Patent DE-2649611-A1 (DE)
Title: Electrode unit for removal of building dampness - has automatic DC generator supplying horizontal distributor and sloping collector electrodes in wall base
Inventor: MORARU DINU ST DIPL ING DR
IPC: E04B1/70
Filed: 1976-10-29
Abstract: The process is for removal of dampness from buildings, and for automatic prevention of recurrence of dampness. Water is prevented from rising along wall capillaries by horizontal distributor electrodes (1) in the wall (2), or at its bottom edge, and by sloping collector electrodes (3) in the base or foundations (4). These are connected to an automatic direct-current generator (5). The electric charge imposed on the wall cross-sectional surface for a distributor electrode exceeds, and has the same potential as, that for the capillary moisture. The generator automatically responds to onset of rise in capillary moisture.

Title: Multiplier circuit for video signal processing - has gated feedback circuit to multiplier transistor to increase linearity
Inventor: LEHMANN KLAUS
IPC: G06G7/163
Filed: 1976-11-25
Abstract: The multiplier circuit working on a current division principle is used for processing video signals. It contains a four quadrant multiplier with current division control, the input to be multiplied being fed to the multiplier. The multiplier consists of two pairs of emitter-coupled transistors and is fed via a logarithmic arrangement. In order to improve the circuit transfer characteristic by linearising the control inputs a controlled feedback circuit is placed between input and output of one of the transistors of the first pair. The feedback circuit is gated only during the blocking pulse. The circuit is of sufficiently wide band width for video signal processing.

Title: Vehicle brake fluid reservoir - has internal auxiliary container with float which gives fluid loss warning signal
Inventor: REINARTZ HANS-DIETER
IPC: B60T11/26
Filed: 1977-05-07

Title: Vertical window blind strip holder - has shaped access slot in strip hangers ensuring non-slip hold of blind
IPC: E06B9/36
Filed: 1977-06-29
Abstract: The vertical strips of a window blind are made of a flexible material and swivel in unison about their longitudinal axes. At the top, they have seams into which strip holders (22) can be pushed, which interact with strip hangers (13) mounted on a sliding carriage in a support rail. The free end of the strip hanger has a bearing eyelet (23) which holds the strip holder (22) and is accessible through an upwardly inclined access slot (24) which passe through one side (25). The other side (29) has a lower projection (30) which forms a stop for the parts of the strip holder, so that the holder can only be pushed in at a certain angle through the access slot into the bearing eyelet, turned into a vertical position and then pushed into the position of use. Even under the strongest strain, the blind strips cannot become detached from their hangers but the blind holders can be easily exchanged and replaced when required.

Title: Heat insulating plates comprising sheath enclosing dispersed material - densified and consolidated into plates shrunk to give pretension
Inventor: KLINGHOLZ RUDOLF DIPL ING
IPC: F16L59/02
Filed: 1977-06-30
Abstract: A finely dispersed insulating substance is filled into a sheath of flexible flat material. The filled sheath is pressed so as to densify and consolidate the insulating material into a heat insulating plate. For the sheath a flat material which alters its dimensions when heated is used, and the insulating material is continuously filled into a tube formed from the flat material. As it moves forward, the tube is divided transversely without being separated and, pressure and heat are then applied so that the tube is densified into a string of plates. Method provides insulating plates with a high degree of resistance to bending loads. The process is not intermittent but is continuous and can be fully automated.

Title: Bis:aminophenyl di:sulphide cpds. prodn. - from halo-nitrobenzene using gaseous acid anhydride to expel hydrogen sulphide for increased yield and purity
Inventor: PFISTER THEODOR DIPL CHEM DR
Filed: 1977-12-29
Abstract: Prodn. of bis-(aminophenyl) disulphides (I) involves reacting halo-nitro-benzene derivs. (II) with Na sulphide (III) and S in aq. medium and adjustment of the pH of the treatment mixt. to 4-6, (I) and (II) having the formulae: (in which R1-4 are H, lower alkyl, aryl, halogen, NO2, amino, CN, COOH or SO3H, at least one of R1-3 being halogen).
