Abstract: A method of producing protein stabilised emulsions comprising the steps of decreasing the pH of a protein solution by the addition of an acidic solution to convert it to a cationic form, heating the solution until the protein is solubilised, and then adding a lipid. The lipid is typically any fractionated or partially purified protein but may also comprise a mixture of proteins. The protein must be in a cationic form. There is also provided an oil in water emulsion and water in oil in water emulsion, made by the method.

Abstract: A conventional motorcycle modified by a center lever steering control that is slidable in longitudinal extension and rotatable about the axis of slide at the extremities of slide but not therebetween, and is pivotable vertically around a pivotal connection to a center steering unit in place of conventional handlebars. Handlebar controls are attached for foot control. Resilient knee rolls are fixed to a gas tank above the knees of a rider to prevent slipping from motorcycle when rising from seating position to strike a ball. An upwardly extending hand loop fixed above a gas tank and knee rolls ensures that leaning outwardly does not change direction of travel by inadvertent movement of the steering control. Wider tires than in road riding and disc wheels are respectively recommended for improved traction and the abolition of chance of catching a mallet in a spoked wheel.
