Title: Improvements in or relating to instruments for measuring moisture content in wool and other substances
IPC: G01N27/04
Filed: 1946-04-15
Abstract: 625,024. Resistance measurements ; moisture content measurements. MARCONI INSTRUMENTS, Ltd., BROCKELSBY, C. F., and TODD, W. A. H. April 15, 1946, No. 11544. [Class 37] The resistance R of certain hygroscopic materials, notably wool, cloth, timber and tobacco, varies at constant temperatures substantially in accordance with the expression log. R= A+B/m<SP>1</SP>/ 3  , wherein A and B arc constants depending on the material and the structure of the electrodes between which the material is placed for measurement and m is moisture content. If the material to be tested is a conductor at zero moisture content the relation is log. G - G 0 =A + B/m, where G is total conductance (i.e. with moisture present) and Go is inherent conductance. A moisture measuring resistance network according to the invention is so designed that adjustments therein may be effected to satisfy the constants A and B and such that one moisture scale serves for a range of materials. The moisture meter produces an indication proportional to log. R-A or in the case of inherent conductance log. (G-G o )-A. It is preferred to avoid maintaining constant temperature and under these conditions the relationships are log. R=A+B/Tm1/3 and log. G-G 0 =A+B/Tm1/3 where T is absolute temperature ; the indication is then also proportional to T/B. A preferred embodiment is a double bridge network, Figs. 2 and 2a (not shown) which is so constructed as to wholly electrically satisfy A and B and provide automatic correction for T and is as disclosed in Specification 625,023. Fig. 1 shows an alternative electro-mechanical arrangement in which the test specimen between its electrodes constitutes the arm R1. The arm P1 is equal to the third arm Q1 multiplied by 10A and the balance arm S1 is a logarithmically variable resistor. The adjustment shaft of S1 drives an indicating pointer N through a variable velocity drive VR which is set to the value B. The scale MS is moved automatically or manually so that it is displaced in proportion to the temperature T. A suitably shaped cam CD is interposed in the drive to give a log. m scale. If there is inherent conductance Go in R1, a balancing resistance is shunted across S1. Self-balancing bridges may be employed.

Title: Process for the enrichment or other treatment of phosphated chalk and other substances with a basis of carbonate of calcium or lime
IPC: C05B11/02
Filed: 1924-05-10
Abstract: 224,468. Bernard, G. May 10, 1924. Phosphates; calcium hydrate and carbonate.-In a process for enriching phosphated chalk or other materials with a basis of carbonate of calcium or lime, the calcium salts are converted to hydrate of calcium which is separated from the insoluble materials by using, as a solvent, a sufficient quantity of water to dissolve the hydrate. The material is first baked in the usual way and then contains calcium phosphate with impurities and quick lime; the last is converted into hydrate by the addition of water. The material is then placed in the reservoir 1 above a filter consisting of filtering material 3 such as hair or plates 2; the upper plate is covered by fine copper wire gauze. Circulating water is supplied through the conduit 5, and perforated tubes 6 conduct compressed air into the reservoir to agitate the charge. A pump 8 reduces the pressure below the filter and assists the flow of water charged with lime, through the receiver 9 and the pipe 10 to the tank 11. Baffles 14, 15 are arranged in the tank, and a perforated pipe 17 opens into compartments below a false bottom consisting of perforated plates 12 and porous material 13. The pipe 17 is supplied with carbonic acid gas from the washing tower 20, which is in communication with the furnace used for the preliminary baking of the material. The gas passes up through the lime water, and any remainder passes through the pipe 26 and is re-circulated by the pump 19. The liquid passes through the pipe 21 to a series of decanters 22. where the carbonate passes through the pipes 28 and the water is passed by the pump 27 through the pipe 5 to the reservoir 1.

Title: Measuring out apparatus for liquids
IPC: G03D3/06
Filed: 1960-04-01
Abstract: 939,410. Delivering measured quantities by volume. AGFA A.G. April 1, 1960 [April 10, 1959], No. 11646/60. Class 106 (5). [Also in Group XXIX] A liquid dispenser comprises a measuring chamber 29 having an upper inlet 20 and a controllable delivery valve 40 at its lower end, and a float 30 guided for vertical movement in the chamber between a lower valve seating 31 located above the valve 40 and an upper abutment 32, the arrangement being such that, on opening the valve 40 with the float in contact with the abutment, liquid contained in and supplied to the chamber passes downwardly through the latter causing downward movement of the float on to the seating 31 whereby a metered quantity of liquids is delivered, and, after closure of the valve 40, liquid within the chamber causes upward displacement of the float to engage the abutment. The clearance between the float and the measuring chamber is such that the liquid can pass through the clearance at a low speed only. Liquid, for example regenerating liquid for supply to photographic processing tanks, is introduced into the chamber 29 at a constant rate through supply pipes 23, 20 and the float rises until it contacts the abutment 32, and further liquid entering the measuring chamber collects above the float. Upon the opening of the delivery valve 40, the float travels in the chamber at the same speed as the surrounding liquid and, when it reaches the valve seating 31 cuts off the discharge of the chamber. The abutment 32 is mounted on a wire 33 held tightly in a predetermined position by a compressible rubber ring 35 and protected at its upper end by a cap 38. To control the quantity of liquid dispensed, the measuring chamber, which may be of glass or other transparent material, is provided with a scale which co-operates with a mark 51 on the float, the height of the float being adjusted by the abutment 32. The quantity may further be varied by interchanging both measuring cylinder and float, this interchange being carried out by sliding the measuring chamber upwards over a nozzle 24a which is sufficiently long as to allow the lower end of the measuring chamber to become detached from the lower nozzle 25a. The valve 40 is solenoidoperated and energized through windings 27 which are connected through a plug 49 to a time switch arranged to open the valve for short periods at predetermined intervals.

Abstract: 1,044,103. Circuits employing bi-stable magnetic elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 22, 1965 [April 6, 1964], No. 12004/65. Headings H3B and H3T. In a data store in which bi-stable devices, e.g. magnetic cores, are arranged in pairs of rows 1, 2 and each pair is associated with a common conductor, a balancing transformer 3 has its primary and secondary windings connected one to each half of the conductor, a driver 4 is connected to the conductor, and a differential amplifier 5 is connected between the halves. This arrangement of transformer 3 causes equal currents to flow through each half of the conductor. The circuit forms part of a threedimensional store in which cores are selected by energizing X and Y windings (not shown) and the bit to be stored is determined by the presence or absence of an inhibit current. During writing, diodes 6, 8 are reverse biased equally and inhibit currents do not act upon the sense amplifier 5. When the inhibit current is switched off by removing the input from transistor 4, the negative voltage excursion in the inhibit-sense conductor forward biases diode 10, through characteristic impedances 11, 12 so that transistor 13 is forward biased and prevents the collector voltage of transistor 4 rising excessively. During read-out, by coincident drive currents in the X and Y lines, the voltage induced in one half of the conductor or the other is insufficient to back bias diode 6 or 8 and is therefore applied to one half of the differential amplifier. In modified circuits either the driver is connected directly to the junction of the two halves of the conductor, the sense amplifier is connected between the halves at the opposite end, and the two transformer windings are connected at one end through diodes to the two halves of the conductor and at the other end in common to earth (Fig. 5, not shown); or the driver includes two transistors supplying inhibit pulses simultaneously through respective transformer windings and diodes to the two halves of the conductor, and the amplifier is connected across a resistor joining the two halves of the conductor (Fig. 6, not shown), one transistor being controlled directly from the input and the base of the second transistor being connected directly to the emitter of the first and through a resistor to its own emitter.

Abstract: 772,318. Bobbin coupling means. VEB SPINN-UND ZWIRNEREIMASCHINENBAU KARL-MARX-STADT. April 27, 1955, No. 12204/55. Class 120 (2). Means for coupling a bobbin to a textile spindle comprises a ring rotatably mounted on the spindle, link means fixed to the ring and carrying weight carriers which carriers have rockably fixed thereto centrifugal weights, the arrangement being such that during rotation of the spindle the centrifugal weights are pressed against the inner wall of the bobbin. In the arrangement shown a rear bearing carrier 28, a front bearing carrier 29, a cover 34, a casing 31, and a sleeve 30 are all connected by bolts 32 and are turnably mounted on a stub shaft 33. Between the rear bearing carrier 28 and the jacket 31 and between the front bearing carrier 29 and the cover 34 there are mounted rings 23 for carrying the coupling mechanism. This mechanism consists of a ring 11 which is free to turn and pairs of links 12 fixed to the ring 11 by pivot pins 26. The links 12 are connected at their outer ends by pivots 25 with centrifugal weight carriers 13. These latter members are mounted by means of bolts 14 on the ring 23 and carry the centrifugal weights 16 by means of bolts 15. The weights 16 have mounted in their ends compression springs 20 which are arranged to press the portion 18 of the weights against the inner wall of the bobbin 17 when the latter is in position. Pins 27 and 35 are provided on the ring 23 and the ring 11 and arranged between these two pins is a spring 24. This spring acts on the ring 11 to keep the centrifugal weights withdrawn when the bobbin support is at rest. Upon rotation of the bobbin support the centrifugal weights 16 move outwards against the action of the spring 24 and the portions 19 of the weight 16 also contacts the inside of the bobbin 17 and thus firmly holds it in position.
