Abstract: The invention relates to a material bed roller mill for crushing brittle material to be ground in the gap between two driven rollers which are pressed against one another with a high grinding force with a filling shaft for the delivery of material provided above the rollers. The width of the stream of material delivered to the roller gap can be altered with the aid of vertical guide walls which are adjustable at right angles to the vertical central plane of the roller mill while maintaining their vertical position. The column of material which is aligned vertically above the rollers creates pressure which is introduced fully into the material bed crushing and if required the column of material can be moved in the cross direction with respect to the rollers.

Abstract: A hydraulically damped rubber cartridge spring incorporates two chamber pairs (4, 6; 5, 7) isolated from one another by a wall (8 ). The chambers are located at a distance from one another in the direction of the introduced vibrations. The chambers of each chamber pair are connected by damping orifices (9, 10) of a channel-like configuration. The damping orifices (9, 10) are so dimensioned and coordinated with the bulge elasticity of the corresponding walls (11) of the bilaternally adjoining chambers, that the contained liquid mass enters into a resonant motion if the vibrations introduced by the spring's operation differ from one another in frequency. The dividing wall (8) contacts the external sleeve (1) loosely when vibrations are not introduced, and at the same time is resiliently deformed toward the internal tube (2) by the external sleeve (1).

Abstract: Recombinant host cells are obtained that comprise (A) a heterologous, polypeptide-encoding polynucleotide segment, stably integrated into a chromosome, which is under transcriptional control of an endogenous promoter and (B) a mutation that effects increased expression of the heterologous segment, resulting in enhanced production by the host cells of each polypeptide encoded by that segment, relative to production of each polypeptide by the host cells in the absence of the mutation. The increased expression thus achieved is retained in the absence of conditions that select for cells displaying such increased expression. When the integrated segment comprises, for example, ethanol-production genes from an efficient ethanol producer like Zymomonas mobilis, recombinant Escherichia coli and other enteric bacterial cells within the present invention are capable of converting a wide range of biomass-derived sugars efficiently to ethanol.

Abstract: An ballast tamping assembly comprises four independently displaceable ballast tamping units arrayed in a line extending transversely to the machine frame elongation. Each ballast tamping unit comprises a carrier frame, a tamping tool carrier vertically adjustably mounted on the carrier frame, and a pair of vibratory tamping tools mounted on the tamping tool carrier for reciprocation in the track direction. Each vibratory tamping tool has a tamping pick remote from the carrier frame and pivotal about an axis extending in the direction of the machine frame elongation and connected to a pivoting drive, and another tamping pick immediately adjacent the carrier frame and fixedly connected to the tamping tool, the remote tamping pick being pivotal between two end positions delimited by respective stops, a first one of the end positions being immediately adjacent the other tamping pick for immersion of the tamping picks at one rail side and the second end position being remote from the other tamping pick for immersion of the tamping picks at respective rail sides. Independently operable drives are connected to the ballast tamping units for displacing the ballast tamping units in a direction extending transversely to the machine frame elongation.
Patent BR-9301817-A (BR)
Inventor: DOMS JAN R P
IPC: C11D17/04
Filed: 1993-05-12
Abstract: A particulate fabric softening composition and a particulate fabric softening detergent composition are described, both of which include bentonite powder agglomerated into larger particulate bead or granule form with a normally solid co-melt of a penta-erythritol compound (PEC), such as pentaerythritol ditallowate (PEDT), and a nonionic surfactant, such as a condensation product of a mole of a C12-15 fatty alcohol with seven moles of ethylene oxide. The fabric softening composition described may be added to wash (or rinse water) but preferably is incorporated in a particulate built synthetic organic anionic and/or nonionic detergent composition to produce a fabric softening detergent composition. The invented detergent compositions are especially suitable for washing laundry in "cold" water, such as water at 40 DEG C. or thereabout, in which the nonionic surfactant increases the dispersibility of the PEC, improves fabric softening activity thereof, in conjunction with the bentonite, and also prevents excessive whitening or chalking of dark colored laundry by the particulate fabric softening composition. These improved results have been attributed to the nonionic surfactant lowering the co-melt's melting point to about 40 DEG C. or lower, at which temperature the softening composition disperses satisfactorily in the wash water. Additional advantages of the invention are a bonus effect of the nonionic surfactant in increasing detergency of the detergent composition and wash water, and in allowing a decrease in PEC content of the softening and detergent compositions without loss of softening effect.

The movable part is coupled via eccentrics to a driving mechanism for introducing an upward and downward oscillation motion in order to prevent the cast steel from remaining stuck to the wall of the mould. In contradistinction to the known oscillating tables according to the invention the eccentrics are not uniformly driven. To this end the driving mechanism comprises driving means for driving the eccentrics with a non-uniform angular speed. In a preferred embodiment the driving means comprise hydraulic motors provided with a control system. The hydraulic motors are electronically synchronised and as a safeguard being coupled to each other by a synchronisation shaft. In this way the facility is obtained to operate any lifting and descending motion of the casting mould.

Abstract: Various kinds of modem control information is stored for each destination, the modem is operated based on stored various kinds of control information to shorten a communication pre-protocol and transmit data when execution is carried out. Also, when a short previous-procedure does not normally proceed, communication is shifted to a second communication procedure whose speed is low so as to continue communication after a lapse of a predetermined period of time. When abnormality occurs after executing the short previous-procedure, various kinds of control information stored in memory means are erased and updated. Therefore, time for communication pre-protocol is shortened, and a mounted short previous-procedure function appropriately operates even when a communication error rate is high or a line characteristic is changed.   <IMAGE>
