Patent DE-4235883-A1 (DE)
Inventor: EIBL MARKUS DIPL ING
IPC: F01P7/14
Filed: 1992-10-23
Abstract: The invention relates to a cooling circuit for liquid-cooled internal combustion engines of the type generally in use in the construction of vehicles. The object of the invention is to improve the cooling circuit of the generic type taken as a basis in such a way that it is possible to match the amount of coolant and the dimensions of the air/liquid heat exchanger to the requirements of normal operation while nevertheless ensuring adequate dissipation of the engine heat at peak loads. For this purpose, a heat accumulator is arranged in the cooling circuit, this heat accumulator containing a heat storage medium between which and the cooling liquid in the cooling circuit heat exchange takes place. The heat storage medium is so chosen that it exhibits a phase transition in the upper operating temperature range of the coolant although not more than 10@C above the maximum permissible operating temperature. If the operating temperature of the coolant exceeds the temperature of the phase transition, the phase transition taking place in the heat storage medium removes a large amount of energy from the coolant and prevents a further rise in the temperature of the coolant until the phase transition is complete. In order to guarantee high energy absorption, preference will be given to heat transfer media which have a large specific heat of fusion or evaporation. <IMAGE>

Title: Frame for receiving the bridge plate of a transfer bridge
Inventor: ALTEN KURT
IPC: B65G69/28
Filed: 1993-02-24
Abstract: The invention proceeds from a frame, to be fastened to a ramp, for receiving the bridge plate in transfer bridges, the frame having an angular cross-section, and one leg being located in the ramp plane and the other leg in a plane which limits the ramp recess for receiving the transfer bridge at its top edge.

Title: Paper-making machine - has continuous elastic belt to carry web through roller gps. to prevent web damage and distortion
Inventor: STEINER KARL
IPC: D21F3/04
Filed: 1993-03-20
Abstract: The paper web is carried through the press section of a papermaking machine, or the drying or polishing stages, by at least one recirculating elastic carrier belt. At least one roller at the machine has a brake system, such as a generator. Within the loop formed by the continuous elastic carrier belt, each roller at the paper web and along its path has a slightly higher rotating speed than its preceding roller. A speed variation is effected by pressure of the delivery roller at the leading end of the drying section on transfer of the web between drying groups, against the Fourdrinier taking the web, and by pressure against the web by the take-up roller at the trailing end of the drying section against the delivery Fourdrinier. In the centre section of the drying stage, along the machine line, the Fourdriniers of two successive drying groups - of which at least one is elastic - are parallel and next to each other and travel at the same speed during web transfer. The sections which are not parallel travel at different speeds. The belt is initially stretched to carry the paper web, and then is allowed to shrink to its original length, which detaches the carried paper web. USE/ADVANTAGE - The belt is used to carry the paper web through sections of the papermaking machine where it can be subjected to stretch and/or shrinkage. The elastic structure of the belt ensures that the web is carried through smoothly without blisters, creases or shearing.

Title: Lifting platform in the bus entrance
Inventor: BECKER WERNER
IPC: B62D47/02
Filed: 1993-04-16
Abstract: There are several versions of lifting devices for wheelchairs in bus entrances. However, the majority have in part to be operated manually: to set out the rails, pivot and pull down the platform and the like. In addition, a lot of space is necessary for some of the devices and this means a loss of passenger places. The thin platform can be left lying without it being in the way. By virtue of the platform being guided on both sides, said platform can be appropriately thin and remain lying in the entrance region without it being an obstacle. It has the advantage that:   - it can be mounted in virtually every bus entrance of an appropriate width,   - it can be operated in a completely mechanical manner,   - it is always available without time needed for setting it up.   <IMAGE>
