Title: Refrigeration plant of sport centre with pool and ice rink - spare capacity applied to help keep down humidity in swimming - pool hall
Inventor: WEND JOACHIM ING GRAD
IPC: F25B29/00
Filed: 1974-10-23
Abstract: The compressor of the refrigeration plant serving the ice rink delivers waste heat to the indoor swimming pool and the system maintains the humidity of the air in the swimming-pool hall at a comfortably low level. It applies more especially to winter days when (a) dry, fresh air brought in to reduce the humidity would need warming and (b) the ice rink makes reduced demands on its refrigeration system. The spare refrigerator capacity would be applied in a second evaporator circuit, parallel to the first, to cool, and so de-humidify, air withdrawn from the swimming-pool hall. The air would be sent back to the hall after re-warming, and the heat extracted from the damp air would go to the swimming-pool water. The de-humidifying would preferably be done indirectly, using glycol as thermal vehicle, so as to keep the ammonia in the refrigeration system well away from breathed air.

Title: Lift speed control system - varies speed alteration point to suit travel speed and distance to stopping point
Inventor: BLOCHER HANS-JOACHIM DIPL ING
IPC: B66B1/24
Filed: 1975-04-16
Abstract: The lift speed control system uses a braking signal generated by a stationary emitter to initiate the halting operation, the travel speed being altered in accordance with a predetermined curve. The actual value of the travel speed on the occasion of the brake signal occurring is compared with the desired value after rounding the curve representing the desired value. If it is greater than or equal to the desired value, the speed is not altered until conditions occur where the distance to be covered to the stopping point can be determined by a formula taking into account the integral of the travel speed over the time period, and the distance travelled from starting to round the desired value curve to the stopping point. Where the actual value is less, the formula determining when speed alteration is to take place takes account of the integral, the distance travelled when rounding the curve, the travel speed and the deceleration defined by the section of the desired-value curve next to the rounded portion.
