Title: Wall panel for bricks or blocks in foam slab - made in mould with compartment for each brick and steam inlets
Inventor: HAACKE WOLFGANG
IPC: E04C2/04
Filed: 1980-09-09
Abstract: An appts. for producing prefabricated wall elements composed of a number of ceramic blocks, bricks or the like embedded in a plastics foam panel by heating the plastics foam basic material around the blocks in a contg. mould is constructed as follows. The mould is subdivided into compartments, each corresponding to one brick or block, by a series of ribs fixed to the base of the mould. Each compartment contains one or more large openings in the base to permit entry of steam and each has at least 3, esp. 4 small upward projections on its base for supporting the brick or block during the moulding process. The bricks or blocks are laid in the mould, the foam material spread over them and around them, the mould is closed and high pressure steam is introduced causing the panel to be formed. A high prodn. rate by a simplified process results in very few rejects. In partic. the arrangement of at least three support points, esp. of heat-resistant polyurethane, prevents cracking of the bricks or ceramic blocks during the high pressure steam moulding.

Title: Device for recording the position of a bowling ball (disc) in order to ascertain the target position
Inventor: KOCH HEINRICH
IPC: A63D5/04
Filed: 1982-03-02
Abstract: The object of the device is to make precision measurements available fully automatically to the bowler, to increase the accuracy of decisions in competition, and to permit optimisation of training activity. The system permits the digital or analogue analysis of:     a) passage to right or left,   b) exact position of the target to right or left of the centre,   c) speed of the ball in meters/second or centimeters/second,   d) overstepping (foul shot). The system can be installed in any existing installation. Essential components according to the drawing - Figure 1 - are: two light barriers and a display panel with built-in electronics. The function of this installation is essentially determined by the beam path (S1, S2 and S2.1). The position of the target is determined from the running time on the path X1 . X2 = target position. The speed is calculated from the running time on the path (X1). Overstepping arises from exceeding the interruption period of the beam path (S1). The analysis of passage to right or left is based on the measurement of the target position. <IMAGE>

Title: Airport installations which are designed for low noise and to be environmentally friendly
Inventor: DIETRICH FRIEDRICH DIPL ING
IPC: B64F1/00
Filed: 1982-03-25
Abstract: Commercial airports restricted by irresponsible new housing developments are intended to be moved away under planning regulations. Movements away from large cities cost a large amount of money, valuable ground and land, and reduce the time advantage which makes air traffic attractive. New features:   1) Raising the ends of 800 m long runways by 2 DEG , the glide path to 4.3 DEG ; to permit an approach at low power, with little noise and damaging exhaust gases. Landing at a lower sink rate, take-off assistance by potential energy. 2) Airport buildings parallel to the runway deflecting noise by parabolic roof surfaces, the noise thus being radiated upwards. Terminal apron covered over, sound-absorbent internal cladding. New types of boxes permit rapid embarkation and disembarkation of passengers. Linked to the terminal by electric overhead railways. Environmentally friendly movements on the airfield using electric transporters. Multi-storey car-parking facilities in the airport building; small amount of land required, greater security against theft. Roads adjacent to the airport can continue to exist by tunnelling them under the raised runway ends. Ring roads which have been tunnelled over in the airport region and electric overhead railways permit rapid transportation around the entire area. s
