Title: Conditioning of oil-contg. sludge for disposal - by mixing with solid and then coating
Inventor: IFFLAND NORBERT
IPC: C08L95/00
Filed: 1977-04-21
Abstract: Conditioning of waste sludges contg. mineral oil for disposal is carried out by first mixing the sludge with high-mol.-wt., porous and absorbent solids (I) to convert it into powder or granular form, and then coating it with a coating compsn. to produce a product with the required consistency for disposal. The process can be applied, e.g., to oil-contg. metal hydroxide sludges from the electroplating industry, acid resins and oil-loaded bleaching earths from used oil processing, and residues from metal working or coal treatment. The consistency of the product can be varied widely without an excessive increase in vol. Contaminants in the sludge do not interfere with the hardening of the coating.

Title: Hydraulic power press with servo-control - has mechanical feed back system actuated by chain or cable
Inventor: VASILKOVSKY VITALY PANKRATIEVI
IPC: B30B15/16
Filed: 1977-05-17
Abstract: The servo-control of a hydraulic press has a mechanical feed back system. The cross-head of the press is connected by chain or cable to a drum which rotates on a screwed shaft. As the drum rotates it approaches the worm wheel and when the projections come into engagement the worm is pushed in the axial direction. This axial motion of the worm is transmitted through the shaft and hydraulic intensifier to the camshaft (28) of the control valve. When the control lever is actuated in order to move the cross-head to a required position, the camshaft (33) is rotated. This rotation of the camshaft actuates the control valve which directs hydraulic fluid to the jacks. When the cross-head has reached this required position the feed back mechanism closes the control valve and stops the cross-head.

Title: Sound level regulation of alarm bell - uses bell shells mounted on strip deformed to move away from striker
Inventor: HASCHKE KURT
IPC: G10K1/064
Filed: 1977-09-09
Abstract: A mechanical alarm bell is designed to allow the sound level to be easily varied. Two hemispherical shells are struck by an oscillating hammer located between them. The hemispherical shells are mounted on a common strip of deformable material (6, 7). An eccentric (13) may be rotated to cause the strip to deflect and so move the shells away from the striker. The sound generated is therefore varied accordingly. The plate (3) is fixed to the baseplate (12) by screws (8, 9) and similar screws (4, 5) are fitted to the centres of the hemispherical shells (1, 2).

Patent DE-2801172-A1 (DE)
Title: Synthetic fibre strand washing - uses the washing fluid as the carrier medium to transport strands through tubes
Inventor: PREUSSER GERHARD DIPL ING
IPC: D06B3/04
Filed: 1978-01-12
Abstract: The process to wash strand material, partic. of synthetic fibres, uses the effects of fluid friction to carry the material through the washing fluid. Because of the difference in specific gravities between the water and the synthetic fibres, the strand material moves more slowly so that it is carried smoothly through the washing process without requiring mechanical handling. The washing and transport of the strand material is effected in a tubular closed unit, and can be in a number of stages with opposing current streams. The washing and carrying fluid is recirculated in each washing stage, and the movement is imparted by the injection of a partial fluid stream into the system, or by the injection of a driving gas or steam.

Title: Solidifying aq. sludge or pasty waste - e.g. oil, by adding calcium sulphate to form calcium sulphate di:hydrate
Inventor: POCH WINGOLF DIPL CHEM DR
IPC: C04B28/14
Filed: 1978-03-09
Abstract: Solidified prods. of aq. sludges or pastes and setting agents contain CaSO4.2H2O. The prods. are produced by adding CaSO4, pref. contg. less water of crystallisation than CaSO4.2H2O, to the aq. sludges or pastes.
