The preferred calcium salt is CaCl 2 . Any MgSO 3  in the initial sludge may be oxidized to MgSO 4  before carrying out the extraction. The resulting Mg(OH) 2  may be calcined to MgO. Addition of the Ca salt and/or the oxidizing agent may take place in the scrubber. Reference has been directed by the Comptroller to Specification 1,178,109.
Patent GB-670626-A (GB)
Abstract: 670,626. Blasting cartridges. UERSCHEL, C. F., SLICK, E. F., COX, J. J., GRANT, G. W., DENMAN, L. G., SELLIGSON, A. A., BAXTER, A. J., WRIGHT, B. N., GILBERT, 1. O., and PINCUS, G. G. Oct. 21, 1948. [May 26, 1948] No. 27363/48. Class 9 (i). [Also in Group XXXVIII] An explosive charge assembly 10 for seismic prospecting comprises a charge 11 and a shield 12, the charge being in the shape of a disc with a plane outer surface 13. A blasting cap 14 arranged centrally of the disc has leads 15 connecting it to a firing device. The charge is preferably a high explosive such as TNT or RDX. The shield 12 is a paperboard container 18 filled with a granular mass 17 such as sand and extending beyond the peripheral edge of the explosive. The charge may be suspended by cords 74 from a support 70 with the flat surface 13 towards the earth, Fig. 11. On firing the charge, the resultant explosion wave is directed downwardly and after reflection from substrata is received by a geophone G at the surface, Fig. 8. A 1 Jb. charge, diameter 9 inches and thickness 5/16 inches, fired at a height of 15 feet gave reflections from depths exceeding 10,000 feet. Several charges may be fired simultaneously the charges being spaced to give a composite wave-front. To produce a focussing effect, the central charge may be above the plane of the other charges. To increase this effect, the outer surface 13 of the charge may be concave and the individual charges be placed to lie on the surface of a sphere whose radius is the radius of curvature of the charges. The charges may be tilted so that the wave is focussed towards a remote geophone G, Fig. 8, The support 70 is 15 to 20 feet long and telescoped over a stake 72 inserted in the ground. The charge assembly is suspended from an adjustable arm 73. By adjusting the relative lengths of the suspension cords 74, the charge can be tilted to the desired angle. To take soundings over water a floating buoy may be used to support the charge at the required height. Specification 670,625 is referred to.
Patent GB-698023-A (GB)
Abstract: 698,023. Electric indicating systems. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AERONAUTIQUES (O.N.E.R.A.). Dec. 6, 1951 [Dec. 11, 1950; March 5, 1951], No. 28642/51. Class 40 (i) [Also in Group XL(b)] In an infra-red gas analyser of the type in which two beams of infra-red radiation pass, one through a chamber containing the gas under analysis and the other through a comparison chamber and each beam then passes through a succession of chambers each of which contains one of the components of the mixture, detecting chambers and sample chambers are arranged alternately, the sample chambers being of different lengths thus making it possible to use the optimum sample length for each component to be detected. As shown two beams of infra-red rays from sources 1, 2 pass through a chamber 6 containing the gas under test and a comparison chamber 16 respectively. The latter chamber contains an inert gas. Each beam then passes into one of the detector chambers 7, 14 containing the first gas to be detected. The differential expansion of the gases in these two chambers is detected by a diaphragm condenser 20. The length of the first sample chamber is the optimum for the gas being detected. The beams then pass into further sample chambers 8, 17 whose length is such that, together with the length of the first sample chamber 6, 16, the path length is an optimum for the component to be detected in chambers 9, 15. This is repeated for as many pairs of sample and detector chambers as there are components in the gas. The gas under test circulates through all the sample chambers through a pipe 12. The fixed plate of each diaphragm condenser 20, 22 is connected direct to an amplifier A, while one of the moving plates is connected to the amplifier supply by a switch 26 the remainder of the moving plate being earthed. Compensating for density changes, Figs. 3 and 4. To compensate for changes in density of the gas under test the milliameter 32 is shunted by a bridge circuit P containing a resistor Rv responsive to the changes in density of the gas. Since however such a resistor is not capable of correcting the meter reading when the meter zero does not correspond to zero density an auxiliary voltage V2 is applied to the diagonal of the bridge which corrects the meter zero reading, resistor Rv correcting for the density changes. A density sensitive resistor is shown in Fig. 4. The gas under test is circulated through an outer vessel 105 the pressure of this gas acting through a calcined gas plate 111 on one end of a mercury column 109. A gas in an inner vessel 106 acts through a similar plate on the other end of the column. As the mercury rises or falls with pressure or temperature changes in the gas it alters the effective length of wire Rv of platinum iridium. Specification 655,713, [Group XL(b)], is referred to.

Abstract: A container for vaporisable liquids which comprises a peripheral wall 2, a base 1 and a flexible membrane 3 anchored at its periphery to the wall at a position above the base and forming with the wall and base an enclosure of variable volume and a liquid of greater density than the liquid to be stored in the enclosure on the side of the membrane remote from the enclosure which liquid will cause the membrane as the enclosure is filled to form a skirt depending from a central region of the membrane, the skirt forming with an outer marginal part of the membrane a recess filled with the denser liquid which will keep the skirt above the peripheral anchorage away from any static surface which surrounds the skirt with which the skirt would otherwise make frictional contact as the liquid level in the enclosure varies. The vessel may be a ship or a static storage tank and the greater density liquid may be a further stored liquid. Filling and emptying the tank of the lower liquid is effected from below a perforate batten 9 adjacent the tank base 1 and which slopes away from a central peak 9a. <IMAGE>

Title: Apparatus for loading or unloading pallets
IPC: B65G1/00
Filed: 1979-01-29
Abstract: Apparatus for loading discrete loads, such as casks, onto a pallet comprises a frame 10 mounted on rollers 18 for rotation about a horizontal axis, a pallet conveyor 42 on which an empty pallet 40 can be fed to a roller platform 26 on the frame, retractable fingers 30 for supporting the pallet as the frame 10 is rotated through 180 DEG , and a load support platform 46 positioned, after the frame has been rotated through 180 DEG , to receive loads fed from an infeed conveyor 62. The load support platform 46 is movable towards and away from the roller platform 26 by means of a jack 56 acting through toggle linkages 60, so that the loads on platform 46 can be lifted to engage the pallet 40 suspended by the figures 30. The loads are thus clamped between the platform 46 and the pallet 40 as the frame is rotated back to its original position. The load platform 46 and pallet supporting fingers 30 are then retracted and the load pallet discharged onto a conveyor 44. The sequence of operations can be reversed to remove loads from a pallet. <IMAGE>

Title: Binary multiplier circuit including coding circuit
IPC: H03M7/00
Filed: 1979-04-05
Abstract: A binary multiplier circuit wherein the product is expressed in coded form as soon as the linear (or non-coded) product is produced. When a twelve-bit binary number in a register 10 is multiplied by another twelve-bit binary number in a register 12 a twenty-four bit binary number is produced in an accumulator register 15. The twenty-four bit product can be coded into an unsigned seven-bit binary number ( mu -255 code) as follows. The number 33 x 2<11> in binary form is preset in accumulator register 15 which at the end of the multiplication contains an augmented product. The number of leading zeroes in the augmented product is counted by a counter 23 which counts clock pulses and is reset by each 1 fed to accumulator register 15, and the base-minus-one complement of the count is formed by inverters 32, 33, 34 and used as the three most significant bits of the coded product. The four next most significant bits of the augmented product, after the most significant logic 1, are, at the end of the multiplication, stored in a latch 26, which is loaded by each 1 fed to accumulator register 15, and four least significant bits of the coded product. A sign bit for the coded product may be supplied at 37. <IMAGE>
