Title: Monitoring of liquids
IPC: G01N21/53
Filed: 1971-08-19
Abstract: 1347149 Detecting impurities in liquids photo-electrically ENVIRONMENT ONE CORP 19 Aug 1971 [20 Aug 1970] 38906/71 Heading G1A A liquid subject to foaming is monitored for the presence of particle impurities by measuring the attenuation of a beam of light passing through the liquid after gas bubbles have been removed. The monitoring apparatus is contained within a cylinder 6 having end apertures 4 and 5 through which oil can flow when the cylinder is immersed in an engine housing. A rotor 17 contains two test chambers and two reference chambers, each chamber comprising an axially extending through passage 22. As the rotor is rotated, either by a moving oil stream driving the vanes 24 or by a motor drive, the chambers pass sequentially between a light source 27 and a photo-transistor or photo-resistor 34, the source and photo-cell being provided with fibre optic light guides 31, 32. The two diametrically opposed reference chambers (23, Fig.3, not shown) each contain a glass rod. Both test chambers (47, 48) are sealed at each end with a glass window, and oil flows into and out of them through axial openings 25. One of the test chambers has a filter screen (51, Fig. 5, not shown) at its inlet and outlet ends (the direction of oil flow being optional) having a mesh size which passes impurities but filters out bubbles. As the rotor rotates the photo-cell output is a sequence of pulses (Fig.6, not shown) corresponding to the transmissivity of, respectively a reference chamber, oil sample with impurities and bubbles; a reference chamber; oil sample with impurities only. Hence both the impurity content, indicating chemical breakdown, and bubble content may be indicated on recorders. A warning light may be operated by the bubble content output. Impurity and bubble content may also be determined by monitoring scattered light. For this, each chamber is provided with an axial opening 41 aligned with a further photo-cell 44. In the two test chambers this opening is sealed with a lens (50). Once per revolution a reflective surface 36 reflects a portion of the light beam to a further photo-cell 39 to provide a marking pulse. The absence of such a pulse may be used to trigger a light or other indicator to show a system breakdown, e.g. light source or rotor failure.

[Also in Group XXV] A screw is formed by twisting a parallelsided, flat strip 1, e.g. of brass, about its longitudinal axis so that the axis remains straight and the edges 2 form helices, these edges being formed with a screw-thread coaxial with the helices and of a pitch smaller than that of the helices. An untwisted end portion 3 of the strip may provide the means for turning the screw and may have a hole which may contain a pin, Figs. 3, 4 (not shown). For turning by hand or by a flattened tube, it may bear a pressed-on cap 4 with a flange 5 for bearing on the workpiece. It may be bent to one side, Fig. 6 (not shown), or divided and bent to both sides, Fig. 5. A solid cheese-head may be pressed on to it, Fig. 7 (not shown), or it may be larger than the rest of the strip and formed with downward extensions 14, Fig. 10, which are curved each to one side. These extensions 14 may be directed in a clockwise direction on a left-hand screw, for example, so that sharp edges 15 precede the roots of the extensions when unscrewing, so that such action is impeded. The strip may be twisted for its whole length, Fig. 8, a cap being pressed or screwed on its end. The cap may be a plain open cylinder, Fig. 9 (not shown), in which case the screw is turned by the fingers or a tool with a slot for receiving the strip end or the cap may be formed with a screwdriver slot 12 and a flange 5. A number of open caps which may each have a flange may be spaced along a continuous strip and pressed or rolled on before the strip is cut in screw lengths.

Abstract: 830,225. Electroluminescence. SYLVANIA ELECTRIC PRODUCTS Inc. Dec. 21, 1956 [Jan. 31, 1956], No. 39067/56. Class 39(1). [Also in Group XXIII] Method of manufacturing an electro-luminescent lamp includes the steps of applying a paste, comprising, in specified proportions, a mixture of an electro-luminescent phosphor and glaze-forming (including glass) material in an oil-base vehicle, to a lamp base member through a screen, and heating the paste to a temperature sufficient to remove the vehicle. An oil-base vehicle comprising pine oil and a methyl ester of wood rosin is referred to. The oil-base vehicle can comprise about 82% by weight of pine oil and about 18% by weight of methyl ester abietic acid. The heating temperature is below that required to effect fusion of the glaze-forming material, e.g. about 750‹F. After the oil-base vehicle has been removed by the heating the glaze-forming material is fused or sintered. Apparatus for carrying out the method is described in which a squeegee is used to draw the paste across a hinged screen and force it through the screen on to a flat lamp base member. 200 and 150 mesh screens having wire sizes of 0À0021 and 0À0026 inches for forming layers of paste of 0À0015 and 0À002 inches thick, respectively, are referred to. A completed electro-luminescent lamp is shown in Fig. 4, and comprises a metal plate 3, a porcelain coating 5, a conductive coating 7 and a layer 9 of electro-luminescent material embedded in glaze material. A transparent conductive coating is subsequently applied to the layer 9, the two conductive coatings forming the electrodes. The porcelain coating 5 and the conductive coating 7 may be omitted, the metal plate 3 forming one of the electrodes and to which the layer 9 is applied. In a further modification a glass plate with a conductive coating on one side can be used, the layer 9 being applied directly to the other side of the glass plate. A lead-containing copper-activated zinc sulphide phosphor can be prepared as described in U.S.A. Specification 2,728,731 by mixing specified proportions of zinc sulphide (containing 2À5% chloride by weight), zinc oxide, lead carbonate and copper oxide, and firing in covered porcelain crucibles. A suitable glaze-forming material is the powder described in Specification 780,584.

IPC: H01Q7/08
Filed: 1960-11-21
Abstract: 1,007,791. Frequency changing arrangements; aerials; controlled non-linear inductors. PLESSEY CO. Ltd. Feb. 20, 1962 [Nov. 21, 1960], No. 39927/60. Headings H3B, H3F and H4A. A ferrite rod aerial is adapted to act as a frequency changer. It is formed by two parts 1, 2, Figs. 1-4, connected by four identical bridge portions 3-6, whose identical magnetic reluctance is lower than that of the end parts 1, 2. The bridge portions 3-6 carry a number of windings, including serially-connected output windings 7-10, Fig. 2, on individual limbs, the output windings on adjacent limbs being wound in opposite directions. Each bridge portion also carries one of four serially-connected local oscillation windings 11-14, Fig. 4; the assembly also includes a pair of seriallyconnected biasing windings 15, 16, Fig. 3, to which a D.C. biasing current is applied, each of which embraces an adjacent pair of bridge portions. The last windings may alternatively be replaced by a pair of permanent magnets. The amplitude of local oscillations and current applied to the biasing windings are such, and the windings so arranged, that on each halfcycle of local oscillations two of the bridge members are swept to a point at which non- linearity of the magnetic characteristics occurs; in the one member the signal flux assists the other two fluxes and saturation will occur, so that the signal flux will divide unequally between these two members, flowing through the other member, in which it carries the material away from saturation. Sum and difference frequencies thereby appear in the output windings 7-10; these windings are, however, so arranged that the local oscillations do not appear in the output. The difference frequency is used, the output circuit being resonated at this frequency by means of series inductance 22, Fig. 2, and adjustable capacitor 23; the difference frequency is made several times the input frequency, a power gain being thereby obtained from the device. As a protection against the image frequency winding 17, 18 are located on the parts 1, 2 of the aerial rod, being resonated at this frequency by means of capacitor 19 so as to reduce the effectiveness of the aerial at this frequency. In an alternative embodiment the aerial comprises two separated ferrite rods 25, 26, Fig. 6, with four octagonal ferrite plates 27-30 located in the gap between them. The plates carry local oscillator windings 34 wound at an angle of 45 degrees to the axis of the aerial, and output windings 33 wound at right-angles to this axis. Bias is provided by two permanent magnets 31, 32 with their axes parallel to the windings 34.
