Abstract: 1408175 Acrylonitrile polymer compositions MITSUBISHI RAYON CO Ltd 10 Nov 1972 [20 Nov 1971 (2) 3 Dec 1971] 51969/72 Heading C3P [Also in Division D2] An acrylic fibrous material, suitable for use in papermaking, consists of 50-80% of acrylonitrile polymer containing at least 85% of acrylonitrile and 20-50% of a C 1  to C 4  alkyl methacrylate polymer containing at least 80% of the ester. The material is prepared by spinning a dope of the polymers, drawing the filaments and then heating them in water or steam in a relaxed state at a temperature of from 75‹ C. to the softening temperature of the acrylic ester polymer. The filaments are cut into staple fibres and can then be formed into paper by conventional methods either alone or combined with other pulp materials. In examples the acrylonitrile polymer is acrylonitrile/vinyl acetate copolymer, acrylonitrile/vinyl pyridine copolymer, acrylonitrile/methyl acrylate copolymer or acrylonitrile/vinyl acetate/allyl alcohol copolymer and the ester polymer is a copolymer of methyl methacrylate with methyl acrylate, ethyl acrylate or 2-hydroxyethyl methacrylate, or polymethyl methacrylate, the polymers being dissolved in dimethylacetamide or dimethyl formamide. These fibres are processed into paper optionally in combination with wood pulp and additives such as rosin size, fillers, aluminium sulphate, polyacrylamide, clay, terra alba and titanium oxide. The resultant sheets may be impregnated with polymers such as methylol melamine, unsaturated polyester resins, phenol-formaldehyde resin or nitrile/ butadiene rubber latex and the treated sheets may be embossed or laminated.

Abstract: 1495060 Stereoscopic photography LAW CHI YIN 22 Dec 1975 [25 Dec 1974] 52443/75 Heading G2A A camera for stereophotography having a lenticular screen adjacent to the photo-sensitive material position has means for moving a diaphragm aperture parallel to the screen, driven by a first motor, and means for moving the screen parallel to the photo-sensitive material position driven by a second motor. As shown, a rectangular objective lens 21 is mounted in a front frame 20, carried by a cylindrical support 31. A rear frame 26, for carrying the lenticular screen, a focusing screen and the photo-sensitive material holder 81, is carried by a holder 34 slidable on another cylindrical support 32. Support 31 slides telescopically inside support 32, so that frames 20 and 26 can be adjusted axially with respect to each other and to an intermediate frame 29, to which they are connected by bellows 27, 28. A variable diaphragm having a central aperture 41 (seen more clearly in Fig. 8 (not shown)) is mounted on a plate 38 in the front frame 20, and can be set to any desired value by a setting dial. The plate 38 is supported between shielding curtains 53, 54 which wind round drums 51, 52. These are rotated simultaneously by a motor-drive chain 63, so that the diaphragm is drawn across an opening 55 which supports the objective 21. The lenticular screen is located in the rear frame 26, and initially a focusing screen is inserted into the holder 81 and brought into close contact with the lenticular screen. The diaphragm is brought into its central position, and the focus adjusted. The focusing screen is then replaced by a film holder containing the film to be exposed, which is also then brought into close contact with the lenticular screen. The screen is mounted so that it can slide laterally, and is driven by a second motor. The two motors are synchronized, and have the same output velocity, but act through respective reduction gear mechanisms, since the diaphragm has to move a larger distance than the screen, e.g. 8 cm as compared with 0À3 mm.

Abstract: 1,160,679. Magnetic data storage matrices. SPERRY RAND CORP. 23 Nov., 1966 [2 Dec., 1965], No. 52496/66. Heading H3B. The data stored in a storage element at the intersection of selected X and Y drive lines in a bit-organized matrix is sensed by detecting the signal induced in the selected Y-drive line. A selection matrix (Fig. 5) for selecting a Y-drive line 62 of a toroidal core storage matrix includes line transformers 42 and bus transformers 44, the appropriate line being selected by energization of a line 48 and a line 50. Current driver 46 is actuated by a read pulse 52 or a write pulse 54 to generate a pulse of a first or second polarity to produce a corresponding pulse on the selected line 62. A similar matrix is provided for energizing a selected X-drive line. The Y-selection matrix only is provided in addition with a sense amplifier discriminator circuit 64 coupled to transformer 68. When a memory element on a selected Y-drive line switches during reading an output signal is passed back through transformers 42, 44 and 68 to circuit 64. The Y-drive current is initiated before the X-drive current during reading so that transients in the Y-selection matrix subside before a memory element is switched. Circuit 64 includes a preamplifierdiscriminator circuit for eliminating the variable D.C. signal level on lines 62. This circuit consists of an R.C. inverter circuit connected to an emitter-follower transistor for clipping the negative peaks of the signal. A further transistor amplifies the negative portions of the resulting signal and the output is differentiated and applied to the input of the sense amplifier, which is strobed at the appropriate time. Several memory planes may be stacked in a three-dimensional array with corresponding X-drive lines of all the planes connected in series and a separate Y-drive matrix for each plane. Alternatively the planes may be stacked in a two-dimensional array.

Abstract: 1371496 Semi-conductor resistors MULLARD Ltd 16 Nov 1971 [9 Dec 1970 27 July 1971] 58478/70 and 53131/71 Heading H1K A semi-conductor resistor comprising a surface region forming a PN junction with the adjacent part of a semi-conductor body has neutral ions implanted in the vicinity of the junction which, together with the associated bombardment damage, reduces the majority carrier mobility at the junction by a factor of at least 3 to give the resistor a more linear characteristic. Suitable neutral ions for use in silicon are those of neon, nitrogen, tin and silicon itself. Bombardment is preferably such as to give a maximum concentration of these ions just below the junction, the bombardment damage, the extent of which can be adjusted by annealing, then being greatest in the depletion region. The resistance region may be formed by diffusion or ion implantation, in which case the two implantations can be performed in either order. A typical device is made by first photoetching a plurality of pairs of holes through silicon oxide on a 3-5 ohm. cm. N-type silicon wafer and diffusing in boron to define contact regions. After etching away the oxide and thermally regrowing a thinner layer contact openings are formed, aluminium deposited overall and a strip of it between each pair of contact regions removed. The aluminium acts as a mask during successive bombardments with neon and boron ions, and after annealing at 500‹ C. is removed patternwise to form contacts. Results are given for different surface orientations, ion dosages and a reversed bombardment sequence. Where the resistors are to form part of an integrated circuit their ends may merge, e.g. into regions of adjacent bipolar or field effects transistors thus rendering the aluminium contacts superfluous.

Title: Methods and apparatus for plugging well bores with hardenable fluid substances
IPC: E21B33/134
Filed: 1970-10-10
Abstract: 1331797 Wells SCHLUMBERGER INLAND SERVICES Inc 10 Nov 1970 [12 Nov 1969 (2)] 53376/70 Heading E1F Well plug consists of a bag which is inflated with a fluent but hardenable material, and after inflation axial pressure is applied to the bag along its axis to increase the pressure within the bag and hence the frictional force holding the bag in the well. The bag 18 is a sleeve secured to upper and lower collars 71, 72. The hardenable material 23, covered by a piston 32, is stored in the upper part of the tool (Figure 2A), and the inflation process is initiated by releasing a spring loaded piston 35 which strikes the piston 32. The impact causes a valve 60 (top of Figure 2B) to be depressed (shearing pin 63) so that the material can flow along annular passages 69 and radial passages 81 to inflate the bag 18. The upper collar 71 is held by latches 78 so that as the bag inflates, the lower collar 72 is raised up the body 70 of the plug. When the bag is inflated and is consequently retained in the well by friction, the body of the plug is pulled upwards, the latches 78 disengaging from the recess 79 and engaging the recess 85. Also a latching mechanism comprising a sleeve 109 and balls 106 is raised with the body until projections 114 on the sleeve engage the lower collar 72. This releases the latching mechanism allowing a spring 104 to extend and apply an axial force to the bag, acting through an annular member 103 and the lower collar 72. The plug is now in the Figure 5 position. When the upper collar 71 has been raised relative to the body 19, the hardenable material continues to be expelled by the pistons 32 and 35 (Figure 2A), but the radial openings 81 now discharge it into the space above the bag. This continues until the piston 32 engages and depresses a member 55 and a support ring 54, allowing latches 52 to disengage so that the upper part 10 of the tool may be withdrawn. A by-pass is formed by passages 66, 64 (Figure 2A), 83 (Figures 2B and 2C) and 86 (Figure 2C), which prevent excess differential pressure developing across the plug. The bypass is closed after a predetermined time sufficient to allow the hardenable material to set by a valve closure 87 (Figure 2C) which is raised by a spring 81 to block the passages 86 when a connection 101 (e.g. a cord wrapped around a shaft) is released by an escapement 96.
