Abstract: 1,206,684. Electric selective signalling. BUNKER-RAMO CORP. 10 Sept., 1968 [29 Sept., 1967], No. 42980/68. Heading G4H. A chart such as that shown in Fig. 1 having regions representing, for example the contours of an area, a change from a black to a white region, i.e. 20 to 21 representing an increase in altitude whilst a change from a white to a black region, i.e. 30 to 29 representing a decrease, is scanned along a path ST the resulting signals from the scanning member (which when the regions have differing reflective or transmissive qualities is a photomultiplier 48 (Fig. 3)) being fed to a signal decoder 52 which compares each signal with the previously received signal to feed a count up or a count down pulse to a reversible counter 55 the count in which thus represents the altitude of the area currently being scanned. In the embodiment described the signal encoder includes an analogue/digital converter (62, Fig. 4, not shown) delivering a parallel two-bit signal (A, B) representing white, grey or black. This is compared with the previous signal in AND gates (72-78, Fig. 7, not shown) the outputs from which control via OR gates (75, 79) the counter 55 (Fig. 3). The counter may be connected to a tape 57 or a digital/analogue converter 58 controlling a displa,y 60 (e.g. a plotter or an oscilloscope). In the application of the invention for determining the area covered by an antenna 82 (Fig. 8) at a position X 0 , Y 0  and of height Ha a radial scan is made at an angle # by feeding a varying range signal R and a fixed signal representing # to a function generator 85 controlling, via adders 86, 87 receiving signals X 0 , Y 0 , the scanner and a plotter 92. As the scan is effected, the height of the antenna is subtracted from the altitude signals generated by digital/analogue converter 58 and a signal representing # where is generated and fed via a diode (104, Fig. 10, not shown) to a capacitor (103). When the charge on the capacitor is not increasing, i.e. # is a decreasing function (indicating that the area being scanned is not visible by the antenna) the plotter plots a line 107. The process is repeated for other angles # so that the area 110 not covered by the antenna is indicated.

Filed: 1963-10-31
Abstract: Thiocarbamates may be prepared from a halocarbonylsulphenyl halide of general formula <FORM:1019485/C2/1> wherein X is a halogen atom.  In an example S - ethylthio - N - methyl - N - phenyl - thiocarbamate is prepared from chlorocarbonylsulphenyl chloride, <FORM:1019485/C2/2> ethyl mercaptan and N-methyl aniline.ALSO:Halocarbonylsulfenylhalides, having the formula <FORM:1019485/C1/1> wherein X is fluorine, chlorine, bromine or iodine, are prepared by thermal dehalohydrocarbylation of a compound of the formula ROCX2SX wherein R is a hydrocarbyl group and the carbon bonded to the oxygen is a saturated aliphatic carbon.  R may contain cyano, halo or nitro substituents.  Catalysts for the ionic halogenation of benzene, i.e. electrophilic substitution, e.g. iodine, SbCl3 and FeCl3, in amount 0.1-2 mol. per cent, greatly accelerate the dehalohydrocarbylation and enable a lower temperature range e.g. - 50 DEG  to 50 DEG  C. to be used. A solvent e.g. ethers, CHCl3, CS2 and low boiling hydrocarbons may be used. Chlorocarbonylsulfenyl chloride is prepared by heating at 40-200 DEG C. a hydrocarbyloxydichloromethanesulfenyl chloride, e.g. ROCCl2SCl where R contains 20 C atoms or less, say 1 to 6 such as methyl, ethyl, propyl, isopropyl, butyl sec-.butyl, isobutyl or tert.-butyl, until hydrocarbyl chloride evolution ceases.  This evolution is facilitated by sub-atmospheric pressure e.g. 75-500 mm.  Hg. Chlorocarbonylsulfenyl chloride may be distilled after hydrocarbyl chloride evolution.  Alternatively, the fluoro, bromo and iodo analogues of <FORM:1019485/C1/2> may be prepared by exchange with <FORM:1019485/C1/3> and a salt of the hydrohalic acid.

The base region of a transistor emerges at a planar surface thereof through apertures 51 in the emitter region 52. The width of each aperture 51, viewed in a direction along rows into which the apertures are arranged and perpendicularly thereto, first increases then decreases, the preferred aperture shapes being circles or diagonally arranged squares as illustrated. The apertures of each row are contacted through windows 59 in an insulating layer by one digit 56 of a base electrode comprising a series of such digits connected together at one end and interdigitated with similar digits 58 of an emitter electrode, which latter digits contact the emitter region 52 through windows 57 in the insulating layer situated centrally between four adjacent apertures 51. In the preferred embodiment the base region is formed by boron-diffusion into an epitaxial N-type Si layer on a low resistivity N-type Si substrate, and the emitter region 52 is then formed by phosphorus-diffusion into the base region through an oxide or nitride mask having an array of spaced or just-touching holes (70), Fig. 6 (not shown). Lateral diffusion under the mask causes the phosphorous-containing areas to merge together, forming a network which constitutes the emitter region and which encloses the surface-emergent base portions. The electrodes, including the digits 56, 58, Fig. 5, may be of Al, and may additionally contact the base and emitter regions respectively outside the intermeshed surface area. Part of the thickness of the low-resistivity N-type substrate may be etched away. The invention may also be used in an entirely diffused transistor, and Ge or III-V compounds may be substituted for Si. The transistor may also comprise part of an integrated circuit.

Abstract: 440,980. Gyroscopic apparatus; magnetic compasses. SPERRY GYROSCOPE CO., Inc., Manhattan Bridge Plaza, Brooklyn, New York, U.S.A.-(Assignees of Peterson, J. B.) Dec. 10, 1934, No. 35437. Convention date, Jan. 22. [Classes 97 (ii) and 97 (iii)] In a gyromagnetic compass, in which a magnetic element mounted on a directional gyroscope con trols the average position of the gyroscope in azimuth, the rotor casing is pendulously pivoted about an axis parallel to the spin axis as well as about a perpendicular neutral, horizontal axis. In the form shown, the air driven rotor 8 is mounted on a normally N-S horizontal axis in a casing 6 which is pendulously suspended about an axis parallel to the axis of spin in a horizontal ring 52. The latter is pivoted in the vertical ring 51 about an E-W axis 52<1> passing through the average position of the centre of gravity of the rotor casing and ring 52 during normal swinging of the gyro about the N-S axis. A disc 16, carrying magnets 57 and pivoted at 17 between the top of the casing 6 and a U-shaped member 24 on the casing 6, is provided with depending skirts 18, 18<1> adapted to differentially cover air jet orifices 55, 56, in the casing 6 and cause the gyro to precess into a predetermined position relative to the disc 16. A compass card is fixed to the ring 51. In order to maintain the spin axis in the azimuth plane a pendulum 54 pivoted in the casing 6 differentially covers orifices 22 leading to jets for exerting an erecting torque about the vertical axis. Preferably a cam driven through reduction gearing from the rotor spindle operates means for intermittently clutching the magnetic element to the rotor casing and carries screens to obstruct the jets 55, 56 whilst the magnetic element is free. The sequence of operations performed by the cam is (1) to move a lever, biassed to the disengaged position into contact with the disc 16, (2) to move a second lever, biassed to the engaged position, out of contact with the disc 16, (3) to release the first lever so that the disc is free, preferably for a time equal to one quarter of its period of oscillation, and (4) to release the second lever which reclamps the disc 16. The Specification as open to inspection under Sect. 91 describes a construction in which the gimbal 52 is dispensed with and the casing 6, within which the rotor spins on a normally E-W axis, pivots about a N-S axis in the vertical ring 51. This subject-matter does not appear in the Specification as accepted.

Title: Process for the manufacture of multi-layer sheet materials
IPC: B32B27/00
Filed: 1960-12-22
Abstract: A coated sheet material consisting of at least two layers of different plastics is produced by applying aqueous dispersions of the different plastics to a smooth support, and drying in succession thereon under temperature conditions such that each plastic coalesces to form a homogeneous layer and the coated sheet material is thereafter removed from the support.  The aqueous dispersions may be applied to the support by disseminating them in the air in the form of fine particles, charging the particles in a high voltage electrostatic field and causing the charged particles to deposit on the support, which is oppositely charged.  The process may be carried out on a continuously moving support, the successive operations of applying and drying the dispersions being carried out in a continuous manner in successive zones distributed along the length of the support, and the coated sheet material is removed from the end of the support.  The support may be an endless belt which is heated over at least a part of its run, and the coated sheet material is removed from a terminal portion of the heated run.  The coated sheet material may be stretched after production or between the formation of successive layers.  Plastics referred to are vinylidene chlorideacrylic acid methyl ester, and butadieneacrylonitrile copolymers.
