Title: Shutter for CCD imager
Inventor: PITTOCK ROGER JOHN
IPC: H04N5/235
Filed: 2009-03-17
Abstract: A CCD sensor 1 has a shutter 4 to prevent frame shift smear during transfer of an image from the image region 2 to a store region 3. The shutter has 2 blades 5, 6 which divide the integration period into 2 parts. In the first, longer, part the sensor signal is clipped by capping the charge, but this capping is removed in the second, shorter, part. The result is that the CCD sensor has an extended dynamic range because the second part has a different sensitivity to the first part. The two shutter blades avoid an asymmetry in the uncovering and covering of the image region. Separate blades may be used to vary the size of the gap 7 and integration times.

Title: Producing damage in semiconductor bodies
IPC: C30B33/00
Filed: 1976-03-13
Abstract: 1483888 Processing semiconductors INTERNATIONAL BUSINESS MACHINES CORP 13 March 1976 10135/76 Heading H1K [Also in Division B3] Damage is produced in a surface of a semiconductor wafer 26 by placing balls 32, e.g. of tungsten, on the surface and acoustically vibrating the wafer. The resulting controlled damage comprises shallow grooves, formed by a fine strongly directional abrasion, and Hertzian fracture cones, and may be employed as a research tool or as a stress relief agent when followed by a high temperature process, such as oxidation, diffusion, epitoxy or ion implantation, in semconductor device manufacture. MOS capacitors are particularly referred to.  In one application of the invention a buried silicon nitride layer is formed in a silicon body by the following steps: (i) a sub-surface ion implantation of nitrogen is carried out into the body; (ii) the non-implanted surface is damaged by the inventive method; (iii) the body is annealed to convert the inplanted layer to silicon nitride; and (iv) an epitaxial silicon layer is grown on the inplanted surface. Apparatus for carrying out the invention comprises a loudspeaker at the end of a PVC tube across which the semiconductor wafer 27 carrying the balls 32 is secured. Preferably the loudspeaker is turned to the resonant frequency of the wafer. Several wafers may be received in the same tube, optionally in pairs so that the balls vibrate between the wafers of a pair. Two loudspeakers, operating 180 degrees out of phase, may be located at opposite ends of the tube.

Title: Method and apparatus for surfacing glass
Inventor: WALTERS EMMETT LEO
IPC: B24B7/24
Filed: 1962-03-17
Abstract: 993,366. Surfacing glass sheets. LIBBY-OWENS-FORD GLASS CO. March 17, 1962, No. 10310/62. Heading B3D. A method of surfacing a glass sheet 10, Fig. 3, consists in applying surfacing pressure to a plurality of areas of the sheet extending transversely thereof by a surfacing runner 17 having a plurality of working faces 18 arranged side-by-side, and feeding a surfacing medium to each face while disengaging any individual face from the sheet during such feeding so that the medium may spread over such face into contact with the sheet immediately adjacent the face. Such an arrangement may be employed for polishing only the upper face of the sheet or for simultaneously treating both the upper and lower faces of the sheet as shown in Fig. 1 wherein an opposed pair of runners 17, 29 acts on a sheet supported by driving rollers. Each runner is given a circular motion during the surfacing of the moving sheet by cranks 19, 31 driven respectively by motors 24 and 35 through worm gearing 22 and 33, and shafts 23, 21 and 34, 32, the shafts 21, 32 being vertically adjustable by motors 28 and 36 through casings 25, 40 and gearing 27, 38 whereby the runners 17, 29 may be moved into engagement with or away from the glass sheet. Hydraulic actuators 41, 42 maintain the required overall surfacing pressure after the runners have been brought into contact with the sheet. The control means for disengaging the contact faces 56 of the individual surfacing elements 18 and for supplying the surfacing medium to a longitudinal groove 63 in the felt, plastic or rubber face of each element are shown in Fig. 3. A pump 65 periodically lowers the pressure within an associated diaphragm 59 attached to each element so that the contact with the glass surface is broken, a further pump 79 simultaneously supplying the surfacing medium from a source 81 to the groove 63; timers 69 and 82 connected to a common electrical supply 72, 73 control the periodic and simultaneous operation of the pumps 65 and 79. Since all the diaphragm and surfacing medium control units 64, 77 of the individual elements 18 are connected to a common electrical supply they may be synchronized or the timers may be adjusted relatively to provide any desired pressure pattern across the sheet under each runner 17. In a modified form of runner the diaphragms 59 are replaced by tension springs which oppose a pressure medium supplied by the pumps 65.

Title: Apparatus for Securing End Caps to Tubes
IPC: B23K35/40
Filed: 1967-03-06
Abstract: 1,169,811. End capping tubes. VIDA-WELD PTY. Ltd. 6 March, 1967 [28 March, 1966], No. 10470/67. Heading B3V. Apparatus for securing end caps 33, Fig. 7, on tubes 43 comprises an anvil-die 15 with a passage for receiving a tube 43 and admitting a cap 33 for only a limited distance along the passage, a press-die 26 for engaging the cap when loosely applied on the tube extending through the passage, and means to move the die 26 to force the cap part way into the passage, thus contracting it on to the tube. The end of the passage is flared to effect this operation. As applied to end-capping welding electrodes, double-length electrodes are supplied to the apparatus, which has a die-assembly at each end for capping both ends of the electrodes in successive operations, the electrodes then being severed into single lengths by shear blades 40, 41, Fig. 1, which also close the severed ends. The anvil-dies 15 are divided on the passageaxis, and the die-sections 15A, 15B are separated by toggle links 21 and pneumatic cylinders 20, to permit lateral insertion of the lowermost tube 43A delivered by conveyer chains 45. A pawl-and-ratchet mechanism driven by a pneumatic cylinder. Fig. 6 (not shown), operates the chains in steps, so that in preceding strokes of the press dies 26 abutments 34 on the dies push end caps from a shoot 54 at each end of the apparatus on to the tube which is located in higher passages of the anvil dies. The next operation of the conveyer chains allows the tube with the caps fitted loosely to fall on to support rods 44 aligning it with the lower passage axis of the dies. The rods are withdrawn by pneumatic cylinders 62 so that when the anvil dies again open, after the capping and shearing operations, the severed tubes will fall through a slot 42 in the apparatus. The press dies 26 are operated, through toggle links 28, by pneumatic cylinders 27 and have bores 31 to receive stems 32 on the end caps 33. A pneumatic circuit is described, Fig. 8 (not shown), which may control the apparatus automatically. In various alternative forms, the support rods may be fixed and the tubes positioned manually, or the dies may be operated by solenoids, or by cams, driven by a one-revolution clutch.

Filed: 1952-04-25
Abstract: Hydrocarbon fractions boiling within the motor fuel range are hydroformed in the presence of a catalyst prepared by mixing a compound of platinum or palladium with alumina hydrosol, drying the product, and activating with hydrogen; a halogen compound, e.g. hydrogen fluoride, and also silica, chromia, or zirconia may be included in the catalyst (see Group III).  Hydroforming is carried out at 600-1000 DEG  F. at pressures of up to 1000 lb. per square inch (preferably 50-250 lb. per square inch), at feed rates of 0.25-4 V/V/hour, and in the presence of 2000-12,000 cubic feet of hydrogen-rich gas per barrel of liquid hydrocarbon.ALSO:Platinum - alumina and palladium - alumina catalysts for hydrocarbon conversion are prepared by mixing a compound of platinum or palladium with alumina hydrosol, drying the product, and activating with hydrogen. The alumina hydrosol, which preferably contains 1-6 per cent. of alumina, may be prepared by treating aluminium metal with a dilute acid, e.g. acetic acid, in the presence of mercury or a mercury compound or by hydrolysis of an aluminium alkoxide, preferably derived from a water-insoluble alcohol; in the latter method the alkoxide dissolved in alcohol or a hydrocarbon is treated with glacial acetic acid as a peptizing agent, and then mixed with water at 150-200 DEG F.  To prepare the catalyst, the sol is mixed with a solution of chloroplatinic acid, ammonium choroplatinate, or palladium chloride, and the mixture may be treated with hydrogen sulphide; alternatively the platinum or palladium solution may be treated with hydrogen sulphide before mixing with the sol.  Halogen compounds, e.g. hydrogen fluoride, hydrochloric acid, ammonium fluoride, or aluminium chloride, may be added to the platinum or palladium solution or to the platinum- or palladium-containing sol. or the gel product may be treated with gaseous or aqueous halogen acid.  Drying is carried out at 200 DEG -400 DEG F. and activation with hydrogen at 500 DEG -1000 DEG F. The final catalyst preferably contains (by weight) 0.2-1 per cent. platinum or 0.5-3 per cent. palladium and 0.1-4 per cent. halogen.  From 1-10 per cent. of silica, chromia, or zirconia may be included to improve the stability.  One of the examples mentions the addition of formaldehyde as a preservative.  The catalysts are useful in hydroforming hydrocarbons (see Group IV (b)).
