Title: A device for sensing an alternating current through a conductor at high potential with respect to ground or an alternating voltage at a high potential with respect to ground or the difference between two large alternating voltages
Inventor: GORDIN BORIS IOSIFOVICH
IPC: H01F38/34
Filed: 1969-04-11
Abstract: 1,271,379. Current and voltage measurement. MAUCHNO-ISSLEDOVATELSKY INSTITUT POSTOYANNOGO TOKA. April 11, 1969, No. 18750/69. Heading G1U. An arrangement for sensing an alternating current through a conductor at a high potential with respect to ground, or an alternating voltage at high potential or the difference between two large alternating voltages, incorporates a number of transformer stages in cascade, the transformer 1 of the initial stage having one end of its primary winding 2 directly connected to an end of its secondary winding 3 which is not grounded, the ends of the secondary winding being connected to the ends of the primary winding of the transformer of the next stage, there being no connection to this next stage primary winding other than to its ends. In a simple arrangement for measuring current Fig. 1 (not shown) the primary (2) of the transformer (1) is connected in the high voltage line, one end of the primary (2) and secondary (3) windings being connected together. The secondary is connected across a further current transformer which delivers an output to a load (8). In a more complex arrangement, a number of transformer stages 1, 11, 12, 6 as arranged in cascade. Equalizing resistors 17 are connected across the transformers in the second and subsequent stages, while matching resistors 18' are connected between the stages. Voltage measurement is achieved by connecting the primary of transformer 1 across a pair of lines. Measurements on polyphase systems are carried out by connecting three first stage transformers in star or delta across the lines, Fig.9 and 10 (not shown). The arrangement provides voltage transformation in the first stage, followed by current transformations in subsequent stages.

Filed: 1969-04-14
Abstract: 1,214,246. Treating canes. L. MILLER. 14 April, 1969, No. 19064/69. Heading D1P. Canes are at least partially filled with a hardenable natural or synthetic liquid, the liquid thereafter being allowed to set. The liquid may be thermoplastic, e.g. polymethyl methacrylate. or nylon, or thermosetting, e.g. polyester or epoxy resin, or it may be one of the naturally occurring gums or resins. Filling of the liquid into the cane tubes may be effected by gravity or under pressure and hardening may be carried out at room temperature or with heating either with or without any catalytic assistance. Straight canes or bent canes may be treated in this way, however, in the latter case pre-treatment of the canes, e.g. with sand, kaolin or mercury and liquid ammonia may be necessary to bend the canes before filling, the pre-filler being removed by air under pressure before treating with the liquid of the invention.

Title: An improved method of and apparatus for separating out and removing matter suspended in a fluid
IPC: B01D25/00
Filed: 1922-07-19
Abstract: 210,101. Shaw, H. S. Hele-. July 19, 1922. Filters; separating by gravity.-A filter comprises a pack of plates or sheets of paper or other material substantially impermeable to the fluid, at any rate, in the direction of flow, compressed between inlet and outlet end plates and so perforated that inlet and outlet tubes are formed within the pack, the liquid filtering between the sheets from the inlet tubes to the outlet tubes. Fig. 1 shows a filter formed of plates 8 compressed between end plates 7, 9. Liquid is passed by a pump 5 from a tank 2 through a pipe 6 to passages 23, formed in the end plate 7, Fig. 2, and communicating with the inlet tubes in the pack. The filtered liquid is collected from the outlet tubes in the pack by passages 25, in the plate 9, Fig. 5, and discharged through a pipe 10 to a tank 11. The plate 9 has also passages 27 communicating with the ends of the inlet tubes in the pack, so that separated matter can be flushed out when a valve 14 is opened. A tank 21 is provided for a washing fluid, which can, if desired be delivered through a bye-pass 19 to the outlet tubes in the pack and thus passed between the plates in the reverse direction. The plates may be of paper or other fibrous material, having a grain or matt surface or projections or raised borders formed by printing or embossing or by depositing and securing thereon any suitable substance. ' Mechanical means, such as screws or levers, or hydraulic pressure may be used to regulate the pressure between the heads and thus control the distance between the sheets. The filtered liquid may be in part allowed to escape at the edges of the plates. Conical plates may be used. Rods may be provided for pushing out from the inlet tubes in the pack solid matter, which is not removed by washing. Steam tubes may be provided in the filter if the liquid to be filtered is viscous. One of the Provisional Specifications describes the use of a pack of sheets for separating solid matter from a liquid as it flows with stream line motion between the sheets. Alternate sheets may be cut like stencils to provide the necessary channels. The solid matter is deposited in pockets from which it can be removed through holes in the plain sheets.

Title: Improved Fibrous Sheet Manufacturing Method and Apparatus.
Inventor: BOSSEN DAVID AUGUST
IPC: D21F1/06
Filed: 1967-05-01
Abstract: 1,192,231. Papermaking. INDUSTRIAL NUCLEONICS CORP. 1 May, 1967 [29 April, 1966], No. 20071/67. Heading D2A. [Also in Division G3] A characteristic of a fibrous sheet formed from a layer of fibrous slurry emerging from a headbox is maintained at a predetermined value by automatically controlling, in dependence on a measurement of the characteristic, the flow of liquid adjacent to one horizontal surface of the slurry layer as it emerges from the headbox. In Fig. 4, a mixture of wood pulp fibrous slurry and white water is supplied to a headbox 18 containing an agitator 40. A slice 90 associated with an opening 20 causes the mixture to emerge as a layer 92 on a paper forming wire conveyor (not shown) from which the paper sheet formed passes to a dryer 24. To ensure a desired moisture content of the sheet 'before it enters the dryer, a moisture detector 100, 102, responsive to any error, controls a hydraulically operated valve 96 so that the flow of white water supplied to form a layer 98 on the upper surface of layer 92 is varied to correct the moisture content. The moisture detector may be scanned across the sheet, signals from it being stored and utilised to control a number of valves such as 96 across the width of the sheet so that a greater moisture content is maintained near the edges to compensate for subsequent greater drying at the edges. To maintain a constant weight of paper, a gauge 104, e.g. of the radiation absorption type, scanned across the sheet leaving the dryer, automatically controls at 108 the flows of white water to a number of sections across the width of the headbox at which the weight may be maintained at different values if a particular cross section of the sheet is desired. If the weight is outside the range of flow control 108, the switch shown may be operated to transfer control to a motor 112, which makes a coarse adjustment by moving slice 90. The flow of white water controlled at 108 may be confined to the lower side of layer 92 by a baffle in the headbox 18 which flexes to vary the relative thickness of the white water layer with variations in the rate of flow of white water. Such an arrangement, without the moisture control but with weight detection, preferably before the dryer, compensated for moisture content variation, is also described. Moisture control as described above with weight control by varying a slice or mixing valve, and weight control as described above with moisture control by varying a water spray or the environment are referred to.
