Patent DE-3203338-A1 (DE)
Title: Miniature building, especially as a model railway accessory
Inventor: VOLLMER WOLFRAM
IPC: A63H33/04
Filed: 1982-02-02
Abstract: The invention relates to a miniature building, especially as a model railway accessory. Miniaturised buildings are conventionally capable of individual assembly and are therefore provided with windows, balconies and/or doors on all vertical faces. If it is desired to combine such buildings to form a block, it is impossible to place them adjacent to one another without a gap. These problems are eliminated by means of the invention, in that the vertical faces of the buildings which are to face each other are each provided with a masking body (12), each of which possesses a wall part situated at a distance from the vertical face of the building and masking the latter, and having a connecting surface (14) on its outside. It is thus possible to attach to vertical faces of buildings wall parts which rest with virtually no gap against the surfaces of the vertical faces or can be fixedly connected thereto. <IMAGE>

Title: Safety lock
Inventor: FRANKE HORST PROF
IPC: E05B47/06
Filed: 1982-06-08
Abstract: A safety lock, especially a lock for a customer safe-deposit box, is equipped with one or more tumblers actuated by means of a customer key, with a slide and with a magnetisable locking lever which is fastened pivotably to a lock bolt. The locking lever is pivotable by means of a magnet which can be excited electrically by the bank and is arranged in the closing strip and which is located in the pivoting range of the locking lever. In the shut-off state, the magnet is located above the bolt nose of the lock bolt and has two coil windings, one winding serving for activating the magnet and the other winding for transmitting a signal representing the lock position. By means of a horizontal pin in the lock bolt, the locking lever is connected vertically pivotably to the latter and, at the rear end facing away from the magnet, via an articulated connection member to at least one tumbler. The locking lever is brought nearer to the magnet into the magnetic range of the latter during the rotation of the customer key.

Patent DE-3233014-A1 (DE)
Title: Structural element for erecting dry masonry
Inventor: AUGUSTIN LOTHAR
IPC: E02D29/02
Filed: 1982-09-06
Abstract: The invention relates to a structural element which serves to erect dry masonry. In known structural elements of this type there is no mutual keying, so that the erected dry wall can at least partly give way to the pressure of the earth piled up behind the wall. The invention specifies a structural element which not only prevents displacement of the erected dry wall by the earth pressure but also enables an aesthetically pleasing structure to be established. This is achieved by the structural element being formed as a regular polygon with an even number of sides and being provided with recesses at every second side of the polygon. <IMAGE>

Title: Depletion-type field-effect transistor and method of producing it
Inventor: HORNINGER KARLHEINZ DR
IPC: H01L29/78
Filed: 1982-09-27
Abstract: The invention relates to a depletion-type field-effect transistor on a semiconductor body. As high a channel resistance as possible is required to permit its use as a load element. According to the invention, this is achieved in a simple way in that the channel region is longitudinally divided in the source-drain direction so that at least a first subregion (9a, 9b) is present which has a conduction type opposite to the conduction type of the semiconductor body (1) and, next to it, a second subregion (9c) which is of the same conduction type as the semiconductor body (1). The field of application comprises flip-flop circuit load elements, in particular in semiconductor memories.

Title: Process for the preparation of 4-chlorobenzenesulphonyl chloride
Inventor: YAMAGUCHI AKIHIRO
IPC: B01J27/08
Filed: 1983-02-25
Abstract: Process for the preparation of 4-chlorobenzenesulphonyl chloride in which chlorobenzene is reacted with chlorosulphonic acid in a halogenated aliphatic hydrocarbon in the presence of an alkali metal salt of a mineral acid and/or an ammonium salt of a mineral acid. After washing the resulting reaction mixture with water and separating off the halogenated aliphatic hydrocarbon layer, water is distilled off together with the halogenated aliphatic hydrocarbon in order to obtain 4-chlorobenzenesulphonyl chloride in anhydrous form. The anhydrous 4-chlorobenzenesulphonyl chloride thus obtained can be converted into 4,4'-dichlorodiphenyl sulphone by reaction with chlorobenzene in the presence of a catalytic amount of iron(III) chloride.

Title: Blind as thermal-insulation and noise-insulation device
Inventor: OHLINGER MANFRED D DR
IPC: E06B9/386
Filed: 1983-03-10
Abstract: A blind in front of the outside wall of a building acts as thermal insulation and noise insulation as the heat exchange between building and surroundings is made more difficult and the sound waves from noise sources outside the building are damped. If, instead of the conventional opaque blind, a blind is used, the essential components of which are transparent, an additional thermal insulation and noise insulation can be achieved with such closed blinds even during the day, the rooms lying behind not being restricted in their use. By means of textured surfaces, it is avoided that the rooms behind the transparent blind can be seen into from outside.
