Patent GB-865664-A (GB)
Title: Improvements in or relating to cathode ray tubes
Inventor: SCHAGEN PIETER
IPC: H01J31/20
Filed: 1956-09-13
Abstract: 865,664. Cathode-ray tubes. MULLARD Ltd. July 2, 1957 [Sept. 13, 1956], No. 28014/56. Class 39(1). A cathode-ray device comprises a target having a concave operative surface of cylindrical form and means for setting up a trajectory control field in a space extending to the target surface to cause the path of an electron beam, directed into the space from one end thereof with a velocity component parallel to the target surface, to be bent towards the target in the direction of a selected generatrix, which control field is rotatable about an axis parallel to the target for the purpose of varying the desired generatrix position In a television display system, the rotation of the trajectory plane is preferably used as the frame scan while using variation of the trajectory range for the line scan either by varying the field independently of the rotation thereof, or by varying the angle of entry of the beam by a deflection field rotated synchronously with the control field. The control field may be an electric field set up between a target electrode O, Fig. 1, and three conductive repeller electrodes 1, 2, 3. A rotating field of approximately constant intensity may be obtained by applying a constant potential V o  to electrode O, varying negative potentials V 1 , V 3 , Fig. 12, to electrodes 1, 3 and a constant negative potential V 2  equal to the peak value attained by potential V 1  at one end of the frame scan and attained by potential V 3  at the other end of the scan, to electrode 2. The line scan may be obtained by applying potentials as shown to the deflection plates Dh, Dv or by varying the control field as shown in Fig. 10. Instead of three repeller electrodes, two or five, Fig. 7, may be used. In the latter case the field intensity is arranged to increase away from the target to effect an additional degree of focusing of the beam. The repeller electrodes are preferably in the form of metallic coatings on a cylindrical glass envelope, the target being a phosphor coating P on the envelope covered by an electron-permeable conductive coating O. Alternatively, resistive repeller electrodes may be used each having its ends provided with conductive strips across which a potential difference may be applied. In this arrangement the control field may be such as to provide a degree of beam focusing in the direction of scan. The rotatable control field may also be provided by an electro-magnetic arrangement employing two generally rectangular elongated control windings L 1 -L 2 , Fig. 14, the line scan being effected by deflection plates Dh, Dv, located adjacent the electron gun. Specifications 822,911 and 865,663 are referred to.

[Also in Division F1] To maintain a constant pouring rate from a tilting pouring vessel such as a ladle or furnace 1, a cam 21 (secured to a shaft 9 which rotates with the vessel as the latter tilts about the axis 7 of the shaft) controls a valve 23 in an hydraulic oil supply line 47, 48 to a cylinder 11 whose piston-rod 13 tilts the vessel. Apparatus 37 (which can be manually and automatically operated) controls the hydraulic circuit and, by manual operation of a three-way valve which can connect the cylinder 11 with a supply 43 or discharge 45, the furnace 1 is first tilted to an about-to-pour position before the automatic control is switched on. A time relay of the apparatus 37 opens a valve 39 in the line to the valve 23 for a set time so that the cylinder 1<SP>1</SP> starts, maintains and stops the tilting, regulated by the cam 21. To ensure cessation of flow, the relay opens a valve 41 in a line 49 to pass the oil to the discharge 45 instead of to the cylinder. A valve 51 controlled by a time relay can by-pass the valve 23 to increase the pouring rate for an initial period.

A device for testing the correctness of the point in the swing at which a person hits a ball comprises a handle having an extension on which a weight movable towards and away from the handle is mounted, a movable stop to obstruct movement of the weight away from the handle, and a control means for the stop operative to move it so as to release the weight when the handle and extension attain a particular angular velocity. The device may be mounted in or on an actual club or bat, so that a golf swing may be practised in a confined space, a tubular extension 11 of a handle 10 is tapped at its free end to enter into a closing cup 12 forming a guide for a slidable rod-member 13 which is urged towards the handle by a spring 15. Two arms 17 are pivoted to the rod 13 and are urged apart by a spring 18 to project through slots 19 in the member 11 and form a stop preventing an annular weight 20 from sliding away from the handle. During the swing of the club, centrifugal force urges the rod away from the handle, overcoming the thrust of the spring 15, the arms 17 being retracted and releasing the weight 20 which moves to abut a stop 25 and emit a sound by which a watcher knows if the ball has been hit at the moment of greatest angular velocity of the club. The initial compression of the spring 15 may be varied by screwing the member 11. into the cup 12. In a modification the ring 20 is automatically returned to abut the stop 21 by a spring and the rod 13 has a guiding extension passing through an aperture in the end of the closing cup 12.
