Abstract: 1,227,603. Photographic materials for printing plates. POLYCHROME CORP. Feb.14, 1969 [Feb.29, 1968], No.9926/68. Heading G2C. A photo-sensitive material for use in producing lithographic plates comprises a support with at least a hydrophilic surface coated with a lightsensitive layer which on exposure and processing produces a positive-working plate and overcoated with a layer which is (a) a silver halide emulsion capable of being processed to give a positive silver image, (b) an image-receiving layer containing development nuclei or (c) a layer containing a photo-sensitive or photo-conductive compound which after exposure may be physically developed in the presence of a silver salt to yield a direct positive image. Specified positive-working light-sensitive layers are naphtho- or benzo-quinone diazide sulphonic or carboxylic acid amides or esters, as a condensation product of a phenol-formaldehyde resin with a naphthaquinone diazide as in Specification 1, 227, 602, a diazo resin treated with potassium ferrocyanide as in Specification 947, 760, a novolak resin and a diazonium salt as in Specification 944, 884 and a novolak resin with a diazonium reineckate salt as in Specification 1,080,153. Specified silver halide emulsions are prefogged emulsions as in Specifications 873, 937 and 875, 887, emulsions which are developed by the photosolubilization process aa in Specifications 1, 031, 901-3 or emulsions which produce internal images as in Specification 645, 877. Alternatively, layers containing photo-sensitive or photoconductive compounds which on exposure and development produce silver images e.g. as in Specifications 1, 064, 095 and 1, 076, 777-9 may be used. In the examples, a grained aluminium support is coated with a naphthaquinone diazide resin layer and overcoated with a high contrast silver halide emulsion. This is image-wise exposed to produce a latent silver image which is developed and bleached in an acidic potassiumdichromate bath. The material is now fogged by exposure to light and the latent image developed to give a reversal positive silver image. The material is now exposed to ultra-violet light and the silver image layer and exposed areas of the diazide resin layer removed with an alkaline buffer solution to have a positive working lithographic plate. A layer of novolak resin may be applied between the diazide resin layer and the emulsion.

Abstract: 1,257,308. Multiplex radio signalling. GENERAL ELECTRIC CO. Ltd. 17 April, 1969 [17 April, 1968], No. 18129/68. Heading H4L. In a signalling system in which data is transmitted by phase modulation of a carrier wave, an auxiliary or supervisory signal is-transmitted by frequency modulation of said carrier, the highest frequency component of the -auxiliary signal being of lower frequency than the data bit rate, such that the maximum phase shift of the carrier due to the frequency modulation during any one pulse interval of the data transmission is much less than the minimum step phase shift utilized in transmitting the data. Transmitter, Fig. 2.-Data signals in dibit form, from sources 5 are modulated on to four carrier waves by respective phase modulators 4 providing four -possible phase shifts of -the carrier, the carriers being derived from sources 6 via frequency-modulators 7 and filters 8. Auxiliary signals from sources 9 are supplied to the modulators 7 so that one auxiliary signal is modulated on each carrier. Alternatively one auxiliary signal may be transmitted as a differential modulation of a pair of carriers. The outputs of the phase modulators 4 are supplied via filters 10 to an amplifier 11 where they are combined for transmission by radio. Repeater, Fig. 3.-Each aerial 12 is arranged to receive -and transmit both vertical -and horizontally polarized signals so that each repeater can transmit and receive two groups of four carrier frequencies in either direction. Received signals are supplied via a circulator 13 and filter 14 to a mixer 15, the output of the mixer 15 being supplied via an I.F. amplifier to a mixer 17 providing a signal for retransmission via filter 21, amplifier 22 and circulator 23. An oscillator 18 provides local oscillations for the mixer 17 and after mixing at 19 with output of an oscillator 24 provides local oscillations for the mixer 20. An auxiliary signal may be transmitted to the terminal station by frequency modulating the output of oscillator 24 so that it is modulated on all four carriers. Receiver, Fig. 4.-The auxiliary signals are recovered frequency-multiplying all the carrier signals by four so that the phase-shifts representing the data signals become multiples of a complete cycle and have no effect. The resulting signals are supplied via filters 26 to frequency dividers 27 where the original carrier frequencies, modulated in frequency but without the phase shift modulation, are recovered and are supplied to control the frequency of oscillators 28. Low frequency signals carrying the frequency modulation may be derived by mixing the output of each oscillator 28 with unmodulated carrier signals or in the case of differentially modulated carriers by supplying the differentially modulated carriers to a mixer 33 and applying the output of the mixer to a frequency discriminator 34. Synchronous detectors 29 recover the data signals which are regenerated at 30 and separated into individual pulse trains at 31.

Abstract: 1,257,505. Magnetrons. MATSUSHITA ELECTRONICS CORP. 13 June, 1969 [21 June, 1968 (2); 7 Aug., 1968 (2); 13 Sept., 1968; 30 Sept., 1968], No. 29990/69. Heading H1D. A magnetron having an upwardly projecting insulator vessel contiguous to its upper polepiece and enclosing the cathode lead, and a downwardly projecting insulator vessel contiguous to its lower polepiece and enclosing an antenna extending from the magnetron resonant cavity, includes a permanent magnet having an axial hole of a diameter exceeding that of the upper insulator vessel and disposed such that that vessel is at least partly within the hole, with an interstice therebetween, the lower end surface of the permanent magnet being coupled with the upper surface of the upper magnetic polepiece either directly or through a yoke member. As shown in Fig. 3, the metal envelope portion 2 of the magnetron has welded thereto a stack of cooling fins 9 through the passages between which air is forced from the intake port 7 to an output port on the opposite side of the assembly. Insulator vessels 3 and 4 house the cathode lead 16 and output antenna 5, vessel 3 being mounted within the axial hole 11 of the cylindrical or conical ferrite permanent magnet 10, the upper end of which is coupled by the high permeability shield 12 to the magnetron lower polepiece, plate 13 of the shield being provided with holes 15 for mounting on an electronic range. In this embodiment the magnet 10 is slotted at 20 to provide a passage for cooling air to pass from the additional input port 18 into and upwardly along the annular space between the magnet and the vessel 3, whereby they are both cooled and the vessel is protected from mechanical damage. In a modification of this arrangement (Fig. 5, not shown) the magnet 10 is a complete annulus and of cylindrical shape, the slot 20 being formed in a conical magnetic yoke (21) interposed between the magnet and the magnetron upper polepiece. In the arrangement of Fig. 6 which employs a cylindrical magnet 10, magnetic shortcircuiting of the shield 12 to the magnetron upper polepiece is reduced by the use of permanent or electromagnets 30 of opposed polarity. In a further embodiment (Fig. 7, not shown) a cylindrical permanent magnet (100) mounted on the plate 13 constitutes the outer shield of the device, an inner cylindrical yoke (102) coupling an end disc closing the magnet to the magnetron upper polepiece.
