Filed: 1920-12-21
Abstract: 176,549. Osmosis Co., Ltd., Highfield, J. S., and Laurie, D. Northall-. Dec. 21,1920. Pottery materials.-A clay suspension obtained with an electrolyte, such as that resulting from the mining process described in Specification 135,277, is allowed to settle in a tank while the lower part of the material is maintained in a state of slow motion sufficient to prevent the formation of a solid deposit. The supernatant liquid is then drawn off, leaving a lower layer of creamy consistency which can be run out directly to a drier. The upper liquid may be passed to another settling-tank, where water and electrolyte are. added, and, after the separation of a fine clay, which can be dug out from time to time, it may be used again for the mining operation. Figs. 2 and 4 show two forms of suitable apparatus. The tank a, Fig. 2, has a rotary agitator b near the bottom and a vertically-adjustable siphon f for the discharge of the supernatant liquid. The stirring- device p, Fig. 4, consists of a rectangular frame with cross-bars. It is suspended on rods q and oscillated by means of a crank-shaft t. A modification is described in which the frame has wheels, which run on the bottom of the tank, and is oscillated by means of an endless band.

Abstract: 1,082,089. Combined osmosis distallation desalination. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Aug. 3, 1966 [Aug. 20, 1965], No. 35883/65. Headings B1B and B1X. Fresh water is obtained from aqueous salt solutions containing CaSO 4  e.g. sea water by passing such a solution through a first compartment of an osmotic cell in the other compartment of which passes a concentrated salt solution, at least a portion of which passes to a distillation apparatus, from which fresh water is removed and the concentrated solution returned to the second compartment of the osmotic cell. Membranes are preferably made from cellulose acetate, and the temperature of operation about 40 - 45C. The two solutions may flow either cocurrently or countercurrently through the osmotic cell. In the figure is shown an apparatus for desalinating sea water having a flash distillation unit 1, and an osmotic cell 2 with membrane 5. Sea water enters the system at 20, and together with recycled sea water, enters compartment 4 of the cell 1 at 8 and leaves at 9. There some of the concentrate goes to waste at 19 while the bulk is recycled by pipe 17 and pump 18. Concentrated aqueous solution enters compartment 3 at 6 and leaves at 7, the bulk of it being recycled via pipe 10 and pump 11 while a proportion is passed by pipe 12 to flash distillation apparatus 1, from which the distillate is drawn off at 14 and the concentrate is returned to pipe 10 via pipe 13. About 1% of the circulating solution is continuously bled off at 15, make-up solution being added at 16. The system avoids the formation of CaSO 4  scale in the flash distillation unit. Heat losses may be minimised by use of heater chargers between conduits 12 and 13 and between 19 and 20. Heaters may also be provided for conduits 12 and 20.

Title: Process for the manufacture of paper and paper-like webs
IPC: D21F9/02
Filed: 1960-10-21
Abstract: In the manufacture of paper or paper-like material, fibres, e.g. of wood and/or cellulose, are suspended in a gaseous medium and sprayed with a liquid binding agent, cooled whilst still suspended and then, with or without the addition of other fibres, e.g. cellulose or synthetic fibres, formed into a pulp with water and made into a web on a paper-making machine, the web being subjected to heat and/or pressure to effect bonding of the fibres, and shaped, if desired, e.g. in containers.  The bending agent, suitably a thermoplastic polymer, cellulose derivative or pre-condensate of a phenoplast or aminoplast, is liquefied by heating and/or solvent addition and solidified on the fibres, whilst these are steel suspended in the gaseous medium, by cooling and/or solvent evaporation.  To render them easily wetted by the binder the fibres may be pre-dried and/or impregnated, and the coating with the binder may be further assisted by utilizing a high voltage eletric field in the spraying chamber. The final sheets or shapes may be further lacquered or provided with covering layers.  In an example wood fibres are sprayed with an equal amount by weight of a 50% solution of a polyacrylic mixed ester in benzene/ethyl acetate, at 50 DEG C. and the coated fibres mixed in a 1 : 1 ratio with uncoated wood pulp fibres to form the aqueous pulp for the web; in a further example cellulose fibres are sprayed with a solution of acetyl cellulose in acetone and the coated fibres mixed with synthetic fibres to form the aqueous pulp for the web.

Title: Method and apparatus for chemical analysis
IPC: G01N33/62
Filed: 1972-08-03
Abstract: 1395223 Biological measurements BECKMAN INSTRUMENTS Inc 3 Aug 1972 [6 Aug 1971] 36271/72 Headings G1A and G1N In an arrangement for determining the concentration of a component in a sample, e.g. urea in blood, the output of a sensor monitoring a characteristic e.g. conductivity of a solution of the sample when added to a reagent and representative of the component is differentiated and the differentiated value obtained as a measure of the concentration after a predetermined time from the introduction of the sample into the reagent. In the arrangement of Fig. 7 the A.C. conductivity of the fluids in sample cup 21 is monitored using a pair of A.C. energized electrodes and the amplitude modulated output signal is demodulated at 25 to provide a D.C. output signal which is differentiated at 31. In order to obviate the effects due to the jump in conductivity when the ionic blood serum sample is injected into the sample cup 21 the differentiator 31 is inhibited for a time long enough to permit the transient jump to disappear and permit thorough mixing of the sample. At the end of this period the inhibition signal is removed and the output of the differentiator 31 rises to the actual signal level of the differentiated A.C. conductivity due to ionic ammonium carbonate formed by urea in the blood sample reacting with the enzyme urease in the sample cup 21, and then falls with the reaction rate. The signal peak obtained is thus proportional to the urea concentration in the sample and is sensed and held in rate measuring circuit 40. The inhibition of the differentiator 31 may be achieved as shown by applying the output of the demodulator to a rate sensing circuit 35 which senses the jump in conductivity and supplies a signal to a time delay circuit 37, the latter generating a control signal a characteristic of which changes after a predetermined time to operate the differentiator. Alternatively the output on line 26 may be applied to a conductivity level sensing circuit which senses the jump in conductivity and generates a signal to be applied to the time delay means. The rate measuring circuit 40 may be a sample and hold circuit, Figs. 5 and 8 (not shown) which is operated by a signal from the time delay 37 after the differentiator has been operated. In another arrangement the rate measuring circuit 40 samples the differentiator output at a time later than the rate peak, Fig. 6 (not shown). Sample chamber, Fig. 9 The conducting reagent is supplied through one side of passage 63, and passageway 62 into the chamber 59 provided with a magnetic stirrer 70. The sensor 22 is in the form of a cylinder which screws into aperture 75 and carries two planar electrodes. The end of the cylinder may be spherical in which case the electrodes are D-shaped on the surface with the straight portions parallel, Figs. 10, 11 (not shown). The sensor may be a spectrophotometer.

Filed: 1946-12-10
Abstract: 630,888. Circuits for electron multipliers; valve modulating circuits. JONES, S. Dec. 10, 1946, No. 36440. [Classes 40 (v) and 40 (vi)] In an electron multiplier circuit, particularly for amplifying small D.C. potentials, a source of alternating modulating potential is applied to two dynodes, in push-pull, an output potential appearing across a circuit in the anode lead of the multiplier tube, tuned to the third harmonic of the alternating potential. The modulation components are additive, whereas the components fed to the output by capacitive coupling tend to cancel. The output signal may be rectified to give an amplified version of the input. Light, incident upon the photoelectric-cathode 4 causes the emission of electrons which pass to the dynodes 6 ... 14, an increased current flowing to the final anode 5. A source 30 of A.C. feeding dynodes 10, 12 modulates the electron stream, the circuit 27 being tuned to the third harmonic to pass a signal modulated according to the level of the light incident upon the cathode 4. Specification 531,219 is referred to.

Abstract: 793,827. Motor driving arrangement. MAWDSLEY'S Ltd. Dec. 13, 1956 [Dec. 20, 1955], No. 36521/55. Class 35. A motor rotor slides axially by magnetic attraction when energized, thereby engaging a clutch, the driven member of which is on an output shaft which does not move axially, and a brake is applicable to the output shaft by spring action. The stator and rotor cores are toothed at 18, 19 and in Fig. 1 the upper half shows the clutch engaged and the lower half the position of the rotary parts when the motor is de-energized. Movement of driving clutch member 34 to the left engages driven clutch member 37 and causes it to slide axially on the drum 32 on driven shaft 29 against the pressure of brake spring 39 sufficiently to free the flange 38 on the clutch member 37 from the friction surface 42 on brake member 40. On de-energization of the motor, spring 20 urges the rotor to the right, releasing the clutch so that the brake is not operative on the motor. The driven shaft 29 is hollow and splined internally to receive the shaft of the driven machine or could be solid and supported on the end of the motor shaft by means of an additional bearing disposed in the hollow hub of drum 32 and this space could also house the spring for returning the rotor. As an alternative to the brake applying spring 39 shown, there could be a number of springs spaced at intervals around the flange of hub 32 or the driven clutch member could take the form of a resilient member 90, Fig. 6, carried by hub 32 and carrying friction material to engage both the driven clutch member 34 and brake surface 40.
