Title: Coagulation timing apparatus and method
IPC: G01N33/49
Filed: 1971-04-19
Abstract: 1306915 Measuring blood clotting time BIO/DATA CORP 19 April 1971 [13 April 1970] 26956/71 Heading G1A In an apparatus for measuring the coagulation (clotting) time of blood plasma, the transmissivity of the sample is measured to develop a corresponding electrical signal which is differentiated and the time varying part of this differentiated signal compared after a preset blanking period with a reference level in a difference amplifier, timing being stopped when the level is exceeded. As shown in Fig. 1 light from an incandescent lamp 16 is passed through the blood sample, which has previously been mixed with an oxalated or citrated anti-coaglant. On addition of a reagent to provide coagulation, timing is started on counter 78. The signal from photo-resistor 18, is filtered of noise and hum by resistor-capacitor network 24, 26 and then differentiated by circuit 28-38. The low amplitude differentiated signal is amplified by operational amplifier 36 and its time varying component passed by circuit 50, 54 applied to the face of transistor 56. During the first nine seconds of the timing operation, the base of of transistor 56 is clamped to earth by means of blanking circuit 90 saturating transistors 80,82 for this time. This avoids circuit transients, produced by the initial turbulence when the reagent is added to the blood plasma, which may cause fake measurements. Transistor 56 forms part of a differential circuit at the other side of which transistor 58 provides a reference voltage at its base. This can be adjusted according to the reagent used by changing switch 100. When the reference level is exceeded, transistor 64 biases transistor 74 into a conducting condition to stop counter 78 via its input flip flop. In order to modify the reference level set in the difference amplifier to allow for the fact that at longer coagulation times the signal amplitudes are lower, the reference voltage at 58 is derived via the counter and is reduced in step fashion with time, which can be smoothed by a capacitor, Fig. 5 (not shown)

Abstract: 974,095. Thin film magnetic storage circuits. PHILIPS ELECTRONICS & ASSOCIATED INDUSTRIES Ltd. July 17, 1962 [July 20, 1961], No. 27432/62. Heading H3B. In a storage matrix utilizing thin magnetic  films of conductive material the state of a core is read by noting the change in a current which flows, from a constant voltage source, through all elements of a column when the magnetic field of each element of a row is rotated through 45 degrees. In the embodiment shown, information is written into the matrix by selecting the row and column conductors, 1, 2 or 3, and 4, 5 or 6 respectively, and passing currents through them to rotate the magnetic field of the selected element through 80 degrees. The conductor 18 is then pulsed with a current of the correct polarity to set the selected element to the desired state. To read out information the current source 25 is switched on to the conductor 23 connecting the elements of the selected column. A row conductor is then pulsed to rotate the field of the magnetic elements through 45 degrees. The magnetic field of the element it is desired to read is then parallel to or at right angles, depending on the information stored, to the direction of the current flowing through the element. The change in current produced by the change of resistance is detected by transformer 26 which is connected to sense amplifier 21. To eliminate outputs when switching the current source 26 on and off two elements per bit are provided and set to opposite states to store information. The switches 24 are preferably pulse-controlled electronic switches. A three-dimensional matrix may be constructed by combining several of the matrices described and the column selecting switch and row windings may be common to corresponding columns or rows of all the planes.

Title: A process for the regenerating cation exchange resins used in water treatment plants
IPC: B01J49/00
Filed: 1963-07-16
Abstract: Cation exchange resins used in water treatment plants may be regenerated by a process wherein the resin is regenerated by a monobasic acid which is subsequently distilled with a polybasic acid or an acid salt of a polybasic acid, the strength and amount of the polybasic acid being such that it expels the monobasic acid from its salts, the monobasic acid being chosen to have a volatility above that of the polybasic acid. Monobasic and polybasic acids exemplified are hydrochloric acid (which may be obtained by distilling sodium chloride and sulphuric acid) and sulphuric acids; also mentioned are nitrous, nitric, acetic and propionic acids; pyrosulphuric, chromic and phosphorus acids, and acid salts of phosphorus.  Acids containing impurities may be utilized, for example hydrochloric and sulphuric acids containing chlorine, arsenic, organic substances, iron and salts of other metals.  When the more volatile acid is hydrochloric acid, the distillate fractions of low acid content can be used to produce demineralized water for example from sea water.  Sea water is added to the regenerating acid and the first distillate fractions are run through an anion exchange bed. This procedure can be utilized for regeneration using parallel or countercurrent flow, and when spent resin is removed from the filters for regeneration. There is reference to using the process of the invention for removal of ferric or aluminium ions from the resin.ALSO:Cation exchange resins used in water treatment plants may be regenerated by a process wherein the resin is regenerated by a monobasic acid which is subsequently distilled with a polybasic acid or an acid salt of a polybasic acid, the strength and amount of the polybasic acid being such that it expels the monobasic acid from its salts, the monobasic acid being chosen to have a volatility above that of the polybasic acid.
