Title: Arrangement for guiding a traction cable
Inventor: BRANDIS CURT DIPL ING
IPC: E01B25/18
Filed: 1988-10-07
Abstract: A roller block 6 which is particularly suitable for double traction comprises an S-shaped rocker 18 which is mounted so as to be pivotable to a limited degree about a vertical axis 27. At the end of the rocker 18, closing rollers 15, 15a which can rotate about horizontal axes 14 are arranged as a component of roller windows 8 or 9, offset in the longitudinal and in the transverse directions, for guiding the traction cables 4, 5. The rocker 18 also has lateral stopping faces 23, 23a which can gently be brought into contact with pivot rollers 25, 25a and are provided on the traction vehicle 1 in the vicinity of the cable arms 2, 3. Springs 22 ensure a restoring moment of the rocker 18 into the closed position. For single-cable operation only one roller window is present and the rocker bears only one closing roller. <IMAGE>

Title: Line protection device
Inventor: KIRTLAND DENNIS ALFRED
IPC: F16G13/16
Filed: 1988-11-15
Abstract: In order to protect cables, connecting lines, supply lines and the like, especially in longwall working, a hinged arrangement is formed from a plurality of interconnected elements. Each element has a central web (10) which forms a common base for a pair of laterally open channels (16, 18) which are arranged on the sides of the web. In the case of at least some of the elements, each channel side (12, 14) is provided with an inwardly extending bead (28) which form an inlet (30, 32) to the respective channel, the width of the inlet being smaller than the relevant channel. The device is essentially formed from plastic material with elastically flexible channel sides, so that a cable or a connecting line or supply line can be inserted into the respective channel (16, 18), with the channel limbs bending away from one another. Once the cable or the connecting line or supply line has passed through the channel inlet, the channel sides (12, 14) return to their original position and prevent the line inadvertently emerging from the channel. <IMAGE>

Inventor: LAURILA MELVIN JAMES
IPC: G01N23/12
Filed: 1988-12-02
Abstract: An on-line slurry ash monitoring system 10 for evaluating the composition of coal slurries in coal preparation plants. A coal slurry is introduced into a sample reservoir 24 where it is removed and passed through a closed loop slurry transport system which causes the sample to be directed through a sensor 16 and recirculated back to the reservoir 44. In order to enhance sensor accuracy, a sample is exposed to vacuum pressure conditions which removes entrained gas bubbles within the system. The sensor 16 is preferably a radiation transmission type in which characteristic absorptions of coal particles, ash and iron are evaluated by associated electronics to provide an output of slurry composition. <IMAGE>

Title: Smoothing or metering device
Inventor: SOLLINGER HANS-PETER DR
IPC: D21H25/12
Filed: 1989-03-08
Abstract: A rotatably driven doctor rod (roller doctor rod, preferably with circumferential grooves) is vibrated at one end in the axial direction by impacts of high frequency, preferably, for example, by means of a piezoelectric translator, but preferably by electromagnets or a hydraulic exciter. This prevents the formation of air bubbles on the doctor rod, in particular in the circumferential grooves, and thus streakiness of the spreading application insofar as the latter is caused by this phenomenon.

Title: Spring suspension of a motor vehicle wheel
Inventor: FIALA ERNST PROF DR
IPC: B60G15/06
Filed: 1989-04-25
Abstract: Wheel suspensions are known in which the body oscillations and the comparatively higher wheel oscillations are damped separately from one another, that is by a hydraulic telescopic shock absorber, arranged between wheel carrier (stub axle) and vehicle body, on the one hand, which shock absorber is preferably part of a spring strut, and by a vibration absorber on the other. The new wheel suspension is intended to allow such a combination of conventional telescopic shock absorber and vibration absorber to be also used in modern spring strut or damper strut axles, in which the spaces close to the centre of gravity of the unsprung masses, that is the wheels, are generally very restricted. In order to obtain an especially compact, space-saving construction, the vibration absorber is fixed on the damper or cylinder tube of the telescopic shock absorber in such a way that its absorber mass encloses at least a part of the shock absorber tube circumference with clearance. <IMAGE>

Title: Clamping device - with one hydraulic piston for several clamping surfaces
Inventor: PIJPERS TEUNIS
IPC: B29C45/17
Filed: 1989-06-09
Abstract: A clamping device for the temporary fixing of two parts in relative motion to each other, e.g. tooling moving relative to the frame of a plastic injection moulding machine, has a double-acting piston (1) with a piston rod (2) which is hydraulically displaceable in a cylinder (13) along its axis (9) in order to adjust two first clamping surfaces (6, 7) axially. Each of them is attached to the free end of carriers (4, 5) to interact with (not shown) second clamping surfaces. Guides (14, 15) permit their axial free movement. A coupling link (3) joins the piston (1) to cross pins (8). ADVANTAGE - This needs only one piston to operate several clamping surfaces.
Patent DE-3926363-A1 (DE)
Inventor: SCHULZE REINHARD
IPC: H05B6/80
Filed: 1989-08-10
Abstract: The invention relates to a process for liquefying mixtures of organic substances, in particular in the manufacture of perfumes, by exposing them to a microwave field of predetermined rated frequency, at least one component of the mixture being absorbent when introduced as well as in a predetermined temperature range and in the range of the rated microwave frequency. The process permits sufficiently uniform and hence decomposition-free heat treatment, in particular liquefaction, of mixtures of sensitive organic substances. To this end, the mixtures are exposed to the microwaves in a resonance chamber which is reflectively limited on essentially all sides and in which the microwaves undergo mode and frequency splitting. The principal dimensions (x, y, z) of the resonance chamber are not less than approximately eight times the free space wavelength of the microwave field at the rated frequency.

Title: Clay mould - has shaped filter layer as the mould for water to be forced from the clay through the filter by high pressure
Inventor: SCHNORR MARIN
IPC: B28B1/26
Filed: 1990-01-19
Abstract: To produce clay blanks (6), in a thin walled or solid or hollow shape, the fluid clay material is fed into a water permeable mould of negative shape to fill it. A high pressure is applied, pref. above 100 bar, and water is forced out of the clay material. Pref. after moulding, remaining fluid clay material is removed and the moulded clay in the mould is subjected to further pressure by air at a high pressure, pref. above 100 bar. Compressed air is used to remove the blank (6) and/or to extract water from the mould and/or to remove surplus fluid clay. Within a pressure sealed housing a pressure resistant filter layer (5) gives the negative shape of the blank (6) to be formed. A support (4) between the filter layer (5) and the housing has hollow zones to lead off water pressed out of the clay through the filter layer (5). A connection (7) gives the feed of the prepared fluid clay and a connection (8) for compressed air removes surplus liquid clay. The housing is fitted with at least one opening (9). The housing is in at least two parts (2.1,2.2) and at least one frame is round the housing. The filter layer (5) is a porous fired ceramic material. The support (4) between the filter (5) and the housing is loose gravel bonded by synthetic resin. A compressed air connection is fitted to the opening (9) in the housing. A membrane separates the clay and the pressure medium. Inserts (12), with low or no porosity, cover part of the filter layer (5). The filter layer (5) has zones of different porosity and different thicknesses. ADVANTAGE - The process does not require plaster moulds so mould drying and energy costs are eliminated.
