Patent DE-3841115-A1 (DE)
Title: Device for positioning reinforcing elements
Inventor: LANG GUENTER
IPC: E04C5/16
Filed: 1988-12-07
Abstract: Device for positioning reinforcing elements for buildings to be erected by concrete construction work, to which there may be connected the ends of steel reinforcing members intended for parts of buildings which are to be added on. Up until now, for structural parts, such as balconies, which are to be subsequently added on to a building erected by concrete construction work, the steel reinforcing members at the given add-on locations of so-called reinforcing cages, have been permitted to project over the outer wall of the building, said projecting ends being bent back, before concreting, into the reinforcing cages let into the wall. Both bending back and bending out of the reinforcing cages into the desired assembly position result in deformations of the steel reinforcing members which can no longer be eliminated and cause weakness in the reinforcement. The novel arrangement is intended to avoid these disadvantages. The device exhibits at least two clamps which are to be fitted on a spacer at a variable distance from one another and are each to be fastened releasably on a reinforcing element, a coupling for the releasable attachment of connecting steel reinforcing members being provided in each case at the outer ends of the reinforcing elements. The device avoids the necessity of bending the steel reinforcing members or the ends thereof, required for adding on further building parts, for the purpose of embedding in concrete. Consequently, weaknesses in the steel reinforcing members are effectively counteracted and, in addition, highly physical work is rendered superfluous.

Furthermore, the relay has a nominal voltage whose value is less than the nominal value of the positive supply voltage of the device, the nominal voltage of the relay corresponding to the constant voltage of the third terminal.
Patent DE-3900205-A1 (DE)
Title: Water-soluble cores for forming cavity chambers or cavity body components in non-ferrous castings
IPC: B22C9/10
Filed: 1989-01-05
Abstract: Hitherto used cores of lithogenic components, bonded with resins, starches and carbon dioxide, are consolidated under the action of temperature and pressure. The destruction therefore becomes very involved. As a result of the preparation by means of compression-moulding processes, less than optimum contours must sometimes be accepted. The object is achieved by forming lithogenic core materials with water-soluble binders into cores which ensure a high initial stability which they lose under the influence of pressure and temperature. At the same time cores can thus be produced by foundry technology, the core components used being re-usable by addition of water and binder. Water-soluble cores are particularly suitable for the formation of cavity chambers which are accessible only via small orifices and in the case of which the conventional elimination processes are very involved.
