Patent EP-0188282-A2 (EP)
Inventor: ESTERS KLAUS
IPC: E02D19/12
Filed: 1986-01-15
Abstract: The impervious sealing and the production method for it make it possible to replace the expensive methods of shield tunnelling or freezing and as a result eliminate interference with the ground-water balance and prepare the ground masses to be excavated in such a way that they can be continuously excavated in timed sequence with the subterranean construction from a secured position and in the dry. This is achieved by virtue of the fact that the impervious sealing consists of an elastic sealing jacket (3) which is formed from sealing walls (2) arranged in the form of a canopy, screen, housing or the like and which hermetically seals off the ground masses (5) to be excavated from the ground water (4) and/or from air. In the production method provided for this, the ground masses (5) in place of a site to be driven dry are sealed off from the ground water (4) and/or the air by a sealing jacket, are dewatered, are compacted under the pressure of the ground water (4) in place on the outside of the sealing jacket (3) and/or are stabilised by applying a vacuum. <IMAGE>

Abstract: The invention relates to a device usable in an amusement park in association with a rotatable carousel having a support arm which supports a cylindrical bearing for a car which is used to accommodate one or more persons. The cylindrical bearing is held substantially vertically so that it defines a rotatable horizontal axis which rotatably supports the car. The car is suspended so that the center of gravity of the car holds in a position so that it accommodates the passengers in an upright position. Means are provided to bias the car into an upright position, but to permit it to rotate about its horizontal axis. A feature of the construction is that the car is provided with a control which may be manipulated by a passenger to orient wings of the device so that the device has a tendency to effect a roll about its horizontal axis. In addition it is provided with a similar control, or the same control which effects the driving rotation of the car about its central horizontal axis so that it begins a roll against the biasing action to which it is mounted. The ring mounting the car to the carousel support is constructed so that it may be centrally suspended from the support along with the front end thereof which permits the rotation about the horizontal axis.

Abstract: An electric switch whose switching mechanism has at least one fixed contact and at least one movable contact interacting therewith must be waterproof for specific applications. Sealing is easier if there are fewer points which have to be sealed. A particularly advantageous solution is achieved according to the invention by the switch housing being produced as one piece and having at most two, but particularly only a single assembly opening, which can be closed by means of a base or the like holding the switching mechanism. From the assembly point of view, it is particularly advantageous if the base is retained by a force-fit and/or positive lock and the interior of the housing is closed in a sealed manner to the atmosphere by means of at least one sealing element connected between the base and the switch housing. In the case of a switch with a ram passing through to the outside, the latter is expediently sealed with respect to the housing by means of an elastic collar or the like. <IMAGE>

Abstract: According to the invention, cyanide concentrations of approximately 0.001 to 5 mg cyanide/1 are colorimetrically determined in a continuous manner by means of the known cyanidepicric acid color reaction. The solution containing free cyanide and/or cyanide releasable from cyanocomplexes is converted in a system enclosed in a gas-tight manner in the presence of chelate complexing agents, picric acid and alkaline buffer systems in 1-60 minutes at 50 DEG -120 DEG C. to the color complex and the absorbency is measured spectrophotometrically. The method avoids the extraction step which was previously necessary under 0.2 mg CN/1, avoids errors due to HCN gas evolution losses, is easy to manage, not prone to trouble and suitable for the continuous monitoring of waste-water streams or for controlling cyanide detoxification methods.

Abstract: A process and apparatus for fabricating expandable honeycomb materials (172) are disclosed. Adhesive is first applied along the length of a continuous material (14) by first heating the material (14), applying the adhesive (18) in a liquid state to the heated material (14), and then cooling the material (14) to solidify the adhesive. The continuous length of material (14) is folded along opposite side portions thereof into a generally flat tubular form having upper and lower layers. The folded tubular material (74) with solidified adhesive lines thereon is then wound about a rack (120) in such a manner that the tubular material (74) is deposited in a plurality of continuous layers one on another with the lines of adhesive (18) being disposed between adjacent layers. The wound layers (74) are then radially cut (122) and placed in a vertically aligned stack while they are removed from the rack (120). The vertically stacked layers are then heated to a temperature sufficient to activate the lines of adhesive (18) and bond the layers together. Finally, the stacked tubular material is cooled to form a unitary stack of tubular, expandable honeycomb material (172). A device for performing the process as described above is also disclosed.
