Abstract: 1,259,664. Projection printing apparatus. FERRANTI Ltd. Aug. 5, 1970 [Aug. 12, 1969], No.40274/69. Heading G2A. [Also in Division B6] A project on printing apparatus comprises a light source 11; a projection gate having an objectplane locating surface 31; a projection lens system 23; a magazine disc 41 having a plurality of apertures 42 each carrying a displaceable ling member 44, each member 44 carrying a plate 46 bearing a symbol to be projected on to a photo-sensitive surface 24; a motor 63 and gearing 64 for rotating the disc so as to bring each aperture 42 in turn into approximate alignment with the optical axis 25; and displacement means for displacing the bezel member 44 so aligned thereby to bring the plate 46 thereof into the object plane 21 by bringing a surface (51) Fig.4, (not shown) into contact with the object plane locating surface 31. Sequence of operation. After the motor 63 has brought the required symbol into approximate alignment with the axis 25, a solenoid 72 is energized to flex a beam 67 upwards, thereby raising a tube 65 of the displacement means into contact with a surface of the member 44, thereby accurately aligning the plate 46 with the axis 25. Further upward movement of the tube 65 raises the member 44 out of the aperture 43 and brings the surfaces (51), 31 into contact. Continued upward movement of the tube 65 carries tube 26a and the member 44 in contact with the surface 31 thereof towards a tube 26b against the pressure of spring 71 until surface 38 engages the tube 26b, at which time the plate 46 is located in the object plane 21. A motor 34, which rotates tubes 26a, 26b, is provided to rotate the symbol image, if required. Shutter 14 is operated to make an exposure. The solenoid 72 is then de-energized and the member 44 returned to its aperture 43. A slideway 81 may be provided for delivering members 44 into apertures 42. Alternatively, a series of interchangeable discs may be provided. The symbols may be alpha-numeric characters, or may be such as to produce a light spot on the surface 24, lines being drawn by setting up relative movement between the spot and the surface.

Abstract: 1,266,075. Frequency comparators. ALLMANNA SVENSKA ELEKTRISKA A.B. 28 July, 1970 [29 July, 1969], No. 36432/70. Heading H3A. In a frequency comparator circuit the two signals whose frequencies are to be compared are converted to square waves and applied to a logical " parity " circuit 4, the output from which is passed through a low-pass filter 8 to a differentiator 9 to produce an output dependent on the frequency difference. The output from the low-pass filter 8 has a triangular waveform, and the square wave resulting from the differentiation of this, has an amplitude dependent on the difference in frequency. This square wave is rectified by diodes 12, 14 and the resulting D.C. signal is fed via amplifier 15 to a level responsive switch 16. A further output, dependent on rate of change of frequency may be obtained via a second differentiator 17.

Abstract: 1,266,588. Fluid-pressure servomotor systems. DAIMLER-BENZ A. G. June 27, 1969 [June 28, 1968], No.32697/69. Heading G3P. [Also in Division Gl] In an electrical system for controlling the regulating element of a fuel injection pump of an I.C. engine, (see Division G1), the element is moved by a fluid-pressure amplifier in dependence upon an electrical signal representing the desired injection quantity. In Fig. 3, the electrical signal energizes a coil 20a to move the valve member 50 to the right and thereby connected the passage 53 to line 62 from which pressurized fluid causes a piston 54 to move to the left, and displace the regulating element (not shown). The piston 54 assumes a new equilibrium position in which a spring 58 connected between a lever 57 acted on by piston 54, and valve member 50 is in equilibrium with the axial force exerted by the coil. In Fig. 5, the coil 20b provides a resilient closure for a nozzle 63 which applies the pressure fluid to a piston 64 which acts on a follow-up piston 65 which in turn acts on the regulating element through a radial pin 66. In Fig. 7, the winding 20c displaces a tongue 67 towards one pole or other of a magnet depending on the direction of current. Nozzles 63c disposed on each side of the tongue control fluidpressure to the outer ends of a piston valve 64c which controls the pressure which acts on a servomotor piston 54c, which is connected by a spring 58c with the tongue.

Abstract: 1290358 Aerials THOMSON-CSF 17 Dec 1969 [18 Dec 1968] 61493/69 Heading H4A An aerial comprises a primary source 1, Fig. 1, which directs linearly polarized waves towards a grid of parallel conductive wires 3 in a radome 2. As described, the radome is of parabolic form, and the wires are horizontal. Spherical waves with horizontal polarization are received from the source, and are reflected back as plane waves, to be received by a network of re-radiating sources 4. Each of said sources effects an orthogonal transformation of polarization between its input and its output, which are connected together by variable phase shifting means. Consequently, the re-radiated plane waves are vertically polarized, so that they pass through the wires 3, and they may be scanned in elevation, or in azimuth and elevation, by suitably varying the phase shifting means. A source 4 may comprise crossed dipoles, or a rectangular horn (Fig. 2, not shown). The phase shifting means 7 may comprise semi-conductor diodes, or ferrites. In another embodiment, a non- parabolic radome is used, so that the waves received by the re-radiating sources are non- planar. However, by suitably adjusting the phase shifting means, the re-radiated waves may be made planar, with reduced side lobes.

Abstract: 1294847 Pipe &c couplings FPT INDUSTRIES Ltd 30 July 1971 [12 Aug 1970] 38776/70 Heading F2G [Also in Division H2] A coupling, e.g. a pipe or cable coupling, comprises detents in one part moved radially inwards into a recess in the other part by a sleeve movable on the one part, the coupling being disengaged by acting against two spring forces. In one form, a pipe connector 16 to which a hose &c. may be secured, has a peripheral groove 14 receiving detent balls 15, held radially inwards by a hand release sleeve 29 and caged in the end of a second sleeve 22 axially slidable on a second pipe connector 19. Broad splines (34), Fig. 2 (not shown), within the end 33 of the sleeve 29 engage two balls 15: by twisting the sleeve 29 against the bias of a torsion spring 31, broad grooves (35) between the splines (34) are moved over the detent balls 15, which are accordingly released so that the connector 16 can be withdrawn. Alternatively, on axial overload by a force between the two connectors 16, 19 the sleeve 22 is slidden downwards against the bias of a compression spring 28 held by a flange 27 of a cylinder 26 secured to the pipe connector: ultimately the detent balls 15 enter a flared mouth 37 of the sleeve 29, thus releasing the connector 16. As shown, valves 40, 40 at the ends of the connectors A, B close automatically as soon as the coupling is released. In one modification, Fig. 1 (not shown), the valves are omitted. In another modification, Fig. 7 (not shown), the torsion spring 31 is replaced by a compression spring (46), the sleeve 29 being slidden axially by hand to release the coupling. As a further modification, the torsion spring 31 is omitted, the spring 28 being used in compression as before but also being connected in torsion between the second sleeve 22 and the sleeve 29. In another form, Fig. 6 (not shown), a coupling similar to that described with reference to Fig. 5 connects electrical conductors (see Division H2).
