Abstract: The invention relates to a process for tanning acidified wet raw hides. This process consists (a) in preparing a water-insoluble organic liquid bath, (b) in suspending in this bath an inorganic tanning agent based on a metal compound, especially a chromium salt or complex, (c) in adjusting the degree of hydration of the hides above a minimum threshold of 200% (weight of water added to the dry weight of hides) and below a maximum threshold corresponding to the limit of retention of water in the hide, (d) in bringing the hides thus hydrated into contact in the organic bath containing the tanning agent for a period of at least 4 hours and in slowly introducing a base into the bath so as gradually to raise the pH of the water retained in the hides to a final value of between a minimum threshold of 3.9 in the case of a chrome tanning agent, and a maximum threshold of 4.4 in the case of this chrome agent, and (e) in removing the hides from the bath and leaving them to rest for at least 24 hours. The process of the invention makes it possible to obtain at the same time a complete exhaustion of the tanning bath, an absence of release of tanning agent in the subsequent finishing operations and a leather of good quality.

Abstract: In a process for reducing the sulfur and ash contents of coal, coal is sequentially contacted with fused alkali metal caustic, wash water, and acid. Contacting the coal with the caustic produces water-soluble compounds. Sufficient wash water is used to reduce the temperature of the caustic treated coal and dissolve the bulk of the water-soluble compounds before the water-soluble compounds convert to water-insoluble compounds that precipitate on the caustic-treated coal. Caustic removed from the coal by the water is recovered as anhydrous caustic for again contacting coal.

Abstract: Multiple latching relays are driven on their first side (12) by all but one of the parallel outputs of a buffered shift register B.S.R. (11 a, 11 ...). Each relay on the same B.S.R. is driven on its second side (19) by the remaining parallel output of the B.S.R. A clock signal is fed to all B.S.R.s by a line (17), and causes each B.S.R. to shift all of its information one cell on the selected hedge of the clock signal. A latch signal or blanking signal is used to prevent the B.S.R.s from outputting their information to the relays during shifting. The latch or blanking signal is fed to all B.S.R.s by a line (18). A serial data message is inputted to the first B.S.R. at its serial data input (16a) . The serial data output (15) of each B.S.R. is fed to the serial data input of the succeeding B.S.R. (e.g. 16b). The information in the serial data message is such that after the shifting of all B.S.R.s is complete the appropriate signal will be on each side of each latching relay to cause it to either change or remain unchanged, as desired. The result is that one serial data line, one clock line (17), and one latching or blanking line (18), controls all of the relays. Additional latching relays can be controlled simply by adding more B.S.R.s and sending more data down the serial data line. 
     Shift Registers which are not internally buffered may be used in an identical fashion to B.S.R.s if suitable external buffers are used. A suitable buffer must be placed between each of the outputs (13) of each Shift Register which are connected to the first sides of the latching relays, and the first side (12) of the latching relay it is coupled with, and a suitable buffer must be placed between the remaining output (14) of each Shift Register and all of the second sides of the latching relays it is coupled with.

The element of the first group provides stable nucleant particles in the melt. The element of the second groups forms an intermetallic phase such that crystals of the phase form in advance of and nucleate primary Si to provide complex particles which promote nucleation of Al-Si eutectic on cooling of the melt below the eutectic solidification temperature. The level of each of the elements of the first and second groups is such that, on solidification of the melt, the casting has a microstructure in which any primary Si present is substantially uniformly dispersed, and in which the microstructure predominantly comprises a eutectic matrix. The element of the first group is not solely Ti where the element of the second group is solely Sr.

Abstract: An apparatus for capillary zone electrophoresis having a selectively removable capillary cassette (10), the internal walls of which define a toroidal capillary region and a gas flow path therethrough. Within the capillary region is housed a helically wound capillary tube (16) having an inlet end (24) and an outlet end (40). An electrical field is applied across the ends of the tube to cause electrophoretic separation of molecules of a sample. A stream of pressurized gas, preferably air, is channeled through the capillary region for cooling of the tube. The gas flow is a transverse flow and is channeled to avoid differentiation in cooling capacity. The transverse cross-sectional area of the gas flow path is substantially uniform throughout to prevent change in flow velocity. The gas flow path is a generally U-shaped path having a smooth radius turn. In progressing through the capillary region, the stream of gas is caused to flow at an angle relative to the axis of the helix, thereby promoting thermal isolation of succeeding loops of the helically wound capillary tube.
