Title: Improvements in or relating to photographic reproduction by means of a phosphorescent medium
IPC: G03C5/08
Filed: 1920-07-30
Abstract: 160,739. Christensen, J. H. March 25, 1920, [Convention date]. Reproduction by means of a phosphorescent medium.-Relates to a process for reproducing prints or photographs by means of a phosphorescent medium in which the action of red light in destroying the phosphorescence of the medium is utilized. The transparent phosphorescent screen or sheet is placed in contact with the print or photograph and illuminated or acted upon by coloured light. The sheet is subsequently placed in contact with a sensitive film to produce an image of the print or photograph. The translucent phosphorescent sheet may be coloured or the phosphorescent medium itself may be coloured. In preparing a translucent sheet the phosphorescent material is comminuted by mixing it with liquid and shaking it up with glass balls. The comminuted mixture is mixed with gelatine and glycerine and poured on to a glass plate covered with a film of rubber. After the phosphorescent material has settled and the film solidified a coloured collodion coating is applied and dried, after which the gelatine and collodion films are together stripped off the glass plate, and the phosphorescent surface exposed to strong light to render the material active.

Title: System for analysing electric signals recorded magnetically on a wire or tape
IPC: G01R13/04
Filed: 1951-10-01
Abstract: 688,816. Magnetic recording and reproducing apparatus. WEIBULL, E. H. W. Oct. 1, 1951 [Oct. 25, 1950], No. 22827/51. Class 40 (ii) [Also in Groups XXXVI and XL(b)] Apparatus for analysing electric signals previously recorded magnetically on a wire or tape which is movable from one magazine to another to traverse a magnetic head whose output passes through a frequency-selective filter to a cathode ray oscillograph display, comprises an electromechanical device whereby a selected length of the wire or tape is caused to perform a repeated periodic movement relatively to the head, whose output is displayed on the C.R. oscillograph against an expanded synchronized timebase. Fig. 1 shows a wire tape 6 on which signals to be examined are magnetically recorded, traversible by rotary bobbins 8, 9 round the periphery of a drum 4 carrying a magnetic head 7 whose airgap embraces the wire and whose output is connected through slip rings to a frequency-selective filteramplifier 20 feeding the Y plates of a cathode ray tube 23. As the wire is traversed, the signals selected from the recording deflect the C.R.T. trace in the Y direction until an indication of interest is displayed when the traverse is stopped and the variable speed motor 1 is started to drive the shaft 3 and rotate the drum and the magnetic head round the encircling portion of stationary wire. Simultaneously a circular resistance element 33 energized through further slip rings from a voltage source E is rotated by the drive shaft past a contact 27 which picks off a sawtooth timebase voltage energizing the X plates of the C.R.T. to repetitively display the signals recorded on the selected length of wire against an expanded synchronized timebase. The repetition speed is variable by the motor control knob 2 and the position of the trace is adjustable by a knob and pointer 31 rotating through a worm drive the loose disc 34 carrying the brush 27. In a modification Fig. 2 (not shown) the selective filter-amplifier is embodied in a commercial cathode-ray oscilloscope having an internal timebase synchronized by impulses derived from a brush rotated by the driving shaft to periodically engage a contact on the periphery of a loose disc, which is manually rotatable to adjust the trace position. Fig. 3 shows a further modification wherein motor 1 rotates the bobbins 8, 9 by bevel gears driven from a mechanical control unit 55 such that the speed and direction of rotation is adjustable by a knob 56. and when an indication of interest is displayed the drive is adjustable by knob 57 to oscillate a section of the wire encircling the drum 4 backwards and forwards past the magnetic head, which remains stationary. The circular resistance element generating the repetitive sawtooth timebase is rotated from the bobbin drive through a variable speed transmission unit controlled by a knob 69. The record wire may be looped to completely encircle the drum.

Title: Improvements relating to seismographs, and applicable to other measuring instruments
IPC: G01V1/18
Filed: 1928-08-09
Abstract: 323,552. Anglo-Persian Oil Co., Ltd., and Jones, J. H. Aug. 9, 1928. Vibrations, indicating, recording, and registering. - Small displacements such as earth movements or changes in minute electric currents or in the loading of weighing apparatus are indicated or recorded by the use of a mirror attached to an element suspended in a direction transverse to a magnetic field which varies appreciably from point to point so that by the relative displacement of the element or the magnet system, it takes up a position substantially tangential to the lines of force and rotates an amount proportional to the displacement or current. The device is applicable to a seismograph, oscillograph, or a spring or other weighing-balance. As shown in Figs. 1 and 2 applied to a seismograph a magnet system comprising a magnet e, windings f and adjustable pole pieces e<1> is carried by a screw g adjustable by means of a nut g<1> in a mounting d supported on a screw c carried in brackets b<1> on a platform b on a support a. An extension d<1> on the mounting d carries an adjusting screw d<3> and is provided at the opposite end with a spring buffer d<4>. The iron armature i of the magnet carries a mirror and is suspended by a phosphor-bronze ribbon or wire k from supporting arms l on the pendulum arm m of the seismograph. The mirror deflects a beam of light on to a scale or moving sensitive surface. In a modified form of magnet system suitable also as an oscillograph the magnet, &c. is carried on a platform n, Fig. 3, supported on posts n', n<2>, n<3>, and adjustable by means of pivoted lever devices o, o<1> and screws p, p<1>, mounted in brackets at the side and rear of the platform. In the application to an oscillograph the magnet is fitted with soft iron pole pieces and the magnetizing coils are connected in series so that a current flowing through the coils weakens one pole and strengthens the other in order to distort the magnetic field.

Title: Backward wave converter tube with double conversion
IPC: H01J25/38
Filed: 1962-06-15
Abstract: 1,004,884. Frequency changing circuits. STANDARD TELEPHONES & CABLES Ltd. June 15, 1962 [June 20, 1961], No. 23123/62. Heading H3F. In a backward wave tube mixer in which the electron beam is velocity modulated by an input section receiving a signal and by an oscillator section, the modulations mixing electronically along the beam to produce a difference frequency, means are provided for producing a further modulation in said beam to mix electronically along the beam to produce a second difference frequency. As shown in the Figure an electron beam 3 from gun 2 is velocity modulated by an R.F. input signal from source 7 travelling along helix 5 and interacting with the electron beam. A second helix 6 is dimensioned such that it oscillates for the value of the beam current at a frequency dependent on the applied voltage which oscillations modulate the beam 3 in accordance with its frequency. The two modulations mix electronically along the electron beam and a resultant difference frequency signal is obtained. In order to obtain an output I.F. signal compatible with usual I.F. applications a second frequency conversion is performed within the electron beam by coupling a source of signal 8, having a frequency different from the input and oscillator frequencies, to helix 6. The electron beam is removed at the collector 4 through tuned circuit 9 and coupled to a utilization device 12, part of the I.F. signal being monitored by A.F.C. circuit 13 to adjust the frequency of source 8 and so keep the I.F. constant. By means of a switch 14 the source 8 may be coupled to the gun end of helix 5 or 6 or to the gun 2.
