A vidicon target has a thin insulating layer on one or both sides of the photo-conductive layer to increase the height of the potential barrier to electrons or holes entering the photoconductive layer but providing no barrier to carriers leaving the layer and so to reduce the dark current level. The photo-conductive material may be lead oxide, cadmium sulphide or antimony triselenide; the insulating material on the scanned side of the photo-conductive layer may be cerous fluoride or lithium borate; the insulating material adjacent the signal plate, e.g. of tin oxide, may be cryolite or magnesium fluoride. Suitable dimensions for the layers are given. If an insulting layer is not provided on one side of the photo-conductive layer, the potential barrier may be raised on that side by doping the photo-conductive material, e.g. lead oxide, by regulating the amount of oxygen graded through the layer.
Patent GB-530155-A (GB)
Abstract: 530,155. Lighting gas burners. JUNKERS & CO. GES. June 19, 1939, No. 17837. Convention date, Aug. 6, 1938. Addition to 483,901. [Classes 75 (i) and 75 (iii)] [Also in Group XXIX] In the flash-over ignition device for gas burners in which a flash-over tube is moved into a gas-collecting position when the burner is to be ignited and is returned to a neutral position after the ignition, an electric ignition circuit is closed when the flash-over tube is in the collecting position. In the apparatus shown a gas supply pipe 2 is connected by a cock 3 to a chamber 4 from which leads a pipe 5 to the main burner 6. A valve 7 controlling the admission of gas to the pipe 5 is operable by the pressure difference on two diaphragms 9, 10 in a chamber 11, the space above the diaphragm 10 being connected to the atmosphere by a vent 13. The space below the diaphragm is connected to the atmosphere when the cock is closed by a passage 14 in the chamber wall and a passage 15 in the cock. The cock is also formed with two passages 18, 19 connected by a valve 32 operable against spring pressure by the cock handle 16. Two passages 20, 21 in the casing of the cock 3 are connected by pipes 22, 23 to a casing 24 closed at the top by a flexible diaphragm 25 formed with a pilot jet nozzle 26. The pipe 23 is fitted with an electromagnetically operated valve 28 controlled by a roomthermostat 29 and is closed inside the casing 24 by a valve 27 connected to the diaphragm 25. A byepass 31 is provided adjacent the valve 28. When the handle 16 is depressed and turned slightly the passages 18, 19 are brought into communication with the passages 20, 21 and an inclined rod 40 on the handle engages an arm 41 on the flash-over tube 35 and moves the collector tube 36 above the nozzle 26. The gas issuing from the nozzle 26 becomes ignited by a filament 37 at the top of the tube 35, the filament being raised to incandescence on the depression of the handle 16 by the separation of contacts 38, 39 by which it is normally short circuited. The heat of the pilot jet causes the diaphragm 25 to raise the valve 27. The handle 16 is then raised thereby closing the valve 32 and allowing a spring to restore the tube 35 to its initial position. When the cock is moved to the fully open position gas can pass through an opening 42 in the cock to the chamber 4. In the open position a passage 43 in the cock connects a small opening 45 in the passage 20 to the chamber 11 so that gas can pass from the chamber 24 to cause the valve 7 to be opened to supply gas to the burner 6 for ignition by the pilot jet 26. When the desired room-temperature is reached the switch 29 opens thereby closing the valve 28 and diminishing the gas pressure in the casing 24 and chamber 11. The valve 7 consequently closes and the burner 6 is extinguished, the pilot jet 26 remaining alight. In a modification depression of the handle 16 opens the circuit of the valve 28 and closes the circuit to the filament 37. In a further modification the filament circuit is independent of the circuit of the thermostat 29 and valve 28 so that ignition of the pilot jet can always be effected.

Title: Improvements in or relating to winding apparatus for packaging yarn
IPC: B65H54/34
Filed: 1964-12-31
Abstract: Transfer tails are wound on the package supports 43, 44 Fig. 2, (not shown), by first guiding the yarns over auxiliary guides 8 that are normally in a first position near yarn snagging grooves 45, 46 in the package supports.  When the yarns have been caused to snag in said grooves, by means of a hand tool 28, the auxiliary guides 8 can, in response to a signal, be caused to pivot to a second position where they transfer the yarn to self-threading traverse guides 62, 63 whereby to wind a transfer tail between each groove and the adjacent package area.  As shown the running yarns are initially taken up by a suction device 41 but can be suitably spaced from each other by the guides 34, 35 on the hand tool.  The hand tool is then moved towards the yarn snagging grooves in a manner causing the yarns to snag therein and break the yarn length between the grooves and the suction device By pressing a button 38 on the hand tool 2 a transmitter 27 sends a signal to a receiver 26 in a housing 3 carrying the auxiliary guides 8.  The received signal is used to cause the auxiliary guides 8 to move from the first to the second position.  The housing 3 is pivotable so that the guides 8 can be used in association with yarn winding means on the other side of the machine.  The housing 3 is removable so that it can be used with any of the other and similar winding machines.  In a modified construction Fig. 4 (not shown) the guides 34, 35 are bent wire formation and the hand tool is so shaped that it can be inserted into support and guide means to cause the guides 34, 35 to be accurately aligned with the snagging grooves 45, 46.  In this construction the transmitter and receiver are absent and the housing 3 has manually operable means for causing the auxiliary guides to pivot.  In a further modified construction the transmitter and receiver are replaced by a plug-in connection.

In a continuous casting machine the cast strand 4 after passing through secondary cooling means 6 and withdrawal rolls 7 and after having its starter bar 5 separated, is deflected round a pivotally mounted curvilinear guide 8 and is initially straightened by a pressure roller 12 acting on the convex side of the strand. In operation the guide 8 is initially held in its upper position so that the starter bar 5 passes vertically between rests 9 and 10. When the top end of the starter bar 5 passes rest 9 the guide 8 is pivoted about pivot 13 to its lower position so that rest 9 bends the free end of the strand 4 and rest 10 pushes the top of the starter bar 5 sideways. The bent strand 4 passes along the guide 8 until its free end reaches the exit end of a frame 16 whereupon the guide 8 is raised again to its upper position to force the strand against support rollers 17, 18 and a driven roller 19 to initially straighten it. The starter bar 5 is held in a pivotable table 20 that includes a driven roller 22 so that the starter bar can be rotated to a horizontal position and passed out of the machine through the guide 8, over the rollers 17, 18, 19. The casting machine may be casting multiple strands and the starter bar may be articulated. The rollers 17, 18 and 19 are adjustable in height to accommodate strands of various thickness. The strand is cut into lengths on a roll table 29.

Abstract: 1283310 Supplying sliver to spinning machines; sliver cans SCHUBERT & SALZER MASCHINENFABRIK AG 17 Nov 1970 [24 Dec 1969] 54604/70 Heading D1F In a method of supplying sliver F to a spinning machine 1 having spinning stations 4, the sliver is filled into cans 3 at a preceding fibre treating machine, is moved in these cans 3 to the spinning machine 1, is filled into supply cans 5 arranged permanently adjacent the spinning machines and is passed to the spinning stations 4 from the supply cans 5. The sliver F is fed from the can 3 to a refilling device 2 which is preferably a coiler to deposit the sliver in the supply cans 5. In a preferred embodiment, the supply cans 5 are arranged on a series of four tracks K 1 , K 2 , K 3  K 4 , the tracks K 1 , K 4  being positioned for the feed of sliver to the spinning stations 4 in a double-sided spinning machine. The supply cans 5 are aranged such that three tracks are fully occupied. During a filling operation, the tracks K 1  and K 4  are stationary and the cans 5 are moved stepwise from track K 3  to track K 2  via the filling device 2. The cans are prevented from transfer to tracks K 1  and K 4  by means of pivoted flaps 71 and 72. When the cans in track K 1  are emptied by the spinning stations, the tracks K 1 , K 2  are circulated to transfer filled cans 5 to the track K 1  and empty cans to the track K 2 , the pivoted flaps 71 having been moved to position 71' to prevent misdirection of cans. The motor driving the tracks K 2 , K 3  is then reversed and the flaps pivoted back to their original positions. The empty cans 5 are then moved stepwise from track K 2  to track K 3  via the filling device 2, the flaps are again pivoted and transfer of cans from track K 3  to track K 4  and vice versa is effected. The motor is again reversed and the cycle is repeated. In this embodiment the tracks K 1 , K 2 , K 3  and K 4  take the form of endless chains 61, 62 and 63 with can engaging dogs 67 and restraining rails 75 and 76. In a further embodiment, all four can tracks are fully occupied by supply cans, and the inner tracks are connected together at both ends. All the cans on the inner tracks are circulated via the filling device so that all cans on the inner tracks are filled. The filled cans are then transferred to the spinning stations tracks on both side of the spinning frame simultaneously. In an alternative embodiment, the cans are not circulated but are exchanged by lateral transfer in rows, which tranfer can be alternately to the two sides of a spinning frame or simultaneously. The lateral transfer is effected by means of rails extending the length of the rows and mounted on arms depending from the machine frame and reciprocable in a direction transverse -to the rows of spinning stations.

Abstract: 1,132,710. Ornamenting. GUSTAFS LIST A.B. 31 Dec., 1965, No. 55490/65. Headings B6G and B6J. [Also in Division B5] A method for ornamenting a wooden object comprises treating the wood with a press means, the surface of the press means facing the wood being furnished with a layer of a soft elastomer such as rubber, the pressure of the press means being set so that only the soft parts of the wood are depressed thereby bringing forth the natural graining of the wood. The wood may be preheated prior to pressing, and the press means may be heated. The surface of the wood may be irregular. Before or during the press treatment, the wood may be brought into contact with a gold foil coated with a layer of adhesive material. The depressions in the wood may be rendered permanent by coating the wood with a prepolymerized, quick hardening plastics before or after the treatment with the press means. In Fig. 1, a support roller 4 is rotatably mounted on frame 1, and is driven by motor 2. Press roller 5 furnished with an elastic material 6 on its surface is rotatably mounted on frame 1 above support roller 4 by bearing tube 21 lying within bearing sleeve 7. Press roller 5 is horizontally adjustable in sleeve 7 and sleeve 7 is movably arranged on positioning plate 9 by means of adjustment arm 11 and lever arm 22 which are located on opposite sides of positioning plate .9. Plate 9 is constructed with two locking devices 10 comprising each a bolt and reversible washer 23 for setting the angle of roller 5. A spring device 12 in the form of a spring load screw is mounted on the lower part of adjustment arm 11, and acts against positioning plate 9 thereby providing the adjustment means for microsetting of the pressure of the press means. Press roller 5 is heated by heat lamp 20. After setting the pressure of the press means to bring forth the desired degree of graining, material used for ornamenting the wood is drawn from adjustable holder 19 and contacted with press roller 5 and inserted in between rollers 4 and 5 in contact with the wooden object, say a picture moulding.
