Title: Variable field of view scanning system
IPC: G02B26/10
Filed: 1973-05-14
Abstract: 1423257 Optical scanning TEXAS INSTRUMENTS Inc 14 May 1973 [19 June 1972] 22796/73 Heading H4F In an optical scanning system wherein radiation from an object 20 in a field of view is received by one face 26 of an oscillatory scanning mirror 30 and focused 32 on a detector 34, an afocal optical system 12 is provided for changing the field of view. As shown, system 12 comprises a convergent lens 14 and a convergent or divergent lens 16, and is rotatable about a point 18, so as to lie out of the optical path, position 14b, 16b for a normal field 52, or on the optical path for an increased field 54, position 14a, 16a or a decreased field 50, position 14, 16. The detector 34 comprises a line of contiguous infra-red detectors controlling a corresponding line 38 of light emitting diodes. The radiation therefrom, which may be visible, is directed on to the face of a vidicon 44 controlling a cathode-ray display tube 48, having been focused by lens 40 and scanned by a reverse face 28 of mirror 30. It is also possible for detector 34 and line 38 to consist of spaced elements, whereupon the mirror is tilted about an axis 58 at an angle to the scan axis 56, Fig. 2, to provide an interlaced scan. The mirror is driven about the axis 56 by a D.C. torque motor 62 including a stator 64 and rotor 66. A tachometer 76 including a stator 78 and rotor 80 provides a feedback signal for rate sensing. The angular velocity is kept substantially constant for each half oscillation, Fig. 3 (not shown). During the dead period when the mirror motion is reversing the appropriate one of a pair of solenoids 92 acts to tilt the mirror about axis 58 to its other position. With the aid of additional lenses and beam folding mirrors, the system of Fig. 1 may be mounted in a spherical housing itself mounted for pivoting about the pitch and yaw axes of an aircraft, Fig. 6 (not shown). In modifications of the afocal system 12, a fixed pair of lenses (152, 154) may act as a beam contracting system and a rotatable pair of lenses (158, 160) may be inserted by rotation to lie between the fixed lenses, so that the four lenses act as a beam expander, Figs. 7a and 7b (not shown). In Fig. 8 (not shown), a beam folding mirror lies before the scanning mirror, and the lenses of the afocal system may be linearly moved so as to lie on the optical path before and after the beam folding mirror, Fig. 8 (not shown).

Filed: 1936-08-19
Abstract: 480,593. Motor - vehicle driving - gear. STEWART, C. E. Aug. 19, 1936, No. 22865. [Class 79 (ii)] [Also in Groups XXIV and XXIX] Automatic change-speed gear for motor vehicles comprises a driven axle 1, Fig. 3, a gearbox 8 for each road wheel, reduction gear between the axle and each wheel, and automatic clutches between the axle and each wheel adapted to cut out the reduction gear to provide a direct drive. The automatic clutches may be hydraulic couplings or centrifugal clutches. The engine A drives the axle shaft 1 through a clutch B and gearing D. In the construction shown in Fig. 1 one-way clutches are provided between the axle 1 and each wheel so that either wheel can overrun the axle. Reversing gear is also provided in each gear-box 8. The axle shaft 1 is coupled by a one-way clutch 12 to a sleeve 10 which drives the road wheel 44 through reduction gear 11, 20 and 31, 42, a one-way clutch 23 being provided so that gear 31 and its sleeve 30 can over-run the gear 20. A sleeve 5, driven from sleeve 10 at the same speed through gears 11, 20 and 21, 50, is splined to the driving member 6 of an hydraulic coupling the driven member 46 being fixed to the road wheel. A cone clutch member 7 adapted to engage a coned surface 45 on the wheel 44 is slidably mounted on the sleeve 5 under control of a spring 71 and sloping clutch teeth 70, 60 formed respectively on the cone 7 and the member 6. When the engine starts to drive the vehicle, the drive is transmitted to the wheel through the double reduction gears 11, 20 and 31, 42, the driving member 6 of the hydraulic clutch over-running the driven member 46 fixed to the road wheel. As the speed increases the hydraulic clutch gradually takes up the drive and drives the wheel at an increasing gear ratio, the sleeve 30 now over-running the gear 20. Finally the sloping clutch teeth 60, 70 cause the cone member 7 to be moved axially until it engages the surface 45 and couples the sleeve 5' and member 6 directly to the wheel. For reverse gear the sleeve 30 is slid along its shaft 3 until gear 31 is disengaged from gear 42 and engages with an idler 9 integral with a gear 9a in permanent mesh with gear 42. In reverse gear the sleeve 5 and hydraulic clutch member 6 are not driven, the gear 21 being disengaged from gear 50.

Title: Improvements in roasting of ores
Inventor: THORNHILL PHILIP GEORGE
IPC: C22B1/10
Filed: 1959-07-03
Abstract: <PICT:0863404/III/1> <PICT:0863404/III/2> In a method for roasting ores in a fluidized bed, a slurry of ore 18 (Fig. 1) is fed by a pump 22 to a feed gun 30 to which is supplied compressed air from a compressor 38, the slurry and compressed air entering a barrel 144 (Fig. 2) of the feed gun 30 by inlets 28 and 44 so that masses of slurry separated by volumes of air pass down the barrel 144 and through an annular opening 182 formed by the lower end of the barrel and a frustoconical member 180 arranged so that the annular opening 182 restricts the flow of slurry causing a momentary build-up of pressure in the barrel 144, which pressure forces the slurry through the opening with an explosive impulse breaking the slurry into droplets which are sprayed downwardly in a hollow cone-like stream 186 (Fig. 1) on to the fluidized bed 110, the droplets being dried by hot gases rising from the bed to form agglomerates of ore before they reach the bed.  The discharge of slurry from the annular opening results in a momentary drop in pressure in the barrel; the pressure is then built up again by the entry of more slurry into the annular opening and the process is repeated resulting in a rapid pulsating action.  The bed is fluidized by air from nozzles 94, and gases are removed by a pipe 116, fines being removed in cyclones 118 and 120 and returned to the bed.  Burners 1361 and 1381 are used to initiate the roasting.  Pyrrhotite is mentioned as an ore which may be roasted.  The ore may be slurried with water containing sodium sulphate.  Specification 769,269 is referred to.

Filed: 1953-09-11
Abstract: 722,565. Automatic D.C. control systems. SIEMENS BROS. & CO., Ltd. Sept. 11, 1953 [Sept. 12, 1952], No. 22940/52. Class 38 (4). [Also in Group XXXIX] In a converter for supplying a constant direct current to a load irrespective of changes in supply voltage or load resistance, saturable chokes CHA, CHB in series with the load are controlled by a magnetic amplifier AMP which has two control windings, one of which is shunted by a non-linear resistance NLR connected in series opposing relationship so that there is a large percentage variation of controlling ampere turns in response to a comparatively small change of control current. The load, in this case a group of submarine repeaters, is fed with alternating current from terminals TA over a transformer TRB, and the current through load windings (1) which is rectified and applied to saturating windings (II) of the chokes CHA, CHB, is controlled by the resultant ampere turns arising from the control windings and the feed-back windings (II). Manual adjustment of the current can be effected by adjusting potentiometer YB. The converter includes a supply filter SF and a resistance YA to ensure a minimum amplifier output impedance. Characteristics of a typical converter are described with reference to Figs. 2, 3 (not shown).
