Title: Picture telephone arrangements
IPC: H04N7/14
Filed: 1969-09-25
Abstract: 1276568 Automatic exchange systems; television TELEFONAKTIEBOLAGET L M ERICSSON 25 Sept 1969 [8 Oct 1968] 47355/69 Headings H4F and H4K In a picture telephone system for transmitting text i.e. facsimile or video (face) signals and speech, in which video signals of different characteristics, e.g. different picture repetition frequency, but same bandwidth are transmissible, a signal for controlling the mode of the receiver in respect of the type of video signal being transmitted is sent from the transmitter to the receiver over a channel in the system. The problem, in a limited bandwidth telephone network, of compatibly transmitting either moving pictures, e.g. of a subscriber's face at a high repetition rate and hence a low resolution or transmitting still picutes, e.g. of a page of text at a low repetition rate and hence a high resolution is overcome by synchronously adjusting the modes of the transmitter and receiver with the aid of the control signal sent over an independent channel of the network. The video subscribers are connected over six-wire lines to PBXs which include the necessary high and low frequency both-way links for respectively video and speech transmission. Besides the obvious use of four of the six wires for video and speech, the other two wires are used for transmitting and receiving the control signals. The subsets and/or the PBXs may include the devices for adjusting the picture scanning rate or the picture repetitions rate, e.g. a scan converter comprising a picture tube and camera in series. Between exchanges the video signals may be transmitted in PCM form, a different code being used for pictures having different characteristics. For example in facsimile working short sampling intervals with one bit representing each sampled value may be used whereas for transmitting a face a long sampling interval, with several bits (corresponding to different tone values) may be utilized to represent each sampled value.

Filed: 1976-11-16
Abstract: 1521600 Data processing INTERNATIONAL BUSINESS MACHINES CORP 16 Nov 1976 [31 Dec 1975] 47655/76 Heading G4A The design of a minimally redundant data base to be used by a plurality of applications programs is assisted using a computer programmed to process "local views", defining the individual data bases required by each program, so as to identify the essential associations between the data elements (smallest data references used) present in the entire data base. Associations in both directions between data elements in each local view are identified and classified as "1" type (each occurrence (value) of one element, e.g. Employee has a single associated occurrence (value) of another element, e.g. Department), "M" type (each occurrence of one element may be associated with multiple occurrences of another element, e.g. Dept.- Employee), or "C" type (not all occurrences of one element have associated occurrences of another element, but those that do are "1" type, e.g. Employee-Manager). A data element which has one or more "1" type associations leaving it is classified as a Key and forms a node in a notional graph of a local view. All other data elements are classified as Attributes and form terminal nodes of a local view graph. A Key has a unique value, e.g. Social Security Number, whereas an Attribute does not have a unique value, e.g. age, weight. Duplicated associations are removed from the prepared list of associations and associations such as (A, C) = 1 implied from other associations such as (A, B) = 1 and (B, C) = 1 are identified and listed. If any of the associations in the first list are found to be present in the list of implied associations they are marked as inessential. The other associations in the first list are marked as essential and define the basic structure of the final required integrated data base. The structure may be printed out in graph forms.

Abstract: 1,234,827. Colour television. BELL & HOWELL CO. 10 Oct., 1968 [10 Oct., 1967], No. 48108/68. Heading H4F. Relates to an apparatus for producing electrical signals indicative of a predetermined colour contact of a coloured image comprising a means for producing alternating first and second colour signal components, each of a different spectral range and a further means for obtaining separate colour signal components from said alternating components. The alternating colour components are produced at one output of a colour television camera 50 by means of a filter 20 through which light from the image passes to be converted into electrical signals by means of a camera tube 15, for example a vidicon. In the present embodiment the filter comprises alternating red and substantially clear filter stripes 22, 21 arranged orthogonally to the direction of scanning of tube 15. The resultant alternating red R and luminance Y signal is amplified at 26 and combined to form Y-R at terminal 30 by means of filters 27 and 29 and an envelope detector 28 and Y + R at terminal 33 by means of filter 32. These signals are then combined as shown to produce the separate Y and R signals at terminals 37 and 46 respectively. The blue component signal is produced in the usual manner using a filter 52 and camera tube 15<SP>1</SP> and is combined with the R and Y signals to produce a green component signal at terminal 65. In an alternative embodiment (Fig. 4, not shown) the camera tube 15<SP>1</SP> is also equipped with a filter (70) similar to filter 20 composed, for example, of alternating blue and clear filter strips. The three component colour signals are separated similarly as before. Alternatively, using the camera of Fig. 4, the colour difference signals R-Y and B-Y may be produced (Fig. 5, not shown). In any of the above embodiments the output signals may be recorded on magnetic tape and in the Fig. 4 embodiment the light passing through the two striped filters 20 and (70) may be recorded on separate frames on an intermittently moving monochromatic photographic film (Fig. 6, not shown), playback being effected by projecting the two sets of recorded images on to the two camera tubes 15 and 15<SP>1</SP> (Fig. 7, not shown).

Abstract: 1,208,824. Electrographic process. SAVIN BUSINESS MACHINES CORP. Oct. 10, 1968 [Nov. 9, 1967], No.48111/68. Heading G2H. An electrographic process, particularly suitable for multi-colour reproduction, wherein the sequence of uniform charging, imagewise charge reduction and development is repeated two or more times, is modified by only once uniformly charging the insulative member. A residual charge is left after each imagewise charge reduction, which may be by optical or other means, and the latent image is only partially developed. When charge reduction is by optical means the member is photo-conductive and exposure times may be as short as 0À1 seconds. The image is developed by passing the member between applicator rollers at a speed of 100 ft. /min. Multi-colour images are produced by successive exposure and development using different colours. Suitable developers are a mixture of carbon black, aluminium oxide, safflower oil, modified resin of the glycerylphthalate alkyd type and lead naphthenate stirred hydrocarbon solvent on perchloroethylene, or pthalo-cyanine blue pigment and vinyl acrylic resin dispersed in a hydrocarbon solvent, or pigmented acrylic resin toner, or pigments dispersed in vegetable oils or gums, or metallic powder and fixer resin.

Title: Record Card Feeding Apparatus
IPC: G06K13/103
Filed: 1967-10-24
Abstract: 1,166,888. Feeding record cards. INTERNATIONAL BUSINESS MACHINES CORP. 24 Oct., 1967 [17 Nov., 1966; 12 Dec., 1966], No. 48252/67. Heading B8R. Record card feeding apparatus comprises card engaging means urging cards one at a time from a rest position, the card engaging means being drivable from a cyclically operable driving member through an electromagnetic coupling, the coupling having an armature with its associated electromagnetic coil, a yoke which is brought into contact with the armature once in every cycle of the driving member, and means for selectively energizing the coil. Hopper.-The hopper 10 has a side wall 12 and a rear wall 14, and is canted so that record cards are registered against the walls under gravity. Card engagement members 18 are oscillated to feed the bottom card through a throat 20, defined by an idler roller 24 and a knife 26 adjustably mounted on frame member 28, to pairs of delivery rollers 22. Drive mechanism.-The two card engagement members 13 are fixed to a shaft 60; also fixed to the rotatable shaft 60 is a yoke 44 which comprises two non-magnetic arms 76 joined by a soft iron cross member 48, and normally held stationary by a small permanent magnet 64 fixed to the main frame of the machine. Rotatably mounted on shaft 60 is an armature 46 comprising two arms 72 supporting two non- magnetic extensions 74 and a cam follower roller 56 riding on rotating cam 54 under the action of spring 52. An electromagnet coil 50 is associated with the armature and is generally stationary and concentric with shaft 60. In operation, the cam brings the yoke 44 and the armature 46 together once every cycle; if the coil 50 is energized, e.g. by a signal received from a card reader, the yoke 44 and armature 46 form an electromagnetic coupling; thus when the armature moves away under the action of spring 52 and cam 54, yoke 44 overcomes attraction from magnet 64, and also oscillates causing card engagement members 18 to feed a card (Fig. 1B, not shown). With this arrangement, the coil can be energized at any time in the cycle prior to the selected feeding cycle (Fig. 6, not shown).

In a process of cleaning air filter screen 47 by reverse air flow which screen is used to filter fibre laden air drawn from carding machines 10 through inlets 40 and conduits 41 by fans 51, 52, 53 situated in outlet 46, the reverse flow to clean the screen 47 is effected by reversing the direction of rotation of fans 51, 52 for 2-5 seconds only so that the inward air flow at inlets 40 is not reversed. Expulsion roller 60 is rotated at 7 revs per minute by an electric motor 62. An automatic apparatus for control of the rotation of fans 51, 52, 53 is shown in Fig. 7 in which the timer causes rotation of cam 82 at intervals of 90 minutes so that contact of roller 81 with surface A of the cam allows forward rotation of the fans by allowing contact of switches 70, 71 and 72 with contacts B' and hence completes the electrical circuit to winding B of the fan motors 51', 52', 53'. Contact of roller 81 with surface B breaks the circuit, cotact with surface C allows contact of switch 70, 71, 72 with contacts r' and hence completes the electrical circuit to winding r of fans 51', 52' for reverse rotation of these fans. The filter screen 47 may comprise 3 separate movable sections in parallel, with stiffening bars (Fig. 4, not shown).

Abstract: 1,074,453. Electron multipliers; attenuators and switches. GENERAL ELECTRIC CO. Dec. 18, 1963 [Jan. 31, 1963], No. 50077/63. Headings H1D and H1W. An energy transmitting cell 10 for providing a variable attenuation of microwaves comprises a hollow conical transmission line having an outer conductor 18 and an inner conductor 17, with an evacuated region between windows 20, 21, which permit the passage of microwave energy but are impervious to gas, surrounded by a coil 23 supplied from controllable current source 24. A microwave transmitter 11 is connected by transmission line 13 to the cell 10 and the utilization device 12 for the microwaves is connected through transmission line 14 to the other side of cell 10. The microwaves from transmitter 11 cause a multipactor discharge to take place in the evacuated space in cell 10 between inner conductor 17 and outer conductor 18 in the absence of a magnetic field. When the magnetic field B, parallel to the axis of cell 10 is applied by energizing coil 23, the multipactor discharge is quenched. The multipactor discharge causes attenuation of microwaves passing through cell 10 and thus the cell acts as a variable attenuator. The inner surface of outer conductor 18 and the outer surface of inner conductor 17 are coated with a material such as an alloy of silver and magnesium having a secondary emission ratio greater than unity.
