Patent GB-1204061-A (GB)
Title: Electrophotographic print-out machine
IPC: G03G21/14
Filed: 1968-02-14
Abstract: 1,204,061. Electro-photographic apparatus. ADDRESSOGRAPH-MULTIGRAPH CORP. Feb.14, 1968 [Feb.20, 1967], No.7319/68. Heading G2H. An electro-photographic apparatus receives signals from a data signal source 12 to produce images at an exposure station on light sensitive copy sheets 14, fed in accordance with a predetermined programme along a path through the station, and means are provided for detecting failure of the sheet to move in accordance with the programme and to provide a signal indicating that the apparatus is not in a condition to process a copy sheet. The signal source 12 supplies signals to a cathode ray tube 16 to produce images on the sheets 14 fed from a stack or cut from a web. A clutch 18 between a drive motor 20 and rollers 22 controls the feed of the sheets to a corona charging station 24. Drive rollers 30, 32, 34 are driven intermittently by a motor 26 from a power supply 28 controlled by the signal source 12 in synchronism with image producing signals fed to the cathode ray tube 14. A detecting station 38 having photo-cells 156 and 158 arranged in a line transverse to the path of sheet movement detect skewing of the sheets such skewing being indicated by illumination of a lamp 188. A jam detecting circuit 42 has a photo-cell 52 illuminated twice for each rotation of a gear 46 by a lamp 50, thus providing pulses counted by a circuit 42. A lamp 244 is illuminated if the sheet does not reach a detecting station 60 at the proper time while a gate 144 inhibits a gate 146 to prevent transfer of control to data source 12 and prevent additional copies being fed from the supply. Rollers 54, 56 are continuously driven by a drive motor 58 assuming no jam occurs to feed the sheet 14 carrying a latent electrostatic image to the station 60 and developer station 70. A photocell 212 detects the arrival of a sheet at the station 60. A photo-cell 250 detects the arrival of sheet at a station 74. Failure of a sheet to arrive at station is indicated after an appropriate time delay by illumination of a lamp 272. As the copy sheet leaves a fusing station 76 it intercepts a beam of light to a photo-cell 274 at detecting station 88. If the sheet does not intercept the beam by the time a circuit 280 times out, a lamp 300 provides a visible indication and through gates 124, 144 prevents further signals being fed to cathode ray tube 16.

Abstract: 141,681. Chantiers et Ateliers A. Normand. April 17,1919, [Convention date]. Void [Published under Sect. 91 of the Act] Valve-gear.-The fuel-injection valve is constructed without any packing-gland, the valve 4, the actuating- lever 10, and the closing- spring 6 being enclosed in the valve casing.

Title: Improvements in electrical controlling apparatus
Inventor: REDDING ROBERT JAMES
IPC: A01B35/02
Filed: 1955-03-15
Abstract: 803,273. Automatic control systems. EVERSHED & VIGNOLES, Ltd. March 1, 1956 [March 15, 1955], No. 7548/55. Class 38 (4). [Also in Groups XXXVIII and XL (c)] In an automatic control system for, e.g., liquid level or pressure, a force P proportional to the variable controlled is applied to a pivoted arm 2 and is opposed by a force representing the datum setting. This force is derived by passing a reference current through coil 5 from a source stabilized as disclosed in Specification 723,826. Coil 5 moves in the field of a permanent magnet 6. Lack of balance closes contact 16 or contact 17 to increase or decrease the bias on valve 22, and so change the bias on valve 30 in the reverse sense due to the voltage change across resistor 34. Valves 22, 30 and supply rectifiers 23, 31, form a bridge which when unbalanced provides a signal between leads 40, 41 which is applied via a " power receiver " (to restore the liquid level &c.) to the coil 5 to rebalance the arm 2. The current flowing is proportional to the deviation of the variable and is indicated at E. Variable resistors 42, 44 adjust the proportional band setting of the system. The total current in coil 5 is proportional to the measured valve of the variable and is indicated at MV. It is stated that the input force P may be derived from a Bourdon tube pressure gauge or from a float, measuring liquid level; that the " power receiver " may be the pneumatically-controlled valve shown in Specification 704,885; and that integral and differential components may be added to the proportional control signal as disclosed in said Specification. It is also stated that the " desired value " current and " error " current may be applied to separate coils instead of the single coil 5. Specification 688,464 also is referred to.

Title: Improvements in television camera equipment

Abstract: 717,263. Television transmitters. RADIOINDUSTRIE. March 25, 1952 [March 31, 1951], No. 7645/52. Class 40 (3) In the circuit of a television transmitter comprising a camera tube of the type having a photocathode and an image section converting the optical image produced on the photo-cathode to an e ectronic image upon a mosaic storage eectrode, the current flowing in the circuit of the photo-cathode is used to develop a voltage measuring the total light flux incident upon the photoelectrode, this voltage is then either used to effect retroactive-control of an iris diaphragm in the path of the light falling upon the photocathode or applied to a meter to enab'e a controlled manual adjustment of the iris diaphragm to be made. The current flowing in the circuit of the photo-cathode 2 results in a potential being developed at the tapping point 12 of the potentiometer 10. This potential is app'ied to the control grid of a modulator valve 13, the cathode circuit of which is coupled to the heater circuit so that the output from the valve comprises a 50 c/s carrier-wave signal modulated in amplitude in accordance with the signal from the photocathode 2. This output signal is rectified at 22 and applied to cathode fol'ower 26, the output from which is applied either to the meter 39 or to a retroactive servo control system to control the light falling on the photo-cathode through an iris diaphragm.
