Abstract: A balloon 1 comprising two sheets 2. The sheets 2 form the body 3 of the balloon 1. The sheets 2 are heat sealed together in a continuous line adjacent to the edges of the sheets 2, leaving a gap forming the neck 4 of the balloon 1. Each sheet 2 of the balloon is formed from two layers of plastic 6 and a layer of ink 7. The layers of plastic 6 are the same type of plastic, such that the sheets are formed from one type of plastic. The layer of ink 7 is printed upon the internal surface of an outer layer 8, such that the layer of ink 7 sits between the outer layer 8 and an inner layer 9.

Abstract: A computer device with a sensor subsystem for detecting off-surface objects, that carries out continued processing of the position and shape of objects detected in the vicinity of the device, associates these positions and shapes with predetermined gesture states, determines if the object is transitioning between gesture states and provides feedback based on the determined transition between the gesture states.

Abstract: An improved process is described for the separation and recovery of substantially all the propane and heavier hydrocarbon components in a hydrocarbon gaseous feedstream. In this process, the vapor stream from a deethanizer is cooled to liquefaction and contacted with a vapor phase from the hydrocarbon gaseous feedstream. The contact takes place within a direct heat exchanger, and the resulting vapor fraction, which is essentially ethane and methane, is the gaseous product of the process.
