Title: Loudspeaker device
Inventor: PFEIFFER HANS-PETER
IPC: H04S3/00
Filed: 1981-10-27
Abstract: With the invention, a loudspeaker device is described with a housing and with loudspeakers permanently installed in this housing whose sound radiation is directed partly forwards in a horizontal direction and partly backwards in a horizontal lateral direction. According to the invention, it is provided for additional loudspeakers to be installed in the housing whose sound radiation has at least one vertical component. The advantages of the invention are therefore, for example, that different horizontal and vertical sound devices of a concert hall sound field can thereby be taken into consideration and a sound field is generated which is approximately identical to that of a concert hall. The loudspeakers themselves are mostly inconspicuous as a sound source and are difficult to locate. In an advantageous embodiment, the individual loudspeakers are activated in each case via an allocated output of a microprocessor in which different sound rasters typical of a concert hall are stored, thus enabling a signal which is to be reproduced to be rendered audible according to a desired concert hall type.

Title: High-speed windsurfing board
Inventor: DUSCHEK HORST
IPC: B63B35/79
Filed: 1983-06-04
Abstract: The invention relates to a high-speed windsurfing board essentially with a ventilation shaft located on the deck, the air-intake opening (Le) of which ventilation shaft is connected via a ventilation duct (K) to an air-outlet opening (La) which comes out at the underside of the board and in front of which a separation edge (1) is attached. "Fences" (Z) extend from the air-outlet opening parallel to the longitudinal axis of the surfboard in the direction of the stern. If the surfboard moves, air is forced into the air-intake opening and under the surfboard. This action is assisted by a suction effect produced at the separation edge. The "fences" direct the air across the underside of the board and prevent the air from immediately flowing away laterally behind the air-outlet opening. On account of the air directed under the skimming surface of the surfboard, the friction resistance can be drastically reduced and a considerable increase in speed can be produced.

Title: Method for producing a low-voltage high-rupture-capacity contact clip
Inventor: JASCHKE GEORG
IPC: H01H11/04
Filed: 1983-09-28
Abstract: The invention relates to a method for producing a low-voltage high-rupture-capacity contact clip. Contact clips have been used for many years in low-voltage high-rupture-capacity fuse lower parts. However, as a result of the surrounding shape of the contact contour, costly tools are required and a large number of operations are required during manufacture. The object therefore exists of simplifying production and applying the silver facing in a metered manner, in order that only the contact surface receives the necessary minimum layer thickness. This problem is solved by means of a method in which the contact is produced from two halves (1, 2) which are in mirror-image symmetry, each contact half (1, 2) is initially coated internally (1.1, 2.1) with a silver coating, in an aqueous salt solution (3), and is subsequently provided with a silver layer internally (1.1, 2.1) and externally (2.1, 2.2). Subsequently, both contact halves (1, 2) are placed together on a busbar (5) to form a contact. <IMAGE>
