Title: Method of hot briquetting fine-grained substances and of further treating the hot briquettes
Inventor: WAGNER ARMAND
IPC: C22B1/245
Filed: 1984-12-03
Abstract: Fine-grained substances in the form of metal oxides charged with solid and/or fluid carbon carriers are heated in the flue stream, alone or mixed with additional non-caking solid carbon carriers, to about 600 DEG C and are then mixed with caking coal previously heated to a maximum of 360 DEG C. The mixture is detarred and briquetted at 500 DEG C +/- 40 DEG c and the briquettes are subsequently conveyed to pyrometallurgical reduction processes in order to obtain the metals contained in the briquettes.

Title: Anti-skid hydraulic braking systems for vehicles
Inventor: FARR GLYN PHILLIP REGINALD
IPC: B60T8/42
Filed: 1985-06-26
Abstract: In an anti-skid braking system of the de-boost and pump to re-apply type, a solenoid-operated cut-off valve (5) is disposed between an expander piston (17) and a brake (2), and the cut-off valve (5) is operable independently of and separately from the expander piston (17). The cut-off valve (5) co-operates with a one-way valve (7) disposed between a master cylinder (1) and the brake (2) to hold the one-way valve (7) in an open position when the cut-off valve is in a closed position with the solenoid de-energised. This ensures that the one-way valve (7) can close only as a result of movement of the cut-off valve (5) into an open position which can occur only when the solenoid is energised in response to a skid signal. On termination of the skid signal fluid is displaced from the expander chamber (16, 21) by a cam driven pump (8) through a passage (31) and variable and fixed orifices (40/31) and (42). <IMAGE>

Title: Device for harmonising the optical axes of an optical sight
Inventor: RUGER RODERICH
IPC: G02B23/12
Filed: 1985-08-02
Abstract: In an optical sight comprising at least two optical instruments 2, 3 preferably having different frequency ranges, optical axis 10 of the first instrument 2 relative to the optical axis 11 of the second instrument 3 (and of each further instrument) forms an angle of 90 DEG , and a respective beam splitter 4, arranged at 45 DEG , lies in the point of intersection of these axes. A triple mirror 5 is arranged in an extension of the optical axis 11 of the second instrument 3. A reticle present in an image plane 7 of the first instrument 2 can be projected, together with a target 12 to be sighted, by way of the beam splitter 4 and the triple mirror 5 into image plane 7a of the second instrument 3. This observation can be effected in reverse direction because of the simultaneous reproduction of the reticle or aiming point present in the image planes 7 and 7a, the instruments 2 and 3 are automatically axis-harmonised, so that otherwise customary collimators or external test instruments can be dispensed with. <IMAGE>

Title: Optical state-of-polarisation modulator
Inventor: KING JONATHAN PAUL
IPC: G02B5/30
Filed: 1985-12-13
Abstract: An optical measurement system includes a polarisation modulator 18 that is switched between a number of polarisation states which are such that corresponding photodetector outputs can be combined to give a measurement signal that is independent of polarisation. It is shown that the polarisation states must be symmetrical on the Poincaré sphere such that they sum to the centre of the sphere. One such modulator comprises two magnetically-switched (Faraday effect) circularly-birefringent half-wave elements with an intervening unswitched linearly-birefringent quarter-wave plate, and has four states. The switched elements can alternatively be linearly-birefringent using the electro-optic effect, or can be liquid-crystal devices. The system is an optical-fibre reflectometer in which coherent light backscattered B.S. from a fibre under test 22 is heterodyned 16 with "local oscillator" light L.O. from laser diode 10. The outputs from photodetector 25 are squared and summed 28 overthefour modulator states. <IMAGE>

Title: Heat sensitive recording materials
Inventor: YAMAGUCHI JUN
IPC: G03C1/52
Filed: 1986-12-23
Abstract: Heat sensitive recording material is of the type containing in a sensitive layer a diazonium salt and a coupler (e.g. resorcinol) and optionally a basic substance which react to form a dye; the layer also contains o-toluenesulfonamide. At least one of the color-forming components is enclosed in microcapsules. e.g. of polyurethane or polyurea, which rupture or become permeable when heated; the making of polyurethane capsules is described, preferably by polymerizing from inside an oil drop. Capsule size is 20 microns or less. The sulfonamide can be inside or outside capsules or in the capsule wall. Amount by weight of the sulfonamide, per part of the coupler, is 0.01-10 parts. Other additives can be present to improve heat coloration or lower melting point in the layer. The sulfonamide improves the image density and storage life after recording with a facsimile or computer printer; the material is fixed by overall exposure.

Title: Missile nose fairing assembly
Inventor: DRANSFIELD ALFRED EDWARD
IPC: F42B15/36
Filed: 1987-05-01
Abstract: A separable nose fairing assembly for a guided missile 10 includes a forward, massive portion 16 slidably coupled to a rearward, light portion 20. Forward sliding movement of the massive portion 16 relative to the light portion 20 is limited by a stop 26. An explosive actuator 25 is operable to drive the forward portion 16 forwardly until an inwardly projecting lip 18 reaches the stop 26, whereupon the momentum transferred to the rearward portion 20 is sufficient to pull it off the missile 10 to expose a window 13. Due to the high ballistic coefficient of the assembly it follows a ballistic trajectory different from that of the missile, thus minimising the possibility of damage to the missile. <IMAGE>
