Title: Image Motion Stabilization System
IPC: F41G3/22
Filed: 1966-06-08
Abstract: 1,154,882. Sight. ITEK CORP. 8 June, 1966 [8 June, 1965], No. 57503/68. Divided out of 1,154,881. Heading F3C. [Also in Division H4] A fire control system employs photosensitive means (e.g. an image converter or image intensifier tube) carried by the barrel of a weapon to produce an image of a target together with image deflection means supplied from sensors responsive to motion of the photo-sensitive means to provide signals which deflect the image in a direction to cancel motion of the latter caused by motion of the photosensitive means and which operate means for firing the weapon when the displacement of the axis of the barrel from the target axis due to such motion is within pre-determined limits. The invention is described in connection with stabilizing the image in the eyepiece of a telescopic rifle sight (Fig. 3), against random angular motion of the weapons about the optical axis. The sensors, which provide signals indicative of the sign and magnitude of motion (i.e. instantaneous position) in rectangular co-ordinate directions X, Y, comprise rate gyros with associated integrating amplifiers. In the basic arrangement of Fig. 1, resistors 15 and 20 are shunted across the integrating capacitors of the integrating amplifiers 16, 19 to prevent the image deflecting means from responding to signals (of about 2 c.p.s.) produced by slow panning. In operation the criterion for "on-target" is zero output from the X and Y integrating amplifiers. Such conditions when sensed by respective trigger amplifiers 67, 69 (Fig. 4), each having the response of Fig. 5, provide the two inputs to an AND gate 78, which if not inhibited by an input on line 88, operates a trigger solenoid 71 to fire the weapon. Such inhibition is effected when the rifle is swung from right-to-left or vice-versa with a velocity exceeding a pre-determined amount by the circuit of Fig. 7 comprising clippers 83, 84 providing signals representative of such motion and controlling respective multivibrators 86, 89 which supply inputs to an OR gate 87 whose output is connected to the inhibit line 88. The arrangement of Fig. 7 may be duplicated for inhibition in respect of vertical motion. The gate 78 may be further inhibited by means of a switch 94 which when closed supplies a positive inhibiting potential to line 88 from the metallic rifle frame portion 96 until a predetermined minimum pressure is applied to the trigger 93 to interrupt the inhibiting potential by the open. ing of contact 99. As the latter contact opens a second contact 100 closes and via a closed switch 95 linked to switch 94 energizes relay 105 which operates to disconnect the resistor 91 shunting the integrating amplifier capacitor and thus allow the deflection control circuitry to respond to panning so that automatic firing of the rifle when the sights are off target is prevented. A further contact may be provided which, when the trigger is pulled back to its extreme position, allows over-riding of all the circuitry and manual (via the electrically controlled trigger solenoid) firing of the rifle.

An elastomeric material layer may be disposed between the metal plates and bodies of the inorganic material. The pockets 8 and 9 in the vest 7 are disposed so that the inserts 10 overlap one another to provide a compact protective surface.

Abstract: 1277568 Sealing glass to quartz or silicon carbide; SiC layers PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 16 Dec 1970 [19 Dec 1969] 59705/70 Headings C1A and C1M [Also in Divisions C4 and H1] A conductive layer on the window of a cathode-ray display or pick-up tube comprises silicon carbide made conductive by donor or acceptor substances, this layer forming a substrate for luminescent or photo-conductive material. The window may be entirely of silicon carbide sealed to the envelope by an intermediate part of borosilicate glass, or it may be a layer of silicon carbide on a quartz plate sealed in known manner to the envelope with intermediate glass parts if necessary. In one example silicon carbide obtained by pyrolysis of a methyl-chlorosilane is sintered at 2200‹ C. for one hour in a graphite mould in argon containing less than 1 p.p.m. of nitrogen, and is subsequently heated at 2500‹ C. for 5 hours in a graphite crucible in helium containing less than 0À1 p.p.m. of nitrogen to grow crystals. One surface of a crystal is made conductive by diffusion of aluminium into it to give a resistivity of 0À5 ohm cm., and contacts are provided by melting strips of gold containing 5% tantalum on to the surface. In another example silicon carbide powder is heated at 2600‹ C. in an atmosphere of argon containing 0À01% nitrogen in a graphite crucible; a silicon carbide layer sublimes on to the lid which is at 2400‹ C., and after the carbon is burnt away in an oxygen atmosphere wafers are formed by grinding and sawing the layer. The layer has a resistivity of 1 ohm cm. due to the nitrogen doping and contacts are made by melting an alloy of nickel containing 10% molybdenum on to the wafer. In a further example a graphite plate is heated at 1550‹ C. in a flow of hydrogen containing 1% methylchlorosilane; nitrogen in the gas stream causes the resultant silicon carbide deposit to be conductive and have a resistivity of 200 ohm cm. In a final example a quartz disc is covered with a carbon suspension which is dried and heated to 110‹ C. in hydrogen for 8 hours to form a surface coating of silicon carbide; the disc is heated again in oxygen containing 1% nitrogen to burn away residual carbon and to make the surface conductive. If the tube is a vidicon, a layer of vapour-deposited lead monoxide is provided on the conductive surface, and for a display tube a layer of willemite is deposited on the surface.

The tail of the screw thread; engages the tapped bore of a ring 6 trapped in the cavity 16 but pivotable about ridges 24 in upstanding wings 23 of a U-shaped trough 2 which constitutes a body having- an input face 20. Rotation of the screw 5 causes it to advance, driving a mobile jaw 4 which, by engagement of its lugs 10 in slots 19 of the. wings 23, is guided down at an angle steeper than that of the screw axis, to clamp the conductor 7 against serrations on the fixed jaw 3. All movable members are captive in a main housing 1. Damage due to excessive backward rotation of the screw 5 is avoided by the termination of the thread which leaves only the plain end 15 engaged when the jaw 4 meets the stop 14. In. a modification (not illustrated), the tail of the screw (5) is captive in the ring (6) and the mobile jaw 4 has an internal thread enabling it to be advanced by engagement with the thread of the screw 5.

The pilot valves also control a by-pass line 47 connecting opposite ends of the hydraulic cylinder together so that with valve 11 in neutral and valves 14, 15 unenergized the piston 35 may be moved mechanically to any desired position. In the piston position shown, energization of say valve 14 opens line 44 and hence chamber 25 to drain and results in spool 16 being moved to the left and supply of pressure fluid to cylinder chamber 39 which thus moves piston 35 to the left until when it passes beyond line 44 the piston stops.
