Title: Method and apparatus for producing underground pipelines, in particular for civil engineering
Inventor: PFEIFFER LUDWIG
IPC: E21B23/08
Filed: 1985-05-31
Abstract: The invention relates to a method and an apparatus for producing underground pipelines, in particular for civil engineering, in which an underground through-bore is formed and a multiplicity of pipe elements forming the pipeline are pushed one behind the other into this through-bore. Until now powerful pressure forces have had to be applied to drive the pipe elements forward on account of the considerable friction forces. This leads to a restriction in the length of the pipelines to about 100 m if intermediate pressure stations are not to be provided or cannot be provided. The method according to the invention removes this disadvantage owing to the fact that the through-bore (1) is bored with a larger cross-section compared with the external cross-section of the pipe elements (4), the hollow space (5) between the wall of the developing through-bore (1) and the outer circumferences of the gradually advanced pipe elements (4) is filled with a free-flowing medium (30), and the advance of the pipe elements (4) is carried out while utilising the buoyancy effected by the medium. In addition, the invention proposes an apparatus by means of which the said method can be realised with simple means. <IMAGE>

Title: Method and arrangement for delivering gases at a slight vacuum through gas-line systems at risk of settlement, in particular in landfill sites
Inventor: HAASE HARRY
IPC: B09B1/00
Filed: 1985-07-29
Abstract: In the delivery of gases at a slight vacuum through gas-line systems at risk of settlement, in particular in landfill sites, by means of individual delivery strings run from gas-extraction bores to a common vacuum unit ... delivery-line traps and deformed by settlement of the material of the landfill site, in order to ... and thus avoid an increase in the vacuum in free delivery strings and also maintain a uniform delivery capacity in line systems tending to trap water without substantial construction measures, it is proposed to individually and constantly regulate the volumetric gas flow in the individual delivery strings of the gas-line system. To carry out this method, a gas-delivery arrangement is proposed in which a control station (4) with a gas volumeter (42) and a pressure regulator (41) controlled by the latter is allocated to each individual delivery string (3, 31) or each gas-extraction bore (2). <IMAGE>

Title: Lateral shearing interferometer for phase-different measurement of two wave fronts of constant phase
Inventor: THIEME REINHARD
IPC: G01J9/02
Filed: 1985-09-05
Abstract: Lateral-shearing interferometer for phase-different measurement of wave fronts. This two-beam interferometer is used for measuring the deviation of a test wave front from a planar wave front, and for measuring the deviation from the spherical shape in the case of a slightly curved wave front. These measurements are used, for example, for testing optical systems. In this case, the lateral offset of the wave fronts at right angles to the propagation direction of the light, so-called lateral shear, is brought about only by mirrors and can be adjusted independently of the path-length difference of the sub-beam paths. The path lengths of the sub-beam paths can be tuned to zero, the white-light position, and do not influence the lateral shear.

Title: Erasing method for magnetic, moved, sheet-like information stores
Inventor: GREINER JOACHIM DR
IPC: G11B5/024
Filed: 1985-11-22
Abstract: The invention specifies a method with associated arrangements for erasing anisotropic, sheet-like, dynamic information stores. These stores have an axis of anisotropy which stands perpendicularly on a plane of anisotropy. Either the axis is the difficult magnetic direction and the plane is the easy direction or vice versa. The axis and the planes always coincide in some way with the preferred coordinate directions of the storing operation (running direction etc.). In contrast to conventional erasing methods by alternating field or heat, the perfect random distribution of the magnetic regions with respect to the size and direction of the magnetic moment and of the coercive field, with consideration for the anisotropic properties of the storage medium, is achieved by a single-acting d.c. magnetic field, which goes approximately from the magnetic saturation field strength of the magnetic material in the difficult axis monotonously to zero without changing direction. Storage materials and field arrangements are described by way of example.

For this purpose, a pressure tube (18), which can be connected to a compressed-air source via a valve (21) attached to the post (3), bears against each bearing bar (23). The base (2) may also be mobile by way of castors (28), and the supporting bars (6) can be lengthened telescopically or by frontal connection. The gluing apparatus is of simple and well-arranged construction, and of compact and operationally reliable design. It is easy to operate and move and can be accommodated in defined spaces, especially low spaces. In addition, the production and operating costs are low. <IMAGE>

Title: Inertial navigation system, preferably for surveying purposes
Inventor: MAROLD THOMAS DIPL PHYS
IPC: G01C15/00
Filed: 1987-05-29
Abstract: The system has an inertial measuring unit and a processor, preferably for a portable inertial navigation system, by means of which the point coordinates of the points to be surveyed are obtained without an operator of the device having to determine or to take into consideration the eccentricity. This is achieved by a point on the housing of the inertial navigation system being provided as a reference point for the measurements, the point coordinates of the points to be surveyed, which are determined, referring to this point and the eccentricity vector from the reference point to the centre of the inertial measuring unit being stored in the processor. It is advantageous that the reference point is a spatial corner, the angles of the corner are 90@, the adjoining edges and areas of the housing being straight and level and that the angles between the edges adjoining the corner and the coordinate axes in which the point coordinates of the point to be surveyed are determined are indicated after retrieval.
