Title: Modulation systems for carrier wave signalling
IPC: H03F1/06
Filed: 1941-01-02
Abstract: 543,924. Valve modulating circuits. STANDARD TELEPHONES & CABLES, Ltd. Jan. 2, 1941, No. 75. Convention date, Jan. 9, 1940. [Class 40 (v)] In a grid modulating system, distortion due to the flow of grid current at the peak of the modulating wave is prevented or minimized by connecting a power-absorbing device (e.g. a diode valve) across the carrier source, and providing means for decreasing its power absorption in response to increasing grid current. In Fig. 1 the carrier source 3 and audio source 2, are transformer coupled in series in the grid circuit of the valve 1, the grid being biased by a battery 10. A diode 15 is connected across the carrier secondary 8 in series with a battery 16 of such polarity and voltage that carrier power is absorbed in the diode during periods when no grid current is flowing. At the modulation peaks grid current flows and puts a further load on the carrier source. Owing to the regulation of the source, its output voltage falls until the diode is no longer conductive, and the total load on the carrier source is maintained substantially constant. The two sources 3, 4 may be connected in parallel (Fig. 2 not shown), and the battery 16 replaced by a condenser-shunted resistance (Fig. 3 not shown). The circuit of the diode 15 and battery 16 may be inductively coupled to the secondary 8 (Fig. 4 not shown). In Fig. 6 the diode is replaced by a triode 15A, the grid of which is biased by a battery 16 and by a resistance 19 through which flows the grid current of the main valve 1. The battery 16 may be omitted and a condenser-shunted resistance inserted in the cathode lead of the triode 15A (Fig. 7 not shown). The voltage across the resistance 19 may be amplified in an additional valve which is cathode-coupled to the grid of the absorption triode 15A (Figs. 8 and 9 not shown). The circuit may be adjusted to give undercompensation or over-compensation for the falling off of carrier voltage when grid current is flowing. Over-compensation is desirable when the audio source has poor regulation which tends to flatten the audio-voltage peaks when loaded by grid current. The circuits may be used for demodulation and for frequency changing in radio receivers.

Title: Improvements in or relating to electrostatic image copier
IPC: G03G15/05
Filed: 1964-01-01
Abstract: 995,816. Electrostatic image copying employing scanning. DICK CO. A.B. Jan. 1, 1964 [April 1, 1963], No. 88/64. Heading H4F. In an electrostatic image copier employing scanning a charge pattern corresponding to a line of the image is laid down by a line array of electrodes 36A, 36B, 36C &c., Fig. 2, which are retained in holes in an insulator 34 and each of which is associated with a photo-conductive (e.g. cadmium sulphide) element 38A, 38B, 38C &c. which connects the electrode with a translucent conductive layer 40. A video signal representative of an original image to be copied is derived through an amplifier 30 from a photo-electric cell 24 which scans the image and is applied to layer 40, whilst the photo-conductive elements are rendered conductive in succession by light from a constant source which is scanned along the array of elements in synchronism with scanning of the image. A source of radio-frequency oscillation is applied to a backing electrode 26B and the medium, e.g. paper, on which the record is to be made is traversed in the gap between electrodes 26B and the array of electrodes 36. In one apparatus, Fig. 3, the original image 10 remains stationary and is located adjacent a constant light source 50. The image is scanned in a succession of vertical lines by a rotating mirror assembly 52 which co-operates with a photoelectric cell 54 traversed horizontally by a lead screw 56. At the same time mirrors assembly 52 also scans the light from source 50 over the array of photo-conductive elements in the electrostatic copier 62 so that they are rendered conductive in succession in synchronism with the scanning of each line of the original image. In another apparatus, Fig. 2 (not shown), the original image is carried by a drum which is rotated to introduce one component of scan. The recorded electrostatic image is rendered visible by known processing methods. The image scanning photo-electric cell may have a desired spectral response and the desired video signal may be processed in suitable circuits to obtain a desired signal amplitude, polarity and linearity.

Granted: 1996-03-31
Abstract: In order to enrich natural gas or other hydrocarbon gases with hydrogen, thus reducing the carbon content and thereby achieving a reduction or elimination of the discharge of carbon dioxide during combustion of the gases, a pyrolytic process is conducted in the feed stream for the natural gases or hydrocarbon gases which are to be burned. The gas is passed through a reactor in which it is decomposed at least partially into a carbon constituent and a hydrogen constituent. The carbon constituent is removed to a desired level. Any remaining constituent together with the hydrogen constituent is conveyed to the combustion process while the removed carbon constituent is conveyed out of the process for separate application. The pyrolytic process can be carried out on the entire stream or only on a partial stream.

Title: Improvements in or relating to photographic cameras
IPC: G03B7/06
Filed: 1958-01-02
Abstract: 878,153. Photographic cameras DECKEL, H., and DECKEL, F. W. Jan. 2, 1958 [Jan. 12, 1957; May 17, 1957; Sept. 27, 1957], No. 182/58. Class 98(1) In a photographic camera, the shutter speed and diaphragm aperture are set by actuation of the sun wheels of a differential gear, the cage of which is rotatably coaxial with the optical axis of the camera and carries a planet wheel rotatable about an axis perpendicular to the optical axis. Preferably, the camera is provided with a built-in photo-electric exposure meter having a follower operatively connected to the cage of the differential. As shown, a sun wheel 24 is connected by arm 26 to a shutter speed adjusting ring 27 carrying an index 74 which reads on a stationary shutter speed scale 72. Sun wheel 30 is connected to iris diaphragm blades 20 and depth of field pointers 32. The diaphragm aperture is adjusted by turning cage 40 by knob 44 to bring follower 60 opposite exposure meter pointer 64 while shutter speed ring 27 is retained by a click or like releasable stop. The exposure meter is corrected for the film speed by means of releasable coupling 46, 48 and film speed scale 49. No indication of the change of diaphragm aperture except movement of pointers 32 is given. Subsequent movement of shutter speed ring 27 rotates planet wheel 38 to bring about compensating variations in the diaphragm aperture without disturbing cage 40 and follower 60. In another form, sun wheel teeth project radially inwards from shutter speed and diaphragm aperture scale rings and in an interchangeable lens mount a pinion corresponding to 52 remains on the camera while meshing inwardly directed teeth are provided on the differential cage which is carried in the lens mount. The cage is rotatable by means of a knob mounted on the camera body. As applied to a twin lens camera (Fig. 12-17, not shown), the cage is journalled on the shutter housing and the sun wheels are journalled on the cage and have internal teeth meshing with a planet wheel and external teeth meshing with scale rings rotatable about the finder objective. A pinion reverses the drive to the diaphragm aperture scale ring so that when the exposure value is invariant and the cage stationary both scale rings rotate equally in the same direction. Specification 798,038 is referred to.

Abstract: 605,766. Embossing processes. BROGAN, W. L., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Jan. 4, 1946, Nos. 368 and 3260. [Class 100(ii)] A process for embossing unsupported sheets of, or textile fabrics coated with, polyvinyl chloride or a copolymer thereof, on normal plate embossing machinery, employs plate temperatures of at least 170‹F., with an appropriately short dwell, a sheet of regenerated cellulose being interposed between the embossing plate and the sheet or fabric to be embossed. Two examples are given. Cotton fabric coated with a composition consisting of equal parts of polyvinyl chloride, tricresyl phosphate and iron oxide pigment is fed into an embossing press with a film of regenerated cellulose 0.0015 inches thick between the coating and the engraved platen which is heated to 220‹F. On release of the pressure, the coated fabric and the film adhering to it are withdrawn. Successive portions are embossed in turn and the fabric is then batched up with the film and allowed to cool, when the film is separated without difficulty from the embossed fabric. A polyvinyl chloride sheet material 0.0020 inches thick made by calendering a mixture of polyvinyl chloride 100 parts by weight, tricresyl phosphate 42 parts by weight, and iron oxide pigment 8 parts by weight, is embossed in a similar manner, using a film of regenerated cellulose 0.0015 inches thick between the sheet and the engraved platen which is heated to 220‹F. The whole is allowed to cool before the film is removed from the embossed sheet.
