Abstract: In a system using the double absorption process for sulphuric acid manufacture, a single acid circulation system and a single cooler are employed. Acid from the exit of the air drying tower and final absorber tower are mixed in a common reservoir, while acid from intermediate absorber tower is discharged to a separate reservoir. Acid from the common reservoir is split between the intermediate and final absorber towers and product line. Acid from the separate reservoir is cooled and split between the drying tower and intermediate absorber tower. The circulation arrangement reduces the cooling to one relatively high temperature location and simplifies acid strength and level control. Only half of the bulk of the circulating acid has to be cooled and the effect of seasonal fluctuating temperatures in the drying tower is minimized.

Abstract: The method employs hydraulic motors (1), the angle of tilt of which is adjusted by an actuator (2) for the purpose of altering the capacity and hence the torque which can be transmitted. In addition, a restrictor (4), the aperture cross-section of which is adjustable, is inserted in the fluid feed. Control is effected in such a way that the angle of tilt for transmitting a specified torque is adjusted in an adjusting movement decoupled from the control of the speed, prior to the occurrence of a load torque, the control of the speed being effected exclusively by altering the energy supply to the hydraulic motor, whereupon, to maintain the working speed after the occurrence of a load torque, the control of the speed is effected taking into account in the control of the speed the actuating device for the adjustment, in particular the angular adjustment, of the hydraulic motor. <IMAGE>

Abstract: Single-compartment, self-erasing, solution-phase electrochromic devices, solutions of electrochromic compounds for use as media of variable transmittance in such devices, and electrochromic compounds for such solutions are provided. The devices of the invention are surprisingly stable to cycling between light and dark states, have continuously variable transmittance to light as a function of electrical potential applied across the solution in a device, and have transmittance that can be varied over more than a factor of 10, from clear to dark or from dark to clear, in several seconds. Thus, the devices are especially suitable as variable transmittance components of variable transmission light filters, including windows, and variable reflectance mirrors, including anti-glare rearview mirrors in automobiles. Also provided are improved variable reflectance mirrors, wherein transmittance of reflected light is varied by thermochromic, photochromic or electro-optic means and wherein the reduction in transmittance which is required to eliminate perceptible reflection of an object to the eyes of an observer is reduced by disposing the plane of the highly reflective surface of the mirror at an angle with respect to the plane of the surface through which light from the object enters the mirror.

Abstract: Data buffering apparatus having a synchronous input and output capabilities comprises a three stage system which synchronizes the incoming data stream with the memory input clock, buffers the incoming data stream and provides a variable delay for the data. The digital data stream from an input device is received by an input synchronizer (11) having its input clocked at the clock rate of the input device clock and its output clocked at a higher internal clock rate. The data is written into two FIFO buffers, a master (13) and a slave (15). The master buffer (13) controls the read and write addresses of both buffers, so that the write address of the buffers advances only when valid data is written into the buffers, and the read address advances only when data is read out of the buffers. The slave buffer (15) can be programmed with an offset in its read address, so it operates as a delay buffer. The data is read out of the buffers into an output synchronizer (17), having its input clocked at the internal clock rate its output clocked at the clock rate of the memory control.

Abstract: A piloted valve especially for manually switching hydraulic vehicle suspension units between hard and soft modes, and providing a third mode for very bumpy terrain. 
     A volume 8 (which may extend around the armature 9, 10), gradually fills up through a low-flow path 7A, to exert a downward pressure on a first flap 6. 
     A pilot channel 16 is opened by energising coil 12, whereon an armature in two parts 9 and 10 closes up, lifting conical needle 8. The first flap 6 then rises through fluid pressure acting from below, because the downward pressure is released through the pilot channel 16. This is the soft suspension mode, because import port 3 from the unit connects with output port 21 and a reservoir, via the now uncovered seat 18. The hard suspension mode exists when the valve is effectively closed. 
     The ultra-soft or emergency mode is set up by the vehicle wheel hitting bumps, or other high pressure shocks, when the soft suspension mode is already in existence. Sudden shocks or high pressure P1 at the input port 3 then increases pressure P3 directly via uncovered seat 18, and this pushes down final flap 22 against an initial high bias exerted by six radial springs 25 against an inclined annular surface 27. 
     A bypass path through 23 is then opened. The final flap has a hole 29 by which fluid passes in the soft suspension mode. But bypass path 23 is even faster, and the "shock" moade is therefore very soft.
