Title: Radiation fluid analyser
Inventor: MUNDAY CHARLES WALTER
IPC: G01N21/35
Filed: 1959-10-09
Abstract: 899,973. Photo-electric fluid analysers. DISTILLERS CO. Ltd. Sept. 7, 1960 [Oct. 9, 1959], No. 34223/59. Class 40(3). A radiation fluid analyser comprises a source of radiation producing a beam which is split into two beams sequentially chopped and passed in sequence to a detector system comprising means s for discriminating between t h e signals induced at the detector by each beam, and means for amplifying and converting each of the signals to a D.C. signals and means for measuring the ratio of one of said D.C. signals with respect to the other. As shown for an arrangement to detect the measurement of water in acetone, light from a tungsten lamp 1 is passed through a collimator 2 and filter 3 passing infra-red radiation of wavelength 1.45Á for which water has a characteristic overtone absorption, but acetone has only a small background absorption. The collimated parallel beams are passed through a double aperture plate 4 to a chopper cylinder 5 having apertures 6, 7 disposed at right angles and driven via gearing 10, 11 from a synchronous motor 8. The beams pass to a cell 13 containing pure acetone and to a cell 14 containing the sample under test and are focused by a lens 15 on to a scrambler device comprising a ground glass screen 16 placed in front of a cylindrical brass tube 17 of highly polished internal surface, behind which is located a lead sulphide cell 18. The signals from the cell 18 are passed via an amplifier 19 and a synchronous switch 20 to an integrating and ratio-detecting circuit 23 controlling an indicator 24, which may be calibrated to show the percentage of water in the acetone. The switch 20 is controlled by an A.C. generator 21 driven from the synchronous motor 8, and in order to provide chopped radiation pulses at the frequency of the motor 8, the gear wheels 10, 11 are in the ratio of 1:2. In a modification, using a reference wavelength, the acetone / water mixture is circulated through the cells 13, 14 in series and the filter 3 is removed from its position shown in the Figure and placed at any point between plate 4 and lens 15 in the path of the beam passing through cell 14. Another filter placed at any point between the plate 4 and lens 15 in the path of the beam passing through cell 13 must be such as to pass radiation in the overtone region but to exclude the overtone wavelength at which water absorbs strongly and any overtone wavelength at which acetone absorbs strongly, so that this beam becomes the reference wavelength beam. Visible or ultra-violet radiation or infra-red radiation in the fundamental wavelength region may be employed. Specification 781,972 is referred to.

Title: Improvements relating to the coin mechanism of prepayment meters
IPC: G07F15/02
Filed: 1946-12-20
Abstract: 627,725. Prepayment mechanism for meters. BEGWACO METERS, Ltd., and BUTTERWORTH, E. Nov. 20, 1946, No. 34443. [Class 27] Limiting amount prepayable. A lever, brought into the path of the rotary coin holder when the maximum prepayment has been reached to prevent return of the coin holder to its coin receiving position, is adapted, by yielding, to allow the coin holder still to be moved in the forward direction to discharge a coin therein. The lever u pivots at t (Fig. 4) on a bracket s secured to a spindle r, a spring x holding the lever up to a fixed stop z. Spindle r also carries a geneva quadrant n (Fig. 3), which is engaged by a driver k on the valve actuating cam f when, as shown, the prepayment limit is being approached. Further prepayment (anti-clockwise rotation of cam f) then causes clockwise rotation of spindle r and this brings the tip w of lever u up into the path of the coin holder a which cannot then be turned back to the coin receiving position. Anti-clockwise movement of the coin holder to discharge the coin is, however, permitted by the lever then turning on its pivot t and against the spring x. The valve cam f is that described in Specification 619,026.

IPC: F27B14/14
Filed: 1921-12-22
Abstract: 194,819. Teisen, T. Dec. 22, 1921. Gaseous-fuel furnaces.-In a crucible furnace for melting glass, metals &c. of the kind in which the heating-means, including recuperator f or regenerators, are arranged below the crucible chamber e, and in which the heating-gases are delivered to the crucible chamber through a vertical port c in the floor, leaking of spilt glass &c. into the recuperators is prevented by a system of cooling-passages comprising horizontal channels i and vertical chambers g, the latter of which serve as connections between the recuperators and the delivery ports p. Beneath the port c is the waste pocket q, and in the construction shown, in which the producers a are built into the furnace base, a port r leading direct to a recuperator is provided so that any accumulation of metal in the pocket will be kept in a molten state. When gas is supplied from an outside source, an air port is fitted in the gas supply channel so that combustion is initiated in the waste pocket q. The chambers g communicate with the port p through a circular flue o, or a pair of quadrantal flues, and from the ports, cleaning passages lead to the outside of the furnace.

Title: Improvements in or relating to turbines
IPC: F02C1/00
Filed: 1921-12-22
Abstract: 174,055. Suczek, R. Jan. 10, 1921, [Convention date]. Working-fluid supply.-Liquid jets for actuating a turbine are produced by the periodic explosion of gases acting on a liquid which is also subjected to centrifugal force. A ring of turbine buckets r', coacts with liquid jets from nozzles s<2> carried by a rotating member D which houses the combustion chambers 1 - - 8 and the baffles b<1>, c<1>. The member D rotates in the same direction as the members F, F', but at a different speed owing to the differential gearing d<1>, e<1>, f<1>, g<1>, the pinions e<1>, f<1> being carried on a member h<1> loose on the shaft S to which the members F, F<1> are keyed. A motor k' may rotate the member h<1> so as to vary the differential speed. A pump P delivers water through a heat regulator p<5> to an inlet m<1>, whence it flows under centrifugal force through ports o<1>, p<1>, q<1> in the members F, D, a port q' communicating with each combustion chamber. Air is drawn into these chambers from a chamber I having ports w<1> registering periodically with ports x', and fuel is fed from a chamber y<1> through an axial bore z<1> and ports a<2> registering periodically with ports x', and the gas mixture is compressed by the incoming water and ignited by electrodes e<2>. The water is forced through ports o<2> to the nozzles s<2> by way of ports p<2> in the ring q<2> carried by the member F', and the gases exhaust through ports q<1> into passages f<2>, g<2>, h<2>, j<2> and a pump k<2>. In a modification, the registration between the ports in the member D and the ports in the members F, F<1> is axial instead of radial, and an electric motor is used for starting the members D, F, F<1>. The rotor R may be dispensed with, the nozzles s<2> working on the Barker's mill principle. In another modification, wherein the rotor R is keyed to the shaft S, and the member F<1> is dispensed with, passages are pro. vided to interconnect for a short period the chamber in which ignition has just taken place and the chamber in which mixture is next to be ignited. The turbine may drive a vehicle and also a dynamo-electric generator for lighting, battery-charging and ignition, and current from the batter or generator may be used to operate the electric motor k<1> for regulating the speed of the turbine by varying the differential speed of the turbine elements and controlling the rate of fuel feed.

[Also in Division B1] A valve body 11, Fig. 1, has an outlet 12 connected directly to both an oil supply pipe 3 via a restricted passage 13, and a water supply pipe 2 through a Venturi passage 14 and a valve 16 actuated by one arm 22 of a floatoperated lever. The arm 22 (Fig. 3, not shown) embodies a detent ball 26 which cooperates with spring-loaded balls 27, 28 in brackets 23, 24; the float and valve are held stationary by the detent until the liquid level has fallen to a given extent whereupon the weight of the float overcomes the spring- loading of the balls 27, 28 and the float falls rapidly to effect instantaneous opening of the valve 16. The velocity of the water released by the valve draws oil from the pipe 3 whereby a mixture is delivered to the outlet 12. The action is reversed with a rising liquid level. The valve may be employed for purposes other than mixing.
