Abstract: 1296103 Electric cell UNION CARBIDE CORP 20 Feb 1970 [20 Feb 1969] 8304/70 Heading H4B In an electric-cell, particularly flat thin cells which can be stacked in series to form a battery, the metal anode is physically separated from a cathode-depolarizer mix and adhesively secured directly or indirectly to one surface thereof by a polymeric adhesive thus providing an ionically conductive path between the anode and the mix, and the cathode collector is adhesively secured to the opposite surface of the mix by an electronically conductive polymeric adhesive. The polymeric material is such that it is ionically or electronically conductive or can be made so through use of an appropriate conductive additive. Suitable adhesives include wax, starch, methyl, carboxymethyl-, and hydroxyethyl-cellulose, locust bean gum, gum arabic, gum karaya and gum tragacanth; vinyl polymers preferably polyacrylamide, polyacrylic acid, polyvinyl pyridine, polyvinyl methyl ether, methyl methacrylate and polyvinyl pyrrolidone; polyphosphates; epoxy-amine, melamine formaldehyde and phenolic formaldehyde resins. The ionically conductive polymers can be used as adhesive electrolytes, e.g. the reaction product of polyacrylic acid or polyacrylamide with urea and acetamide. The polymer adhesives can also be used in combination with liquid electrolytes, e.g. aqueous solutions of NH 4 Cl and ZnCl 2 . The cells may be of the Leclanche type or the anode may be made of Ag, Mg, Cd, Cu, Pb, Mn or Al and the cathodic material may be the oxides of Ag, Cu, Ni, Hg, Ce, Pb, the halides of Ag or Cu, LiClO 4 , polyhalides, p-benzoquinone, m-dinitrobenzene, mnitrosobenzene, azo-dicarbonamide, t-butyl peroxyacetate, or perylene-iodine or phenothiazineiodine complexes. Other suitable electrolytes include solid silver sulphide iodide and aqueous solutions of NH 4 Cl, KOH, NaOH, H 2 SO 4 , HCl, sulphamic acid and sulphamates with gelling agents. Preferred cathode collectors are resinous materials impregnated with carbon particles, or a flexible graphite material. In the embodiment shown in Fig. 1, the internally bonded unit cell comprises a zinc anode 12, cathode 14 of MnO 2 , carbon and a binder, a cathode collector 16, electrolyte layer 18 and separator 20. The adjacent layers are held together in physical and electrical contact by adhesive 22a, 22b, 22c.

Abstract: 1297143 IGFETs FAIRCHILD CAMERA & INSTRUMENT CORP 21 Nov 1969 [16 Dec 1968] 57202/69 Heading H1K A MOSFET comprising diffused source and drain regions in a silicon substrate of opposite conductivity type has a gate electrode of silicon formed by decomposition of silane in a hydrogen atmosphere at a temperature between 630‹ and 680‹ C., and doped with 10<SP>17</SP> to 10<SP>19</SP> impurity atoms/c.c. This affords a transistor with a low turn-on voltage and a high ratio between the voltages required for inversion beneath the lead and gate respectively for comparable thickness of insulation. A typical device is formed on a 111 or 100 N-type silicon substrate by first oxidizing the surface to give a layer thinner over the channel, growing amorphous silicon as described above after pretreatment to provide nucleation centres and diffusing it with donor impurity, depositing further silica overall, forming holes in the layers and diffusing therethrough to form source and drain regions and finally growing further oxide and aperturing for provision of deposited aluminium contacts. To form a P-gate device the silicon is selectively deposited at the gate site and an overall oxide layer deposited and apertured there and at source and drain sites and boron diffused in to simultaneously form the source and drain and dope the gate. An integrated complementary MOS inverter circuit is described in which one transistor is formed in an N-type wafer and the other in a P-type island therein, the gate electrodes meeting in a PN junction which is bridged by a common contact. Reference has been directed by the Comptroller to Specification 1,186,625.

The apparatus may be used for the construction of underwater or underground pipe-lines. The telescopic means may comprise a series of alternating outer and inner tubes 11, 12 having end stops which limit relative longitudinal movement. The outer tubes carry at their outer ends sets of three or more radial arms 13 having rollers 14 engageable with the pipe section interiors and, if desired, the arms or the rollers may be spring mounted. The control line section coils may be connected between junction boxes 19, 20 on the outer tubes 11, directly or via intermediate boxes 21 on the inner tube 12. The crawling clamp may be hydraulically, pneumatically, or electrically propelled and clampoperated. The crawler 10 may be hydraulically or pneumatically propelled, the control lines then including hoses, or electrically propelled (e.g. as shown by a D.C. motor 15 driving pipe engaging wheels 16). The control lines extend from a junction box 24 through the clamp and out to an external control unit 26. The crawler carries an X-ray generator tube 18 and a geiger counter 17 co-operable with a radioactive isotope 17a disposed externally of the pipe sections at a predetermined distance from the weld seam to be radiographed.  In operation, the apparatus is disposed in the open end of a pipe-line under construction and the clamp is used to align and clamp pipe section ends together. Independently of the operation of the clamp, the crawler is driven along the pipe-line and located, using the geiger counter and isotope, to dispose the X-ray generator tube 18 opposite a weld seam, the tube then being operated to expose film disposed externally around the weld seam. In the event of breakdown of the crawler, the latter and the telescopic means 8 may be dragged from the pipe-line by an external winch, one of the wheels 16 being retractable to facilitate this. In an emergency, maximum energization of the clamp and crawler motors may supplement the winch effort.
