Title: Gaseous sulfur dioxide absortion system
Inventor: CLEMENT JOHN LLOYD
IPC: C01B17/60
Filed: 1969-12-04
Abstract: 1285934 Treating gases with liquids BABCOCK & WILCOX CO 4 Dec 1969 [10 Dec 1968] 59367/69 Heading B1R [Also in Division C1] In a process for absorption of SO, from a flue gas using an aqueous Mg(HSO 3 ) 2 -MgSO 3  absorbent, the gas is contacted with the atomised absorbent solution in a plurality of absorption zones, gas and liquid from each zone are separated, the major part of the liquid being recycled to the zone while the remainder is passed to the next zone in countercurrent to the gas flow, liquid is withdrawn from the first zone (in the direction of gas flow), and a compensating amount of makeup water is added to the system, being distributed between the zones in such a way as to maximise the efficiency of the absorption in the system and in particular, that in the last zone. Magnesium hydroxide slurry is also added to each zone at such a rate as to maintain the highest possible concentration of MgSO 3  without causing precipitation. The invention is illustrated by reference to treatment of flue gas containing 1% by volume of SO 2  from incineration of waste liquors in a pulp process to give a liquid in the first zone containing 4% SO 2 , which is returned to the process as cooking liquor. In each of three absorption zones 12, 27 and 36 the gas is contacted in a venturi scrubber 18, 30, 38 with the atomised absorbent. Gas and liquid are separated in the gas turning spaces 21, 31, 40 and the gas passes to the next zone by ducts 26, 32 while the liquid is partly recycled by lines 17, 35, 44 and partly passed to the preceding zones by lines 45, 46 or withdrawn by line 29. Magnesium hydroxide slurry is added through lines 53, 54, 55 and makeup water through lines 48, 50, 51. The best results are obtained by adding about 40-55% of the water to zone 36 and the remainder to zone 27.

In the production of ceramic tiles and drying and/or bisque firing is carried out in a tunnel kiln with the tiles stacked substantially vertically in saggers at a distance of at least 7 mm. from one another. Tiles from automatic moulding presses 1 and 1<SP>1</SP> are carried by conveyer belt 3 to a stacker 5 which loads them into saggers 7 from whence conveyer belt 6 carries them through a device 8 which turns the saggers on a horizontal axis through 90 degrees and then to a truck loading station 7R. The loaded truck 10 passes through a drying and biscuit firing tunnel link 11 to station 7R<SP>1</SP> where the saggers are placed again on conveyer 6 travelling then to an automatic unloading station 14. Empty saggers return on conveyer 6 and a conveyer belt 15 moves the tiles first through a glazing tunnel 16 and then to stacker 5<SP>1</SP>. The initial process is repeated with kiln truck 18 passing through a glazing tunnel kiln 19 and the glazed tiles are unloaded at station 14<SP>1</SP>.

To compensate for asymmetry of the axle, which can prevent cancellation of the effects of bending, the load cell is formed with similar asymmetry, e.g. by tapering the member 47, or using bosses 48c, 49c of different lengths or thicknesses or material, etc. The strain gauges may alternatively comprise crossed members 39 Fig. 2 located on a horizontal diameter, at 45 degrees to the neutral axis.
Patent GB-701787-A (GB)
IPC: G05B19/06
Abstract: 701,787. Casting-machines. SCHULTZ DIE CASTING CO., and TRIGGS, W. W. July 8, 1948, No. 15416/50. Divided out of 707,633, [Group XL(a)]. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 11, 1949.] Class 83 (i). [Also in Group XL(c)] The operating sequence of the die-casting machine described in the parent Specification is controlled by an electronic valve circuit comprising four gas-filled valves each having a time delay network in its grid circuit. The sequence of operation is initiated by pressing a starting switch 640. This operates relays R402 and R406 causing the dies to close and to operate a relay R566 the latter interrupting the main bias circuit (shown in black lines), to valves 1 ... 3 leaving an auxiliary supply (shown in dotted lines), connected to valves 2, 3. Valve 1 accordingly fires after its time delay, operating a relay R510 to start a slow metal injection into the dies and break the auxiliary bias circuit to valve 2 which, after its time delay fires, operates relay R596 to start the rapid metal injection. Further contacts of relay R596 break the auxiliary bias circuit to valve 3 which accordingly fires after its time delay operating relay R600 which connects a further bias circuit to valves 1, 2 to cause them to extinguish and thus cut off the metal injection. Contacts of relay R600 break the bias circuit to valve 3 to prevent it extinguishing when relays R510 and R596 release and a further contact breaks the main bias circuit to valve 4. This valve fires after its time delay, operating relay 412 which opens the dies and re-establishes the main bias circuit to all valves. A detailed circuit diagram, Fig. 1 (not shown), is described and block diagrams, Figs 3 ... 6 (not shown), illustrate the circuit conditions applying immediately after each valve has fired.

Title: Electronic timepieces
IPC: G04G9/08
Filed: 1978-06-15
Abstract: A digital electronic timepiece having a multi-digit digital display for displaying the time count in a time counter which receives a divided down time signal from a time base signal generator. At least one settable time counter for storing a count corresponding to a desired time period is provided which is receptive of a time signal for decrementing the count thereof to zero. A plurality of display driving signals, each corresponding to one digit of display are generated wherein the display signals of successive digits are phase delayed with respect to each other and the frequency thereof is sufficiently low to produce visible flickering of display. Upon the sensing of the zero count in the timer counter, the display which is normally non-flickering, is driven with the display driving signals to produce a sequential flickering of the digits of the time display to provide a visual indication of the lapse of the desired time period.

Title: Device for Simultaneous Diffusion and Tempering of Fluids
IPC: A61M5/44
Filed: 1979-01-29
Abstract: Diffusion (including mixing) is carried out between first and second fluids whilst at least one of those fluids is substantially simultaneously tempered by a third fluid separated therefrom by a heat permeable membrane. This membrance can be semi-permeable but usually is fluid- impermeable. Preferably, the first and second fluids are separated from each other by a semi-permeable membrane across which the first fluid or a component thereof diffuses into the second fluid. In a preferred device pairs of the heat-permeable membranes 3 alternate with pairs of the semi- permeable membranes 2. The third fluid C is passed between the heat- permeable membranes in each respective pair thereof whilst the first fluid A is passed between the semi- permeable membranes in each respective pair thereof. The second fluid B is simultaneously passed over the outer surfaces of both sets of membranes. In a further embodiment, the semipermeable membranes 3 are omitted. The invention has particular application to oxygenating blood (second fluid (using air (first fluid) whilst tempering the blood with water (third fluid). <IMAGE>
