Abstract: A boat for spillwater raft rides or similar rides having running gear includes running wheels and lateral guide wheels to accept a force exerted by a portion of the track. A safety device is provided that consists of safety wheels or runners. The latter are located above lateral guide wheels and designed to engage safety rails placed along the line to accept lifting forces.

Abstract: An amusement ride vehicle has a seat on a seat chassis. The seat moves up for assisting a physically disabled person to enter or exit the vehicle. The seat moves down before the vehicle begins to ride. A slide is attachable to the vehicle to help a disabled person get into and out of the elevated seat. The seat chassis can pivot forward to provide access to the motor which lifts and lowers the seat.

Abstract: A rail vehicle has a pivotal latch pivotally mounted to its frame so that gravity urges one end of the locking latch toward a rack extending along the railway on which the rail vehicle is positioned for movement. A smooth slideway extends parallel to and adjacent the rack and a rocker arm pivotally mounted on the locking latch has a lower end pivotally urged by gravity into contact with the slideway so that forward movement of the rail vehicle pivots the rocking arm to cause the locking latch to be pivoted upwardly out of contact with the rack with any initiation of rearward movement causing reverse pivoting of the rocker arm to lower the locking latch into engagement with the rack to prevent further reverse movement of the vehicle. Maintaining the locking latch out of contact with the rack during forward movement reduces wear and avoids the generation of clacking noise during forward movement of the vehicle.

Abstract: For the production of tin-graphite or respectively tin/lead-graphite layers, it is known to electrodeposit a tin or respectively tin/lead layer and to mechanically incorporate graphite in the boundary zone. In accordance with the method of the invention, the tin-graphite or tin/lead-graphite layer is produced electrolytically in a single operation, operating with an electroplating bath on a strongly acid basis in which graphite powder is dispersed by means of an acid-stable wetting agent, and at temperatures of up to 35.degree. C. In the respective electroplating bath the solution has a pH value equal to or less than 2 and contains in acid-stable wetting agent for graphite.
