Patent GB-1287624-A (GB)
Title: Information display systems
Inventor: JONES PATRICK LUDLOW FLEMING
IPC: G02B27/01
Filed: 1969-08-21
Abstract: 1287624 Head-up displays SPERRY RAND Ltd 20 Nov 1969 [21 Aug 1969] 41664/69 Heading G2J A head-up display for an aircraft comprises an illuminated source of information 16 an image of which is collimated by a spherical mirror 21 and projected on to a partially reflecting mirror 15 so allowing a user 18 to view a virtual image of the source at infinity and within this line of sight 25. The source includes a line arranged to appear to be overlying the true horizon, a glide slope director line 12 which subtends a constant angle e.g. 3 degrees at the pilot's eye with respect to the horizon line 11 and a shorter flight path vector line 14 which is co-linear with the upper line in level flight and co-linear with the lower line when moving along the 3 degree glide slope path. The lines are formed by rows of small lamps in a graticule box 16, arranged in the focal plane of mirror 21 which is made with a 75% transmitting and 25% reflecting neutral titanium oxide layer facing the user, and a reverse side which is bloomed. The mirrors 15 and 21 are movable between stowed and deployed positions, switches being provided on the mirrors to prevent energization of the system until the deployed position is reached. To provide roll stabilisation, the graticule box is rotatable about axis 20 and by mounting mirror 15 on trunnions pitch stabilization may be achieved; sensors on an inertial platform or gyros providing the appropriate attitude signals. The row of lamps forming the flight path vector line are arranged to be relatively movable with respect to the other lines, and when closing on the other line positions this row appears red. The movement of this line is through a servo actuated by a signal computed from both the pitch and angle-of-attack sensors. Pilot control of the display can lead to information on the degree of roll and to variation in brightness level of the source; the latter may also be reduced by arranging diffusing slits in front of the source. Long filament lamps or fibre optic systems may be used for illumination, and filters may be interposed in the light path. To ensure good alignment, the mirrors 15, 21 may be linked to form a removable non-folding unit. Mirror 15 may be fixed, in which case pitch stabilization is achieved by the relative movement fore and aft, on a carriage, of the lamps representing the horizon line 11 and glide slope 12 within the box 16. In a simplified display, the glide slope line alone can be used or the glide slope and flight path vector lines are used in combination these being means for adjusting the glide slope with respect to the horizon.

Title: Acoustic hologram recording systems
IPC: G01H3/00
Filed: 1974-09-30
Abstract: 1488142 Acoustic holography SIEMENS AG 30 Sept 1974 [19 Oct 1973] 42301/74 Heading G1G An acoustic hologram recording system is characterized in that either the ultrasonic transmitter or receiver is directional, mounted for rotation about at least one axis, and surrounded by a parabolic acoustic mirror. In the Fig. 1 embodiment, transmit transducer 2 is at the focus of paraboloidal mirror 3 and is rotatable about orthogonal axis x, y to provide scanning of a focal spot F 1 over selected plane x', y' of object 1. Transducer 5 receives reflected energy and its output is mixed with a reference signal. The resultant hologram signal is recorded, on film or erasable material, by an oscillograph as a function of the spot position. The transducer 2 rotation is about a single axis in the Fig. 2 embodiment. The transducer generates a fan-beam which is directed by cylindrical parabolic mirror 3' on to object 1. Rows of transducers 5 receive the reflected energy. The transducers in any given row are interrogated sequentially by electronic switch 6 and their outputs are mixed with a reference signal from generator 8. The mixed signal is recorded on oscillograph 12, whose x and y deflections are synchronized respectively with the transducer 2 rotation and the transducer 5 switching. In modifications (a) the receive transducer is rotated instead of the transmit transducer, (b) monodimensional holograms are recorded by using a pulsed ultrasonic transmission and recording echo amplitude (after mixing with the reference signal) as a function of echo time, the successive recordings corresponding to successive rotational positions of the transmitted beam, and (c) a modulated laser beam is used instead of the oscillograph to record on photographic film or a thermoplastic.

IPC: C08K7/00
Filed: 1964-10-28
Abstract: In moulding processes where polyolefines such as polyethylene or polypropylene having a molecular weight of more than 120,000 are plasticized mainly by the effect of frictional heat, e.g. in extrusion and injection moulding, the polyolefine is supplied to the moulding machine in the form of sintered granules together with 0.05-5.0% by weight of a lubricant. The lubricant, which is said to increase the throughput of material without degradation or melt fracture thereof, is an organic or inorganic substance which crystallizes into a layer lattice structure and may be the salt of a monovalent to tetravalent metal with a saturated or unsaturated carboxylic acid, e.g. sodium, zinc or cobalt stearate, or, as examples of an inorganic substance, graphite, graphitic acids, molybdenum disulphide, magnesium silicate or boron nitride.  The starting material may be obtained by conventionally mixing the sintered granules and lubricant or by applying an atomized solution of the lubricant to the granules.
