Title: Photoelec tric conveting member for colour pickup tubes and method of manufacturing the same
IPC: H04N9/07
Filed: 1974-09-10
Abstract: 1450504 Image pick-up tube HITACHI Ltd 10 Sept 1974 [5 Oct 1973] 39354/74 Heading HID In the manufacture of the photo-electric converter plate of a colour pick-up tube with a known stripe filter, 2 (e.g. diohroic interference filter) on substrate 1, defects due to consequent irregularities in the overlying transparent conductive and photo-conductive layers 5, 6 are avoided by applying a transparent inorganic layer on the filter before addition of layers 5, 6, the applied layer being double or inhomogeneous with the first part nearest the filter deposited under inert gas and O 2 , and the later parts being deposited with lower O 2  partial pressure. For example, layers 3 and 4 may be of silica, layer 3 being 2 Ám thick, i.e. thinner than the stripes 2, sputtered under 10<SP>-3</SP> Torr of inert gas, e.g. Ar, containing O 2  at 10<SP>-5</SP> Torr forming near stoichiometric SiO 2  which inhibits discoloration of the filter, and layer 4 being 8 Ám thick and sputtered with O 2  reduced to 10<SP>-7</SP> Torr forming SiO n  (n= 1.6-1.8). On layer 4, optionally ground optically flat, layers 5 and 6 are deposited. The atmosphere in the second stage may be oxygen free. In place of double layer 3, 4, a single layer may be deposited with gradually falling oxygen concentration. Silica may be replaced for example by another oxide or oxide glass.

Abstract: 858,722. Photo-electric devices. UNITED KINGDOM ATOMIC ENERGY AUTHORITY, and MACADIE, H.S. Feb. 13, 1959 [Dec. 20, 1957], No. 39740/57. Class 40(3). A measuring instrument of the kind having a pivoted pointer arranged to sweep over a graduated scale comprises a light-guide which transmits light from a source to a photo-sensitive detector, and a vane arranged to move with the pointer which, in a certain position of the pointer interrupts the passage of light to the detector. As shown Fig. 1, light from a source (not shown), behind a window 26 in the scale-plate 22 of a moving coil meter, travels down two light-guides 9 made of methyl methacrylate rod to illuminate photo-transistors 16, the collector currents from which energize a relay. When the pointer is at zero or full-scale deflection, a vane 8, which is fastened to an arm 7 carried by the moving coil 4, 180 degrees away from the pointer 5, is interposed between one of the photo-transistors and the lower end of its respective light-guide, thus deenergizing the relay. In the embodiment shown in Figs. 4 and 6, three photo-transistors 16 are located on radius arms 41, adjustably pivoted on a sleeve 42 at the back of the meter, light from a source 12<SP>1</SP> is reflected by a polished conical brass 36 on to a methyl methacrylate annulus 34, the outer, illuminated edge of which is adjacent the photo-transistors. At predetermined positions of the pointer, which are indicated by the locations in a slot 57 in the front wall of the meter of fingers 55 connected to adjustable arms 41, one of vanes 8<SP>1</SP>, 8<SP>11</SP>, mounted on arms 7<SP>1</SP>, 7<SP>11</SP> normal to the pointer 5, interrupts the light to one of the phototransistors.

Apparatus for folding down and securing one or more closure flaps of a hinged lid carton comprises means for feeding each carton to supports which suspend it above a plunger, means to apply adhesive to the flaps and a die through which the plunger forces the carton to fold down the flaps and seal them in position. Filled cartons C1 are advanced (from left to right, Fig. 1) against a stop 20 by a conveyer 18 and pushers 19, rollers 21 having folded down the lid which is retained closed by bars 23. Dogs 27 of a further conveyer 25, 26 feed the cartons towards the plunger 28.

Abstract: 1395383 Drying articles CARRIER DRYSYS Ltd 9 Aug 1973 [31 Aug 1972] 40482/72 Heading F4G [Also in Divisions B2 and C7] A vehicle body or similar article is dipped electrophoretically, or spray painted, phosphated, dried or otherwise treated when mounted with its centre of gravity located substantially on, and its longitudinal axis at an acute angle to, an axis of rotation about which the body is rotated or oscillated when mounted in a cradle (Fig. 14) comprising two co-axial rings 13, 14. As shown the rings 13, 14 are releasably interconnected by a top bar 52 and pivoted at the bottom, for lowering to the horizontal for loading of the body, at 48, 49 to vehicle supports 50, 51 on which a body skid 59 is secured. One ring at least has a toothed ring 24 or segment for rotating or oscillating the body. As shown in Fig. 12 the body is successively dipped in alkali, rinsing and phosphating solution tanks by operation of a winch 41 which lowers it vertically on to rollers 43 in each tank and rotating the cradle by a chain 44 or by a pivoted endless track arrangement 44 (Fig. 11, not shown). Alternatively the cradle is rolled (Fig. 10) by a roller 36 on a depending arm 35 along two tracks 34 at the bottom of the tank. Preferably the cradle is rolled by a chain 13 (Fig. 8) engaging it at the top along a pair of tracks 18/19 down and up the sloping side walls of successive tanks, each tank having one or two gaps in the tracks where the cradle falls on to rollers 26, 27 which rotate the cradle. After rotation the leading roller 26 is lifted to 26a when the cradle re-engages the chain 23 and proceeds to the next treatment stage.

Abstract: 878,178. Making corrugated tubes; stamping; altering physical properties. OLIN MATHIESON CHEMICAL CORPORATION. Dec. 1, 1959, No. 40852/59. Classes 83 (2) and 83 (4). A method of working metals with explosives is characterized by transmitting the force of an explosive charge to a metal through a gel. In an embodiment a metal tube 27 is filled with a gelatinous solution and permitted to stand until its phase changes to a gel 5. The gelfilled tube is placed on a split die 11 mounted within a die holder 13. An explosive charge 22 and a detonator 23 is placed in a bore 21 in the die holder and the die holder is placed within clamping means (not shown). When the charge is ignited the explosive force is transmitted through the gel 5 to expand the tube into the die cavities 12 and 17. Discs 16 and 19 on the die holder act as bleeding means to relieve the contained pressure within the assembly. A reversible gel may be used so that it may be recovered and re-used many times. In another embodiment the explosive is suspended in the gel as shown in Fig. 2. Resilient cup-shaped obturating seals 34 and 35 (Fig. 7) are preferably placed in the ends of the tube to prevent loss of gel. In a further embodiment a metal sheet 51 is placed against a cupping die 49 mounted on a holder 41 containing a chamber 42, and a breech mechanism 47 for receiving a cartridge 48. A gelatinous solution is poured into the chamber 42 and allowed to gel. Alternatively, the gel may be preformed to the shape of the chamber and handled as a solid. In a modification, the explosive charge is embedded in the gel. A tube having complex curvatures may be formed with bulged portions by filling the tube with a gel as hitherto, and placing the tube in a die 66 (Fig. 11) having cavities 61 and a breech mechanism 64. In another embodiment the tube is formed against a mandrel 68 or 74 (Figs. 12 and 13) having a screw-thread or ribbed configuration. The mandrel is formed of a material having a lower melting point than the tube, e.g. woods metal or aluminium, to enable the mandrel to be melted from within the tube after the forming operation. A door knob is formed by the method of the invention using a closed ended tube 79 filled with gel and placed between dies 83 (Fig. 14). Similarly, a tumbler-shaped container is formed from a gel-filled tube 79, the open end of which contains a resilient obturating sealing member 82 (Fig. 16). In an example, the explosive powder is prepared by impregnating 80% by weight of nitrocellulose with 20% by weight of nitroglycerine. The gelatinous solution is prepared by mixing 20% by weight of gelatin derived from animal protein in water with agitation. Sodium benzoate and an anti-foaming agent are added to the colloidal solution.
