Patent DE-3829207-A1 (DE)
Title: Current-limiting induction coil
Inventor: VOIGT HEINZ DR RER NAT
IPC: H01F6/06
Filed: 1988-08-29
Abstract: The invention relaters to induction coils having cores made of metal oxide ceramic (for example Y-Ba-Cu-O) for limiting the short-circuit current in power supply networks. The current-limiter concept consists in that the inductor core, when used with rated current, is superconducting and keeps the resulting inductance of the inductor low by means of its screening currents. In the event of overload, the winding of the inductor produces a correspondingly high magnetic field in the core, which changes it into the normal conduction state. This results in the screening currents vanishing, together with an increase in the resulting inductance, which ensures limiting of the current (Fig. 1). <IMAGE>

Patent DE-3836405-A1 (DE)
Title: Board arrangement, especially for a valve block of an anti-skid (skid-controlled) hydraulic braking system
Inventor: REINARTZ HANS-DIETER
IPC: B60T8/36
Filed: 1988-10-26
Abstract: A board arrangement is proposed for a valve block of an anti-skid hydraulic braking system having a retaining body (3), which accommodates a board, and having at least one cable which is assigned to the board, the board being constructed as an elastic synthetic-material injection-moulded board (7) having copper conductor tracks which are applied using the hot-embossing process. Previously used, non-elastic boards are subject to high mechanical stresses as a result of their hardness and the risk of brittle fracture in the event of the materials having different thermal expansion, which stresses can lead to premature failures. As a result of the use of elastic synthetic-material injection-moulded boards having copper conductor tracks which are applied using the hot-embossing process, the stresses in the board, and hence in the cable soldering points as well, can be minimised. In particular, the elastic synthetic-material injection-moulded board is suitable for wave-bath soldering, as a result of which the manufacturing process is advantageously influenced from the viewpoint of processing which is as consistent as possible with automatic machines. <IMAGE>

Patent DE-3909240-A1 (DE)
Inventor: DUVE HANS
IPC: G01N33/18
Filed: 1989-03-21
Abstract: 1. Method for continuously and quantitatively determining organic and inorganic carbon compounds (C compounds) in water. 2.1 Hitherto inorganically bound carbon was converted by acidification into carbon dioxide (CO2) which was expelled from the water with a gas. In this process, any readily volatile organic C compounds may also be transferred to the gas phase and evade detection in the liquid phase; they therefore have to be determined separately in the gas phase. The novel method makes it possible to determine the content of C compounds completely and independently of the volatility of the organic C compounds. 2.2 The water to be examined is acidified in an outgassing vessel; a carrier gas stream is passed through the water in the outgassing vessel. Water and carrier gas are fed from the outgassing vessel to a degrading reactor. The CO2 content of the carrier gas is determined downstream of the outgassing vessel and/or downstream of the degrading reactor. The proportions of inorganic and organic C compounds are determined separately from one another and/or as a total. 2.3 Determination of the content of C compounds in water down to the ppb range.

Title: Apparatus for transporting cops and tubes between planes changing in the course of transport
Inventor: GRECKSCH HANS
IPC: B65H67/06
Filed: 1989-03-24
Abstract: In the case of a link between spinning and winding machines, it is often necessary to transport cops and tubes, which stand vertically on pallets, between planes changing in the course of transport. A high flexibility as regards the transport planes and directions of transport and a high transport capacity are desirable here. According to the present invention, carriers, each with two parallel supporting surfaces lying in one plane, are provided for the transport of the pallets. At the same time, the distance between the supporting surfaces, although smaller than the width of the pallets, is nevertheless larger than the transverse dimension of receiving or transferring conveyor belts. The supporting surfaces are mounted rotatably on separate pull means which can be operated in synchronism. The transport means are guided on the receiving side and the transfer side in between the supporting surfaces. This apparatus according to the invention allows continuous movement of the carriers, with the result that a high transport capacity is achieved.   <IMAGE>
