Filed: 1984-07-12
Abstract: A safety device, having a hose 4 connected to a stationary mains water supply via a magnetic valve 5, has an outer hose 7 which is pulled over the hose 4. The hose 4 feeds a container 1 of a domestic appliance which has a level switching device 11 which, when a predetermined level of liquid in a vessel is exceeded, closes the magnetic valve 5 and switches on an emptying pump 9. In order, in this case, not to have to provide a special vessel for the case of rupture of the hose, the outer hose 7 is connected directly to the container 1. In this case, the safety-level switch is provided to record the level of liquid in the container 1 and thus records every inlet of water to the container 1 via the hose 4 and via the outer hose 7. <IMAGE>
Patent DE-3426210-A1 (DE)
Title: Method and installation for the production of semi-finished or end products made of metal, in particular steel
Inventor: DEJA ACHIM DR ING
IPC: B21B1/02
Filed: 1984-07-17
Abstract: As is known, a method of this kind presupposes the casting of the molten metal produced in a smelting furnace into ingots followed by an ingot rolling process, and correspondingly large strand lengths have to be processed. A changeover to narrowly delimited diameter gradations and small batch sizes in short time intervals is not possible with the large ingot volumes of the feedstock. In order to make available the feedstock for subsequent forming to semi-finished or end products in a more favourable way in terms of time, with narrowly delimited diameter gradation and with minimum stock holding for single, small, medium and large runs, it is proposed that, after being heated in a furnace, the feedstock, comprising cut-to-length relatively short, rollable charging workpieces (4) with a uniform round or polygonal initial cross-section, be rolled in one heat in a reducing mill (3) to the dimensions of a blank (8) only slightly smaller than the initial cross-section for further working (9) from the same heat with deformation of the core. <IMAGE>

Inventor: BELKA HEINRICH
IPC: B62J7/02
Filed: 1984-08-18
Abstract: A front wheel side luggage carrier (1) for bicycles comprises a strut arrangement (4) having two struts (7, 8), which when in the position of use extend substantially vertically and approximately parallel to a plane that intersects the front axle of the bicycle at right angles, and having an upper and a lower attachment arrangement (5, 6). Via these arrangements, the side luggage carrier (1) is secured to adjacent legs of the front wheel fork (2) at two points, one of which is located near the front axle and the other is spaced apart therefrom. In order to provide a simple structure, which even under adverse conditions will not tend to vibrate during the ride and which will be largely independent of the shape of the front wheel fork (2), the two vertical struts (7, 8) are joined integrally together at their lower end by means of a connecting cross portion (11), which bears the lower attachment arrangement (6). At their upper ends, the two vertical struts (7, 8) are bent toward one another, forming two transverse bent-over portions (23, 24) in alignment with one another, which in turn are bent at their free ends, forming two support struts (27, 28), towards the lower attachment arrangement (6) on which the support struts (27, 28) are anchored. The upper attachment arrangement (5) is provided on the support struts (27, 28).

Title: Process and device for the compression moulding of parts which are provided with an extremely smooth surface
Inventor: HAMNER JAMES R
IPC: B29C33/46
Filed: 1984-09-13
Abstract: For the in-mould coating of plastics parts which are used mainly in the compression moulding of car body outer panels from sheet-shaped composite materials, mould parts are used which are designed such that they form a downwardly curved flange on the outer edges of the moulding. The male mould part has an undercut in order to fix the part to be shaped on the female mould part when the female mould part is raised for the injection of the coating material. The moulding is subsequently ejected from the male mould part with the aid of plates which press upwards on the downwardly curved flange, lifting it from the undercut and detaching the part from the mould. By limiting the contact of the ejector plate on the flange, an extremely smooth main surface of the part with high surface quality is achieved. <IMAGE>

Patent DE-3446804-A1 (DE)
Title: Method and apparatus for consolidating tunnel walls
Inventor: SCHLECHT KARL DIPL ING
IPC: E21D11/10
Filed: 1984-12-21
Abstract: Curved tunnel formwork (1) is fastened to the outer surface of two face arches (12, 13) arranged at a distance from one another and can be pressed with a clamping cylinder (15) against the surface of the section of the concrete shell (16) produced beforehand. At the face arches (12, 13), a truck (2) can be moved over the periphery of the tunnel formwork by means of rollers (2) and a toothed drive (5, 6, 7). At the front side of the truck (2) in the driving direction, a concrete-spraying nozzle (3) is pivotably arranged by means of a universal pivoting device (4) about two axes at right angles to one another. The concrete is fed via a hose line. The concrete-spraying nozzle (3) can cover the unprotected excavation points in the radial direction with a thin concrete layer and secure them from further break-out and can also be used in axial orientation for filling the concrete formwork. Since the spraying nozzle (3) is arranged on the formwork truck close to the tunnel surface, sufficient space remains for the driving and overburden tools so that concreting can be carried out without interrupting the tunnel driving and the removal of the overburden. Furthermore, fall-back of concrete at the tunnel surface is largely avoided, so that fall-back losses can be reduced to a minimum and the mist and dust formation otherwise occurring during the concrete spraying can be largely eliminated. <IMAGE>
