Abstract: 1,197,688. Separating oil and water. CHEVRON RESEARCH CO. 27 Sept., 1968 [27 Sept., 1967], No. 46157/68. Heading B1D. [Also in Division C1] A surfactant is added to an oil-water mixture upstream of a coalescer and enables the dispersed phase to coalesce more readily, by forming layers of dispersed phase within the coalescer, after which the phases are separated 'by gravity. The surfactant may 'be anionic, cationic, or non-ionic having the general formula RO-(CH 2 CH 2 O) n -H. When the mixture comprises oil dispersed in waiter, a surfactant with an HLB number of less than 7 is selected, R having 6 to 20 carbon atoms and n being less than 4. When the water is dispersed in oil, a surfactant wherein R has at least 8 carbon atoms, n is at least 7 and having an HLB number of at least 10 is used. 10 to 10,000 ppm by volume of surfactant is added to the mixture. The coalescer may comprise polyester, acrylic or modacrylic fibres, bonded by 20 to 100 parts by weight of polyacrylic or polyurethane resins or synthetic rubber

Abstract: 1383651 Jet propulsion nozzles DEFENCE SECRETARY OF STATE FOR 27 Sept 1972 [5 Oct 1971] 46338/71 Heading F1J The invention relates to a jet propulsion nozzle of a gas turbine by-pass jet engine comprising a series of pivotally mounted flaps for varying the area of the nozzle outlet, there being discharge means arranged to direct a portion of the by-pass air-flow over outer surfaces of the flaps. The nozzle shown in Fig. 1 is the nozzle of a gas turbine by-pass type engine and comprises a duct I having a series of flaps 6 pivotally mounted at the downstream end thereof. The turbine exhaust flow is indicated at B and the by-pass flow at A. A cylindrical member 10 is disposed around the duct 1 to define an annular passage therewith through which a stream of air taken from the bypass flow A flows, being discharged at 12 over the outer surfaces of the pivotal flaps 6, thereby re-energizing the boundary layer so as to maintain flow attachment at the flap outer surfaces. In a second embodiment, the nozzle is of convergentdivergent form and comprises primary flaps 6 and by-pass air-flow means as in Fig. 1 and secondary flaps 16 pivotally mounted on a structure comprising walls 13, 14. Air flows into the nozzle through inlets 15 in the outer wall 3 as indicated by arrow D when the primary nozzle flaps 6 are moved to the reduced area position, the flaps 6 serving to close-off the openings 15 when in their outer positions. Air under pressure is discharged through a duct 17 to flow over the outer surfaces of the flaps 16 when the latter are in the reduced area position shown in chaindot lines.

Abstract: 1,170,526. Automatic focusing. BELL & HOWELL CO. 20 Oct., 1967, No. 47920/67. Heading H4D. [Also in Division G2] The Specification describes automatic focusing and/or distance indicating means, wherein the image of the object to be focused or ranged at image plane 16, Fig. 1, is sampled by a plurality of randomly distributed light paths (e.g. a bundle of optical fibres) and said light paths are randomly distributed into two unequal parts 17 and 17<SP>1</SP> to feed the resulting image samples to respective photo-electric detecting means 20, 20<SP>1</SP>, the difference in the outputs of the detecting means indicating the degree of focusing of the image and rising to a peak, Fig. 4, and the occurrence of focus. A detecting means output comparison means 21, can thus give an output indicating the range of the object or can energize means 28 for refocusing the image. In the embodiment of Fig. 1, n fibres in bundle 15 are divided into nŒ#Vn/2 in limb 17 and n##n/2 in limb 17<SP>1</SP>. Due     to the random mixing of the fibres the ends 12 and 12<SP>1</SP> of the fibres bundles 17 and 17<SP>1</SP> should appear a uniform grey, becoming equal with focusing and the comparison means 21 giving an output representing the light carried by #n fibres. The comparison means 21 is shown in detail in Fig. 3, potentiometer 23 being adjusted to " zero," the indication and resistors 26 being dimensioned to compensate for differences in the frequency. In the embodiment of Fig. 5 the fibres commence in equal numbers in one of two planes 36 or 36<SP>1</SP> equal distances either side of the desired focal plane 37. With this arrangement, focus is indicated by a null output from comparison means 41 the full response characteristic thereof being shown in Fig. 6. The polarity of the output thus indicates for servoing purposes the sense of the defocusing.

Abstract: 1,033,720. Vacuum switches. GENERAL ELECTRIC CO. Nov. 30, 1964 [Dec. 6, 1963 (2)], No. 48537/64. Heading H2B. An axial magnetic field 50 created between the contacts 17, 18 of a vacuum switch by a series-connected coil 52 wound around the outside of the envelope is effective to confine the arc and thus to reduce peak arc voltages when interrupting heavy currents. In a modification (Figs. 4, 5, not shown) a saturable core 60 of grain oriented silicon steel shunts part of the magnetic field so that, in the region of the contacts, it is relatively smaller for low currents (Fig. 6, not shown). To ensure that the field disappears at current zero and that normal interupting ability of the switch is not impaired, phase differences and therefore eddy currents must be reduced to a minimum so that core 60 is constructed as a number of laminated sections; the end plates 12, 13 of the envelope are of stainless steel and spiral slots 32 in the arc surfaces of the contacts are extended into the centre of the contact where holes 70 are drilled.

The member 5 may be fixed to the container by means of a collar 6 clamping flanges 3 and 4 on the container and member 5 respectively together, or by a non-reversible force-fit between a rib on the member 5 or container 1 and a groove in the container 1 or in the member 5 respectively. To empty the pan, its non-spillable property must be destroyed by, for example, breaking off a portion, breaking collar 6, making it of a soluble substance, such as collagen, and dissolving it, pulling or cutting off a portion surrounded by a line of weakness, or cutting off a projecting portion. To prevent easy resealing the outer surface of the container may be grained or irregular and/or include a material, such as silicones, waxes, or camphor, which resists adhesion of, for example, adhesive tape. The bed pan may be transparent or translucent, may be made from plastics material or treated cardboard, and may include 0À01 to 15% by weight of a bactericidal material and 0À01 to 20 per cent of a phosphorescent material. The base of the container may be coated with adhesive material 8 for adhesion to bed clothes or to a stabilizing lead plate. As illustrated the pan is for male use but the member 5 may be modified for female usage.
