Title: Improvements in thermionic valve circuits employing reaction
IPC: H04B1/16
Filed: 1936-10-28
Abstract: 483,504. Valve circuits. MURPHY RADIO, Ltd., and BALEAN, J. H. Oct. 28, 1936, No. 29349. [Class 40 (v)] To maintain reaction substantially constant over a wide range of frequencies, the reaction coil or reaction circuit is shunted by a reactance of which the accoptance varies with frequency in the same manner as the reaction of the valve would vary with frequency in the absence of the shunt. In Fig. 1, reaction is obtained by inductance 5 and is controlled by condenser 6. The circuit 5, 6 is shunted by the compensator 7, 8, 9 which comprises two tuned circuits which present two minima of impedance with a maximum between them. The valves of the components are chosen so that the minima occur at or near the high frequency end of the two ranges of wave length for which the receiver is tunable and the maximum is at the low frequency end of the short or medium wave range. High tension may be applied at any convenient point and is connected through high impedance 10 so that the compensator is not shunted by condenser 11 and transformer 12 which supply the next stage. Several arrangements of compensator are shown connected between anode and cathode or between grid and cathode as shown in Fig. 7. If the shunt is to be used in a circuit which is tuned over a number of wave ranges, the notwork should have one fewer rejector resonances than the number of ranges with an acceptor resonance on each side of each rejector resonance. The effect of the compensator may be enhanced by the provision of an additional impedance such as inductance 21, Fig. 7. The invention can be used to cause an oscillator to give constant voltage at all frequencies.

A signal s, Fig. 2, consisting of a facsimile signal from an image on a rotating drum 2 provided by a photo-electric transducer 4, is amplified at 5 and converted into digital form, Fig. 2b, at 6, the coded pulses from converter 6 being supplied to a shift-register 7 under the control of pulses t supplied via contact b of switch 9 from a generator 12. In order to compress the coded pulses in time so that they may, for example, be transmitted in the horizontal or vertical flyback interval of a television signal, the pulses are read out of the shift register, Fig. 2e, at a higher speed by pulses d supplied via contact m of switch 9 from a generator 10. The changeover of switch 9 is controlled by pulses c, of duration a little less than the interval between pulses t, which are derived via a frequency-divider 11 from generator 12. At the receiver the compressed signal is expanded to its original length by a similar shift register. In a modification, a separate shift register is used for each digit of a coded signal sample the shift registers being operated in parallel and controlled as before, their outputs being converted to serial form. Alternatively, the outputs of the shift registers may be reconverted to an analogue signal which is a compressed version of the original.

Classes 97(1) and 98(1) A lens mount attachable within a cylindrical opening in a camera comprises two relatively coaxial lens mount members one having means for holding it against axial movement in the opening, and a lens optical unit axially moved for focusing by such relative movement, one member carrying two differently graduated focusing scales (e.g. in feet and meters) and the other member carrying two alternative keying elements, angularly spaced corresponding to the two scales and co-operating in two alternative angular positions with a keying element in the camera to allow either scale to co-operate with a single indicator on the camera. As shown one member B has a groove B 4  engaging spring- urged balls in the camera opening and diametrically opposed slots B<SP>2</SP> engaging a projection on the camera wall in one of two alternative positions to bring one of the scales D<SP>2</SP> on the second member D adjacent the indicator. The member D engages a fine thread C<SP>1</SP> within the member B and has a coarse thread K<SP>1</SP> engaging the lens unit E the latter having slots L2 engaging keying pins L fixed to the member B. Thus by rotation of member D relative to member B the pins L, preventing relative rotation between member D and unit E causes relative axial focusing movement of the latter. Alternatively axial movement may be effected solely by the thread C<SP>1</SP>. In a modification the inner member D is held against rotation by co-operation of a slot therein with a pin fixed in the camera housing whilst the member B carries the distance scales and is rotatable relative to the camera.

Title: Improvements in the decoration of tiles or like articles
IPC: B28B11/04
Filed: 1933-10-28
Abstract: 408,894. Printing processes and apparatus. OXVAR, Ltd., 3, Lower Regent Street, London.-(Assignees of Casto, L. V.) Oct. 28, 1933, No. 30018. Convention date, Oct. 28, 1932. [Class 100 (ii).] Tiles or the like are decorated to produce " Faience " effects by printing from a printing plate or roll carrying a design which has an area many times larger than the individual tile, the design varying throughout its area, and from the printing-plate different portions of the designs are transferred to individual tiles, whereby a large number of tiles bearing different designs are produced from the same plate or roll. An offset machine of known kind is used and an intaglio printing-plate which is prepared photographically so as to have a plurality of areas each of which has a different tonal range is applied to a printing-roller 70 with which co-operates an offset roller 60 and an impression roller 51, all of which are driven by a motor 100 in unison with a conveyer band 30 by means of which the tiles T are carried through the machine. In order to print a large number of tiles with different designs, the circumference of the roller 70 is not an exact factor of the distance between the tiles, so that a number of work-holders 40, each carrying four or more tiles abreast, can pass between the rollers 51, 60 before the designs are repeated. Further to increase the number of tiles printed before repetition, the holders 40 are displaced laterally after the maximum number of variations are obtained in the longitudinal direction without repetition. The holders 40 are formed with a number of pads over which the downwardly extending sides of the tiles extend, and each holder is placed by hand in front of projections 33 on the conveyer chains. As the holders 40 approach the printing position they are engaged by guides 150 with flared sides 153 which guide the holders into engagement with the sides 154 of the guide 150. The guide 150 is moved to different lateral positions so as to cause the tiles to engage a different lateral part of the roller 60 when the maximum longitudinal variations have been obtained for one lateral position. The guide 150 is moved by an eccentric 164 which is rotated intermittently by studs on the conveyer engaging radial arms on the shaft of the eccentric. A spring stud engaging recesses in the bottom of the guide 150 holds it in the desired lateral position. Two or more machines may be combined for printing two colours on each tile, and this permits of a much larger number of tiles to be printed in different designs without repetition.
