Patent GB-998886-A (GB)
Title: Improvements in or relating to high frequency distribution systems
Inventor: HAYWOOD HUBERT
IPC: H04J1/06
Filed: 1962-11-23
Abstract: 998,886. Radio transmitting systems. MARCONI CO. Ltd Oet. 9, 1963 [Nov. 23, 1962], No. 44324/62. Heading H4L. In a high-frequency distribution system, particularly for use in multi-transmitter radio stations, in which carrier drives to the various transmitters are provided by frequency synthesizors fed from a common master oscillator, the frequency distribution is effected by hybrid junctions which ensure that the master frequency continues to be supplied despite local circuit failures, and means are also provided for automatic changeover to a standby master oscillator. As shown, the main master oscillator 1 is arranged to supply a signal via a normally open gate 2 and gate control circuit 3 to block the gate 2A in the output circuit of the standby master oscillator 1A, but if a fault occurs in the master oscillator 1 the gate 2A is opened and the gate 2 blocked via control circuit 3A. The gates 2, 2A supply the single input ports of hybrids 4, 4A, respectively. One output of the hybrid 4 is connected to one of the two inputs of a hybrid 5 and the remaining output is connected to one input of a hybrid 5A, the hybrid 4A being likewise connected to the remaining inputs of hybrids 5, 5A. Thus whichever master oscillator is in use will supply both channels 5 to 8 and 5A to 8A. The output of hybrid 5 is amplified at 6, given a phase shift of 30 degrees at 7 and supplied to the single input of a hybrid 8, the output from 5A, being treated similarly but given a phase shift of 30 degrees in the opposite sense. The outputs of hybrids 8, 8A are distributed to a plurality of points, one only frequency synthesizer 24 being shown, by hybrids 9 to 22 and 9A to 22A, cross-connected as shown, the relative phase-difference of 60 degrees between the two channels ensuring that when the two input signals are present, for example at hybrid 23, the output signal is of equal amplitude to that when only one is present. A switch may be included to select which of the oscillators 1, lA shall act as master oscillator as by modifying the biasing of gates 2, 2A. A modification including an additional standby oscillator is described.

Title: Adhesive transfer image reproduction
IPC: G03G16/00
Filed: 1965-10-22
Abstract: 1,120,602. Printing. RANK XEROX Ltd. 22 Oct., 1965 [5 Nov., 1964], No. 44909/65. Heading B6C. [Also in Division G2] Images, particularly images of high resolution, are produced by bringing a member having an adhesive surface into contact with a member bearing a releasable surface layer, one of the members bearing a deformation image made electrostatically. As shown, Fig. 1, the deformation image 16 comprising minute peaks 18 and minute valleys 17 is formed on an adhesive layer 28 of e.g. polystyrene resin, mounted on a photoconductive layer 26 backed by a conducting layer 27. The releasable surface layer 12 of marking material e.g. carbon black and graphite, is carried by a web 11 of polyethylene terephthalate or other suitable flexible material. By pressing the web 11 against the layer 18 as by a roller 14, marking material is transferred to the raised parts of the image 16 so that a positive image appears on the web, and a negative of the image appears on the layer 28. The latter may be viewed directly or used as a transparency. A deformable photoconductive layer may be used instead of the two layers 26, 28. In a modified arrangement, Fig. 6 (not shown), a layer of releasable marking-material is applied to the deformation image and a flexible web with an adhesive surface is pressed against the image. To form the image 16, the layers 26, 27, 28, comprising a member 15, are supported on an earthed plate 32 Fig. 4, and an electrostatic charge is applied thereto by electrodes 35, 36, connected to a corona power supply 46. Subsequently, or simultaneously, an optical image is projected on to the member from a projector 31 and through an electrically-conductive transparent shield 37 from which the electrodes 35, 36 are suspended. The resulting differential charge on the member 15 causes an image consisting of microscopic peaks and valleys to be formed in the suitably-constituted layer 28. With some materials, the layer 28 may require heat or solvent treatment after removal from the apparatus in order to produce the deformation image.

The throttle valve 22 comprises a sleeve which is movable axially relative to a port 25 in opposition to a spring 22a and is rotated by the engine through gearing 24. The restrictor 19 is defined by the annular space between the sleeve of the throttle valve 22 and a nozzle 21.
