Title: Thermo:well extn. of viscous oil - by steam injection in deposit through radial network of uncased holes
Inventor: LICHOLAJ VASILIJ KONSTANTINOVI
IPC: E21B36/00
Filed: 1980-01-07
Abstract: High-viscosity mineral oil which cannot be extracted by conventional wells from its deposit is won by a thermowell system. Downcast and upcast pits are sunk down to the deposit and the lease is subdivided in square panels, reached by airways and galleries. From a cavity in the centre of each panel, a network of inclined and horizontal radial boreholes are drilled and provided with steam pipes throughout. Boreholes sunk from the surface in each cavity introduce steam which is passed through a restrictor into each radial pipe. Another pipe with a pump at the bottom removes the mixture of oil, condensate and sand to a separator tank on the surface. This creates a more effective system of fluidising viscous mineral oil or bitumen with a min. of heat losses.

Title: Spacer for the outer sheath (which is preferably constructed as a protective casing) of a heat and sound insulating layer on pipelines, boilers, facades or the like
Inventor: FISCHER WOLFGANG
IPC: F16L59/12
Filed: 1981-02-11
Abstract: In the case of a spacer for the outer sheath (16) (which is preferably constructed as a protective casing) of a heat and sound insulating layer (24) on pipelines, boilers, facades or the like (1) in the form of a web (9) (which is supported directly on the pipeline, the boiler or the facade and in a spring manner on the sheath (16), in each case essentially in the direction of the respective normals to the surface), it is intended on the one hand in a simple manner to prevent transmission of the vibration or body sound originating from the pipeline, boiler wall or facade to the sheath (which is preferably constructed as a protective casing), but on the other hand for the sheath to have adequate stability against external mechanical stresses, such as people stepping on it, wind action, snow load or the like, which is achieved in that the end of the web (9) facing the sheath merges into a spring (13) which has a flatter characteristic in the direction of the normals to the surface of the sheath than in the direction of the surface tangents associated with these normals to the surface. The spring (13) consists of a coiled spring section which is bent in the form of a bracket and is inserted between the sheath and the end of the web (9) facing the said sheath. The coiled spring section which is bent in the form of a bracket can be formed into a closed oval. The spring expediently consists of spring steel. The spring movement of the spring in the direction of the normals to the surface can be limited by a fixed, possibly adjustable stop (14). A heat-insulating section (9), consisting of materials having a low thermal conductivity, can be provided between the spring (13) and the wall (1). This heat-insulating section (9) expediently extends from the wall (1) as far as the spring (13). However, it can also consist of a pin (9) composed of a ceramic material, or can be produced from an organic fibre material. An additional element, which acts as a mass, can be arranged rigidly on the spring (13), on the side of the sheath. It is also possible to arrange a holder on the spring (13), on the side of the sheath, for attachment of the insulation layer. <IMAGE>

Title: Measuring head for a laser Doppler vibrometer
Inventor: STOFFREGEN BERND DIPL PHYS DR
IPC: G01H9/00
Filed: 1981-04-01
Abstract: In a laser Doppler vibrometer, a Bragg cell (3) immediately adjacent to the laser (2) is used both to obtain a primary beam (4) directed straight onto the object and to obtain a reference beam (5) which is frequency-shifted relative thereto; its control voltage is set such that the reference beam (5) and the radiation (13) back-scattered at the object have approximately the same intensity when superimposed. This renders mechanical adjustment of individual components of the vibrometer superfluous with regard to differing object properties. The beat frequency of the radiation produced by the superimposition is detected by means of photodiodes (14, 15) as a characteristic of the object vibration. <IMAGE>
