Abstract: A surface covering for games arenas such as tennis courts comprising a slab shown inverted formed of a plurality of regular polygon shaped regions (1), e.g. squares, delimited by ribs (5) which depend from the upper load bearing surface of the slab and which abut the surface to be covered and by grooves (2) in the upper surface. Further ribs (3, 4) which depend from the upper surfaces are arranged to abut the surface to be covered, and radiate from the centre of each region. The grooves (2), ribs (3, 4) and apertures 6 allow small expansions or contractions of regions (1) due to temperature differentials to be absorbed by the individual regions (1) and allow larger changes to take place substantially in the plane of the covering, thus avoiding ridges and cavities which occur with known coverings. The outer edges are supported by semi-circular 11 or quarter-circular 13 pegs. <IMAGE>

Abstract: A process for the simultaneous manufacture of pure methyl tertiary butyl ether (MTBE) and a substantially isotubene-free mixture of C4-hydrocarbons, by reacting the isobutene contained in the mixture of C4-hydrocarbons with excess methanol in the liquid phase at elevated temperatures on strongly acid, macroporous, organic ion exchange resins. The process has the following steps: (a) methanol and isobutene are reacted in a molar ratio of 2:1 to 5:1 at temperatures between 30 DEG  and 100 DEG  C.; (b) the unconverted hydrocarbons are then removed as the top product under a pressure of 2 to 10 bars from a first rectification column; (c) the bottom product from this first column is rectified in a second column under normal pressure or under a slight excess pressure of up to 2 bars at the top of the column, the bottom product of this rectification is recycled to reaction zone (a), if necessary, after separating off a portion of the tertiary butanol formed and the C8-olefins; and (d) the distillate from this second column is rectified in a third rectification column under a pressure of 5 to 30 bars, the distillate thus obtained is recycled into the feed to the second column and pure methyl tertiary butyl ether is withdrawn from the bottom of the third column.

Abstract: The attachment comprises a body with one end for acceptance in a power tool. The body has an abutment 28 which transfers axial force via a rigid spring 18, e.g. an O-ring, wave washer or coil spring, to an abutment of an external sleeve. The sleeve has a torque- limiting recess 48 of variable axial dimension biased to its longest position by the rigid spring 18. Under normal drive conditions, the rigid spring will maintain the torque-limiting recess at its maximum length position. For application of additional torque to a fastener head 38, an extraordinary axial load is applied which collapses the rigid spring and enables the operation to reengage a body polygonal bore 32 with the fastener head. The fastener- engaging surfaces presented by the tool could alternatively be in the form of a driver bit retained in the polygonal bore by set screw 14. <IMAGE>

Abstract: An incineration apparatus is provided, preferably of the thermal heat regeneration type, in which noxious or other gases are passed to an incineration chamber, to be burnt at a sufficiently high temperature that they are disposed of, and in doing so, pass through heat-exchange beds of elements such as stones or the like, whereby the direction of gas flow may optionally be reversed. The stoneware beds reside in recovery chambers adjacent but contiguous with the combustion chamber, separated therefrom by built-up refractory blockwalls. The walls are of arcuate configuration and support the heat-retention elements in the recovery chambers. The walls are generally the thickness of a single refractory block, and are of a radius that is less than any radius of the combustion chamber and are of a sufficient radius such that the forces of the stone or other heat-retention elements outside the walls may be resisted to prevent wall collapse. With this wall configuration, the combustion chamber may be of any size, however massive, and yet the walls between the combustion chamber and recovery chambers are of a sufficient arcuate configuration to provide support for the stoneware. In accordance with this invention, the walls of the combustion chamber may even be generally linear, if desired.
