Abstract: Abstract of the Disclosure A splash bar for use in fill structure of an evaporative cooling tower has an extruded body with an elongated water impingement portion operable to uniformly disperse deflected water throughout the fill structure for contact with passing air.  The splash bar body comprises a pair of arcuate in cross-section side margins and an elongated, hori-zontal,  flat top segment interconnecting the side margins.   The centers of curvature of the side margins are coincident and lie beneath the body, while the width of the flat top segment is in the range of approximately 15% to approximately 35% of the overall width of the body.  In preferred forms of the invention, the width of the flat top segment is approximately 25% of the overall width of the body.

Abstract: A B S T R A C T       AUTOMATIC STARTING DEVICE FOR AN INTERNAL COMBUSTION ENGINE IN PARTICULAR FOR THE MANUALLY STARTED ENGINE OF A POWER TOOL   Simple and reliable starting of the internal combustion engine of a power tool, for example of a chain saw (1), is achieved by means of the automatic starting device. For this purpose, automatic operation of the choke flap (15) is provided by means of the vacuum produced, on starting,  in part of the housing (5) of the power tool. To achieve this, the throttle flap (12) and the choke flap (15) arranged one behind the other in the intake channel (13) of the carburettor (3) are coupled in such a manner that the throttle flap (12) remains in a partly open position until the choke flap (15) reaches a pre-set opening angle. This produces an over-rich petrol/ air mixture on starting of the cold engine,  while,  after the engine has  started,  sufficient  air  is supplied for a short time to permit combustion of the over-rich mixture. The vacuum for operating the choke  flap  (15)  is expediently controlled  as  a function of the temperature of the power tool (Fig.2).
