Patent DE-2923156-A1 (DE)
Inventor: BRAJDER ANTONIO DIPL ING
IPC: G08C19/02
Filed: 1979-06-07
Abstract: A signalling apparatus has at least one transmitter in a transmitter assembly for transmitting a signal by impressed current to several spatially separated receivers. A series circuit of threshold members is connected to the output terminals of each transmitter, the number of members corresponding to the number of receivers. The input of each receiver is connected to a threshold member; the receivers are therefore connected in series on the input side. It is ensured thereby that the same current flows through all receivers. In the event of a failure of a transmission line or a receiver, the current continues to flow through the associated threshold member so that signal transmission to the other receivers continues uninterrupted.

Title: Wood impregnating bandage - with plastic fibre mat carrying preservative fixed to cold curing plastic
Inventor: SCHAWE HANS-HEINRICH
IPC: B27K3/14
Filed: 1979-06-28
Abstract: The parts of wooden masts and piles standing in soil are protected against rot by a flexible bandage consisting of impregnating agents and plastic preservative carriers on an elastic substrate, made of bituminised glass or polyester fibre mat. The coating is applied to the substrate in a way which creates separate fields, divided by impregnation-free channels of irregular shape in which condensate can collect. The preservative can be fixed to an aq. dispersion of polyvinyl acetate (50 pts. wt.). This increases the active surface area and achieves an accelerated formation of new crystals even when the wood of the masts is dry.

Title: Measurement of relative displacement between two mining bodies - using rotating sensor on one detecting markers on another
Inventor: MEHNERT WALTER DIPL ING DR ING
IPC: G01D5/36
Filed: 1980-05-14
Abstract: The method is for measuring a length traversed by two bodies moving linearly w.r.t. each other and involves measuring the passage of markers on a carrier attached to one body using a sensor arrangement attached to the other. The arrangement produces high accuracy, high resolution measurement results and is simple and economical to make. The sensor rotates about a shaft attached to the other body so as to measure the time interval at one end of the measurement path between a reference signal corresp. to a defined sensor angular position and the measurement sensor signal. This time interval is associated with a marker having a definite known distance from the other end point of the measurement path. The distance of the measurement normal from the identification mark is computed from the defined angular position, the measured time interval, and the sensor rotation speed.

Title: Permanently-mounted cable reel for electrical appliance - allows drum to turn about two axes preventing twist in fixed cable end
Inventor: NAPIERSKI REINHARD
IPC: H02G11/02
Filed: 1980-06-27
Abstract: The cable drum is typically for use in industrial or domestic installations. The operating principle can be extended to include hoses or ropes. The drums assembly is suitable mounted on a wall or ceiling, and the supply end of the cable attached to a fixed point. The required free length of cable is coiled on a drum, and the end connected to the appliance remains outside the reel housing. The drum rotates about its axis but is also rotated, simultaneously about a second axis perpendicular to the former. This dual action prevents twisting at the fixed end of the cable. Typically there is a sprocket attached to the drum which engages with a bevel gear inside the housing. As the cable is run in, or out, it rotates the drum and, through the gearing, the drum assembly revolves inside the housing.
