Patent GB-1053713-A (GB)
IPC: F41G7/30
Abstract: 1,053,713. Controlling guided missiles. NORD-AVIATION SOCIETE NATIONALE DE CONSTRUCTIONS AERONAUTIQUES. Feb. 27, 1964 [Feb. 27, 1963], No. 8305/64. Heading B7G. [Also in Division G1] A jet-propelled guided missile (not shown) controlled from a manually operated remote control station over control wires 6, 10 is designed to rotate about its longitudinal axis in flight and is controlled by a jetdeflector on the missile. The control station comprises a control stick 1 operated by a pilot who observes the flight of the missile towards a target by means of a telescope, the control stick producing two voltage signals Vz and Vr respectively representing Cartesian co-ordinates of any vertical and horizontal deviations of the missile from the sighting line, the signals passing through a network 2 which compensates for delays in the system. A gravity compensating signal Voz from unit 3 is added to signal Vz to maintain the missile in horizontal flight when no signals are generated at 1. The signals from 2 and 3 pass through a co-ordinate changing stage 4 which gives output signals V and V 2  fed to an adding stage 11. The missile includes means, e.g. a gyroscope, for producing a signal each time that, during rotation of the missile, the pitch control means passes through a specific angular position about its longitudinal axis, the signal being received through wire 6 by the control station to synchronize a sawtooth generator 7, the maximum amplitude being maintained at a constant voltage by a regulator 8 comprising two equal value capacitors so interconnected that energy will be transferred from one to the other when a reference signal is received from the missile, to regulate the slope of the signal developed by sawtooth generator 7. The output at 7 is fed to adding stage 11 to inter-act with signals V 1  and V 2  to produce a square-wave voltage transmitted at 10 to control the operation of the jet deflector on the missile. A delay compensation circuit 13 is included in the control station to advance angularly the position of the squarewave order signal by an angle proportional to control surface delay and missile rotational frequency. Since gravity will cause downward deflection of the missile, means is provided in the missile to inhibit control signals through a sector of its rotational movement, this sector being used for transmission of missile reference signals, thereby avoiding simultaneous transmission over the control wires of control signals and reference signals. Prior to launching an internal pulse generator 15 supplies sawtooth triggering pulses and a circuit 14 supplies the gravity compensation signal Voz to a memory 17 connected to adding stage 11, these being disconnected upon launching by a solenoid operated switch 16 which simultaneously closes a switch connected by a power supply 19 to a stage 18 for eliminating the missile pulses during the launching phase when the rotational speed of the missile is varying rapidly.

Abstract: 1,233,791. Stereophonic pickups. NIPPON COLUMBIA K.K. 19 June, 1968, No. 29246/68. Heading H4J. A stereophonic pickup comprises a plate 3 (Figs. 1, 2) magnetized in the direction of its thickness. A cantilever 1 has one end fixed in the plate 3 and projects from a major surface of the plate 3. Its other end supports a stylus 2. A pair of cores 4L, 4R are adjacent to and separate from the plate 3. Signals are inducable in windings 5L, 5R on the cores 4L, 4R when the plate 3 vibrates relative to the cores 4L, 4R. The longitudinal axis of the cantilever 1 passes through the centre of gravity of the plate 3. The cantilever 1 is anchored to the support 7 to constrain its longitudinal movement when vibrated. Preferably the cantilever 1 is anchored to the support 7 by fine wire 6. A damper 8 between the plate 3 and support 7 provides a resilient mounting. The wire 6 secures the cantilever against longitudinal movement and ensures that the centre of vibration of the vibration system including stylus 2, cantilever 1 and plate 3 lies substantially at the centre of gravity of the plate. The cores 4L, 4R may be E-shaped or U-shaped. Where they are E-shaped there may be a single winding on the centre limb or windings on the outer limbs. The outer limbs may be bent inwardly (Fig. 9, not shown). Alternatively, pot-shaped cores having an E- shaped cross-section may be used. The cores may be above or below the plate 3 or there may be four cores, two above and two below plate 3 (Fig. 8, not shown). The plate 3 may be square, circular, cross-shaped or octagonal (Fig. 11, not shown). A plurality of cylindrical members I 1 , I 2  . . . &c. may be mounted about the cantilever 1 to prevent undesired cantilever vibration. The pickup support 7 (Fig. 12) may have a rod R inserted in a hole H in a base-plate S. Base-plate S has a groove corresponding to the shape of support 7. This arrangement facilitates stylus replacement.  Reference has been directed by the Comptroller to Specification 897,323.

Abstract: 1,238,072. Photographic materials and their use in making half-tone images. KALLE A.G. May 24, 1968 [May 26, 1967], No.24961/68. Headings G2C and G2M. A method of producing a half-tone printing plate wherein a light-sensitive material is exposed to light under an original, the light passing before it reaches the upper surface of the light-sensitive layer through a contrast layer comprising randomly or regularly distributed areas having a maximum diameter between 0À5-10 microns and being at least 10% and at most 90% of the total area of the layer, these areas contrasting in lighttransmission capacity with their immediate environment, removing the contrast layer if coated on or in contact with the light-sensitive layer before or during developing and, if desirable, etching. In the examples, a support, such as roughened aluminium or polyester support, is coated with a light-sensitive layer (e.g. a naphthoquinone diazide sulphonic acid ester, a p-imino-quinone diazide, cinnamoyl epoxide resins or azide compounds in polymeric binder) is dusted with a pigment such as carbon black 5-10 microns in diameter. Alternatively, the pigment may be incorporated in a water-permeable overcoated layer or in a layer on a separate sheet which is placed on top of the light-sensitive material. Pigments may be replaced by particles of metal dispersed in a binder and coated on the light-sensitive layer. The light-sensitive material with its pigment or metal overcoating or in contact with a sheet containing such a pigment or metal is exposed to a photographic stop tablet, the pigmented layer if coated or dusted on the material is washed off and developed and inked. Similar material not containing pigments or metal coatings produce less stop on development but require less exposure time. An alternative method of exposure is a 20 second pre-exposure without the stop tablet and a minute exposure with the stop tablet. Other specified contrast layers are silica in a polymeric binder as an overcoat or a separate sheet, barium sulphate or silver in a polymeric binder used as an overcoated layer and yellow pigment in a polymeric binder as an overcoat or a separate layer.

Abstract: 1,252,768. Mechanical switches. TEXAS INSTRUMENTS Inc. 8 April, 1969 [5 April, 1968], No. 17818/69. Heading H1N. In an electric switch the operating member maintains the contacts open during its foward movement and, during its return movement, first closes and then opens the contacts. In the form shown, moving contact 5 is pivoted on the end of a flat member 3, integral with terminal 1, and co-operates with fixed contact 11 on terminal 10. Operating lever 32 projects through a slot 33 in casing 2 and is joined to a block 15, slidable in the casing 2 and carrying a spring-loaded plunger 12 which bears on the underside of moving contact 5 and, in the unoperated position (Fig. 2), holds the contacts open. Lever 32 is biased to this position by spring 24. - Block 15 has two parallel faces 17, 18, which, in the unoperated position, may slide along the inner surfaces 20, 19 of the casing 2, and also two other similar parallel faces, at an angle to the first two, which similarly form sliding surfaces when the block 15 is tilted as in Fig. 5 (not shown). When lever 32 is forwards, towards the right, block 15 initially tilts and, as it does so, a tooth 22 on the block engages over moving contact 5 so that as lever 32 and block 15 are moved towards the right, tooth 22 holds contact 5 away from contact 11. When block 15 is fully forward, tooth 22 continues to hold contact 5 away from contact 11. When lever 32 is released, spring 24 moves it in the return direction, first tilting block 15 so that faces 17, 18 again engage surfaces 20, 19 and, at the same time, moving tooth 22 away from contact 5 to free the latter and allow plunger 12 to thrust it against contact 11. During that part of the return movement between the fully operated position and the point at which plunger 12 passes beneath the pivot formed by member 3, plunger 12 maintains contact 5 against contact 11 but, when this point is passed, plunger 12 tilts contact 5 back to its initial position to open the contacts. The switch may be mounted on a washing machine door, see Figs. 9, 10 (not shown).

Aperture opening or closing movements of slidable diaphragm plates 12, 13 which have co-operating apertures 15, 18 and 17, 16 to cover or uncover lens aperture 26 and photocell aperture 27 provided in a plate 14 is controlled via rack and pinion gearing 19, 20 and 6<SP>1</SP> by a continuously rotating drive roller 11 engaging either the outer or inner surface of a groove 9 provided in a pulley 8. The pulley 8 has a gear 10 which engages the gear 6, and the pulley is mounted for rotation about a pin 7 provided on an armature arm 4. The armature arm is associated with two electromagnets 1, 2 and attraction of the armature from one electromagnet to the other causes relative movement between groove 9 and drive roller 11 to thus reverse the direction of drive of gear 6, upon neither electromagnets being energised a spring 4<SP>1</SP> biases the armature arm into an intermediate position in which no drive is transmitted from roller 11 to pulley 8. The photo-resistor Pc controls the switching of two Schmitt Triggers which are connected to the electromagnets, the circuit arrangement being such that at low light levels one electromagnet is energized so that the apertures are opened until the photo-resistor receives sufficient illumination to de-energize the electromagnet and a neutral state is reached. If too much illumination reaches the photoresistor, the other Schmitt Trigger switches over to energize the other electromagnet so as to close the apertures until a neutral state is again achieved. Any type of exposure regulate such as those which change the shutter speed or diaphragm aperture or both may be used in place of the slide plate type of exposure regulator illustrated. The drive roller 7 may be coupled to the drive motor of a cine camera.
