Title: Ventilation device, in particular a heating or air-conditioning system, for the interior of a vehicle, in particular motor vehicle
Inventor: KOUKAL HEINZ
IPC: B60H3/06
Filed: 1988-04-22
Abstract: A ventilation device, in particular a heating or air-conditioning system, for the interior of a vehicle has a fan for the exchange of air, the intake of fresh air taking place in a region which when a window-washer system is in operation is wetted with some of the washing water. The fresh-air flap contained in the air-intake stub for fresh air is moved, at the same time as the washer jets of the window-washer system are operated, into a closed position and the ventilation device is in this manner switched over to recirculating-air mode. This prevents the air from being loaded by the washing-agent concentrate and by some of the liquid from the spray jet.
Patent DE-3813900-A1 (DE)
Title: Method for humidifying supply air
Inventor: HUNKEMOELLER JOSEF
IPC: A01K1/00
Filed: 1988-04-25
Abstract: Until now, supply air has only been warmed up in air-conditioning installations for stables and buildings with a warm and moist atmosphere. The method presented here is characterised by the high humidification of the supply air for stables and buildings in which a warm and moist atmosphere prevails. In this way, less evaporation energy is to be withdrawn from the building. Furthermore, through high air humidity drying-out of the mucous membranes of the respiratory apparatus is to be prevented, in order to maintain the defence mechanisms and promote health. The humidification of the supply air is carried out in the supply-air duct of a heat exchanger by spraying water, in which process the water supply is regulated or controlled. The energy recovery here can be increased by the simultaneous heating and humidification of the supply air by about 80% in comparison with conventional heat exchangers. At temperatures below zero degrees Celsius, the supply air for humidification and heating is sprayed with water before entering the heat exchanger. In this way, the heat exchanger is protected from freezing up. The water supply is regulated here by a thermostat. The humidification of the supply air can also be carried out in a drying installation. In this case, the air circulates through a heat exchanger and through a drying installation. In the heat exchanger, the supply air is heated and in the drying installation it is humidified. A considerable formation of condensation water in the outgoing-air duct of the heat exchanger is the result of the high air humidity. ... Original abstract incomplete.

Title: Device for use in the jacking of a construction body through an earth dam or the like
IPC: E21D9/00
Filed: 1988-05-19
Abstract: In the jacking of an, in particular tubular, construction body of reinforced concrete, for example, through an earth dam or the like, the construction body is covered at the top side and if need be at the side faces by narrow, adjacent cutter strips (20) extending over its entire length in the driving direction. The cutter strips (20) are driven individually one after the other by means of separate driving jacks (23). The soil is excavated at the working face in the protection of the cutter strips (20) and then the construction body is advanced relative to the cutter strips (20). The cutter strips (20) are designed as compression members of precast reinforced-concrete parts, and the driving jacks (23) are arranged at the rear ends of the cutter strips and are supported relative to the construction body. During the jacking, the compression members sustain elastic upsetting which, after the removal of the jacking force, produces elastic breathing and thus in turn permits elastic breathing of the soil. This enables any displacements of the surrounding earth, in particular of an existing earth dam, to be prevented or completely avoided. <IMAGE>

Filed: 1988-06-14
Abstract: The invention relates to a keyless actuating system for a vehicle device, especially a door-locking device of a motor vehicle, for the wireless actuation of the latter. According to the invention, there is provided a wireless transmitter (100) which has the form of a credit card and can be carried, for example, in a shirt pocket and which, when a trigger signal is received from a control device (200) fixed to the vehicle, emits an identification signal which is picked up inductively by the control device. The control device (200), which emits a trigger signal for activating the transmitter (100), compares an identification code of the transmitter signal with a transmitter-specific predetermined identification code and, if the codes are identical, transmits a control signal to the actuating device for actuating the door lock. A special loop-aerial arrangement (214) is provided in conjunction with a manually actuable trigger switch (210) of the vehicle, in order to provide optimum transmission conditions for inductive signal coupling between the transmitter and the receiver. The invention can be used for the keyless actuation of lock systems, especially for motor vehicles. <IMAGE>

Title: Opening and delivery mechanism for folded sheets
Inventor: BOETTCHER WINFRIED
IPC: B65H3/42
Filed: 1989-04-01
Abstract: The opening and delivery mechanism for folded sheets is used in the opening and delivery of folded sheets (4) with and without a prefold on folded-sheet feeders. Its use has been proved to be advantageous and necessary, in particular in the processing of folded sheets (4) of relatively small size and at relatively high processing speed ranges. The opening and delivery mechanism is positioned on that roller of the pair of opening rollers (7, 8) which is driven in the direction of rotation opposite to that of the roller cage (3). In this case, provision is made for the folded sheet (4) moved into the pair of opening rollers (7, 8) to be picked up at its fold by means of clamping slide elements (11) positioned on the opening roller (7), as a result of which secure guiding and alignment is guaranteed by the suction and gripper elements (20, 21), which are adjustable as a function of the size, of the pair of opening rollers (7, 8) up to retention of the folded sheet (4). For this purpose, the mechanism can be adjusted to different thicknesses of the folded sheets by means of an adjusting screw, the prestress being applied by a helical spring (13). When the folded sheet (4) has been caused to open, the clamping slide elements (11) and the gripper elements (20) become disengaged under the control of a cam, and the folded sheet (4) passes to the delivery on the resting saddle (22). <IMAGE>
