Title: Electric dust precipitator
IPC: B03C3/74
Filed: 1976-06-08
Abstract: 1519542 Electrostatic precipitators NIPPONKAI HEAVY INDUSTRIES CO Ltd 8 June 1976 23583/76 Heading B2J [Also in Division G3] In an electrostatic dust precipitator including a number of pairs of dust collecting electrode groups 2 disposed parallel to each other in the gas flow direction, and spaced apart transverse to this direction by more than 400 mm, each collecting electrode 3 comprises a hollow, tubular member through which a temperature controlling fluid is passed. The cross-section of the collecting electrodes may be rectangular or circular, with or without additional cooling fins (81), dumb-bell like or somewhat castellated and formed by opposed grooved plates, Figs. 17AF (not shown). The temperature of the cooling fluid flowing through the collecting electrodes 3, headers 7 and 10 and supply pipe 11 having an expansion bend 12 Fig. 4, is controlled by a system, Fig. 16 (not shown), see Div. G3, in which the spark discharges caused by back ionization in the precipitator are detected and the signal derived therefrom is used to control a valve that adjusts the amount of cooling of the circulating fluid. The groups of collecting electrodes are cleaned by respective scraping assemblies 4 comprising two sliding bars 5 which slide along opposed surfaces of the electrodes and are suspended by pulley-driven chains 6 from points intermediate the ends thereof. The chains 6 are connected to brackets 44 on the sliding bars 5 by drawing plates 46, Fig. 9, in an adjustable manner that allows the pressure between the bars 5 and the electrodes 3 to be varied. The faces of the sliding bars 5 have recesses 43 in which are mounted respective sliding blocks (51), Figs. 11A-C (not shown), which may comprise metal or synthetic resin or the like blocks biassed by a leaf spring or rubber backing, or may be formed entirely of elastomeric material. To assist in moving the sliding bars the pulley system may be provided with a counterweight (31), Figs. 7 and 8 (not shown) which slides within a guide tube disposed within one of the collecting electrodes. Adjacent the top end of the electrodes there may also be provided a further cleaning arrangement 9, Figs. 4 and 5, comprising bars 25 suspended on rods 24 from beams 21, which cleans the back surfaces of the sliding bars 5 when they are raised to the top of the collecting electrodes 3. The various relationships between the temperatives of the gas being cleaned and the cooling fluid, the distance between the collecting electrodes, the amount of cooling water used, the velocity of the ionic wind and the apparent resistivity of the dust are discussed with a view to obtaining optimum precipitation efficiency.

Title: Carrier current signalling system
IPC: H04J1/14
Filed: 1949-09-13
Abstract: 676,792. Two-way transmission. DEHN, S. G. (Automatic Electric Laboratories, Inc.). Sept. 13, 1949, No. 23615/49. Class 40 (iv). In a carrier current communication system in which the carrier is used for signalling, a relay 4 for imposing ringing current on a voice frequency line 1, 3 is controlled by the potential across a sharply-tuned resonant circuit. In the embodiment shown, incoming carrier frequency currents from line 41 are applied to the resonant circuit comprising an inductance 85 and condensers 81 and 83 via a high-pass filter 37, lines 43 and 71, transformer 75 and line 35. The potentials across the tuned circuit control a valve 89, the output of which is rectified and fed back to the grid via resistor 113 to reduce the anode current and release the relay 4, which connects a ringing source to the V.F. line and switches in a resistor 67 to maintain the balance of a hybrid transformer 9. Ringing currents from the V.F. line operate a relay 27 which provides a path between a modulator 15 and the line 41 and cuts out a tuned circuit 49 and 57 which normally serves to suppress the carrier. The two-way transmission of speech currents through the single modulator 15 is the same as is described in Specification 672,729.

Title: Improvements in autographic registers
IPC: B41L5/06
Filed: 1921-09-05
Abstract: 168,901. American Sales Book Co., Ltd., (Assignees of Hagemann, L. F.). Sept. 11, 1920, [Convention date]. Feeding and registering webs.-In an autograph register such as described in Specification 136,116, [Class 16, Books &c.], in which the strips are provided with apertures at intervals and the feed roller has a portion of its periphery of a width to enter the apertures so as to cause periodic interruption of the feed, means are provided to prevent accidental operation of the feed roller in either direction when the feed is interrupted. Pins, separate from the feed roller, are also provided to engage the apertures when the strips are initially threaded through the machine to facilitate registration of the strips. As shown, three rolls 4, 5, 6 rest upon the bottom 7 of the casing and on inclined plates 8, and the strips pass together over a plate 13<1> and between narrow feed rollers 14 and a co-operating spring-pressed roller 15. The strips are provided with apertures 17 between each printed form 16 and when these apertures reach the feed rollers 14, the feed is interrupted. This occurs shortly before the engagement of a spring pin 30 in the operating handle 13 with a stop 27 on the casing. Further rotation of the handle brings side plates 40 on the rollers 14 into feeding engagement with the strips, and in this position the pawl 55 engages a notch 56 in a collar on the feed roller shaft to prevent backward movement of the feed rollers. The cover 18 of the casing is pivoted at 19 and is formed as a housing 23 to enclose the roller 15, the front edge 44 of the housing forming a tearing bar for the strips. When the strips are being threaded through the machine, they are registered by means of fixed pins 43 on the casing, which are passed through the apertures 17. The carbon sheets are placed in a receptacle 50 and their free ends are secured by a pivoted bar 51.

Aug. 16, 1939, No. 23685 [Classes 100 (i), 100 (ii) and 100 (iv] A rotary gold or foil blocking- machine comprises a die cylinder 2 carrying one or more segmental curved dies 11, 7 for blocking designs on the front or back of the cover and also on the spine, an impression roller 23 with grippers for seizing the covers and feeding them between the rollers and one or more foils 49 fed from supply rolls 50 by friction between the dies and the blanket of the cylinder 23 and rewound by mechanism which can be adjusted to correspond with the amount of foil paid out which depends on the extent of the design on the die-plate. If two plates are used each can be adjusted on the cylinder 2 and held in the desired position, and the cylinder 2 can be adjusted circumferentially of its driving gear 6. The foils are led over a roll 56 and under bars 57, 58 which guide them into a plane tangential to the rollers 2, 23, a guide 59 being placed under the bar 57 to prevent premature contact of the cover 39 with the foils. The covers are gripped by grippers 29 with adjustable grips 30 carried by an oscillating shaft controlled by a lever 33 and adjustable cams. The cylinder 23 is mounted in eccentric bearings which can be adjusted by a lever 44 and gears to allow for variation in thickness of the covers. The cylinder 23 is fitted with a wide blanket 47, and a narrow one 48 over this in a position corresponding to the spine of the book. The dies are heated electrically by wires 21 supplied with current under control of a switch 22 mounted on a tube 17 which passes through the die cylinder and is formed with flanges 19, 20 to which the wires are fixed. The foil is stripped from the die by a brush 61 which also cleans the die. Each used foil is rewound on a spool 24, Fig. 5, fitted with flanges 116, the spool 94 being carried by a shaft 108 which is mounted between a recessed collar 106 driven frictionally and a brass stud 111 carried by a spring-pressed supporting shaft 112, which can be withdrawn to permit of removal of the wound roller. A pin 109 on the collar 106 engages a slot 110 on shaft 108, and the collar 106 is on a shaft 97 driven from a leather washer 98 on a gear 96 driven from the embossing roller, the washer 98 being in adjustable frictional engagement with a flange 99 on the shaft 97. Prior to reaching the winding spool the foil is advanced by means of frictional rollers 72, 84, the roller 72 being advanced for each rotation of roller 2 by an amount corresponding to the length of foil advanced by the corresponding die plate. Each roller 72 is fitted with a ratchet wheel engaged by a pawl 75 carried by a spring-pressed plunger in a continuously rotating arm 73. This plunger is controlled by a cam the active surface of which is adjustable, so that the pawl is operative for a period which can be adjusted to correspond with the feed of the foil produced by the rollers 2, 23.

IPC: F16J15/00
Filed: 1957-07-26
Abstract: 809,897. Stuffing-box substitutes. SPERRY GYROSCOPE CO. Ltd. July 26, 1957, No. 23765/57. Class 122 (5). A sealing arrangement for an axially movable shaft, for example the piston rod 3 of an hydraulic jack, comprises two axially spaced seals 11 and 12, a leakage space 15 between the seals connected to a sump 18 by a passage 16 controlled by a valve 17 that automatically closes when the pressure in the leakage space exceeds a predetermined value, and a leakdetecting device, for example a pressure gauge 21 or a pressure-operated warning indicator, responsive to the pressure in the leakage space. Normally fluid leakage past the inner seal 11 drains to the sump but if the leakage becomes sufficient to build up the pressure in space 15 to a predetermined value, the valve 17 closes against its spring and the seal failure condition is indicated on the pressure gauge. The outer seal 12 may be periodically tested by turning a cock 22 to close the connection between the sump 18 and the passage 16 and connect the latter to the source 7 of operating fluid pressure for the jack. The ball valve 7 may be replaced by a fine restrictor valve capable of passing normal leakage but insufficient to relieve pressure build up due to inner seal failure.

Abstract: 1,042,345. Record cards. SVENSKA DATAREGISTER A.B. June 14, 1963 [June 21, 1962], No. 23792/63. Heading G4M. A record card is provided with parallel non- reflective stripes 2 defining reflective code areas 4 therebetween, and data are recorded by modifying, e.g. by colouring, the reflective characteristics of selected areas 4. In the example, shown, the top two areas 4 are left unmodified to act as a start code, the next area 4 is used to record a parity bit, and the remaining areas 4 are used in groups of four to record in binary coded decimal code, the least significant bit being uppermost. An unmodified area 4 is classed as " 1 " and a modified area 6 is classed as " 0," this choice enabling feeding of the card in the wrong direction to be detected. The elongated nature of each area 4 also enables correct sensing to take place even when substantial skew of the record occurs, as indicated by arrows A, B. Sensing may be performed by two photo-sensitive devices both of which respond to areas 4, but only one of which responds to areas 6, the latter device providing shift pulses for a shift register while the other device provides data pulses.

Abstract: 510,642. Coating with metals. FIDES GES. FUR DIE VERWALTUNG UND VERWERTUNG VON GEWERBLICHEN SCHUTZRECHTEN. Aug. 12, 1938, Nos. 23870 and 23871. Convention dates, Aug. 12, 1937, and Aug. 21, 1837. [Class 82 (ii)] [Also in Group XL] To obtain a good. coating on insulating material by vaporization in vacuo or cathodic atomization of metals, such as zinc, cadmium, or magnesium, which owing to their low adhering capacity can only be imperfectly directly deposited, the insulating material is first provided by vaporization or atomization with a coating of a metal of the sub-group of the first or fourth group of the period system, e.g., silver, copper, tin, or lead. The preliminary coating may be very thin, e.g., of atomic thickness, its function being to provide crystallization seeds for the metal of the final coating. The continuous coating of strips of paper or synthetic insulating material may be carried out in a vaporization or atomization chamber having two coating points, one for the preliminary and one for the main coating. If it is desired to leave a part of the material uncoated, e.g., the edge of a strip for use in a condenser, the part in question may be covered during the preliminary metallizing step. In coating a strip 1 on both sides for use in a condenser, bars 4 and 5 may be placed as shown during the preliminary metallizing so that the coatings are insulated from one another, each covering most of one side and extending round one edge. The Specification as open to inspection under Sect. 91, describes also other means for providing crystallization seeds on the material prior to metallizing, for example incorporating titanium oxide in paper, either by rolling or by mixing with the paper pulp, or powdering the material with a substance such as titanium oxide. This subject-matter does not appear in the Specification as accepted.

Abstract: 888,435. Variable capacitors. LUCAS (INDUSTRIES) Ltd., JOSEPH, and POLASEK, K. July 28, 1958 [July 29, 1957], No. 23901/57. Class 37. In a variable capacitor comprising a pair of coiled electrode strips a, b, and a saturable laminated iron core d extending through the coil; an exciting winding e, lying in slots in the core, is fed with a current, the variation of which varies the electromagnetic field of the winding e, and hence varies the inherent inductance of the coiled electrodes, whereby the capacitance of the capacitor is varied. The terminals al, b1 are respectively connected to the outer end of electrode a and the inner end of electrode b, so that the inductance of the strips is added to the capacitance. Variation of the inherent inductance of the strips thus varies the rate of charge of the capacitor and hence varies the effective capacitance of the capacitor. In another embodiment, Fig. 3 (not shown), a circuit is shown wherein the winding e is fed with alternating current.
