs. Transmission electron microscopy (TEM) images of the films revealed that the QDs were well dispersed within the CTA film matrix. The selective alkaline hydrolysis of QD/CTA films in 0.1N NaOH over 24 hours resulted in the surface conversion of CTA to regenerated cellulose. Optical properties of the films were probed both before and after the hydrolysis reaction using fluorescence spectroscopy, and were found generally unaltered. The cellulose surfaces of the alkaline treated films allow for facile incorporation of the films into paper sheets.

Abstract: A method of determining the lift generated by a lift-generating member is presented. The lift-generating member being coupled to a component within the lift load path with the lift load path component experiencing strain as a result of the lift generated by the lift-generating member. The method involves the steps of coupling at least one strain measurement means to the lift load path component, obtaining strain measurements from the strain measurement means, and calculating the lift generated by the lift-generating member from strain measurements.

Abstract: A method for reducing lace breakage in a process in which a continuous roving is impregnated with a polymer powder before melting and consolidating the impregnated roving, wherein the consolidated lace tension is continuously recorded and the supply of polymer to the roving correspondingly adjusted.
