摘要： A tyre sealant formulation which demonstrates ideal properties for use in high speed vehicles is achieved by balancing the viscosity properties with ideal density. The required properties for slow moving vehicles involve a different balance of viscosity and density. Application of the invention described allows optimisation of formulations to give improved performance under the extremely differing conditions met by these vehicle types. The formulations also provide for the protection of the tyre and wheel components from corrosion and the freeze and excessive heat resistance required.

摘要： Apparatus comprises a Board (3) with a segmented track (7), Simulated Keyboard (2) and Symbol Flap Board (1). Each area of track is marked with a music script symbol or an instruction. A player whose moving piece lands on a particular track area must define symbol and check accuracy by lifting the corresponding Symbol Flap on Symbol Flap Board, or obey instruction shown which may be to miss a number of turns corresponding to beats represented by a music 'rest' symbol or pick a card from a pack. Each card is marked with a different music script note, and the player must lift the key of the Simulated Keyboard he believes matches the script note. As a check the true script note is exposed when simulated key is raised. Players are rewarded for correctness in defining symbols and identifying notes depicted on the various cards by receiving counters with the object of winning over their opponents. A dice used in the game may bear musical indicia (Fig. 3).
