Title: Web-shaped filter material, in particular filter paper for liquid filters or gas filters, having moulded beads
IPC: B01D29/01
Filed: 1988-05-04
Granted: 1989-09-21
Abstract: In a web-shaped filter material, in particular filter paper for liquid filters or gas filters having moulded beads, in which the filter material is folded in a zigzag shape into individual sections and these sections are spaced from each other by the beads, the stiffness and the strength of the beads is to be increased in order to prevent loss of the spacing action of the beads after relatively long service lives. This is achieved by the filter material having a thickness in cross-sections perpendicular to the plane of the web, which thickness continuously decreases within the region of the beads starting from the undeformed filter web sections as far as a zenith height H of the individual beads, and the filter material being increasingly compressed in the course of this for the decreasing thickness. The ratio of zenith height H to width B of a bead is to be as far as possible less than 2. <IMAGE>
Patent DE-3841772-C1 (DE)
IPC: B62D53/00
Filed: 1988-12-12
Granted: 1990-01-18
Abstract: The vehicle comprises sections (3, 4), axes (6, 6', 7) and centre joint (5) arranged centre-symmetrically. The vehicle is fully operational in both directions of travel by means of driver's cabins (12, 12') at both ends of the vehicle. All axles (6, 6', 7) are steerable; the outer axes (6, 6') are driving axes. Lateral-guidance rollers 13 are mounted near the outer axes (6, 6') and interact with runners (28, 28') along the roadway. The axes (6, 6') can be optionally manually steered in each case from the nearest driver's cabin. All vehicle axes can be blocked in the straight-ahead position. The centre axle (7) is coincident with the joint (5) and is non-rotatably coupled to vehicle sections (3). Selection of the direction of travel automatically blocks or allows steering of the axes; for example, the wheels of the centre axle (7) are steerable only if the single-axle vehicle section (4) is leading, as in Fig. 5.   <IMAGE>

Title: Low-noise SPI-single point NMR imaging method
Inventor: NAUERTH ARNO
IPC: G01R33/54
Filed: 1993-10-06
Granted: 1995-03-23
Abstract: In the case of an SPI method for n-dimensional NMR imaging for materials having short T2 relaxation times, for example cartilage or bones, only a single measurement point in k-space is acquired from the phase-encoded FID signal after each RF excitation pulse. From the k-space points obtained, a pseudo spin echo (4) can be obtained, which essentially carries the same information as a conventional spin echo signal. In order to avoid excessive noise development when switching the gradients, provision is made for the gradients to be applied also during the waiting times between the acquisition of individual points, and for the stepwise change in the gradient fields from one individual point to the next to be carried out in such a way that at least one of the gradient fields is not completely switched off between two individual points, but is respectively changed only by an increment value which is very small compared with the maximum value of the relevant gradient fields, the quantity of the increment value corresponding to from one to z times the separation of two neighbouring points in k-space, and preferably with z < 5. <IMAGE>

Title: Mineral wool fibre material prodn. in vertical layers
Inventor: KLOSE GERD-RUEDIGER DR ING
IPC: D04H1/74
Filed: 1994-09-15
Granted: 1996-02-01
Abstract: To produce a length of mineral fibre material (29) with vertical fibre alignment, the mineral fibres (18) are sprayed with a bonding agent in a collection chamber (1) to be gathered by suction at a collecting gatherer (6) for onwards movement. The fibres are caught by the separate successive segments (8-11) of the carrier (6) through suction through their permeable surfaces, to be carried out of the collection chamber in segments, and then blown (15) clear of the transport system. The segment layers (19-21) of fibres are passed in succession to a conveyor belt (27), vertically to the belt movement direction. They are compressed into a material (29) by pressure (28) to the required thickness, to be passed to a kiln to set the bonding agent.  Also claimed is an appts. with a carrier (6) of segments (8-11) which come into action in succession through the unit (6) rotation. The suction through the permeable segment surfaces collects fibres from the chamber (1) as a layer on each, applied by a suction chamber (12) within the unit (6). An internal blowing chamber (15) faces the segment (10) at the discharge position. A conveyor belt (27), below the blowing station (15), takes the ejected fibre layers vertically to the belt movement, in succession, to form a material (29) of vertical fibre segments. They are compressed (28) to the required thickness before passing to a kiln to set the bonding agent.

Abstract: FIELD: oil and gas production. SUBSTANCE: method consists in forming gas stream, separation and withdrawal of impurities, cooling by heat exchange technics, and low-temperature separation and withdrawal of impurities. According to invention, separation of impurities is effected using laminar flow of gas stream through vertical layer of hydrocarbon liquid and low-temperature separation is effected in the same way at - 30 to -120 C. Impurities are withdrawn automatically when predetermined content of impurity in liquid layer is reached. Gas stream flows from below upwards in the form of small bubbles, and, as liquid, hydrocarbon, gas condensate with low hardening temperature is used. After low-temperature separation, gas stream is additionally subjected to centrifugal separation and then to heat-exchange heating with gas stream to be cooled after separation. Installation contains following interconnected constituents: inlet line; separator connected through locking device to impurity collector; heat exchanger; low- temperature separator connected through locking device to impurity collector; and outlet line. According to invention, before inlet line, gas collector is installed; inlet line is constructed in the form of gander; separator contains vertical column enclosing two float members, one being disposed in middle and the other in upper part of column; low-temperature separator contains heat-insulated vertical column enclosing float member and heat exchanger connected to cold- production installation in its upper part.
