Abstract: A process for producing, recovering and purifying lactate from a fermentation broth so that it can be efficiently and economically converted to lactic acid is disclosed. The process comprises growing a high lactate producing, microorganism on an inexpensive substrate until a whole broth containing about 75 to about 90 grams of lactate salt is obtained. The whole broth including the viable cells is then electrodialyzed in a unit (10) having anionic-permeable (20) and cationic-permeable (19) membranes to cause the lactate salt to concentrate in an aqueous liquid which can be treated to convert the lactate salt to lactic acid.

Abstract: In order to assemble the components of an electrochemical generator using lithium, which are in the form of thin films and comprise a lithium- or lithium alloy-based negative electrode and a solid polymer electrolyte with conduction using the lithium ion, an intermediate assembly is used which consists of a thin film of lithium supported by a film of inert plastic with controlled adhesion to the lithium, as a precursor of the negative electrode. This intermediate assembly can be produced, inter alia, by rolling a sheet of lithium between two films of inert plastic.

Abstract: The invention relates to a method of manufacturing a belt pulley consisting of a metal disc, such as a poly-V-belt pulley, a toothed belt pulley, a flat belt pulley etc., having a hub and a region whose basic shape is a hollow cylinder, which is externally smooth or cambered, or is provided with a profile running in the circumferential or lateral direction, and whose material thickness can be greater than that of the hub, the metal disc being profiled in a corrugated shape in its circumferential region in a first step of the method and the respective finished profile being produced in further steps of the method. 
<??>Known methods require a large number of process steps and a large amount of force for forming. The new method is intended to allow high- quality belt pulleys to be produced from metal discs with a comparatively low outlay for carrying out the method. 
<??>The new method is characterised in that, in a second step of the method, the circumferential region (11), profiled in a corrugated shape, of the metal disc (1) is rolled into a shape, which is corrugated when seen in cross-section, with a corrugation maximum (12, 12') in each case on the edge side, pointing outwards in the radial direction, and laterally adjacent wave minima (13, 13'), pointing inwards, so that a contour is produced having a corrugated shape with optimum material distribution for further processing.

Abstract: The electroviscous fluid is a suspension composed of a finely divided dielectric solid dispersed in an electrically nonconductive oil. The viscosity of the fluid increases swiftly and reversibly under an influence of electric field applied thereto and the fluid turns to a state of plastic or solid when the influence is sufficiently strong. 
     The electroviscous fluid of the present invention comprises 1- 60% by weight of a dispersed phase of carbonaceous particulates having average particle size of 0.01-100 micrometer, and 99-40% by weight of a continuous liquid phase of an electric insulating oil having a viscosity of 0.65-500 centistokes at room temperature. 
     The electroviscous fluid exhibits an excellent electroviscous effect even at a high temperature with a low electric power consumption together with maintaining the improved electroviscous effect for a long period of time.

Abstract: A bistable electronically controlled pneumatically powered transducer for use, for example, as a valve mechanism actuator in an internal combustion engine is disclosed. The transducer has a piston (13) which is coupled to an engine valve, for example. The piston is powered by a pneumatic source (39) and is held in each of its extreme positions by pneumatic pressure under the control of control valves (15, 17) which are in turn held in their closed positions by pressurized air and/or permanent magnet latching arrangements (25, 27) and are released therefrom to supply air to the piston to be pneumatically driven to the other extreme position by an electromagnetic neutralization (24, 26) of the permanent magnet field. A pair of auxiliary pistons movable with the piston compress air to a pressure above the pressure of the pneumatic source for aiding reclosure of the control valves (15,  17) as well as aiding maintenance of those control valves (15, 17) in their closed positions thereby reducing the size and cost of the latching permanent magnets (25, 27). Air return springs for the control valves are formed by annular chambers (37) which are sealed by initial control valve motion away from their respective closed positions. Thereafter, the chamber size diminishes linearly, and the chamber pressure increases approximately linearly, with further control valve motion thereby providing a restorative force to the control valve which increases as the valve opens.

Abstract: The invention relates to a sawing and milling tool (1) for working primarily soft material, for instance wood. The tool includes a saw chain (20) composed of a plura­lity of links (21-23). The tool (1) includes a centre disc (10) of circular outer configuration. The saw chain (20) extends around the periphery of the centre disc (10) and a clearance or play is presented between the chain and the disc, such that the chain can be rotated relative to the disc when the disc is statio­nary. The chain links (21-23) have mutually different shapes and/or weights, such that when acted upon by centrifugal forces generated by rotation of the tool (1) the play or clearance is eliminated partially, so that the chain (20) is caused to accompany the centre disc in its rotation, as a result of frictional engage­ment between at least one chain link and the centre disc. The peripheral surface (12) of the centre disc (10) has formed therein a circumferentially extending guide groove (13) and the saw chain (20) includes guide links (23) which extend into the groove (13). Formed in the centre part of the disc (10) is a hole (11) by means of which the tool (1) can be mounted on a rotat­able spindle of, for instance, a hand-held machine. The inventive tool can be used as a saw blade and milling blade when working, for instance, wooden workpieces. In principle, it is not necessary to lubricate the tool, despite the presence of the saw chain. The tool also incorporates a slip-guard, which is activated automati­cally when the saw chain becomes jammed or when an excessively high feed-pressure is applied when using the tool.
