Creasing; folding paper.-Apparatus for applying corner stays to boxes is provided with a device comprising grooving-members between which the paper strip is guided so as to form an accurately positioned longitudinal groove or crease therein, and a co-operating folding channel which doubles the strip along the groove or crease as it is drawn through the device. In the arrangement shown an upper grooving-roller B is mounted in a frame D carried by a pivot pin d in the body A and is pressed on to a lower grooving-roller B<1> by springs d<1>, the upper roller being lifted to release the strip C by a cam E mounted on the axle of the roller B and engaging the frame D; the cam is operated by a handle e The body A extends forwards to form a channel A<1> the sides a of which approach each other and increase in depth to the end a<2> where the strip emerges in a completely doubled form. To ensure the strip being grooved centrally it passes between lateral guides F simultaneously adjustable by a cone G to the width of the strip; the cone is centrally disposed and is vertically adjustable by nuts g<1>, the guides being pressed against the cone by springs f<1>. A cam or right and left handed screw may be used in place of the cone G.

Patent GB-644926-A (GB)
Title: Improvements in or relating to electric pulse generators
Inventor: HOUGH GEORGE HUBERT
IPC: H01J17/48
Filed: 1947-11-13
Abstract: 644,926. Thermionic and like distributers. STANDARD TELEPHONES & CABLES, Ltd. Nov. 13, 1947, No. 30199. [Class 40 (iii)] [Also in Groups XL (a) and XL (c)] A pulse generating circuit comprises a cold cathode gas-filled electric sequence discharge tube (see Group XL (a)) of the type described in Specification 639,827. The tube comprises an anode 1, cathodes 2-11 and triggering electrodes 12-20, an auxiliary electrode 21 forming the trigger for the first cathode 11. The potential of the source 25 is insufficient to initiate a discharge across any gap, but is sufficient to maintain a discharge struck by any other means. The potential of source 26 is such that when added to that of source 25 it is sufficient to strike and maintain permanently a discharge between priming electrodes 22 and 23. The anode 1 is connected to ground through a diode 60, which may be replaced by a germanium or other rectifier, and operates to stabilize the discharges. Cathode 2 is connected through a resistance 27 to a common conductor 28 which is connected to ground through the primary winding of an output transformer 29. The remaining cathodes 3-11 are connected to conductor 28 through parallel resistancecapacity circuits. Cathodes 3-11 and the auxiliary electrode 21 are respectively connected to trigger terminals 48-57. A positive pulse applied, for example, to trigger terminal 53 initiates between electrodes 17 and 7 a triggering discharge which causes the main gap between anode 1 and cathode 7 to be fired. The potential of electrodes 7 and 16 now rises from zero at a rate determined by the time constant of the associated resistance-capacity network until the trigger electrode 16 reaches a sufficiently high potential to fire the triggering gap between electrodes 16 and 6. The process repeats along the array until the last gap, between anode 1 and cathode 2, is fired. Eac time a main gap is fired the increase in current flowing through the primary winding of transformer 29 produces an output pulse at the secondary winding terminals 58 and 59. In an application of the circuit to the production of trains of time-modulated pulses for a multichannel pulse communication system, regularly repeated triggering pulses are applied to terminal 57 and the modulating speech waves for the respective channels are applied to terminals 62 and 48-56. Each time one of the cathodes is fired, an output pulse is obtained from transformer 29 and the time at which the cathode is fired and therefore the time of production of the pulse will depend on the instantaneous voltage of the corresponding signal wave.

[Also in Division H1] In a multi-colour luminescent screen in which e.g. the red elements comprise a rare earth orthovanadate phosphor, YVO 4  : Eu, or an yttrium oxide phosphor, Y 2 O 3  : Eu, the luminance efficiency of the red elements is matched with that of the blue and green elements by associating with the layer comprising the red elements a layer comprising red emitting "luminance control" phosphor material comprising an activator, such as Zn (PO 4 ) 2  : Mn or (Zn Cd) S : Ag, or not comprising an activator, such as Zn 3  (PO 4 ) 2 . Suitable proportions for obtaining a desired luminance are given and in two examples the coating procedures are specified. The red phosphor elements may be formed by sedimentation from a single suspension containing both phosphor materials or from two suspensions used in succession, each suspension containing one phosphor material. Preferably the luminance control phosphor material is away from the substrate and the weight ratio between the main phosphor material and the luminance control phosphor material lies between 1: 3 and 4: 1. An overlying photosensitive resin which is hardened by actinic light is used as a binder as well as to remove excess material.

Abstract: 709,511. Television. HAZELTINE CORPORATION. Dec. 1, 1952 [Dec. 18, 1951], No. 30430/52. Class 40 (3) In a dot-sequential colour television system the (spurious) dot structure resulting from the sampling process of the receiver is reduced by increasing the frequency of the received colour sub-carrier wave and the frequency of sampling. Fig. 1 shows one embodiment in which the frequency of the received colour sub-carrier (3.5 Mc/s) derived from filter 30 is increased to 10.5 Mc/s by modulation in 34 with the second harmonic of an oscillator 36 synchronized with the colour sub-carrier by means of synchronizing signals from separator 25. The 10.5 Mc/s output of modulator 34 which is selected by filter 35, is combined with the 0-4 Mc/s brightness signal from video amplifier 16 and fed to the control electrode of a single-gun tricolour image reproducing tube 18 the single beam of which (in addition to the normal rectilinear scanning effected by coils 21, 22) is given a rotary motion (to select the required colour phosfor on screen 24) by means of coils 19, 20 fed from phase quadrature generator 40 to which a 10.5 Mc/s signal, derived by multiplication of the 3.5 Mc/s signal of oscillator 36, is fed and the cathode of which is keyed by a 31.5 Mc/s signal derived from oscillator 36 via frequency multipliers 38 and 39. In a second embodiment, Fig. 2 (not shown), which employs a tri-gun tube in place of the single-gun tube 18, so that generator 40 and coils 19, 20 are not required, the second frequency multiplier 39 is replaced by a gating device which supplies three gating signals occurring at 10.5 Mc/s and having a 120 degrees relative phase displacement to the respective gun cathode electrodes. In another embodiment, also employing a tri-gun tube, the combined outputs of amplifier 16 and filter 35 are, fed to a 10 5 Mc/s three-phase (120 degrees) sampling device which supplies the individual gun cathodes the control grid being at earth potential, Fig. 3 (not shown). Specification 689,821 is referred to.
