Title: Corona-discharge electrodes for electrostatic precipitators
Inventor: HUEPPI HANS
IPC: B03C3/41
Filed: 1965-12-22
Abstract: 1,100,328. Electrostatic precipitators. ELEX A.G. 22 Dec., 1965, No. 54420/65. Heading B2J. A corona-discharge electrode for an electrostatic plate precipitator comprises a tubular support 1, Fig. 1, on which are arranged arms 3, each arm being divided at its end into two corona-discharge tips 4 which are oppositely bent back from, and are oblique to, the plane of the arm.

Title: Magnetic bearing apparatus
IPC: F16C39/00
Filed: 1974-12-19
Abstract: 1485290 Automatic control of magnetic bearings SPERRY RAND CORP 19 Dec 1974 [14 Jan 1974 (2)] 54833/74 Heading G3R [Also in Division F2] A magnetic bearing, rotational for a gyroscope or providing vehicle suspension, for a member movable relative to another in two orthogonal directions comprises magnetically permeable cores on each member having polepieces which together define four gaps, one of the cores having a permanent magnet whose flux resists movement in one direction, resulting instability in the other direction being overcome by the provision of at least two electromagnetic coils on the said core, energized in response to movement in said other direction, and means are provided for modifying the electromagnetic flux in a way which augments the resistance to movement in the said one direction. Fig.2 shows part of a magnetic bearing for a gyroscope shaft 12. The shaft carries a generally W-shaped, in cross-section, core 35 while a stationary support has cores 50, 51 with a permanent magnet 31 and coils 32, 33 together defining gaps G1 ... G4. The permanent magnets resist radial movement since the pole faces tend to align in the position of minimum reluctance, and the inherent axial instability of this arrangement is prevented by energizing the coils to produced fluxes of one polarity in G1, G2 and the opposite in G3, G4 in response to an axial position sensor not shown in Fig. 2. The energization of one coil is varied by the amplified displacement error signal and the other by its time derivative, circuit Fig. 4 (not shown). The construction of an actual bearing is described, Fig. 3 (not shown); it includes copper damping rings in the pole faces and roller bearings for "back-up" support for violent movements. During run-up or slow down the electromagnetic flux is modified  by an additional, constant, current, in the same direction in each coil; it is shown that this increases radial stiffness, and so may avoid transient resonances. The reversal may be effected by a tachometer signal, for a prescribed time, or by a resonance, radial, detector. A six-gap construction is envisaged, Fig. 6 (not shown). To support a vehicle, Fig. 7 (not shown), the W cores are placed on edge to form rails while the other cores carrying the coils and the permanent magnet are carried by the vehicle, which also has the energizing and control apparatus. The detectors sense the gap between the cores.

Abstract: 1410608 Magnetic storage arrangements PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 30 Nov 1972 [3 Dec 1971] 55341/72 Heading H3B Read out noise in a magnetic storage matrix is suppressed by simultaneously energizing two row wires, e.g. X1, X2, Fig. 2, and a single column wire, e.g. Y7, which are coupled with the cores C11-C168 in such manner that the coincident currents are additive for reading purposes in one core, e.g. C17, and substractive in the other, e.g. C27, the two energized rows of cores being respectively associated with two different sense wires S1, S2 which provide electrical paths of substantially equal length from any two selected cores to a differential sense amplifier SA. The row and column wires are energized by generators F1-F16, G1-G16 and E1-E8, L1-L8, respectively, and each sense wire is grounded at its ends through matching impedances R1-R4 and has its centre point connected to the differential amplifier. The sense wires are also used for inhibit signals from generators K1-K4 which by-pass the sense amplifier to ground through diodes H, I. Modifications involving the winding sense of cores in adjacent rows and the particular pairs of row wires to be simultaneously energized for reading are described with reference to Figs. 3 to 6 (not shown). In Fig. 6 such pairs of row wires are X1, and X16' X2 and X15, X3 and X14, and so on, and the length of sense wires necessary in this case is reduced by the folded construction shown in Fig. 7 in which the two wires of each pair are immediately adjacent.

Abstract: 1400225 Determining distance photoelectrically VILLAMOS BERENDEZES ES KESZULEK MUVEK 1 Dec 1972 [3 Dec 1971] 55697/72 Heading G1A Apparatus for indicating competition results expressible as a length e.g. long-jump distances has a radiation emitter along one side of all or part of the competition area, signal detector means comprising N individual sensors on the opposite side each receiving radiation from the emitter and means for indicating or recording either all the sensors that are shielded from radiation or only that corresponding to the least distance. The apparatus may comprise a no-jump determining device which prevents an output. As shown, the apparatus can work in either mode and utilizes phototransistors 25 as radiation detectors . All bi-stables 30 and 31 are initially set to state 0 by switch 37. To record all interrupted sensors, switch 36 is in the upper position (logic 0) and the input passes via AND gate 27 (enabled via inverter 26) and sets bi-stable 30. The output of this passes enabled AND gate 32 and OR gate 34 and activates the associated indicator or recorder 35. To indicate only the detector corresponding to the shortest distance, switch 36 is in the lower positiun (logic 1). The signal passes via AND gate 28 and OR gate 29 to set bi-stable 31 to the 1 position. The output of this passes AND gate 33 (enabled by the 0 setting of the previous stage bi-stable and activates the indicator 35 via OR gate 34. The lowest switched bi-stable 31 switches all bi-stables 31 of higher stages via OR gates 29 and thus prevents the enabling of AND gates 33 of these stages so that the corresponding lamps 35 cannot be illuminated.
