Title: Improvements in Stations for Duplex Wireless Telegraphy.
Inventor: BELLESCIZE HENRI JEAN JOSEPH M
IPC: H01Q1/52
Filed: 1919-07-05
Abstract: 136,524. Regnauld de Bellescize, H. J. J. M. de. Dec. 7, 1918, [Convention date]. Aerials and like radiating and receiving conductors; duplex wireless signalling.-In a duplex system of wireless telegraphy, disturbances due to a transmitting-aerial upon a closed receiving- aerial at the same station are annulled either bv arranging the aerial and its supports symmetrically about a plane passing through the transmitting-aerial and at right-angles to the plane of the closed receiving-aerial, or by inclining the receiving-aerial, or by providing one or more auxiliary closed aerials contained in a resonant circuit inductively coupled to the main aerial, or by placing an auxiliary open aerial out of the plane of the main aerial. Compensating receiver circuits of the kind described in Specifications 132,434 and 132,435 may also be employed. The transmitting-aerial A, Fig. 1, and all conductors associated with it are arranged symmetrically about a plane passing through the aerial and arranged at right-angles to the plane of the closed receiving-aerial B at the same station, so that for each part a, a on one side of this plane, there exists a corresponding portion a<1>, a<1> on the opposite side of this plane. When the aerial cannot he modified in this way, the plane of the receiving-aerial B is inclined to the vertical, its position being determined by trial. After the aerial B has been inclined to reduce the disturbance due to the adjacent transmitting- aerial to a minimum, auxiliary aerials D<1>, D<2>, Fig. 2, placed at right-angles to the plane of the aerial B and coincident to it respectively, are placed' in a resonant circuit, and the aerial D<2> is inductively associated with the aerial B to reduce the disturbance further. The aerial D<1>, D<2> may be replaced by a single frame inclined to the plane of the aerial B. The compensating-arrangement shown in Fig. 4 consists of coils a, b inductively associated with the receiver circuit and an adjustable inductance d, the arrangement being such that the actions of the earth currents i<a>, i<0> which arise when the closed aerial is regarded as an open aerial are balanced out. In a modification, Fig. 5, inductances, resistances, and capacities K are inserted to counterbalance the capacity effects C<11> of the coils a, b, S<11> and the capacity effect C<111>. The balanced arrangement shown in Fig. 5 of Specification 132,435 may also be employed. The Specification as open to inspection under Sect. 91 (3) (a) describes an arrangement in which an auxiliary open aerial, the position of which lies out of the plane of the aerial B, Fig. 1, may be provided and placed in such a position that radiation from it counterbalances the disturbances in the aerial B due to its adjacent transmitting-aerial. This subject-matter does not appear in the Specification as accepted.

Abstract: 754,882. Television. VITARAMA CORPORATION. June 10, 1954, No. 17139/54. Class 40 (3). [Also in Group XX] In apparatus for recording a scene, a television camera views the scene and supplies signals to a local picture tube imaged on to a photographic recorder, a common synchronization generator being connected to the camera and picture tubes to cause them to scan in synchronism an means being provided to synchronize the common generator with the film movement. Fig. 1 illustrates the invention as applied to a system in which three camera heads 11-13 are arranged to view adjacent portions 21-23 of a wide scene, each camera head, Fig. 2 (not shown), comprising three pick-up tubes 31- 33 associated with an assembly of dichromatic mirrors so as to generate red, blue and green component signals. The signals appear on leads 41-43 and are applied through amplifiers 49 to picture tubes 46-48, a set of three tubes being provided for each camera head. A film recorder 52 is provided for each reproducer tube, the recorders operating with continuous film movement and all being driven from a motor 60. A common synchronization generator 62 applies scanning signals to both pick-up and picture tubes, horizontal (line direction) scanning alone being used for the picture tubes, the film movements supplying the vertical component of scan. In order to ensure that the camera signals are generated in timed relation with the film movement, a contact system 75 (illustrated in greater detail in Fig. 3, not shown) is actuated by a cam 90 carried on one of the drive-shafts to the recorders and provides a pulse at each film frame. This pulse is applied over conductors 64 and initiates the vertical scan signal in generator 62. Reference is made generally to a system using three camera heads providing black-and-white signals, and also to a system using a single camera head. Duplicate recorders may be employed to eliminate any risk of loss of film.

Title: Assemblies of rotors journalled in stators by magnetic bearings
IPC: F16C32/04
Filed: 1975-04-29
Abstract: 1509087 Magnetic bearings PADANA AG 29 April 1975 [30 April 1974] 17673/75 Heading F2A A rotor 12 is journalled by a magnetic bearing system having an actively controlled electromagnetic radial bearing 15, a passive axial bearing 14 comprising a permanent magnet 17 co-operating with a ferromagnet portion 16 of the rotor, and a passive radial bearing comprising a permanent magnet 27 which may also co-operate with a ferromagnetic portion 26 of the shaft. The arrangement is such that the rotor is maintained in an equilibrium position within the bearing system, and in particular the passive bearings are such that, at least within a predetermined operative range of axial displacement of the rotor from its equilibrium position, the change in the stabilizing axial forces applied to the rotor by the passive axial bearing 14 upon such axial displacement is greater than the corresponding change in destabilizing axial forces applied by the passive radial bearing. The actively controlled electromagnetic bearing 15 produces radial forces which oppose the destabilizing radial forces exerted on the rotor by the passive axial bearing element. The electromagnetic bearing is controlled by an electronic controller 21 whose output varies in response to changes in the position of the rotor as detected by sensors 22. The magnet of the passive radial bearing 27<SP>1</SP> may be resiliently mounted, e.g. on a rubber rod 31 (Fig. 3) or by a stack of leaf springs in order to reduce radial oscillation of the rotor. Additionally the magnet may be contained in a reservoir filled with hydraulic oil 32.

[Class 78 (iii)] [Also in Group I] Apparatus for the. intermittent movement of loads by means of a counterbalancing container which can be filled or emptied of liquid or granular material under the control of valves to effect the movements of the load is controlled by a timing device. As described, the apparatus operates on filters. Filters 22 are periodically removed from and immersed in liquid to be filtered by being suspended from a carriage 21 which is caused to traverse inclined rails 23 by means of a counterweighting tank 20. A valve 28 is automatically opened and closed for admitting water from a tank 25 to the tank 20 periodically so that the latter descends into a container 34. Its descent is cushioned by means of an air pocket 35. After the tank 20 has been in the tank 34 for a predetermined time a valve 31 is automatically opened and the tank rises. The cycle is then repeated. A controller for the valves comprises a cam disc 52 continuously driven by an electric motor and operating the cables 29, 37 which actuate the valves. A further cam on the disc 52 actuates valves which control the suction and air-blowing through the filters such that suction is applied whilst they are in the liquid and for the beginning of the time that they are elevated, whereafter it is cut off and air blown through to remove the filter cake. Whilst air is being blown through the filters an air valve 66 and a. fluid discharge valve in the vacuum receiver 48 are opened to evacuate the receiver. The filters comprise drum-like members suspended from the carriage 21.

Patent GB-180639-A (GB)
Abstract: 180,639. Krupp Akt.-Ges., F. May 23, 1921, [Convention date]. Momentary-contact switches, mechanical. - A time switch for welding &c., adapted to close a gap r<2> and after an interval of time open it, has the movable contact a<1> mounted on a rotatable member A controlled by a spring E and coupled through a spring D to a fly-mass C which can also rotate loosely. On pressing the lever M, the rod J rises and carries with it the member H and rod G until a fixed stop K disconnects the member H and allows the spring F to carry the rod G downwards till it strikes a stop a<3> on the disc A. The disc A is thus set in rotation and carries with it the fly-mass C by engaging a stop c<1> fixed to the latter. The contact a<1> reaches the gap r<2> but the fly-mass C moves on compressing the spring D. It then moves back, reaches and carries with it the disc A and contact at r<2> is broken. The time interval may be varied by providing an adjustable stop (not shown) to limit the movement of the fly-mass C. In welding, actuation of the rod M not only completes a circuit through the primary coil R of a transformer, but also presses the electrode p<1> on to a piece of work lying on the electrode q<1>.
