Title: Alphanumeric facsimile information printer
IPC: H04N1/04
Filed: 1970-09-11
Abstract: 1329263 Copying by scanning XEROX CORP 11 Sept 1970 [18 Sept 1969] 43592/70 Heading H4F A data printer which may be used for both alphanumeric and fascimile reproductions comprises a plurality of scanning electrode units 10 each having ten electrode elements which are selectively energized by signals from a coding matrix 30 which receives its input over a transmission line or from a magnetic tape or disc file 34 or a T.V. camera 36 or a keyboard 38, the input to the coding matrix 30 containing an input as to whether alphanumeric or facsimile information is to be printed. For alphanumeric printing seven adjacent electrode elements are used to scan the reproduction, the three non-  used electrode elements automatically providing the spacing between adjacent lines. After one scan by the unit 10 the motor 42 advances the reproduction via rollers 48, 50, and the coding matrix 30 receives a further alphanumeric/ fascimile input. For fascimile printing each electrode element is used in turn, the reproduction remaining stationary for ten scans one using each electrode element, after which it is again moved on by motor 42 and coding matrix 30 receives another alphanumeric/facsimile input. A cathode-ray tube 41 may be used for visual inspection of the information to be printed, and the scanning electrode unit 10 may be coupled to the coding matrix 30 by an arrangement of plates or blades on a stationary electrode structure which has parallel linear surfaces which contact the unit 10. The paper on which the reproduction is printed may be electrolytic; electrographic or electroresistive. A timing track on the electrode unit 10 may be referenced to a commutator on the motor 42 to reduce jitter problems with facsimile printing.

Title: Electrical storage of information
IPC: G11C13/04
Filed: 1965-10-19
Abstract: 1,117,335. Photoconductive data stores. RANK XEROX Ltd. 19 Oct., 1965 [23 Oct., 1964], No.44232/65. Heading G4C. A unitary electrical signal storage element 10 comprises, as shown in Fig. 2, an electrical conductive layer 15, an electrical blocking layer 14, a light absorbing homogeneous photoconductive insulating layer 13 able to trap at least one polarity of charge carrier, an electrical blocking layer 12 and an electrical conductive layer 11, either the layers 11 and 12 or the layers 14 and 15 or both being transparent. The signal is stored by trapping electrical charges within the bulk of the photoconductive insulating material to form a space charge therein (by flashing lamp 16 with power supply 19 connected) and is retrieved by subsequently neutralizing the space charge (by flashing lamp 16 with power supply 19 disconnected) to create an electrical signal in an electrical circuit 23, 22 connected to the photoconductive insulator. An oscilloscope 21 is provided to observe the signal. A modified circuit is illustrated in Fig. 1 (not shown). Fig. 4 (not shown) illustrates the arrangement of a matrix store employing an element 10 similar to that described above. The lamp 16 is replaced by a cathode ray tube (40) which is focused on to the element (10) by a lens (41) so as to expose only selected areas of said element. As read-out is largely destructive, the read operation is arranged to include a regenerative step. Further, as the stored data remains for only about 10 minutes, a timing counter (65) is included whereby the entire contents of the store are regenerated cyclically. Alternatively, two such stores may be provided (Fig. 5, not shown), the arrangement being such that data read from one store is also transferred to the other and vice versa, the address, read and write inputs of both devices being connected in parallel. A group of stores such as in Figs. 4 and 5 may be addressed in parallel to provide a wordorientated storage system, each store being provided with its own cathode ray tube or several stores sharing a single tube by means of beam splitting arrangements. Other selective illumination arrangements are referred to including cross-grid electro luminescence or mechanical devices (e.g. using rotating drums or discs). The blocking layers may comprise, for example, zinc sulphide or polyvinyl chloride. Alternatively the blocking layers may be formed by the interface between suitable conductors (e.g. oxidized aluminium or tin oxide) and the photoconductive material. The conductive layers may comprise gold or other metals, or copper iodide. The photoconductive material may comprise selenium preferably with traces of chlorine present. Electron beams may replace visible light. The store may be used (without regeneration) in a digital printer buffer store.

Title: Colour pickup tubes
IPC: H01J31/46
Filed: 1974-10-14
Abstract: 1456772 Image pick-up tubes HITACHI Ltd 14 Oct 1974 [5 Nov 1973] 44494/74 Heading HID In a vidicon pick-up tube for a one- or twotube colour TV camera system a glass substrate 1 sealed to one end of the glass pick-up tube carries a transparent conductive layer and photoconductive layer 5 as in the prior art but separated from interference strip filters 2, 3 by a dished transparent layer 9. The layer 9 inhibits impairment of the photoconductive layer by the interference filters during heating in manufacture: a thin layer 9 tends to peel off (as 8 in prior art) but this is prevented by thickening of the edges, tolerable optically with the smaller focusing angle near the periphery of the screen to provide acceptably sharp shadow images of the filter strips on the layer 5. One face of layer 9 is preferably flat, the curvature of the other depending on the details of the camera lens used with the tube. A shaped convex grinding tool (Fig. 4, not shown) may be used to form the profile of layer 9.

Filed: 1970-09-22
Abstract: 1291310 Apparatus for lidding tins BAKER PERKINS Ltd 10 Sept 1971 [22 Sept 1970] 45042/70 Heading B8C In an apparatus for lidding tins, for example bakery tins each charged with dough and which are bound for a baking oven, or prover, a rotor 1, rotatable in steps of 90 degrees by a motor 17 and chain drive 15 and carrying four equiangularly spaced magnets 4 associated with respective retaining lugs 6, picks up lids from a conveyer 9 as they are successively released by a stop member 10, which works in synchronism with the rotor 1. The latter transfers the lids to engage the leading edges of corresponding tins which are released, one at a time, from a tin conveyer 11 by a stop 12 which also works in timed sequence with the rotary member 1. The lids are stripped from the magnets by the endless belts 8 or by a stationary plate 13. If desired, the tin stop 12 may be eliminated, in which case the conveyer 11 is provided with flights which correctly space the tins. A photo-electric cell may sense the tins and thus avoid discharge of a lid on to an empty space on the conveyer. In a modification, the rotor is freely mounted and is intermittently driven by frictional engagement during the lidding operation for example with a drive belt, a suitable braking device also being provided. In another arrangement a clutch may be used to intermittently drive the rotor 1. After the lidding operation the tins may be discharged to a further, variable speed, conveyer. The means for holding the lids on to the rotor could comprise electromagnets, suction pads, side clamps, a pair of plates, or discs, rotatably mounted about different axes. The rotor comprises a pair of spaced pulleys mounted upon a shaft 2 which is carried by a pivotally adjustable frame 3.

[Also in Division G1] To determine the degree of clogging of a filter for fluids the filter housing is made movable against a spring by the pressure difference built up across it, and the extent of movement is measured electrically. As shown (Fig. 1), a filter assembly 28, located in a housing 10 between a fluid inlet 16 and outlet 14, comprises two annular end members 30, 42 bolted together to hold a filter element 52 and biased by a spring 34 against one side. Member 42 carries a resilient contact 64 which cooperates with a resistance winding mounted on the housing 10 by a bolt 66. Clogging of the filter element causes a pressure difference to develop moving the assembly 28 axially against the spring and also moving contact 64 along the resistor, enabling the movement to be measured. Excessive clogging produces sufficient movement of assembly 28 to allow the fluid to by pass the filter element 52 and flow through slots 58. Another embodiment is described with reference to Fig. 4 (not shown).
