Title: A Luminous Indicating Device for the Night Landing of Flying Machines.
Inventor: HOPPER JOHN GEORGES
IPC: B64D47/04
Filed: 1917-02-12
Abstract: 127,009. Hopper, J. G. Feb. 10, 1916, [Convention date]. Lamp signals.-A device to facilitate the landing of aircraft by night, by enabling the approximate height to be found quickly, comprises two lightprojectors 3, 4 placed at a known distance apart and throwing beams in a substantially vertical plane. The projector 3 is fixed to throw a beam at right-angles to the plane 1, and the projector 4 is mounted pivotally so that it can be rotated by suitable gearing from the pilot's seat. In use, the projector 4 is rotated until the spots of light made on the ground by the beams are coincident, when the height is found from the angular position of the projector, which may be read off from a scale on a dial within view of the pilot. A sighting- tube may be provided within reach of the pilot for use instead of either projector should one be out of order. To avoid an elongated spot of light due to the beam 7<1> striking the ground at an angle, a suitable shutter may be provided on the projector 4.

Title: Electrical system for reel motors in strip rolling mills and the like
IPC: B21B37/54
Filed: 1956-01-24
Abstract: 778,763. Automatic tension control systems. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Jan. 24, 1956 [Jan. 25, 1055], No. 2260/56. Class 38 (4). [Also in Group XXXVII] A shown, the armature 2 of a reel motor is supplied from a constant-current generator 7 in series with the armature 4 of the driving motor for the final rolling stage of a mill dealing with strip or like material 6. An exciter 12 for the reel motor has a shunt field winding 16 as well as field windings 17, 18 which oppose each other and are responsive to the armature voltages of the reel motor and driving motor respectively. Thus, the ratio between the armature voltages remains at a fixed value at all speeds of the reel motor, whereby the power of the reel motor is kept proportional to the strip speed and the pull in the strip is maintained at a constant value. The tension can be adjusted by means of rheostats 20, 21 and is influenced by adjustment of rheostat 23, so that alteration of the setting of the rheostat 23 calls for readjustment of the other rheostats. The speed of the rolling stage and reel is controlled by resistor 11 in the field circuit of the generator 7, the rheostats 20, 21 requiring re-adjustment during periods of acceleration or retardation if the strip tension is to be kept constant during these periods. In a modification, the field winding of the reel motor is connected to an A.C. source through a rectifier and a transductor having control windings similar to the windings 16, 17, 18. In another arrangement, the excitation of the machine 12 comprises a constant component and a component determined by a transductor such as described above. The generator 7 may not necessarily be of the constant-current type but may be compounded to provide a suitable characteristic for the material being worked upon.

Title: Improvements in or relating to the production of magnesium by the condensation of its vapours
IPC: C22B26/22
Filed: 1946-01-24
Abstract: 612,617. Distilling magnesium. SOC ELECTRO - METALLURGIQUE DU PLANET. Jan. 24, 1946, Nos. 2422 and 2423. Convention dates, July 12, 1941, and June 12, 1942. [Class 82(i)] A method for the production of magnesium by the condensation of its vapour produced during the reduction of a magnesiferous ore by heating in a furnace under vacuum conditions, comprises causing the metal vapour to pass in succession through two condensing zones respectively maintained under different conditions of both temperature and pressure such that any vapour condensed in the first zone will yield liquid metal and any vapour reaching the second zone will yield solid metal. The pressure difference may be automatically created by causing the vapour to undergo a loss in pressure in passing from the first to the second zone. In the form shown, the first zone 4, communicating with the reduction chamber 1, is connected with a second zone 8 by a restricted orifice 7, and the zone 8 communicates directly with the vacuum source 18 by the aperture 15. The first zone may be at a temperature and pressure of the order of 660 ‹C. and 2mm. of mercury, and the second zone at slightly lower than 400‹C. and at a pressure equal to the vapour tension of magnesium at that temperature. The first zone or chamber has a discharge orifice 30 leading to a fluid-tight chamber containing an ingot mould 26. The mould chamber may be kept, in its upper part, at the same temperature as chamber 4 and the lower part may be at room temperature, and the mould may contain oil; or at a temperature such that the metal collected in the mould remains liquid. The mould chamber may be heat-insulated and even heated, if desired. Means may be provided to cool the mould chamber after filling the mould and prior to its withdrawal, e.g. cooling jackets adapted to be substituted for heat insulation or heating means.

Filed: 1919-02-05
Abstract: 138,169. Braly, N. B. Feb. 5, 1919. Elastic-grip joints. - Relates to couplings for mine-ventilation hose-pipes of the type described in Specification 106,219. The expansion and contraction of the coupling - rings is specifically limited to an extent which prevents one ring from passing through another when the rings are parallel. Apart from this specific limitation, the construction is as described in the above-mentioned Specification, and comprises a flanged divided ring 7 with overlapping ends having slots 9 which register. The ends are held together so as to allow expansion and contraction of the ring with a telescopic sliding action of the ends, by means of a member 10 having tongues 11 which are passed through the registering slots and then bent over as at 12. Identical rings are provided at each end of a length of hose-pipe, and each is housed in a hem at the pipe end. The limits of contraction and expansion are determined by the relative width of tongue 11 and length of slot 9. To assemble, the rings at the adjacent ends of two pipe lengths are presented to one another at an angle, and one ring is forced through the other by slight deformation of one or both. The rings are then brought parallel with the inner ring interlocking behind the terminal flange of the outer ring.

Abstract: 284,610. British Thomson-Houston Co., Ltd., (Assignees of Seeley, H. T.). Jan. 31, 1927, [Convention date]. Synchronizing dynamo-electric machines.-The spring 9 of a governor 8 of a prime-mover 4 driving an alternator 5 is adjusted by a synchronizing motor 11 so that the alternator 5 reaches a frequency slightly greater than the system 1, whereupon a circuit breaker 6 is closed either automatically or manually, and thereafter the motor 11 operates to cause the alternator 5 to take its full load. Synchronous motors 17, 18, connected respectively to the alternator 5 and system 1 drive, through gearing, elements 15, 16, the. gearing being such that the elements 15, 16 only run at the same speed when the motor 17 is running slightly faster than the motor 18. Initially, contacts 21, 23 on the elements 15, 16 are in engagement, thus completing a circuit, which is rendered intermittent by the collector ring on the element 16, through a relay 25, which periodically closes to cause the motor 11 to set the governor for increase of speed of the prime mover 4. If the frequency of the alternator 5 exceeds that of the system 1 by more than a predetermined amount, contacts 21, 23 separate and contacts 22, 23 engage to energize a relay 24 to decrease the speed of the prime-mover 4. after the switch 6 has been closed, the motors 17, 18 run at the same speed and therefore contacts 21, 23 are kept in engagement so that the motor 11 continues to open the governor, so as to put the alternator under full load, until a limit switch 26 is opened to de-energize the relay 25. The relay 24 may have a delay action in opening its contacts, or the motor 11 may be designed to run in the " decrease " direction quicker than in the other direction.

Title: Attitude control systems

Filed: 1975-01-24
Abstract: 1478792 Automatic control of attitude HUGHES AIRCRAFT CO 24 Jan 1975 [25 Jan 1974] 3206/75 Heading G3R The attitude of a vehicle 1 in space, e.g. a satellite, having a rotatable momentum wheel 2 having a single degree of freedom is controlled by periodic operation of a plurality of jet thrusters 80, 90 by an electronic circuit which is not responsive to rotational action of the wheel. The invention is concerned with reducing rotations about the roll axis X, directly, and the yaw axis Z by, gyroscopic coupling, associated with the fact that the two thrusters used are offset as shown by the angle aj. The earth is to the right in Fig. 1. The coupling is described mathematically. The attitude is sensed by an infrared horizon sensor 10 connected to a low pass filter in the electronic circuit, Fig. 2 (not shown). The filter output is converted into logic form and sampled by a switch at twenty times the nutation frequency; the resulting pulses are fed to fifteen stage shift registers which produce such a delay that, when the output of the last stage is applied to jet 80 or 90, according to direction of error, the resulting thrust is applied at the best point of the nutation cycle. The circuit includes a dead band which is automatically widened according to the number of errors which fall outside it in a cycle. This is achieved by connecting the first ten stages of a register to an adder, whose output thus depends on the number of errors registered and which accordingly widens the dead band. The effect is to inhibit jet pulsing for small errors. None of the circuits are described in detail.
