Abstract: 1,219,454. Rotary fluid-flow meters. ENDRESS & HAUSER G.m.b.H. & CO. April 9, 1968 [June 12, 1967], No. 17096/68. Heading F1F. In a meter having a varied rotor 8 supported by bearings 17, 18 upon vaned fluid-guiding devices 4, 5, a proportion of the working fluid leaving the rotor enters an annular chamber 24 between a ring 11 on the rotor and rings 14, 15 on said devices. Forces due to eddies 30 balance axial thrust caused by the fluid passing through the rotor. To minimize the effect upon the rotor due to viscosity changes the fluid flowing between the ring 11 and a housing 21 is rendered turbulent by cavities 27. The meter may be such that the fluid-flow can be reversed. A magnet 19 on the rotor energizes a pick-up coil 20.

Filed: 1964-04-24
Abstract: An insulating glass or vitreous enamel comprises in per cent by weight SiO2, 20-34; Bi2O3, 5-13; PbO, 31-58; it contains no B2O3, lead compounds initially present may be e.g. PbO, Pb3O4, white lead, or lead mono-, di-, or tri-silicate.  Also present may be 0-14% in total of one or more of BaO, CaO, MgO, ZnO, and SrO; 0-9% in total of one or more of ClO2, ZrO2, TiO2, and MoO3; and 0-10% in total of Al2O3 and/or La2O3, the balance, if any, consisting of other compatible constituents. The mixture may be smelted at 1150 DEG  C. in an oxidizing atmosphere, e.g. provided by use of Pb3O4 in the starting material; the smelt is then quenched in water, and wetground, e.g. to pass 400-mesh (American Standard); the material may be used as a slip for spraying e.g. on to stainless steel. Alternatively, the ground material may be dried, sintered, and pressed, e.g. into beads suitable for a hermetic seal, e.g. a compression seal or feed-through bead.  The composition may be yellow and may also be opaque.  The material has low thermoneutron capture and consequently does not deteriorate excessively in a nuclear reactor.

Title: Radio direction finder
IPC: G01S1/02
Filed: 1946-06-06
Abstract: 633,067. Radio direction-Finding; automatic tuning correction. STANDARD TELEPHONES & CABLES, Ltd. June 6, 1946, No. 17257. Convention date, June 20, 1945. Addition to 629,948. [Classes 40 (v) and 40 (vii)] In a radio direction-finding system as described in the parent Specification, wherein the signals re-radiated from the dipoles 2, 3 are alternately used to modify the phase of the signals received by antenna 1, a dipole 22 is symmetrically situated with respect to the dipoles 2, 3 and radiates a locally generated signal which is received by the direction-finding system and used for aligning the tuning of the dipoles 2, 3. The aerial 1 which is connected directly to the receiving system is supported on a mast or standard and free aerials 2, 3 are supported by the insulating cross-piece 4, Fig. 4. Housings 14 and 15 contain tuning units which are adjusted through the insulating shaft 17 driven by motor 18 which is controlled by signals supplied over cable 24. The unit within housing 15 also comprises a trimming condenser which is adjusted through insulating shaft 20 driven by motor 19 which is controlled over cable 25. The dipole 22 is supported upon the insulating arm 21 and is fed with locally generated signals over cable 23. In one embodiment of the invention, Fig. 1 (not shown), the signal applied to the aerial 22 is chopped at a suitable rate so that the signal from a distant station whose direction is being determined may be observed between successive transmission from aerial 22. The aerials 2, 3 are tuned to the frequency of reception by means of the motor 18 and the trimmer 13 is then adjusted by the motor 19 until the receiver gives a null indication on the signal radiated from 22. In the embodiment of Fig. 2, the generator 26 supplying chopped signals to the aerial 22 and the receiver 27 are connected to a common control, 28a which maintains the frequency of the generator output and the frequency of reception the same. The output of the I.F. amplifier 28 is separated into two channels, the locally generated signal being used to control a " tracking " indicator 32 while the signal received from the distance station is passed to the cathode-ray tube 30. In the embodiment of Fig. 3, automatic correction is provided. The generator 26 supplies two signals to the aerial 22, one having a frequency just greater than, and the other having a frequency just less than, the frequency to which the conjointly-controlled receiver 27 is tuned. These two signals are separated from the signal from the distant station and from each other in filters 34 and 35 and then applied to motor control circuit which delivers such a signal to the motor 19 that the trimmer 13 is driven into the correct position for alignment of the two dipoles 2 and 3. The Specification as open to inspection under Sect. 91 also describes a system employing two auxiliary aerials symmetrically placed to either side of the array 1, 2, 3 and supplied alternately from the generator 26. This subject-matter does not appear in the Specification as accepted.

[Also in Group XL (b)] In a system for signalling over a power network by pulses of audio frequency current the A.C. generator HFG is connected to the network 12, 13, 14 through a saturable reactor SR, the D.C. winding A of which is supplied from rectifiers MRA, MRB and controlled by a switch RC which may be of the motor-driven cam-operated type or controlled by a mechanical oscillating element. The impedance of the reactor is reflected into the generator output by a transformer TB but alternatively the A.C. windings B, C may be inserted directly in the generator output. A non-linear resistance NLR shunted across the D.C. winding A acts as a surge arrestor and the impedance presented by the reactor can be adjusted by variable resistors YA, YB. Three-phase systems fed by three-phase audio frequency generators and having either saturable reactors in series in each leg or shunted across the generator output are described with reference to Figs. 2 and 3 (not shown), and tuned circuits for filtering purposes are included.

Abstract: 292,979. Ganz-fele Villamossagi Reszvenytarsasag. June 28, 1927, [Convention date]. Addition to 289,834. Regulation, automatic; systems depending on static transformers. - In a regulating device according to the parent Specification, the choke coil 4, Fig. 1, associated with the primary of the transformer &c. 3 is fitted with an additional winding 20 in a separate circuit to vary the control characteristics. The saturation of the core may be varied by direct current in the winding 20, which is either placed on a third limb and surrounding by a short-circuited winding 21 to exclude alternating flux from that limb, or else is placed on a bifurcated limb, the two halves of which are linked by an 8-shaped winding to ensure equality of alternating flux in each. Further, in a three-phase system, the choke coil 30, Fig. 3, for each phase has linked with it a coil 31 in another phase so as to equalize the effects of loads occasioning substantial phase displacement. The coils 31 may be in the secondary circuit of the transformer 3. The Specification, as open to inspection under Sect. 91 (3) (a) comprises also separately-excited auxiliary windings on the chokes in the multiphase arrangements described with reference to Fig. 3. This subject-matter does not appear in the Specification as accepted.

[Class 78 (i)] An escalator is stopped when a safety device mounted on or near the combplate is caused to move from its normal operative position by an obstruction on, or misalignment of, a step. Fingers 50, 51 pivoted at 52 to each side of the combplate 45 extend several inches in front of the comb teeth 46 on one side of the pivot, and on the other side are'disposed beneath shoulders 54 on the combplate.
