Title: Formation of adherent precipitates on surfaces immersed in liquids
IPC: G01N27/04
Filed: 1974-02-18
Abstract: 1433962 Electro-physical measurement MAGNA CORP 18 Feb 1974 [26 Feb 1973]  7250/74 Heading G1N The formation of scale on an electrically conductive surface immersed in a liquid is determined by measuring its contact resistance with an engaging electrode. The scale may be e.g. boiler scale or wax deposit in a pipe-line, and a heating or cooling coil (77) may be provided Fig. 3 (not shown). The electrode may be a roller engaging a rotating cylindrical test surface Figs. 2, 3 (not shown), or may periodically retract and later re-engage the test surface Fig. 1 (not shown). The liquid may be an ionic conductor in which a higher contact resistance is detectable (due to the "electro-chemical overvoltage") with the onset of scale, or an insulating liquid (oil) in which the circuit is broken when scale separates the contacts. The choice of electrode material according to the ionic liquid can increase sensitivity, and it may be chosen to provide "battery action" so that the measuring circuit is self-powered. The test surface may be cleaned by a scraper or periodic polarity reversal.

Title: Radiation detectors
Inventor: MUNDAY CHARLES WALTER
IPC: G01N21/37
Filed: 1955-03-12
Abstract: 786,516. Infra-red radiation, detecting. DISTILLERS CO., Ltd. Feb. 23, 1956 [March 12, 1955], No. 7305/55. Class 40 (3). A detector for the determination of the energy content of cyclically interrupted radiation of a certain frequency comprises two adjacent chambers 1, 3, at least one of them having a wall, e.g. 2, transparent to the radiation, and a passage 4 connecting the two chambers. Means are provided for filling the chambers with a gas which absorbs energy at the frequency concerned and the volume of the connecting passage is made extremely small, e.g. one millionth part of the volume of one of the chambers. An electrically heated element 7 is mounted in the passage and means are provided to measure the variations in temperature of this element due to the cooling effect of the gas flow past it resulting from pressure variations caused by the reception of radiation intermittently by one or both chambers. Where the capacity of the chambers, which are preferably equal in size and shape is from two to three cubic inches the passage may be rectangular in cross-section and 0.4 inches long by 0.003 inches wide with a depth of 0.003 inches. Square or circular section passages may also be used. The element should have a heat capacity approximately equal to that of the gas immediately surrounding it and low compared with the heat capacity of the passage as a whole. It is preferred to determine its temperature variations by resistance thermometry and it should therefore have a high resistance temperature variation. Suitable elements comprise nickel oxidecobalt oxide flakes and platinum or nickel wires. A platinum wire 3Á in thickness, 0.4 inches long, and supported symmetrically in the passage is suitable for a passage of the dimensions given. It should be under sufficient tension to maintain it taut. If the variations in resistance are to be detected by means of a bridge circuit a second and identical element 8 not exposed to the gas flow is mounted in one of the chambers and shielded from radiation. This then forms a reference arm of the bridge. A shield or shields are also necessary to prevent radiation penetrating the connecting passage and one such shield is shown at 5. A second passage of long time constant compared with the first may be provided between the chambers to stabilize the instrument against external fluctuations in temperature. Instead of a bridge-type of detector circuit (Fig. 6, not shown), the element 30 (Fig. 11), may be connected in series with a D.C. source 28 and an isolating resistor 29. An alternating current amplifier and indicator can then be coupled across it via a capacitor 39. The detector is suitable for use in a chopped double beam infra-red gas analyser of the general type described in Specification 683,952.

Title: Improvements relating to prepayment mechanisms for electricity meters
IPC: G07F15/00
Filed: 1924-03-22
Abstract: 234,227. Chamberlain & Hookham, Ltd., and James, S. March 22, 1924. Electricity, supplying by meter.- After prepayment a cam d, Fig. 2, is rotated and depresses a lever e against a, spring, a pin h on the lever moving idly past a spring-controlled pawl i on a pivoted switch g. On the return of the lever e under the action of its spring, the pin h engages the pawl i and moves the switch to its circuitclosing position in which it is held by a spring-pressed catch I engaging a pin k on a switch extension. -Near the end of the movement of the switch, the pin h becomes disengaged from the pawl : i and the switch completes its movement under its own inertia. The switch g consists of a vessel containing mercury which completes the circuit through contacts j when the vessel is horizontal; or it may consist of a movable blade co-operating with a fixed contact. The rotation of the cam d causes an arm n to move away from the catch l. The arm n is carried by the spindle o of the planet wheel p, Fig. 4, of an.epicyclic gearing p, q, and is returned by the operation of the meter to release the catch l. A coiled spring s attached to the arm n and to the framework assists the meter and exerts its greatest torque when the arm is in engagement with the catch. ' Coin action, mechanical-connection. - A coin inserted into a slotted spindle a carrying the cam. d forms a. connection between the spindle and a peg c rotated by a knob b. The coin drops out after a half revolution of the spindle a, the full revolution being completed by the lever e bearing against the cam d. Coin-slit closing-devices.-A shutter t carried by a notched plate v is moved under the coinslit by the peg c engaging the notch. The plate v is returned by a spring when the peg c leaves the notch, thereby preventing backward movement of the peg c to its initial position. When the maximum number of coins have been inserted the arm n actuates a lever y to raise a stop z behind a projection 2 on the shutter to keep the coin-slit closed until the arm n is moved under the action of the meter.

Filed: 1932-03-16
Abstract: 398,806. Moulding concrete slabs by rollers co-operating with moulds. BATES, H. K., 42, Hawarden Avenue, Sefton Park, Liverpool. March 16, 1932, No. 7738. [Class 87 (ii).] In apparatus for moulding concrete and like slabs in an apparatus in which the mould is traversed underneath multiple pressure rollers to consolidate the material, the rollers are mounted at a fixed distance from the track carrying the mould, and the walls of the latter are adapted to be depressed under the roller pressure as the thickness of the slab is reduced. In the illustrated form a wheeled mould frame H is charged with material and covered with the tensioned band L which is unwound from the spring drum l<1> before being run on the track E beneath the series of pressure rollers B which engage the band and compress the material. The rollers are slightly lower at the exit than at the entering end, so as to effect a gradually increasing compression and after compression they rest upon the slightly depressed upper surfaces of the sides of the mould. After passing beyond the pressure rollers, the mould walls are engaged by fixed cam rollers M<1>, Fig. 4, and lowered further against the action of the springs h<3> to expose the moulded block on the loose pallet h<4> for delivery. Suitable arrangements of chains and ropes are used in conjunction with a winding drum or drums at one end of the track to move the mould backwards and forwards under the rollers. Several machines can be arranged side by side and timed so that one mould is always ready for loading while the others are being compressed and discharged. The track wheels of the mould in the illustrated form may be replaced by a series of small rollers similar to the pressure rollers to reduce the over-all height of the machine.
