Abstract: ABSTRACT   A device for sensing the presence of and measuring the concentration of a specific non-aqueous particle or gas material in an environment, the device comprising an interdigitated capacitor having at least a pair of selected covering layers thereupon, said pair of layers comprising a first passive electrically insulative layer and a second material layer having a spacial relationship to said first layer, said second layer selectively permeable to the specific material to be sensed and measured; said second coating, when juxtaposed said first coating, selectively permitting permeability of the particular material sought to be sensed and measured, and when spaced apart, permitting passage through of the specific material in order that the material may migrate to the proximity of the first coating and thereby be sensed and measured.  The pre-sence of the specific material modifies the dielectric constant of the dielectric in the interdigitated capa-citor electric field and thus the capacitor's capaci-tance, whereupon the interdigitated capacitor's capacitance is compared with a proximate temperature sensing interdigitated capacitor in a capacitance sensing circuit and by the change of the capacitance, the presence and concentration of the specific material determined.

Abstract: ABSTRACT:             In a television receiver for a transmission system in which the vision signal and the audio/data signals are scrambled to allow only for their authorized reception, a  low rate encrypted signal present at an output (11) of a sound/data signal processor (10) is decrypted and employed to periodically set (say once every one or two seconds) a master pseudo random pulse generator (12B) producing an output of pseudo random configuration at frame rate.  It is used on the one hand to periodically set a vision slave pseudo random pulse generator (15) to produce an output of pseudo random configuration at line frequency.  This is applied to an input S of the vision processor (8) for the line-by-line de-scrambling of the vision signal.  The output of the master pseudo random generator (12B) is also used to periodically set a number of further slave pseudo random pulse generators (17, 18, 19) which produce outputs of pseudo random configuration at an intermediate frequency applied to inputs S1, S2, S3 of the processor (10) and which form the respective keys for the de-scrambling of the scrambled sound/data compo-nents.  The advantage obtained is that a low rate encryption key need only be transmitted to produce the required scrambling keys for both vision and sound/data.

Abstract: ABSTRACT OF THE DISCLOSURE         An integrated semiconductor circuit including a substrate consisting of silicon having a heavily doped impurity layer formed thereon.  An external contacting track level consisting of aluminum or aluminum alloy is connected to the contact regions by means of an intermediate layer consisting of tantalum silicide.  The tantalum content of the compound is greater than that required stoichiometrically to produce the intermetallic compound TaSi2.  The external contacting track level is preferably in the form of an aluminum or aluminum alloy-tantalum silicide double layer.          The tantalum silicide layer simultaneously acts as a diffusion barrier and as a contacting material.  The useful life of the electrical conducting paths under temperature and current loads as well as the reliability of the contacts is signi-ficantly increased in VLSI circuits as a result of this metallization.

Abstract: ABSTRACT      An electrostatic spraying apparatus in which an electrode is mounted adjacent to the sprayhead, means are provided for causing a first electrical potential to be applied to liquid emerging from the sprayhead, and further means are provided for applying a second electrical potential to the electrode.  The difference between the first and second potentials is sufficient to cause an intense field to be developed between the emerging liquid and the electrode, sufficient to atomise the liquid.  The electrode has a core of conducting or semi-conducting material sheathed in a "semi-insulating" material.  This "semi-insulating" material has a dielectric strength and volume resistivity sufficiently high to prevent sparking between the electrode and the sprayhead and a volume resistivity sufficiently low to allow charge collected on the surface of the material to be conducted through the "semi-insulating" material to the conducting or semiconducting core.

Abstract: STEERING AND CONTROL SYSTEM FOR PERCUSSION BORING TOOLS     ABSTRACT OF THE DISCLOSURE       A steering and control system is disclosed for per-cussion boring tools for boring in the earth at an angle or in a generally horizontal direction.  The steering mechanism comprises a slanted-face nose member attached to the anvil of the tool to produce a turning force on the tool  and movable tail fins in the trailing end of the tool to be selectively positioned relative to the body of the  tool  to negate the turning force.  The fins assume a neutral position relative to the housing of the tool when the tool is allowed to turn and to assume a spin inducing position relative to the hous-ing of the tool  to cause it to rotate when the tool  is to move in a straight direction. The tool optionally has a cyl-indrical body with overgage sleeves located over a portion of the outer body affixed so that they can rotate but cannot slide axially.   The overgage areas at the front and back of the tool, or alternately, an undergage section in the center of the tool body permits a 2-point contact (front and rear) of  the outer housing with the soil wall  as opposed to the line contact which occurs without the undercut.   The 2-point contact allows the tool to deviate in an arc without distort-ing the round cross-sectional profile  of the pierced hole.          Thus,  for a given steering force at the front and/or back of the tool, a higher rate of turning is possible since a small-er volume of soil needs to be displaced.   A control  system guides the tool  in a borehole   in response to control sig-nals.   The control system includes an axial electromagnetic source  for  generating  an axial  alternating magnetic field directed along  an axial  source  axis.   A sensing  assembly remote from the source means includes first and second pickup coils for sensing the alternating magnetic field.   Each of the first and second pickup coils has a respective coil axis and is rigidly mounted in respect to  the other with their respective axis at a substantial angle with respect to each other, defining a sensing assembly axis substantially normal to both coil axes.   Each coil  generates a respective null electrical signal  when the  lines  of magnetic  flux at  the respective  coil  are  normal  to  the  respective  coil  axis.          Either the source or the sensing assembly is rigidly mounted on the tool, preferably the source.  The outputs of the sens-ing coils are used to determine the  direction of lines of magnetic flux at the sensing assembly, and indicate the atti-tude of the source relative to the sensing assembly.
