Title: Mechanical damper for lowering a toilet seat and/or toilet lid
Inventor: WOJCIECHOWSKI WITOLD
IPC: A47K13/10
Filed: 1987-06-04
Abstract: The damper, produced from plastics or non-corrosive material, serves to secure the WC elements against free, uncontrolled falling, which may be dangerous for children and is noisy. The pivoting movement of the falling WC elements, which are fixed to the bolts of the damper, is converted into a thrust movement of the so-called pushers, which exert a pressure on the springs. The mechanical energy produced as the WC elements fall is stored by the springs.
Patent DE-3722605-A1 (DE)
Title: Charge-air cooler (intercooler) for combustion (heat) engines
Inventor: ENGLER GUSTAV DIPL ING
IPC: F28F9/00
Filed: 1987-07-09
Abstract: The temperature differences occurring in the case of charge-air coolers for combustion engines between the side parts onto which the hot charge air flows and the tubes through which water flows lead to different thermal expansions which can lead to damage to the finned (gilled) tube block. In order to reduce these thermal expansions, the side parts are constructed from wall parts which can be displaced with respect to one another parallel to the axes of the tubes. Stresses caused by thermal expansions can therefore not occur. The charge-air cooler is used to cool the air for a combustion engine. <IMAGE>

Title: New type of car seats for passenger cars - storage systems - car first aid kit and the like
Inventor: KRIPP HERBERT
IPC: B60R7/04
Filed: 1987-08-12
Abstract: The present invention includes the entire collection of seats, their novel design and the creation of storage systems in passenger cars and other motor vehicles. By redesigning the front group of seats and their height in passenger cars there could be provided receiving systems integrated under the seats for the novel emergency technology - the car first aid kit/emergency radio. Moreover, an accident-proof holding bracket for retrofitting new and used vehicles with the car first aid kit which is installed from left to right on the front seat linkage has been developed. The redesigning of the rear seat-bench base in new designs of passenger cars, a closable sliding compartment being integrated underneath both on the left and the right. Further redesigning of the back parts of the two front seats, so that they are configured similarly to cupboards with sliding closing devices, could likewise open up further storage systems. Another variant - to design the whole of the car seats (back seat surfaces) so that they are accident-proof and removable and to provide nice matching covers for these - is forward-looking.

Title: Flapping-wing aircraft having struts and ribs made of a material whose modulus of elasticity reduces in the longitudinal direction
Inventor: SANDROCK HEINRICH
IPC: B64C33/00
Filed: 1987-09-17
Abstract: The fibre content of the composite material is varied such that the modulus of elasticity of the struts and ribs reduces in the longitudinal direction. In the case of the intended structure having an undercarriage, the wings are caused to oscillate by operating the foot-operated crank. At the same time, the wing ends deform such that forward propulsion is produced and the aircraft lifts off at the minimum flying speed. The pilot can take off without external assistance. Flight is accelerated and a change made into climbing flight by further oscillation of the wings. In areas of upward air currents, the wings can be stopped, so that the aircraft glides. Any desired destination can thus be reached, independently of zones of upward air currents. It will be an ideal recreational appliance, which can be used for terrain searching as well. <IMAGE>

Title: Side wall of a freight container
Inventor: DOERPMUND WILLI DIPL ING
IPC: B62D33/04
Filed: 1988-10-20
Abstract: The side walls of relatively large piece goods containers of standard dimensions have previously been made using strip material of sheet metal whose width deviates from standard widths in order to have the width of the strip material available for the height of the side wall and to be able to unwind and cut off the length of strip material required for the length of the side wall from a coil on which the strip material is wound. According to the invention, strip material is now used which has a standard width, the sections of strip material to be unwound and cut off from the coil having a length which corresponds to the height of the side wall. A plurality of such sections are rigidly connected to one another successively in the longitudinal direction of the side wall, the selected standard width of the sections of strip material, multiplied by the number of sections, resulting in the length of the side wall with the least possible deviation in order to be able to keep the required blank, restricted to one of the sections of strip material, as small as possible.
