Title: Detection and recording of oil in mixtures of oil and water
IPC: G01N33/18
Filed: 1972-08-15
Abstract: 1429470 Photo-electric analysis of oil pollution CLARKE CHAPMAN Ltd 31 May 1973 [7 June 1972 15 Aug 1972] 26651/72 and 38094/72 Heading G1A The amount of a contaminant in a fluid sample is determined by bringing the sample into contact with a tape and then detecting the amount of contaminant on the tape. Various detection methods are suggested, including photo-electrically measuring fluorescence which is excited by ultraviolet or infrared radiation. Other methods use detection of a nuclear, electrical or chemical property, or measurement of the heat of combustion. The tape is stored after the test so that it can be subsequently reanalyzed if required. When applied to measuring the amount of oil pollution in a sea sample the tape is preferably of paper coated with silane and silicon dioxide, though tapes of stainless steel, white P.T.F.E. or Myler (RTM) may be used. This traps oil in preference to water when the sample is sprayed on to the moving tape, Figs. 1-3 (not shown). The measuring may be effected by a vessel at sea, the tape being stored for subsequent checking on shore; a further tape may be interleaved with the measuring tape to absorb the contaminant therefrom. The speed at which the tape runs may be varied in accordance with the measured amount of contaminant, the speed increasing when more contaminant is present. A method of reeling a large quantity of tape on one shaft is proposed for long voyages, as shown in Fig. 4. The tape is preferably marked to indicate the time of the measurement, or the position of the ship.

Abstract: 1,158,148. Rotary-piston machines. PERKINS ENGINES Ltd. Aug. 31, 1966 [Sept. 10, 1965], No.38837/65. Heading F1F. A rotary-piston machine comprising a rotary piston mounted for eccentrically generated planetary rotating movement within a housing having a peripheral wall and spaced end walls which with the piston define variable volume working chambers includes a stationary shaft on which is rotatably mounted an eccentric which in turn rotatably mounts the piston. The machine is described as an I. C. engine of the kind having a three-sided piston 18, Figs. 1, 2, planetarily rotatable in a housing 10 having a two-lobed epitrochoidal peripheral wall 19, spaced inner end walls 14, 12 through which the shaft 16 passes and outer end walls 15, 11 fixedly supporting the shaft. The shaft 16 is formed with a set of gear teeth 21 accommodated in an annular recess 22 in the mid axial portion of the eccentric 17 which engage a ring of teeth 25 formed on or secured to the inner peripheral surface of the piston 18. The eccentric 17 is journalled in bearings 23 for rotation on the shaft 16 and formed integral with or secured to flywheels 29 fitted with balancing weights to balance the eccentric whilst the piston 18 is journalled in bearings 26 for rotation on the eccentric. The arrangement permits a shaft of adequate size, symmetrical arrangement of the bearings, wider teeth on the gearing with consequent reduction in load thereon, and improved lubrication of the bearings and gears and cooling of the piston. To lubricate and cool the engine, oil from a sump 48 beneath the housing is raised by a pump 60 and passed through a cooler 61 and filter 62 to an axial passage 64 in the shaft. The passage 64 branches radially at two levels 65, 66 to supply the bearings 23. Oil seeps along the bearings to lubricate thrust bearings 50 and the gears and also passes through ducts 67 to lubricate the bearings 26. The oil can then pass through radial passages 71, 72 into piston cooling chambers 45. The oil leaves these chambers through passages 75 which on rotation of the piston uncover radial ducts 76 in the shaft which are connected by axial ducts 77 with the sump. The lower flywheel 29 incorporates a bevel gear 30 which meshes with a bevel gear 33 secured to the engine output shaft 32 which also drives the engine accessories. The machine is also described having twin pistons in twin cavities one above the other with an intervening wall between the pistons. The eccentrics may be arranged in phase or 180 degrees out-of-phase with appropriate balancing. Several arrangements of power plants are shown which include several engine units with the units mounted on a common wall.

Abstract: 344,565. Refrigerating. SIEMENS SCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. Dec. 19, 1929, No. 38954. Convention date, Dec. 22, 1928. [Class 29.] Compression and absorption systems. -In a combined compression and absorption system an absorber 4 is located between the suction side of the evaporator 2 and a compressor 11, so that during the working periods of the compressor, which may be controlled automatically in accordance with the pressure and temperature in the evaporator, vapour is withdrawn from the solution by the compressor, and delivered to a condenser coil 13 and thence through an expansion valve 15 to the evaporator. Vapour returns through a pipe 3 to the liquid space of the absorber. Heat is conveyed to the solution from the surroundings by gills 6, and also from the compressor and motor when these are located in the liquid, so that no absorption takes places while the compressor is working, the gas merely accumulating above the liquid space of the absorber. When the compressor stops, however, absorption begins and evaporation continues at higher pressure and temperature, until another operating period of the compressor ensues. A separator 8 is located in the compressor suction. The condenser is coiled around the gills 6, or, according to a modification, is located in the liquid. The pump and motor casings may be sealed together to avoid the use of a stuffing box. The plant is particularly suited to domestic refrigerators.

Title: Methods of measuring sizes of particles
IPC: G01N15/02
Filed: 1971-08-21
Abstract: 1417691 Photo-electric investigation of size distribution of particles CAMBRIDGE CONSULTANTS Ltd and WELWYN HALL RESEARCH ASSOCIATION 21 Nov 1972 [21 Aug 1971] 39298/71 Heading G1A Size and size distribution of particles moving through a liquid are investigated by utilizing the Doppler change in frequency when electromagnetic radiation is scattered by the particle(s). In the arrangement of Fig. 1, a helium-neon laser and beam-splitter, 3, provide two coherent beams 5, 7 to be focused on a volume 11 within a jar. The particles in the contained liquid are investigated when settling under gravity such that Stoke's law is applicable. The light scattered from volume 11 is detected at 13 and analyzed by processing circuit 17 which may be as in Figs. 1 A or 1B (not shown). In the former, used when one particle is being scanned at a time, the output is applied to a bank of ten narrow pass filters 21 coupled to respective counters. The detector 13 produces an output at a frequency f equivalent to the Doppler change in frequency of the laser beam, this being dependent on the particle velocity V, which itself is proportional (under Stoke's law) to D<SP>2</SP>, the diameter of the particle. The counters in circuit 17 as in Fig. 1A (not shown), therefore provide the numbers of particles in a plurality of size ranges. In the second case, Fig.1B (not shown), circuit 17 comprises a time compression spectrum analyzer coupled to a normalizing circuit; this provides a continuous size distribution spectrum to be displayed on a cathode ray tube, pen recorder &c. In the arrangement of Fig. 2 (not shown), a single beam from a laser is focused by a lens on to a small volume within the sample. The emergent light is allowed to pass through two apertures in a mask, and the resultant narrow beams focused on the detector. In a further arrangement, Fig. 3 (not shown), light from the laser is divided into two beams by a beam-splitter, one beam being applied to the sample and the other reflected from a mirror to a further beam-splitter where it is combined with scattered (and Doppler shifted) light from the sample.

A device to be used as one junction of a thermocouple in measuring the temperature of a furnace wall has two spaced conductor elements of different materials extending side by side the depth of the furnace wall and being connected at spaced positions along their length by portions of temperature-sensitive semi-conductor material which are electrically insulated from one another by insulating material, so that as the furnace wall and the device are gradually burnt away during operation of the furnace there is at least one portion of semi-conductor material which is heated to approximately the temperature of the inner face of the furnace wall to provide an electrical connection between the two elements. The conductors may be respectively of platinum and of a platinum alloy such as an alloy of platinum and rhodium. The insulating material may be beryllia, mullite, or silica but is preferably present in the form of double bore insulators of sintered magnesia or alumina. These insulators separate portions of the temperature-sensitive material which may be packed in powder form around the conductors within a protective sheath and then sintered. This assembly is embedded in the furnace wall. The temperature-sensitive material may be titanium; zirconia stabilized with lime, magnesia or yttria; mixed titania and stabilized zirconia; or mixed titania and alumina. The inner ends of the conductors may initially be directly connected or may be joined with a wire of the more readily fusible palladium so that the thermocouple may initially operate in the lower temperatures prevailing during start-up of the furnace. The outer ends of the conductors are taken via known compensating leads to known associated equipment.
